A kind of angle adjustable puncture needle fixer of the utility model including collet, fixing pipe and screws button；The collet
On offer adjustment hole, the inner wall of the adjustment hole is spherical surface, and upper end opening diameter is less than lower ending opening diameter；The adjusting
Hole surrounding offers multiple threaded holes for being used to set jackscrew；Bulb and top half of the fixing pipe including lower half portion
Stretched portion offers the mounting hole for penetrating through the bulb and stretched portion in fixing pipe；The fixing pipe passes from below through the tune
Knothole makes bulb be located in the adjustment hole, and passes through jackscrew and fix；Stretched portion top is provided with external screw thread, stretched portion
It is opened up on tube wall with external screw thread position there are three vertical notch, upper end opening diameter of the stretched portion with external screw thread position is less than
Lower ending opening diameter；It is described screw to buckle to offer screw hole, described screw is provided with internal thread on the inner wall of hole；It is described to screw button
It is threaded in the stretched portion of fixing pipe.
Further, three notches are evenly arranged, and the angle between each two notch is 120 °.
Further, the quantity of the threaded hole is four, respectively from the side of the front, rear, left and right of the adjustment hole four
To the fixation bulb.
Further, the integral planar shape of the collet is round or square.
Further, the integral planar shape for screwing button is round or square.
Compared with prior art, the advantageous effects of the utility model are as follows：
The utility model is penetrated in collet from below using fixing pipe, has the ball coordinated with the bulb of fixing pipe in collet
Face allows fixing pipe arbitrarily to rotate, and passes through jackscrew and be fixed, and it is accurate, secured that angle is fixed；There is placement to wear in fixing pipe
The mounting hole of pricker (ablation needle) tightens the straight body upper end of fixing pipe, by puncture needle (ablation needle) by screwing button
Clamping is completed to fix, applied widely；The utility model is simple in structure, easy to use, at low cost, and using effect is good, convenient for general
And.

Specific embodiment
As shown in figures 1-8, a kind of one of which specific embodiment of angle adjustable puncture needle fixer, including collet 1,
Fixing pipe 2 and button 3 is screwed, the angle of this fixator is allow arbitrarily to adjust as needed.Adjustment hole is offered on the collet 1
4, the inner wall of the adjustment hole 4 is spherical surface, and upper end opening diameter is less than lower ending opening diameter.Collet in this specific embodiment
1 integral planar shape is square, naturally it is also possible to it is round, when collet is round, and edge anti-slop serrations, to increase
Big frictional force.4 surrounding of adjustment hole is opened up there are four the threaded hole 6 for being used to set jackscrew 5, respectively from the adjustment hole 4
Front, rear, left and right four direction fixes the bulb 201.The fixing pipe 2 includes bulb 201 and the top half of lower half portion
Stretched portion 202, the mounting hole 7 for penetrating through the bulb 201 and stretched portion 202 is offered in fixing pipe 2.In use, by described in
Fixing pipe 2 passes from below through the adjustment hole 4, and bulb 201 is made to be located in the adjustment hole 4, and stretched portion 202 passes through collet, position
Above collet, angle of the bulb in adjustment hole can be rotated as needed, is fixed after angle is suitable by jackscrew 5, make solid
Angle of the fixed tube in collet is fixed.202 top of stretched portion is provided with external screw thread, in this specific embodiment, the fixation
The stretched portion 202 of pipe 2 is opened up on the tube wall with external screw thread position there are three vertical notch 8, three 8 uniform cloth of notch
It puts, the angle between each two notch 8 is 120 °.Upper end opening diameter of the stretched portion 202 with external screw thread position is opened less than lower end
