[0003] The existing lifting device is usually fixed by embedding the clamping column into the hole during use, and this kind of mode has limitations when adjusting the lifting height, that is, only gear adjustment can be carried out, which leads to inconvenience during use. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a press multi -positioning lifting device, which has the advantages of adjusting the lifting position at any position, and solves the problem of limitation of only gear adjustment when adjusting the height of the current lifting mechanism.

[0007] Preferably, the top end of the threaded rod is rotationally connected with a clamping plate, and the bottom end is fixedly connected with a handle.

[0008] Preferably, the sliding plate is attached to the outer edge surface of the guide rod, and the side of the sliding plate facing the guide rod is provided with a support plate extending into the guide rod, a hole is formed in the support plate for rotation of the limiting mechanism, and a positioning plate is arranged above the support plate.

[0009] Preferably, the top of the skateboard is provided with a base for connection to the support mechanism. A vertical plate is provided on the side of the base facing the guide mechanism. Several limiting plates are symmetrically provided on the side of the vertical plate. Several rollers are provided on the outer side of each limiting plate. Rollers two that fit one side of the guide groove are provided on the side of the vertical plate, and rollers three that fit the other side of the guide groove are also provided. Rollers two and three are perpendicular to each other.

[0010] Preferably, the limiting mechanism includes a driven plate, a pressing plate is provided on the outer side of the driven plate, a U-shaped plate is provided on the inner side, and a rotating shaft is rotatably connected to the end of the U-shaped plate away from the driven plate, and a spiral spring is sleeved on the outer edge of the rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a driven plate, a pressing plate, a U-shaped plate, a second rotating shaft, a spiral spring, a support, a bracket, and a limiting post, allows the driven plate to rotate around the second rotating shaft when the pressing plate is pressed. This, in turn, causes the support at the top of the spiral spring to move, and the bracket then moves the limiting post, releasing the limit between the guide rod and the sliding mechanism. The sliding mechanism slides on the guide rod until it reaches the designated position. Then, the pressing plate is released, and the spiral spring drives the driven plate to reset, causing the limiting post to re-abut against the guide rod, thus fixing the sliding mechanism. This allows for lifting and lowering at any position, making it quite practical.

[0014] 2. This utility model, by setting up a vertical plate, a limiting plate, roller one, roller two, and roller three, with roller one on the outer side of the limiting plate conforming to the inner edge of the guide groove, and roller two and roller three conforming to the inner edge of the guide groove, can reduce the friction between the sliding mechanism and the guide groove when adjusting the height of the sliding mechanism, thus facilitating height adjustment.
