[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The present invention provides a technical solution, a motor magnetic cylinder assembly that is easy to assemble, such as Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, it includes a magnetic cylinder lower part 1, and the magnetic cylinder lower part 1 includes an outer cylinder part 101 and an inner cylinder part 102. A special-shaped limiting groove 1012 is opened in the inner wall of the outer cylinder part 101, and a limiting through groove 1011 is opened on the outer cylinder part 101. A positioning bolt 1013 is installed on the inner wall of the outer cylinder part 101. The outer cylinder part 101 is fixedly connected to the outer wall of the inner cylinder part 102 through the positioning bolt 1013. A transmission gear 4 is rotatably sleeved on the positioning bolt 1013. A face gear ring 3 is provided in the lower part of the magnetic cylinder 1, and the width of the face gear ring 3 is equal to or greater than 0. The bottom side of the transmission gear 4 is in contact and meshing with the face gear ring 3, which is in contact and meshing with the special-shaped shifting rod 201 through the tooth groove 202, and the front and rear sides of the face gear ring 3 are connected with internal threaded columns 301, which are slidably connected with the limiting groove 1011. A threaded pressing sleeve 302 is sleeved on the internal threaded column 301, which is threadedly connected with the internal threaded column 301, and the inner end of the threaded pressing sleeve 302 is in contact and pressed with the outer cylinder 101;

[0026] like Figure 5 As shown, a magnetic cylinder top cover 2 is provided above the lower part 1 of the magnetic cylinder, and a special-shaped shift rod 201 is installed on the lower side of the magnetic cylinder top cover 2. A tooth groove 202 is provided on the lower side of the special-shaped shift rod 201, and a special-shaped limiting rod 203 is provided on the outer side of the special-shaped shift rod 201. The special-shaped shift rod 201 and the special-shaped limiting rod 203 have the same bevel angle, and the special-shaped limiting rod 203 is slidably engaged with the special-shaped limiting groove 1012. When the special-shaped limiting rod 203 is engaged with the special-shaped limiting groove 1012, the lower part 1 of the magnetic cylinder is engaged with the magnetic cylinder top cover 2.

[0027] The working principle of this device is as follows: inside the magnetic cylinder, an outer cylinder portion 101 and an inner cylinder portion 102 are provided in the lower portion 1 of the magnetic cylinder, and a face gear ring 3 is provided between the outer cylinder portion 101 and the inner cylinder portion 102. When the special-shaped limiting rod 203 on the magnetic cylinder top cover 2 is docked with the special-shaped limiting groove 1012, the face gear ring 3 is rotated through the internal thread column 301, and the face gear ring 3 drives the transmission gear 4 to rotate. Since the transmission gear 4 is engaged with the special-shaped shifting rod 201 through the tooth groove 202, the transmission gear 4 can drive the special-shaped shifting rod 201 and the magnetic cylinder top cover 2 to rotate downward under force, and the rotation direction is the docking track of the special-shaped limiting rod 203 and the special-shaped limiting groove 1012.

[0028] When the special-shaped limiting rod 203 engages with the special-shaped limiting groove 1012, the lower part 1 of the magnetic cylinder engages with the magnetic cylinder top cover 2, and then the outer wall of the outer cylinder part 101 is pressed and fixed by the threaded pressing sleeve 302. This structure facilitates the disassembly of the magnetic cylinder body and the maintenance of the interior.
