Through the above structure, the positioning of the plastic shell 10 can be achieved, ensuring that the installation positions of the plastic shell 10 and the screw bearing 9 correspond to each other; four convex rods 1601 are fixed at equal angles on the upper end of the pressing sleeve 16, and the convex rods 1601 are nested with the installation sleeve 15, and the pressing sleeve 16 is fixed to the installation sleeve 15 by a latch 1602. Through the above structure, it is convenient to position, install and disassemble the pressing sleeve 16, so as to replace different pressing sleeves 16 later;

[0021] When using the laser welding coupling clamping fixture, Figure 1-Figure 4 As shown, the device can be moved to a suitable position by the caster 101, and the device can be positioned and leveled with the threaded foot pad 102. Then, according to the size of the plastic shell 10, a suitable positioning sleeve 8 and a pressing sleeve 16 are selected for installation.
