The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The first embodiment is as follows:

a base plate 1;

the fixing mechanism 2 comprises a fixing support 21 and a rotating support 22, the rotating support 22 is arranged on the bottom 1, and the fixing support 21 is detachably and rotatably connected to the rotating support 22;

limiting mechanism 3, including fixture block 31, fixture block 32, fixture block 31 includes clamping piece 311 and holder 312, clamping piece 311 rotates to be connected on holder 312, be equipped with draw-in groove 321 on fixture block 32, fixture block 31 corresponds and sets up on the bottom plate 1 of fixed bolster 21 front end direction, fixture block 32 corresponds and sets up on the bottom plate 1 of fixed bolster 21 rear end direction.

Specifically, the clamp is arranged on a workbench of a welding machine table through a bottom plate 1; when welding, firstly, the fixed support 21 is detached from the rotating support 22, the upper surface of the fixed support 21 is placed downwards in the clamping groove 321 of the clamping block 32, the lifting arm main plate element is placed on the upward lower surface of the fixed support 21, then the fixed support 21 and the lifting arm main plate element are connected with the rotating support 22 together, then the fixed support 21 and the lifting arm main plate element are overturned from the clamping groove 321 around the rotating support 22 to one side of the clamping block 31, the lifting arm main plate element is positioned below the fixed support 21 after overturning, the edge of the lifting arm main plate element needing to be welded is upward, at the moment, the lifting arm main plate element is connected with the clamping seat 312, the lifting arm auxiliary plate element is placed at the welding position of the lifting arm main plate element, and then the clamping piece 311 is used for fixing the lifting arm auxiliary plate element, so that the lifting arm auxiliary plate element cannot be displaced during welding, and the workpieces can be welded after being fixed; after the welding is completed, the clamping pieces 311 are opened, the fixed support 21 and the lifting arm workpiece are detached from the rotating support 22, and the fixed support 21 is taken out from the lifting arm workpiece welded into a cylindrical shape, so that the whole operation step is completed. The utility model has the advantages that: 1. the jack part can be quickly positioned and installed, and the working efficiency is improved; 2. The positioning is accurate, the welding precision is ensured, and the quality of finished products is improved; 3. the parts of the lifting arms of the two groups of jacks can be fixed at the same time.

Example two:
