The fixing block 130 is connected to the thimble body 120, the convex block 140 is slidably connected to the fixing block 130, and the fixing block 130 is attached to the crystal edge protection ring body 110.
[0033] When specifically set, a slider 150 is arranged on the outer ring of the bump 140. A second sliding groove is formed on one side of the fixed block 130, and the slider 150 is slidably connected to the second sliding groove. Among them, by the sliding connection between the slider 150 and the second sliding groove, the movement of the bump 140 can be conveniently limited.
[0034] When specifically set, a limiting groove 160 is formed on one side of the main body 110 of the crystal edge protection ring. Among them, by forming the limiting groove 160 on one side of the main body 110 of the crystal edge protection ring, limiting can be facilitated and the main body 110 of the crystal edge protection ring can be prevented from shifting.
[0035] When specifically set, the top of the bump 140 is arc-shaped. Among them, by setting the top of the bump 140 to be arc-shaped, the limiting effect can be conveniently improved.
[0036] Please refer to Figure 1 、 Figure 3 and Figure 4 , the clamping structure 20 includes a clamping component 210 and a pulling block 220. The pulling block 220 is connected to the clamping component 210. The clamping component 210 is arranged in the fixed block 130, and the clamping component 210 is clamped with the bump 140.
[0037] When specifically set, the clamping component 210 includes a sliding rod 211, a limiting block 212 and a spring 213. The sliding rod 211 is connected to the pulling block 220. The sliding rod 211 is slidably connected to the fixed block 130. The sliding rod 211 is clamped with the bump 140. The limiting block 212 is connected to the sliding rod 211. The limiting block 212 is slidably connected to the fixed block 130. The spring 213 is sleeved on the sliding rod 211. Among them, through the arrangement of the sliding rod 211, the limiting block 212 and the spring 213, the bump 140 can be conveniently disassembled, assembled and replaced, and the use cost is reduced.
