[0003] The existing hole opener is mainly composed of a rotating handle and a hole saw body. The rotating handle and the hole saw body are generally connected together by threads. If the hole saw body needs to be replaced, the originally installed hole saw Unscrew the screw, and then install the new hole saw body, but because the hole saw body has been drilled, there may be slippage or seizure between the threads, and it is often difficult to disassemble. It is also difficult to quickly clean up the waste in the

The invention belongs to the technical field of electric tools, in particular to a quick replacement system for a perforator saw blade, a perforator assembly with the quick replacement system, and a quick saw blade replacement method based on the quick replacement system. The quick replacement system comprises a first connecting mechanism and a connecting releasing mechanism which are detachably matched; the connecting releasing mechanism comprises a second connecting mechanism; a first stress end and a second stress end are respectively arranged on a first connecting piece and a second connecting piece; and the arrangement directions of the first stress end and the second stress end corresponding to the driving and rotating directions, so that torque is transferred to drive a saw blade after the first stress end is matched with the second stress end. Therefore, quick mounting and releasing of the saw blade can be realized; and quick locking and stepless replacement of the saw blade can be realized by matching a further arranged separable panel.
Description
Technical field [0001] The invention belongs to the technical field of electric tools, and in particular relates to a quick change system for a hole opener saw blade, a hole opener assembly with the quick change system, and a quick change method for saw blades based thereon. Background technique [0002] The hole opener is a circular saw for processing circular holes. It can open holes on metal, wood, plastic, glass, stone and other materials. Because of its simple and flexible operation, convenient portability, it is extremely versatile. [0003] The existing hole opener is mainly composed of a rotary handle and a hole opener body. The rotary handle and the hole opener body are generally connected by threads. If the hole opener body needs to be replaced, the original installed hole opener must be replaced. Unscrew the screw, and then install the new hole opener body, but because the hole opener body has been drilled, there may be slippage or seizure between the threads, which is o...
