Description

Hammer grip

The present invention relates to a grip structure, and more particularly to a hammer grip applied to a construction site.

According to the hammer, the hammer is a widely used hand tool, especially in the fields of machinery, construction and woodworking. Most of the operators in these fields must strike the object repeatedly with a hammer; if the hammer is removed from the hand during use, it will cause damage to the person or the item, so avoid the hammer from slipping during use. Important safety requirements.

Therefore, a structure of a hammer is known, please refer to the figures 7 and 8, the anti-slip design is attached to the grip position of the hammer 20 relative to the grip 21, and a soft or plastic grip 22 is fixed to the grip 22 The grip 21 is used to increase the friction of the hand, and a gap between the grip 22 and the grip 21 can also provide a button press for the thumb to reach the limit limit to avoid the hammer slip. Disappearing; however, it is not difficult to find out the shortcomings of the above-mentioned conventional structure. The main reasons are as follows: Since the conventional gripper 22 is made of a soft or plastic material, plus the user. The palm of the hand is covered by cotton gloves, which not only makes the hammer drop imperfect, but also lacks the feel of holding the limit. On the other hand, because the texture of the grip 22 is soft and versatile, when the thumb is pressed At the same time, it is also easy to squeeze and deform due to the force, and thus can not effectively provide the stop limit effect, the actual lack of anti-slip off, the effect of the out, not practical.

Furthermore, the hammer applied to the construction site can be used as a tapping function. Bending metal rods such as steel bars and screws; therefore, another hammer structure on the market, please refer to FIG. 9 together, which includes a hammer body 30 having a grip The handle 31 and a tapping portion 32 are a metal tube body, and a socket 311 is formed at the end, and a stopper ring 33 is sleeved on the end of the handle 31 and connected by welding. The utility model is fixed, so that the hammer 30 can not only use the tapping portion 32 to achieve the tapping function, but also can be put on the steel bar through the metal tubular handle 31 through the socket 311, thereby pressing and bending the reinforcing bar; however, the detailed view The above-mentioned conventional structure is not difficult to find its shortcomings, and the main reason is as follows: although the grip 31 can be put on the steel bar through the socket 311 and flexed, but the thin tube material is still not effective. It is subjected to the reaction force of the solid steel bar and has deformation. Therefore, a stopper ring 33 is welded to the end of the grip 31 to reinforce the end strength of the grip 31, but also the connection between the grip 31 and the stop ring 33. The strength of the structure is reduced due to the welding process, so that the handle 31 wears the steel bar and applies force When off, it can not effectively withstand the welding force thereof, thereby generating the event of breakage (see also shown in FIG. 10), significantly reduce the life of persons; In addition, when the hammer body 30 is not in use, it can be engaged with the buckle at the waist. When the user kneels down and the handle 10 is naturally placed and adjacent to the ground, the handle 31 is made due to the sleeve of the stop ring 33. The end forms a convex-shaped hook, which makes the end of the handle 30 easy to hook to the wire, waste bag or rope body at the site (as shown in Figure 11), which limits the user's action or is frightened and has a center of gravity. Stable situation arises, increases the risk of work, and lacks the safety of structural use.

In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical.

The technical problem to be solved by the present invention is to provide a hammer grip for the above-mentioned drawbacks existing in the prior art.

A hammer grip comprising a handle, the handle is a hollow metal tube body, and a metal covering sleeve is provided on the handle from the bottom to the top, the sleeve bottom and the grip The handle is flush, and the length of the sleeve is at least one-half of the sleeve to the handle, and the top end of the sleeve is formed with the first surface of the handle surface. Forms a hammer grip.

Compared with the effect of the prior art: the grip sleeve has a sleeve, and the handle and the sleeve are made of a rigid metal material, which not only greatly increases the structural strength of the handle, but also prolongs the life of the structure. It also forms a stepped insert with obvious drop, which increases the feel of the thumb pressing and snapping, and prevents the user from pulling out the hammer during the hammering process, thereby improving the safety and practicability of the hammer.
