Description
Technical Field
The utility model belongs to the technical field of electric tool part and specifically relates to a can dismantle guard shield of angle mill is related to.
Background
Angle grinders (grinders), also known as grinders or disc grinders, are abrasive tools used for cutting and grinding glass fiber reinforced plastics. An angle grinder is a portable electric tool for cutting and polishing glass fiber reinforced plastics, and is mainly used for cutting, grinding and brushing metal and stone materials. According to different use functions, the angle grinder can be respectively provided with a cutting piece or a polishing piece. The angle grinder has high rotating speed, and certain risks exist when the cutting piece and the grinding piece work, so the angle grinder is generally provided with a protective cover for protection. The cutting blade and the polishing blade have different corresponding protective cover structures due to different operation modes, and the cutting blade needs to be matched with a protective cover with a full-protection structure due to the fact that the outer ring is in contact with a cutting object; when the polishing disc works, the polishing disc is contacted with an object through a polishing surface, and a shield of a semi-protection structure is needed to be matched; when the working state of the polishing plate with a small polishing angle is achieved, in order to achieve a better protection and dust prevention effect, the semi-protection protective cover needs to be expanded, and the top surface of the polishing plate is enabled to be fully covered.
At present, generally all be the guard shield of two kinds of structures of collocation when most angle grinder goes out goods on the market, the usage is different, need dismantle the change, and the operation is carried and is all very inconvenient, if can carry out the dismantlement formula combination with the guard shield of two kinds of structures, then will improve the convenience of operation. In order to solve the problem, a patent with a publication number of CN208261956U in the prior art discloses an angle grinder capable of combining a slicing shield and a grinding disc shield, and the patent document discloses that the slicing shield can be detachably sleeved on the outer side of the grinding disc shield and is limited by clamping pieces at two ends of the slicing shield, in the mode, the clamping pieces are preferably metal pieces and are firmly fixed, but the elasticity is insufficient, the disassembly is troublesome in the actual use process, the manual disassembly is difficult, other tools are often needed, and the fixing plates are arranged at the upper part and the lower part of the slicing shield, so that more materials are used, and the production cost is increased; and its guard shield only has two kinds of states, when working condition to polishing the angle is little, in order to play better protection dustproof effect, can't expand the guard shield of half protection.
In this regard, there is a need for improvement.
