[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides a technical solution: it includes a clutch drive device 1 and a bridge wheel 2, a protective component is arranged on the bridge wheel 2, the protective component includes a connecting block 3 and a docking block 4, both lower ends of the connecting block 3 and both upper ends of the docking block 4 are provided with mounting grooves 5, the mounting grooves 5 are adapted to the clutch drive device 1, the connecting block 3 and the docking block 4 are respectively clamped on the upper and lower sides of the bridge wheel 2, a wear-resistant sleeve 12 is arranged in the middle of the connecting block 3 and the docking block 4, and the wear-resistant sleeve 12 has the same texture as the bridge wheel 2.

[0023] By adopting the above design, when the bridge wheel 2 is used for transmission, the wear-resistant sleeve 12 between the connecting block 3 and the docking block 4 can replace the bridge wheel 2 for contact transmission, so that the surface of the bridge wheel 2 no longer contacts other components, and thus the bridge wheel 2 does not need to bear the transmission work. After the wear-resistant sleeve 12 is worn, the connecting block 3 and the docking block 4 can be separated up and down for quick replacement, thereby reducing the later maintenance cost of the device.

[0024] A slide groove 6 is provided in the connecting block 3, a slider 7 is slidably connected in the slide groove 6, a latch 8 is provided below the slider 7, a slot 9 is provided on the top surface of the docking block 4, the latch 8 is adapted to the slot 9, a connecting groove is provided on the side of the connecting block 3, a lever 10 is slidably connected in the connecting groove, and one side of the lever 10 is fixedly connected to the slider 7.

[0025] By adopting the above design, after installation, the latch 8 can be clamped in the slot 9 by pushing the lever 10, so that the connecting block 3 and the docking block 4 will not be separated without human interference, making the operation of the device more stable, and the centrifugal force generated by the bridge wheel 2 during rotation will only push the latch 8 toward the side wall of the slot 9, and will not cause the latch 8 to move in the opposite direction and cause it to separate.

[0026] Furthermore, there are two slide grooves 6, which are conveniently arranged on the left and right sides of the front and rear ends of the connecting block 3. The docking block 4 also has two slots 9, and their positions correspond.

[0027] By adopting the above design, the connecting block 3 and the docking block 4 can be fixed from different positions on both sides after installation, thereby making the installation of the connecting block 3 and the docking block 4 more stable.

[0028] Furthermore, an extension groove is provided on one side of the slide groove 6, one end of a spring 11 is fixedly connected in the extension groove, the other end of the spring 11 is fixedly connected to the slider 7, and a chamfer is provided on the end of the latch 8 near the docking block 4.

[0029] By adopting the above design, during installation, the connecting block 3 can be directly pressed toward the docking block 4, and the pin 8 will automatically retract along the chamfer. At this time, the spring 11 will deform and accumulate elastic potential energy until the pin 8 completely enters the slot 9. The spring 11 converts the elastic potential energy previously accumulated into kinetic energy, driving the pin 8 to reset and engage, thereby quickly completing the installation.

[0030] Working principle:

[0031] When in use, first fit the docking block 4 under the bridge wheel 2, and then press the connecting block 3 downward from the top. The pin 8 will automatically retract along the chamfer. At this time, the spring 11 will deform and accumulate elastic potential energy until the pin 8 completely enters the slot 9. The spring 11 converts the elastic potential energy previously accumulated into kinetic energy, driving the pin 8 to reset and engage, thereby quickly completing the installation.

[0032] When in use, the wear-resistant sleeve 12 between the connecting block 3 and the docking block 4 can replace the bridge wheel 2 for contact transmission, so that the surface of the bridge wheel 2 no longer contacts other components, and thus the bridge wheel 2 does not need to bear the transmission work. After the wear-resistant sleeve 12 is worn, the connecting block 3 and the docking block 4 can be separated up and down for quick replacement, thereby reducing the later maintenance cost of the device.
