Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of test probe of instrument and meter, including shell
Body 1 and guard block 2 are fixedly installed probe inner conductor 3 inside the shell 1, and the probe inner conductor 3 is far from shell 1
One end is fixedly installed with test probe 4, and 1 surface of shell is movably installed with support rod 5 by pin shaft, and the support rod 5 pushes up
Portion is fixedly installed LED light 6, and 1 surface of shell is embedded to be equipped with switch 7, and the guard block 2 is movably arranged on shell 1
Outer surface, 2 lower end surface of guard block are fixedly installed sliding block 8, and 1 surface of shell is offered to match with sliding block 8
Sliding slot 9, embed at the top of the shell 1 and be provided with limit spring 10, be fixedly installed with spacing ball at the top of the limit spring 10
11, the 2 lower end surface bottom of guard block offers the groove 12 to match with spacing ball 11, and the guard block 2 is far from limit
The side fixation of position ball 11 offers bayonet 13, and 1 upper surface of shell is fixedly installed with fixture block 14.
Several balls 15 are filled with inside the guard block 2, the ball 15 is covered with inside guard block 2, rises
To the effect of good buffer protection；2 bottom of guard block and top outer are fixedly installed anticollision layer 16, the anticollision
16 material of layer are steel material, have good anti-collision effect；The sliding slot 9 is internally provided with sealing ring, in the sliding slot 9
