Embodiment Construction

[0010] Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is further described:

[0011] like figure 1 As shown, a telescopic wrench includes a trigger 1 and driving parts at both ends of the trigger 1, and the two ends of the trigger 1 are extended with a first inclined part 2 and a second inclined part 3, and the first inclined part 2 and the second inclined part The bending direction of part 3 is opposite, the first inclined part 2 is extended with the first driving part 4, and the second inclined part 3 is extended with the second driving part 5; . The first driving part 2 is a quincunx part, and the second driving part 5 is an opening part. The quincunx portion is a circular ring with adjacent ribs arranged at intervals. The opening part includes a large block and a small block, the large block and the small block form a U-shaped mouth that gradually opens from the inside to the outside, and the direction of th...

Abstract

The invention discloses a telescopic spanner and belongs to the hand-operated tool field. The telescopic spanner comprises a trigger piece and drive parts arranged at the two ends of the trigger piece, wherein a first inclined part and a second inclined part are further arranged at the two ends of the trigger piece, the first inclined part and the second inclined part are opposite in bending direction, and the first drive part extends from the first inclined part, while the second drive part extends from the second inclined part; the trigger piece is a telescopic rod which is located on the middle part of the trigger piece. The telescopic spanner of the scheme is capable of reducing unnecessary interference in work and improving the working efficiency.

Description

technical field [0001] The invention relates to a hand tool, in particular to a wrench. Background technique [0002] A wrench is a common hand tool. When in use, force is applied to the hand-held part, and the screw is rotated by using the principle of leverage to achieve the effect of locking or dismounting the parts. The wrench in the prior art is linear, and when there are other parts around the target part, turning the wrench will cause obstacles and affect work efficiency. Contents of the invention [0003] The technical problems to be solved by the present invention include: when the operator uses the wrench in the prior art, there are other parts around the target part to be worked, which will hinder the movement of the trigger when turning the wrench, which will interfere with the work. [0004] In order to solve the above-mentioned technical problems, the present invention provides a telescopic wrench, which includes a trigger and driving parts at both ends of t...
