[0002] Flexible shafts are shafts with low rigidity and high elasticity, capable of free bending and transmission. They are used to connect two shafts that are not on the same axis, not in the same direction, or have relative motion to transmit rotational motion and torque, flexibly transmitting rotational motion and torque to any position. The processing of flexible shafts requires various equipment to complete processes such as cutting, chamfering, deburring, and de-linting, all of which require the flexible shaft to roll around its axis. However, most flexible shaft processing equipment can only drive a single flexible shaft to roll, making it difficult to handle the rolling of multiple flexible shafts simultaneously, reducing processing efficiency and failing to meet the needs of mass production.

The mounting plate 31 has four spaced mounting strips 9 arranged along a straight line at its bottom. Each second transmission wheel 34 is rotatably connected to a mounting strip 9. The gap between two adjacent mounting strips 9 allows the flexible shaft 1 to pass through the upper and lower opposing first transmission wheels 33 and second transmission wheels 34, which are staggered. The transmission belt 32 is S-shaped and passes from top to bottom around the driving wheel 35, each first transmission wheel 33, each second transmission wheel 34, and the driven wheel 36, so that the transmission belt 32 on each second transmission wheel 34 forms four spaced U-shaped structures 6.
