Embodiment Construction
[0016] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.
[0017] Such as figure 1 , figure 2 As shown, a hand electric drill includes a casing 2, a power cord 4 located in the casing 2, a pressing plate 6, a switch 8, a stator 10, a rotor assembly 12 and a large gear assembly 14, and the power cord 4 passes through the pressing plate 6 and The gap between the casings 2 is to press the power cord 4 tightly through the pressure plate 6 to avoid shaking and twisting of the power cord 4 and avoid damage to the power cord 4. The rotor assembly 12 includes a rotor 16, a first bearing 18 and a second bearing 20 , the rotor 16 passes through the stator 10, and two carbon brush assemblies 22 are arranged b...

The invention relates to an electric hand drill. The electric hand drill comprises a shell, a power line, a pressing plate, a switch, a stator, a rotor assembly and a large gear assembly, wherein the power line, the pressing plate, the switch, the stator, the rotor assembly and the large gear assembly re arranged in the shell. The power line penetrates through the gap between the pressing plate and the shell. The rotor assembly comprises a rotor, a first bearing and a second bearing. The rotor penetrates through the stator. Two carbon brush assemblies are arranged between the rotor and the stator. Each carbon brush assembly comprises a brush frame, a carbon brush and a connecting line. The power line, the stator and the connecting lines are all connected with the switch. The large gear assembly comprises a large gear, a third bearing, a fourth bearing and an output shaft fixed to the large gear. The large gear is engaged with the rotor. The first bearing, the second bearing, the third bearing and the fourth bearing are all fixed to the shell. The two ends of the rotor penetrate through the first bearing and the second bearing correspondingly. The two ends of the output shaft penetrate through the third bearing and the fourth bearing correspondingly. A drill chuck is fixed to the output shaft. The electric hand drill is compact in structure, convenient to assemble and high in working efficiency.
Description
technical field [0001] The invention relates to an electric tool, in particular to a hand electric drill. Background technique [0002] The current electric hand drill mainly adopts two methods, one is to use AC power, and the other is to use DC battery, which is a hand-held electric tool that drives the drill bit to rotate and drill holes through AC power or batteries, and is widely used in construction and decoration. , furniture and other industries. However, the drill chuck of the existing electric hand drill is easy to loosen during the vibration process, which affects the drilling quality and the work efficiency is low. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a hand electric drill with simple structure. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a hand electric drill, including a casing, a power cord, a pressure plate, a switch, a stator...
