However, the strong magnetic force of this structure always exists. After welding is completed, it is difficult to remove the welding trolley from the workpiece. In response to the above shortcomings, the applicant applied for a detachable small vertical and horizontal welding trolley with patent number CN202022811243.7. The adsorption and separation of the movable trolley and the workpiece are achieved by setting a magnetic switch. It is easy to install and has a lighter weight. When the magnetic switch is turned on, the strong magnetic attraction generated by the magnetic switch adsorbs the workpiece, and the pressing plate ensures that the magnetic switch is in the open state, and the welding trolley will not fall off the workpiece. However, the magnetic switch of this structure uses two strong RuFeB magnets, which are expensive and use large-volume strong magnets, which is not conducive to improving product competitiveness. In addition, the magnetic switch needs to be pressed to limit the opening state, which is cumbersome to operate. Utility Model Content
