Description

Electric hammer

Technical field

The utility model is related to a kind of electric hammer.

Background technology

Electric hammer is one kind of electric tool, is mainly used to drill on concrete, floor, brick wall and stone material.The hand of electric hammer Handle structure is generally made up of handle main body and handle bonnet, is connected between the two by multiple fasteners, and dismounting is inconvenient, maintenance Inconvenience, profile is also unsightly.

Accordingly, it is desirable to provide a kind of new technical scheme solves the above problems.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of electric hammer.

In order to solve the above technical problems, the electric hammer that the utility model is provided, it includes gear-box, is connected with gear-box front end Quick chuck, be connected with gear box back handle arrangement, be installed on the anterior auxiliary-handle of gear-box and positioned at gear-box The motor casing of lower rear, the gear-box rear portion underrun middle cover is connected with motor casing, and the handle arrangement includes hand Handle main body and handle bonnet, by a screw connection between the handle main body and handle bonnet, the motor casing rear end with Handle main body bottom is connected.

Further, the gear box back passes through concaveconvex structure clamping with handle main body upper end.

Further, the concaveconvex structure is included positioned at the first groove of gear box back and the first convex surface and positioned at handle Second convex surface of main body upper end and the second groove, first convex surface and the second groove are connected, second convex surface and the One groove is connected.

Electric hammer of the present utility model, handle arrangement simple structure, only one screw of need just can be by after handle main body and handle Lid is opened, easy to maintenance, good appearance, and gear box back is with handle main body upper end by concaveconvex structure clamping, and fixing is more stable, Without fastener connection.

Embodiment

In order to deepen to understand of the present utility model, further is made to the utility model below in conjunction with embodiment and accompanying drawing It is described in detail, the embodiment is only used for explaining the utility model, does not constitute the restriction to protection domain of the present utility model.

As shown in Fig. 1 and Fig. 1 a, electric hammer of the present utility model, it include gear-box 1, be connected with the front end of gear-box 1 it is fast Fast chuck 2, the handle arrangement being connected with the rear end of gear-box 1, it is installed on the anterior auxiliary-handle 3 of gear-box 1 and positioned at gear-box 1 The motor casing 4 of lower rear, the rear portion underrun middle cover 5 of gear-box 1 is connected with motor casing 4, and handle arrangement includes handle master Body 7 and handle bonnet 8, are connected between handle main body 7 and handle bonnet 8 by a screw 9, the rear end of motor casing 4 and handle master The bottom of body 7 is connected.Handle main body 7 and the need one of handle bonnet 8 screw can just be connected, air attractive in appearance, and convenient disassembly opens spiral shell Silk is with regard to that can be repaired.

Shown in Fig. 2, the rear end of gear-box 1 passes through concaveconvex structure clamping with the upper end of handle main body 7.Gear-box 1 and handle main body 7 Between fix it is more stable, without fastener connection.

Shown in Fig. 3, wherein, concaveconvex structure includes the first groove 11 and the first convex surface 12 and position positioned at the rear end of gear-box 1 The second convex surface 71 and the second groove 72 in the upper end of handle main body 7, the first convex surface 12 are connected with the second groove 72, and second is convex The groove 72 of face 71 and first is connected.The embedded mode of concaveconvex structure so that the rear end of gear-box 1 and the upper end card of handle main body 7 Connect more firmly, while dismounting is also convenient for.

Electric hammer of the present utility model, handle arrangement simple structure, only one screw of need just can be by after handle main body 7 and handle Lid 8 is opened, easy to maintenance, good appearance, and the rear end of gear-box 1, by concaveconvex structure clamping, is fixed more steady with the upper end of handle main body 7 It is fixed, without fastener connection.
