Telescopic screwdriver with movable screwdriver bit

Abstract

The invention relates to the field of hardware tools, in particular to a telescopic screwdriver with a movable screwdriver bit. The telescopic screwdriver comprises a screwdriver body which comprises a screwdriver handle, one end of the screwdriver handle is provided with a hollow master rod, and the inner wall of an inner cavity of the hollow master rod is provided with an internal thread. A slave rod is inserted in the hollow master rod by screwing, and the outer wall of the slave rod is provided with an external thread matched with the internal thread of the hollow master rod. A cross screwdriver bit is arranged at one end of the slave rod, and the movable screwdriver bit is hinged to the other end of the slave rod and fixed by a bolt. The screwdriver is provided with the telescopic rod with the movable screwdriver bit, and a trapezoidal flat-end hammer is arranged at the end of the screwdriver handle. Therefore, the telescopic screwdriver with the movable screwdriver bit is simple in structure, convenient to use and capable of quickly screwing and unscrewing screws with narrow break joints, and labor efficiency is improved while labor intensity is relieved.

【Technical field】 [0001] The invention relates to the field of hardware tools, in particular to a telescopic screwdriver with a movable cutter head. 【Background technique】 [0002] A screwdriver, commonly known as a screwdriver, is used as a hardware tool for screwing screws. It is composed of a handle and a knife rod with a knife head arranged at one end of the handle; The gap between the two component parts is relatively narrow. At this time, when the screws installed on the side wall of the component part need to be unscrewed, because the head of the traditional screwdriver is not bent to 90 degrees, only the parts next to the component part can be used. It is troublesome and inconvenient to remove first, and then unscrew the screws of the component parts, increase the work intensity, and is not conducive to the rapid repair of the machine, so as to ensure that the production can be resumed in the shortest time; , so there is also the problem that there is no way to unsc...

[0002] A screwdriver, commonly known as a screwdriver, is used as a hardware tool for screwing screws. It is composed of a handle and a knife rod with a knife head arranged at one end of the handle; The gap between the two component parts is relatively narrow. At this time, when the screws installed on the side wall of the component part need to be unscrewed, because the head of the traditional screwdriver is not bent to 90 degrees, only the parts next to the component part can be used. It is troublesome and inconvenient to remove first, and then unscrew the screws of the component parts, increase the work intensity, and is not conducive to the rapid repair of the machine, thereby ensuring the requirement of production recovery in the shortest time; in addition, because the length of the screwdriver blade is fixed , so there is also a problem that there is no way to unscrew the screws that are deeper in the above gap
