Detailed description of the invention

Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example is only for explainingThe utility model, is not intended to limit scope of the present utility model.

As shown in Fig. 1～2: a kind of get excellent device through skin, comprise the first pincers rod 1 and the second pincers rod 2, described theThere is the sharp mouth concaving on the top of one pincers rod 2, and the front end of described the second pincers rod 2 is tack, described the first pincersThe front end of rod 1 and described the second pincers rod 2 form one can clamp screws connecting rod clamping part, and instituteState the first pincers rod 1 and be longer than described the second pincers rod 2, described the first pincers rod 1 and described the second pincers rod 2 from front end toEnd is del, and end is connected with handlebar 5, and there is a cavity 12 described handlebar 5 inside,Describedly get on excellent device and be set with sleeve 3 through skin, on described sleeve 3, have hole clipping 9; , described cavity 12 is positioned at instituteState the below of the end of the first pincers rod 1 and described the second pincers rod 2, the top of handle 13, described sleeve 3Length can be entangled the cavity 12 in described handlebar 5;

Described handlebar 5 is integrative-structures with described handle 13;

The cavity 12 of described handlebar 5 inside is provided with fixture 6, described fixture 6 by round bar 7,Triangle buckle 10 and elastic device 4 form, and described triangle buckle 8 is by elastic device 4 and described handleThe interior handle wall of bar 5 cavity 12 is connected, and described triangle buckle B end 11 is threaded connection with described round bar 7,Described round bar 7 not link and triangle buckle A end 10 protrudes from described handlebar 5, described triangle buckle AEnd 10 fastens with the hole clipping 9 on described sleeve 3;

Further, the diameter that inserts the hole of described handlebar 5 for described round bar 7 is greater than described round bar 7Diameter is more prone to clean to the bloodstain in cavity in the time backing out round bar 7;

Further, described round bar 7 not link be provided with anti-slip veins;

Further, described handle 13 curve of hand-type that can be designed to fit;
