Embodiment Construction

[0043] The invention relates to a power tool, in particular to a structure and a method for installing a working head on the power tool. Among them, the power tools can be electric circular saws, small electric circular saws, swing machines, angle grinders, miter saws, etc.; and the working head can be a straight saw blade, or a circular saw blade, sand disc, scraper, etc. other accessories.

[0044] In this embodiment, a small electric circular saw is cited to illustrate the creative concept of the present invention.

[0045] see figure 1 with figure 2 , a small electric circular saw 30, including a housing 32, a motor 34 accommodated in the housing 32, a transmission assembly 36 connected to the motor 34 for power transmission, driven by the transmission assembly 36 and used for installing a circular saw blade 38 output shaft 40 (such as image 3 shown). In the description of the present invention, unless otherwise indicated, directional terms, such as front, rear, lef...

Abstract

The invention provides an operation method for mounting and dismounting a working head on and from a power tool. The power tool comprises an output shaft, a fastening piece, a locking piece and a driving piece, wherein the output shaft is used for mounting the working head and driving the working head to work; the fastening piece is used for fixing the working head on the output shaft; the locking piece is used for locking and releasing the working head and moves between the locked position and the released position; and the driving piece is used for being movably arranged on the output shaft. The operation method comprises the following steps: a) pressing the driving piece to drive the locking piece to move so as to release the fastening piece; b) taking out the working head. The operation method has the benefits that an operator is only required to press the driving piece to drive the locking piece to move so as to release the fastening piece, so that the fastening piece can be easily dismounted from the output shaft, and the convenience for operation is improved.

Description

technical field [0001] The invention relates to an operation method for detaching a working head from a power tool. Background technique [0002] A working head in a power tool, such as a circular saw blade, is typically driven by a rotary output shaft coupled to the power tool's motor. In many cases, circular saw blades have a hole through the center that accommodates the output shaft. One end of the output shaft where the circular saw blade is installed is provided with an internal thread. When installing, place the saw blade on the output shaft, extend the fastening bolt through the hole on the saw blade into the thread of the output shaft, and then tighten the fastening bolt with a wrench to fix the circular saw blade on the output shaft ; Similarly, loosen the fastening bolt by a wrench, and take off the fastening element from the output shaft to take off the circular saw blade. It can be seen that the traditional structure of installing the working head on the outpu...
