A plurality of first bolts 3 are provided on the top of the top plate 2. The first bolts 3 pass through the top and are threadedly connected in the circular groove 101.

The staff turns the first bolt 3, and the first bolt 3 passes through the top plate 4 and is threadedly connected with the circular groove 101 on the top of the driving gear 1, so that the top plate 2 and the bottom plate 4 clamp the driven gear 7 and limit the driven gear 7 to prevent the driven gear 7 from positional deviation affecting the meshing transmission. This arrangement facilitates the limited transmission when the composite gear is meshed and connected with the driving gear 1.

[0035] When in use, a bottom plate 4 and a top plate 2 are respectively provided on the top and bottom sides of the driving gear 1, and the bottom plate 4 and the top plate 2 are used to limit the meshing driven gear 7 to ensure that the same driven gear 7 is at the same height as the driving gear 1, avoiding displacement of the position of the driven gear 7.

[0036] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: the staff rotates the first bolt 3 on one side of the driving gear 1 to mesh the driven gear 7 with the driving gear 1, and the spring 102 drives the top plate 2 to engage with the top of the driven gear 7 through its elastic performance. The staff rotates the first bolt 3, and the first bolt 3 penetrates the top plate 4 and is threadedly connected with the circular groove 101 at the top of the driving gear 1, so that the top plate 2 and the bottom plate 4 clamp the driven gear 7, and limit the driven gear 7 to avoid the position deviation of the driven gear 7 affecting the meshing transmission, and the setting is convenient for the composite gear to be limited when the driving gear 1 is meshed and connected. The existing shaft rods connected to the driving gear 1 and the driven gear 7 have different styles and sizes. In order to facilitate the adaptation and use of the driving gear 1, a threaded groove is opened on the outside of the axis groove 103 of the driving gear 1. The staff inserts the axis sleeves 6 of different styles into the axis groove 103, rotates the axis sleeve 6, and makes the axis sleeve 6 connected to the axis groove 103 by threads, which is convenient for the connection and use of various shaft rods.
