[0002] At present, the length of bolts on the market is strictly controlled according to the specifications and models. Bolt holes of the same diameter need to be equipped with bolts of various lengths because of their different lengths. This situation is especially common in automobile welding fixtures. The length of the bolts is also different, which makes the selection of bolts complicated, resulting in uneven bolt spare parts on site, and often there are many bolts and few bolts; bolt holes on the workpiece are often encountered during the on-site installation of automobile welding fixtures The axis is not perpendicular to the two ends of the workpiece, so it is very necessary to design a multi-functional bolt that can be pressed against double slopes on the fixture

The invention belongs to the technical field of bolts, and in particular, relates to a multifunctional bolt suitable for pressing double inclined surfaces. The multifunctional bolt comprises a first bolt head, first universal joints, a first stud, a first extension rod, a first spring, a first positioning block, a positioning bar, a bolt head round hole, a T-shaped connecting block, a C-shaped spring, a second stud, a bolt head square hole, a clamping groove, a guide rail guide groove and the like, wherein the two bolt heads and the studs are provided with the first universal sections and second universal sections; through the first universal sections and the second universal sections, the bolt can tightly press workpieces under the condition of the two ends of the workpieces being inclined surfaces; through cooperation of the clamping groove and the second positioning block, the length change of the bolt is realized; the length variable of the bolt is controlled to a certain extent, so that the bolt freely extends, the troubles caused by various length specifications of the bolt are reduced, and a vehicle welding fixture high in bolt demand is higher in practical effect; and in addition, the universal sections are added at the two ends of the bolt, so that higher use effect on clamping of two workpieces as the inclined surfaces is achieved.
