Electric tools classified according to the movement in a variety of forms, but the more common are two, one is for rotation, the other is for reciprocating motion. Electric tools for reciprocating movement generally hold the cutting tool, and the current electric tool to hold the cutting tool device is such that: it is in the output shaft axis split a plane, the plane has a fixed hole, and then use the platen And bolts will be pressed and fixed cutting tool, the structure of the assembly and disassembly are more complicated, but also relatively easy to loose, so less than ideal. The purpose of the utility model is to provide a cutting tool clamping device for an electric tool, which is convenient when the cutting tool is assembled and disassembled, and the cutting tool will not be loosened when used, and the structure is reliable and reasonable. The cutting tool clamping device for an electric tool comprises an output shaft, a slot for inserting a cutting tool is arranged at the end of the output shaft, a fixing sleeve is arranged outside the output shaft, a positioning hole is arranged on the output shaft on one side of the slot, , A positioning pin is arranged in the positioning hole, a rotating sleeve oil-free screw vacuum pump is arranged outside the fixing sleeve, a torsion spring is arranged between the output shaft and the rotating sleeve, the eccentric arc is always pressed against the positioning pin, one end of the torsion spring is inserted Groove, the other end inserted into the rotating sleeve end face set the hole, Boshan submersible pump eccentric arc has the most distal bulge to prevent the positioning pin slides out; rotating sleeve with a hole for assembly Positioning pin when used; craft hole with a process plug; rotary sleeve fixed with a plastic sleeve; plastic sleeve by the larger front sleeve and a smaller rear sleeve halves of the buckle, the former sleeve envelope enveloping , After the sleeve will be enveloping the torsion spring; process plug connected to the back cover. The utility model is convenient to assemble and disassemble the cutting tool, when the assembly is released, the rotating sleeve is loosened, the cutting tool is inserted into the slot of the output shaft, the positioning pin is automatically locked in the fixing hole on the top cutting tool, the rotating sleeve is under the action of the torsion spring, Eccentric arc will be fixed pin positioning pin, remove the cutting tool as long as the release of the rotating sleeve, so that the pin from the fixture pin clever exit, you can dial out the blade. The utility model has the advantages of simple and reasonable structure, easy and convenient use, fixed and reliable cutting tool, and the cutting tool will not be loosened freely during use.
