Specific implementation mode
Detailed description for the present invention and technology contents, cooperation description of the drawings is as follows, however attached drawing is only to refer to and say
It is bright to be used, it is not intended to limit the present invention.
As shown in figures 1 to 6, a kind of quick-acting pipe tongs with gearshift function, including：Moving caliper 1, fixed caliper 2, torsional spring
3, glue handle 4, button 5, plus screw 6, compression spring 7, tack axis pin 8,2 head of fixed caliper are set there are two circular hole, in two circular holes
Between be equipped with rectangle elongated slot, 1 back of moving caliper is equipped with pressing protrusion, and tail portion is equipped with circular hole and side and is equipped with torsional spring slot, another
Side is equipped with pressure spring slot, and button 5 is penetrated from one mother rib lateral rotundum of torsional spring slot of moving caliper 1, and torsional spring 3 is fixed on to the torsion of moving caliper 1
In spring slot, tack axis pin 8 is penetrated from one mother rib lateral rotundum of pressure spring slot of moving caliper 1, and the size equipped with two sections of diameters of thickness, with
Button 5 is riveted together, and plus screw 6, which is connected through a screw thread, is fixed on compression spring 7 in the pressure spring slot of moving caliper 1, compression spring 7
The other end is pressed on the end face of tack axis pin 8.
As shown in Figure 3：1 back of moving caliper be equipped with pressing protrusion, when operator with thumb press live the protrusion and to
Under with strength when, moving caliper 1 will be clockwise rotated down around tack axis pin 8, the torsional spring 3 being sleeved at this time on tack axis pin 8
Power will be squeezed and compressed, the opening size of pipe wrench will become larger rapidly at this time, various sizes of workpiece is clamped, work as pipe
In nesting after workpiece, as long as operator unclamps the thumb of force, extruded torsional spring 3 will discharge elastic force at this time, and then drive
Moving caliper 1 rotates up counterclockwise around tack axis pin 8, therefore just Automatic-clamping workpiece, progress are continuous rapidly anti-for pipe wrench
Multiple spine twists operation.
In addition, tack axis pin 8 is equipped with the size of two sections of diameters of thickness, when its major diameter dimension is located at a left side for fixed caliper 2
When in the circular hole of lower section, pipe wrench is in the state of small gear amount of opening, and the size of the pipe wrench clamping workpiece is in 10mm to 26mm at this time
Within the scope of this.
As shown in Figure 4：When operator firmly presses button 5 on earth, since button 5 and tack axis pin 8 are to be riveted on one
It rises, so tack axis pin 8 is jacked up, to apply pressure to compression spring 7, the small-diameter sized of tack axis pin 8, which is located at, at this time fixes
In the lower left circular hole of caliper 2, operator, which can take advantage of a situation, pushes button 5 to upper right side, the small-diameter sized of tack axis pin 8
2 rectangle elongated slot of fixed caliper can be slipped over to enter in the upper right side circular hole of fixed caliper 2, while being sleeved on the minimum of tack axis pin
Torsional spring part on diameter shaft part also can guarantee to be passed through in rectangle elongated slot, to also drive moving caliper 1 to fixed caliper 2
Upper right side is moved, it is achieved that the function of this pipe wrench crash change of speed.Operator discharges the pressing to button 5 at this time,
Under the effect of 7 pressure of compression spring, tack axis pin 8 resets, and then button 5 is jacked up again, and pipe wrench is in big gear amount of opening at this time
State, the size of clamping workpiece is in 26mm to 44mm within the scope of this.
Similarly, when button 5 firmly press on earth by operator, while taking advantage of a situation that lower section pulls to the left by button 5, to also drive
Moving caliper 1 is moved to the lower left of fixed caliper 2, it is achieved that this pipe wrench is rapidly switched to small gear amount of opening
State.
In addition, the shank of the present invention uses the scheme of set glue handle 4, and to use rigid plastics PP+ soft for the glue handle 4
The combining form of plastics TPR, the shank of fixed caliper 2 use the design style of multistage groove, to increase the chimeric of glue handle 4
Power, rigid plastics PP be in order to increase the intensity and pulling capacity of shank, with ensure operator when in use can not by glue handle 4 from
It is extracted in fixed caliper 2, the design of flexible plastic TPR uses cellular design style, is to ensure that operator makes
Used time being capable of damping energy-absorbing.The cambered design of the outer profile of glue handle 4 uses base of principle of human engineering simultaneously, ensure that operator
Comfort level when gripping.
In conclusion reasonable design of the present invention, simple in structure, easy to manufacture, using, it is easy to operate, it is time saving and energy saving, both may be used
To realize the function of fast clamp workpiece, and rapid gearshift function may be implemented, it, can be to pipe various sizes of workpiece is clamped
The progress of the workpiece such as part, bolt, nut is continuous, and rapidly spine twists repeatedly, substantially increases the working efficiency of operator.
The foregoing is merely presently preferred embodiments of the present invention, and non-to limit the scope of the claims of the present invention, other are with this
The equivalence changes of patent of invention spirit should all belong to the scope of the claims of the present invention.
