specific Embodiment approach 1

[0088] see image 3 and Figure 4 , a swing power tool, specifically a multifunctional machine 100, which has a housing 10, the housing 10 includes a longitudinally extending housing 11, connected to the front end of the housing 11 (with figure 1 The middle right side is defined as the front end) of the head shell 12 and the output shaft 13 extending from the head shell 12 . Wherein, a motor 14 is arranged inside the casing 11 , and a driving shaft 141 for rotating motion extends laterally from the motor 14 . A switch 111 is installed outside the casing 11 for controlling the motor 14 to be turned on or off. The head case 12 includes a horizontal portion 121 connected to the casing 11 and disposed transversely, and a vertical portion 122 substantially vertically extending downward from an end of the horizontal portion 121 . The output shaft 13 is arranged in the vertical direction, one end of which is installed in the head shell 12, and the other end extends downward from t...

specific Embodiment approach 2

[0105] like Figure 11 and Figure 13 As shown, the multifunction machine 200 of the second embodiment of the present invention is similar in structure to the multifunction machine 100 of the first embodiment. The multifunction machine 200 includes a casing 20 , which is specifically divided into a casing 21 and a head casing 22 that are connected to each other. An output shaft 23 is housed in the head case 22 , and a motor 24 is housed in the casing 21 . The motor 24 has a drive shaft 241 substantially perpendicular to the output shaft 23 , and when the drive shaft 241 rotates, it drives the output to rotate and swing. The end of the output shaft 23 extends out of the head shell 22, and a working head 232 is installed through a fixing member 231. Driven by the output shaft 23, the working head 232 swings to realize the cutting function.

[0106] The head shell 22 includes a substantially vertical horizontal portion 221 and a vertical portion 222 , both of which are substan...

specific Embodiment approach 3

[0115] like Figure 18 and Figure 19 As shown, the casing 30 of the multifunction machine 300 in this embodiment includes a casing 31 and a head casing 32 . The end of the output shaft 33 extends out of the head shell 32, and a working head 332 is installed through a fixing member 331. Driven by the output shaft 33, the working head 332 swings to realize the cutting function. The head shell 32 is non-rotatably arranged relative to the casing 31 , and an actuator 321 is disposed thereon. The outer periphery of the head shell 32 is provided with an adjusting cover 34 that can rotate relative to the actuator 321 , and the adjusting cover 34 is screw-fitted with the actuator 321 . Rotating the adjustment cover 34 can drive the head shell 32 to move relative to the casing 31 through cooperation with the actuator 321 , so that the output shaft 33 can output different swing angles.

[0116] like Figure 19 and Figure 20 As shown, the head shell 32 includes a substantially vert...

Abstract

The invention discloses a swinging power tool, the swinging angle of which is adjustable. The swinging power tool comprises a shell, a motor, an eccentric part, an output shaft and a shifting fork, wherein the shell comprises a head shell and a motor shell which are mutually connected; the motor is contained in the motor shell and is provided with a driving shaft which makes a rotating motion; the eccentric part is installed on the driving shaft and eccentrically rotates around the axis of the driving shaft; the output shaft is contained in the head shell, can make a rotating and reciprocating swinging motion around the axis of the output shaft and is used for installing and driving a working head to work; the shifting fork is connected onto the output shaft and is matched with the eccentric part to convert the rotating motion of the driving shaft into the rotating and reciprocating swinging motion of the output shaft. The head shell can be operated to move relative to the motor shell, so that the shifting fork is driven to move relative to the eccentric part and to be matched with the eccentric part at different positions to enable the output shaft to output different swinging angles.

Description

technical field [0001] The invention relates to a power tool, in particular to a hand-held oscillating power tool. Background technique [0002] The multi-function machine is a common hand-held oscillating power tool in the industry. Its working principle is that the output shaft performs oscillating motion around its own axis. Therefore, when the user installs different working heads on the free end of the output shaft, such as straight saw blades, circular saw blades, triangular abrasive discs, and shovel scrapers, a variety of different operating functions can be realized, such as sawing, cutting, etc. , grinding, scraping, etc., to suit different work needs. [0003] specific reference figure 1 and figure 2 , an existing oscillating power tool 100' includes a casing 1', an output shaft 2' extending from the casing 1', a motor 11' set in the casing 1' and a motor driven by the motor 11'. Main axis 4'. One end of the main shaft 4' is connected with a connecting shaft...
