Detailed Description
Referring to fig. 1, 2 and 3, the multi-functional impact hammer of the present invention is shown.
As shown in FIG. 1, the multifunctional impact hammer comprises a hammer body and an impact block 14, wherein the front end of the hammer body is provided with a threaded connection part 13 (such as a bypass and generator cover plate of 331-350C type APU, a generator cover plate of 131-9A type APU and the like) connected to a loose part to be disassembled, and the impact block 14 is slidably arranged on the hammer body to form impact force.
Referring to fig. 2, the hammer body includes a long rod-shaped rod body 10, a disk-shaped rear stop block 11 is disposed at a rear end of the rod body 10, a disk-shaped front stop block 12 is disposed at a front end of the rod body 10, diameters of the rear stop block 11 and the front stop block 12 are larger than a diameter of the rod body 10, and the impact block 14 is a cylindrical member sleeved on the rod body 10, and has an inner diameter smaller than diameters of the rear stop block 11 and the front stop block 12, so that when an operator operates the hammer body, a component screwed to a threaded connection portion forms an impact force through impact of the impact block 14 on the rear stop block 11 and the front stop block 12.
Wherein, referring to fig. 3, the impact block 14 may be composed of two pieces fixed by welding, and diamond knurls 141 are formed at the outer edge of the impact block 14 for easy operation.
