[0046] Working principle: When welding the aluminum profile, first start the motor 57 so that the second conical tooth 58 drives the first conical tooth 54 to rotate. At this time, the stud 53 rotates in the movable groove 5, and the threaded connection between the stud 53 and the clamping plate 51 changes the distance between the clamping plates 51 to achieve the clamping effect of the aluminum profile placed on the placement table 2.
