Since disc seat 1 is shielded, it is difficult to determine whether locating bolt 12 is horizontal after being screwed in. When the force applied during screwing in of locating bolt 12 is uneven, the screw rod is easily deviated from the correct position and twisted, causing disc seat 1 to be inclined, and then causing the positions of two dial gauges 6 to be not perpendicular, and then affecting the accuracy of the measurement value. After locating bolt 12 is screwed in, disc seat 1 is attached to one side of half shaft, and half shaft can push out two elastic components 7. When locating bolt 12 is twisted, the lengths of two elastic components 7 pushed out are not the same.

Since disc seat 1 is shielded, it is difficult to determine whether locating bolt 12 is horizontal after being screwed in. When the force applied during screwing in of locating bolt 12 is uneven, the screw rod is easily deviated from the correct position and twisted, causing disc seat 1 to be inclined, and then causing the positions of two dial gauges 6 to be not perpendicular, and then affecting the accuracy of the measurement value. After locating bolt 12 is screwed in, disc seat 1 is attached to one side of half shaft, and half shaft can push out two elastic components 7. When locating bolt 12 is twisted, the lengths of two elastic components 7 pushed out are not the same. By observing the corresponding length positions of two elastic components 7 on two measuring plates 8, it can be determined whether locating bolt 12 is twisted.

[0024] In a preferred embodiment, elastic component 7 includes movable rod 701, tension spring 702 sleeved on the outside of movable rod 701, and indicator plate 703 fixed on the top of movable rod 701.

[0025] It should be noted here that after the positioning bolt 12 is screwed in, the disc seat 1 is attached to one side of the half shaft, the half shaft can push out the two movable rods 701, and pull the two tension springs 702 respectively. Through the two indicator plates 703 arranged, the length position of the two movable rods 701 on the two measuring plates 8 respectively can be observed.

[0026] In a preferred embodiment, the top of the tension spring 702 is connected with the top of the movable rod 701, and the bottom of the tension spring 702 is connected with the outer wall of the top of the disc seat 1.

[0027] It should be noted here that the movable rod 701 can pull the tension spring 702 when it is pushed out, which helps the subsequent reset of the movable rod 701.

[0028] In a preferred embodiment, the guide assembly 10 includes a guide block 1001 and a connecting plate 1002 fixed to the bottom of the guide block 1001.

[0029] It should be noted here that the guide block 1001 is connected with the moving block 302 through the connecting plate 1002, which can limit and guide the moving block 302.

[0030] In a preferred embodiment, the two measuring plates 8 are provided with scale lines 11 on the outer walls of the opposite sides.

[0031] It should be noted here that it is convenient and intuitive to observe the length distance of the movable rod 701 being pushed out.
