Embodiment Construction
[0013] Referring to the accompanying drawings, the friction type manual wrench includes a base 1, a rectangular steel sleeve 2 is arranged on the base 1, and a steel slide plate 3 is slidably fitted in the rectangular steel sleeve 2, and the same end of the steel slide plate 3 and the base 1 is respectively fixed. There are mutually corresponding jaw front ends 4 and jaw rear ends 5, and the jaw front ends 4 and jaw rear ends 5 are arranged vertically with the steel slide plate 3 and the base 1 respectively, and the rear ends of the steel slide plate 3 are hinged with a press plate 6, and the press plate 6 and the inner wall of the rear part of the base 1 respectively have corrugated upper protrusions 7 and lower protrusions 8 that match each other. The front end of the pressure plate 6 is provided with a pressure plate end 9, which is set on the steel slide plate by rotating the shaft. The rear end, the width of the end of the pressure plate is smaller than the pressure plate....

The invention discloses a friction type manual wrench. The manual wrench comprises a base, a rectangular steel sleeve is arranged on the base, a steel sliding plate is in sliding fit in the rectangular steel sleeve, a jaw front end and a jaw rear end which are corresponding are fixed at the same ends of the steel sliding sleeve and the base respectively and are perpendicular to the steel sliding plate and the base respectively, a pressing plate is hinged to the rear end of the steel sliding plate, and matched wavy upper protrusions and lower protrusions are arranged on the inner walls of the pressing plate and the inner wall of the rear portion of the base. According to the friction type manual wrench, the steel sliding plate is pushed or retracted according to the size of a nut to be rotated, the pressing plate is put down to enable the lower protrusions to contact with the upper protrusions, the rear end of the wrench is held with a hand, and accordingly, an object to be rotated can be fastened or loosened, and rotation requirements of various nuts are met.
Description
technical field [0001] The invention relates to a mechanical wrench, in particular to a friction type manual wrench. Background technique [0002] The mechanical wrench in the prior art has the following disadvantages: 1) When the wrench rotates the nut, the wrench and the nut slide against each other. 2) Traditional wrenches can only rotate nuts with a fixed diameter. 3) It takes cumbersome operations to achieve the distance between the jaws and the diameter of the object to be rotated. Contents of the invention [0003] The purpose of the present invention is to provide a friction type manual wrench, which pushes or retracts the steel slide plate according to the size of the nut to be rotated, and then puts down the pressure plate so that the lower protrusion contacts the upper protrusion, and the rear end of the wrench is held tightly by hand The object to be rotated can be tightened or loosened to meet the rotation requirements of various nuts.
