The threaded rod 63 will expand and contract on the inner wall of the side plate 62. Under the limitation of the slider 67 and the chute 68, the threaded rod 63 will drive the clamping plate 64 to move synchronously until the rubber plates 69 on one side of the two clamping plates 64 completely clamp the motor output end connected to the output shaft 5. Then rotate the first nut 66 so that one side of the first nut 66 abuts against one side of the side plate 62. Then the first nut 66 can limit one end of the first threaded rod 63, and further can limit the clamping plate 64, which is beneficial to preventing the fixing of the clamping plate 64 to the motor output end from loosening. Then it can assist in fixing the output shaft 5 and the motor output end, which is beneficial to preventing the problem of unstable connection between the motor output end and the output shaft 5 of the dynamometer; when it is necessary to install the heat dissipation plate 7, insert the heat dissipation plate 7 into the inner wall of the auxiliary groove 81, insert the round hole block 82 into the inner wall of the card slot 83, and make the threaded pin 84 insert into the inner wall of the round hole block 82.
