A plurality of limiting blocks four 4 are connected to the bracket 1, and a positioning assembly is connected to the bracket 1, and the positioning assembly is connected to the limiting block three 8.
[0032] The positioning assembly includes a limiting shaft 9, an extension plate 10, a positioning plate 11, a limiting sleeve 14, a pull rod 15, a spring 16 and a stopper 17. A limiting shaft 9 is arranged on the bracket 1, and the limiting shaft 9 can slide on the bracket 1. The extension plate 10 is connected to the bracket 1, and the limiting sleeve 14 is connected to the extension plate 10. The pull rod 15 is inserted into the limiting sleeve 14. A positioning plate 11 is arranged at one end of the pull rod 15, and the positioning plate 11 passes through the end of the limiting sleeve 14. A plurality of limiting grooves corresponding to the positioning plate 11 are arranged on the limiting shaft 9. The limiting shaft 9 is connected to the limiting block 38. A spring 16 is sleeved on the pull rod 15. The pull rod 15 is provided with a boss for limiting one end of the spring 16. The limiting sleeve 14 is connected to the stopper 17. The stopper 17 is used to limit the position of the spring 16. The clamp 5 is preferably a good hand brand quick clamp 5, such as a clamp 5 with model HS-1 bracket 1j. The upper limit block 2 of the bracket 1 limits the edges of some parts to be welded, and then some parts are positioned, and multiple parts to be welded are stacked, such as stacked in a cross shape, and the parts to be welded are pressed by the clamp 5, which is convenient for positioning and pressing the parts to be welded, and by pulling the pull rod 15, the pull rod 15 drives the positioning plate 11 and the upper limit groove of the limit shaft 9 to separate, and then the limit shaft 9 and the limit block three 8 are moved, so that the limit block three 8 limits the end of the part at a suitable position. After loosening the pull rod 15, the elastic force of the spring 16 makes the positioning plate 11 and the corresponding limit groove on the limit shaft 9 cooperate to limit the position of the limit shaft 9, thereby achieving the effect of positioning the limit block five 18, which is convenient for limiting parts to be welded of different lengths. Through the cooperation between the spring 16, the positioning plate 11 and the limit shaft 9, it is convenient for the user to adjust the position of the limit shaft 9.
