A police baton including an outer tube and an inner tube connected in a telescoping manner, and clutch locking and releasing mechanisms provided at first ends of the inner and outer tubes respectively. When the inner tube is moved outward of the outer tube until the first end of the inner tube press
A police baton including an outer tube and an inner tube connected in a telescoping manner, and clutch locking and releasing mechanisms provided at first ends of the inner and outer tubes respectively. When the inner tube is moved outward of the outer tube until the first end of the inner tube presses against a second end of the outer tube, a clutch locking block of the clutch locking mechanism moves laterally outward due to an elastic force and is embedded into a retaining groove on the outer tube, thereby forming a long stick. When a releasing shaft of the releasing mechanism is inserted into a releasing groove on the clutch locking block, the clutch locking block is moved laterally inward and released from the retaining groove, thereby allowing the inner tube to move toward the outer tube for forming a short stick.

A police baton having an outer tube and an inner tube telescopically connected to the outer tube, and an expansion/collapse control mechanism comprising: a clutch locking mechanism provided adjacent to a first end of the inner tube, the clutch locking mechanism comprising at least a clutch lockin
1. A police baton having an outer tube and an inner tube telescopically connected to the outer tube, and an expansion/collapse control mechanism comprising: a clutch locking mechanism provided adjacent to a first end of the inner tube, the clutch locking mechanism comprising at least a clutch locking block and at least an elastic member, the elastic member having two ends respectively pressed against the clutch locking block and an inner wall of the inner tube, the inner tube having a second end which can pass through the outer tube by way of a first end of the outer tube and be exposed from a second end of the outer tube, a retaining groove being provided on an inner wall of the outer tube and adjacent to the second end of the outer tube, wherein when the inner tube is forced to move outward of the second end of the outer tube such that the first end of the inner tube is pressed against the second end of the outer tube, the clutch locking block is moved laterally outward by an elastic force of the elastic member and becomes embedded in the retaining groove; anda releasing mechanism fixedly provided at the first end of the outer tube and comprising a releasing shaft, the releasing shaft having a first end to be forced by a user and a second end extendable into the inner tube by way of the first end of the outer tube so that, when the clutch locking block is embedded in the retaining groove, the second end of the releasing shaft can be inserted into a releasing groove formed on the clutch locking block by pressing the first end of the releasing shaft such that the clutch locking block is moved laterally inward, released from the retaining groove, and no longer embedded in the retaining groove, allowing the first end of the inner tube to move toward the first end of the outer tube when being forced. 2. The police baton of claim 1, wherein the releasing mechanism further comprises a spring provided between an outer wall of the releasing shaft and the inner wall of the outer tube, the first end of the releasing shaft is exposed from the first end of the outer tube, and the second end of the releasing shaft is extendable into the outer tube by way of the first end of the outer tube so that, when the clutch locking block is embedded in the retaining groove, the second end of the releasing shaft can be inserted into the releasing groove by pressing the first end of the releasing shaft such that the clutch locking block is moved laterally inward, released from the retaining groove, and no longer embedded in the retaining groove. 3. The police baton of claim 2, wherein the clutch locking block has an inner surface provided with a concavely curved portion forming the releasing groove. 4. The police baton of claim 3, wherein the inner tube has a rim adjacent to the first end of the inner tube and provided with at least a through hole, and the clutch locking block is pivotally provided in, and movable back and forth through, the through hole so that the clutch locking block can protrude partially from a surface of an outer wall of the inner tube and be embedded in the retaining groove or the clutch locking block can no more protrude from the surface of the outer wall of the inner tube and is therefore no longer embedded in the retaining groove. 5. The police baton of claim 4, wherein the rim of the inner tube is provided with at least a locking hole, one said end of the elastic member is pressed against the clutch locking block, the other end of the elastic member extends into the locking hole, and the locking hole is fastened with a locking component so as for the elastic member to be positioned between the clutch locking block and the locking hole, and for the clutch locking block to protrude partially from the surface of the outer wall of the inner tube and be embedded in the retaining groove due to the elastic force of the elastic member. 6. The police baton of claim 5, wherein the releasing shaft is provided with a connecting block adjacent to the first end of the releasing shaft, the connecting block is fixedly connectable to the outer tube, and the spring has an end pressing against the connecting block. 7. The police baton of claim 5, wherein the outer tube is provided with a connecting block, and the spring has an end pressing against the connecting block. 8. The police baton of claim 1, wherein the releasing mechanism further comprises a button and a spring, the button has a first end exposed from the first end of the outer tube, the spring is provided between a second end of the button and the first end of the releasing shaft, and the second end of the releasing shaft is extendable into the outer tube by way of the first end of the outer tube so that, when the clutch locking block is embedded in the retaining groove, the second end of the releasing shaft can be inserted into the releasing groove by pressing the first end of the button such that the clutch locking block is moved laterally inward, released from the retaining groove, and no longer embedded in the retaining groove. 9. The police baton of claim 8, wherein the clutch locking block has an inner surface provided with a concavely curved portion forming the releasing groove. 10. The police baton of claim 9, wherein the inner tube has a rim adjacent to the first end of the inner tube and provided with at least a through hole, and the clutch locking block is pivotally provided in, and movable back and forth through, the through hole so that the clutch locking block can protrude partially from a surface of an outer wall of the inner tube and be embedded in the retaining groove or the clutch locking block can no more protrude from the surface of the outer wall of the inner tube and is therefore no longer embedded in the retaining groove. 11. The police baton of claim 10, wherein the rim of the inner tube is provided with at least a locking hole, one said end of the elastic member is pressed against the clutch locking block, the other end of the elastic member extends into the locking hole, and the locking hole is fastened with a locking component so as for the elastic member to be positioned between the clutch locking block and the locking hole, and for the clutch locking block to protrude partially from the surface of the outer wall of the inner tube and be embedded in the retaining groove due to the elastic force of the elastic member. 12. The police baton of claim 11, wherein the releasing shaft is provided with a connecting block adjacent to the first end of the releasing shaft, the connecting block is fixedly connectable to the outer tube, and the spring has an end pressing against the connecting block. 13. The police baton of claim 11, wherein the outer tube is provided with a connecting block, and the spring has an end pressing against the connecting block.
