Detailed Description
Example (b): the utility model provides a reticulation formula screw 4 extractor, includes extractor head 1 and action bars portion 2, 2 integrated into one piece of action bars portion are in 1 one end of extractor head, and the terminal surface of the 1 other end of extractor head just can closely laminate the surface of 4 heads of one-way screw, are equipped with a plurality of bumps 3 on the terminal surface of the 1 other end of extractor head, and these a plurality of bumps 3 just can interlock with the surface of the head of screw 4. During the use, hug closely the head of one-way screw 4 with extractor head 1, bump 3 on the extractor head 1 then is fixed a position with the head interlock of one-way screw 4, at this moment, rotate extractor head 1 through operating rod portion 2, then one-way screw 4 is along with extractor head 1 synchronous revolution, realize the effect that 4 antiport of one-way screw was dismantled, screw 4 extractor simple structure of this structure, and convenient operation can realize 4 quick dismantlements of one-way screw, and simultaneously, the damage to 4 heads of one-way screw has been avoided, 4 can also used repeatedly of one-way screw.
The plurality of salient points 3 on the end face of the other end of the extractor head part 1 are all triangular sharp structures. The triangular spine structure realizes the tight occlusion with the head of the one-way screw 4, and the slipping phenomenon when the one-way screw 4 rotates reversely is avoided.
The plurality of salient points 3 on the end surface of the other end of the extractor head part 1 are distributed in a reticulate pattern shape.
The shape of the extractor head 1 is matched with the inner groove structure of the head of the one-way screw 4, the extractor head 1 can be just inserted into the inner groove structure of the head of the one-way screw 4, and the side wall of the extractor head 1 is stopped on the side wall of the inner groove structure of the head of the one-way screw 4. When the one-way screw 4 is disassembled, the extractor head 1 is inserted into the inner groove structure of the head of the one-way screw 4, so that the limitation of the extractor head 1 is realized.
The edge of the head part 1 of the extractor is provided with a sharp cutting edge structure 5, and the sharp cutting edge structure 5 can be just embedded on the anti-dismantling inclined side wall of the groove structure in the head part of the one-way screw 4. Through forming sharp-pointed blade structure at extractor head 1 edge, through this sharp-pointed blade structure and one-way screw 4 prevent tearing open the inclined plane interlock, when avoiding extractor head 1 counter rotation with prevent tearing open the inclined plane and skid and take place relative motion, further improved extractor head 1 and one-way screw 4 head joint strength.
The extractor head 1 is an inverted Z-shaped structure formed by the fleshing structures 6 on two sides of the cylindrical structure, and cutting edges are formed at two ends of the inverted Z-shaped structure. The extractor head 1 processed by the method forms a sharp-angle-shaped cutting edge at the circumferential outer side wall and the fleshing part, the cutting edge is sharp, and the extractor head can be firmly occluded with the anti-dismantling inclined plane at the head part of the one-way screw 4.
The fleshing structures 6 on both sides of the extractor head 1 gradually decrease in depth from the other end of the extractor head 1 toward the operating rod 2. When guaranteeing 1 appearance of extractor head and 4 inner groovss structure matchings of one-way screw and having the blade, improve the bulk strength of extractor, fracture when avoiding rotatory dismantlement.
The operating rod part 2 is of a polygonal structure capable of being fixedly positioned with the electric tool.
The extractor head 1 is a T-shaped structure with one end diameter smaller than the other end diameter.
