The above-mentioned scheme solves the technical problem that the striking area of the striking part 101 is fixed, which leads to the operator's easy hammer injury to the hand when hammering.
[0025] According to this specific embodiment, the outer side of the striking part 101 has an annular groove 103, the inner bottom of the annular groove 103 has a plurality of threaded grooves 104, one end of the connecting part 102 is provided with a step 105 and a mounting part 106, the striking part 101 is fixedly connected to the connecting part 102 and is located at the other end of the connecting part 102, by abutting the mounting part 106 in the bushing, the bushing is clamped on the outer side of the mounting part 106, thereby determining the disengagement direction of the bushing to avoid displacement, and then hammering the striking part 101 to make the connecting part 102 abut against the bushing and drive the bushing to disengage from the installation position to complete the disassembly.
[0026] Among them, multiple extension mechanisms are respectively arranged around the annular groove 103, a limiting plate 109 is arranged on the adjusting screw 107, a knob 110 is arranged at one end of the adjusting screw 107, a limiting groove 111 is provided in the extending portion 108, the adjusting screw 107 is rotatably connected with the extending portion 108 and is located in the extending portion 108, and the limiting plate 109 is located in the limiting groove 111, the adjusting screw 107 is also threadedly connected with the striking portion 101 and is located in the thread groove 104, the extending portion 108 is slidably connected with the striking portion 101 and is located in the annular groove 103, and by arranging multiple extension mechanisms, the striking area of the striking portion 101 is increased, thereby preventing the operator from causing hammer injuries to the hands when hammering, and the design can also facilitate the storage of the extension portion 108 so as not to affect subsequent carrying.
