The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, single hand operation movable wrench of the present invention comprises handle 1, fixed caliper 2, moving caliper 3, bolt 4, nut 5, knob 6, lever 7 and spring 8.
The front end of the handle 1 among the present invention is provided with the slotted hole 12 that slides a structure 11 and a perforation consistent with line of travel that slides for moving caliper 3.Slide two long slot bores 112 that structure 11 comprises a step slide rail 111 and runs through slotted hole 12 both sides.Slotted hole 12 is the reducing hole, comprise four different diameter segment from begin order near knob 6, the diameter of first section diameter and knob 6 is suitable, the diameter of second section diameter and nut 5 is suitable, the 3rd section the diameter and the diameter of bolt 4 are suitable, the 4th section the diameter and the diameter of spring 8 are suitable, and wherein first section the shortest and form the fore shaft of nut 5, second section long and suitable with the stroke of moving caliper 3.
Fixed caliper 2 among the present invention is provided with a long slot bore 21 that is used for ccontaining lever, and the front end of this long slot bore 21 connects the jaw of fixed caliper, and the rear end is communicated with the slotted hole 12 of handle 1 front end.On the jaw of fixed caliper, be provided with the step 22 that is used for ccontaining lever stress piece.
Moving caliper 3 among the present invention is erected at sliding on the structure of handle front end and passes two long slot bores 112 respectively from both sides by a pair of pin 31 and is fixedly linked with nut 5, and moving caliper can be driven along sliding structure by nut 5 and slide.Moving caliper 3 with slide the part that structure 11 is connected and be the frame-shaped structure adaptive with sliding structure, its Outboard Sections is an entity structure, make the position of the center of gravity (among Fig. 3 shown in the stain) of this moving caliper 3 corresponding to binding nut, thereby form certain moment of torsion sliding the structure place, avoid the effect lower slider of moving caliper at own wt.
Cooperation is referring to Fig. 4, Fig. 5, lever 7 among the present invention is arranged in the long slot bore 21 of fixed caliper 2 and by a bearing pin 72 and is connected on the fixed caliper and can rotates around this bearing pin, the front end of lever 7 is provided with a force block 71, this force block stretches out inboard and be positioned on the fixed caliper jaw on the corresponding step 22 at the jaw of fixed caliper 2, and the width of jaw of its length and fixed caliper 2 is suitable.The tail end of lever 7 contacts with the front end projection 42 of bolt 4 and links to each other.
The operation principle of single hand operation movable wrench of the present invention can be described as follows in conjunction with Fig. 6, Fig. 7:
During work, turn knob 6 moves up nut 5, drives moving caliper 3 by pin 31 (cooperate referring to Fig. 1) and also moves upward, and stops after touching workpiece A, as shown in Figure 6.Downward dextrorotation clamping of workpieces, rotate to certain angle after, reverse rotation again, during reverse rotation, workpiece A just touches the force block 71 of lever 7, and the other end will be oppressed the projection 42 of bolt 4, bolt 4 is moved downward, thereby be with moving caliper 3 to move downward together, as shown in Figure 7.After stopping reverse rotation, because the effect of spring 8, move upward with clamping work pieces again the realization ratcher function together thereby drive bolt 4 and moving caliper 3.The action that so moves in circles can be implemented under the situation of not taking out spanner workpiece is screwed.
