[0015] Beneficial Effects

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The laser spot welding machine of the utility model is provided with a support component which can slide freely horizontally in the inner cavity of the machine body. When laser spot welding is performed on jewelry, the worker holds the jewelry with both hands, then extends the jewelry into the machine body through the operation channel, places the wrist in the U-shaped groove of the support seat, and then moves both hands to perform the spot welding work. Since the wrist has a support point, the palm of the worker can be supported during the spot welding process, which is equivalent to the jewelry having a support and positioning, and no shaking will occur during the spot welding process, thereby improving the welding accuracy. After the spot welding work is completed, the wrist is moved until the support seat is adsorbed and fixed on the limit strip, which is convenient for secondary operation and very convenient to use.
