Corroded by lime, health is impacted；In addition, teacher is when carrying out writing on the blackboard, it is possible to it is firmly excessive, chalk can be broken
It is disconnected, writing on the blackboard is influenceed, it is very inconvenient.
Utility model content
The utility model is in order to solve weak point of the prior art, there is provided it is a kind of it is reasonable in design, can prevent
Hand directly contacts with chalk and prevents the chalk clamp that finger breaks chalk in writing process.
In order to solve the above technical problems, the utility model adopts the following technical scheme that：Chalk clamp, including screw rod, end cap
And pen container, using the axis direction of pen container as left and right horizontal direction, end cap is threaded in the right-hand member of pen container, is offered on end cap logical
Hole, swivel nut is fixed with the left of end cap, swivel nut, through hole and pen container are coaxially set, and screw rod is located in swivel nut and through hole,
Screw rod is threadedly coupled with swivel nut, and the left end of screw rod is fixed with top plate, and the right-hand member of screw rod is fixed with handle；The inwall of pen container is consolidated
Surely resilient sleeve is provided with, the thickness right-to-left of resilient sleeve increases successively.
The right part of pen container is provided with external screw thread, is provided with internal thread on the inside of end cap, end cap passes through internal thread and the outer spiral shell of pen container
Line connects.
Sealing ring is provided between the left end and screw rod of swivel nut.
Using above-mentioned technical proposal, when using the utility model, opening end cap is screwed first, chalk is plugged in elasticity
In set, end cap is then reinstalled in the right-hand member of pen container, by rotary handle, screw rod is rotated in swivel nut, final screw rod
It is moved to the left, the Roof of screw rod left end is pressed in one end of chalk, and with the rotation of handle, top plate releases chalk, final powder
The left end of pen container is stretched out in one end of pen, you can is write with holding pen container；Because existing chalk is all cone structure, and this
The thickness of the resilient sleeve of utility model gradually increases, therefore during being write, chalk will not drop out out of pen container,
Resilient sleeve can grip chalk well, while chalk will not be caused to damage；Additionally preferably, the right part of pen container is provided with outer
Screw thread, end cap inner side are provided with internal thread, and end cap is attached with pen container by this engagement thread, can prevent chalk foam from falling
On screw thread, so as to influence the fitness of threaded connection, if being provided with external screw thread on the outside of end cap, internal thread is provided with the inside of pen container,
It is attached by this engagement thread, chalk foam is easy to accumulate on the internal thread of pen container, so as to influence end cap and pen container
Between screw thread coordinate；Similarly, sealing ring is provided between the left end and screw rod of swivel nut, sealing ring prevents chalk foam from entering swivel nut
It is interior, coordinate so as to influence the screw thread between swivel nut and screw rod；Teacher using the utility model when being write, the strength of finger
It is applied on pen container, chalk does not bear the gripping dynamics of finger directly, therefore chalk can be kept not broken.
In summary, the utility model is reasonable in design, and gripping is firm respectively, and teacher is utilizing present apparatus gripping powder
Pen, so as to prevent the hand of teacher to be contacted with the direct of chalk, skin is protected, and ensure that the health of teacher, and
And will not break chalk because holding great efforts, it is easy to use.
