In this utility model, the housing is clamped by setting the support member 7, the limiting component 6 and the clamping component, and the driving member 3 drives the left clamping member 4 and the right clamping member 5 to move at the same time. By using a single power unit, the clamping task can be realized, which reduces the equipment input cost, and this fixture has the advantages of simple structure and strong practicability.

[0029] Among them, the left clamping member 4 and the right clamping member 5 have the same structure, which is convenient for manufacturing and assembly. Since the left clamping member 4 and the right clamping member 5 have the same structure, in this embodiment, only the specific structure of the left clamping member 4 will be disassembled and explained.

[0030] See Figure 4 , the left clamping member 4 includes a fixed column 40 and a cantilever 42 pivotally connected to the fixed column 40. A push rod 41 is passed through the fixed column 40. One end of the push rod 41 is arranged below the cantilever 42, and the other end is arranged above the driving member 3. By driving the driving member 3 to drive the push rod 41 to move up and down, the cantilever 42 is driven to rotate, so as to realize the clamping of the upper box body 20. The structure is simple and the clamping is stable.

[0031] Among them, a cavity is arranged inside the fixed column 40, a spring is arranged below the cantilever 42, the spring is placed in the cavity, a U-shaped groove 43 is arranged on the side surface of the fixed column 40, and the cantilever 42 can slide along the U-shaped groove 43.
