Universal rotary spanner with angle positioning function

Abstract

The invention discloses a universal rotary spanner with angle positioning function, which comprises a grip, a driving head and a fastening device. The grip comprises a holding position and a clampingposition, wherein the clamping position comprises two clamping pins, the tail ends of the two clamping pins are clamping parts respectively, one clamping part comprises a hole and a positioning part,and the other clamping part is provided with a hole; one side of the driving head is extended with a shaft part and a positioning part, the other side of the driving head is extended with a shaft part, the two shaft parts pass through the two holes respectively, and the positioning part of the driving head corresponds to the positioning part of the clamping part of the grip and is selectively engaged; and the fastening device is arranged between the two clamping pins and controls the distance between the two clamping pins; and furthermore, the two clamping parts clamp the driving head, and thepositioning part of the driving head is positioned at the positioning parts of the clamping pins to generate positioning effect.

Description

technical field [0001] The invention relates to a universal rotary wrench, which refers to a wrench whose driving head can rotate relative to each other and be positioned at any position. Background technique [0002] Referring to U.S. Patent No. 7246544 "ROTARY WRENCH", a rotary wrench is disclosed, which includes a handle 20 and a drive head 30. One end of the handle 20 forms two lugs, and two lugs are respectively provided with a screw hole 211, 212. A threaded shaft 32, 33 protrudes from both sides of the driving head 30, and the threaded shafts 32, 33 of the driving head 30 are screwed into the screw holes 211, 212 of the handle 20, so as to prevent the driving head 30 from being separated from the handle 20. . [0003] However, the design of the above-mentioned patent can only produce positioning effect when the driving head is locked on the handle. When the operator rotates the driving head and the handle at an angle that does not have positioning, at this time, the ...

Problems solved by technology

[0003] However, the design of the above-mentioned patent can only produce positioning effect when the driving head is locked on the handle. When the operator rotates the driving head and the handle at an angle that does not have positioning, at this time, the handle and the driving head can be rotated arbitrarily. without targeting

[0004] The design of the above-mentioned patent achieves the combination of the handle and the drive head, but only when the handle and the drive head are relatively locked can it have a positioning effect, and there are deficiencies in the design and need to be improved.
