The handle 10 includes a coupling end coupled to the head 20 and a handle end gripped by an operator when working. The handle 10 has an overall long and thin rod shape like a general hammer, and may be formed of a generally widely used metal material or the like.

The handle 10 is preferably made of a hollow type for accommodating the driver striking unit 40 to be described later, and preferably has a circular cross-section on the inside, but is not necessarily limited thereto.

A housing 11 for accommodating the auxiliary striking unit 30 or the driver striking unit 40 is formed inside the handle end of the handle 10 . As shown in FIG. 1 , the receiving part 11 may be formed by processing the inside of the bag 10 to have a step.

The head 20 is coupled to the coupling end of the shaft 10 . To this end, the coupling portion 60 protrudes from the head 20 in the extension direction of the handle 10 . The coupling unit 60 may be integrally formed with the head 20 or may be coupled after being manufactured as a separate type. As shown in FIG. 1 , the coupling end of the coupling portion 60 and the shaft 10 may be screwed by a male screw 12 and a female screw 61 and fixed with a fixing pin 62 , and other techniques. It may be combined in various ways known in the art. Of course, it is also possible to use a fixing bolt instead of the fixing pin 62 .

A main striking portion 21 is formed on one side (left side of FIG. 1 ) of the head 20 . The main striking unit 10 serves as a striking function of a general hammer.

The other side (right side of FIG. 1) of the head 20 is open, and the receiving groove 22 is formed. The receiving groove has a depth that can accommodate the auxiliary striking unit 30 or the driver striking unit 40 . A female screw 23 for coupling with the auxiliary striking unit 30 or the driver striking unit 40 is formed on the inlet side of the receiving groove 22 .

The auxiliary striking unit 30 is detachably coupled to the receiving groove 22 of the head 20 .

In the central region of the auxiliary striking unit 30 , a stepped portion 34 caught on the inlet end of the receiving groove 22 of the head 20 is formed. The outer periphery of the stepped portion 34 is preferably hexagonal. Accordingly, the auxiliary striking portion 30 may be screwed into the receiving groove 22 of the head 20 using a tool such as a spanner. However, since the hexagonal outer periphery of the stepped portion 34 is only for a screw fastening tool, it may be formed in a different shape according to design or work needs.

It is preferable that a round (R) is formed at the hexagonal edge of the stepped portion (34), and it is more preferable that a curve connecting the six rounds (R) forms a circle. According to this configuration, when the auxiliary striking unit 30 is accommodated in the receiving unit 11 of the bag 10 , the stepped portion 34 can be smoothly inserted into the receiving unit 11 having a circular cross section. Here, when the stepped portion 34 has a different shape, it goes without saying that the receiving portion 11 may also have a different cross section.

On the left and right sides of the stepped portion 34 , male screws 33 screwed with the female screws 23 of the receiving grooves 22 are formed, respectively. Accordingly, the auxiliary striking unit 30 can be easily screwed into or separated from the receiving groove 22 of the head 10 , and the positions of the first auxiliary striking unit 31 and the second auxiliary striking unit 32 are can be easily replaced by replacing them with each other.

When the first auxiliary striking unit 31 is a flat striking unit, as shown in FIGS. 1 and 2 , a nail extraction groove 35 may be formed through the rear of the flat tip of the flat striking unit. This configuration borrows the technology disclosed in Prior Art 3 (Korea Utility Model Registration No. 20-0238335), and has the advantage of securing a nail pulling function while securing a flat striking unit.

According to the above-described configuration, it is possible to provide a multi-function hammer having at least three types of striking parts to be stored and replaced.

The driver striking unit 40 may be detachably coupled to the receiving groove 22 of the head 20 like the above-described auxiliary striking unit 30 . Since the auxiliary striking unit 30 and the driver striking unit 40 are coupled to the receiving groove 22 of the head 20 to be interchangeable with each other, any one of the two is coupled to the receiving groove 22 of the head 20 In this case, the other one may be stored in the receiving part 11 of the bag 10 .

1 and 3, on one side of the driver striking unit 40, a third auxiliary striking unit 41 having a general driver handle shape is formed in the body. The screwdriver handle-shaped body preferably has a hexagonal cross section for screwing to be described later.

In this embodiment, the third auxiliary striking unit 41 is preferably a round striking unit with a rounded tip, but is not necessarily limited thereto, and may be provided with a striking unit of another type according to design or work needs. .

