Patent publication number CN212536586U discloses a new type of stepped gear shaft with high toughness in the technical field of stepped gear shafts. The utility model is provided with a reinforcing bracket, which forms a triangular structure support between the main shaft and the connecting shaft to improve the overall strength and toughness of the stepped gear shaft. Graphene layers are provided on the outer walls of the main shaft and the connecting shaft to improve the wear resistance and toughness of the stepped gear shaft. At the same time, the shaft body is made of a mixture of metal materials, and fine-grained metal carbides, tempered troostite and martensite are mixed in the manufacturing material to improve the overall strength, hardness and tensile strength of the shaft body, thereby making the overall strength and toughness of the stepped gear shaft higher.

[0025] In the above embodiment, it should be noted that the top of the rotating rod 301 is provided with a hexagonal groove so that an existing hexagonal wrench can be inserted therein to drive the rotating rod 301 to rotate and achieve the purpose of transmission.

[0026] The technical effect achieved by the above embodiment is as follows: the triangular plate 305 is movably sleeved inside the sliding groove 102, and its side close to the snap assembly 306 is fitted against the outer wall of the gear 2, so that when the fixed snap connection is completed, the snap assembly 306 can be used to clamp the gear 2 on both sides to prevent it from sliding on the surface of the gear shaft body 1, while also achieving the purpose of synchronization. The limiting ring 303 is rotatably installed inside the limiting groove 104 to ensure that the rotating rod 301 as a whole can only rotate in place without position displacement, thereby achieving the purpose of limiting.

[0027] Example 2

[0028] like Figure 1 and Figure 5 As shown, a new type of gear shaft includes all the contents of Example 1. In addition, the buckle assembly 306 includes a mounting box 3061, a guide column 3062 is fixedly installed inside the mounting box 3061, a spring 3063 is movably sleeved on the surface of the guide column 3062, the top of the spring 3063 is fixedly connected to a buckle block 3064, the bottom end of the spring 3063 is fixedly connected to the inside of the mounting box 3061, a guide groove 3065 is opened at the bottom end of the buckle block 3064, the top of the guide groove 3065 is set as a rounded structure, the buckle block 3064 is movably sleeved on the surface of the guide column 3062 through the guide groove 3065, the outer wall of the mounting box 3061 is attached to the inner wall of the mounting groove 101, and a buckle groove 201 is opened on the surface of the gear 2, and the size of the buckle groove 201 is adapted to the size of the buckle block 3064.

[0029] The technical effect achieved by the above embodiment is: the rounded corner structure can ensure that when it rotates, it is easy to cooperate with the gear 2 to press itself down, and then drive the spring 3063 to be compressed, so as to achieve the purpose of separating the gear 2 and the gear shaft body 1, and the guide column 3062 and the guide groove 3065 are cooperated to achieve the relative movement of the overall position of the snap block 3064, and no other actions except up and down movement will occur, which is convenient for operation during disassembly and assembly.

[0030] Working principle: When the gear 2 is worn and needs to be replaced, the protective cap 4 is pulled out, and the existing hexagonal wrench is used to drive the rotating rod 301 to rotate, so that the right-angle plate 304 moves toward each other, and then the triangular plate 305 enters the interior of the sliding groove 102 and disengages from the side of the gear 2. Then the mounting box 3061 will also descend, and at the same time, the snap block 3064 will also descend a distance. Then the gear 2 is rotated, so that the snap groove 201 puts pressure on the rounded corner of the snap block 3064, driving it to compress the spring 3063, so that it enters the interior of the mounting box 3061 and disengages from the snap groove 201, thereby realizing the separation of the two.
