Problems solved by technology

[0002] In people's life, various tools are used, for example, in home life, tools such as hair dryers and vacuum cleaners are used, in production and life tools such as ground drills and mixing heads are used, and in gardening life For tools such as lawnmowers and circular saw heads, the tool heads of these tools are all fixed and driven by the same fixing method. The tool heads with different torques cannot match the same main machine head, and the same main machine head cannot be adaptively driven to different torques. The function of the tool head
Moreover, in the prior art, due to this single adaptation principle, when either the tool head or the host head fails, a new tool needs to be repurchased, which undoubtedly increases the cost of production and living

Embodiment 1

[0044] In order to solve the problems in the prior art, the present invention provides a Figure 1 to Figure 4 The hand-held machine tool 100 shown includes a main body housing 1, a driving device 3 arranged in the main body housing 1, and the main body housing 1 is provided with Figure 5 to Figure 7 or Figure 8 to Figure 12 The tool head mounting part 11 of the shown tool head 200 is form-locked and / or force-locked; When the tool head 200 is installed on the tool head mounting part 11, the tool head 200 can realize form-locking and / or force-locking connection by means of the first mounting component 13 and the first locking component 21, so that the driving device 3 can be connected with a first Maximum torsional strength to drive the tool head 200 to work;

[0045] When the tool head 200 including the second locking assembly 22 is installed on the tool head mounting part 11, the tool head 200 can realize form-locking and / or force-locking connection by means of the second...

Embodiment 2

[0073] Specifically, in the above-mentioned embodiment 1, only the implementation manner in which the first locking assembly 21 is set on the tool head 200 is introduced. Two embodiments of the locking assembly 22.

[0074] Specifically, such as Figure 1 to Figure 4 As shown, the hand-held power tool 100 includes a main body housing 1 and a driving device 3 located in the main body housing 1. The main body housing 1 includes an operating handle 12 extending toward one end of the main body housing 1 for holding and a The other end of the housing 1 extends a tool head mounting portion 11 . The tool head mounting portion 11 includes a first side plate 111 and a first top plate 112 and a first bottom plate 113 disposed at two ends of the first side plate 111 . Preferably, the first side panel 111 is a curved surface.

[0075] Specifically, the tool head installation part 11 is used to install such as Figure 8 to Figure 12 As shown in the tool head 200, the first mounting ass...

Embodiment 3

[0096] Further, in the above-mentioned embodiment 1 and embodiment 2, only one locking assembly is provided on the tool head 200. In other feasible solutions, the first locking assembly 21 and the second locking assembly can also be provided on the tool head 200 at the same time. Components 22 , and selectively engage with the first mounting component 13 through the first locking component 21 , and be locked with the second mounting component 14 through the second locking component 22 . Therefore, when two kinds of locking components are provided on the tool head 200 , an adapted connection mode can be selected based on the force on the tool head 200 itself, so as to achieve a stable connection between the tool head 200 and the hand-held power tool 100 .

[0097] It can be understood that when the first locking component 21 and the second locking component 22 are arranged on the same tool head 200 at the same time, each structure of the first locking component 21 and each struc...

Abstract

The invention relates to the technical field of functional tools, in particular to a handheld machine tool which comprises a main machine shell and a driving device, and when a tool head is installed on the machine tool, the tool head achieves shape locking and / or force locking connection through a first installation assembly on the machine tool and a first locking assembly on the tool head. The tool head is driven by the driving device to work at the first maximum torsional strength; alternatively, the tool head is connected in a form-fitting and / or force-fitting manner by means of a second mounting assembly on the machine tool and a second locking assembly on the tool head, so that the tool head is driven by the drive device to work with a second maximum torsional strength. By providing at least two connection modes, matching with tool heads with different working torques is achieved, so that the machine tool drives different tool heads to work with different torsional strengths, free and portable switching of the tool heads can be achieved through the multiple connection modes, diversification of tool functions is achieved, and different requirements of customers are met.

Description

technical field [0001] The invention relates to the technical field of functional tools, in particular to a hand-held machine tool and a hand-held electric tool with the machine tool. Background technique [0002] In people's life, various tools are used, for example, in home life, tools such as hair dryers and vacuum cleaners are used, in production and life tools such as ground drill bits and mixing heads are used, in gardening life tools are used For tools such as lawnmowers and circular saw heads, the tool heads of these tools are all fixed and driven by the same fixing method. The tool heads with different torques cannot match the same main machine head, and the same main machine head cannot be adaptively driven to different torques. The function of the tool head. Moreover, in the prior art, due to this single adaptation principle, when any one of the tool head or the host head fails, a new tool needs to be purchased, which undoubtedly increases the cost of production ...
