The laser marking machine includes control buttons, regulators, guide rods, adjusting devices, protective sleeves, positioning cylinders, limiting sleeves, auxiliary gears, drive gears, adjusting rods, portable straps, rotating blocks, rotating rings, storage springs, rotating plates, limiting rods, and rotating springs. When the laser marking machine is in use, the adjusting device 7 is used to adjust the laser marking machine. The laser marking machine can mark objects with laser. The drive motor 77 is started, which drives the drive gear 76 to rotate. The drive gear 76 rotates and drives the auxiliary gear 75, which in turn rotates and drives the adjusting rod 78. The adjusting rod 78 rotates and adjusts the height of the regulator 5. When the regulator 5 is slid to the specified position, the positioning cylinder 72 is started. The drive end of the positioning cylinder 72 is inserted into the limiting sleeve 73. The drive end of the positioning cylinder 72 is inserted into the positioning port 74. The drive gear 76 stops rotating, and the adjustment is completed. The adjusting device 7 effectively adjusts the laser marking machine, improving the adjustability, practicality, and convenience of the laser marking machine. It reduces the labor of workers and saves the adjustment time of the laser marking machine. When the laser marking machine is in use, the portable device 8 is used to make the laser marking machine portable. The laser marking machine can mark objects with laser. Pulling the rotating ring 84 drives the portable strap 81 to extend. The rotating ring 84 is sleeved on the rotating block 83. The rotating ring 84 is sleeved in the clamping groove 82. The storage spring 85 drives the storage rod 87 to rotate, which in turn pulls the portable strap 81. The rotating ring 84 is clamped in the clamping groove 82, and the portable device 8 effectively makes the laser marking machine portable, improving the portability, practicality, and convenience of the laser marking machine. It reduces the inconvenience of carrying the laser marking machine and the difficulty of carrying the laser marking machine. When the laser marking machine is in use, the anti-slip device 9 is used to make the laser marking machine anti-slip. The laser marking machine can mark objects with laser. The device is placed on the base 2. The control rod 97 is inserted into the storage sleeve 96. The rotating plate 92 is loosened and rotated by the rotating spring 95. The rotating plate 92 is inserted into the anti-slip sleeve 91. The limiting rod 93 is rotated and inserted into the storage sleeve 96, limiting the rotation of the rotating plate 92. The anti-slip device 9 effectively makes the laser marking machine anti-slip, improving the anti-slip property, practicality, and safety of the laser marking machine.
