Abstract
An automatic chalk sleeve capable of keeping chalk unbroken at least comprises a rod, a spring, soft rubber, a fixator, a chalk head, a lifting rod, a switch and magnetic paper. The rod is arranged on the outer surface of the fixator and embedded into the top end of the spring arranged on the side wall of the fixator; the side end of the spring is connected with the rod; the soft rubber is arranged at the end of the fixator and tightly connected with the fixator; the chalk head is located at the upper end of the fixator, and the bottom of the chalk head is tightly connected with the lifting rod; the lifting rod is arranged in the fixator and connected with the switch in a matched mode; the switch is arranged on the outer surface of the fixator; and the magnetic paper is pasted to the bottom end of the fixator and tightly connected with the fixator. By adoption of the structure, the chalk can be kept unbroken, a hand does not need to be washed anymore after gripping the chalk, the chalk can be automatically ejected out, using is more convenient, and the automatic chalk sleeve is suitable for using and popularization.
Description
Technical field
The present invention relates to educational aid applied technical field, especially a kind of have the chalk sleeve that automatically will not break.
Background technology
With the continuous improvement of living standard, the moral level of society, know-how, life requirement, job requirement etc. are all
Change constantly, and chalk is the instrument teaching knowledge, chalk is a kind of can be adsorbed on object by what gypsum was made
Material, an instrument very important in teaching, but when the shorter very difficult grasp of chalk is write firmly, due to unbalance stress
Or stress is inconsistent causes chalk to easily snap off, it is also easy to produce dust, the approach that chalk dust enters lung is by upper respiratory tract bag
Include nose, pharynx, bronchus, in this course, lung and the upper respiratory tract are worked the mischief；The granule dust floating in the air also can
Fall teacher's hair, on the face with neck on, have stimulation to skin membrane, because the environment survived of human body skin is faintly acid
Environment, so destroys the basic living environment of skin under dust alkalescence effect, affects for all the foregoing reasons and disturb
Teacher's normal work and life, because teaching profession's disease that dust leads to also gets more and more, dimension, propose for the problems referred to above
A kind of have the chalk sleeve that automatically will not break.
Content of the invention
For the problems referred to above, the present invention is intended to provide one kind can ensure that chalk constantly, and hold after chalk can be without
Washing one's hands, can be with automatic chalk ejection, easy to use has the chalk sleeve that automatically will not break.
For realizing this technical purpose, the solution of the present invention is：A kind of have the chalk sleeve that automatically will not break, and at least includes
Include bar, spring, soft rubber, fixator, chalk end, elevating lever, switch and suction iron paper；Described bar is arranged on the outer surface of fixator
And it is embedded in the end being arranged on spring on the wall of fixator side；The side of described spring is connected with bar；Described soft rubber is arranged on
The end of fixator, and soft rubber is closely connected with fixator；Described chalk end is located at the upper end of fixator, and chalk end
Bottom be closely connected with elevating lever；Described elevating lever is arranged on the inside of fixator and is connected with switch；Described switch
It is arranged on the outer surface of fixator；Described suction iron paper is pasted onto the bottom of fixator and is closely connected with fixator.
Optimisation technique scheme as the present invention：The head end that described soft rubber is sleeved on fixator is detachable；Described chalk
Controlled by the spring in bar and install, and bar is projection cube structure；Described suction iron paper is connected with fixator end, and inhaling iron paper can be changed to
Other adsorption structure.
Compared with prior art, the invention has the beneficial effects as follows：This has the chalk within the chalk sleeve that automatically will not break
Controlled by spring in bar and install, and bar is projection cube structure, inhale iron paper and be connected with fixator end, make chalk in use more
Plus convenient and convenient when not using place, inhale iron paper and can be changed to other adsorption structure, make chalk can be used for different occasions,
This chalk sleeve can reduce the injury that directly contact chalk can cause to body and solving and exert oneself uneven to produce more dust
Problem,
Brief description
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the fixator external connection schematic diagram of the present invention；
Wherein：1st, include bar, 2, spring, 3, soft rubber, 4, fixator, 5, chalk end, 6, elevating lever, 7, switch, 8, inhale
Iron paper.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
