Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.
Referring to fig. 1 and 2, an embodiment of the present invention includes:
a vernier caliper depth gauge auxiliary gap gauge, comprising: casing 1, the casing divide into procapsid and back casing, the procapsid encloses slide caliper depth of depth chi grip slipper and probe installation cavity and forms bottom reference surface 6 with the back casing together, set up between slide caliper depth of depth chi grip slipper and the probe installation cavity and separate step 103, slide caliper depth chi grip slipper comprises preceding pressure arm 101, back pressure arm 102 and bottom surface, preceding pressure arm 101 is located the upper portion of procapsid, back pressure arm 102 is located the upper portion of back casing, the step face of step 103 is separated to the bottom surface, install fastening screw 2 on the pressure arm 102 of back, the intermediate position of preceding pressure arm 101 sets up the blade observation hole of fretwork. In this way, when measuring, the reference surface of the vernier caliper depth gauge can be placed on the step surface of the separation step 103 by attaching, and then the fastening screw 2 mounted on the rear pressure arm 102 is screwed to fix the reference surface of the vernier caliper depth gauge in the vernier caliper depth gauge clamping seat.
A measuring probe is arranged in the probe mounting cavity, and the total length of the measuring probe is equal to the distance from the step surface of the separation step 2 to the reference surface 6 at the bottom of the shell; the probe is T shape structure, including syringe needle, needle bar 5 and needle file 3, needle file 3 with the cross section assorted slider of probe installation cavity, needle file 3 with install spring 4 between the bottom of probe installation cavity, the bottom central point of probe installation cavity puts and sets up out pinhole 7, the length that goes out pinhole 7 is 0.5~1cm, through the above-mentioned mode the syringe needle of probe can be followed out pinhole 7 direction vernier caliper depth chi's action simultaneous movement. And maintains the reset state when the vernier caliper is not moved.
The working principle of the utility model is as follows:
