The specific embodiment

In order to be illustrated more clearly in the utility model, now lift the utility model one preferred embodiment, and conjunction with figs. is elaborated.

As Fig. 1～shown in Figure 3, be the electric tool A of the utility model one preferred embodiment, it includes a tool body 1 and a battery component 2, wherein:

Tool body 1 has a main part 10, an and linking part 20 that is attached at main part 10 bottoms, because the structure of main part 10 is with generally known identical, just do not add at this and to give unnecessary details.The inside of linking part 20 is formed with an accommodation chamber 21, and as shown in Figure 3, accommodation chamber 21 forms a bottom opening 211 and a side mouth 212 respectively at the bottom and a sidepiece of linking part 20, and bottom opening 211 is interconnected with side mouth 212.Linking part 20 inside are formed with one group of rib shape member 22 that is positioned at 21 liang of side positions of accommodation chamber respectively, extending in parallel to the opposite end near side mouth 212 ends from linking part 20 respectively; Be formed with an engagement groove 221, two engagement grooves 221 on the two rib shape members 22 respectively respectively on two rib shape members 22, extend in parallel to the opposite end from a end, and the notch of two engagement grooves 221 faced mutually near side mouth 212.In addition, two engagement grooves 221 respectively two rib shape members 22 near the end face of side mouth 212 ends on form one and penetrate mouthfuls 222.Linking part 20 also has two blocks 23, lays respectively at the below of two rib shape members 22.Each block 23 has a cardinal extremity 231 and an end 232, and two ends 232 are faced mutually.Also be formed with one first guiding face 233 on each block 23, it extends towards the direction of a side direction cardinal extremity 231 of side mouth 212 from end 232.In addition, linking part 20 also has one group of power supply and connects terminal 24, is arranged in accommodation chamber 21.

As shown in Figure 2, battery component 2 includes a housing 30, two locking parts 40, two springs 50 and a battery pack 60.Wherein:

The housing 30 inner battery rooms 31 that form are used to accommodate and self-contained battery group 60; The position that corresponding power supply connects terminal 24 on the housing 30 is provided with a power output terminal 32, is used to connect the electrode of battery pack 60.Housing 30 also have an end face 33 and one group be formed on the end face 33 and cooperate two engagement grooves 221 and be provided with in conjunction with rail 34.Be parallel to each other in conjunction with rail 34, respectively have one first end 341 and one second end 342, and 2 first ends 341 are positioned at homonymy, 2 second ends 342 also are positioned at homonymy.Each has a base portion 343 and a joint portion 344, two base portions 343 for from end face 33 vertical extensions in conjunction with rail 34, and two joint portions 344 are the horizontal-extending in the opposite direction from two base portions, 343 tops respectively then; By this, can with housing 30 in conjunction with first end 341 of rail 34 towards two engagement grooves 221 penetrate mouthfuls 222, and two joint portions 344 penetrated mouthfuls 222 from two place two engagement grooves 221, housing 30 is combined on the linking part 20.In addition, have two perforation 331 on the end face 33, be positioned at two base portion 343 belows in conjunction with rail 34.Symmetrical position, housing 30 both sides forms a room 35, two rooms 35 respectively and respectively forms an opening 351 in the symmetrical position of the two side faces of housing 30, and has a through hole 352 connection battery rooms 31 on the bottom surface of each room 35.In addition, housing 30 also has two flanges 36 that protrude out along the part opening edge of two rooms 35 respectively.

Each locking part 40 has the connecting portion 43 of a press section 41, a locking part 42 and a binding press section 41 and locking part 42.Press section 41 has a body 411 and a flange 412, and body 411 generally is flat, has a lateral surface 411a and a medial surface 411b, and lateral surface 411a goes up the recess 413 that formation one is pushed for staff.Flange 412 corresponds to the flange 36 of housing 30 and outwards protrudes out from the part periphery of body 411.Connecting portion 43 is long flat strip shaped, and it has a cardinal extremity 431 and an end 432, and cardinal extremity 431 is connected on the medial surface 411b of body 411 of press section 41.Locking part 42 is a projection shape, is formed on end 432 places of connecting portion 43, and has one second guiding face 421 on the locking part 43.

Two locking parts 40 are combined on the housing 30, and wherein, two press sections 41 lay respectively in two rooms 35, and the lateral surface 411a of each body 411 is exposed at outside the opening.Two connecting portions 43 penetrate the battery room 31 from two through holes 352 respectively; Two locking parts 42 pass from two perforation 331 respectively, lay respectively at two 344 belows, joint portion in conjunction with rail 34.

Two springs 50 lay respectively in two rooms 35, on the medial surface 411b of room 35 bottom surfaces at two ends of each spring 50 difference contact place and the body 411 of press section 41.

As shown in Figure 4, and consult Fig. 1～Fig. 3, the combination of tool body 1 and battery component 2, be with battery component 2 in conjunction with first end 341 of rail 34 side mouth 212 towards joint seat 20, and wear mouthfuls 222 from two of engagement groove 221 respectively with two joint portions 344 and place two engagement grooves 221; The application of force promotes battery component 30, and two joint portions 344 are slipped in two engagement grooves 221 fully.In this process, the locking part 42 of two locking parts 40 two blocks 23 of passing through, first guiding face 233 that makes second guiding face 421 of two locking parts 42 be subjected to two blocks 23 respectively pushes away pulls, and moves to housing 30 internal direction thereby drive whole locking part 40.After the locking part 42 of two locking parts 40 is through two blocks 23, two joint portions 344 are slipped in two engagement grooves 221 fully, and two locking parts 40 return original position respectively again because of the contact of two springs 50, form mutually with two blocks 23 respectively to engage, and can stop battery component 2 to be deviate from from tool body 1.

In the time will taking off battery component 2, the press section 41 that the user can push two locking parts 40 with two singlehanded fingers thumb and forefinger or the thumb and the middle finger of one hand (for example with), drive two locking parts 42 respectively and break away from two projections 23, and the battery component 2 of application of force pulling simultaneously, two joint portions 344 are skidded off, to take out battery component 2 from two engagement grooves 221.

More than be the detailed description of the electric tool A of the utility model one preferred embodiment, introduce the advantage of electric tool A below:

One, because two engagement grooves 221 and two little in conjunction with the volume of rail 34, so the volume of tool body 1 and battery component 2 can reduce than the aforementioned instrument of commonly using effectively, helps carrying and using of electric tool A.

Two, the locking part 42 of two locking parts 40 is located at mode, the space of 344 belows, joint portion effectively can be utilized, effectively reduce the volume of battery component 2 in conjunction with 344 belows, joint portion of rail 34.

Three, two engagement grooves 221 combine with two rail 34 in conjunction with the time, the also simultaneously mutual butt of the end face 33 of the bottom surface of joint seat 20 and housing 30, therefore increase the contact area that combines of

tool body

1 and 2 of battery components, thereby strengthen bond strength therebetween, make to be difficult for generation therebetween and to rock.

Four, when battery component 2 is combined on the tool body 1, the weight of battery component 2 combines rail 34 by two engagement grooves 221 and bears with two, and needn't be by two locking parts 42 and two blocks, 23 burdens of the locking effect that produces tool body 1 and battery component 2, therefore, the locking effect of 2 of tool body 1 and battery components is more firm.

Five, battery component 2 is broken away from from tool body 1, the user must push the press section 41 of two locking parts 40 simultaneously and could realize, so just can avoid the user to cause battery component 2 to break away from tool bodies 1 because of one of them of false touch two locking parts 40 in the process of using electric tool A.
