The upper surface of the fixing plate 51 is provided with grooves and there are multiple groups of grooves. Multiple groups of grooves are provided to ensure that when fixing rubber rings of different sizes, they can cooperate with the limiting rod 52 to fix the rotating disk 57. The lower surface of the limiting rod 52 contacts the inner wall of the groove, and the outer wall of the limiting rod 52 is sleeved with a spring 53. When the limiting rod 52 is not pulled, the spring 53 always pulls the limiting rod 52 downward by its own elasticity to ensure the stability of the limit. One end of the spring 53 is fixedly connected to the lower surface of the limiting rod 52, and the other end of the spring 53 is fixedly connected to the upper surface of the connecting block 54.

[0034] Reference Figure 2 - Figure 3 A rectangular groove 85 is provided on the inner wall of the circular ring 81, and the arc-shaped block 84 slides on the inner wall of the rectangular groove 85. A spring 83 is sleeved on the outer wall of the pull rod 82. The spring 83 always pulls the pull rod 82 backward by its own elasticity to ensure the stability of the limit. One end of the spring 83 is fixedly connected to the rear surface of the pull rod 82, and the other end of the spring 83 is fixedly connected to the front surface of the circular ring 81.

[0035] Working principle: When fixing the rubber ring during use, it is only necessary to place the rubber ring on the upper surface of the light-transmitting plate 3 and place the multiple clamping rods 55 in the middle of the rubber ring. At this time, the limit rod 52 is pulled upward, and the limit rod 52 will stretch the spring 1 53 upward until the bottom end of the limit rod 52 is completely separated from the inner wall of the groove. At this time, the limit rod 52 can be used to push the connecting block 54 to move, and the connecting block 54 will drive the round rod 510 to slide on the inner wall of the through groove 1 56. The round rod 510 will drive the connecting plate 59 to slide on the inner wall of the through groove 4 7 along the curvature of the through groove 1 56, and the connecting plate 59 will slide on the inner wall of the through groove 4 7 along the curvature of the through groove 1 56. The plate 59 will drive the turntable 57 to rotate. At this time, the bottom end of the clamping rod 55 will slide on the inner wall of the through groove 2 58 and move on the inner wall of the through groove 3 6 along the curvature of the through groove 2 58. In this way, the multiple sets of clamping rods 55 can stretch and fix the rubber ring. After the fixation is completed, the limit rod 52 can be loosened. At this time, the spring 1 53 will pull the limit rod 52 downward through its own elasticity so that it can be inserted into the inner wall of the groove to limit the connecting block 54. At this time, the crack detection device 1 is started to irradiate the rubber ring with light through the light-transmitting plate 3 and the turntable 57, and the rubber ring can be detected through the lens 4.

[0036] When the lens 4 needs to be replaced, it is only necessary to pull the pull rod 82. The pull rod 82 will drive the arc block 84 to move while stretching the spring 2 83, so that it is separated from the upper surface of the lens 4. At this time, the lens 4 can be pushed out from the bottom of the ring 81 by hand. When installing, it is only necessary to directly put the lens 4 into the inner wall of the ring 81. The lens 4 will be pushed to move along the inclined surface of the arc block 84. The arc block 84 will enter the inner wall of the rectangular groove 85 and stretch the spring 2 83 through the pull rod 82 until the lens 4 moves to the bottom of the arc block 84. At this time, the spring 2 83 will drive the arc block 84 to move in the opposite direction through its own elasticity to reset, so that the lower surface of the arc block 84 contacts the upper surface of the lens 4, so that the lens 4 can be fixed. It is quick and convenient, and the work efficiency is improved.
