[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-6 As shown, an anti-falling combined sprocket group includes a mounting shaft 1, a sprocket 16 is sleeved on the outer end of the mounting shaft 1, a positioning groove 17 is opened in the sprocket 16, a positioning strip 2 is fixedly connected to the outer end of the mounting shaft 1, and the positioning strip 2 is inserted in the positioning groove 17, so that the installation of the sprocket 16 can be positioned, so that the sprocket 16 can only rotate with the mounting shaft 1, and no relative rotation occurs between the two. A locking block 3 is arranged in the positioning strip 2, and the locking block 3 includes a card plate 4, which is located at the upper end of the positioning strip 2 and cannot enter the positioning strip 2. An anti-skid groove is arranged on the upper end of the card plate 4, and an anti-skid groove is opened on the inner side of the positioning groove 17. The card plate 4 can be clamped in the positioning groove 17, and the anti-skid grooves of the two will be connected, thereby greatly increasing the friction between the two.

[0025] A spring 5 is fixedly connected to the lower end of the card plate 4, and a top block 6 is fixedly connected to the lower end of the spring 5. The top block 6 is slidably connected in the positioning strip 2. The top block 6 is used to support the spring 5. An anti-drop plate 7 is fixedly connected to the lower end of the top block 6. The anti-drop plate 7 is located in the installation shaft 1. Through the cooperation of the anti-drop plate 7 and the card plate 4, the locking block 3 will not fall off the installation shaft 1. A limiting plate 8 is fixedly connected to the lower end of the card plate 4. The spring 5 is located between the limiting plates 8. The limiting plates 8 are slidably connected in the positioning strip 2, which can ensure that the spring 5 will not tilt, thereby constraining the movement of the card plate 4 and preventing it from deflecting.

[0026] A fixing rod 9 is inserted into the mounting shaft 1, and the tail end of the fixing rod 9 is set to an inclined surface. The fixing rod 9 can contact the anti-dropping plate 7, and the inclined surface can lift the anti-dropping plate 7 without being hindered from moving by the anti-dropping plate 7. A threaded ring 10 is set at the side end of the mounting shaft 1, and a threaded head 11 is fixedly connected to the side end of the fixing rod 9. The threaded head 11 can be threadedly connected in the threaded ring 10 to fix the fixing rod 9. A rotating head 12 is fixedly connected to the side end of the threaded head 11, and the rotating head 12 can conveniently drive the fixing rod 9 to rotate.

The upper and lower ends of the threaded rod 20 are connected with a support plate 21, and the support plate 21 is used to support and connect the threaded rod 20 and the track rod. The upper end of the threaded rod 20 is fixedly connected to the rotating handle.

[0028] The sprocket 16 is sleeved on the outer end of the installation shaft 1, and the positioning strip 2 is inserted into the positioning groove 17 to determine the position of each sprocket 16. Then the fixing rod 9 is inserted into the installation shaft 1. The inclined surface of the side end of the fixing rod 9 will act on each locking block 3, which will lift the anti-slip plate 7, and the card plate 4 will be lifted by the top block 6 and the spring 5. After the locking block 3 located in the sprocket 16 touches the positioning groove 17, its spring 5 will be completely compressed, and the card plate 4 will be just clamped in the positioning groove 17. Under the action of elastic force, the sprocket 16 is fixed, and the locking block 3 that is not inside the sprocket 16, its clamping plate 4 is not blocked, so the spring 5 will not be compressed, so that the clamping plate 4 will protrude beyond the positioning groove 17, so that the two ends of the sprocket 16 can be limited and fixed. After the fixing rod 9 is inserted into the mounting shaft 1, the threaded head 11 is driven to rotate by the rotating head 12, so that it acts on the threaded ring 10, so that the threaded head 11 is threadedly connected in the threaded ring 10, so as to fix the fixing rod 9.
