Embodiment 1

[0033] Such as Figure 1 to Figure 5 As shown, the present embodiment is an electric tool, specifically, a hand-held electric tool, including a main body 1 and an installation head 11 arranged at the front end of the main body 1, and the side of the installation head 11 part protrudes from the output shaft 111, a motor is provided in the main body 1 of the fuselage, and the motor drives the output shaft 111 to rotate. The installation head 11 is detachably connected with a replaceable processing assembly, and the processing assembly includes an angle grinding assembly 2 or a chain saw Component 3, in actual use, if it is necessary to use the electric tool as an angle grinder, install the angle grinder assembly 2 on the installation head 11, and when it is necessary to use the electric tool as a chain saw, you can install the angle grinder assembly 2 Remove and install the chain saw assembly 3 on the mounting head 11. In the entire power tool, the main body 1 of the fuselage is...

Embodiment 2

[0046] Such as Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the sprocket 31 is not fixed on the output shaft 111 by means of a fixing nut, but is fixed on the output shaft 111 by a cotter pin. A pin hole is provided. When the second positioning hole 311 of the sprocket 31 is matched with the non-circular positioning portion 1110 , the cotter pin 15 is inserted into the pin hole, and the sprocket 31 is locked on the output shaft 111 by the cotter pin 15 .

Abstract

The invention discloses a multifunctional electric tool, and belongs to the field of electric tools. The multifunctional electric tool comprises a machine body main body and a mounting head which is arranged at the front end of the machine body main body, wherein an output shaft extends out from the side part of the mounting head; the mounting head is detachably connected with a replaceable processing component; the processing component comprises an angle grinder component or a chain saw component; two connecting parts are arranged on the mounting head; and the angle grinder component and the chain saw component are separately mounted on the corresponding connecting parts in a matched mode, and are in transmission connection with the output shaft. The multifunctional electric tool has the advantage of serving several purposes, being capable of meeting angle grinder cutting and meeting chain saw cutting, increasing a usage rate of the machine body, and savig cost.

Description

[0001] 【Technical field】 [0002] The invention relates to a multifunctional electric tool, which belongs to the field of electric tools. [0003] 【Background technique】 [0004] There are many types of power tools on the market, and the functions are also diverse. However, the driving systems of many power tools are common, but the working heads installed are different. For example, angle grinders and electric chain saws are actually the same. It is a cutting tool. The working principle of the angle grinder is to drive the saw blade to rotate through the motor to cut the workpiece, but when cutting wood, the cutting depth is small. The working principle of the chain saw is to drive the transmission mechanism through the power device, and the saw chain is driven by the transmission mechanism to cut. The cutting depth is relatively deep, and it is usually used for pruning or forestry work, such as tree felling, pruning and truncation, etc. Due to the different cutting methods, ...
