Description

Mower

Technical field

The utility model relates to electric tool, relates in particular to a kind of mower.

Background technology

In the prior art, instrument can have mower, brush saw, bar chain saw, bar shrub and hedge trimmer etc.Usually all need spinfunction, can realize the function of rotation because manufacturer need consider each connecting portion, so that help different azimuth and difference in functionality use, intensity and the function of examining rotating part simultaneously again need satisfy machine requirement.For example, electric tools such as mower all have trimming function, so this type of machine is necessary to have spinfunction, so that help different azimuth and difference in functionality use, so this type of needs spinfunction.

Mower of the same type in the market, make manual have button, push-button type locking, button and push button are all because the characteristics of each self-structure, but the contact area of button or push button is little or be embedded, during use, the operator need concentrate efforts on a part and overcome reaction force and come actuation button or push button, as singly referring to operation etc., fails to consider that operator's hand strength is concentrated and the operation discomfort that causes.

The utility model content

The technical problems to be solved in the utility model is: a kind of simple to operation, mower that driving head rotates easily is provided.

In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of mower, comprise handle, tube connector and driving head, described handle is connected with driving head by tube connector, be provided with adapter sleeve between described tube connector and the driving head, this adapter sleeve is fixedlyed connected with tube connector, described adapter sleeve and described driving head are rotationally connected, fix by locking device between described adapter sleeve and the driving head, described locking device comprises and the fixing Rotary Connection block of driving head, be positioned at the adapter sleeve latch segment corresponding and drive the button that latch segment slides with Rotary Connection block, be provided with elastic component between described latch segment and the adapter sleeve, described button exposes to adapter sleeve.

According to another embodiment of the present utility model, mower comprises further and is evenly distributed with some draw-in grooves on the described Rotary Connection block that described latch segment is provided with the projection corresponding with draw-in groove.

According to another embodiment of the present utility model, mower comprises that further described latch segment one end is provided with the connecting hole that connects with Rotary Connection block, the described latch segment other end is provided with the square groove with the Rotary Connection block clamping, and described Rotary Connection block is provided with flat corresponding with square groove.

According to another embodiment of the present utility model, mower comprises that further the both sides of described latch segment are distributed with overlap, is provided with the chute corresponding with overlap in the described adapter sleeve.

According to another embodiment of the present utility model, mower comprises that further described elastic component is a spring.

The utility model has solved the defective that exists in the background technology, and the utility model helps the user when operating, and can make full use of whole hand strength, avoids firmly too concentrating and causes that operation is uncomfortable.

Embodiment

With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

As shown in Figure 1, a kind of mower, comprise handle 1, tube connector 2 and driving head 3, described handle 1 is connected with driving head 3 by tube connector 2, be provided with adapter sleeve 5 between described tube connector 2 and the driving head 3, this adapter sleeve 5 is fixedlyed connected with tube connector 2, described adapter sleeve 5 is rotationally connected with described driving head 3, fix by locking device between described adapter sleeve 5 and the driving head 3, described locking device comprises the Rotary Connection block of fixing with driving head 36, be positioned at the corresponding latch segment 7 of adapter sleeve 5 and Rotary Connection block 6 and drive the button 8 that latch segment 7 slides, be provided with elastic component 9 between described latch segment 7 and the adapter sleeve 5, described button 9 exposes to adapter sleeve 5, can make full use of whole hand strength driving head 3 is carried out the rotational angle adjustment by pushing button 8.Described elastic component 9 is preferably spring.

As shown in Figure 2, be evenly distributed with some draw-in grooves 61 on the Rotary Connection block 6, the preferred draw-in groove 61 of the utility model is 4, and described latch segment 7 is provided with the projection 71 corresponding with draw-in groove 61.And latch segment 7 one ends are provided with the connecting hole 72 that connects with Rotary Connection block 6, described Rotary Connection block 6 can rotate in connecting hole 72, described latch segment 7 other ends are provided with the square groove 73 with Rotary Connection block 6 clampings, described Rotary Connection block 6 is provided with flat 62 corresponding with square groove 73, when flat 62 snap in square groove 73 after, latch segment 7 is fixing with Rotary Connection block 6.

As shown in Figure 3, move in adapter sleeve 5 for ease of latch segment 7, the both sides of latch segment 7 are distributed with overlap 75, are provided with the chute 51 corresponding with overlap 75 in the described adapter sleeve 5.

Latch segment 7 is connected with button 9 and is installed on the adapter sleeve 5, button 9 parts expose, and can press operation, press button 9 latch segment 7 is slided in adapter sleeve 5, and latch segment 7 resets by spring after unclamping external force, after resetting promptly with adapter sleeve 5 relative fixed.This adapter sleeve 5 is connected back and driving head 3 connections with Rotary Connection block 6, Rotary Connection block 6 self is fixedlyed connected with driving head 3.Driving head 3 can rotate after latch segment 7 and Rotary Connection block 6 releasings are spacing each other relatively with adapter sleeve 5.Button 9 parts expose to outside the adapter sleeve 5, pressing button 9 can make latch segment 7 break away from Rotary Connection block 6, remove spacing, can be rotated this moment to driving head 3, release button 9 after driving head 3 rotates to certain angle, latch segment 7 can be resetted and lock Rotary Connection block 6 at no external force effect lower spring, as shown in Figure 4, because Rotary Connection block 6 is fixedlyed connected with driving head 3, so this moment, driving head 3 was promptly simultaneously limited, and latch segment 7 with sliding motion can only take place in adapter sleeve 5 after button 9 is connected, after latch segment 7 resets, adapter sleeve 5 also thereupon with driving head 3 relative fixed in this position.Press button 9 once more, and reverse rotation driving head 3, can make driving head 3 and adapter sleeve 5 relative fixed in the another location, as shown in Figure 5.The utility model is realized relative position conversions different between driving head 3 and the adapter sleeve 5 with this, and then can switch between different duties.

With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
