The housing 101 is mounted on the motor plate 104 through the mounting plate 105. The motor plate 104 is a prior art. The motor plate 104 is used in conjunction with the motor and is a circuit that enables the motor to operate normally. The number of the plug-in components is two groups. The two groups of plug-in components are respectively arranged on both sides of the upper surface of the motor plate 104. The plug-in components form a right opening and a top opening on the motor plate 104. The two sides of the lower surface of the mounting plate 105 are respectively connected to the two groups of plug-in components, so that the mounting plate 105 can be inserted from the right side of the motor plate 104 into the inside of the motor plate 104 through the plug-in components, thereby the housing 10 1 is installed, the positioning component is arranged on the left side of the upper surface of the motor plate 104, and when the mounting plate 105 is fully inserted into the motor plate 104 through the plug-in component, the left side of the housing 101 abuts against the positioning component and generates mutual attraction, so that the housing 101 is fixed. When the housing 101 needs to be disassembled, a pulling force greater than the attraction between the housing 101 and the positioning component is applied to the housing 101, so that the plug-in component under the mounting plate 105 can be removed from the motor plate 104, which plays a role in quick removal. The function of quick disassembly is that after the motor shaft is installed, the mounting plate 105 at the bottom of the shell 101 is inserted from the right opening of the motor plate 104 through the plug-in component until the left side of the shell 101 abuts against the positioning component and generates mutual attraction, so that the shell 101 can maintain a stable state after being installed on the motor plate 104. The setting of the plug-in component also facilitates the disassembly of the shell 101, making it easy to install and disassemble the shell 101 on the motor plate 104, thereby improving work efficiency.

The cross-sectional dimensions of the sliding block 107 are matched with those of the plug-in rail 106, so that the sliding block 107 can be inserted from the right opening of the plug-in rail 106 and move in the plug-in rail 106. The connecting member is arranged on the upper surface of the sliding block 107, and the two sides of the lower surface of the mounting plate 105 are respectively connected with two groups of the connecting members, so that when the sliding block 107 moves in the plug-in rail 106, the mounting plate 105 can be installed and removed through the connecting member, thereby installing and removing the shell 101 on the motor plate 104.

[0025] At the same time, the connecting shaft 108 is fixedly connected to the sliding block 107 and is located on one side of the sliding block 107; the limiting baffle 109 is fixedly connected to the plug-in rail 106 and is located on one side of the plug-in rail 106. The number of the limiting baffles 109 is twice the number of the plug-in rails 106. Every two limiting baffles 109 form a group and are respectively welded on both sides of the top opening of the plug-in rail 106. The setting of the plug-in rail 106 makes the top opening size of the plug-in rail 106 smaller than the internal size of the plug-in rail 106, so that the sliding block 107 is located on the limiting baffle 109. Under the limiting effect, it will not detach from the plug-in rail 106 from the top of the plug-in rail 106. The number of the connecting shafts 108 corresponds to the number of the sliding blocks 107. The connecting shafts 108 are fixed to the upper surface of the sliding block 107, and the connecting shafts 108 just extend from between the two limit baffles 109 and are welded to the mounting plate 105, so that when the sliding block 107 moves in the plug-in rail 106, the mounting plate 105 can be driven by the connecting shaft 108 to move on the motor plate 104, thereby installing the housing 101 on the mounting plate 105.

After installation, the housing 101 can generate mutual attraction with the positioning plate 110 through the fixing member, so that the housing 101 maintains a stable state above the motor plate 104. There are two small fans 111, which are respectively fixed at two ends of the right side of the positioning plate 110. The air outlet of the small fan 111 faces one side of the housing 101, so that after starting the small fan 111, the small fan 111 can generate wind force in the direction of the housing 101, thereby playing a role in heat dissipation and cooling the motor shaft, thereby improving the service life of the motor shaft.

[0027] When using a permanent magnet motor shaft that can be connected in multiple ways according to the present embodiment, after the motor shaft is installed, the mounting plate 105 at the bottom of the housing 101 is inserted from the right side of the plug-in rail 106 through the sliding block 107 under the action of the connecting shaft 108, so that the mounting plate 105 moves to the left on the motor plate 104 until the left side of the housing 101 abuts against the positioning plate 110 through the fixing member and generates mutual attraction, so that the housing 101 can be installed on the motor plate 104. Maintaining a stable state, when the shell 101 needs to be disassembled, a pulling force greater than the attraction between the shell 101 and the positioning plate 110 is applied to the shell 101, and the sliding block 107 under the mounting plate 105 can be pulled out to the right from the plug-in rail 106, so that the mounting plate 105 drives the shell 101 to move out toward the right side of the motor plate 104, which plays a role in quick disassembly, making it easy to install and disassemble the shell 101 on the motor plate 104, thereby improving work efficiency.
