Pilot hole described in the utility model has semicircular Long Circle for centre with the arc transition two ends, described arc transition is towards the sector gear center, thereby guide pillar when motion, there is certain headspace in pilot hole, and headspace matches with the running orbit of guide pillar, make the promotion connecting rod be not easy to damage, impact resistance is stronger.
The utility model promotion connecting rod is the integral type structure and is plastic material, makes and promotes the connecting rod cost, processes simple.
The opening of draw-in groove described in the utility model is infundibulate.Can facilitate the installation of movable spring assembly.
Draw-in groove cross section described in the utility model comprises upper wall surface and lower wall surface, and upper wall surface is provided with the arc section transition.When promoting connecting rod and pressing down, the movable spring assembly movable end withstands on arc section, thereby the setting of arc section can prevent from promoting connecting rod damage movable spring assembly when pressing down, and length can increase the service life.
Movable spring assembly described in the utility model is provided with snap fit, and snap fit and draw-in groove match.After movable spring assembly and the clamping of promotion connecting rod, snap fit can prevent that in motion process, movable spring assembly breaks away from and lost efficacy with the promotion connecting rod.
Be provided with reinforcement between the upper and lower of described promotion connecting rod described in the utility model.The setting of reinforcement can increase the intensity that promotes con-rod only integral body.
The perforate direction of the pilot hole of promotion connecting rod described in the utility model is vertical with the perforate direction of draw-in groove.
The utility model compared with prior art, has the following advantages and effect: simple in structure, reasonable in design, easy for installation, and long service life, cost of manufacture is low, stable performance, contact is reliable.
