A detection reference block 5 is disposed at one end of the movable shaft 4. A detection pin 6 is disposed on the side of the detection reference block 5 away from the movable shaft 4. A toggle member 7 is connected to the movable shaft 4. The toggle member 7 passes through the operating hole 3 and is movably disposed in the operating hole 3. A support block 8 is disposed on the side of the fixed base 1 away from the detection pin 6. A detection space 9 is provided between the support block 8 and the fixed base 1. A dial indicator guide sleeve 10 is mounted on the support block 8 and is coaxially disposed with the movable hole 2. A dial indicator 11 is detachably inserted into the dial indicator guide sleeve 10. The probe of the dial indicator 11 extends into the detection space 9 and is used to abut against the end face of the movable shaft 4.

[0020] In practical applications, under normal conditions, dial indicator 11 is detached from dial indicator guide sleeve 10, and the detection reference block 5 and detection pin 6 on the movable shaft 4 retract into the movable hole 2. When the surface to be inspected on workpiece 19 is outside the detection pin 6, the operator moves the actuating element 7 towards workpiece 19, causing the actuating element 7 to move within the operating hole 3. The moving actuating element 7 drives the movable shaft 4, along with the detection reference block 5 and detection pin 6, to move towards workpiece 19 until the detection pin 6 is inserted into the hole on the surface to be inspected on workpiece 19. The measuring pin 6 detects the position of the hole on the surface to be inspected of workpiece 19. When the measuring pin 6 cannot be inserted into the hole, it proves that the hole position of workpiece 19 is off-center, and workpiece 19 is unqualified. When the measuring pin 6 can be inserted into the hole, the reference surface of the measuring reference block 5 contacts the surface to be inspected of workpiece 19. At this time, the dial indicator 11 is inserted into the dial indicator guide sleeve 10 until the probe of the dial indicator 11 extends into the measuring space 9 and abuts against the end face of the movable shaft 4.
