[0032] In this embodiment, when in use, first place the bottom of the motor rotor shaft in the clamping rotating seat 106, and insert the top of the motor rotor shaft in the hollow shaft 3, then control the support frame 201 and the fixing ring 202 to move downward, so that the hollow shaft 3 moves downward, at this time, the top of the motor rotor shaft will push the slide plate 302 to move, and then the push plate 1 401 will touch the inner wall of the hollow shaft 3, thereby pushing the push plate 1 401 to move, driving the thin rod 4 to move, and the thin rod 4 will drive the trapezoidal block 1 405 fixed thereon to move. , so that the inclined surface on the trapezoidal block 1 405 cooperates with the inclined surface on the trapezoidal block 2 406. Since the trapezoidal block 1 405 can only move up and down following the thin rod 4, when the inclined surfaces on the trapezoidal block 1 405 and the trapezoidal block 2 406 are against each other, the trapezoidal block 1 405 will push the trapezoidal block 2 406 to move, so that it drives the arc-shaped clamping plate 1 407 to move toward one side of the inner wall of the arc-shaped clamping rod 303, thereby moving the arc-shaped clamping plate 1 407 out and clamping the outer wall of the motor rotor shaft to fix the motor rotor shaft.

[0033] It should be noted that trapezoidal block 1 405, trapezoidal block 2 406 and arc-shaped clamping plate 1 407 are all provided in multiple groups, and the clamping effect can be further improved by multiple groups of arc-shaped clamping plates 1 407 to achieve a stable clamping effect on the motor rotor shaft, and a vertical groove 408 is provided on trapezoidal block 2 406, which can allow the thin rod 4 to pass through, so that multiple trapezoidal blocks 1 405 can be easily connected to the thin rod 4, and a boss is provided on trapezoidal block 2 406, which can slide on the inner wall of the long groove 308 to prevent it from deviating, and a stop block 410 is also provided on trapezoidal block 2 406, which can limit the moving distance of trapezoidal block 1 405 to ensure the use effect.

[0034] Reference Figure 8-Figure 11 An extension plate 504 is slidably connected to the annular plate 5, and a push plate 2 513 is provided at one end of the extension plate 504 outside the annular plate 5. A third gear tooth 505 is provided on the extension plate 504, and a fourth gear tooth 507 is provided at the bottom of the push rod 501. A gear set 506 is provided in the annular plate 5, and the gear set 506 includes a left gear, an intermediate gear and a right gear that mesh with each other. The third gear tooth 505 meshes with the left gear on the gear set 506, and the fourth gear tooth 507 meshes with the right gear on the gear set 506.

[0035] Reference Figure 8-Figure 11A third spring 503 is provided between the annular plate 5 and the second arc-shaped clamping plate 502, and the third spring 503 is sleeved on the outer wall of the push rod 501. A groove 508 is provided on the moving rod 306, and a guide rod 511 is provided on the inner wall of the groove 508. A groove 510 is provided on the extension plate 504, and the guide rod 511 is inserted in the groove 510. A protrusion 509 is fixedly connected to the top of the extension plate 504, and the protrusion 509 is slidably connected in the groove 508. The guide rod 511 is slidably connected to the protrusion 509, and a fourth spring 512 is provided between the protrusion 509 and the inner wall of the groove 508. The fourth spring 512 is sleeved on the outer wall of the guide rod 511, and a connecting rod 309 is provided on the outer wall of the hollow shaft 3. A retaining ring 310 is fixedly connected to the connecting rod 309, and a notch is provided on the retaining ring 310. Through the provided notch, the top of the motor rotor shaft can be more conveniently connected to the hollow shaft 3.

[0036] In this embodiment, when the slide plate 302 moves, the arc clamping rod 303 is also driven to move. When the arc clamping rod 303 moves, the first gear tooth 304 is meshed with the auxiliary gear 305, so that the auxiliary gear 305 rotates, and the second gear tooth 307 drives the moving rod 306 to move. Since the arc clamping rod 303 and the moving rod 306 are respectively arranged on both sides of the auxiliary gear 305, when the arc clamping rod 303 moves into the hollow shaft 3, the moving rod 306 is moved in the opposite direction. Therefore, the moving rod 306 is moved out of the hollow shaft 3, thereby driving the annular plate 5 to move outward, and then the retaining ring 310 is engaged with the push plate 513. The third gear tooth 505 on the outer wall of the extension plate 504 meshes with the left gear in the gear set 506, and then the right gear in the gear set 506 is driven to mesh with the fourth gear tooth 507 at the bottom of the push rod 501, thereby driving the push rod 501 to move. Since there are three gears in the gear set 506, and the third gear tooth 505 and the fourth gear tooth 507 are respectively meshed with the left gear and the right gear at both ends of the gear set 506, the moving direction of the push rod 501 can be guaranteed. When the extension plate 504 moves upward, it can drive the push rod 501 to move toward the inside of the annular plate 5, thereby achieving a clamping effect.

[0037] It should be noted that the extension plate 504 and the push rod 501 are staggered and perpendicular to each other. Therefore, the extension plate 504 and the push rod 501 will not interfere with each other when moving, and the fourth gear tooth 507 only meshes with the right gear in the gear set 506, and does not mesh with the left gear and the middle gear. The guide rod 511 and the groove 2 510 are set to limit the extension plate 504, making its movement more stable.

[0038] In this embodiment, after the operation on the motor rotor shaft is completed, when it is necessary to remove it, the hollow shaft 3 is directly controlled to move upward, so that the various parts can be automatically separated, and then the thin rod 4 can be automatically reset under the action of the first spring 403, which is convenient for repeated use. The second spring 409 is set, and the arc clamping plate 1 407 can be automatically reset, losing the clamping effect on the motor rotor shaft, and under the action of gravity, the slide plate 302 and the like will be automatically reset. Specifically, in actual use, a counterweight block can be set on the arc clamping rod 303 to make it easier to reset, or a spring can be set between the slide plate 302 and the inner wall of the hollow shaft 3 to improve the reset effect; the arc clamping plate 2 502 can be reset by the third spring 503, and the extension plate 504 can be automatically reset by the fourth spring 512, which is convenient for repeated use.

[0043] In the present invention, multiple arc-shaped bottom plates 107 are provided. When in use, the bottom of the motor rotor shaft is first placed in the clamping rotating seat 106 so that it is placed between multiple arc-shaped bottom plates 107. Then, under the action of the elastic member 109, the arc-shaped bottom plate 107 is pressed against the motor rotor shaft to position it. Secondly, the bolt 108 can be tightened so that one end of the arc-shaped bottom plate 107 placed in the clamping rotating seat 106 is tightly pressed against the arc-shaped bottom plate 107, thereby improving the clamping and fixing effect. A rubber pad is provided on the arc-shaped bottom plate 107 to protect the motor rotor shaft.
