The multifunctional automatic chalk is provided with a chalk propping device, so that the chalks are more convenient and fuller to use, resources are saved, the phenomenon that the chalks are directly held with hands is avoided and the higher sanitation is obtained; and in addition, the chalk clip with scales and the chalk brush are arranged on the chalk rod, so that users' various demands can be met synchronously.

Description

A kind of automatic chalk of using more

Technical field

The utility model relates to the teaching aid field, is specifically related to a kind of automatic chalk of using more.

Background technology

In the process of teaching, still use hand directly to hold chalk when people use chalk mostly and write, and chalk very easily makes chalk dust be bonded on hand in writing process, makes finger skin become coarse.And when we use chalk at the beginning, often use inconvenience because chalk is long, break into several sections off with the fingers and thumb after, have more than is neededly how long can be difficult for taking and hold and arbitrarily abandon because of writing surplus chalk head again, thereby cause waste.We often when writing with chalk, need wipe person's handwriting timely or need and measure some length, distance etc. in the process of teaching in addition, and taking of educational aid repeatedly also brought inconvenience to teaching, loses time.

Summary of the invention

Technical problem to be solved in the utility model, be exactly at above existing in prior technology deficiency, and a kind of of proposition use automatic chalk, this automatic chalk to be provided with the chalk device for ejecting more, use to chalk is convenient, more abundant, saved resource, keep away manual-free and directly hold by chalk, health more, and penholder is provided with the scale pen clip, and chalkboard eraser can satisfy the multiple demand of user simultaneously.

The utility model scheme realizes by following technical measures:

A kind of automatic chalk of using more, comprise chalk, penholder, nib, chalkboard eraser, wherein also be provided with a magnet pen clip on the penholder, be carved with scale on the magnet pen clip, the magnet pen clip is fastened on the penholder by rotating shaft, the penholder stage casing is provided with a slider, also be provided with a chalk device for ejecting in addition in the penholder, this device is located in penholder and the nib be connected half section, this device is by spring, becket, plastic cylinder constitutes, and slider connects the base portion of plastic cylinder, and spring housing is on plastic cylinder, fixedly connected plastic cylinder base and becket, chalk is by passing in the plastic cylinder.

The penholder outside of described chalk device for ejecting part is provided with anti-skidding line in addition.

The lower end of described plastic cylinder is divided into two plastic sheets, and becket is enclosed within on two plastic sheets.

Described chalkboard eraser is located at the penholder rear end.

The useful technique effect that the utility model brings is: this automatic chalk is provided with the chalk device for ejecting, and chalk can eject one section at any time as required, and is convenient to the use of chalk, more abundant, saved resource; Keep away manual-free and directly hold by chalk, more health; Penholder is provided with scale magnet pen clip, and chalkboard eraser can satisfy the multiple demand of user simultaneously, and can be adsorbed on the iron frame of blackboard convenient picking and placeing with this automatic chalk when not using; The penholder lower end is provided with anti-skidding line, slip phenomenon occurs after can avoiding the user to hold a pen for a long time.

This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
