[0011] Preferably, a threaded rod is rotatably connected to the top of the base, and the threaded rod is threadedly connected to the fixing plate.

[0012] Preferably, the base is equipped with a motor, and the output end of the motor is fixedly connected to the threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Place the locking rod to be welded inside the fixed housing, move the slider to the center, and the clamping housing drives the clamping rod to approach the locking rod. The clamping rod is rotatably connected to the clamping housing, and the pressing blocks at both ends of the clamping rod abut against the side wall of the locking rod, which can realize multi-point clamping of the locking rod and ensure the stability of clamping and fixing.

[0015] 2. Depending on the size of the locking rod to be welded, rotate the threaded rod to move the fixing plate away from or center it, thereby adjusting the position of the clamping assembly to accommodate container locking rods of different lengths.

[0016] In summary, this utility model overcomes the shortcomings of the prior art, has a reasonable design, and improves the stability of clamping by using the pressure block to clamp the locking rod at multiple points, which facilitates subsequent welding work and has high social use value and application prospects.
