Description
Technical Field
The invention relates to the field of electric drills, in particular to an electric drill with diversified protection functions.
Background
An electric drill is a common tool for drilling, screwing and screwing in the mechanical industry, the building industry and the decoration industry. The working principle of the electric drill is that a motor rotor of an electromagnetic rotary type or electromagnetic reciprocating type small-capacity motor does magnetic field cutting work-doing operation, and the operation device is driven by a transmission mechanism to drive a gear to increase the power of a drill bit, so that the drill bit scrapes the surface of an object and better penetrates the object.
Electric drills can be classified into 3 categories: electric hand drills, impact drills, hammer drills.
1. Electric hand drills: the power is minimum, the application range is limited to wood drilling and the use of the electric screwdriver, and part of electric hand drills can be changed into special tools according to the application, and the application and the types are more.
2. Impact drilling: the impact mechanism of the impact electric drill is of a dog-tooth type and a ball type. The ball type electric impact drill is composed of moving disk, fixed disk and steel balls, the moving disk is connected with main shaft by means of screw thread and is equipped with 12 steel balls, the fixed disk is fixed on the machine shell by means of pin and is equipped with 4 steel balls, under the action of thrust the 12 steel balls can be rolled along the 4 steel balls, so that the hard alloy drill bit can produce rotary impact motion, and can drill hole on the brittle materials of brick, building block and concrete, and can be separated from pin, and the fixed disk can be rotated together with fixed disk, and can not produce impact, so that it can be used as general electric drill.
3. Hammer drill (electric hammer): the hole can be drilled on any material, and the application range is widest.
When the drill bit is installed, the end part of the drill bit is usually inserted into the installation seat to be clamped, and in the process of starting the electric drill to enable the drill bit to rotate at a high speed, once the drill bit is disengaged from the mounting seat, the high speed rotation of the drill bit may injure the worker, thereby having a significant factor of unsafe, when drilling on a plane, once the drill bit and the mounting seat are loosened, the drill bit can be blocked in the object to be drilled and is difficult to pull out, secondly, dust particles are easy to splash in the drilling process, when the dust particles are large, particularly when the wood board is drilled, the splashed wood chips can enter eyes of workers, at the moment, the drill bit is in a high-speed rotation state, great damage can be brought to workers due to the fact that the drill bit is touched by mistake, in addition, the maximum depth of the hole is not convenient to determine in advance by the existing electric drill, in some cases where uniform drilling depths are required, there may be a problem of uneven hole depths.
