It is engaged, the outer peripheral face of described sleeve pipe is radial ringed to be arranged with spacing preiection, the opposite sides of the cross section of the spacing preiection
Angle between wall is in 60 degree of settings；The upper end of the shank has been radially arranged annular groove, and up and down the two of the annular groove
Side wall is obliquely installed；The spacing preiection is slidably matched with the annular groove；The outer wall of the shank and described sleeve pipe
Inwall is slidably matched, and the cavity top surface of described sleeve pipe is set in hemisphere face, and the cavity top surface of described sleeve pipe and described sleeve pipe
The tangent setting of cavity inner wall.
Wherein, the first cable-through hole is provided through in the middle part of the catch.
Wherein, the cavity top surface of described sleeve pipe is provided through the second cable-through hole.
Wherein, first cable-through hole and the second cable-through hole are coaxially disposed.
Wherein, the spacing between the root of the upper side wall of the annular groove and the root of lower wall is arranged to 15mm.
The beneficial effects of the utility model：The utility model includes sleeve pipe, slided along the cavity length direction of described sleeve pipe
The shank of setting, the stage clip for being arranged at the needle tip and the catch being connected at the top of the cavity of described sleeve pipe, the gear
Piece is engaged with the upper surface of the stage clip, and the outer peripheral face of described sleeve pipe is radial ringed to be arranged with spacing preiection, the limit convex
Angle between the two lateral walls for the cross section risen is in 60 degree of settings；The upper end of the shank has been radially arranged annular groove,
The two side up and down of the annular groove is obliquely installed；The spacing preiection is slidably matched with the annular groove；The pin
The outer wall of bar and the inwall of described sleeve pipe are slidably matched, and the cavity top surface of described sleeve pipe is set in hemisphere face, and described sleeve pipe
Cavity top surface and the tangent setting of the cavity inner wall of described sleeve pipe.With this structure design, pass through matching somebody with somebody for annular groove and spacing preiection
Close, can effectively limit the stroke of shank back and forth movement, and Stability Analysis of Structures is reliable.
Brief description of the drawings
Fig. 1 is a kind of structural representation of testing needle of the utility model.
Embodiment
It is shown below in conjunction with the accompanying drawings and the technical solution of the utility model is further illustrated by embodiment.
A kind of testing needle, including sleeve pipe 1, the cavity length along described sleeve pipe 1 are provided with reference to shown in Fig. 1, in the present embodiment
The shank 2 set is slided, the stage clip 3 on the top of shank 2 is arranged at and is connected in the cavity top of described sleeve pipe 1 in degree direction
The catch 4 in portion, the catch 4 are engaged with the upper surface of the stage clip 3, and the outer peripheral face of described sleeve pipe 1 is radial ringed to be arranged with
Spacing preiection 11, the angle between the two lateral walls of the cross section of the spacing preiection 11 are set in 60 degree；The shank 2
Upper end has been radially arranged annular groove 21, and the two side up and down of the annular groove 21 is obliquely installed；The spacing preiection 11
It is slidably matched with the annular groove 21；The outer wall and the inwall of described sleeve pipe 1 of the shank 2 are slidably matched, described sleeve pipe 1
Cavity top surface is set in hemisphere face, and the cavity top surface of described sleeve pipe 1 and the tangent setting of cavity inner wall of described sleeve pipe 1, described
The middle part of catch 4 is provided through the first cable-through hole 41, and the cavity top surface of described sleeve pipe 1 is provided through the second cable-through hole 12,
The cable-through hole 12 of first cable-through hole 41 and second is coaxially disposed, the root of the upper side wall of the annular groove 21 and lower wall
Spacing between root is arranged to 15mm.
Using said structure design, by the cooperation of annular groove and spacing preiection, it can effectively limit shank and come and go fortune
Dynamic stroke, and then make it that test needle stroke is controllable, facilitate the debugging of testing needle, and it is steady with the test needle construction of this structure design
It is fixed reliable.
Technical principle of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and the limitation to scope of protection of the utility model can not be construed in any way.Based on explanation herein,
