The upper compression clamping jaw 111 and the lower compression clamping jaw 112 protrude outward at the same end thereof and are provided with a clamping mouth 113 for clamping the spring 6; and the clamping mouth 113 is internally provided with a compression cavity 114 for compressing the spring 6. The compression cavity 114 is in a shape and size suitable for the spring 6. When the compression driving source 122 drives the upper compression clamping jaw 111 and the lower compression clamping jaw 112 to move towards each other, the spring 6 can be clamped and compressed; and when the compression driving source 122 drives the upper compression clamping jaw 111 and the lower compression clamping jaw 112 to move away from each other, the upper compression clamping jaw 111 and the lower compression clamping jaw 112 can be reset, thereby preparing for clamping the spring 6 next time.

[0032] In order to enable the clamping jaw connecting sliding blocks 121 to drive the upper compression clamping jaw 111 and the lower compression clamping jaw 112 to move towards or away from each other, the compression driving source 122 is detachably provided with a sliding groove 1221 at the end thereof facing the clamping jaw connecting sliding blocks 121; the clamping jaw connecting sliding blocks 121 are in sliding connection with the sliding groove 1221; and the compression driving source 122 controls the clamping jaw connecting sliding blocks 121 to move towards or away from each other in the sliding groove 1221, thereby driving the upper compression clamping jaw 111 and the lower compression clamping jaw 112 to move towards or away from each other.
