Every two springs of setting, in being equipped with connecting shaft in spring, which is fixedly connected with the press component, the connecting shaft other end
It is connected with bearing bracket stand, and two connecting shafts are individually fixed in bearing bracket stand both ends, bearing is equipped among bearing bracket stand.
The bearing periphery is equipped with "U" type groove.
The pedestal corresponds to the press component accommodating cavity and into silk switch drive accommodating cavity, is equipped with fixed plate.
The press component includes pressing piece, is equipped with spring steel plate in pressing piece one end, is equipped with spiral shell in spring steel plate both ends
Bolt, the bolt are fixedly connected with the connecting shaft, and are moved in press component accommodating cavity.
The corresponding bearing, is equipped with through-hole in the middle part of the pedestal, in being equipped with motor gear in the through-hole, the motor gear with
Driving motor is connected.
The through-hole and between silk switch drive accommodating cavity, is equipped with into silk channel, distinguishes in into silk channel both ends
Equipped with inlet port and outlet port；The motor gear and bearing are located at into silk channel two sides.
The beneficial effects of the utility model are: 1, bilateral spring forms one symmetrically laterally on the both sides of groove bearing
Power, so that the cross force size and Orientation of groove bearing and gear has good stability；2, only with pressing when being installed into thread
Button puts in silk, time saving and energy saving；3, entire extrusion mechanism has shell sealing, to internal structures such as bearing and gears
There is good dust-proof effect, while being reserved with the visual windows observed into silk situation, can more preferably grasp in real time into silk situation.
Detailed description of the invention
