[0031] Embodiment Two

[0032] Refer to Figures 1 to 4 , and on the basis of Embodiment One, it is further obtained that the adjusting mechanism 4 includes a support block 41. The support block 41 is fixedly connected to the bottom of the support frame 1. Expansion rods 42 are fixedly connected to both the front and back of the support block 41.

[0035] During the actual operation process, when this device is in use, first place the pipe truss to be welded on the top of the support frame 1, so that the cylindrical side of the pipe truss is located inside the clamping block 38 to achieve the purpose of preliminary support. Immediately afterwards, the motor 302 can be started to work. The output end of the motor 302 can drive the worm 31 to rotate. The worm 31 drives the support rod 33 to rotate through the transmission of the worm gear 32. The support rod 33 can drive the gear 34 to rotate. Since the gear 34 and the rack 35 are in a meshing relationship, the gear 34 will push the rack 35 to move. The rack 35 can drive the slider one 39 to slide and be limited within the inner wall of the fixed slot one 301. At the same time, the rack 35 can drive the clamping block 38 to move through the fixed block 36 and the connecting rod 37, so that the clamping block 38 can clamp and limit the cylindrical side of the pipe truss. Thus, the stability of the pipe truss can be ensured during the welding process, further improving the stability of the pipe truss processing. At the same time, it is ensured that the pipe truss will not easily shift or shake, reducing the risk during the processing of the pipe truss.

[0036] Start the telescopic rod 42 to work, so that the telescopic rod 42 can drive the connecting block 43 to move. At the same time, the connecting block 43 can drive the fixed box 2 to move. At the same time, the fixed box 2 can drive the slider two 44 to slide and be limited within the inner wall of the fixed slot two 46. Thus, the position adjustment of the clamping block 38 can be realized, facilitating the adjustment of the device to be applicable to the processing of pipe trusses of different sizes, further improving the flexibility during the use of the device and enhancing the practicality of the device.
