Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, the present embodiment provides a welding tool, which includes a workbench 1, a bottom block 2 is installed on the workbench 1, two clamping blocks 3 are rotatably installed on the bottom block 2, a groove is formed on one side, close to each other, of the two clamping blocks 3, a top rotating structure is installed on the workbench 1, and the top rotating structure is used for driving the two clamping blocks 3 to rotate in a direction deviating from each other.

The top rotating structure comprises a top plate 4 and an elastic piece; the clamp splice 3 is installed on the bottom block 2 through the pivot rotation, all is connected with in the pivot of two clamp splice 3 and does not show in the gear diagram, and two gears intermeshing can ensure that two clamp splice 3 can realize rotating in step. The roof 4 is located the lower extreme of two clamp splice 3, and roof 4 is located between the pivot on two clamp splice 3, and the length of roof 4 is less than the interval between the pivot on two clamp splice 3, and the elastic component is connected between roof 4 and workstation 1, and the elastic component is used for driving roof 4 upward movement.
