Abstract

The utility model relates to a hammer and belongs to the technical field of manual tools. The hammer comprises a hammer head and a hammer handle. An insertion hole penetrating up and down is disposed inside the hammer head. The top end of the hammer handle is inserted into the insertion hole. The hammer also comprises an iron wedge. The iron wedge is inlaid into the hammer handle from the top end of the hammer handle. The iron wedge includes a middle body which, as a whole, is shape like a trapezoid that is of a plate-shaped body structure, wherein the plate-shaped body structure has a wide and thick upper portion, and has a narrow and thin lower portion. Each of the left side edge and the right side edge of the iron wedge is zigzag. Two expansion bodies that are shaped like rectangular pyramid structures are arranged on each of two surfaces of the middle body. The two expansion bodies on the same side surface are symmetrical. An outer side surface of each expansion body is provided with a zigzag jamming stand. The iron wedge with a special structure is inlaid into the top end of the hammer handle to enable tighter and firmer connection between the hammer handle and the hammer head. Therefore, the hammer is enhanced in stability and thus is improved in safety performance.

Description

A kind of hammer

Technical field

The utility model relates to a kind of hammer, belongs to hand-operated tools technical field.

Background technology

Hammer is one of hand-operated tools conventional in people's daily life, and it is generally made up of tup and hammer handle, is provided with the jack of up/down perforation in described tup, and the top of hammer handle is plugged in described jack.The defect that traditional hammer exists is: tup is insecure with being connected of hammer handle, easily loosening, so that tup can be easy to split away off from hammer handle, and it is inconvenient, careless slightly to use, and also can damage the person.In prior art, be generally to adopt iron plate to add the fastening hammer handle of mode and the tup of screw, that is: cover the jack top at tup with iron plate, then screw is run through to iron plate and screw in hammer handle.But of long duration, screw occurs after loosening or fracture, and hammer handle is still easy to become flexible.

Utility model content

The purpose of this utility model is, the hammer that a kind of tup and hammer handle are connected firmly, security performance is high is provided, to solve the problems of the technologies described above.

For addressing the above problem, the technical scheme that the utility model adopts is:

A kind of hammer, comprises tup and wooden hammer handle, is provided with the jack of up/down perforation in described tup, and the top of hammer handle is plugged in described jack, it is characterized in that: described hammer also comprises that an iron carves, and described iron is carved from the top of hammer handle and is bumped in hammer handle; Described iron is carved and is comprised intermediate, trapezoidal, wide at the top and narrow at the bottom, upper thick and lower thin plate body structure that described intermediate is that entirety is, and its two sides in left and right are zigzag; On two surfaces of described intermediate, be respectively equipped with the expander of two rectangular pyramid structures, two expanders on same side are symmetrical arranged; The lateral surface of described expander is provided with jagged Ka Tai.

Beneficial effect: compared with prior art, be bumped into the iron with special construction and carve in hammer handle of the present utility model top, the expansion of carving by iron makes being connected more closely between hammer handle and tup, firmly, and steadiness strengthens, thereby has improved security performance.And iron is carved the zigzag Ka Tai on broached-tooth design and the expander lateral surface of intermediate dual-side, can guarantee that iron is carved loosening phenomenon can not occur in hammer handle.

Fig. 3 is the structural representation that described in the utility model, iron is carved.

Detailed description of the invention

Below in conjunction with detailed description of the invention and accompanying drawing, the utility model is further described.

As shown in Figure 1 and Figure 2, hammer described in the utility model, comprises that tup 1, wooden hammer handle 2 and iron carves 3.In described tup 1, be provided with the jack of up/down perforation, the top of hammer handle 2 is plugged in described jack, and described iron is carved 3 and is bumped in hammer handle from the top of hammer handle 2.

As shown in Figure 3, described iron is carved 3 and is comprised intermediate 31, and described intermediate 31 is trapezoidal for entirety, wide at the top and narrow at the bottom, upper thick and lower thin plate body structure, and its two sides in left and right are zigzag; On two surfaces of described intermediate 31, be respectively equipped with the expander 32 of two rectangular pyramid structures, two expanders 32 on same side are symmetrical arranged; The lateral surface of described expander 32 is provided with jagged Ka Tai.Described intermediate 31 and four expanders 32 are the one-time formed integral structure of mould.
