The latching portion 331 is mounted on the latching slot 131, and the cross section of the latching portion 331 and the opening of the latching slot 131 are the same polygon, so that the screwdriver bit 33 does not idle when used. The screw lock 332 is used to tighten or loosen the corresponding type of screw 6. The screw-locking portions 332 of the screwdriver bits 33 are in a one-piece type, a cross-type type, a meter-type type, or a polygonal type. It is to be noted that the bottom of the card slot 131 is further provided with a magnetic component 132. The screwdriver head 33 is made of a magnetic material. When the screwdriver bit 33 is mounted on the card slot 131, it will be The magnetic member 132 is magnetically attracted so that the screwdriver bit 33 is detachably attached to the latching groove 131 while preventing falling during use.

Referring to FIG. 1 to FIG. 6, the following is a description of the process of using the combination to push a nail 4 into a substrate 5 as an example to illustrate the use of the composite crucible. First, as shown in FIGS. 1 and 2, the metal boring tool 31a is selected from the tool set 3, and the connecting portion 311 is screwed into the screw hole 211 of the engaging end 21. Next, as shown in FIG. 4, the nail 4 is placed in the positioning groove 221, so that the top of the nail 4 is magnetically attracted to the magnetic slider 223, and then the combined cassette is moved to be adsorbed on the combined cassette. The nail 4 is aligned with the position on the substrate 5 to be nailed, at which time the elastic member 222 has not been compressed. Then, as shown in FIG. 5, the combination cymbal is slightly swung up and down, and the tip end of the nail 4 is positioned in the substrate 5 by the positioning end 22, and the magnetic member 222 is telescoped in the positioning groove 221 to make the magnetic The slider 223 is slidable back and forth in the positioning groove 221, and the tip end of the nail 4 is gradually tapped into the substrate 5 by the combination. Finally, as shown in FIG. 6, the tapping portion 312 of the metal boring tool 31a strikes the top end of the nail 4, and the combined cymbal 4 is greatly swung up and down, so that the entire nail 4 is driven into the substrate 5. . In this way, the user can use the hand to hold the nail 4 The nail 4 is nailed into the substrate 5 to prevent the metal hammer tool 31a from knocking on the user's hand and causing injury. It should be noted that when the composite cymbal is swung up and down, the gravity block 24 in the engaging body 2 will be driven back and forth between the engaging end 21 and the positioning end 22 when the gravity block 24 hits the positioning. The end 22 provides additional impact force to aggravate the force of the combination 槌 tapping the top end of the nail 4, making the process of nailing the nail 4 more efficient.

In addition, the magnetic slider 223 of the combination cassette can be used to collect the workpieces that can be magnetically attracted by the nails 4, the screws 6 and the like in actual use, so as to prevent the user's hands from being injured by touching the tips of the workpieces. At the same time, it can also increase work efficiency.

2 and 7, the use of the combination of the screws 6 into the substrate 5 is taken as an example to illustrate another method of using the composite crucible. First, referring to Fig. 2, a screwdriver bit 33 matching the screw 6 is selected from the tool set 3, and is attached to the latching groove 131 of the main rod 1. Next, as shown in FIG. 7, the user can hold the screw 6 on the substrate 5 with the hand to be screwed into the position to be screwed, and the other hand to stand up the assembly and align the screw with the screw portion 332. The screwing process of the screw 6 on the base plate 5 can be completed by applying a force to the engaging body 2 to rotate the main rod body 1 about its own axis.

Hereinafter, a process of using the combination 槌 to pull out a nail 4 from the substrate 5 will be described with reference to FIGS. 1 and 8. First, referring to FIG. 1, the nail removing tool 32 is selected from the tool set 3, and the connecting portion 321 is screwed into the engaging end 21 Inside the screw hole 211. Next, as shown in FIG. 8 , the assembly is inverted, and the nail 4 is clamped by the nail removing portion 322 of the nail removing tool 32 , and the connecting body 2 is used as a fulcrum against the substrate 5 to pull the main body. The rod body 1 can be pulled out.

In summary, the combination of the present invention enables the combined hammer of the present invention to have the functions of a hoe, a nail puller, a screwdriver and the like by means of the replaceable tool set 3, thereby achieving the advantages of convenient carrying and space saving. In addition, the design of the elastic member 222 and the magnetic slider 223 allows the user to smoothly push the nail 4 into the substrate 5 without holding the nail 4 by hand, so as to prevent the combination from knocking on the user's hand. The department caused injuries. In addition, when the combined cymbal is swung up and down, the gravity block 24 in the engaging body 2 is driven to collide back and forth between the engaging end 21 and the positioning end 22, and the combination 加 is tapped on the nail 4 The force of the tip makes the process of nailing the nail 4 more efficient, so it is indeed possible to achieve the object of the present invention.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
