Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Example (b):

referring to fig. 1-2, the steel core handle vibration-proof hand hammer of the present embodiment comprises a hammer head 2 and a handle. The hammer head 2 is generally made of steel, and may be made of non-metal materials such as wood, rubber, etc. or other metal materials, and the size, shape and material of the hammer head are different according to the functions. As shown in fig. 2-4, a central through hole 21 is formed in the hammer head 2; the bottom of tup 2 is equipped with and is oval-shaped draw-in groove 22 No. one.

The handle comprises a hand grip 5, an elastomer 3 and a steel core 4.

As shown in fig. 5 and 6, the cross section of the top end of the elastic body 3 is an ellipse matched with the size and shape of the first slot 22, and the top end of the elastic body 3 is inserted into the first slot 22 at the bottom of the hammer head 2. The center of the elastic body 3 is provided with an upper perforation 31; the bottom of the elastic body 3 is provided with an oval second clamping groove 32; a communication hole 33 is arranged between the upper through hole 31 and the second card slot 32. The elastic body 3 is positioned between the hammer head 2 and the hand-held handle 5, is made of rubber and other synthetic materials to absorb the vibration of the hammer head 2, and meanwhile has proper bending strength, so that the hand hammer cannot be obviously deformed in the swinging process.

The handheld handle 5 is generally made of wood, the cross section of the top end of the handheld handle is an ellipse matched with the size and the shape of the second clamping groove 32, and the top end of the handheld handle 5 is inserted and assembled in the second clamping groove 32 at the bottom of the elastic body 3; as shown in fig. 7, a lower through hole 51 is formed in the center of the handle 5, and a tapered hole 52 communicating with the lower through hole is formed at the bottom end of the handle 5.

The bottom of the handle 5 is provided with an end cover 6, as shown in fig. 2 and 8, the whole end cover 6 is oval and matched with the bottom end of the handle 5, and the center of the end cover 6 is provided with an upward conical bulge which is inserted into the conical hole 52.

The steel core 4 is manufactured according to the standard of bicycle spokes, and the bottom end of the steel core is provided with a bottom seal head. The top end of the steel core 4 is provided with external threads, the external threads sequentially penetrate through the end cover 6, the taper hole 52, the lower through hole 51, the communicating hole 33 and the upper through hole 31 from bottom to top, and after the top end of the steel core is inserted into the central through hole 21, the steel core is locked and fixed through the nut 1, so that the hammer head 2, the elastic body 3, the handheld handle 5 and the end cover 6 are connected into a whole. Handle and the tup of hand hammer are connected, the screw-thread fastening through steel core 4 between 2, have changed the atress mode of handle, promptly: the bending stress of the handle in the traditional mortise and tenon structure is converted into the tensile stress of the steel core and the compressive stress of the handle, the mechanical properties of tensile strength of the steel core and compressive strength of the handle are fully exerted, the disadvantage of low bending strength of the handle is avoided, and the handle is prevented from being broken.

The nut 1 is of the same structure as a bicycle spoke nut, and a threaded hole 11 matched with the external thread at the top end of the steel core 4 is formed in the center of the nut. The steel core 4 is essentially a long and thin bolt, the tail part of the steel core is flat and long, and the steel core 4 is matched with the end cover 6, so that the steel core 4 can be prevented from rotating when a nut is screwed. Under the condition of manual use, the probability of breakage of the steel core is extremely low, and therefore, the hammer head cannot fall off.

It should be noted that, for claw hammer nail-pulling hammers, the handle does not include an elastic body, i.e. only the handle and the hammer head need to be held by hand to be assembled, and the steel core is adopted to penetrate and connect from the center into a whole.

The technical content which is not detailed in the present invention is the common general knowledge in the field.

The foregoing illustrates and describes the principles, principal features, and technical advantages of the present invention. It will be understood by those skilled in the art that the foregoing embodiments have been described only for the purpose of illustrating the principles of the invention, and that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the claims and their equivalents.
