The elastic force of the extrusion spring 21 is greater than the elastic force of the push-back spring 19. When the L-shaped rod 20 is released, the elastic force of the extrusion spring 21 will push the push block 16 to move downward and squeeze the inclined surface of the fixed block 17.

Because the elastic force of the extrusion spring 21 is greater than the elastic force of the push-back spring 19, when the L-shaped rod 20 is released, the elastic force of the extrusion spring 21 will push the push block 16 to squeeze the inclined surface of the fixed block 17, so that the fixed block 17 can be inserted into the inside of the plug-in block 18, and the clamping piece 12 can be fixed, thereby realizing the function of replacing different clamping pieces 12 according to the shapes of different workpieces to be laser clad. It is very flexible and convenient to use, and its practicality is improved.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
