Abstract

The utility model provides an adjustable radial hook-shaped wrench, which comprises a handle, a reinforced rib, a hook head and a beam section type stressing rod; when the radial hook-shaped wrench works, a bolt and a nut on the hook head can be loosened, and after the hook head moves along a straight line U-shaped sliding chute to a position that a cylinder is matched with a round block slot of a round nut, the bolt and the nut are screwed again, and then the wrench can be used. The wrench provided by the utility model can be used for making up the disadvantage of the existing manual wrench; the wrench satisfies the actual demand and is simple in structure.

Description

A kind of adjustable radially hook-shaped spanner

Technical field

The utility model relates to a kind of manual wrench, specifically, is a kind of adjustable radially hook-shaped spanner.

Background technology

Spanner is an instrument of tightening or unscrew screw, nut etc., is to utilize lever principle to twist bolt, screw, nut and other screw threads tightly to hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is shaped on clamp holder portion usually and applies the external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut are held bolt or nut.Apply external force along the screw thread rotation direction at shank during use, just can twist bolt or nut.Wherein, Manual wrench is common wrench again; Be mainly used in the common life and work; Its use is fairly simple, mainly is divided into single head fork spanner, double ended spanner, adjustable wrench, double offset ring spanner, combination wrench, knocks spanner, box spanner, sleeve driver, torque spanner, torque wrench, cross like spanner, ratchet spanner, hook-shaped spanner, inner hexagon spanner, interior cubic spanner, manual clutch formula torque wrench, bulldog wrench, T type spanner, L type spanner, trident spanner, knuckle buster, oil drum spanner, tyre wrench, spanner for spark plug, cleaner spanner, combination wrench, other spanners etc.Torque wrench is divided into news and rings spanner, pointer spanner, digital display spanner.

The use of manual wrench is selected corresponding spanner for use according to the characteristics of fastened securing member.Screw, with holding the spanner handle end, clockwise direction is firmly screwed; Unscrew, counterclockwise revolve.The manual wrench characteristics be simple to operate, price is low, model and specification are various.However, often can not satisfy actual needs.

Summary of the invention

In order to address the above problem, the utility model provides simple in structure and adjustable radially hook-shaped spanner that the scope of application is wide is separated the problem that must not satisfy actual needs.

In order to achieve the above object, the technical scheme of the utility model employing is:

The utility model is a kind of adjustable radially hook-shaped spanner, comprises handle, and the front end of handle is set to straightway " U " shape chute and arc section; On straightway " U " shape chute with the fastening eave tile of bolts and nuts; Eave tile comprises the nut of cylinder and stationary cylinder, connects a round nut in the eave tile bottom; Both sides are provided with a pair of circular draw-in groove on round nut, put the bundle joint formula boosting-rod of an increase moment of torsion at said handle rear end.

The arc of hook-shaped spanner is divided into arc section and two sections of straightways and makes eave tile into the fastening dismoutability of screw bolt and nut cylinder, this cylinder physical efficiency slides in " U " of straightway shape chute; On handle, can put bundle joint formula boosting-rod to increase moment of torsion, on the round nut of this hook-shaped spanner applicable to different-diameter, reach the wide effect of the scope of application.

The beneficial effect of the utility model: on handle, can put bundle joint formula boosting-rod to increase moment of torsion, simple in structure on the round nut applicable to different-diameter, easy to make, reach the wide effect of the scope of application.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the cutaway view Amplified image of the utility model round nut 3.

Fig. 3 is the A-A cutaway view Amplified image.

The 1-handle is wherein arranged, 2-reinforcement, 3-round nut, 11-straightway " U " shape chute, 12-arc section, 4-eave tile, 5-bundle joint formula boosting-rod, the circular draw-in groove of 31-, 41-cylinder, 42-nut

The specific embodiment

In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.

Like Fig. 1,2 and 3, the utility model is a kind of adjustable radially hook-shaped spanner, comprises handle 1; The front end of handle 1 is arranged to straightway " U " shape chute 11 and arc section 12, and eave tile 4 is anchored on " U " shape chute 11 with bolts and nuts, and arc section 12 is integral structures with straightway " U " shape chute 11; Handle 1 rear end puts bundle joint formula boosting-rod 5 to increase moment of torsion, at arc section 12 and handle 1 outside welding reinforcement 2, increases the rigidity and the stability of handle 1; Eave tile 4 comprises cylinder 41; Nut 42 with fixing said cylinder 41 connects a round nut 3 in eave tile 4 bottoms, and both sides are provided with a pair of circular draw-in groove 31 on said round nut 3; 31 one-tenth of cylinder 41 and circular draw-in grooves movingly, this hook-shaped spanner material therefor is a chrome-vanadium steel.

When this radially hook-shaped spanner is worked; As long as the bolts and nuts on the eave tile 4 42 are unclamped; And after it is moved to the circular draw-in groove 31 suitable positions that cooperate that make cylinder 41 and the circular draw-in groove 31 of round nut 3 along straightway " U " shape chute 11; Tight a bolt again and nut 42, just can carry out operation.

On the round nut of this hook-shaped spanner applicable to different-diameter, reach the wide effect of the scope of application.
