Abstract
The utility model relates to an adjustable bicycle spanner belonging to a hand tool. An adjustable component of a jaw is provided with an inner hexagonal bore; the fixing component of the jaw is provided with a gap of 120 DEG. Thus, people can adjust the size standard of the jaw by turning a knob to fit for screws with different standards. The utility model has the advantages of firm clamping and difficult falling from screws.
Description
The utility model belongs to hand tools.
At present, the jaw of commercially available monkey wrench is two parallel planes adjusting size, this monkey wrench, easy slippage during the clamping screw.
The purpose of this utility model is exactly to solve above-mentioned deficiency, and a kind of monkey wrench that provides.
Realize that solution of the present utility model is that this monkey wrench is made up of jaw movable part (1), knob (2), minor axis (3), jaw fixture (4), its special feature is that the associated jaw portion of jaw movable part (1) is an interior hexagonal hole, and jaw fixture (4) the termination portion in the jaw movable part (1) of being enclosed within is one 120 ° a breach.
Advantage of the present utility model is exactly that the clamping screw is more firm, generally is not easy slippage.
Accompanying drawing is a schematic diagram of the present utility model.
The contrast accompanying drawing is described in further details the utility model below, please see accompanying drawing, the associated jaw portion of jaw movable part (1) has an interior hexagonal hole, jaw fixture (4) is pinch bar just, its end and jaw movable part (1) are nested together, have one 120 ° breach in a termination portion that inserts jaw movable part (1), and have thread groove in the side of this end.120 ° of breach of jaw fixture (4) just in time can overlap with interior six sides' of jaw movable part (1) a angle.Jaw movable part (1) is equipped with knob (2) by minor axis (3), and the thread groove spiral on the screw thread of knob (2) and the jaw fixture (4) together.Rotation knob (2) by the effect of the thread groove on jaw fixture (4), makes jaw movable part (1) do the reciprocating motion of front and back along jaw fixture (4), so just can adjust the size of jaw, to adapt to the screw of different size specification.When jaw movable part (1) moves to foremost, 120 ° of breach of jaw fixture (4) just in time overlap with interior six sides' of jaw movable part (1) a angle, so at this moment the also screw of the full-size specification that can pull of this spanner just, when jaw movable part (1) when moving to rearmost end, jaw just merges to minimum.The utility model is that interior six sides contact screw when pulling the screw thread of full-size specification basically, all be four face contacts when pulling the screw of other dimensions, thereby the clamping screw is more firm.
Claims (1)
1, a kind of movable double offset ring spanner, form by jaw movable part (1), knob (2), minor axis (3), jaw fixture (4), the associated jaw portion that it is characterized in that jaw movable part (1) is six sides in, and jaw fixture (4) the termination portion in the jaw movable part (1) of being enclosed within is one 120 ° a breach.
