[0024] In the above technical scheme, it is taken into account that a common traction machine needs two variable frequency motors to drive, resulting in unnecessary waste of resources. In order to solve such problems, the specific operations are as follows: by setting a linkage component, the two rotating rods 6 are rotated at the same time, thereby driving the two traction belts 7 to rotate. In this way, only one variable frequency motor is needed to drive the two rotating rods 6 and the two traction belts 7, avoiding the energy waste caused by the two motors working at the same time. By setting an adjustment component, the distance between the first mounting frame 1 and the second mounting frame 5 can be controlled, thereby adjusting the distance between the two traction belts 7.

[0026] In the above technical scheme, it is taken into account that a common traction machine needs two variable frequency motors to drive, resulting in unnecessary waste of resources. In order to solve such problems, the specific operations are as follows: by setting a bevel gear 17 and a ring gear 18, the two bevel gears 17 are staggered in upper and lower positions, and the teeth of the two bevel gears 17 are opposite. The ring gear 18 is composed of two groups of ring gears 18 merged together, the outer bevel gear 17 is meshed with the outer ring gear 18, and the inner bevel gear 17 is meshed with the inner ring gear 18, so that the two bevel gears rotate in opposite directions, thereby driving the two traction belts 7 to rotate in opposite directions, so as to achieve the effect of traction of the pipe fittings.

[0030] Working principle: When in use, the device is moved to the working area by the roller 13, and then the hydraulic cylinder 12 is controlled to extend and retract to drive the first mounting frame 1 and the second mounting frame 5 to approach each other, so that the two traction belts 7 are close to each other, thereby adjusting the distance between the traction belts 7 and the corresponding pipe size. The pipe is placed in the middle of the two traction belts 7, and then the motor 8 is started to drive one of the rotating rods 6 to rotate, thereby driving the bevel gear 17 and the ring gear 18 to rotate, and then driving the traction belt 7 to rotate, and the middle pipe is pulled.
