Shortcoming at above-mentioned prior art exists the utility model proposes a kind of electronic hammer with nail pulling function.
In order to reach above purpose, the technical solution of the utility model is: a kind of electronic hammer comprises: casing, have grip part and head, and be mounted with nail hitting unit on the described head; Be contained in motor in the casing, by motor-driven transmission mechanism and impact assembly, the impact part of described impact assembly is periodically impacted impacting on the axle at described nail hitting unit; Described grip part has first longitudinal axis, and described nail hitting unit has second longitudinal axis, and described first longitudinal axis is vertical in fact with described second longitudinal axis; Also comprise nail extractor, described nail extractor comprises nail pulling portion and fixed part, be provided with between described nail pulling portion and the described casing can the ccontaining head of a nail the space.
Further, described nail extractor is arranged on described casing head.
Further, described nail pulling portion is provided with V-shaped part.
Further, described V-shaped part is towards the direction of described nail hitting unit.
Further, described nail extractor also comprises fixed part, and described fixed part has the bigger size than described nail pulling portion.
Further, the material of described nail extractor is different from the material of described casing.
Further, described nail extractor adopts metal material.
By adopting the accessible useful technique effect of above technical scheme to be:
1) because, electronic hammer is the most general with the occasion that securing members such as nail combine operation, nail extractor is attached on the electronic hammer can brings a lot of facilities undoubtedly, particularly deflected to extract the time when nail, directly utilize on the electronic hammer nail extractor to extract and need not many expenses twists and turns again and the time goes for the apparatus of seeking new nail pulling.
2), nail extractor is arranged on the casing head, and V-shaped part is towards the direction of nail hitting unit, and when being used to pull out a nail, the handle of nail is held in the V-shaped part, and grab handle is as the lever of exerting oneself, and the casing head is a fulcrum, can at an easy rate nail be extracted from the workpiece base material.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, stereogram for electronic hammer 1, electronic hammer 1 comprises casing 3, casing 3 is involuted by the two halves housing, its main part forms the grab handle 31 of a longitudinally, and the switch 6 that is used to control the motor start and stop in the casing 3 is installed on grab handle 31 positions, and the lower end of casing 3 is equipped with dc-battery bag 5, upper end head 32 places of casing 3 have rifle mouth portion 4, and rifle mouth portion 4 is equipped with the nail hitting unit 7 that is used to impact securing members such as nail.Grab handle 31 has first longitudinal axis Z 1, and it is vertical in fact with second longitudinal axis Z 2 that nail hitting unit 7 has second longitudinal axis Z, 2, the first longitudinal axis Z 1;
In the present embodiment, power brick 5 essentially coaxially is provided with the adjacent place of the housing of power brick 5 and casing 3, the outer surface smoother adjacency of the two with grab handle 31, at least a portion of power brick 5 is inserted in the casing 3, makes that the connection between power brick 5 and the casing 3 is more firm; In other embodiments, the also parallel or vertical setting of the longitudinal axis direction of grab handle 31 relatively of the power brick 5 of the electronic hammer of the utility model; Also be not limited to the power supply of dc-battery bag, can adopt Alternating Current Power Supply.
As shown in Figure 2, be electronic hammer 1 internal structure schematic diagram, be mounted with motor 2 in the casing 3, rotatablely moving of motor 2 changes percussion action to nail hitting unit 7 into by transmission mechanism, but nail hitting unit 7 comprise a linear reciprocating motion impact the axle 9, but transmission mechanism comprises the gear drive part 10 of vertical duction and is used to impact the impact assembly 8 that impacts axle 9 in the nail hitting unit 7, the impact part of impacting assembly 8 periodically impacts the quilt that impacts axle 9 continuously and impacts on the part, thereby the front end that impacts axle 9 periodically impacts on securing members such as nail continuously, and final the realization little by little knocked workpiece into to be processed with nail.
Can also be provided with nail extractor on the electronic hammer 1 of the present utility model, in conjunction with Fig. 3 and Fig. 4, the 30a of nail pulling portion that nail extractor 30 is used for nail pulling in the present embodiment gives prominence to outside casing 3, certainly, in other embodiments, the 30a of nail pulling portion of nail extractor also can with casing 3 concordant (not shown), be provided with the space of the ccontaining head of a nail between 30a of nail pulling portion and the casing 3.Have V-shaped part 301 on the nail extractor 30, preferably, nail extractor 30 is arranged on the casing head 32, V-shaped part 301 is towards the direction of nail hitting unit 7, be used to pull out a nail at 40 o'clock, the handle of nail 40 is held in the V-shaped part 301, and grab handle 31 is as the lever of exerting oneself, casing head 32 is a fulcrum, and nail 40 is extracted from workpiece base material 50.
Referring to Fig. 5 to Fig. 7, nail extractor 30 is fixed on the body of electronic hammer 1 by its fixed part 30b, the intensity that is connected and fixed for increase, preferred fixed part 30b has the bigger size of the relative nail pulling 30a of portion, as seen in Fig., fixed part 30b has the longer length than the 30a of nail pulling portion, in other embodiments, also fixed part 30b can be arranged to have than the 30a of nail pulling portion wideer width.Fixed part 30b can be fixed in the casing 3, also can be fixed on outside the casing 3, and perhaps, fixed part 30b and casing 3 are integrally formed, at this integrally formed part place inserts metal reinforced (not shown) is arranged.
