The movable base 1 is mounted on the guide rail 2, and a laser head 4 is movably mounted on the movable base 1. The assembly also includes:

[0026] Adjustment mechanism 6 is mounted on laser head 4;

[0027] Protective cover 5 is slidably mounted on laser head 4;

[0028] The limiting mechanism 7 is installed on the laser head 4. The limiting mechanism 7 opens and closes while the protective cover 5 is raised and lowered by the adjusting mechanism 6.

[0029] The laser head 4 is equipped with a mounting box 43 and a locator 42, which can accurately locate the engraving position and greatly improve the engraving accuracy. The mounting box 43 is equipped with a plug 41.

[0030] The adjustment mechanism 6 includes a crossbar 61, which is mounted on the mounting box 43. A gear 64 is mounted on the crossbar 61. An upright rod 63 is mounted inside the mounting box 43 and is located on both sides of the crossbar 61. Both the upright rod 63 and the crossbar 61 are equipped with bevel gears 62, which are used to adjust the upright rod 63 synchronously. The bevel gears 62 mesh with each other.

[0031] The limiting mechanism 7 is located at the upper and lower ends of the mounting box 43. The limiting mechanism 7 includes a sliding plate 71, which is threaded onto the upright 63. A column 73 is provided on the sliding plate 71. The limiting mechanism 7 is slidably mounted on the mounting box 43 via the column 73. A limiting claw 72 is provided on the sliding plate 71 via the column 73.

[0032] The protective cover 5 is provided with a sliding block 51, the protective cover 5 is slidably arranged on the mounting box 43 through the sliding block 51, the protective cover 5 is provided with a rack 52, the rack 52 is slidably arranged on the mounting box 43, the rack 52 is engaged with the gear 64, and the protective cover 5 can effectively protect the carving head and prevent the carving head from being accidentally damaged, such as being collided or scratched, thereby prolonging the service life of the laser head 4.
