[0002] Laser marking machines use laser beams to mark permanent marks on the surfaces of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and texts. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines and YAG laser marking machines. Laser marking machines are mainly used in some occasions that require more sophisticated and higher precision.

[0020] The present invention has the following beneficial effects:

[0021] The operator of the present invention can place the arc plate on the surface of the sports equipment through the holding frame, and then start the electric push rod to shrink. When the electric push rod shrinks, the arc plate is pushed to shrink through the connection between the extrusion plate and the slider. When the arc plate shrinks, the arc rubber plate inside will contact the surface of the sports equipment. The arc plate is fixed to the surface of the sports equipment by using the pressure of the electric push rod, so that the laser marking machine can be fixed to the surface of the sports equipment through the arc plate, thereby improving the convenience of the laser marking machine during installation. When the arc plate shrinks, the slider will slide inside the arc groove, thereby improving the stability of the arc plate during shrinkage and clamping.

At this time, the arc plate can be twisted and rotated by the holding frame to adjust the position of the laser marking machine. The laser marking machine can be fixed on the surfaces of different sports equipment by clamping and fixing the arc plate by shrinking.

[0022] When the arc plate of the present invention contracts, the rubber rod at the end of the extrusion push plate will contact the surface of the sports equipment. At the same time, the circular plate will also contact the surface of the sports equipment, and the circular plate will push the elastic rod to move toward the outer end of the arc plate as the arc plate contracts. When the elastic rod moves, it pushes the semicircular frame to deform through the connection between the forked frame and the round hole rod. After the center of the semicircular frame is subjected to pressure, the rear ends will approach each other and push the extrusion push plate to squeeze the surface of the sports equipment, thereby improving the stability of the arc plate when clamping the sports equipment, and further improving the stability of the arc plate when fixing the laser marking machine.

[0023] After the motor of the present invention is energized, the motor will drive the driving wheel to rotate, and the engagement between the driving wheel and the engagement groove will push the sliding frame to slide on the surface of the slide rail. When the sliding frame moves, it will synchronously drive the laser marking machine to move, so as to adjust the marking position of the laser marking machine, thereby improving the convenience of printing marks on the sports equipment. When the electric telescopic rod is started to move downward, the electric telescopic rod will push the lifting frame to move downward through the positioning plate, and the lifting frame will push the end of the triangular plate to unfold when it moves downward. When the triangular plate unfolds, it will push the telescopic rod to extend through the positioning frame, and the position of the laser marking machine will be adjusted by the extension of the telescopic rod, so as to adjust the distance between the laser marking machine and the sports equipment. At the same time, when the triangular plate moves downward, it will push the contact plate to contact the surface of the sports equipment and squeeze the sports equipment through the elastic rod, thereby improving the stability of the laser marking machine during marking.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
