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.
More importantly, when it is necessary to drill a hole with a long depth, the accessory shakes a lot at the beginning of drilling, which will have a certain impact on the drilling work

Embodiment 2

[0219] The operation method of the electric drill of the second embodiment is basically similar to that of the first embodiment, and will not be repeated here!

[0220] Figure 13a -b, Figure 14a -b and Figure 15a -e shows the third embodiment of the present invention. The main difference between the third embodiment and the first embodiment is the depth positioning mechanism.

Embodiment 3

[0221] The depth positioning mechanism of the third embodiment achieves the purpose of depth positioning by preventing the linkage mechanism from moving. Specifically, the depth positioning mechanism is arranged between the linkage mechanism and the handle.

[0222] More specifically, in this embodiment, the depth positioning mechanism prevents the movement of the reverse unit of the linkage mechanism; furthermore, it limits the rotation of the gear.

[0223] In the third embodiment, the gears of the linkage mechanism are also arranged in the horizontal plane.

[0224] Specifically, the depth positioning mechanism includes a rotation limiting component, which can limit the rotation of the gear when the preset depth is reached, so that the host and the supporting bracket cannot move relative to each other, thereby realizing the fixed depth.

[0225] see in conjunction Figure 13a -b, Figure 14a -b, the rotation limiting assembly includes a stopper 68 arranged on the gear 53 ...

Embodiment 4

[0239] The linkage mechanism of Embodiment 4 also includes a first action part set on the main body, a second action part set on the abutting bracket, and a handle which can make the first action part and the second action part react relative to the handle. Reversing unit towards motion.

[0240] see Figure 16a -b, the reverse unit is a guide wheel 84 arranged on the handle 2, and a flexible connecting piece bypassing 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.

[0241] 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 81a for fixing the first flexible con...

Abstract

The invention discloses a power tool and an operating method thereof. The power tool comprises a main body, a motor, a handle and a resisting bracket, wherein the main body is provided with an output shaft for driving a working head to rotate, the motor drives the output shaft to rotate, the handle is movably connected to the main body, and the main body and the resisting bracket move axially in opposite directions or reverse directions relative to the handle at the same time. The power tool further comprises a depth positioning mechanism. When the resisting bracket axially moves backward to a predetermined position relative to the handle, the depth positioning mechanism limits the movement of the resisting bracket and the main body in opposite directions. According to the power tool disclosed by the invention, as the main body and the resisting bracket move axially in opposite directions or reverse directions relative to the handle, the length of the resisting bracket, extending out of the handle, is relatively small, so that the stability of the resisting bracket is enhanced.

Description

technical field [0001] The present invention relates to a 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. What's more, when it is necessary to drill a hole with a long depth, at the beginning of drilling, the accessory shakes a lot, which affects the drilling work to a cert...
