[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution comprising: a fixing mechanism 1 and a metal ring mechanism 2. The fixing mechanism 1 includes an upper fixing frame 101, a first positioning groove 102, a first positioning hole 103, a first anti-slip ring 104, a first positioning block 105, a lower fixing frame 106, a second positioning groove 107, a second positioning hole 108, a second anti-slip ring 109, a second positioning block 110, a bolt 111, and a nut 112. The fixing mechanism 1 is internally provided with a metal ring mechanism 2, which includes a first metal ring 201, a placement groove 202, and a second metal ring 203.

[0025] In one embodiment, the bottom of the upper fixed frame 101 is provided with a first positioning groove 102, and the top of the first positioning groove 102 is provided with a first positioning hole 103. The inner wall of the first positioning groove 102 is movably connected to the outer wall of the first positioning hole 103. The top of the first positioning hole 103 is fixedly connected to the bottom of the first anti-slip ring 104. The outer wall of the first anti-slip ring 104 is movably connected to the inner wall of the first positioning hole 103. The bottom of the upper fixed frame 101 is movably connected to the top of the lower fixed frame 106. The top of the lower fixed frame 106 is provided with a second positioning groove 107. The inner wall of the second positioning groove 107 is provided with a second positioning hole 108. The inner wall of the second positioning groove 107 is movably connected to the outer wall of the second anti-slip ring 109. The bottom of the second anti-slip ring 109 is fixedly connected to the top of the second positioning block 110. The outer wall of the second positioning block 110 is movably connected to the inner wall of the second positioning hole 108.

[0026] Specifically: When the first anti-slip ring 104 and the second anti-slip ring 109 are damaged due to prolonged pressure, the first anti-slip ring 104 and the second anti-slip ring 109 can be removed through the movable connection of the first positioning block 105 and the first positioning hole 103, and the movable connection of the second positioning block 110 and the second positioning hole 108. The setting of the first anti-slip ring 104 and the second anti-slip ring 109 makes the two ends of the second metal ring 203 subject to rigid pressure, thereby increasing the protection effect on the compressed surfaces of the second metal ring 203.

[0027] In one embodiment, the inner walls of the upper fixing frame 101 and the lower fixing frame 106 are movably connected to the outer wall of the bolt 111, and the top outer wall of the bolt 111 is threadedly connected to the inner wall of the nut 112. Rotating the nut 112 causes the upper fixing frame 101 and the lower fixing frame 106 to press the two ends of the second metal ring 203, thereby stabilizing the first metal ring 201 and the second metal ring 203. This facilitates the fixing of the first metal ring 201 and the second metal ring 203, reduces the deformation and instability that occur during laser welding of the first metal ring 201 and the second metal ring 203, and increases the welding effect.

[0028] The upper fixing frame 101 and the lower fixing frame 106 are connected by bolts 111, so that the upper fixing frame 101 and the lower fixing frame 106 are modularly set, which facilitates the replacement of the upper fixing frame 101 and the lower fixing frame 106. In one embodiment, the bottom of the first metal ring 201 is provided with a placement groove 202, and the inner wall of the placement groove 202 is movably connected to the bottom outer wall of the second metal ring 203.

[0029] Specifically: First, the second metal ring 203 is placed inside the first metal ring 201, and the combination of the first metal ring 201 and the second metal ring 203 is completed by positioning through the placement groove 202.

[0030] Working principle: First, the second metal ring 203 is placed inside the first metal ring 201. Positioned by the placement groove 202, the first metal ring 201 and the second metal ring 203 are combined. The second metal ring 203 is then placed between the upper fixing bracket 101 and the lower fixing bracket 106, so that the top of the second metal ring 203 enters the first positioning groove 102 and simultaneously contacts the bottom of the first anti-slip ring 104. Simultaneously, the bottom of the second metal ring 203 enters the second positioning groove 107 and simultaneously contacts the top of the second anti-slip ring 109. The bolt 111 passes through the upper fixing bracket. Inside the fixed frame 101 and the lower fixed frame 106, the nut 112 is rotated to cause the upper fixed frame 101 and the lower fixed frame 106 to press the two ends of the second metal ring 203, thereby stabilizing the first metal ring 201 and the second metal ring 203. When the first anti-slip ring 104 and the second anti-slip ring 109 are damaged due to prolonged pressure, the first anti-slip ring 104 and the second anti-slip ring 109 can be removed through the movable connection of the first positioning block 105 and the first positioning hole 103, and the movable connection of the second positioning block 110 and the second positioning hole 108.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
