The pushing member 5 comprises a moving frame 51, the moving frame 51 is a strip-shaped plate with two raised ends and the middle arranged in the bracket 4, and the two raised ends are positioned outside the bracket 4 and hinged with the secondary transmission rod 32. Wherein, the bracket 4 is provided with a chute 6 in an inclined way, and the plate reciprocates along the chute 6. Push plates 52 are arranged on the plate at equal intervals (the push plates and the plate are movably connected through bolts), and the push plates 52 move synchronously along with the plate.

Need tentatively carry out the centre gripping with the slight compression of spring earlier through push pedal 52 in this scheme, it is concrete, upper and lower both sides mirror image arranges second grade dowel 32, moving frame 51 and push pedal 52, is the little opening form in order to stabilize the centre gripping relatively at the input spring in-process in the big inboard in the outside between two plates about simultaneously.

Furthermore, the upper plate and the lower plate drive the spring clamped between the upper plate and the lower plate to move synchronously in the horizontal direction. It should be noted that during the mounting process, slight deviations of several millimeters in size (slight deviations inherent in production) are likely to occur, resulting in slight deflections of the longitudinal spring bottom and top coils, which affects yield. Therefore, the scheme is that the plurality of mounting holes 12 are arranged in the vertical direction of the linkage plate 33 for size adjustment, and sufficient allowance is provided, so that the lengths of the upper, lower, left and right secondary transfer rods 32 which are finally mounted are kept absolutely uniform, the process of pushing the spring is always kept balanced, the string of the spring is more stable, and the production efficiency is higher.
