The sliding rods 34 are sleeved with The spring 3 42 allows the engagement of the end face ratchet 2 33 and the end face ratchet 1 32 to be disengaged intermittently in the direction of rotation when the pressure rod 3 is lowered. However, if the pressure rod 3 is rotated in the opposite direction, it is stuck, so that the pressure rod 3 can only be rotated in the direction of lowering, thereby preventing the pressure rod 3 from loosening when it is lowered.

[0045] During the rise and fall of the pressure rod 3, the gas spring 25 pushes or pulls the connecting plate 3 26, thereby buffering the rotation of the fixed tube 5 by the buffer of the second rotating shaft 43, and when the pressure rod 3 is installed, the two ends of the bottom of the pressure rod 3 are inserted into the slots 6 on the fixed tube 5, and then the pressing rod 44 is pressed, so that the pressure plate 31 presses against the second meshing plate 28, so that the first meshing plate 27 and the second meshing plate 28 are disengaged, so that the spur gear 18 can rotate, and then under the action of the spring 11, the connecting plate 10 is squeezed, so that the connecting plate 10 slides on the limit rod 19, and also drives the first tooth plate 14 and the second tooth plate 15 to interact. The first and second gear plates 14 and 15 are moved away from each other, so that the insertion rod 7 is inserted into the sliding hole 8 and the socket 20 opened at the bottom of the pressure rod 3, thereby fixing the pressure rod 3 and buffering the insertion rod 7 through the pad 9. When the pressure rod 3 needs to be removed, the pressing rod 44 is pressed to make the spur gear 18 rotate, and then the knob 16 is turned to rotate the spur gear 18, driving the first gear plate 14 and the second gear plate 15 to approach each other, driving the insertion rod 7 out of the socket 20, and then releasing the pressing rod 44. Under the action of the telescopic rod 29 and the spring 2 30, the first meshing plate 27 and the second meshing plate 28 are meshed and fixed again, so that the pressure rod 3 can be pulled out.
