[0024] Optionally, a first opening 111 is provided on one side of the mounting groove 11, and the driving wheel 21 is partially located in the mounting groove 11 through the first opening 111; a second opening 112 is provided on the other side of the mounting groove 11, and the first gear 6 is partially located in the mounting groove 11 through the second opening 112. By providing the first opening 111, after the drive unit 2 and the driving wheel 21 are installed on the seat body 1, the side of the driving wheel 21 is located on one side of the mounting groove 11 through the first opening 111, so that after the mounting seat 4 is fixed in the mounting groove 11, the driven wheel 51 is just meshed with the driving wheel 21. By providing the second opening 112, after the first gear 6 is installed on the seat body 1, the side of the first gear 6 is located on the other side of the mounting groove 11 through the second opening 112, so that after the mounting seat 4 is fixed in the mounting groove 11, the second gear 52 is just meshed with the first gear 6.

[0025] In this example, a first mounting hole 113 is provided at the bottom of the mounting groove 11; a second mounting hole 41 is provided on the mounting seat 4, and the second mounting hole 41 is arranged opposite to the first mounting hole 113. By providing the second mounting hole 41 and the first mounting hole 113, during installation, the mounting seat 4 is placed in the mounting groove 11, so that the second mounting hole 41 is just aligned with the first mounting hole 113, and the driven wheel 51 is meshed with the driving wheel 21, and the second gear 52 is meshed with the first gear 6, and then a fixing member such as a screw is passed through the second mounting hole 41 and locked on the first mounting hole 113, so that the connection between the mounting seat 4 and the seat body 1 is completed, and the installation process is simple and convenient.

[0026] In a preferred embodiment of the utility model, it also includes a cover plate 7, which is locked on the base body 1 and covers the mounting groove 11. By setting the cover plate 7, after the mounting base 4 is fixed on the base body 1, the cover plate 7 is locked on the base body 1, thereby preventing the driven wheel 51 and the second gear 52 from being exposed to the outside world and preventing dust or debris from entering the mounting groove 11.

Among them, a locking plate 121 is provided in the clearance groove 12, and the locking plate 121 is tilted outward. Correspondingly, a connecting plate is provided on the drive unit 2. When installing the drive unit 2, the connecting plate is aligned with the locking plate 121, and then locked by screws, thereby completing the installation of the drive unit 2. The installation process of the drive unit 2 is relatively simple and the installation is relatively convenient.

[0033] In order to prevent dust and debris from entering the clearance groove 12 , in this example, a shell 8 is further included. The shell 8 is locked on the base 1 and covers the clearance groove 12 , thereby effectively preventing dust and debris from entering the clearance groove 12 .

[0034] Compared with the prior art, the utility model forms a mounting groove 11 by recessing the outside of the seat body 1 so that the notch of the mounting groove 11 faces outward. During installation, the mounting seat 4 can be directly set on the seat body 1 to complete the transmission connection between the drive unit 2 and the cutter disc 3. The installation process is simple and convenient, and the installation speed is fast.
