Abstract

The utility model relates to a multifunctional spanner, a handle whose surface on one end is circular arc abutting arc formed is bar-shaped, and a bar-shaped aperture arranged on the handle is fixed with a driving end inside. The driving end in a shape of hook is fixed to the handle by a pin, the driving end can rotate along the pin after the fixation, and a pin hole is arranged on one end of the driving end; the pin hole matches with the pin to fix the driving end in the bar-shaped aperture of the handle. Two planes in an angle of 120 degree are arranged on the other end of the driving end, and are provided with teeth, a fixed pin arranged inside the bar-shaped aperture is provided with a spring. A work piece is arranged between the two planes of the driving end and the round arc plane of the handle, the spring pushes the driving end to rotate, and the work piece is automatically clamped; the work piece is clamped by three planes, and the driving end is pushed to screw or loose the work piece. The utility model has the advantages that the work pieces in different types can be clamped, and the range of application is wide.

Description

Multipurpose wrench
Affiliated technical field
The utility model relates to the instrument that a kind of dismounting, when maintenance are used, and especially relates to a kind of tightening or the multipurpose wrench of loosening fasteners, pipe fitting.Can tighten or unclamp bolt, nut, also can be used for clamping, rotate circular pipe fitting, promptly tighten or unclamp pipe fitting etc.This multipurpose wrench has the function of multiple instruments such as adjustable wrench, fork spanner and pipe wrench.The operator can tighten or unclamp bolt, nut more easily, also can tighten or unclamp pipe fitting, and has and make characteristics such as simple, and becomes the new design with practical row, is suitable for applying.
Background technology
At present, the instrument of the employed turn Fastener of pincers worker mainly is adjustable wrench, fork spanner, box spanner and double offset ring spanner.This class instrument that the plumber uses is pipe wrench mostly.These instruments all are the tradition of rotational workpieces and effective tool, but a kind of instrument can only be at the workpiece of a certain given configuration, is to be that hexagonal part that is rotated works at profile as spanner, as nut, clamping, the circular pipe of rotation are at a complete loss as to what to do, and the scope of application is little.Be rotated screwing, unclamping of part for what finish multiple shape, need to prepare multiple spanner.It is very inconvenient to carry multiple instrument; In addition, adjustable wrench and pipe wrench need to be adjusted openings of sizes when the part of chucking different size, adjust improperly sometimes, need take out and adjust openings of sizes again, waste time and energy delay time at stop, inefficiency.
The utility model content
The purpose of this utility model is to overcome the existing workpiece spanner of tightening, unclamp, can only be at the workpiece of certain given configuration, and the deficiency that the scope of application is little; The part that overcomes existing spanner chucking different size in addition must be adjusted openings of sizes, wastes time and energy ineffective deficiency.A kind of multipurpose wrench is provided, and this multipurpose wrench can not only be tightened, unclamp profiles such as bolt, nut is the hexagon workpiece, and can also tighten, unclamp profile is cylindrical pipe fitting, and need not adjust openings of sizes when using.
A kind of tightening or the multipurpose wrench of loosening fasteners, pipe fitting, handle one end surfaces is circular arc and connects arc shape.Strip hole is arranged on the handle. be fixed with driving end in the strip hole.Being shaped as of driving end is hook-shaped.One end of driving end has pin-and-hole, and pin-and-hole cooperates with pin, driving end is fixed in the bar hole of handle.The other end of driving end has two planes, and two planes are 120 degree angles, and tooth is arranged on the plane.Spring is arranged on the steady pin.Workpiece is placed between the arc surface of two planes of driving end and handle the no good rotational automatic chucking workpiece of spring at hand.Driving handle is also tightened or is unclamped workpiece.
The beneficial effects of the utility model are, are two planes of 120 degree because the utility model driving end has angle, have tooth can tighten different workpiece on two planes.Overcome existing spanner, can only be at the workpiece of certain given configuration, the deficiency that the scope of application is little.Needn't adjust the wrench opening size by the workpiece size in addition, just can block workpiece automatically, overcome and now to adjust openings of sizes to adapt to the shortcoming of workpiece before existing spanner tightens part.The utility model multipurpose wrench can tighten six square nuts, can also tighten profile and be cylindrical pipe fitting, and is applied widely.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is a structural representation of the present utility model.The spring (7) that adopts is a torsionspring.
Accompanying drawing 2 is structural representation circles of the present utility model.The spring (7) that adopts is different with accompanying drawing 1, employing be extension spring.
Among the figure, 1. driving end, 2. plane, 3. upper surface, 4. pin, 5. strip hole, 6. spring, 7. steady pin, 8. handle.
The specific embodiment
Embodiment 1, as Fig. 1, Fig. 2.The handle of multipurpose wrench (8) length is 300 millimeters, and wide is 20 millimeters.Handle (8) upper surface (3) is circular arc and connects arc shape.In the middle of the handle (8) bar hole (5) is arranged, the width of bar hole (5) is 6 millimeters, and length is 55 millimeters.In hole (8), be fixed with driving end (1).Driving end (1) is that pin (4) is fixing with the fixed form of handle (8).It is 8 millimeters pin hole that diameter is arranged on driving end (1) and the handle (8).Can rotate along pin (4) with pin (4) fixing back spanner (1) head.Being shaped as of driving end (1) is hook-shaped, and thickness is 11 millimeters.One end of driving end (1) has two planes (2), and two planes (2) are 120 degree angles, and it is the tooth of 1.5 millimeters deep that the degree of depth is arranged on plane (2).Steady pin (7) is arranged in bar hole (5), torsionspring (6) is arranged on the steady pin (7).
Embodiment 2
Substantially identical in embodiment 1, difference is: handle (8) upper surface (3), promptly connect tooth on the face of camber line at circular arc, and the degree of depth of tooth is 1 millimeter.Spring (6) is an extension spring, and an end of extension spring is fixed on the steady pin (7), and the other end is fixed on the end of driving end (1).
