[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0030] A shell connection method comprises the following steps:

[0031] 1) providing a cover plate, a side shell and a bottom shell; the side shell and the bottom shell have mutually fitting mounting inclined surfaces;

[0032] 2) The side shell and the bottom shell are fixedly connected at the installation inclined surface by screws;

[0033] 3) The cover plate is buckled onto the side shell and the bottom shell at the same time.

[0034] like Figures 1 to 12 As shown, the above connection method can be applied to a master hand tool, so that the shell connection structure of the master hand tool is simple and the installation operation is convenient. A master hand tool includes a shell 100 that can be connected to a master hand, and the shell 100 includes a master hand mounting portion 101, a cylindrical motor mounting portion 102, an upper cover plate 104, a side shell 105 and a bottom shell 103. The master hand mounting portion 101 and the side shell 105 are made in one piece. After the side shell 105 and the bottom shell 103 are fixedly connected, the upper cover plate 104 is buckled on the side shell 105 and the bottom shell 105.

[0035] The lower end of the motor mounting portion 102 is threadedly connected to the upper cover plate 104. The outer wall of the housing 100 is a smooth surface. The master hand mounting portion 101 of the master hand tool can be connected to the master hand 34.

[0036] The bottom shell 103 is provided with a first mounting bevel 103b at one end away from the motor mounting portion 102, and a first through hole 103d is provided on the first mounting bevel 103b. The lower part of the side shell 105 is provided with a second mounting bevel 105a which is in contact with the first mounting bevel 103b, and the bottom shell 103 is fixedly connected to the side shell 105 by a first fixing screw 33 passing through the first through hole 103d.

[0037] The bottom shell 103 is provided with a second through hole 103c, and the bottom end of the upper cover plate 104 is provided with a slot 104a, in which a self-locking nut 35 is provided. The self-locking nut 35 includes an embedding portion 35a that can be embedded in the slot 104a, and a nut mounting portion 35b that is integrally and vertically connected to the embedding portion 35a, and the screw hole 35b is provided in the middle of the nut mounting portion 35b. The second fixing screw 32 passes through the second through hole 103c and is connected to the self-locking nut 35. Therefore, the second screw 32 further fixes the bottom shell 102 and the upper cover plate 104. Through the design of the slot 104a and the self-locking nut 35, the housing is reliably fixed and the installation and disassembly of the motor are convenient.

[0038] The main hand mounting portion 101 and the side shell 105 are made in one piece, and the lower end of the motor mounting portion 102 is threadedly connected to the upper cover plate 104. The bottom shell 103 and the side shell 105 are fixed by the first fixing screw 33, and the lower end of the upper cover plate 104 is buckled with the upper ends of the bottom shell 103 and the side shell 105. The bottom shell 103 and the upper cover plate 104 can also be connected and reinforced by using the second fixing screw 32.

[0039] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
