During ring block rotates, the bottom for pushing and pulling block is discontiguous with ring block, and there will be no frictional force, can extend annular
Block and the service life for pushing and pulling block reduce maintenance rate, reduce energy consumption.Meanwhile in the right side of locating ring and circular orientation block
Magnetosphere is set on left side, in this way during push-and-pull block is moved to the left and moves right, for being moved to the left, normally
In the case of, pushing and pulling between block and the inner wall of annular groove has spacing, that is, does not contact, and when being moved to the left, pushes and pulls the left side of block
Face is contacted with the inner wall of annular groove, then pushes and pulls block and ring block is pushed to be moved to the left, that is, push transmission gear to moving to left
Dynamic to be engaged with first gear, after the stroke that push-and-pull cylinder output shaft stretches out reaches, transmission gear and first gear are also
Contact is not engaged, is pushed and pulled block at this time and is contacted with the inner wall of annular groove, then due to magnetospheric presence, magnetosphere on locating ring
Suction directly transmission gear and bindiny mechanism can be adsorbed to the left, so that protrusion is snapped onto in card slot.In bindiny mechanism and transmission
During gear is moved to the left by magnetosphere absorption, push-and-pull block does not move, and pushes and pulls block in this way with respect to annular groove
It moves right, the middle part of annular groove can be in by pushing and pulling block in this way, that is, the inner wall of push-and-pull block and annular groove does not connect
It touches, is not contact friction with push-and-pull block in this way during ring block rotates, ring block and push-and-pull block can be extended in this way
Service life, reduce resistance, reduce energy consumption, reduce noise.
