[0028] Embodiment 1:

[0029] Please specifically refer to Figures 1-4 , an electric appliance cutter shaft. In this embodiment, the electric appliance is a wall breaker, and the cutter shaft body is adaptively installed on the wall breaker. The electric appliance cutter shaft includes: a cutter shaft body, a first connection structure is arranged on the outer wall of the cutter shaft body, the first connection structure is composed of a plurality of spirally arranged grooves, a connection part is arranged at one end of the cutter shaft body, and the width of the cutter shaft body is greater than the width of the connection part.

[0030] Furthermore, the cutter shaft body and the connection part are of an integral structure. The integral structure of the cutter shaft body and the connection part has higher strength and better stability.

[0031] In this embodiment, an external thread is provided on the outer wall of the connecting portion, and an internal thread adapted to the external thread is provided at the top of the transmission shaft of the driving device. The cutter shaft body is fixed on the transmission shaft through the cooperation of the threads.

[0032] In addition, the cutter shaft body and the connecting portion are of an integral hollow structure. Fasteners can be installed in the cutter shaft body and the connecting portion. A threaded structure is provided at the top of the transmission shaft of the driving device, that is, the cutter shaft can be fixed on the transmission shaft through the fasteners.

[0033] It further includes: an output member matching with the cutter shaft body. In this embodiment, the output member is a wall-breaking cutter group. The output member is sleeved on the cutter shaft body. An installation cavity is provided on the output member. The installation cavity penetrates one end face of the output member. A second connection structure is provided on the inner wall of the installation cavity. The second connection structure is composed of a plurality of convex ribs arranged in a spiral manner. The convex ribs are adapted to the groove body. The second connection structure is adapted to the first connection structure, that is, the rib direction of the second connection structure is the same as the groove body of the first connection structure. The output member is connected to the cutter shaft body through the cooperation of the first connection structure and the second connection structure.

[0034] In this embodiment, the first connection structure and the second connection structure are adapted spiral structures. Due to the special spiral structure, when installing the output member, only need to place the end face of the output member with the installation cavity on the top of the cutter shaft body, and the output member will rotate and descend automatically under its own gravity and the action of the spiral structure to complete the installation cooperation with the cutter shaft body.

[0035] Figure 3 If the direction of the groove body is clockwise from top to bottom, then as long as the rotation direction of the output member driven by the driving device is also clockwise, that is, the rotation direction of the output member is the same as the direction of the groove body, as Figure 3 、 4 shown, this can ensure that the output member will not fall off when the electrical appliance is working, and at the same time, the connection between the output member and the cutter shaft body will be closer during operation.

[0036] When it is necessary to disassemble the output member, just rotate the output member counterclockwise (opposite to the direction of the groove body), and the output member can be easily removed, which is convenient for cleaning the electrical appliance, the output member or replacing and repairing the output member.

[0037] Embodiment 2:

[0038] Please refer specifically to Figure 5 , the rest of this embodiment is the same as Embodiment 1. The difference is that the electrical appliance in this embodiment is a soybean milk machine, that is, the cutter shaft body is adaptively installed on the soybean milk machine for grinding soybeans.
