Embodiment 1

[0051] figure 1 It is a structural schematic diagram of a circular saw blade with a working head, refer to figure 1 As shown, the circular saw blade 2 is installed on the output shaft of the power tool through the working head 1 (not shown). Since the saw blade 2 is a consumable part, the saw blade 2 needs to be frequently disassembled from the working head 1 for replacement The new saw blade 2, in this embodiment, provides an installation method in which the circular saw blade 2 is installed on the working head 1, refer to figure 1 As shown, the working head 1 includes a first installation part 4, wherein the first installation part 4 is fixed on the shaft end of the output shaft of the power tool (not shown); the second installation part 3 is sleeved on the On the shoulder (not shown) of the output shaft of the power tool; the fixing part 5 is used to connect the circular saw blade 2 . In this embodiment, the first installation part 4 is arranged on the upper end of the se...

Embodiment 2

[0059] image 3 A structural schematic diagram of a strip saw blade with a working head is provided, refer to image 3 As shown, the saw blade 2 is mounted on the power tool output shaft (not shown) through the working head 1. The working head 1 includes a first mounting part 4, a second mounting part 3 and a fixing part 5, and is a whole. The first The mounting part 4 is arranged on the upper end of the second mounting part 3, and is combined with the second mounting part 3, and the second mounting part 3 is connected with the fixing part 5, and is combined into one, and the fixing part 5 is arranged on the second mounting part 3 The lower end of the first mounting part 4 is sleeved on the shaft end of the output shaft of the power tool; the second mounting part 3 is a hollow structure inside, which is used to connect the shoulder of the output shaft of the power tool. In this embodiment, the fixed part 5 includes a fixed installation part 51 connected to the second installa...

Embodiment 3

[0067] Figure 4 It is a structural schematic diagram of the third embodiment of the working head. refer to Figure 4 As shown, the working head 1 comprises a first mounting portion 4, a second mounting portion 3, and a fixing portion 5. The fixing portion 5 is circular, and several bolt holes 6 are provided on the edge of the fixing portion 5, and the working head 1 passes through the bolts. The holes 6 are connected to the saw blade 2 , wherein the bolt holes 6 are equidistantly evenly distributed on the outer circumference of the fixing portion 5 .

[0068] The center of the first mounting part 4 is provided with a circular central mounting hole 7 , and at least four mounting grooves 9 are evenly and symmetrically distributed on the outer circumference of the central mounting hole 7 . The working head 1 can be installed on the output shaft of the power tool through the clamping connection of the installation groove 9 .

[0069] The first installation hole 8 is also provi...

Abstract

The invention relates to a saw blade working head, an operation tool with the working head and a mounting method. The saw blade working head which can be arranged on a power tool output shaft comprises a mounting part matched with the power tool output shaft, a fixing part which is fixedly connected with a saw blade, wherein the mounting part comprises a first mounting part arranged at the shaft end of the power tool output shaft, and a second mounting part sheathed on a shaft shoulder of the power tool output shaft; the first mounting part is used for realizing fixed connection with the power tool output shaft; and the second mounting part is used for increasing a contacted surface between the saw blade working head and the power tool output shaft, and increasing the torsion between the working head and the power tool output shaft. The saw blade working head, the operation tool with the working head and the mounting method disclosed by the invention have the beneficial effects that the power tool output shafts and the saw blades with different types are adapted, the detaching and mounting of the power tool output shaft and the working head can be quickly performed, and simple assembly and replacement of the working head, the power tool output shaft and the saw blade is realized, so that the working time is saved and the efficiency is improved.

Description

technical field [0001] The present invention relates to a working head for a saw blade, in particular to a working head for power tool output shafts adapted to different joints, a working tool with the working head and their installation method. Background technique [0002] The multi-function machine is a common hand-held oscillating power tool. Its principle is that the output shaft swings around its own axis. Therefore, when the user installs different working heads on the free end of the output shaft, such as a straight saw Blades, circular saw blades, triangular abrasive discs, and shovel-type scrapers can realize a variety of different operating functions, such as sawing, cutting, grinding, scraping, etc., to suit different work needs. [0003] The working principle of the multi-function machine is: a motor driver is installed in the body of the multi-function tool, and the eccentric output shaft installed in the spherical bearing is driven by the shift fork to make an...
