Problems solved by technology

However, there are many types of accessories on the market, and they cannot be used universally on all power tools.
In addition, the disassembly and installation of accessories are relatively complicated, which causes great inconvenience to users.
Most importantly, when a deep hole needs to be drilled, at the beginning of the drilling, the attachment shakes more seriously, and the drilling work cannot be performed well

Embodiment 2

[0178] The working principle and working process of the linkage mechanism in the second embodiment are similar to those in the first embodiment, and will not be repeated here!

[0179] The operation method and operation method of the electric drill of the second embodiment are basically similar to the first embodiment, the method of the first embodiment can be referred to, only need to make appropriate adjustments, and will not be repeated here!

Embodiment 3

[0181] The linkage mechanism of Embodiment 3 also includes a first acting part arranged on the main body, a second acting part arranged on the abutting bracket, and a handle arranged on the handle so that the first acting part and the second acting part can react relative to the handle. Reversing unit towards motion.

[0182] see Figure 10 , the reversing unit is a guide wheel 84 arranged on the handle 2, and a flexible connecting piece that goes around the guide wheel. The flexible connector includes a first flexible connector 83a and a second flexible connector 83b, the first flexible connector 83a walks around the guide wheel 84 from the front end, and contacts with the rear half of the guide wheel 84; Walk around guide wheel 84 behind, contact with the front half wheel surface of guide wheel 84.

[0183] The first action part is the first fixing unit for fixing the flexible connector on the base part 112 of the main body 1, specifically including the first fixing part 8...

Embodiment 4

[0196] The linkage mechanism of Embodiment 4 also includes a first action part set on the main body 1, a second action part set on the abutting bracket 3, and a handle which can make the first action part and the second action part relative to the handle. Reverse unit for reverse movement.

[0197] see Figure 11-12 , the first action part is the first tank body 91a that is fixed on the main body and extends axially; the second action part is the second tank body 91b that is fixed on the support bracket and extends axially; the reverse unit includes the first piston rod 93a and a second piston rod 93b, a pressure transmission medium, and a storage tank (not shown) for storing the pressure transmission medium. The first piston rod 93a and the second piston rod 93b are fixed on the handle and face opposite.

[0198] The first piston rod 93a is embedded in the first tank body 91a, and is sealingly connected with the first tank body 91a to form the first cavity 92a; the second p...

Abstract

The invention discloses a power tool and an operation method thereof. The power tool comprises a main body, a motor, a handle and a propping bracket and further comprises a link mechanism, wherein the main body is provided with an output shaft for diving a working head to rotate; the motor is used for driving the output shaft to rotate; the handle is movably connected with the main body; and the link mechanism is arranged among the main body, the handle and the propping bracket and enables the main body and the propping bracket to simultaneously move towards or away from each other relative to the handle in the axial direction of the output shaft. According to the power tool provided by the invention, since the main body and the propping bracket move away from each other relative to the handle to reduce the distance for which the propping bracket extends out of the handle, the stability of the propping bracket is enhanced.

Description

technical field [0001] The invention relates to a power tool, in particular to a drilling power tool. [0002] The invention also relates to a method of operating a power tool. Background technique [0003] Existing drill-type hand-held power tools generally include electric drills, impact drills and electric screwdrivers. The electric drill is used to drill holes on the workpiece. During the operation, the drill shaft continuously rotates. [0004] In order to better process holes on the workpiece, it is necessary to additionally install a resist bracket on the power tool to help resist the workpiece. However, there are many types of accessories on the market, which cannot be applied to all power tools. In addition, the disassembly and installation of the accessories are relatively cumbersome, which causes great inconvenience to users. The most important thing is that when a deeper hole needs to be drilled, at the beginning of the drilling, the accessories shake more se...
