[0007] Furthermore, the movable tooth is provided with a mating groove, and the transmission rib is engaged in the mating groove and drives the movable tooth to move.

[0008] Furthermore, the interior of the housing is also provided with a first washer and a second washer mounted on the drive shaft for limiting the fixed tooth, and the fixed tooth is provided between the first washer and the second washer.

[0009] Furthermore, one side of the second gasket abuts against the transmission rib, and one side of the first gasket abuts against the outer casing.

[0010] Furthermore, the fixed teeth are also engaged with a power transmission shaft rotatably connected to the housing.

[0011] Beneficial effects

[0012] Compared with the prior art, this utility model has the following advantages: the moving teeth are guided by the transmission ribs, so that the moving teeth are more clearly oriented during the biting process, and the engagement and disengagement are more stable. At the same time, the overall structure is compact and consumes less power. Attached Figure Description

[0021] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:

[0022] have Figures 1-6 As shown, this utility model discloses a toothed structure for a mechanical clutch transmission shaft, including a fixed tooth 2, which is rotatably connected to the transmission shaft 1. A movable tooth 3 capable of meshing with the fixed tooth 2 is also provided on one side of the fixed tooth 2. The movable tooth 3 can slide axially on the transmission shaft 1 under the drive of the control lever 4. A transmission rib 5 is fixedly provided on the transmission shaft 1, and the transmission rib 5 restricts the relative rotation between the transmission shaft 1 and the movable tooth 3.

[0023] Furthermore, the drive shaft 1 passes through and is rotatably connected to the housing 12, and a control shaft 9 is inserted into and rotatably connected to the inside of the housing 12. A paddle mounting groove 11 is provided in the control shaft 9, and a control paddle 4 is inserted into the paddle mounting groove 11.

[0024] Furthermore, the movable tooth 3 is provided with a mating groove 10, and the transmission rib 5 is engaged in the mating groove 10 and drives the movable tooth 3 to move.

[0025] Furthermore, the interior of the outer casing 12 is also provided with a first washer 6 and a second washer 7 mounted on the drive shaft 1 for limiting the fixed tooth 2, and the fixed tooth 2 is provided between the first washer 6 and the second washer 7.

[0026] Furthermore, one side of the second gasket 7 abuts against the transmission rib 5, and one side of the first gasket 6 abuts against the outer shell 12.

[0027] Furthermore, the fixed tooth 2 is also engaged with a power transmission shaft 8 that is rotatably connected to the housing 12.

[0028] Specifically, when clutch control is required, the control shaft 9 is rotated and the control paddle 4 is moved, which causes the movable tooth 3 to move left and right on the transmission shaft 1. When the movable tooth 3 moves to the left, it engages with the fixed tooth 2, and power transmission is achieved. When the movable tooth 3 moves to the right, it disengages from the fixed tooth 2, and power is stopped.

[0029] Used to achieve power clutch between drive shaft 1 and power transmission shaft 8.
