An adjustable holding frame mainly includes a first bar, a second bar and an adjusting means. The second bar has one end fastened to a lump element which is pivotally located in the adjusting means. The adjusting means is mounted onto the first bar and has a helical structure to adjust the position of a seat in the adjusting means. Thereby releasing or fastening of the lump element of the second bar can be controlled to adjust the posture condition of the holding frame.

What is claimed is: 1. An adjustable holding frame, comprising: a first bar; a second bar which has one end fastening to a lump element; and an adjustable means which includes: a base which is fastened to the first bar and an upper surface forming a first sloped surface portion which is a helical structure surrounding the upper surface at a gradually increasing height; a housing which is hollow and mounted onto the base to form a hollow portion with the base, and has an upper opening on a top end surface leading to the hollow portion, the hollow portion having an inner surface which has a portion forming an upper coupling surface, the housing having a notch on one side leading to the hollow portion; and a seat which is a cylinder and is slidable in the hollow portion of the housing, and has a top end surface forming a lower coupling surface corresponding to the upper coupling surface to mate the contour of the lump element, and a bottom end surface forming a second sloped surface portion which is another helical structure surrounding the bottom end surface at a gradually increasing height corresponding to the first sloped surface portion, the seat having a handle on one side extended radially outwards corresponding to the location of the notch; wherein the hollow portion limits the sliding movement of the seat within a range of a first position and a second position, and the first sloped surface portion and the second sloped surface portion selectively set the seat at either a first position or a second position; at the first position the lower coupling surface and the upper coupling surface compressing and anchoring the lump element; at the second position the lower coupling surface and the upper coupling surface releasing the lump element. 2. The adjustable holding frame of claim 1, wherein the second sloped surface portion and the first sloped surface portion form a complementary structure. 3. The adjustable holding frame of claim 2, wherein the first sloped surface portion on the base is a helical structure indented into the surface thereof and the second sloped surface portion on the bottom of the seat is another helical structure extended outside the surface thereof. 4. The adjustable holding frame of claim 1, wherein the notch has two sides forming two limit positions of rotation of the seat, one limit position allowing the seat to raise to compress and anchor the lump element, another limit position allowing the seat to lower to release the lump element. 5. The adjustable holding frame of claim 1, wherein the lump element is spherical. 6. The adjustable holding frame of claim 1, wherein the first bar has a bottom end mounting onto to a base dock. 7. The adjustable holding frame of claim 1, wherein the second bar has a top end fastening to a holding dock. 8. An adjustable holding frame, comprising: a first bar; a second bar which has one end fastening to a lump element; and an adjustable means which includes: a base which is fastened to the first bar; a housing which is hollow and mounted onto the base to form a hollow portion with the base, and has an upper opening on a top end surface leading to the hollow portion, the hollow portion having an inner surface which has a portion forming an upper coupling surface and a first sloped surface portion which has an internal threaded structure surrounding the inner surface of the housing, the housing having a notch on one side leading to the hollow portion; and a seat which is a cylinder and movable vertically in the hollow portion of the housing, and has a top end surface forming a lower coupling surface corresponding to the upper coupling surface to mate the contour of the lump element, and a bottom end surface forming a second sloped surface portion which has an external threaded structure surrounding the outer surface of the seat and corresponding to the first sloped surface portion, the seat having a handle on one side extended radially outwards corresponding to the location of the notch; wherein the hollow portion limits the sliding movement of the seat within a range of a first position and a second position, and the first sloped surface portion and the second sloped surface portion selectively set the seat at either a first position or a second position; at the first position the lower coupling surface and the upper coupling surface compressing and anchoring the lump element; at the second position the lower coupling surface and the upper coupling surface releasing the lump element. 9. The adjustable holding frame of claim 8, wherein the second sloped surface portion and the first sloped surface portion form a complementary structure. 10. The adjustable holding frame of claim 9, wherein the first sloped surface portion on the base is a threaded structure indented into the surface thereof, and the second sloped surface portion on the bottom of the seat is another threaded structure extended outside the surface thereof. 11. The adjustable holding frame of claim 8, wherein the notch has two sides forming two limit positions of rotation of the seat, one limit position allowing the seat to raise to compress and anchor the lump element, another limit position allowing the seat to lower to release the lump element. 12. The adjustable holding frame of claim 8, wherein the lump element is spherical. 13. The adjustable holding frame of claim 8, wherein the first bar has a bottom end mounting onto to a base dock. 14. The adjustable holding frame of claim 8, wherein the second bar has a top end fastening to a holding dock.
