Under the action of spring 1, the semicircular card plate will be embedded in the arc-shaped positioning groove, thereby limiting the position of the rotating block and the sliding card plate, ensuring the stability of the handheld marking gun. In this way, when carrying, the power control box and the handheld marking gun can be easily carried together by simply lifting the handle, which greatly improves the portability of the laser marking machine.

[0018] 2. The utility model provides a convenient laser marking machine. Through the mutual cooperation among the annular connecting frame, motor, driving wheel, driven gear ring, connecting plate, sliding top plate, spring 2, pushing rod, rotating plate, connecting column and arc-shaped cleaning brush, when cleaning the mirror surface of the laser marking machine, starting the motor can drive the driving wheel, which in turn drives the driven gear ring to rotate, prompting the connecting plate to rotate, so that the sliding top plate is disengaged from the arc-shaped slot. Subsequently, under the action of the pushing rod, the rotating plate starts to rotate, and the connecting column drives the arc-shaped cleaning brush to reach the bottom of the laser marking machine mirror surface. Through the rotation of the arc-shaped cleaning brush, the mirror surface is effectively cleaned, ensuring the cleanliness of its surface, thereby avoiding the potential influence of dust on the performance of the laser marking machine.
