Abstract
The utility model discloses a fast self-fastening multipurpose wrench, comprising a wrench claw, a spring tab, a screw bolt, a wrench rod and a connecting pin. The fast self-fastening multipurpose wrench makes a spring automatic clamping mechanism replaced by the existing adjustable wrench and a screw regulating mechanism of grip wrenches. The two lug bosses are arranged at the outside of the wrench claw, and a jaw is formed by two intersecting planes with isosceles triangle gear teeth and a fan-shaped cambered plane; the clamped work piece is formed to three-point stress; the fastness of the clamped work piece is increased. The utility model has the advantages of long service life, simple structure, flexible operation and high efficiency. The fast self-fastening multipurpose wrench can be used freely in small gap place.
Description
The utility model relates to manual hardware ﹠ tools, and particularly a kind of self-tightening clamping is fast also rotated the quick self-tightening all-purpose wrench of various rod and tube kind workpiece and spiral fastener.
At present monkey spanner and the pipe vice that generally uses all is by turn worm spiral mechanisms grip workpiece, and its complex structure, volume is clumsy, manufacturing cost is high.In addition, the moving worm screw of the hand-screw of need choosing is in use regulated the span of jaw size and often needs repeatedly to regulate and just can put in place, can not continuous operation, and it is time-consuming to require great effort, and function of use is single, and versatility is poor.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of quick self-tightening all-purpose wrench is provided, the rod and tube kind workpiece and the spiral fastener of its self-tightening clamping fast, rotation arbitrary shape.
Fig. 1 is the utility model front view;
Fig. 2 is the vertical view of Fig. 1;
Working state figure when Fig. 3 is the utility model clamping small diameter workpiece;
Fig. 4 is working state figure during diameter work piece in the utility model clamping;
Fig. 5 working state figure that is the utility model when the big workpiece of little gap place clamping.
By reference to the accompanying drawings implementer's case of the present utility model is described below: a kind of fast self-fastening all-purpose wrench is made up of plate pawl (1), spring leaf (2), bolt (3), plate stem (4), connecting pin (5); The anterior inboard jaw of said plate pawl (1) has two intersecting planes with the isosceles triangle tooth (I, II), there is two-stage boss (B, C) in the anterior outside of plate pawl (1), plate pawl (1) rearward end is connected movingly with connecting pin (5), and is positioned in plate stem (4) the middle front part dead slot by connecting pin (5); Plate stem (4) leading section inboard is the fan-shaped cambered surface (III) with the isosceles triangle tooth, and connecting pin (5) is installed and is fastened in plate stem (4) the middle front part dead slot, Spring leaf (2) one ends are fastened on plate stem (4) middle part with bolt (3), and the other end withstands in plate pawl (1) the rearward end cambered surface with elastic force.
Angle of cut θ=55 of plate pawl (1) anterior inboard jaw plane (I) and plate pawl (1) forward terminal (A) and connecting pin (5) axle center (O) line OA °～70 ° of angles.The angle of cut of plate pawl (1) two intersecting planes of anterior inboard jaw (I, II) is 120 °, with traditional wrench or pipe vice to be held workpiece by 2 stressed become 3 stressed, increase the fastness of holding workpiece and improved the force-bearing situation of plate pawl (1), when plate stem (4) when turning clockwise, connecting pin (5) is also with the equidirectional rotation of plate stem (4), make the aperture of jaw that the trend that reduces, holding workpiece more firmly be arranged.When plate stem (4) inhour was rotated, the counter-force that acts on the jaw was opened jaw, and wrench freely purl rotates and can not drive workpiece.For convenience the rod and tube kind workpiece and the spiral fastener of clamping arbitrary shape, size, jaw outer end aperture AG line should be a bit larger tham between the bite of gripped object apart from EF.
The effect that the fan-shaped isosceles triangle flank of tooth is made in plate stem (4) leading section inboard is reasonable distribution jaw stress, rotation along with plate pawl (1), span of jaw can steplessly change, when being held workpiece size from little change when big, stress point on the fan-shaped tooth surface (III) just can be correspondingly shifted to (H) increment (referring to Fig. 3-shown in Figure 5) by (G) increment, and this reasonable force distribution can prolong the service life of wrench.Above-mentioned mentioned isosceles triangle tooth, its addendum angle are 65 ° of-75 ° of angles, adopt the effect of isosceles triangle tooth to be to protect to be held surface of the work not pulled, and can avoid taking place in the course of work skidding again.
The effect of the two-stage boss (B, C) in the anterior outside of plate pawl (1) is when the utility model wrench works in place, little gap, can open to help jaw by pulling boss (B) or boss (C), implements clamping or disengaging to workpiece.
Advantage of the present utility model is to be made up of two intersecting planes and a fan-shaped cambered surface in order to the jaw of holding workpiece, all arranging the isosceles triangle tooth on three faces, make be held workpiece form 3 stressed, during work, neither pull workpiece skidding does not take place yet, improve the fastness of holding workpiece, prolonged wrench service life.The anterior outside of plate pawl (1) is provided with the two-stage boss, and wrench can be operated freely under place, little gap.That this wrench also has is simple in structure, operation fast and flexible, advantage that efficient is high.
Embodiment of the present utility model:
Referring to Fig. 1, shown in Figure 2, with plate pawl (1), plate stem (4) difference forging forming, the isosceles triangle tooth at jaw place is processed by gear shapping machine, and plane (I) intersects the hexagonal angle degree with plane (II).With connecting pin (5) plate pawl (1) is positioned plate stem (4) middle front part dead slot place, connecting pin (5) and plate pawl (1) are for being connected movingly, connecting pin (5) is connected for stationary fit with plate stem (4), with bolt (3) spring leaf (2) one ends are fixed on plate stem (4) middle part, spring leaf (2) other end withstands in plate pawl (1) the rearward end cambered surface with elastic force, promptly becomes a quick self-tightening all-purpose wrench.At this moment, (A), (O) end line OA and plane (I) angle of cut θ=60 ° of angles.In the present embodiment, the isosceles triangle tooth addendum angle of jaw plane (I, II) is 75 ° of angles, and the isosceles triangle tooth addendum angle of fan-shaped plan is 65 ° of angles.
