換しなければならない。 Conventional electric hammers have a tool holding function that uses a groove in the tool and a U-shaped hole in the tool holding part in the main body to prevent the tool from falling out of the machine and to remove it from the tool and workpiece. ing. The retainer pin that connects the U-shaped hole tool holder (hereinafter referred to as retainer) to the machine body is assembled by press-fitting and caulking into the front cover. However, when disassembling and replacing the retainer due to its lifespan, the retainer pin cannot be disassembled due to its structure, and the front cover, retainer, and retainer pin must be replaced in an assembled state.
本考案の目的は、上記した従来技術の欠点をな

保守が簡便にできる。 FIG. 1 shows a tool holder of an electric hammer that applies an impact to the tip tool 1 and breaks the workpiece. A retainer 2 that holds a tool is press-fitted to a front cover 3 by a retainer pin 5, and the retainer pin has a screw hole 6. In the above configuration, when disassembling the retainer pin, tighten the screw in the screw hole and pull it out with a vise. Also, use a jig and pull out with a hand press. As described above, a retainer pin that can be disassembled is provided, and maintenance of the tool holding part can be easily performed.
変形応用例を第２図に示す。 An example of a modified application is shown in Figure 2.
リテーナピン１０に貫通穴１１を付加したもの

ナピン５の抜いた穴より芯金を通しリテーナ１０
をはずすことができる。 A through hole 11 is added to the retainer pin 10. When disassembling the retainer pin 10, pass the core metal through the through hole 11 and remove the retainer pin 5 using a hand press or the like.
can be removed.
本考案によれば、リテーナピンにネジ穴若しく
は貫通穴を配設したので、リテーナピンの分解を
可能にすることができる。 According to the present invention, since the retainer pin is provided with a screw hole or a through hole, the retainer pin can be disassembled.
