[0048] Optionally, the third slider 600 is provided with a third U-shaped groove 610, the support 200 is inserted into the third U-shaped groove 610, and the third threaded fastener 620 can adjust the distance between the opposite two side walls of the third U-shaped groove 610, so as to clamp or release the support 200.

[0050] Optionally, the third U-shaped groove 610 includes a first side wall 611, a second side wall 612 and a third side wall 613 connected in sequence, the third threaded fastener 620 connects the first side wall 611 and the third side wall 613, the second side wall 612 is provided with a V-shaped groove 6121, and the support 200 is provided with a V-shaped protrusion, which is inserted into the V-shaped groove 6121 in the direction of gravity. In this way, since the V-shaped groove 6121 has two guide surfaces in opposite directions, under the action of gravity, the V-shaped protrusion and the V-shaped groove 6121 always have a tendency to be centrally inserted, so that the measuring rod 100 and the support 200 can be kept stable.
[0051] Optionally, the fourth slider 700 is provided with a fourth U-shaped groove, the measuring rod 100 is inserted into the fourth U-shaped groove, and the fourth threaded fastener 710 can adjust the distance between the opposite two side walls of the fourth U-shaped groove, so as to clamp or release the measuring rod 100.

[0053] Optionally, the second guide rod 800 is inserted into the opening in the depth direction of the fourth U-shaped groove and connected by the fourth threaded fastener 710.
[0054] Exemplarily, the second guide rod 800 and the side wall of the fourth U-shaped groove form a mouth-shaped channel, the measuring rod 100 is inserted into the channel and can slide along the first straight line. In the thickness direction of the fourth U-shaped groove, the size of the second guide rod 800 is D4, D4≤D1.
[0055] Optionally, the two ends of the measuring rod 100 opposite to each other are connected with the abutting piece 110, and the abutting piece 110 can be partially inserted into the tooth groove of the gear ring. In this way, the abutting piece 110 can be inserted into the tooth groove to limit the position, and during the measurement, the relative stability of the measuring rod 100 and the gear ring is maintained.
[0056] Optionally, the abutting piece 110 and the measuring rod 100 are detachably connected. In this way, the abutting piece 110 can be replaced according to the specific shape of the gear ring to be measured this time.
[0057] Further, in the width and / or depth direction of the fourth U-shaped groove, the size of the abutting piece 110 is greater than the gap size of the fourth U-shaped groove.
[0058] In this way, since the abutting piece 110 cannot pass through the fourth U-shaped groove along the first straight line, the abutting piece 110 can prevent the measuring rod 100 from exiting the fourth U-shaped groove when the measuring rod 100 moves along the first straight line, thereby maintaining the relative position of the measuring rod 100 and the supporting piece 200.
[0059] Further, the abutting piece 110 is a cylinder. In this way, the measuring rod 100 contacts the gear ring through the circumferential surface of the abutting piece 110, and the contact surface is relatively smooth and gentle, which can reduce stress concentration and avoid damage to the measuring rod 100 and the gear ring during the measurement.
