As preferred：The ball is located at the outside of compression spring.
As preferred：The positioning hole is evenly distributed on chute.
As preferred：The quantity of the positioning hole is 3~9.
The beneficial effects of the utility model are：
1. because the top of slide offers spring eye, compression spring and ball are provided with spring eye, and lower house is interior
Side is provided with chute, and evenly distributed positioning hole is offered on chute so that pusher can be according to ball when sliding
Coordinated with positioning hole, so as to which different stalls be adjusted, there is the advantages of accurate and scope of transferring the files is wide.
2. the setting of slide bottom slide opening, and slide bar is arranged with slide opening so that pusher can be slided on slide bar
It is dynamic, traditional pusher is changed directly in the enterprising line slip of resistor disc so that is worn small during slip, and is slided steady, sliding
Dynamic soft handle, it is less prone to and loosens and cause the situation for adjusting electric current and voltage inaccuracy.
3. due to opening up for blind hole, and drier is filled with blind hole so that showing for humidity is less prone to inside potentiometer
As improving service life to a certain extent.
4. because slide bar outer surface is adhesive with graphite linings so that pusher can have good profit when being slided on slide bar
Sliding effect.
