When the top of the pressing plate 14 contacts the bottom of the resisting bar 15, the resisting bar 15 can push the pressing plate 14 to move. Two sliding rods 16 are fixedly connected to one side of the vertical plate 10 close to the support plate 9. The sliding rods 16 slide through the support plate 9 to provide guidance for the movement of the vertical plate 10. A limiting plate 19 is fixedly connected between the ends of the two sliding rods 16 away from the vertical plate 10. A spring 2 17 is arranged on the outer side of the sliding rod 16.

The bottom of the electric telescopic rod 18 is fixedly connected to the top of the device base 1, and the support plate 9 is pulled up and down by the electric telescopic rod 18;

[0032] When the electric telescopic rod 18 is in operation, it can push the support plate 9 to move upward, so that the support plate 9 drives the bottom plate 11 and the pressure plate 14 on the vertical plate 10 to move upward through the sliding rod 16, and the bottom plate 11 pushes the mounting ring 12 to move synchronously through the pulling block 13, so that the mounting ring 12 drives the knocking tube 6 to compress the spring 17. When the top of the pressing plate 14 contacts the bottom of the resisting bar 15, the pressing plate 14 moves along the inclined surface at the bottom of the resisting bar 15, so that the pressing plate 14 drives the sliding rod 16 to move along the inner side of the support plate 9 through the vertical plate 10, compressing the spring 17. At the same time, the vertical plate 10 drives the bottom plate 11 away from the pulling block 13.

As a result, as the electric telescopic rod 18 drives the support plate 9 to move back and forth, the transmission gear body 4 is repeatedly and evenly hammered, and the transmission gear body 4 is installed on the motor shaft of the motor body 3. The elastic force of the spring 7 is used to achieve elastic knocking on the transmission gear body 4, thereby achieving the effect of smoothly installing the transmission gear.

[0034] The user turns the adjusting rod 24, and drives the slider 22 to move along the inner side of the slide box 21 through the thread on the adjusting rod 24, so that the slider 22 squeezes the spring 7 through the fixing plate 23 or relaxes it upwards. The elastic force of the spring 7 can be adjusted according to the installation requirements of the transmission gear body 4 and the motor shaft, and then the hammer force of the knocking tube 6 can be adjusted, thereby achieving the effect of improving the convenience of transmission gear installation.

[0035] The positioning mechanism includes a positioning platform 25 fixedly installed inside the device base 1. The positioning platform 25 extends to the top of the device base 1 and contacts the bottom end of the motor shaft in the motor body 3. The top of the positioning platform 25 is a trapezoidal frustum structure, which abuts against the bottom of the motor shaft of the motor body 3 to provide support for the motor shaft. A bidirectional screw 26 is rotatably installed inside the positioning platform 25. Both ends of the bidirectional screw 26 extend to the outside of the device base 1. The internal limit sliding of the device base 1 has two moving bars 27 that respectively cooperate with the threads at both ends of the bidirectional screw 26. Rotating the bidirectional screw 26 can drive the two moving bars 27 to move closer to or away from each other. Two symmetrically distributed brackets 28 are fixedly connected to the top of the moving bar 27. A slide groove for limiting the sliding of the brackets 28 is provided on the top of the device base 1. A U-shaped clamping plate 29 is fixedly connected between the two brackets 28. The opposite surfaces of the two U-shaped clamping plates 29 are in contact with the outer side of the motor body 3. The two U-shaped clamping plates 29 provide clamping and positioning for the outer side of the motor body 3. A placement component for placing the motor body 3 is also provided on the top of the device base 1.

[0036] The user places the motor body 3 on the top of the device base 1, rotates the bidirectional screw 26 to drive the two moving bars 27 to move in opposite directions, so that the moving bar 27 drives the bracket 28 to make the U-shaped clamping plate 29 contact with the outer side of the motor body 3, and adopts a synchronous clamping method to push the motor body 3 to the middle position of the top of the device base 1, so that the bottom end of the motor shaft in the motor body 3 contacts with the top of the positioning platform 25, providing support for the bottom end of the motor shaft to prevent the motor shaft from being displaced when it is vibrated, thereby achieving the effect of facilitating and quickly positioning the motor.

