Then the pressing piece is tightly attached to the measuring scale by rotating the screw. When measuring, the connecting plate outside is tightly attached to the inner chamber for measurement. The diameter of the inner chamber can be obtained by reading the measuring scale and the vernier caliper body.

[0008] Preferably, the fixed block is connected and fixed with the measuring rod of the vernier caliper body, and the width sum of the fixed block and the two connecting plates is the same as the width of the measuring rod.

[0010] Preferably, a through hole is formed in the side outer wall of the fixed block, a guide rod is slidably inserted into the through hole, and the two ends of the guide rod are connected and fixed with the two connecting plates.

[0011] The two connecting plates and the measuring scale are supported and reinforced through the sliding cooperation of the guide rod and the fixed block.

[0012] Preferably, a mounting hole is formed in the top of the fixed block, and the mounting hole is located above the measuring scale.

[0013] The fastening assembly is connected and fixed through the mounting hole.

[0014] Preferably, a push block is fixed on the rod wall of the insertion rod, and a telescopic spring is connected between the outer wall of one end of the insertion rod and the inner wall of one end of the connecting shell.

[0018] The beneficial effects of the utility model are:

[0019] By rotating the screw rod, the pressing plate is moved away from the measuring scale, so that the measuring scale can be inserted and connected in the fixed block, the connecting plate on the inner side is abutted with the fixed block, and then the pressing plate is tightly contacted with the measuring scale by rotating the screw rod. When measuring, the connecting plate on the outer side is tightly contacted with the inner cavity for measurement. The diameter of the inner cavity can be obtained by reading the measuring scale and the vernier caliper body, and the problem that the inner cavity diameter of the small-diameter large-inner-cavity part cannot be accurately measured in the prior art is effectively solved.
