the transmission structure of the track 8011 may be specifically as shown in fig. 8, a driving wheel 8042 is fixedly connected to the other end of a connecting rod 8041 on a rotating handle 804, a driven wheel 8021 is sleeved on an outer surface of a pushing screw 802, an internal thread 80211 matched with the pushing screw 802 is arranged on an inner surface of the driven wheel 8021, and the outer surfaces of the driving wheel 8042 and the driven wheel 8021 are attached to the track 8011 to realize transmission connection of the track 8011, meanwhile, as shown in fig. 9, the driven wheel 8021 is arranged to be matched with the driven wheel 8021, and secondary fixing members 8022 fixed relative to the base 100 are further arranged at two ends of the driven wheel 8021 along an axial direction of the pushing screw 802, for example, when the transmission case 801 is arranged and the transmission case 801 is fixedly arranged on the base 100 in this embodiment, the secondary fixing members 8022 are fixedly connected to an inner wall of the transmission case 801, as shown in fig. 10, the secondary fixing members 8022 and the driven wheel 80, The first annular groove 80212 is disposed on the driven wheel 8021, the centers of the first annular protrusion 80221 and the first annular groove 80212 are on the axial line of the pushing screw 802, the auxiliary fixing member 8022 is further provided with a through hole 80222 for the pushing screw 802 to pass through, and the hole wall of the through hole 80222 is not in contact with the pushing screw 802, after the above structure is disposed, the driven wheel 8021 has extremely high disposition stability, in addition, as shown in fig. 11, the auxiliary fixing member 8022 is disposed in cooperation with the driving wheel 8042, and in the axial direction of the rotation central axis of the rotating handle 804, the driving wheel 8042 is further provided with at least one main fixing member 8043, and the main fixing member 8043 is fixed relative to the base 100, for example, the main fixing member 8043 is fixedly connected to the inner wall of the transmission case 801, as shown in fig. 12, the main fixing member 8043 and the driving wheel 8042 are rotatably connected by the second annular protrusion 80431 and the second annular, The second annular groove 80421 is disposed on the driver 8042, and the centers of the second annular protrusion 80431 and the second annular groove 80421 are both on the central axis of rotation of the rotating handle 804.

The driving structure of the crawler 8011 is only one arrangement, and the driving structure of the crawler 8011 with the other arrangement can achieve the same or equivalent technical effects as the embodiment, and should be included in the protection scope of the present invention;

after the structure is arranged, the two vertical shafts 500 can drive the bearing 501 to move towards the seat plate 200 or move away from the seat plate 200, so that the workpieces 700 with different sizes can be adapted, and on the other hand, the arrangement mode of the soft crawler 8011 can avoid damage to the workpiece 700 or damage to the matrix assembly 400 caused by excessive clamping.

The carving tool with the structure can be suitable for carving characters on workpieces 700 of different shapes and sizes, the height and the angle of the carving character processing can be adjusted conveniently, the carving character changing operation is simple and convenient, the stability of the whole structure is high, and the carving tool has high practicability.
