[0026] The top of the threaded block 8 is fixedly connected to a support rod 9 by bolt connection, and the support rod 9 is designed in an inverted "L" shape. The top of the support rod 9 is fixedly connected to a connecting block 26 by welding, and the connecting block 26 is designed in an inverted "L" shape. A No. 1 sliding groove 15 is provided at the top of the support rod 9 and the bottom of the connecting block 26. A sliding block 16 is slidably connected inside the No. 1 sliding groove 15, and the sliding block 16 is designed in a "C" shape.

A telescopic component is provided at the rear end of the sliding block 16, and the telescopic component is used to observe the internal protrusion of the tire;

[0027] During operation, the tire is first placed on the top of the lifting platform 6. At this time, the rotating plate 5 can be rotated to drive the rotating rod 4 to rotate, so that the rotating rod 4 drives the threaded block 8 to move outside the threaded groove 7, so that the support rod 9 and the connecting block 26 are supported on the inner wall of the tire. At this time, the No. 2 rotating wheel 18 will fit with the inner wall of the tire, so that the No. 2 rotating wheel 18 can rotate outside the No. 2 support shaft 17. If a cavity appears on the inner wall of the tire to produce a bulge, it will push the sliding block 16 to slide inside the No. 1 sliding groove 15. At this time, observing the telescopic assembly can find out where the cavity is generated. Detection by this method solves the problem of unclear marking at the detection point in the past and improves the accuracy of marking the cavity position.

[0029] During operation, when a bulge appears on the inner wall of the tire, it will push the No. 2 rotating wheel 18, the No. 2 supporting shaft 17 and the sliding block 16 to retract inward, thereby allowing the No. 2 spring 23 to retract. The length of the sliding rod 22 retracted into the hollow tube 21 can be used to observe the size of the cavity, thereby achieving the effect of being able to detect smaller cavities, solving the problem of inconvenient observation of smaller cavities in the past, and improving the accuracy of observation marks.

[0030] Further, such as Figure 3 and Figure 4 As shown, the support rod 9 is fixedly connected to the No. 1 support shaft 10 by welding on the side close to the No. 1 sliding groove 15, and the No. 1 support shaft 10 is slidably connected to the No. 1 rotating wheel 13 on the outside through a bearing, and the No. 1 support shaft 10 is fixedly connected to the limiting block 14 on the side away from the support rod 9 by bolt connection, and there is a gap between the No. 1 rotating wheel 13 and the support rod 9 at the "L"-shaped position, and the No. 1 rotating wheel 13 is provided with an elastic component on the side close to the support rod 9, and the elastic component is used to fit the outer wall of the tire;

[0031] During operation, the bottom of the tire can be inserted between the No. 1 rotating wheel 13 and the support rod 9. At this time, the No. 1 spring 11 will push the engaging shaft 12 and the No. 1 rotating wheel 13 to fit the outer wall of the tire. At this time, the tire rotates the No. 1 rotating wheel 13 to reduce friction. In this way, double support and fixation are achieved, a more stable fixation is achieved, the problem of movement of the No. 2 rotating wheel 18 caused by external offset is solved, and the stability of detection is improved.

[0032] Further, such as Figure 3 and Figure 4 As shown, the elastic assembly includes an embedded shaft 12, the embedded shaft 12 is rotatably connected to the inner side of the No. 1 rotating wheel 13 close to the support rod 9, the end of the embedded shaft 12 away from the No. 1 rotating wheel 13 is fixedly connected to the No. 1 spring 11 through an adhesive, the end of the No. 1 spring 11 away from the embedded shaft 12 is fixedly connected to the side of the support rod 9 through an adhesive, and the No. 1 spring 11 is arranged outside the No. 1 support shaft 10;

[0033] During operation, the interlocking shaft 12 can support the number one rotating wheel 13 to rotate outside the number one supporting shaft 10 and the interlocking shaft 12. At this time, the number one spring 11 can also push the number one rotating wheel 13 to adapt to the outer wall of the tire to rotate the tire.

A marking block 20 is slidably connected inside the second sliding groove 19, and the bottom of the marking block 20 is fixedly connected to the top of the sliding block 16 by bolt connection. A measuring component is provided in front of the marking block 20, and the measuring component is used to observe the bulge degree of the inner wall of the tire;

[0035] During operation, it is inconvenient to observe when the sliding rod 22 is retracted, so the marking block 20 slides inside the second sliding groove 19, so that the inner wall of the tire can be observed more accurately.

[0036] Further, such as Figure 1 and Figure 2 As shown, the observation assembly includes a fitting block 24, which is slidably connected to the inside of the connection block 26 near the front end, and a scale 25 is fixedly connected to the top of the fitting block 24 by an adhesive, and a scale mark is opened at the front end of the scale 25;

[0037] During operation, the engagement block 24 corresponds to the scale 25 and the scale marks thereof are observed more accurately, so that the cavity position of the tire is punctured.

[0038] The working principle is that the tire is first placed on the top of the lifting platform 6. At this time, the rotating plate 5 can be rotated to drive the rotating rod 4 to rotate, so that the rotating rod 4 drives the threaded block 8 to move outside the threaded groove 7, so that the support rod 9 and the connecting block 26 are supported on the inner wall of the tire. At this time, the No. 2 rotating wheel 18 will fit with the inner wall of the tire, so that the No. 2 rotating wheel 18 can rotate outside the No. 2 support shaft 17. If a cavity or bulge appears on the inner wall of the tire, it will push the sliding block 16 to slide inside the No. 1 sliding groove 15. At this time, observing the telescopic component can find out where the cavity is generated. Detection in this way solves the problem of unclear marking at the detection point in the past, and improves the accuracy of marking the cavity position. When a bulge appears on the inner wall of the tire, it will push the No. 2 rotating wheel 18, the No. 2 support shaft 17 and the sliding block 16 to retract inward, so that the No. 2 spring 23 retracts, and the length of the sliding rod 22 retracted into the hollow tube 21 can observe the size of the cavity, so that the smaller cavity can also be detected, which solves the problem of unclear marking at the detection point in the past. The problem of inconvenient observation of smaller cavities is solved, and the accuracy of observation marking is improved. The bottom of the tire can be inserted between the No. 1 rotating wheel 13 and the support rod 9. At this time, the No. 1 spring 11 will push the embedded shaft 12 and the No. 1 rotating wheel 13 to fit with the outer wall of the tire. At this time, the tire rotates the No. 1 rotating wheel 13 to reduce friction. In this way, double support and fixation are achieved, and more stable fixation is achieved. The problem of external offset causing the No. 2 rotating wheel 18 to move is solved, and the stability of detection is improved. The embedded shaft 12 can support the No. 1 rotating wheel 13 to rotate outside the No. 1 support shaft 10 and the embedded shaft 12. At this time, the No. 1 spring 11 can also push the No. 1 rotating wheel 13 to fit with the outer wall of the tire to rotate the tire. When the sliding rod 22 is contracted, it is inconvenient to observe. Therefore, the marking block 20 slides inside the No. 2 sliding groove 19, so that the inner wall of the tire can be observed more accurately. The embedding block 24 corresponds to the scale 25 and its scale mark is observed more accurately, so that the cavity position of the tire is punctured.
