Among them, the positive and negative thread ball screw 502 is completely located inside the transmission disc 3, and the limit sliding groove 503 penetrates the side wall of the transmission disc 3. The mid-perpendicular plane of the positive and negative thread ball screw 502 coincides with the mid-perpendicular plane of the transmission disc 3.

The longitudinal section of the limit block 505 matches the longitudinal section of the limit sliding groove 503. By sliding the limit block 505 inside the limit sliding groove 503, the function of limiting the movable seat 504 is realized.

[0033] First, select a suitable winding cylinder 4 according to the size of the spring to be wound, and then start the servo motor 501, so that the servo motor 501 drives the positive and negative thread ball screw 502 to rotate, thereby driving the movable seat 504 and the mounting rod 507 to move towards each other until the distance between the two is adapted to the winding cylinder 4.
