As shown in Figure 5,6, above-mentioned Handleset 3 is used to hold head adjustable mechanism, while the utility model for operator
The disengaging that buckle 4 with head 1 can be also realized by rotating handle component 3, is realized by rotation convenient for head 1 and is nodded.
Specifically, the other end of Handleset 3 from cover board 2 protrudes into cover board 2, and is pivotally connected with cover board 2, buckles simultaneously
4 with 3 phase of Handleset be clamped, Handleset 3 rotate when, can drive buckle 4 along Handleset 3 axial direction, realize with head 1 into
Row engaging or separation.
In order to realize the clamping of buckle 4 with Handleset 3, the part that Handleset 3 protrudes into cover board 2 is set with connection ring
6, flange 61 is provided in connection ring 6, and fastener 42 leans with flange 61.To when Handleset 3 is axially transported along its own
When dynamic, buckle 4 can be pushed to separate with 12 phase of card slot by the flange 61 of connection ring 6.At this point, being provided with energy on fastener ontology 41
Enough catch on the bending structure 47 of the flange 61.
To when Handleset 3 acts, rely on thereon based on the interaction relation between buckle 4 and Handleset 3
Connection ring 6 realize buckle 4 and card slot 12 between clutch.
As shown in fig. 7, in one embodiment, Handleset 3 is acted in a rotative pattern, buckle 4 and card are realized
Clutch between slot 12.Wherein, the rotation mode refers to that Handleset 3 carries out rotation by shaft of own axes.At other
In embodiment, the technical concept based on the utility model realizes identical technical effect using other manner of execution, by this
The protection scope of utility model is covered.
Specifically, Handleset 3 includes: handle 31 and rotary body 32, and one end of handle 31 is fixedly connected with rotary body 32,
The other end of rotary body 32 from cover board 2 protrudes into cover board 2, and is pivotally connected with cover board 2.When for the rotation of Handleset 3, simultaneously
It is axially moved, limited post 321 is provided on rotary body 32, be provided in the inner sidewall of cover board 2 for the sliding of limited post 321
Inclined-plane.To which when Handleset 3 rotates under external force, limited post 321 can be slided along above-mentioned inclined-plane, and certainly along axial direction
The one end on inclined-plane slides into the other end, is moved with driving the buckle 4 to link with it to synchronize along axial direction.
As shown in figure 8, in one embodiment, inclined-plane is by being set to the interior sidewall surface institute of the sliding slot 24 of 2 inside of cover board
It is formed, sliding slot 24 can be special-shaped slot.Specifically, above-mentioned sliding slot 24 is surrounded by the convex ribs for being set to 2 inside of cover board.It is preferred that
Ground, sliding slot 24 are "eight" shape or L shape.When sliding slot is "eight" shape, the sliding slot 24 of "eight" shape has both ends and centre
For three limit points, limited post 321 can be moved between above three limit point, so set, 3 bidirectional rotary of Handleset
Turn that the unlock between buckle 4 and head 1 can be achieved.
In order to improve the stability of the driving unlock of Handleset 3, rotary body 32 includes left-handed transfer part and dextrorotation transfer part,
In, left-handed transfer part and dextrorotation transfer part are provided with limited post 321, are correspondingly arranged on the inside of cover board 2 there are two sliding slot 24.
Alternatively, above-mentioned Handleset 3 can be also driven by way of stretching, so that buckle 4 is blocked with head 4
It closes or separates.Specifically, the Handleset 3 includes: handle.Described handle one end is connected with the buckle, so that
Interaction relation is formed with buckle.To which when pulling handle, the handle drives buckle to be axially distant from head, and head 1 can at this time
It is freely rotated.When reversed driving handle, buckle can be driven to engage again with head.
Again as shown in Figure 1, being based on head adjustable mechanism 100 as described above, the utility model also provides a kind of application
The hand held electric tool 200 of the head adjustable mechanism, the hand held electric tool 200 include: work head 201 and institute as above
The head adjustable mechanism 100 stated.Wherein, the work head 201 is installed on the head 1.It, can by the adjusting to head 1
The operating angle of work head 201 thereon is adjusted together simultaneously, so that work head 201 obtains suitable operating angle,
Facilitate the use of hand held electric tool.The work head 201 can be moving head, trim saw, shrub and hedge trimmer etc..
Conceived based on identical utility model, the utility model additionally provides a kind of head adjusting method.The adjusting side
Head in method is a kind of head of hand held electric tool.At this point, the handle of hand held electric tool passes through a buckle and machine
Head phase clutch.Above-mentioned head adjusting method includes the following steps:
The handle for driving hand held electric tool, when driving handle in a rotative pattern, handle drives buckle along handle
Axially away from head, head is in the unlocked state, and control head opposite handle is rotated to demand position, reversely rotates handle, hand
The dynamic buckle of grip strip, axially adjacent to head, makes buckle fasten with head along handle, realizes that head adjusts the fixation of angle.
In another technical solution, the handle of hand held electric tool is driven, when with stretching mode driving handle, handle
Drive buckle along handle axially away from head, head is in the unlocked state, and control head opposite handle is rotated to demand position,
Reversed driving handle, handle drive buckle, axially adjacent to head, buckle to be made to fasten with head along handle, realize that head is adjusted
The fixation of angle.
In conclusion the electric hand tool of the utility model drives buckle de- with head by rotating handle component
From, convenient for head by rotate realize nod, operate it is more convenient
