The sliding of the sliding block 13 in the sliding groove 15 can change the distance between the fixed transmission wheel 4 and the mobile transmission wheel 18, so as to facilitate matching of transmission belts of different models;
[0030] A cross cavity 11 is provided on one side of the fixed transmission wheel 4, and a cross core 9 matching the cross cavity 11 is provided on one side of the second right-angle tooth 7. The second right-angle tooth 7 of the cross core 9 is fixedly connected, and the width of the cross core 9 is smaller than the depth of the cross cavity 11. The cross core 9 can be extended and retracted inside the cross cavity 11 to ensure that the first right-angle tooth 6 is in close contact with the second right-angle tooth 7.
[0031] A spring 10 is arranged on the outside of the cross core 9, one end of the spring 10 is fixedly connected to the side of the second right-angle tooth 7, and the other end of the spring 10 is fixedly connected to the side of the fixed transmission wheel 4, and the inner diameter of the spring 10 is larger than the outer diameter of the cross core 9, and the spring 10 can squeeze the second right-angle tooth 7, so as to facilitate the use of the device;

[0034] Working principle: When in use, connect the driven gear 1 of the device with the gear on the car. When the driven gear 1 rotates, the first right-angle tooth 6 will drive the second right-angle tooth 7 to rotate. If the driven gear 1 stops, the bevel of the second right-angle tooth 7 will fit tightly against the bevel of the first right-angle tooth 6 and fall off. At this time, the second right-angle tooth 7 will move to one side, and the cross core 9 can be retracted inside the cross cavity 11, and the spring 10 will bounce the second right-angle tooth 7 back again, which can make the first right-angle tooth 6 slide on the second right-angle tooth 7. The first right-angle tooth 6 and the second right-angle tooth 7 can only rotate forward but not reverse. The fin 3 can fully increase the contact area with the air and slow down the overheating of the device.
