Abstract

The present invention relates to a hammer, comprising a hammer head and a handle permanently connected to the hammer head both of which are made of a titanium alloy material, wherein the grip portion of the handle is coated with an anti-slip sleeve which is disposed with first anti-slip lines on the surface and a recess at one end close to the hammer head, and the recess is disposed with second anti-slip lines on the surface which are finer and denser than the first anti-slip lines; in operation, users grip the handle, with their thumbs stretching and just pressing on the recess. The hammer not only has high rigidity with light weight, but also is easy to hold.

Description

A HAMMER
BACKGROUND OF THE INVENTION
[0001] Technical Field

[0002] The present invention relates to a hammer, belonging to the technical field of hand tools.

[0003] Description of Related Art

[0004] As a hand tool commonly used in daily life and work, a hammer is used for beating objects to move or deform them and most commonly used to beat nails, correct or beat objects open.
Comprising a hammer head and a handle, a hammer has different forms such as claw hammer, wedge hammer and round-head hammer according to the shape of the hammer head.
Usually, the hammer head and the handle are removable structure, with the hammer head made of a variety of steel materials, so there are at least two shortcomings: 1) the hammer head is no longer firmly fixed to the handle and comes off easily after use for a long period;
2) the steel hammer head is relatively heavy.
BRIEF SUMMARY OF THE INVENTION

[0005] The aim of the present invention is to overcome the defects of the prior art mentioned above by providing a hammer which is light, highly rigid and easy to hold.

[0006] In order to solve the above-mentioned technical problems, the present invention provides a technical solution as below: a hammer, comprising a hammer head and a handle fixedly connected to the hammer head both of which are made of a titanium alloy material, wherein the grip portion of the handle is coated with an anti-slip sleeve which is disposed with first anti-slip lines on the surface and a recess at one end close to the hammer head, and the recess is disposed with second anti-slip lines on the surface which are finer and denser than the first anti-slip lines; in operation, users grip the handle, with their thumbs stretching and just pressing on the recess.

[0007] In the invention, the anti-slip sleeve is made of silicon rubber or soft plastics.

[0008] The beneficial effects of the present invention are as below: 1) the hammer head is made of a titanium alloy material which ensures its rigidity while reducing the weight of the hammer, making it light and easy to carry; besides, it also has a plurality of features such as high strength and good corrosion and heat resistance thanks to the property of the titanium alloy, so that it can be used in complex environments. 2) The anti-slip sleeve is disposed with a recess which is disposed with second anti-slip lines; when users grip the handle, their thumbs stretch and just press on the recess, so that they are able to apply their full strength with their thumbs pressing the handle, thus preventing the hand from slipping when users swing the handle.

[0009] On the premise of ensuring the rigidity of the hammer, the above-mentioned technical solution can be improved in the aspects as below in order to further reduce the weight of the hammer:
1) the handle is disposed with several holes which are located between the anti-slip sleeve and the hammer head. 2) The cross section of the part of the handle between the anti-slip sleeve and the hammer head is H-shaped.

[0010] In order to ensure the connection strength between the anti-slip sleeve and the handle, the above-mentioned technical solution can be improved in the aspects as below: 1) the grip portion of the handle is disposed with several barbs so that the handle does not loosen and come off easily once the handle is inserted into the anti-slip sleeve. 2) The anti-slip sleeve is disposed with interior-convex lines on the internal surface and a through-air passage formed between the lines and the handle surface extends to the outside of the anti-slip sleeve, so that when the handle is inserted into the anti-slip sleeve in installation, vacuum cannot be formed between the internal surface of the anti-slip sleeve and the surface of the handle, which prevents great resistance and improves convenience of installation; when users grip the anti-slip sleeve of an assembled hammer, the lines and the handle surface will be closely attached under the pressure applied by users on the anti-slip sleeve, thus achieving an anti-slip effect.

[0011] Preferably, the first anti-slip lines are distributed in a V, Y, diamond, slanted, parallel, nine square shape or other shapes.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Embodiments

[0017] As shown in FIG. 1 and FIG. 2, a hammer of the present invention, comprising a hammer head 1 and a handle 2 fixedly connected to the hammer head 1 both of which are made of a titanium alloy material, wherein the grip portion of the handle 2 is coated with an anti-slip sleeve 3, and the grip portion of the handle 2 and the anti-slip sleeve 3 are fixed via screws 8 or bolts. The anti-slip sleeve 3 is made of silicon rubber or soft plastics.

[0018] The anti-slip sleeve 3 is disposed with first anti-slip lines 4 on the surface and a recess at one end close to the hammer head 1, and the recess 5 is disposed with second anti-slip lines on the surface which are finer and denser than the first anti-slip lines 4; in operation, the users grip the handle 2, with their thumbs stretching and just pressing on the recess 5. The first anti-slip lines 4 are distributed in a V, Y, diamond, slanted, parallel, nine-square shape or other shapes.
The embodiment can also be improved in the aspects as below:

[0019] 1) the handle 2 is disposed with several holes 6 which are located between the anti-slip sleeve 3 and the hammer head I.

[0020] 2) the cross section of the part of the handle 2 between the anti-slip sleeve 3 and the hammer head 1 is H-shaped.

[0021] 3) the grip portion of the handle 2 is disposed with several barbs 7.

[0022] 4) the anti-slip sleeve 3 is disposed with interior-convex lines on the internal surface and a through-air passage formed between the lines and the handle 2 surface extends to the outside of the anti-slip sleeve.

[0023] The above-mentioned embodiment is not intended to limit the present invention, and other embodiments of the present invention can also be implemented in addition to the above embodiment. Any technical solutions provided from equivalent substitutions or changes are all included in the protection scope of the present invention.
