As a further optimization scheme of the utility model, press the splenium to include two handles, two the handle all with the disc rotates to be connected, two it installs the support, two to all rotate on hand the support respectively with first semi-ring cover with second semi-ring cover fixed connection.

As the utility model discloses a further optimization scheme, ring groove is the dovetail groove, reduces from the opening part width gradually.

As the utility model discloses a further optimization scheme, two are adjacent ring groove's the side that is close to each other is crossing.

As a further optimization scheme of the utility model, round hole and a plurality of fretworks have been seted up on the disc, the puncture pipe box runs through the round hole.

The beneficial effects of the utility model reside in that:

the utility model discloses a set up the position of the fixed puncture ware of being convenient for of fixer, compare in traditional mode through the screw thread increase with skin frictional force with fixed puncture ware, fixed stability is higher, and the puncture ware is difficult for the slippage, and the injury that causes the human body is littleer, is convenient for adjust the position of fixer moreover, is convenient for control the depth of insertion of puncture ware.

Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

Example 1

As shown in fig. 1 to 5, a puncture outfit comprises a fixing cover 1, a positioning guide cover 2 is arranged on the fixing cover 1, a locking fixing cover 3 is arranged on the positioning guide cover 2, a puncture tube sleeve 5 is arranged on one side of the locking fixing cover 3, an air injection valve 4 is arranged on the puncture tube sleeve 5, a puncture cone 6 is arranged in the puncture tube sleeve 5, one end of the puncture cone 6 extends out of the puncture tube sleeve 5, a plurality of annular clamping grooves 7 are arranged on the puncture tube sleeve 5, the annular clamping grooves 7 are trapezoidal grooves, the inward width of the opening part is gradually reduced, the mutually close side surfaces of two adjacent annular clamping grooves 7 are intersected, a fixer is sleeved on the puncture tube sleeve 5 and comprises a disc 8, a pressing part and a clamping part, the disc is connected with the clamping part through the pressing part, the clamping part comprises a first half ring sleeve 10 and a second half ring sleeve 11, first half ring cover 10 with second half ring cover 11 rotates through rotating member 14 and connects, rotating member 14 is last to be provided with the torsional spring (not drawn in the picture), first half ring cover 10 with the inboard of second half ring cover 11 is provided with tooth 12 and lower tooth 13 respectively, go up tooth 12 with lower tooth 13 all with ring groove 7 looks adaptation.
