The top of the positioning seat 11 is fixedly mounted with a mounting seat 12, and the top of the mounting seat 12 is fixedly mounted with a screw 13.
[0027] The protective ring 2 is detachably sleeved on the mounting base 12. Its outer diameter is smaller than the inner diameter of the part 4, and the height of its top is higher than the height of the machined part of the part 4.
[0028] The pressure block 3 is threadedly connected to the screw 13 and is used to press and fix the part 4 and to limit the movement of the protective ring 2.
[0029] In this embodiment, when laser cutting the small hole on the outer periphery of part 4, firstly, the protective ring 2 is placed on the mounting base 12, and then part 4 is placed on the positioning base 11 to position it so that it is coaxial with the base 1; then the pressure block 3 is connected to the screw 13 and tightened to press and fix part 4, and limit the protective ring 2 so that it is always in the protective position, that is, blocked inside the small hole to be processed.
[0030] At this point, part 4 and the fixture are placed together on the laser cutting machine. The laser cutting machine clamps and fixes the base 1. After fixing, part 4 is coaxial with the base 1. The processing part can be accurately positioned through the base 1, ensuring accurate cutting of each small hole. During cutting, the protective ring 2 can effectively prevent molten slag from falling onto the inner surface of part 4, ensuring the processing quality of part 4. At the same time, it effectively avoids the risk of the laser penetrating the opposite hole and causing part 4 to be scrapped, ensuring the yield of part 4.

[0034] In a preferred embodiment, the protective ring 2 is made of stainless steel or aluminum alloy, which has high structural strength and long service life.
[0035] In a preferred embodiment, such as Figure 3 As shown, the pressure block 3 is cylindrical, and its outer diameter is not greater than the outer diameter of the part 4, but greater than the inner diameter of the part 4.
