The upper and lower surfaces of the external seal body 1 are magnetically connected with an upper heightening gasket 26 and a lower thickening gasket 27. The internal seal body 25 can move up and down on the inside of the external seal body 1, and can quickly mark two specifications of sample blocks, greatly reducing the time of manual operation, and can also improve the accuracy of marking and reduce human errors.

[0028] Furthermore, a positioning structure 3 is installed on the external seal body 1, and the positioning structure 3 includes a fixed block 31, which is fixedly installed on the surface of the external seal body 1. A movable groove 32 is provided on the inner wall of the fixed block 31, and a positioning block 33 is movably installed on the inner side of the fixed block 31. A guide block 34 is integrally formed on the surface of the positioning block 33, and a spring 35 is fixedly connected to the top surface of the positioning block 33. The positioning block 33 is located at the front and rear sides of the right end of the internal seal body 25, and continues to extend from the bottom surface of the fixed block 31 under the action of the spring 35, and can limit the sample blocks on the lower and inner sides of the external seal body 1 on the front and rear sides, so that the device can be stably placed on the outside of the sample block, avoiding the sample block from shifting forward and backward on the lower and inner sides of the external seal body 1, resulting in line offset, affecting the accuracy of the fixed point.

[0029] Furthermore, the threaded sleeve 22 and the fixing ring 23 are both sleeved on the outside of the handle 21 , and the threaded sleeve 22 and the fixing ring 23 can move up and down on the outside of the handle 21 .

[0030] Furthermore, the guide rod 24 passes through the outer seal body 1 and the upper height-increasing gasket 26 , and the guide rod 24 provides guidance and connection for the movement of the inner seal body 25 driven by the rotation of the threaded sleeve 22 .

[0031] Furthermore, the inner seal body 25 is located inside the outer seal body 1 , and the outer wall of the inner seal body 25 abuts against the inner wall of the outer seal body 1 . The inner seal body 25 cooperates with the outer seal body 1 to mark and locate sample blocks of two sizes.

[0032] Furthermore, two groups of positioning structures 3 are installed, and the two groups of positioning structures 3 are respectively located on the front and rear sides of the right end of the internal seal body 25. The two groups of positioning structures 3 can limit the sample blocks on the lower and inner sides of the external seal body 1 on the front and rear sides, so that the device can be placed stably on the outside of the sample block, avoiding the sample blocks from moving forward and backward on the lower and inner sides of the external seal body 1, resulting in line deviation, affecting the accuracy of the fixed point.
