Drill bit sleeve

Abstract

The invention discloses a drill bit sleeve applied to the field of building construction equipment. The drill bit sleeve comprises a cylinder, a base and a guide piece sleeved with an elastic piece. Aconnecting hole allowing a drill bit to be inserted therein and matched with a drill bit tool profile at the tail end of the drill bit is formed in the center of the base. A fastening structure is arranged at the position where the base and the connecting hole are attached to the drill bit tool profile at the tail end of the drill bit. A dust collection connector connected with an external dust collector is arranged on the wall of the cylinder. A stroke control mechanism is further arranged between the cylinder and the base. Due to the fact that no sleeve is arranged outside a traditional drill bit, the drill bit can be severely polluted by dust, and evenly splashing injuries can be caused. The drilling depth of the traditional drill bit cannot be limited, and consequentially, the situation that the drilling depth is insufficient or a board is excessively drilled occurs frequently. The drill bit sleeve can be arranged outside a drill bit in a sleeving mode when a tool such as an electric hand drill / impact drill is in use, so that dust and splashing are prevented, an operator is protected, and the drilling depth can be limited.

Description

technical field [0001] The invention belongs to the field of building construction equipment, and in particular relates to a drill bit sleeve, which is suitable for being set on the outside of drill bits such as electric hand drills, impact drills, and bench drills. Background technique [0002] During construction, especially when home furnishing, such as wall lamps, wall cabinets, water heaters, televisions and other electrical appliances that need to be hung on the wall, it is necessary to use a hand drill / impact drill to clean walls, stones and wood. Make holes. Problems in the drilling process: 1. There is no sleeve on the outside of the traditional drill bit, and the high-speed flying drill bit will raise the dust, and the dust pollution is quite serious, especially when the wall and furniture are drilled during the post-decoration construction of the house that has been occupied. The operating dust is very large and difficult to clean; operators who inhale dust for a...

Problems solved by technology

Problems in the drilling process: 1. There is no sleeve on the outside of the traditional drill bit, and the high-speed flying drill bit will raise the dust, and the dust pollution is quite serious, especially when the wall and furniture are drilled during the post-construction of the interior that has been occupied. The operating dust is very large and difficult to clean; operators who inhale dust for a long time are also prone to pneumoconiosis, and various small particles are splashed around, which can easily hurt the operator's face and even eyes, and there are even emergencies, such as when the drill bit is rotating at a high speed Sudden breakage and flying out will cause unimaginable serious consequences; 2. Traditional drills cannot limit the drilling depth, so there are often situations where the drilling depth is not enough or the plate is drilled through
