A foldable treadmill includes a base for running or walking, a frame set pivotally connected with the base, and a folding mechanism for folding the frame set. The folding mechanism has a control assembly and a sliding rod connected with the frame set and capable of being locked or released by the control assembly. When the control assembly locks the sliding rod at a first position, the frame set cannot be rotated, and when the control assembly releases the sliding rod, the frame set can be rotated to a storage position thus pulling the sliding rod to a second position.

1. A foldable treadmill, comprising: a base for running or walking;a frame set pivotally connected with the base; anda first folding mechanism, comprising: a control assembly; anda sliding rod with an end being connected with the frame set;wherein the sliding rod is capable of being locked or released by the control assembly; when the control assembly locks the sliding rod at a first position, the frame set cannot be rotated, and when the control assembly releases the sliding rod, the frame set can be rotated to a storage configuration whereby the sliding rod is pulled to a second position; andwherein the control assembly comprises:a tube, having a side wall with an opening, a portion of the sliding rod being arranged within the tube;a fixing member, passing through the opening of the tube and contacting with the sliding rod; andat least a torsion spring having a first end and a second end, the sliding rod passing through the torsion spring, wherein the first end of the torsion spring connects with the inner wall of the tube, and the second end of the torsion spring connects with the fixing member, so that the torsion spring provides a torsion to press the fixing member against the sliding rod and thus lock the sliding rod. 2. The foldable treadmill as set forth in claim 1, wherein the end of the sliding rod pivotally connects with the frame set. 3. The foldable treadmill as set forth in claim 2, wherein the frame set fixes with a triangular member, and the end of the sliding rod pivotally connects with a shaft of the triangular member. 4. The foldable treadmill as set forth in claim 1, wherein the control assembly comprises two torsion springs respectively arranged at a right side and a left side of the fixing member. 5. The foldable treadmill as set forth in claim 1, wherein the end of the sliding rod pivotally connects with the frame set, and the other end of the sliding rod comprises a cap nut to limit the displacement of the sliding rod. 6. The foldable treadmill as set forth in claim 1, wherein the first folding mechanism further comprising: a handle or a puller; anda cable having one end connecting with the handle and the other end connecting with the fixing member;wherein the handle or the puller provides a force to cancel the torsion of the torsion spring, so that the sliding rod is released. 7. The foldable treadmill as set forth in claim 1, further comprising a second folding mechanism having the same components as the first folding mechanism, the first folding mechanism and the second folding mechanism being arranged at a left side and a right side of the base, respectively. 8. A foldable treadmill, comprising: a base for running or walking;a frame set comprising a first post and a second post pivotally connected with the base, respectively;a first folding mechanism, comprising a first control assembly and a first sliding rod with an end being connected with the frame set, wherein the first sliding rod is capable of being locked or released by the first control assembly; anda second folding mechanism, comprising a second control assembly and a second sliding rod with an end being connected with the frame set, wherein the second sliding rod is capable of being locked or released by the second control assembly;wherein the frame set cannot be rotated when the first control assembly locks the first sliding rod at a first position and the second control assembly locks the second sliding rod at a first position, and wherein the frame set can be rotated when the first control assembly releases the first sliding rod and the second control assembly releases the second sliding rod, such that the frame set is rotated to a storage configuration corresponding to movement of the first sliding rod and the second sliding rod to a second position; andwherein the first control assembly comprises:a first tube, having a side wall with an opening, a portion of the first sliding rod being arranged within the first tube;a first fixing member, passing through the opening of the first tube and contacting with the first sliding rod; andat least a first torsion spring having a first end and a second end, the first sliding rod passing through the first torsion spring, wherein the first end of the first torsion spring connects with the inner wall of the first tube, and the second end of the first torsion spring connects with the first fixing member, so that the first torsion spring provides a torsion to press the first fixing member against the first sliding rod and thus lock the first sliding rod. 9. The foldable treadmill as set forth in claim 8, wherein the end of the first sliding rod and the end of the second sliding rod pivotally connect with the frame set.
