Description

Technical Field

[0001] The utility model relates to the technical field of drill guns, in particular to a handheld high-speed drill gun. Background Art

[0002] The drill gun is convenient for drilling holes in workpieces. The drill gun is a type of electric drill. An electric drill is a drilling tool that uses electricity as power. It is a conventional product among power tools and also the most in-demand power tool product. The annual production and sales volume accounts for 35% of China's power tools. The main specifications of electric drills are 4, 6, 8, 10, 13, 16, 19, 23, 32, 38, 49 mm, etc. The number refers to the maximum diameter of the drill bit for drilling holes on steel with a tensile strength of 390N / mm2. The maximum drilling diameter for non-ferrous metals, plastics and other materials can be 30-50% larger than the original specification. The working principle of the electric drill is that the motor rotor of an electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and working operation, and drives the operating device through the transmission mechanism, which drives the gears to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better.

[0003] There are various types of drill guns, among which handheld drill guns are more common in daily life. Some existing handheld drill guns are only held by the handle of the drill gun itself when in use.
