[0002] A motor is a device that converts electrical energy into mechanical energy. In a motor, current generates torque in a magnetic field, which drives the motor to rotate. A motor usually consists of a stator and a rotor, where the stator is a fixed part and the rotor can rotate. There are many types of motors, including DC motors, AC motors, stepper motors, etc.

[0003] In the existing technology, a variety of parts are required to assemble a motor, and the second one is the motor end cover.

[0026] In this embodiment, when the end cover body 114 is required to be clamped and fixed, the handle 18 is rotated so that the screw rod 17 is displaced after being affected, and the hollow cylinder 13 is driven to move in the direction of the end cover. When it moves to a certain extent, the connecting rod 15 will contact the end cover body 114 and pass through the middle end of the end cover body 114. After passing through, the spring 16 will be released without external force, and the end positions of the three connecting rods 15 will be transformed from the reduced form to the expanded state, and the connecting rods 15 will be connected to the end cover body 114. The rock wall of the rod 15 fits with one side of the end cover body 114. At this time, since the end cover body 114 is buckled inside the connecting frame 23 and is not fixed, it is only necessary to rotate the handle 18 in the opposite direction to make the hollow cylinder 13 move in the opposite direction, and the connecting rod 15 will move in the same way and drag the end cover body 114 to one side.

[0027] Secondly, if it is necessary to release the restriction on the end cover body 114, it is only necessary to rotate the screw rod 112 to displace the ring 111 in the hollow cylinder 13. During the displacement, it will come into contact with the triangle plate 110. When it reaches the commanding height of the triangle plate 110, the positions of the ends of the three connecting rods 15 will shrink, thereby releasing the fixation of the end cover body 114. The commanding height of the triangle plate 110 is used to trigger the shrinkage of the positions of the ends of the connecting rods 15, ensuring the stability and reliability of the release of the fixation and avoiding accidental loosening or failure. The whole process is fast and efficient, saving time and energy.

When it moves to a certain extent, the connecting rod 15 will contact the end cover body 114 and pass through the middle end of the end cover body 114. After passing through, the spring 16 will be released without external force, and the end positions of the three connecting rods 15 will be transformed from a reduced form to an expanded state, and the rock wall of the connecting rod 15 will fit with one side of the end cover body 114. At this time, since the end cover body 114 is buckled in the interior of the connecting frame 23 and is not fixed, it is only necessary to rotate the turning handle 18 in the opposite direction to make the hollow cylinder 13 move in the opposite direction, and the connecting rod 15 will move in the same way and drag the end cover body 114 to one side. At the same time, under the action of the connecting frame 23 as a supporting point, mutual reverse pulling is formed, which is suitable for frequent clamping operations.
