The connecting plate three 36 arranged on the connecting plate two 35 can realize that during the movement of the connecting plate three 36, the guide plate 361 fixedly connected thereto is driven to move, the moving guide plate 361 drives the tooth plate 511 to move, and during the movement of the tooth plate 511, the gear 531 connected thereto is adjusted to rotate, so as to adjust the clamping angle of the clamping plate 532.

[0039] Reference Figure 6-Figure 8 The threaded rod 42 is provided with two sections of threads, and the rotation directions of the two sections of threads are opposite. A guide rod 43 is fixedly arranged between the two brackets 41, and the guide rod 43 and the threaded rod 42 are arranged parallel to each other. Through the two sections of threads arranged on the threaded rod 42, it is achieved that during the rotation of the threaded rod 42, the moving plate 51 threadably connected thereto can move toward each other at the same time, and the guide rod 43 is arranged to prevent the moving plate 51 from being displaced during the movement.

[0040] Reference Figure 7-Figure 8 The extrusion plate 55 is arranged in an arc shape as a whole, and a plurality of evenly distributed anti-skid edges 56 are fixedly arranged on the clamping surface of the extrusion plate 55. By arranging the extrusion plate 55 in an arc shape, the contact surface between the extrusion plate 55 and the material is improved, and the stability of the device is improved. The anti-skid edges 56 are arranged on the extrusion plate 55 to further increase the friction between the extrusion plate 55 and the material.

[0041] Reference Figure 5-Figure 7The guide groove 362 is arranged in a T-shape, and the tooth plate 511 is fitted with the inner wall of the guide groove 362. By arranging the guide groove 362 in a T-shape, the tooth plate 511 is prevented from axial displacement during the movement.

[0042] Reference Figure 3-Figure 5 The support plate 31 is telescopic, and the top of the support plate 31 abuts against the inner wall of the protective shell 2. By setting the support plate 31 to abut against the protective shell 2, the overall stability of the device is improved, and the telescopic support plate 31 is more convenient.

[0043] The specific solution is as follows: when using the device, the staff first fixes the device in a suitable position, and through the vertical plate 14 set on the shell 1 and the sleeve 141 set on the vertical plate 14, the staff can place the electronic tag on the placement plate 15 of the device, and then rotate the connecting rod 142 to hook on the scraper 13 to achieve positioning and fixing of the electronic tag placed on the placement plate 15. The cavity set in the sleeve 141 can achieve that during the installation process, the elastic force generated by the spring 144 can pull the connecting rod 142 back and buckle on the scraper 13, thereby improving the stability of the device. Qualitatively, when positioning the square box 3, the staff first starts the motor 411 to rotate the threaded rod 42 fixed on the output end of the motor 411. The rotating threaded rod 42 can adjust the clamp 5 set on its outer circumference to reinforce the support rod 22 and prevent damage to the material inside the device. During the rotation of the threaded rod 42, the movable plate 51 threadedly connected to the threaded rod 42 moves to reinforce the transverse support rod 22. When the support plate 31 moves, the longitudinal support rod 22 is clamped by driving the clamping plate 532 to rotate.
