Abstract
The utility model relates to a machine tool, in particular to a triangular movable wrench. In the structure of the triangular movable wrench, the head fixing jaw of the wrench handle adopts an equiangular triangle, a groove is arranged in the middle of the right side of the equiangular triangle, a movable jaw is installed in the groove, the wrench handle adopts a hollow cylinder, a pushing rod is arranged in the wrench handle, the pushing rod is fixedly connected with the movable jaw, external thread is arranged at the lower part of the wrench handle, and a screw drum is hinged with the pushing rod. The triangular movable wrench has the advantages that the structure is simple, the operation is convenient, in addition, because the triangular movable wrench can always exert clamping force to bolts during working, the deformation or loosening of the wrench can not occur during the operation, thereby the triangular movable wrench can be widely suitable for the utilization in machinery, construction and manufacturing industries.
Description
(1) technical field
The utility model relates to a kind of machine tool, a kind of specifically three angle adjustable spanners.
(2) background technology
Widely used spanner has open spanner, Flexible spanner in mechanical industry at present, in use, is that two faces are stressed.Easy deformation is opened when stressed, and the hexagon with bolt head twists into circle.Double offset ring spanner and box spanner because interior shape fixes, the intensity of or bolt head and spanner itself irregular when bolt head, when hardness is not enough, also can twist into circle with hexagon.Bring great trouble to work, even the work that influences is proceeded.
(3) utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, use light, spanner a kind of three angle adjustable spanners that can not become flexible or be out of shape in use.The utility model is that the head fixed jaw of trigger piece is an equilateral triangle, has a groove in the middle of equilateral triangle the right, and movable jaw is installed in its groove.Trigger piece is a hollow cylinder, is provided with a push rod in trigger piece, and push rod and movable jaw are affixed; The trigger piece below is provided with external screw thread, is used to install the spiral drum.Spiral drum and push rod hinge joint.Advantage of the present utility model is simple in structure, uses lightly, and three angle adjustable spanners have a thrust to bolt at work all the time, so in use spanner can not be out of shape or be loosening, it is widely used in machinery, building, manufacturing and uses.
