In the present embodiment, a bushing 6 is disposed in the through hole 30 of the movable seat 3, and the connecting rod 51 passes through the bushing 6 and is slidably engaged with the bushing 6. Optionally, the bushing 6 is a copper sleeve. With the bushing 6, surface wear of the via 30 due to friction between the via 30 and the plug gauge assembly 5 is avoided.
The second driving mechanism is disposed on the movable base 3 and can be lifted and lowered synchronously with the movable base 3. A second drive mechanism is connected to the connecting rod 51 for driving the plug gauge assembly 5 down or up to extend the plug gauge 52 down to measure the inner diameter of the end coil of the spring to be tested or retract up to avoid interfering with the depression of the load cell 4.
