Problems solved by technology

[0004] However, although there are multiple working head installation methods in the current multi-function machine, some structures in these installation methods still can continue to move along the previous mode during the installation process of the working head in some structures in these installation methods, which may easily cause the structure that has been matched to fail again. Disengagement, so that the process of disassembling and assembling the working head cannot be carried out normally

specific Embodiment approach 1

[0048] figure 1Shown is the multifunction machine 30 in this embodiment. This multifunctional machine 30 has a housing 32, an output shaft 34 extending from the inside of the housing 32, a working head 36 installed at the end of the output shaft 34, and a clamping device for fixing the working head 36 on the end of the output shaft 34 38. The clamping device 38 includes a clamping unit 40 and an operating assembly 42 , wherein the clamping unit 40 is used to clamp the working head 36 in the axial direction 41 , and the operating assembly 42 is used to drive the clamping unit 40 . The axial direction 41 extends substantially parallel to the axis X1 of the output shaft 34 .

[0049] When the multi-function machine 30 is working, the output shaft 34 performs a rotational and oscillating motion around its own axis X1, thereby generating a large abrupt torque along the two oscillating directions. Therefore, a very large axial clamping force is required to ensure that the above-m...

specific Embodiment approach 2

[0094] like Figure 10 As shown in the figure, the second embodiment of the present invention provides a multifunctional machine 200, which is the same as the multifunctional machine 30 in the first embodiment, including a housing 32 and an output shaft 34 extending from the inside of the housing 32 , the working head 36 installed at the end of the output shaft 34 , and the clamping device 238 for fixing the working head 36 at the end of the output shaft 34 . The clamping device 238 includes a clamping unit 40 and an operating assembly 242 , wherein the specific structures and principles of the clamping unit 40 and the operating assembly 242 are basically the same as those of the first embodiment, and the following description will mainly focus on the structures that differ from the first embodiment.

[0095] See Figure 11 The difference between this embodiment and the first embodiment is the installation position of the elastic element 226 disposed between the installation ...

specific Embodiment approach 3

[0110] Figure 17 to Figure 20 It is the third embodiment of the present invention. See Figure 17 and Figure 18 , the third embodiment provides a multifunctional machine 300, which is basically the same as the multifunctional machine 30 in the first embodiment, including a housing 32, an output shaft 34 extending from the inside of the housing 32, and an output shaft 34 installed on the output shaft 34. The working head 36 at the end and the clamping device 338 for fixing the working head 36 on the end of the output shaft 34 .

[0111] In this embodiment, see Figure 17 and Figure 18 , the clamping device 338 includes a clamping unit 340 and an operating assembly 342, wherein the basic principle of the clamping unit 340 and the operating assembly 342 is the same as that of the first embodiment, but the specific structure is different from the first embodiment.

[0112] The operating assembly 342 includes an operating member 368 and a driving member 370 . The operating...

Abstract

The invention discloses a handheld tool and a clamping device thereof. The clamping device of the handheld tool comprises an installation seat, a clamping unit, an operation assembly and a stop mechanism, wherein the clamping unit is used for fixing a work head in the axial direction; the operation assembly comprises an operation part and a driving part, and the operation part is movably connected with the installation seat, thereby driving the driving part to be matched with and break away from the clamping unit selectively in an operationable mode; the stop mechanism is arranged between the installation seat and the operation part; and when the driving part is matched with the clamping unit, the stop mechanism restrains the driving part from breaking the matching with the clamping unit. The handheld tool is provided with the stop mechanism, guarantees smooth dismounting and mounting of the work head, and avoids the situation that in the dismounting and mounting process of the work head, the operation part moves further, the driving part breaks the matching with the clamping unit, and the work head can not be dismounted or mounted normally.

Description

technical field [0001] The invention relates to a hand-held tool and its clamping device. Background technique [0002] The multi-function machine is a common hand-held tool in the industry. Its working 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 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] Chinese Published Patent Application No. CN101780668A discloses a multifunctional machine, which includes a motor, the motor shaft of which is connected to an eccentric pin, and a bearing is sheathed on the eccentric pin, thereby forming an eccentric wheel structure. When the motor shaft rotates, the eccentric wheel structure can rotate eccentrically around the axis of...