[0037] Working principle: First, the user places the motor body 3 on the top of the device base 1, rotates the bidirectional screw 26, and makes the bidirectional screw 26 drive the two moving bars 27 to move in different directions. The two moving bars 27 drive the two U-shaped clamping plates 29 to contact the outside of the motor body 3 through the corresponding brackets 28, and push the motor body 3 to the middle position of the device base 1, and clamp and position it. The motor shaft of the motor body 3 contacts the top of the positioning platform 25. Then, the user puts the transmission gear body 4 to be installed on the top position of the motor shaft, and pushes the mounting plate 5 downward along the slide 2 to make the bottom end of the adjusting rod 24 against the motor. The top of the shaft is fixed, and the mounting plate 5 is fixed. The adjusting rod 24 cooperates with the positioning platform 25 to support and position the motor shaft. Then, the user starts the electric telescopic rod 18, and the two electric telescopic rods 18 respectively pull the corresponding support plates 9 to move upward, so that the support plates 9 drive the bottom plate 11 and the pressure plate 14 on the vertical plate 10 to move upward synchronously through the sliding rod 16. The bottom plate 11 pushes the mounting ring 12 to move through the pulling block 13, so that the mounting ring 12 drives the knocking cylinder 6 away from the transmission gear body 4 and the compression spring 7. When the top of the pressure plate 14 contacts the bottom of the resisting strip 15, the pressure plate 14 moves along the inclined surface at the bottom of the resisting strip 15, so that the pressure plate 14 drives the slide bar 16 to move along the inner side of the support plate 9 through the vertical plate 10. At the same time, the vertical plate 10 drives the bottom plate 11 away from the pull block 13. When the bottom plate 11 is separated from the pull block 13, the rebound force of the spring 1 7 is used to push the knocking tube 6 to move downward quickly to knock the transmission gear body 4. At this time, the electric telescopic rod 18 pulls the support plate 9 to move downward, so that the bottom plate 11 contacts the pull block 13, and the inclined surface at the bottom of the bottom plate 11 moves along the inclined surface at the top of the pull block 13. The pull block 13 pushes the bottom plate 11 to move, so that the bottom plate 11 drives the slide bar 16 to move along the inner side of the support plate 9 through the vertical plate 10, and compresses the spring 2 17. Spring, when the top of the bottom plate 11 and the bottom of the pull block 13 are on the same horizontal line, the rebound force of the spring 2 17 is used to push the vertical plate 10 to reset, and the vertical plate 10 drives the top of the bottom plate 11 to contact the bottom of the pull block 13, and the electric telescopic rod 18 can push the support plate 9 to make the bottom plate 11 pull the pull block 13 to reset upward, so that the knocking tube 6 is away from the transmission gear body 4. As a result, the electric telescopic rod 18 drives the support plate 9 to move back and forth, and the knocking tube 6 can repeatedly and evenly elastically knock the transmission gear body 4, and install the transmission gear body 4 on the motor shaft of the motor body 3, thereby achieving the effect of smoothly and evenly installing the transmission gear.

[0038] Example 2: Please refer to Figure 1-Figure 6, this embodiment further explains the first embodiment. Both ends of the mounting plate 5 in the figure are rotatably installed with positioning nuts 30, and both sides of the slide 2 are provided with threads matching the positioning nuts 30, which is convenient for adjusting the height of the mounting plate 5. Two symmetrically distributed arc strips 31 are fixedly installed between the two support plates 9, which is convenient for the two support plates 9 to move up and down synchronously. The bottom plate 11 and the pressure plate 14 are fixedly connected to the side close to the vertical plate 10 with a slide bar 20 that slides through the support plate 9, which is convenient for the bottom plate 11 and the pressure plate 14 to move smoothly. The top of the adjusting rod 24 is fixedly connected with a handle 32, and the top of the slide 2 is annular, which is convenient for operating the adjusting rod 24.

[0039] In this embodiment: the user can rotate the positioning nut 30 to move the mounting plate 5 along the thread on the slide 2, and adjust the position of the mounting plate 5 to make the knocking tube 6 move upward synchronously, so that the user can place the motor body 3 on the device base 1, and rotate the positioning nut 30 again to make the bottom end of the adjusting rod 24 rest against the motor shaft of the motor body 3 to provide positioning for the motor shaft. When the support plate 9 moves, the arc-shaped bar 31 between the two support plates 9 can facilitate the two support plates 9 to keep in sync, and when the bottom plate 11 and the pressure plate 14 move, it can drive the slide bar 20 to move along the inner side of the vertical plate 10, thereby improving the stability of the bottom plate 11 and the pressure plate 14. The user can rotate and adjust the adjusting rod 24 through the handle 32.

[0040] Example 3: Please refer to Figure 7 and Figure 8 This embodiment further explains other embodiments. The placement component shown in the figure includes a placement ring 33 located at the top of the device base 1. The bottom of the placement ring 33 is fixedly connected with a plurality of support rods 34 that are evenly distributed and slide to the inside of the device base 1. A spring 35 is fixedly connected between the bottom of the placement ring 33 and the top of the device base 1 to provide support and cushioning for the bottom of the motor body 3. The top of the placement ring 33 and the side of the U-shaped clamping plate 29 close to the motor body 3 are both provided with a plurality of evenly distributed anti-slip rubber strips 8 to improve the firmness of the positioning of the motor body 3.

[0041] In this embodiment: the user can place the motor body 3 on the placement ring 33 to provide support for the bottom of the motor body 3, and when the motor body 3 is vibrated by the hammer, the spring three 35 can provide a buffer for the bottom of the motor body 3, and the U-shaped clamp 29 and the anti-slip rubber strip 8 on the placement ring 33 can improve the firmness of the motor body 3 when positioning to prevent slipping.
