Abstract
Provided is a chalk writing drum. A rotary base is arranged on a chalk drum; a fixing groove is formed in the rotary base; a fastening screw is arranged on the fixing groove; and the chalk drum is connected with the rotary base through threads. According to the chalk writing drum, by the adoption of the structure, a thread connection structure of the rotary base and the chalk drum can be effectively utilized, the rotary base and the chalk drum can move relatively by rotating the rotary base to enable chalk to stretch out and contract back, only a hand needs to hold the chalk drum during writing, direct contact between fingers and the chalk is avoided, the fingers are protected, frequent hand washing is not needed after writing, and the water resource is saved.
Description
Technical field
The present invention relates to daily living article field, particularly a kind of chalk-writing cylinder.
Background technology
Because existing chalk is all the tactile chalk that directly catches when writing, the harmful substance containing in such chalk holds
Easily finger is damaged, and be often required to after writing be rinsed with water, waste substantial amounts of water resource.Ask for solving this
A kind of topic, there is provided chalk-writing cylinder.
Content of the invention
The technical problem to be solved be provide a kind of chalk-writing cylinder, can effectively utilize rotating base with
The screw connection structure of chalk barrel, by rotating rotating base, makes to produce relative movement between rotating base and chalk barrel,
And then chalk can be extended and retracted, only need to grasp chalk barrel when writing, it is to avoid finger and chalk
Directly contact, protects finger, need not often wash one's hands simultaneously, saved water resource after writing.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of chalk-writing cylinder, on chalk barrel
It is provided with rotating base, rotating base is provided with fixing groove, fixing groove is provided with tightens screw, described chalk barrel and rotation
Base by thread connects.
Described fixing groove is provided with chalk, and chalk barrel is provided with lid.
A kind of chalk-writing cylinder that the present invention provides, by using above-mentioned structure, during use, due to rotating base with
It is screw connection structure between chalk barrel, by rotating rotating base, can make to produce phase between rotating base and chalk barrel
To movement, and then chalk can be extended and retracted, when writing, only need to grasp chalk barrel, it is to avoid finger
With the directly contact of chalk, protect finger, need not often wash one's hands after writing simultaneously, save water resource.
Brief description
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is the overall structure diagram of the present invention.
In figure：Lid 1, chalk 2, tighten screw 3, rotating base 4, chalk barrel 5, fixing groove 6.
Specific embodiment
In Fig. 1, a kind of chalk-writing cylinder, chalk barrel 5 is provided with rotating base 4, and rotating base 4 is provided with solid
Determine groove 6, fixing groove 6 is provided with tightens screw 3, and described chalk barrel 5 and rotating base 4 are threaded connection.By
This structure, during use, due to being screw connection structure between rotating base and chalk barrel, by rotating rotating base,
Can make to produce relative movement between rotating base and chalk barrel, and then chalk can be extended and retracted, only need when writing
Grasp chalk barrel, it is to avoid finger and the directly contact of chalk, protect finger, need not be through after writing simultaneously
Often wash one's hands, saved water resource.
Described fixing groove 6 is provided with chalk 2, and chalk barrel 5 is provided with lid 1.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as the restriction for the present invention, this
The technical scheme that bright protection domain should be recorded with claim, in the technical scheme recorded including claim, technology is special
The equivalents levied are protection domain.I.e. equivalent within this range is improved, also in the protection model of the present invention
Within enclosing.
