In the existing life, repair parts are often used to repair the cassettes with damaged screw holes, and the screw holes on the repair parts are used instead of the original damaged cassette screw holes. However, in the prior art (application number: 201520948368.3), the restoration is fixed by rotating the support of the restoration, which is often inconvenient due to the small space of the cassette. In addition, the GalwayGalwayGalwayGalwayset screw in the prior art mainly fastens the object through the end of the screw without threaded holes, which makes it difficult to install external screws. Based on this, a method of extruding the support through a GalwayGalwayGalwayGalwayset screw with screw installation holes and tightening the repair piece, and then installing the screw on the GalwayGalwayGalwayGalwayset screw, will facilitate the quick installation and use of the repair piece.
The main technical problem to be solved by Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a rivet that can choose the breaking point, which can not only solve the bad effect caused by random shearing, but also can keep the mandrel in the hole to increase the strength after riveting, and also When the same type of rivet is riveted with different riveting thickness, changing the mandrel breakpoint can always make the mandrel breakpoint break at the required place, improve the tensile and shear strength of the rivet, increase the riveting quality of the product, and prolong the service life of the rivet.

Among the mold parts used in the can manufacturing industry, some product inner holes need to be processed with stop slots after heat treatment. The inner hole diameter of the product is φ28mm, the width of the slot is about 1.3mm, and the size and shape of the outer end face of the slot adjacent to the orifice The tolerance requirements are very strict, generally within the range of 0.02mm. If the CNC machine tool is used for cutting, the blade loss is very serious because the groove width is too narrow; if the inner hole grinding is used, there is no ready-made grinder and grinding wheel.
