[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0033] Example 1

[0034] Please refer to Figure 3-5 , a stent, comprising:

[0035] A supporting member 1, wherein the supporting member 1 is arranged in a horizontal direction, and one end surface of the supporting member 1 is a supporting surface;

[0036] Support member 2, support member 2 is arranged along the vertical direction, multiple support members 2 are arranged at intervals along the outer peripheral wall of the supporting member 1, and the supporting surface and multiple support members 2 form a placement area;

[0037] Fastener 3, at least one fastener 3 is connected to the support 2, the fastener 3 extends into the placement area, and the fastener 3 is used to limit the position of the workpiece.

[0038] As a further solution, the fastener 3 is a bolt. The bolt is connected to the support member 2 through a thread, and the bolt is rotated to adjust the length of the screw rod of the bolt extending into the placement area, so that quartz crucibles with different outer diameters can be fixed.

[0039] As a further solution, the end of the bolt in contact with the quartz crucible is spherical. With a spherical structure, the bolt and the quartz crucible are in point contact.

[0040] It should be noted that the fastener 3 can also be replaced by a buckle. However, when a buckle is used, quartz crucibles with different outer diameters need to be fixed by buckles of different specifications.

[0041] It should be noted that a plurality of fasteners 3 arranged along the same horizontal plane is considered as a group. To ensure the fixing effect, a plurality of groups of fasteners 3 may be arranged along the vertical direction.

[0042] As a further solution, the number of the support members 2 is 3 to 5, preferably 4.

[0043] It should be noted that the plurality of support members 2 are evenly distributed along the outer peripheral wall of the supporting member 1 .

[0044] As a further solution, the distance between the support member 2 and the horizontal support surface is smaller than the distance between the support member 1 and the horizontal support surface. In this way, a distance can be left between the bottom surface of the support member 1 and the horizontal support surface to ensure smooth flow of the corrosive liquid.

[0045] As a further option, it also includes:

[0046] The fixing member 6 is arranged in the horizontal direction. The fixing member 6 is detachably connected to the multiple supporting members 2. The fixing member 6 is located above the supporting member 1. The fixing member 6 is used to limit the relative positions between the multiple supporting members 2.

[0047] After the fixing member 6 is provided, the plurality of supporting members 2 can be installed and fixed by the fixing member 6 in cooperation with the supporting member 1. The fixing member 6 can be detachably connected by bolting or clamping (it can also be combined with a hinge structure to reduce the difficulty of assembly and disassembly). The fixing member 6 can also be fixed relative to the supporting member 2 by a latch.

[0048] Preferably, the fixing member 6 comprises a plurality of second mounting rods. The fixing member 6 adopts the second mounting rods, which can save materials and reduce the weight of the entire bracket.

[0049] Example 2

[0050] refer to Figure 4 , Figure 5 , the structure of the supporting member 1 of the utility model is described in detail.

[0051] The first solution is that the supporting member 1 adopts a plurality of first mounting rods 4 , and the plurality of first mounting rods 4 extend horizontally outwards from the center point of the supporting member 1 .

[0052] The second solution is: the supporting member 1 is a plate member, and a supporting rod 5 is arranged at the center of the supporting surface.

[0053] As a further solution, the end of the supporting rod 5 that contacts the quartz crucible is in a spherical crown shape.

[0054] Obviously, the supporting members 1 of the above two structures can be used for etching a quartz crucible with a spherical crown bottom, and can also be used for etching a flat-bottomed quartz crucible. However, when the first scheme etches a flat-bottomed quartz crucible, the supporting member 1 is in line contact with the quartz crucible (the supporting rod 5 in the second scheme can be set at the center point of the supporting member 1 for improvement. After the improvement, the flat-bottomed quartz crucible and the supporting member 1 are in point contact).

[0055] Example 3

[0056] Based on the same utility model concept, the utility model also provides a corrosion device, which includes the bracket provided by any of the above embodiments, that is, includes the technical features of the above bracket, and therefore has the beneficial effects of the above bracket. The similarities can be referred to the above description.

[0057] refer to Figure 1 , Figure 2 , the corrosion device includes:

[0058] The cylinder 7 has a drain pipe 8 at the bottom of the outer wall of the cylinder 7, and the drain pipe 8 is connected to the cylinder 7;

[0059] The aforementioned bracket is located inside the cylinder 7, and the bracket and the cylinder 7 are clearance-fitted.

[0060] Specifically, the bracket is placed into the cylinder 7, and then the quartz crucible is placed into the placement area with the opening facing upward, the quartz crucible is fixed by the fasteners 3 on each support 2, and then the drain pipe 8 is closed, and the etching liquid is injected until the etching liquid submerges the quartz crucible. After the etching is completed, the drain pipe 8 is opened, the etching liquid is discharged, and the inner wall of the cylinder 7 is cleaned with clean water.

[0061] As a further solution, a plurality of limiting grooves 9 are provided on the inner bottom surface of the cylinder 7 , and the limiting grooves 9 correspond to the supporting members 2 one by one, and the supporting members 2 can be inserted into the limiting grooves 9 .

[0062] Through this design, the position of the bracket can be fixed.

[0063] It should be noted that after the support member 2 is inserted into the limiting groove 9, there should be a gap between the bottom of the support member 1 and the inner bottom surface of the cylinder 7 to allow the corrosive liquid to pass through.

[0064] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
