One end of the rotating shaft 9 is connected to the connecting rod 10. The bearing 8 is wrapped by the clamp 7 to make the bearing 8 stable. The clamp 7, the first clamping seat 4 and the second contact pair support the bearing 8. The rotating shaft 9 utilizes the rotation function of the bearing 8, which is more conducive to the rotation of the rotating shaft 9 and improves the test accuracy.
[0024] A counterweight hole 11 is provided on the inner side of the connecting rod 10, and a locking bolt 12 is threadedly connected to the inner wall of the connecting rod 10. The counterweight block is accommodated through the counterweight hole 11. After the counterweight block is placed into the counterweight hole 11, it is fixed by the locking bolt 12 to increase the stability of the counterweight block.
[0025] The other end of the connecting rod 10 is provided with a cross slot 13, and one side of the adapter 2 is connected to a cross pin 14.
