Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, this utility model blunt needle buttonhole puncturing removes crust device, including handle the 1, first sheath 5 and the second sheath
6, handle 1 is cylindrical, and the two ends of handle 1 are respectively provided with crust pin 2 and tweezer 3, goes crust pin 2 and tweezer 3 can be embedded in hands respectively
The two ends of handle 1.The termination removing crust pin 2 is blunt needle shape, and removing crust pin 2 can be solid or hollow structure, and the two ends of handle 1 are the most sheathed
First sheath 5 and the second sheath 6, and the first sheath 5 and the second sheath 6 be the tubular structure of both ends open.
The two ends of handle 1 are respectively provided with the first collar 11 and the second collar 14, and the first collar 11 and the second collar 14 are used for
Limit the first sheath 5 and stroke of the second sheath 6, it is to avoid skid off from handle 1, the first sheath 5 and the second sheath 6 phase can be made simultaneously
Handle 1 is screwed.The thickness of the first collar 11 and the second collar 14 is unsuitable excessive, it is to avoid the first sheath 5 and the second sheath 6 can not
Extruding is installed on handle 1, and the cross section of the first collar 11 and the second collar 14 the most at right angles triangle, such as Fig. 1 institute
Show.Outside handle 1, first external screw thread 12 is set at the first collar 11, at the second collar 14, outside handle 1, arranges the
Three external screw threads 15, the middle part of handle 1 arranges a circle projection 17, and the both sides of protruding 17 are respectively the second external screw thread 13 and the 4th outer spiral shell
Stricture of vagina 16.
First sheath 5 arranges the first female thread 51 near the inside of the one end at the middle part of handle 1, and the first female thread 51 can be with
First external screw thread the 12, second external screw thread 13 is suitable.When first female thread 51 matches with the first external screw thread 12, go crust pin 2 complete
Entirely it is positioned at the first sheath 5, for the state before using and after use；When first female thread 51 matches with the second external screw thread 13,
Crust pin 2 is gone to be positioned at outside the first sheath 5, for the state in using.The position adjusting the first sheath 5 is rotated, i.e. after making to spend crust pin 2
Crust pin 2 can be made to return in the first sheath 5, it is not necessary to return set the first sheath 5, safe and convenient to use.
Correspondingly, the second sheath 6 arranges the second female thread 61, spiral shell in second near the inside of the one end at the middle part of handle 1
Stricture of vagina 61 can be suitable with the 3rd external screw thread the 15, the 4th external screw thread 16.When second female thread 61 matches with the 3rd external screw thread 15, tweezer
Folder 3 is positioned at the second sheath 6, and when the second female thread 61 matches with the 4th external screw thread 16, tweezer 3 is positioned at outside the second sheath 6.Tweezer
Folder 3 can be only made up of two jig arm, it is also possible to is to arrange spring 4 between two jig arm.
The effect of the projection 17 in the middle part of handle 1 is, when the first sheath 5 and the second sheath 6 respectively with the second external screw thread 13
Time adaptive with the 4th external screw thread 16, make the first sheath 5 and the second sheath 6 all can be relatively fixed with handle 1, it is ensured that even if gripping
First sheath 5 or the second sheath 6, still can normally make to spend crust pin 2 and tweezer 3.For proof strength, protruding 17, first collar 11
It is an entirety with the second collar 14 and handle 1.Due to meeting gripping handle the 1, first sheath 5 and the outside of the second sheath 6 in using,
The outer surface of handle the 1, first sheath 5 and the second sheath 6 arranges anti-slip veins.
For the ease of producing, the first sheath 5 is identical with the second sheath 6, is i.e. that the first sheath 5 and the second sheath 6 can
The most general.Additionally, the length of the first sheath 5 and the second sheath 6 is equal, and it is the half of the length of described handle 1, this
Sample can fully expose crust pin 2 and tweezer 3.Blunt needle buttonhole puncturing goes to handle 1 two ends of crust device to be respectively provided with crust pin 2 and tweezer
3, contribute to carrying out crust operation, and after using, go crust pin 2 and tweezer 3 all without returning set operation, it is to avoid to stab, operation side
Just and use safety.
