Further, above-mentioned hand-held overcoat rear end is provided with threaded cap, and the threaded cap inner face is provided with boss, the spring
Overhead is between boss and the endoporus of sliding inner sleeve.
Further, above-mentioned hand-held outer putting is provided with groove long, and the sliding inner sleeve is provided with can be slided in groove long
Position-limitting pin.
Further, above-mentioned wedge point is isosceles triangle flat ironware, and the flange on wedge point is perpendicular with it,
And section is the circular arc for cutting off minor arc.
Further, above-mentioned hand-held overcoat end face is provided with the flange to be conducive to being clashed into flange.
Further, the maximum load of above-mentioned spring is 2 kilograms.
The method of work of the utility model plug-in type wedge point withdrawing drill bit mechanism, the plug-in type wedge point withdrawing drill bit
Mechanism includes hand-held overcoat and the sliding inner sleeve being located in hand-held outer sleeve body, and bullet is provided between the hand-held overcoat and sliding inner sleeve
Spring, the sliding inner sleeve end is provided with wedge point, and the wedge point is provided near the end of sliding inner sleeve can be with hand-held overcoat end
The flange that face is clashed into；During work, one hand of operator grips hand-held overcoat, the drill bit on a hand gripping drilling machine, by wedge point
Insert in the elongated hole of drill press spindle, now firmly hand-held overcoat exerts oneself to impact toward the tip of wedge point, hand-held overcoat end is hit
Flange is hit, wedge point is constantly impacted the upper end of drill bit in elongated hole, drill bit can back and forth extruded several times.
In use, position-limitting pin is inserted with sliding inner sleeve, is slided with groove long；It is spacing when not using
Pin is extracted, and hand-held overcoat is separated with sliding inner sleeve.
One hand of operator grips hand-held overcoat when the utility model is used, and the drill bit on a hand gripping drilling machine will be oblique
In the elongated hole of iron point insertion drill press spindle, now firmly hand-held overcoat is exerted oneself to impact toward the tip of wedge point, hand-held overcoat end
Portion's hits lip, makes wedge point constantly impact the upper end of drill bit in elongated hole, can back and forth extrude drill bit several times；Application method side
Just, safety, efficiency high.
