One end is provided with screw corresponding with screw rod, and the slide block is connected by screw with screw rod, and the screw rod is remote
One end from screw is connected with base, and the slide block is provided with chalk sleeve away from the side of base, described outer
Sweep-up pipe is connected with shell, air-introduced machine is provided with the inner chamber of the sweep-up pipe, the sweep-up pipe away from
The side of shell is provided with installing port, and chalk ash collection box, institute have been threaded connection in the installing port
State sweep-up pipe and be provided with ventilating opening away from one end of air-introduced machine, filter is provided with ventilating opening, power supply leads to
Cross switch electrical connection air-introduced machine.
Preferably, the surface of the chalk sleeve is provided with anti-slip veins.
Preferably, the switch is embedded in case surface.
Preferably, the filter is screen pack.
Preferably, the side of the slide block is provided with chute, and the inwall of the shell is provided with and chute pair
The slide rail answered, the slide rail is located in chute.
In the present invention, user when in use, can be clamped chalk by chalk sleeve, then by base
Rotation, and then the rotation of screw rod is driven, slide block is caused along the slide rail of inside the shell by the rotation of screw rod
Square upward sliding, and then length of the chalk of chalk sleeve clamping outside shell is changed, reach and use
Person's needs length, then the switch on shell is opened, and air-introduced machine is started working, and is used in user
During, the chalk dust of generation is sucked into the chalk ash collection box of sweep-up pipe in the presence of air-introduced machine,
When user terminates to use chalk, chalk ash collection box is screwed off from the installing port of sweep-up pipe, clearly
Reason chalk ash collection box, the device can change length of the chalk outside shell, be changed by rotating base
Become the use length of chalk, the chalk dust of generation can also be collected immediately so that chalk dust will not appoint
Meaning is scattered, and reaches the effect of protection user, and the device is easy to use and environmental protection, allows user
Work is more safe and efficient.
Description of the drawings
Fig. 1 is a kind of structural representation of environmentally-friendly chalk holder proposed by the present invention.
In figure：1 shell, 2 slide blocks, 3 bases, 4 power supplys, 5 sweep-up pipes, 6 chalk ash collection boxes,
7 air-introduced machines, 8 chalk sleeves, 9 screw rods.
Specific embodiment
