In；Its structure designing points is that one end of described fixed jaw is provided with sleeve hole, is provided with spacing fixing groove, fixed jaw in sleeve hole
Pressing from both sides the jaws relative with movable jaw and be respectively equipped with triangle clip slot, triangle clip slot is longitudinally disposed.Said structure is easy to solid
Determine jaw and movable jaw passes through the triangle clip slot in dop, and dop and clamps the hexagonal of hex nut or hex screw
External diameter, thus by connecting the sleeve handle of this adjustable bushing, drive this adjustable bushing, and hex nut or hex screw turn
Dynamic.
It is provided with horizontal corrugated anti-skidding asperities in the jaws that described fixed jaw is relative with movable jaw.Said structure
Identical with the anti-skid structure of existing similar adjustable wrench, there is anti-skidding and ratcheting fixing function；Simultaneously facilitate hex nut, hexagonal
The hexagonal external diameter of screw clamps at same plane with this adjustable bushing, and rotates.
The sleeve hole of described fixed jaw closes with the square sleeve headgear of sleeve handle one end collet head, and collet head is arranged at set
The screwdriver bit hole of cylinder handle one end, collet head passes through lever knob limiting locking in sleeve handle.Said structure is a kind of easy
Socket wrench structure, it also can use existing similar socket wrench structure.
The other end of described sleeve handle is provided with the slow-witted mouth of U-shaped, circular spinous foramen running-on, adjustable wrench or tup.On
State structure and combine the structure of existing multifunctional wrench, except making sleeve handle be applicable to this adjustable bushing, also can have slow-witted mouth
Spanner, spinous foramen spanner, adjustable wrench and the function of hammer.
The sleeve hole side of described fixed jaw is provided with Universal sleeve head, i.e. Universal sleeve head by two joint union joints by hinged
Composition, one end union joint is provided with interface, and it is pullover that other end union joint is provided with square；Described Universal sleeve head or with fixed jaw even
It is integrated.Universal sleeve head uses 1/2'', 1/4'', 3/8'' or 3/4'', and Universal sleeve head is easy to two joint union joints foldings to be made
With.
This utility model reasonable in design, easy to use, production cost is low, and the box spanner scope of application is wide, is suitable for
The hex nut of many sizes or hex screw；It is suitable as box spanner adjustable bushing use, or with corresponding sleeve barrel spanner
Hands is used in combination.
