When the movable column 2 is limited and fixed, the swivel 5 can be rotated. The rotation of the swivel 5 can drive the inclined slot 8 to rotate. When the inclined slot 8 rotates, it can drive the movable rod 9 to move linearly, thereby pushing the connecting plate 11 to move. The movement of the connecting plate 11 can drive the insert block 12 to move. When the insert block 12 is fully inserted into the interior of the slot 7, the movable column 2 can be limited and fixed. When it is necessary to loosen and adjust the length of the movable column 2, it is only necessary to rotate the swivel 5 in the opposite direction. The swivel 5 rotates in the opposite direction.

When adjusting the length of the movable column 2, the rotation of the knob 6 can drive the tooth column 17 to rotate through the rotating shaft 16. The rotation of the tooth column 17 can drive the rack 21 to move, thereby driving the support column 22 to move. The movement of the support column 22 can be stably moved by the mutual cooperation of the slider 19 and the slide groove 20. Then the support column 22 will drive the movable column 2 to move, thereby driving the threaded column 3 to move, and then the movable column 2 is limited and fixed by rotating the swivel 5. When the movable column 2 is limited and fixed, the rotation of the swivel 5 can drive the inclined slot 8 to rotate. When the inclined slot 8 rotates, It can drive the moving rod 9 to move in a straight line, thereby pushing the connecting plate 11 to move. The movement of the connecting plate 11 can drive the insertion block 12 to move. When the insertion block 12 is fully inserted into the interior of the slot 7, the moving column 2 can be limited and fixed. When it is necessary to loosen and adjust the length of the moving column 2, it is only necessary to rotate the swivel 5 in the opposite direction. The swivel 5 rotates in the opposite direction. Similarly, the moving block 10 can be pulled outward. The moving block 10 can drive the insertion block 12 to be pulled outward through the connecting plate 11. When the insertion block 12 is disengaged from the interior of the slot 7, the length of the moving column 2 can be adjusted. Limiting and fixing the moving column 2 can effectively prevent loosening and falling off due to vibration, impact or long-term use.