A driver 42 may be coupled to the other side of the driver striking unit 40 . The driver 42 has cross-shaped and straight-shaped driver ends formed on one side and the other side, respectively, like a general driver, and can be interchangeably coupled to each other by changing directions.

A stepped portion 44 having the same configuration as that of the stepped portion 34 of the auxiliary striking portion 30 is formed in the central region of the driver striking unit 40, and the driver 42 side (left side of FIG. 3) has a head A female screw 23 of (20) and a male screw 43 for screwing are formed. The third auxiliary striking part 41, that is, the driver striking part 40 is only in one direction with the receiving groove 22, that is, the third auxiliary striking part ( This is because 41) is coupled only in the direction in which it protrudes to the outside.

According to this configuration, it is possible to provide a multifunctional hammer having at least four types of striking parts and drivers to be stored and replaced.

As shown in FIG. 3 , a handle groove 45 may be formed in a region adjacent to the third auxiliary striking portion 41 , that is, the round striking portion. The handle groove 45 is a configuration for use when a worker takes out the driver striking unit 40 by hand while the driver striking unit 40 is accommodated in the receiving unit 11 of the bag 10, Although shown in the form of a through hole, of course, it may be configured in the form of a concave groove.

In the present embodiment, the driver 42 is coupled to one side as an example of the driver striking unit 40, but according to design or work needs, other auxiliary striking units having a different type of striking unit instead of the driver 42 as needed. Of course, it can be provided instead of the driver striking portion 40, in this case, the external screws 43 are formed on both sides of the stepped portion 44, of course. In this case, it is possible to provide a multifunctional hammer equipped with at least five types of striking parts to be stored and replaced.

On the other hand, when hammering is performed in a state in which the driver striking unit 40 is accommodated in the receiving unit 11 of the shaft 10 , the driver 42 may be separated from the driver striking unit 40 to cause noise. In order to prevent this, according to this embodiment, as shown in FIG. 1 , the filling part 70 is filled on the coupling end side of the bag 10 and the driver striking part 40 is accommodated in the receiving part 11 . In this state, the tip of the driver 42 is configured to contact and support the filling part 70 .

The filling part 70 may also serve to reinforce the weight of the head 20, which is hollow due to the receiving groove 22 and the weight is reduced, and thus the hitting function may be lowered, together with the function of supporting the driver 42 in this way. . In particular, when considering such a weight reinforcement function, the front end of the filling part 70, that is, the coupling end of the bag 10, is made of a heavy material such as metal, and the opposite side is made of a light material such as wood. possible.

Even when the driver striking unit 40 is coupled to the receiving groove 22 of the head 20, as in the case where the driver striking unit 40 is accommodated in the receiving unit 11 of the handle 10, when hammering There is a fear that the driver 42 is separated from the driver striking unit 40 to cause noise. In order to prevent this, it is preferable that the receiving groove 22 of the head 20 has a depth sufficient to contact and support the tip of the driver 42 in a state in which the driver striking part 40 is coupled to the receiving groove 22 . . In this case, an appropriate buffer member may be attached to the inner end of the receiving groove 22 to buffer and support the tip of the driver 42 . Instead of this configuration, when hammering in a state in which the driver striking unit 40 is coupled to the receiving groove 22 of the head 20, it is of course possible to work without the driver 42.

The elastic striking unit 50 is used when striking a soft object or to reduce noise, and has a cap shape to cover the main striking unit 21 when in use, as shown by a two-dot chain line in FIG. 1 . When not in use, the elastic striking unit 50 covers the handle end of the handle 10 as shown by a solid line in FIG. 1 .

When the elastic striking unit 50 is coupled to the main striking unit 21 and used, the open end of the handle end of the handle 10 is opened so that the auxiliary striking unit 30 or the driver striking unit 40 accommodated therein is Since there is a risk of separation, in order to prevent this, the handle cap 80 is detachably coupled to the open end of the handle end of the handle 10 to support the third auxiliary striking unit 41 of the driver striking unit 40 . there is. A member (not shown) such as a ring for an operator to pull by hand may be formed on the sack cap 80 .

Although the present invention has been described in detail with reference to embodiments and the accompanying drawings in the above, the technical spirit of the present invention should be defined by the matters described in the claims, and within the scope not departing from the scope of the technical spirit of the present invention.
