[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] like Figure 1-2 As shown, this embodiment provides a tool for assembling and disassembling the ring 300 on a frequency converter, including a handheld part 100 and a connector. The handheld part 100 is used for gripping, facilitating the application of force when assembling or disassembling the ring 300. The connector is fixed to the handheld part 100 and includes a connecting base and protrusions arranged around the connecting base. There are at least two protrusions, which are symmetrically distributed along the central axis of the connecting base. When the ring 300 is opened, each protrusion engages in a different notch 301 on the ring 300. The ring 300 can be rotated by engaging two symmetrically arranged protrusions in the notches 301.

[0023] See Figure 3The ring 300 is screwed onto the periphery of the regulating switch 310. The ring 300 has four notches 301 spaced apart, which extend vertically downward from the top of the ring 300. The mating joints can avoid the regulating switch 310. After the protrusion engages with the notch 301, the ring can be unscrewed by rotating the handle 100. After removing the ring, the regulating switch 310 can be easily operated.

[0024] In some embodiments, the connecting base is a sleeve 200, the inner diameter of which is larger than the outer diameter of the ring 300. The protrusion 210 is fixed to the inner side of the sleeve 200 and extends radially toward the center of the sleeve 200. In order to avoid the adjustment switch 310, the sleeve 200, whose inner diameter is larger than the outer diameter of the ring 300, can be directly fitted onto the outside of the ring 300, so that the protrusion 210 can be engaged into the notch 301.

[0025] In some embodiments, the connecting base is a column 400, the outer diameter of which is smaller than the inner diameter of the sleeve 300. The protrusion 210 is fixed to the outer side of the column 400 and extends radially outward along the column 400. The diameter of the column 400 is smaller than that of the sleeve 200, but it needs to be inserted into the inside of the sleeve 300 so that the protrusion 210 on the outer side of the column 400 can engage with the notch 301.

[0026] Furthermore, since the column 400 needs to be inserted into the loop 300, if the top of the adjusting switch 310 is flush with the loop 300, it will block the column 400 before the protrusion 210 engages with the notch 301. Therefore, a clearance cavity 420 is provided extending upwards from the bottom surface of the column 400. The clearance cavity 420 can accommodate the adjusting switch 310, ensuring that the column 400 does not interfere with the adjusting switch 310 when the protrusion 210 engages with the notch 301 of the loop 300. The handle 100 and the column 400 are coaxially connected.

[0027] In some embodiments, there are four bumps, which are evenly distributed around the base. The number of bumps corresponds one-to-one with the number of notches 301, so that the connector and the sleeve 300 have more contact points and the force is more evenly distributed when the connector is opened. The circumferential dimension of the bump is smaller than the width of the notch 301, thereby ensuring that the bump can be engaged with the notch 301.

[0028] In some embodiments, the bumps are distributed on the same circle. The loop 300 is circular, and the bumps distributed on the same circle can fit more smoothly with the notch 301 of the loop 300.

[0029] In some embodiments, the handle 100 is cylindrical, and the sleeve 200 is coaxially connected to the handle 100. Both the handle 100 and the sleeve 200 are hollow, making them lighter and more material-efficient. They can also be made of plastic. The handle 100 and the sleeve 200 can be integrally molded, or they can be joined and fixed together after each is molded.

[0030] In some embodiments, the diameter of the handle 100 is smaller than the diameter of the cylindrical part. A smaller diameter makes it easier to grip.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.
