Abstract
The present invention relates to a kind of chalk sleeve, more particularly to a kind of automation chalk sleeve.Including housing, the fixed cover of upper end clamping chalk lower end threaded connection screw rod is provided with housing, it is characterised in that：The opening of the housing is provided with range sensor, and the screw rod is installed on the power control unit of connection range sensor.The present invention realizes the automation regulation of chalk extension elongation by setting range sensor and power control unit.
Description
Technical field
The present invention relates to a kind of chalk sleeve, more particularly to a kind of automation chalk sleeve.
Background technology
Chalk sleeve species in the market is a lot, can protect finger well, while is connected through a screw thread one kind
Mechanism can also adjust the length of chalk stretching.But its mode adjusted manually wastes time and energy, also inevitable during regulation
Want upper chalk dust in one's hands.
The content of the invention
The present invention is in order to make up the deficiencies in the prior art, there is provided one kind automation chalk sleeve.
The present invention is achieved through the following technical solutions：
One kind automates chalk sleeve, including housing, and the fixation of upper end clamping chalk lower end threaded connection screw rod is provided with housing
Set, it is characterised in that：The opening of the housing is provided with range sensor, and connection Distance-sensing is fixedly mounted under the screw rod
The power control unit of device.
Guide groove is provided with the housing, can prevent fixed cover from circumferentially rotating.
With being write on blackboard, stretching out the chalk length of chalk sleeve can slowly shorten, that is, chalk sleeve and seriticker
Distance shortens, and when reaching certain value, range sensor can trigger power control unit so that screw rod rotates, before driving fixed cover
Move, chalk stretches out chalk sleeve opening also with more.
The present invention by setting range sensor and power control unit, adjust by the automation for realizing chalk extension elongation
Section.
