A plurality of movable blocks 7 are provided in each of the plurality of movable blocks 7 for fixing objects. The fixing mechanism includes a chamber 11 opened in the movable block 7, an electromagnetic armature 12 is provided in the chamber 11, and a coil 13 is wound around the outer wall of the electromagnetic armature 12. The magnetic force generated by the plurality of electromagnetic armatures 12 is used to adsorb the marking part, thereby realizing rapid fixation of the marking part, thereby ensuring the stability of the marking part during the marking operation.

[0022] A moving mechanism for moving the moving block 7 is provided in each of the through slots 5. The moving mechanism includes a transmission cavity 14 opened in the base 1. Threaded rods 6 are rotatably connected between the through slots 5 and the transmission cavity 14. The threaded rods 6 respectively penetrate the multiple moving blocks 7 and are threadedly connected thereto. Through the threaded connection between the moving blocks 7 and the threaded rods 6, the multiple moving blocks 7 are moved, thereby changing the distance between the multiple moving blocks 7, so that the device can fix markers 4 of different sizes, thereby improving the adaptability of the device.

[0023] A wire clamp 9 is provided at the lower end of the base 1 . A plurality of connecting wires 10 are passed through the wire clamp 9 . The plurality of connecting wires 10 respectively pass through the plurality of moving blocks 7 and are electrically connected to the plurality of coils 13 .

[0024] A power motor 15 is provided in the transmission cavity 14 . A rotating shaft is provided at the end of the output shaft of the power motor 15 , and a rotating plate 16 is provided on the outer wall of the rotating shaft.

[0026] When the present invention is used, when fixing the object to be marked, the connecting wire 10 is energized to the coil 13 by using the existing technology (the electrical connection between the two is the existing technology, so the relevant structure is not described in detail in this figure), and the energized coil 13 is combined with the electromagnetic armature 12 to make the electromagnetic armature 12 generate magnetism, and then the object to be marked is placed on the upper end of the multiple moving blocks 7, so that the magnetic force generated by the multiple electromagnetic armatures 12 adsorbs the object to be marked, thereby achieving rapid fixation of the object to be marked (the object to be marked is a metal material that is easily absorbed), thereby ensuring the stability of the object to be marked during the marking operation;

[0027] When the distance between the multiple moving blocks 7 needs to be changed, the power motor 15 is started, so that the power motor 15 drives the rotating shaft to rotate, and the rotating plate 16 on the outer wall of the rotating shaft rotates, thereby rotating the bevel gear ring 17 at the lower end of the rotating plate 16. The bevel gear ring 17 is meshed with the multiple bevel gears 18, so that the multiple bevel gears 18 rotate and drive the multiple threaded rods 6 to rotate. The threaded connection between the moving block 7 and the threaded rod 6 is utilized to move the multiple moving blocks 7, thereby changing the distance between the multiple moving blocks 7, so that the device can fix markers 4 of different sizes, thereby improving the adaptability of the device.
