Description

Technical Field

[0001] The present invention relates to the field of automobile sheet metal repair, and in particular to a repair bracket for automobile sheet metal, and a drawing piece and a supporting seat on the sheet metal repair bracket. Background Art

[0002] Sheet metal repair brackets are used for automotive sheet metal repairs and generally consist of three main components: a crossbeam, a puller, and a support base. The puller and support base are mounted on the crossbeam. The sheet metal repair bracket works by using the support base to support the bracket on the automotive sheet metal. The puller hooks the puller pins spot-welded in the sheet metal depressions, and then applies force to lift the pins nailed in the sheet metal depressions, thereby driving the sheet metal to recover. The puller and support base on traditional sheet metal repair brackets are fixed to the crossbeam and cannot be moved left or right to adjust their position, which can cause a lot of inconvenience during actual use. In order to improve this situation, some existing sheet metal repair brackets have improved the structure of the crossbeam, pulling piece and support seat, so that the pulling piece and the support seat can move left and right on the crossbeam. For example, the Chinese invention patent "Pulling assembly and sheet metal repair puller" with patent number 201910192247.0 discloses a structure in which a transverse through hole is provided on the pulling piece and the support seat, and the crossbeam is installed through the transverse through hole.
