Tapping wrench with LED lamp

Abstract

The invention discloses a tapping wrench with an LED lamp, which comprises a handle, a connecting rod and a collet. Both ends of the handle are provided with internal threaded holes with openings facing outwards. One or both ends of the handle can be passed through the internal thread. The hole is threadedly connected to the extended handle with the screw, and the connecting rod includes an outer connecting rod and an inner connecting rod that can be retracted in the outer connecting rod, and several pairs of first through holes are provided on the inner connecting rod and the outer connecting rod, and the The inner connecting rod and the outer connecting rod pass through the corresponding first through hole through the first screw and are fixedly connected by the first nut. The handle is also equipped with a power supply device, a power switch and a metal hose with a power cord inside. The other end of the metal hose is connected with an LED lamp, and the power supply device, the power switch and the LED lamp are electrically connected. The wrench can add a handle to the handle to increase the torque. It has an LED light to provide good light. It can also be installed with different types of tapping heads to meet different job requirements.

Description

technical field [0001] The invention relates to a processing tool, in particular to a tapping wrench with an LED lamp. Background technique [0002] At present, the commonly used tapping wrenches, including handles, connecting rods and collets, are difficult and laborious to drill because the handles are relatively short and the fastening materials are relatively hard. In addition, when the light in the working environment is not good and when nuts of different sizes need to be tightened, the tapping wrench with a non-replaceable chuck cannot meet people's needs. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a tapping wrench with LED lights. The wrench can add a handle on the handle to increase the torque. Different types of tapping heads are suitable for different job requirements. [0004] In order to achieve the above object, the present invention is achieved through the following tech...
