[0030] Please refer to Figures 1-4 , a side distance measuring caliper for measuring a workpiece 100, wherein the workpiece 100 has a groove, and the workpiece 100 has a groove bottom hole 101 at the bottom of the groove, wherein the side distance measuring caliper comprises:

[0031] A main ruler mechanism 1, the main ruler mechanism 1 comprises a main ruler 11 and a measuring head 12, the main ruler 11 extends in a first direction, and the end of the main ruler 11 has a through hole, the measuring head 12 is arranged in the through hole, and the side wall of the measuring head 12 abuts against a first fastener 4 arranged through the main ruler 11; the end of the measuring head 12 is used for abutting against the edge of the groove bottom hole 101;

[0032] A connecting plate 2, the connecting plate 2 has a first end and a second end arranged oppositely, the first end of the connecting plate 2 is sleeved on the main ruler 11, and the side wall of the main ruler 11 abuts against a second fastener 5 arranged through the first end of the connecting plate 2;

[0033] A sub-ruler mechanism 3, the sub-ruler mechanism 3 comprises a sub-ruler block 31, the sub-ruler block 31 has a through slot, the second end of the connecting plate 2 is arranged in the through slot, and the second end of the connecting plate 2 abuts against a third fastener 6 arranged through the sub-ruler block 31;

[0034] Wherein, the extension direction of the through hole is perpendicular to the first direction, and the sub-ruler block 31 has an end face 311 for abutting against the workpiece 100 on the side facing the measuring head 12.

[0035] Through the above structure, in use, the operator only needs to push the connecting plate 2 to drive the vice ruler block 31 of the vice ruler mechanism 3 away from the main ruler 11, so that the edge distance measuring caliper has the maximum opening angle, so as to be inserted into the corresponding workpiece 100, and then be sleeved on the workpiece 100, specifically, the measuring head 12 is pushed in the through hole of the main ruler 11, so that the end of the measuring head 12 abuts against the edge position of the groove bottom hole 101, automatic positioning is realized, finally the first fastener 4 is tightened to realize the locking of the measuring head 12, then the vice ruler block 31 is found in the appropriate position along the second up-down sliding of the connecting plate 2, and the end face 311 of the vice ruler block 31 is close to the workpiece 100, finally the second fastener 5 is tightened to realize the locking of the vice ruler block 31 along the first direction position, and the third fastener 6 is tightened to realize the complete locking of the vice ruler block 31. At this time, the measuring head 12 is coaxial with the groove bottom hole 101, and the end face 311 of the vice ruler block 31 is close to the corresponding side wall of the workpiece 100, so that the reading can be made according to the dislocation of the main ruler 11 relative to the connecting plate 2.

[0036] In the above use process, the operator can realize stable reading by adjusting the three movable parts of the measuring head 12, the connecting plate 2 and the vice ruler block 31 respectively and locking the positions by the first fastener 4, the second fastener 5 and the third fastener 6, the adjustment range is large, it is suitable for workpieces 100 and groove bottom holes 101 of various sizes, the operation is convenient, one-time reading can be realized, and the detection efficiency is improved.

[0037] Further, the end face 311 of the vice ruler block 31 has a concave groove 312 for accommodating burrs on the surface of the workpiece 100. Specifically, see Figure 2 , considering that the outer wall of the general workpiece 100 cannot be perfect and flawless, there may be burrs and other protruding structures, and when the vice ruler block 31 of the vice ruler mechanism 3 used for measurement abuts on the burr, the burr may lift the vice ruler block 31, affecting the measurement result. In order to avoid the above situation, the embodiment combines the characteristics of convenient adjustment, and sets the groove 312 for accommodating the burr position on the vice ruler block 31, and through flexible adjustment of the position of the vice ruler block 31, the groove 312 of the vice ruler block 31 is just at the position of the burr, avoiding the influence of the burr on the measurement result.

[0038] Further, the end of the main ruler 11 is thickened and block-shaped at the connection with the measuring head 12. Through the above structure, the stability of the fixing of the measuring head 12 of the embodiment can be effectively improved. At the same time, the above position can also be marked with a deviation value (the radius of the measuring head 12) as shown in Figure 1 , so that the operator can intuitively understand the specific size.

[0039] Further, the end of the first fastener 4, the second fastener 5 and the third fastener 6 is provided with a handle for hand screwing.
