Technical field

The utility model relates to a kind of electric tool, particularly relates to the electronic hammer that a kind of energy realization impacts securing members such as nails.

Background technology

Electronic hammer is a kind of hand-held tool commonly used, and it is of a great variety.According to power source, electronic hammer can be divided into pneumatic and electronic two big classes.Wherein, pneumatic electronic hammer must have compressed air source in addition, therefore uses limited.The basic structure of electronic hammer can reduce: the motor that is placed in the rifle body is connected with the nail hitting bar that is placed in rifle head place by rotation-rectilinear motion transmission mechanism, thereby can convert electrical energy into reciprocating mechanical energy under switch control.

Yet electronic hammer of the prior art does not have the function that is easy to carry about with one usually, particularly in the practical operation occasion, such as, when needing high-rise working, the operator wishes to vacate two hands climbings, can also carry electronic hammer simultaneously.

Summary of the invention

At the shortcoming that above-mentioned prior art exists, the utility model provides a kind of electronic hammer easy to carry.

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 work head, and the work head is equipped with nail hitting unit; Place motor in the casing, by motor-driven transmission mechanism and percussion mechanism; The impact part of percussion mechanism periodically impact nail hitting unit by impact part; Electronic hammer also is provided with hook, and described hook has the hook portion that protrudes at least outside the described casing when being used state.

Described hook is arranged on the work head zone.

Described hook is arranged on the end of grip part.

Also comprise the dc-battery bag, described dc-battery bag is provided with the end of grip part.

Described hook roughly is positioned on the position of centre of gravity of described electronic hammer.

Described hook is arranged on the described power brick.

Electronic hammer of the present utility model is provided with hook, and handled easily the person carry.

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, schematic diagram for electronic hammer 1 of the present utility model, 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.

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 (as shown in Figure 6) relatively of power brick 5.

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 transmission mechanism comprises the gear drive part 10 of vertical duction and is used to impact the impact assembly 8 of nail hitting unit 7, but nail hitting unit 7 comprise a linear reciprocating motion impact the axle 9, impact assembly 8 and comprise rotating shaft 11 and beater wheel 12 with identical rotation, rotating shaft 11 is supported in the casing head 32 by bearings at both ends, and by turning to the bevel gear driven rotary, beater wheel 12 roughly is the plate-like of hollow, and be sleeved on the rotating shaft 11 by its hollow space, beater wheel 12 is provided with at least one, preferably, its rotation is provided with two symmetrically by the outwards outstanding impact portion 121 of outer circumference surface relatively, drive in the process of beater wheel 12 rotations at rotating shaft 11, the impact portion 121 of beater wheel 12 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.

Also be provided with the hook 8 of suspension member effect on the electronic hammer 1 of the present utility model, referring to Fig. 1, Fig. 3 and Fig. 4, hook 8 is arranged on the casing 3, when actual needs, can hang on operator's the waistband, is easy to carry.Hook 8 has when it and is in the part that plays the hook effect that protrudes in when being used state outside the casing 3, this hook can be one to be different from the metalwork of case material, it can have the multiple position that is provided with on casing, when it is arranged on the two ends of casing, in the zone such as end that is arranged on casing grip part 31 or casing head 32, at this moment, the main body of hook is parallel with the longitudinally of the grip part 31 of casing 3, and whole electronic hammer firmly hangs under the gravity effect of himself; When hook 8 is arranged on the approximate mid-section position of electronic hammer 1, be preferably placed at the position at the center of gravity G place of electronic hammer, and, the main direction of hook 8 is vertical with the longitudinally of the grip part 31 of casing 3, at this moment, be in the body weight relative equilibrium of hook 8 both sides, hang firm.

As Fig. 5, shown in Figure 6, hook that can also be arranged on power brick that casing 3 is connected on, in addition, the grip part 31 of casing 3 also can be short and thick palm shape grip part 31 '.

The electronic hammer that the utility model disclosed is not limited to the structure of content described in the above embodiment and accompanying drawing representative; such as; this hook can also be arranged to be connected on the casing slidably; or casing is folding relatively; also can be when using the hook state; protrude in outside the casing; and when state is linked up with in non-use; hook is at least in part by in the indentation casing; hook can also be arranged to magnetic; in a word, on basis of the present utility model to the wherein shape of member and the conspicuous change that the position is done; substitute or revise, all within the claimed scope of the utility model.
