Abstract

The invention relates to a semi-automatic multifunctional fast-screwing spanner. The semi-automatic multifunctional fast-screwing spanner comprises an upper spanner lip handle with an upper spanner lip and a lower spanner lip handle with a lower spanner lip. The lower spanner lip handle is further provided with a sleeving connection part. The lower spanner lip handle is matched with the upper spanner lip handle in a sleeving connection mode through the sleeving connection part, and a spanner opening is formed between the upper spanner lip and the lower spanner lip after sleeving connection matching is completed. A gap is reserved in the sleeving connection matching position between the inner surface of the sleeving connection part and the outer surface of the upper spanner lip handle and further serves as the rotating allowance allowing the lower spanner lip handle to rotate around the upper spanner lip handle through a rotating shaft. The size of the spanner opening located between the upper spanner lip and the lower spanner lip is changed along with the relative rotation position of the lower spanner lip handle and the upper spanner lip handle, so that a movable spanner opening is formed. According to the semi-automatic multifunctional fast-screwing spanner, an adjustable spanner and pliers are ingeniously combined, the spanner functions are achieved and meanwhile the openingand closing characteristic of the pliers can fused; and compared with an original monkey spanner, the semi-automatic multifunctional fast-screwing spanner is made faster. Meanwhile, the functions ofthe pliers and pincers can be achieved, and the spanner also can be used as pipe tongs.

Description

technical field

[0001] The invention relates to the technical field of hand tools, in particular to a semi-automatic multifunctional quick-twist wrench. Background technique

[0002] Adjustable wrench, also called adjustable wrench, is a tool for tightening or loosening angled screws or nuts. When turning a small nut, the lip of the wrench is on the top and the lip of the wrench is on the bottom. Because of the need to continuously rotate the worm wheel, adjust the wrench Therefore, the hand should be held close to the lip of the wrench, and the worm gear should be adjusted with the thumb to suit the size of the nut. Ordinary adjustable wrench is relatively slow in adjustment, and the worm gear is often stuck, and the screwing efficiency is low. Contents of the invention

[0003] The purpose of the present invention is to overcome the problems existing in the prior art and provide a semi-automatic multifunctional quick-twist wrench.

[0004] In order to achieve the above-...
