[0025] In this embodiment, the motor 303 drives the active transmission wheel 304 and the driven transmission wheel 305 to rotate, which in turn causes the first screw 301 to rotate, drives the cross bar 307 to move and drives the upper pressure plate 5 to move, so that the distance between the upper pressure plate 5 and the lower pressure plate 4 is adjusted, and different specifications of welding pipes can be clamped and fixed, thereby improving the practicality of the equipment.

[0026] It should be noted that the cross-section of the bracket 2 is L-shaped, and a through hole is provided at the top of the bracket 2. The top of the first screw 301 passes through the through hole and is rotatably connected thereto, so as to facilitate the placement of the active transmission wheel 304 and the driven transmission wheel 305.

[0029] The working principle of the above embodiment is:

[0030] First, turn on the motor 303 to drive the first screw rod 301 on the left and the active transmission wheel 304 to rotate. At this time, the active transmission wheel 304 drives the driven transmission wheel 305 to rotate through the transmission belt 306, thereby causing the first screw rod 301 on the right to rotate accordingly. Then the slider 302 located on the outer surface of the first screw rod 301 also moves, thereby driving the cross bar 307 located between the two sliders 302 to move. Then the second screw rod 309 moves, driving the upper pressure plate 5 fixed thereto to move accordingly, and at the same time The slide bar 313 fixed to the upper pressure plate 5 will move along the slide rail 312 to ensure that the center of the upper pressure plate 5 and the center of the lower pressure plate 4 are always on the same vertical line, which is convenient for better fixing the welding pipe. When the position between the upper pressure plate 5 and the lower pressure plate 4 is adjusted to an appropriate distance, the motor 303 is turned off. At this time, the spring 311 abutting between the upper pressure plate 5 and the cross bar 307 will be subjected to elastic potential energy, which can play a certain buffering role, preventing damage to the upper pressure plate 5, the lower pressure plate 4 and the welding pipe, protecting the equipment to a certain extent, and reducing the cost of use.
