[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0019] like Figures 1 to 3 As shown, a workbench locking mechanism includes a guide rail 1, a workbench 2, and a wedge block 3. The workbench 2 and the guide rail 1 are slidably matched, and the workbench 2 can slide on the guide rail 1. A wedge-shaped space is formed between the workbench 2 and the guide rail 1, and the wedge block 3 is arranged in the wedge-shaped space. A push adjustment mechanism is arranged between the wedge block 3 and the workbench 2, and the wedge block 3 is driven to move in the wedge-shaped space by the push adjustment mechanism. The cross sections of the wedge-shaped space and the wedge block 3 are both right-angled trapezoids.

[0020] In the utility model, the workbench 2 and the guide rail 1 are slidably matched. When the workbench 2 slides to the target position, the wedge block 3 is driven to move into the wedge-shaped space through the push adjustment mechanism, so that the wedge block 3 is wedged between the guide rail 1 and the workbench 2, thereby locking the workbench 2 and preventing the workbench 2 from moving along the guide rail 1, thereby firmly locking the workbench 2. The utility model realizes stable locking of the workbench 2 through the wedge block 3, the overall structure is simple and reliable, the wedge block 3 has strong self-locking performance, and good locking stability.

A plug hole 11 is provided in the circumferential direction of the first push nut 5 and the second push nut 6. By rotating the first push nut 5 and the second push nut 6, the first push nut 5 and the second push nut 6 are moved along the length direction of the screw rod 4, thereby driving the wedge block 3 to move. When rotating the first push nut 5 and the second push nut 6, one end of a rod (such as a metal rod) can be inserted into the plug hole 11, and torque can be conveniently applied to the first push nut 5 and the second push nut 6 through the rod.

[0022] A threaded hole is provided on the wedge block 3, and one end of the screw rod 4 is threadedly connected in the threaded hole.
