Abstract

The utility model discloses a drill demounting tool of a silicon material polisher. The drill demounting tool of the silicon material polisher comprises a center shaft and a jaw. A pointed cone is arranged at the front end of the center shaft. The back end of the jaw is fixed at the back portion of the center shaft, and the front end of the jaw contracts and expands in the radial direction along the center shaft. The drill demounting tool of the silicon material polisher has the advantages of being simple in structure, and convenient to use. The pointed cone at the front end of the center shaft is hit in the tail portion of the drill to fix, then the jaw grasps a drill main body, the whole demounting tool is rotated, and then periphery of the drill is stressed, so that the drill can be pulled out and be easily screwed out.

Description

A kind of awl extracting tool of silicon material sander

Technical field

The utility model relates to a kind of extracting tool, particularly a kind of awl extracting tool of silicon material sander.

Background technology

In monocrystalline pole growth course, often will be with sander the polish impurity and the oxide on silicon material surface, cause the awl of sander the inside often to need to change, and the permanent back awl that uses is stuck in sander, sometimes twist not get off and to strike with hammer, whole awl is struck bad easily like this, both wasted the time, increased cost again.

The utility model content

The utility model purpose: at the problems referred to above, the purpose of this utility model provides a kind of extracting tool of awl of the silicon material sander of conveniently back-outing.

Technical scheme: a kind of awl extracting tool of silicon material sander, comprise central shaft, cleft hand, described central shaft front end is a pointed cone, described cleft hand rear end is fixed on described central shaft rear portion, and the described central shaft radial contraction of described cleft hand front end edge, expansion.

Described central shaft rear end offers handle hole.

The quantity of described cleft hand is at least two, and along the circumferential uniform setting of described central shaft.

Beneficial effect: compared with prior art, the utility model has the advantages that simple in structure, easy to use, throwing the pointed cone of central shaft front end into the awl afterbody fixes, catch the awl main body by cleft hand again, rotate whole extracting tool, make awl stressed all around, can extract awl, easily awl is back-outed.

Description of drawings

Fig. 2 is the utility model user mode schematic diagram.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.

As shown in Figure 1, a kind of awl extracting tool of silicon material sander, comprise central shaft 1, cleft hand 2, central shaft 1 front end is a pointed cone 3, the quantity of cleft hand 2 is at least two, cleft hand 2 is fixed on central shaft 1 rear portion along central shaft 1 circumferential uniform setting with cleft hand 2 rear ends, like this cleft hand 2 front ends can shrink in the radial direction, expanding at central shaft 1.Central shaft 1 rear end offers handle hole 4.

As shown in Figure 2, during use, throw the pointed cone 3 of central shaft 1 front end into awl 5 afterbodys and fix, shrink by cleft hand 2 and catch awl 5 main bodys, with handle 6 handle hole 4 of packing into, turning handle 6 rotates whole extracting tool, stressed around the awl 5, can extract awl 5, awl 5 is back-outed.
