Embodiment of the present utility model employs the electric tool of the handle with switch block and actuated components.Can other different benefit of providing of apparent the various embodiments of the utility model and advantage from following describing.

Referring to figs. 1 to Fig. 3, the utility model provides a kind of electric tool 100, and it has functional unit 104.Such as when electric tool 100 is hand-push type mower, this functional unit 104 can be configured to have the mowing blade with motor driven.Preferably, functional unit 104 or electromotor are with driven by power, wherein electric tool 100 can have the electrical socket 106 for stube cable, such as, be suitable for connecting the prolongation cable that two ends have male joint and female joint respectively, and therefore electric tool 100 can be electrically connected with supply socket.Or electric tool 100 can have the cable for connecting supply socket, it is configured to be electrically connected with supply socket, or is electrically connected with supply socket by extending cable, thinks that the functional unit 104 of electric tool 100 provides electric power.Alternatively, electrical socket 106 can have difformity according to different needs (standard as the attaching plug/seat of country variant), the male joint with two pins as For the illustrated example can make the male joint of three pins into, maybe can make other pin count object public affairs/female joints into.

As shown in Figure 1 to Figure 3, electrical socket 106 can be positioned on the position of handle 102 substantial middle, and is electrically connected with functional unit 104 through cable.Handle 102 has the switch block 108 of the power supply being configured to the functional unit 104 being communicated with described electric tool 100.Preferably, switch block 108 is electrically connected with electrical socket 106, and between the electrical connection being located at electrical socket 106 and functional unit 104, therefore selectively can be communicated with according to different actuating state or the power supply of opening operation parts 104.Different actuating state examples can describe in detail later again.

Preferably, handle 102 has handle housing 110, and handle housing 110 in order to the main profile of construction handle 102, and is defined for collecting or supports the handle inner chamber of different grip member as parts such as switch block 108, actuated components 112, electrical sockets 106.As shown in Figure 1 to Figure 3, handle 102 has the horizontal handle portion 102A of the direction of operating being approximately perpendicular to electric tool 100 and is roughly parallel to longitudinal handle portion 102B of direction of operating of electric tool 100, and there is roughly symmetrical structure, when user operation electric tool 100, the selectively horizontal handle portion 102A of holds handle 102 or longitudinal handle portion 102B.In addition, handle housing 110 defines the syndeton 114 being connected to handle extension rod 130 for handle housing 110, and has applicable through the through hole utilizing screw to reinforce.Handle housing 110 usually with rigidity material as plastics, PVC or metal are made, and providing the surface of the position of user's handling can add anti skid material as the material such as rubber, silica gel, or directly cause surface as anti-skidding in hole line, grid line, asperities etc. on the surface of housing.

As shown in Figures 4 to 6, handle 102 has at least one group of actuated components 112, and is partly contained in handle inner chamber.Preferably, actuated components 112 is articulated with the support component 116 in described handle inner chamber, and can move between on-position and open position.Such as, actuated components 112 can have the hinge member 118 corresponding with support component 116, and therefore longitudinal press section 122B of actuated components 112 and horizontal press section 122A moves pivotly.Handle housing 110 has through hole, and when actuated components 112 is configured in open position, the press section 122 of actuated components 112 exposes to the periphery of handle 102 through through hole; When actuated components 112 is configured in on-position, the press section 122 of actuated components 112 at least in part retraction in handle inner chamber.Be understandable that, when actuated components 112 is configured in on-position, press section 122 moves up, and the actuation part 124 of hinge member 118 another side then can move down, and actuation switch parts 108, be therefore communicated with the power supply of functional unit 104; On the contrary, when actuated components 112 is configured in open position, press section 122 moves down, and the actuation part 124 of hinge member 118 another side then can move up, and stops actuation switch parts 108, therefore the power supply of opening operation parts 104.

Preferably, actuated components 112 has more than one press section 122, the general shape of such as actuated components 112 is corresponding with handle housing 110, and as shown in the figure as can have longitudinal press section 122B and horizontal press section 122A, therefore user can select to operate electric tool 100 with longitudinal press section 122B or horizontal press section 122A.Preferably, actuated components 112 is integrally formed, therefore no matter user operates electric tool 100 with longitudinal press section 122B or horizontal press section 122A, actuated components 112 all can responsive actuation operate to move to on-position and actuation switch parts 108, or moves to open position and stop actuation switch parts 108.Or actuated components 112 is made up of different assemblies, and draws in operation and reach to similar actuation effect mutually.Alternatively, handle inner chamber is provided with the elastomeric element 126 (as spring) for bias voltage actuated components 112, elastomeric element 126 can be used for press section 122 to be biased into the periphery exposing to handle 102 through through hole, such as when user's release imposes on the power of press section 122, elastomeric element 126 can return open position by assisted activation parts 112.Or actuated components 112 can be configured to only to utilize force of gravity to assist and get back to open position.

As shown in the figure, handle 102 has roughly symmetrical structure, and switch block 108 can be arranged at the position of the substantial middle of handle 102.Handle 102 both sides are provided with two groups of actuated components 112, provide user be located at the actuated components 112 of the left part 102L of handle when operating electric tool 100 with left-handed operation and/or be located at the actuated components 112 of right part 102R of handle with right-hand operated.As described above, the actuatable switch block 108 being located at the substantial middle of handle of actuated components 112.

Exemplarily, when user operation electric tool 100, can first prolongation cable be connected on electrical socket 106, and socket that the prolongation cable other end is connected with the mains.Then press the master switch 128 on switch block 108, the left part 102L of hands grasping handle 102 and right part 102R, and the press section 122 of simultaneously pressing left part 102L and right part 102R with start-up operation parts 104 to carry out the operation of electric tool 100.Operation horizontal press section 122A or longitudinal press section 122B can be chosen at random, because horizontal press section 122A and longitudinal press section 122B is interlock substantially with family.Be set as that bimanualness can guarantee that user's both hands are all in safe position in holds handle 102, avoid causing accident because of one-handed performance.Or switch block 108 can be arranged to allow one-handed performance, namely user can choose at random any one press section 122 of operation to start electric tool 100.When user's complete operation, user can discharge press section 122 with the power supply of opening operation parts 104.In addition, master switch 128 is also non-essential, and in some settings, the actuated components 112 that electric tool 100 can be configured to only need connect power supply and operate left part 102L and/or right part 102R is to start electric tool 100.

Therefore, after describing several embodiment, those skilled in the art will recognize that different changes, other structure, equivalent, can be used without and can deviate from essence of the present utility model.Accordingly, above description should not be regarded as the restriction to the determined the utility model scope of the claim of the application.
