Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides an embodiment: a holder for fixing taper shank drill bit specially, including first holder 1 and lag 12, logical groove 17 and circular slot 2 have been seted up to 1 outer wall inside of first holder, the inside of circular slot 2 is embedded to have spring 3, the one end and the fixed welding of inserted block 11 of spring 3, the other end of spring 3 and the fixed welding of inner wall of circular slot 2, the elastic construction is constituteed with spring 3 to inserted block 11, when the drill bit drills, the drill bit moves, thereby make lag 12 take place the extrusion, lag 12 extrudees spring 3, thereby make lag 12 indentation circular slot 2 and the inside that leads to groove 17, make the drill bit when drilling, can avoid iron fillings to scatter everywhere, make personnel's factor of safety better, it is more convenient to use.

The inner wall fixed mounting of first holder 1 has baffle 4, and the inner wall of baffle 4 is provided with frustum through hole 5, and the inner wall of baffle 4 is the inclined plane, the diameter of frustum through hole 5 inner wall reduces from a left side to the right side in proper order, can make the outer wall of frustum through hole 5 laminating more and taper shank drill bit to make the fixed effect of taper shank drill bit better, it is more convenient to use.

The right-hand member movable mounting of first holder 1 has second holder 6, the right-hand member fixed mounting of first holder 1 has fixed block 8, slot 7 has been seted up to the left wall of second holder 6, fixed slot 18 has been seted up to the inside of second holder 6, the shape of fixed block 8 is "L" type, slot 7 is vertical groove, fixed slot 18 is the transverse groove, and fixed slot 18 communicates with the inside right-hand member end of slot 7 mutually, can make fixed block 8 insert and rotate behind slot 7, can't outwards extract after rotating the inside of fixed slot 18, thereby fix, high durability and convenient use. Slot 7's inner wall width equals with fixed block 8's outer wall width, slot 7 constitutes embedded structure with fixed block 8, the height of fixed block 8 outer wall equals with the height of fixed slot 18 inner wall, fixed block 8 constitutes the rotary type structure with fixed slot 18, embed fixed block 8 into slot 7's inside, when fixed block 8 inserts the right-hand member of establishing to slot 7, rotate first holder 1, thereby make first holder 1 drive fixed block 8 and rotate, make fixed block 8 rotate to fixed slot 18's inner wall and fix, when second holder 6 takes place to rotate, drive fixed block 8 and rotate to the direction of fixed slot 18 inner wall through inertia, thereby make fixed effect better, and it is more convenient to use.

The key type hole 9 has been seted up to the left wall central point department of second holder 6, the inner wall fixed mounting in key type hole 9 has wave piece 10, wave piece 10 can increase the frictional force with the afterbody of taper shank drill bit, the afterbody of taper shank drill bit can be laminated more to key type hole 9, it is more firm to make the taper shank drill bit fixed, the result of use is better, lag 12 right-hand member fixed mounting has inserted block 11, rotary groove 13 has been seted up to the left end of lag 12, the inner wall of rotary groove 13 is connected with rotary block 14, the inner wall diameter of rotary groove 13 equals with the outer wall diameter size of rotary block 14, rotary block 14 and rotary groove 13 constitute the rotary type structure, make extrusion cover 15 fix when laminating drilling four weeks, lag 12 rotates and drives rotary block 14 and rotates at the inner wall of rotary groove 13, the pivoted condition has been avoided extrusion cover 15 to take place, around having influenced drilling, high durability and convenient use, the accuracy of drilling obtains improving.

The left end fixed mounting who changes piece 14 has extrusion cover 15, and the outer wall left end fixed mounting who extrudes cover 15 has rubber strip 16, will extrude cover 15 and put in the place that needs drilling, and rubber strip 16 is laminated around drilling, has increased rubber strip 16 and drilling frictional force all around, makes the stability of drill bit obtain promoting, takes place the phenomenon of skidding when having avoided the drill bit to drill to the accuracy when making the drill bit drill hole is better, and it is more convenient to use.

The working principle is as follows: during the use, with the inside of fixed block 8 embedding slot 7, when the right-hand member of fixed block 8 to slot 7, rotate first holder 1, make first holder 1 drive fixed block 8 and rotate, thereby make fixed block 8 rotate and fix to the inner wall of fixed slot 18, further make first holder 1 can't break away from second holder 6, insert the inside of frustum through hole 5 with the tail end of drill bit, the tail cone of drill bit imbeds the inside of key type hole 9, increase the frictional force with the drill bit through wave piece 10, thereby make the drill bit fixed more firm, when the drill bit rotates, second holder 6 takes place to rotate, thereby make first holder 1 take place to rotate, first holder 1 drives lag 12 and takes place to rotate.

When the drill bit need drill, place the place at needs drilling with extrusion cover 15, extrusion cover 15 extrudees rubber strip 16, thereby make rubber strip 16 laminate around drilling, during drilling, extrusion cover 15 extrudees lag 12, lag 12 extrudees spring 3, thereby make lag 12 carry out the indentation to the inside of circular slot 2, make the drill bit expose and carry out drilling work, the condition that the iron class bits foam when having avoided drilling scatters, cause the injury to the human body, it is more convenient to use, safety factor is better, rubber strip 16 can avoid the condition that the drill bit takes place to skid, thereby influence the accuracy of drilling, make the accuracy of drill bit drilling better, it is more convenient to use.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
