The assembling process not only has high production intensity of the workers, but also has low production efficiency. At present, some compression equipment is used to replace the manual compression, that is, after the slider and the spring at one end are manually assembled, the slider and the spring are placed into the compression equipment, the slider is pulled back by the compression equipment to compress the spring, so that the slider and the spring at the other end can be manually placed.
