[0020] See also Figures 1 to 3 The utility model is a structural view, a back structural view, and a cross-sectional view, which is a manual disassembly device for a motor coil, comprising a main body 1, the main body 1 comprising two parallel side walls, the side walls being connected to the side wall at the bottom through the vertical side walls, an ear plate 2 being arranged on the upper end surface of the main body 1, a hanging hole 3 being arranged on the end surface of the ear plate 2, the hanging hole 3 being used for hanging the device when not in use, for easy storage and arrangement, a sliding hole 4 being arranged on one end surface of the main body 1, a sliding sleeve 15 being connected to the edge of the sliding hole 4 and the inner side wall of the main body 1, a cutter 5 being slidingly arranged on the inner side of the sliding sleeve 15, a part of the sliding hole 4 extending downward at the normal state of the cutter 5, and the cutter 5 The tail of the body 1 is connected with a back plate 11, and a spring 16 is arranged between the back plate 11 and the side wall in the vertical direction of the main body 1. A limiting column is arranged on the end face of the back plate 11 on the side opposite to the side wall in the vertical direction of the main body 1, and a mounting column is arranged on the inner end face of the side wall in the vertical direction of the main body 1. A circular through hole is opened on the circumferential surface of the mounting column. One end of the spring 16 passes through the mounting column and the other end is arranged on the outside of the limiting column. When the back plate 11 is subjected to force to squeeze the spring 16, it will push the cutter 5 to slide outward and extend. Conversely, when the back plate 11 loses external force, the rebound force of the spring 16 when it is reset will cause the back plate 11 to slide into the main body 1 with the cutter 5.

[0021] A rotating bolt 6 is provided on the inner side of the main body 1 through a nut, a second push plate 13 is rotatably provided on the outer side of the rotating bolt 6 and on the inner side of the main body 1, a rotating shaft 7 is rotatably provided on the inner side of the main body 1 through a retaining spring 12, a first push plate 10 is provided on the outer side of the rotating shaft 7 and on the inner side of the main body 1, a first handle 9 is provided on the outer side of the end of the rotating shaft 7 through a mounting bolt 8, a second handle 14 is connected to the lower end of the main body 1, the rotating shaft 7 includes a first cylindrical section, a hexagonal section, and a second cylindrical section, the first cylindrical section is provided on the inner side of the side wall of the main body 1 close to the first handle 9, and the second cylindrical section is provided on the main body 1 away from the first handle 9 On the inner side of the side wall on one side, the hexagonal section is arranged on the inner side of the first push plate 10, and the first push plate 10 is provided with a hexagonal groove which is plugged into the hexagonal section, and the hexagonal groove and the hexagonal section are transitionally matched. An outer hexagonal end is provided at one end of the rotating shaft 7 close to the first handle 9, and the mounting bolt 8 is connected to the outer hexagonal end. The first handle 9 is provided with an inner hexagonal slot which is matched with the outer hexagonal end, and the inner hexagonal slot and the outer hexagonal end are transitionally matched. Under normal conditions, the first push plate 10, the second push plate 13, and the first handle 9 are all vertically arranged, and the length of the lower part of the first push plate 10 is longer than the upper part, with the connection with the rotating bolt 6 as the boundary.

[0022] The utility model adopts the lever principle to save labor. When in use, the device of the utility model needs to be inserted into the hollow space in the middle of the stator, and the outer shape contour of the right-angle slot set by the main body 1 is clamped on the side wall of the rotor, so that the cutter 5 is aligned with the connection part of the coil. The second handle 14 is held and the first handle 9 is manually operated to rotate in the direction away from the tip of the cutter 5. The power of the first handle 9 is transmitted to the connected first push plate 10 through the rotating shaft 7, and the first push plate 10 rotates together and touches the second push plate 13. In this process, the first handle 9 acts as a lever. The rotating shaft 7 is used as a fulcrum to save force for the first time. After the first push plate 10 touches the second push plate 13, the second push plate 13 is pushed to continue moving. Because the lower part of the second push plate 13 is longer than the upper part, the second push plate 13 is used as a lever at this time, and the rotating bolt 6 is used as a fulcrum to save force for the second time. The upper part of the second push plate 13 collides and pushes the back plate 11 due to the rotation, so that the back plate 11 squeezes the spring 16 and pushes the cutter 5 to extend outward to cut the target coil. The human hand withdraws the force on the first handle 9, the spring 16 rebounds and resets, and the cutter 5 will also reset with the back plate 11.

[0023] The utility model designs the device into a manual operation mode, and uses the lever principle to greatly reduce the manual operation effort. It has a small size and is easy to carry, and can be suitable for outdoor and mobile operations. It achieves the functions of simple structure and low cost, easy and efficient operation, and easy to carry.
