Description

Multipurpose hammer head and hand tool comprising same

Technical Field

The utility model relates to a hand tool, concretely relates to multipurpose tup and hand tool including this multipurpose tup.

Background

The prior hand hammer generally comprises a hammer head and a hammer handle connected with the hammer head. The hammer head has single purpose, and the use occasion is limited.

There is a need in the art for a hand tool that: the same hand tool can be used in different occasions, thereby reducing the number of tools to be carried and being more convenient to use.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides a multipurpose tup and hand tool including this multipurpose tup. The multipurpose hammer head is different from the existing common hammer head, and different striking parts are arranged at two ends of the hammer body so as to be used in different occasions or purposes. The utility model also provides a hand tool of including above-mentioned multipurpose tup, this hand tool mould the mode through the package with instrument handle (hammer handle) and above-mentioned multipurpose tup integrated into one piece, the wholeness is better, uses safe and reliable more.

First, the present invention provides a multipurpose hammer head, which includes a hammer body and a striking part coupled to the hammer body, wherein the striking part includes a first striking part coupled to the hammer body at one end of the hammer body, and a second striking part coupled to the hammer body at the other end of the hammer body, and the second striking part has a structure different from that of the first striking part; one of the first striking part and the second striking part is provided with a three-dimensional structure, the three-dimensional structure comprises cone convex parts and concave parts which are alternately arranged, and the cone convex parts are combined at one position to serve as an acting point.

In the present invention, the cone recess means a recess portion from the outer surface of the cone to the inside of the cone; by cone protrusion is meant the remaining part of the cone except for the cone recess.

In one embodiment, the number of the pyramidal projections is four, and the number of the pyramidal depressions is also four.

Further, the cone boss is formed by forging a hard material. The conical bulge formed by forging the hard material can ensure that the hammer head can be used for easily cutting into concrete in the striking process, thereby achieving the purpose of crushing harder materials such as concrete and the like.

In one embodiment, an outer dimension of the hammer body is smaller than outer dimensions of the first striking part and the second striking part.

Preferably, a cone groove is arranged on the hammer body.

The invention also provides a hand tool which comprises a tool head and a tool handle and is characterized in that the tool head is the multi-purpose hammer head described above, and a hammer body of the multi-purpose hammer head is integrated with the tool handle through plastic coating.

Drawings

fig. 2 is a perspective view of a hand tool including the multi-purpose hammer head of fig. 1 according to the present invention.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings. It is to be understood that the specific embodiments of the invention described in the attached drawings are for purposes of illustration only and are not to be construed as critical, if any, dimensions and proportions. Accordingly, the drawings in the present application should not be construed as limiting the invention in any way.

It is to be understood that the matter set forth in the accompanying drawings is illustrative only and should not be construed as limiting the invention in any way.

Fig. 1 is a schematic perspective view of the multipurpose hammer head of the present invention. As shown in fig. 1, a multi-purpose hammer head 100 of the present invention includes a hammer body 20, a first striking part 30 coupled to the hammer body 20 at one end of the hammer body 20, and a second striking part 10 coupled to the hammer body 20 at the other end of the hammer body 20, wherein the first striking part 30 and the second striking part 10 have different structures. As shown in fig. 1, the first striking part 30 may be a common striking part, such as a plane striking surface, while the second striking part 10 has a three-dimensional structure with alternating cone protrusions 110 and cone depressions 120, and the cone protrusions 110 are combined at a point 1101 as a force application point. In fig. 1, four cone protrusions 110 and four cone depressions 120 are shown in an alternating manner, but the present invention is not limited thereto, and other numbers of cone protrusions and cone depressions may be used.

For example, as shown in fig. 1, the second striking part 10 may be used for striking a concrete material, and the cone protrusion 110 may be made of a hard material. The cone-shaped protrusion 110 made of hard material is combined with the top 1101, and serves as a main acting point of the second striking part 10 and the concrete material to be struck. Hard materials are well known to those skilled in the art and will not be described in detail herein.

As shown in fig. 1, the outer dimension of the hammer body 20 is smaller than the outer dimensions of the first and second

striking portions

30 and 10. In order to increase the bonding strength between the hammer head 100 and the hammer handle 200, it is preferable to provide a groove 210 on the hammer body 20, so that plastic is injected into the groove during plastic coating to play a role in reinforcement.

As shown in fig. 2, the multipurpose hammer head 100 may be combined with the hammer handle 200 by plastic coating to form a hand tool 1000. Although a specific hammer shank 200 is shown, the present application is not so limited. The utility model can also adopt other forms of hammer handles or tool handles to be combined with the multipurpose hammer head 100.

Based on the description of the preferred embodiments of the present invention, it should be clear that the invention as defined by the appended claims is not limited solely to the specific details set forth in the above description, but that many obvious modifications thereof, which do not depart from the spirit or scope of the invention, are equally possible to achieve the objects of the invention.
