Stroke during shank back and forth movement can not be effectively limited during the back and forth movement of direction, and then is not easy to test calculating and the pipe of stroke
Control.
Utility model content
The utility model provides a kind of needle bar stroke and fixed, and the reliable testing needle of stable testing.
To use following technical scheme up to this purpose, the utility model：
The testing needle that a kind of stroke is fixed, including sleeve pipe, slided along the cavity length direction of described sleeve pipe set shank,
And the stage clip of the needle tip is arranged at, and the outer peripheral face of described sleeve pipe has been radially arranged first annular groove, and described first
The circumferentially-spaced salient point for being evenly equipped with multiple inwardly projections of the bottom land of annular groove；The upper end of the shank has been radially arranged the second ring
Connected in star, the bottom land of second annular groove offer multiple chutes along the shank length direction, the chute with it is corresponding
The salient point be slidably matched, the outer wall of the shank and the inwall of described sleeve pipe are slidably matched, the first annular groove with
The second annular groove gap coordinates.
Wherein, the two lateral walls of the cross section of the first annular groove be arranged in parallel.
Wherein, the two lateral walls of the cross section of second annular groove be arranged in parallel.
Wherein, the spacing between the two lateral walls of second annular groove is more than the first annular groove
Spacing between two lateral walls.
Wherein, dismountable top cover is provided with the top of the cavity of described sleeve pipe, was provided through in the middle part of the top cover
String holes.
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 and the stage clip for being arranged at the needle tip, the outer peripheral face of described sleeve pipe have been radially arranged first annular recessed
Groove, the circumferentially-spaced salient point for being evenly equipped with multiple inwardly projections of the bottom land of the first annular groove；The upper end of the shank is radially
The second annular groove is provided with, the bottom land of second annular groove offers multiple chutes, institute along the shank length direction
Chute to be stated to be slidably matched with the corresponding salient point, the outer wall of the shank and the inwall of described sleeve pipe are slidably matched, and described
One annular groove coordinates with the second annular groove gap.With this structure design, pass through first annular groove and the second annular
The setting of groove, the stroke of shank back and forth movement can be effectively limited, passes through the cooperation of chute and salient point in addition so that shank is slided
It is dynamic more reliable and more stable.
Brief description of the drawings
Fig. 1 is the structural representation for the testing needle that a kind of stroke of the utility model is fixed.
Embodiment
It is shown below in conjunction with the accompanying drawings and the technical solution of the utility model is further illustrated by embodiment.
Provide the testing needle that a kind of stroke is fixed with reference to shown in Fig. 1, in the present embodiment, including sleeve pipe 1, along described sleeve pipe
Slide the shank 2 set and the stage clip 3 for being arranged at the top of shank 2, the periphery of described sleeve pipe 1 in 1 cavity length direction
For face diameter to first annular groove 11 is provided with, the bottom land of the first annular groove 11 is circumferentially-spaced to be evenly equipped with multiple inside projections
Salient point 111；The upper end of the shank 2 has been radially arranged the second annular groove 21, the bottom land edge of second annular groove 21
The length direction of shank 2 offers multiple chutes 211, and the chute 211 is slidably matched with the corresponding salient point 111, institute
