The existing spring operating mechanism includes an integrated structure and a modular structure. The installation and positioning of the spring operating mechanism with an integrated structure is mainly guaranteed by the machining accuracy of the parts. Ensuring the machining accuracy of the parts ensures accurate assembly and positioning. However, due to the number of parts Many, cumbersome installation, inconvenient maintenance, unable to adapt to the needs of product diversification and short delivery time

The existing modular structure spring operating mechanism includes an opening unit and a closing unit. The opening unit and the closing unit are separated by a partition, and the partition is connected by a plurality of connecting rods. Since the multiple connecting rods and the partition pass through Pin hole positioning, the connection cannot guarantee consistency, the partition and the box are connected by bolts, due to the gap between the bolts and the bolt holes, accurate positioning cannot be guaranteed, when the opening unit and closing unit are installed normally, the opening unit and closing unit It will slide down due to its own weight, causing misalignment, resulting in the failure to achieve normal closing and opening locks. In addition, the parts assembled on the main shaft are also installed one by one, which is not convenient for mass production.
