Description
Technical field:
The present invention relates to pipe vice technical field of structures, relate in particular a kind of Multifunctional grip wrench.
Background technology:
Pipe vice is generally used for clamping and rotating steel tube class workpiece.Be widely used in textile machinery industry.Vising pipe makes it rotate connection.Its operation principle is that the conversion of pincers power is entered to torsion, and the power that is used in twisting direction also just clamps tightlyer more greatly.
Existing pipe vice is generally that the head in clamp handle is provided with a caliper and clamps pipe, its position can not be moved, thereby pulling clamp handle rotates pipe, it can only carry out monolateral operation with hand, while rotating like this, need to rotate and loosen afterwards caliper and press from both sides again and turn again, bother very much, particularly in pipe rotation effortless situation, operation has increased the workload operating more like this, has reduced efficiency.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and provide a kind of Multifunctional grip wrench, it is simple in structure, its caliper can move left and right on carriage release lever, when pipe rotates leicht fallen D/A, can two hands hold respectively the two ends of carriage release lever and carry out bimanualness, raise the efficiency, the encircling type clamping by upper clamp and lower clamp simultaneously improves its clamping effect.
Technology solution of the present invention is as follows:
A kind of Multifunctional grip wrench, comprise caliper, described caliper comprises upper clamp and lower clamp, the lower plane middle part of upper clamp forms the upper arc-shaped concave concaving, the upper in-plane of lower clamp successfully has the lower arc-shaped concave concaving, upper arc-shaped concave is corresponding up and down with lower arc-shaped concave, and upper arc-shaped concave and lower arc-shaped concave are toothed surface; Upper arc-shaped concave and lower arc-shaped concave form clamping mouth;
At least two set bolts are distributed in respectively the both sides of caliper, and it is bolted with hold-down nut through upper clamp and lower clamp, top successively;
The top of upper clamp and the bottom of lower clamp all form the through hole perpendicular with clamping Kou center axial line, and two carriage release levers are respectively through each self-corresponding through hole, and the two ends of carriage release lever are fixed with block.
Described carriage release lever is provided with contiguous block, top through hole and lower through-hole that the front side wall of contiguous block forms, on the rear wall of contiguous block, form central recess, top through hole and lower through-hole are connected with central recess, and two carriage release levers also stretch out contiguous block through central recess through its corresponding top through hole and lower through-hole respectively; In central recess, be inserted with two back-up blocks, the top of screw rod is that left hand thread, bottom are right-handed thread, the middle part of screw rod is hexahedron portion, the back-up block upper and lower part that the top of screw rod is screwed onto top is screwed onto on the back-up block of bottom, the back-up block on top is pressed against on the carriage release lever of top, the back-up block of bottom is pressed against on the carriage release lever of below, and clamp handle is bolted to connection on the middle part of the trailing flank of contiguous block.
The cross section of described carriage release lever is rectangle, and top through hole and lower through-hole are identical rectangular opening, and back-up block is cuboid piece, and the height of top through hole and lower through-hole is higher than the height in the cross section of carriage release lever.
The two ends of described carriage release lever have been bolted to connection block.
Beneficial effect of the present invention is:
1, it is simple in structure, its caliper can move left and right on carriage release lever, when pipe rotates leicht fallen D/A, can two hands holds respectively the two ends of carriage release lever and carries out bimanualness, raise the efficiency, the encircling type clamping by upper clamp and lower clamp simultaneously improves its clamping effect.
2, when pipe rotation needs larger torsion, by being located at contiguous block on two carriage release levers, and lengthening clamp handle is set on contiguous block, thereby strength when reduction operator hand is pulled reduces labour intensity.
3, the equal parts of the present invention are all detachable, when using very much, and the replacing of for convenience detach and parts.

The specific embodiment:
Embodiment: see shown in Fig. 1 to 6, a kind of Multifunctional grip wrench, comprise caliper 10, described caliper 10 comprises upper clamp 1 and lower clamp 2, the lower plane middle part of upper clamp 1 forms the upper arc-shaped concave 11 concaving, the upper in-plane of lower clamp 2 successfully has the lower arc-shaped concave 21 concaving, and upper arc-shaped concave 11 is corresponding Shang Xia 21 with lower arc-shaped concave, and upper arc-shaped concave 11 and lower arc-shaped concave 21 are toothed surface; Upper arc-shaped concave 11 and lower arc-shaped concave 21 form clamping mouth;
At least two set bolts 3 are distributed in respectively the both sides of caliper 10, and it is bolted with hold-down nut 4 through upper clamp 1 and lower clamp 2, top successively;
The bottom of the top of upper clamp 1 and lower clamp 2 all forms through hole 5, two piece carriage release levers 6 perpendicular with clamping Kou center axial line respectively through each self-corresponding through hole 5, and the two ends of carriage release lever 6 are fixed with block 7.
Described carriage release lever 6 is provided with contiguous block 8, the top through hole 81 that the front side wall of contiguous block 8 forms and lower through-hole 82, on the rear wall of contiguous block 8, form central recess 83, top through hole 81 and lower through-hole 82 are connected with central recess 83, and two carriage release levers 6 also stretch out contiguous block 8 through central recess 83 through its corresponding top through hole 81 and lower through-hole 82 respectively; In central recess 83, be inserted with two back-up blocks 84, the top of screw rod 85 is that left hand thread, bottom are right-handed thread, the middle part of screw rod 85 is hexahedron portion 851, back-up block 84 upper and lower parts that the top of screw rod 85 is screwed onto top are screwed onto on the back-up block 84 of bottom, the back-up block 84 on top is pressed against on the carriage release lever 6 of top, the back-up block 84 of bottom is pressed against on the carriage release lever 6 of below, and clamp handle 9 is bolted to connection on the middle part of the trailing flank of contiguous block 8.
The cross section of described carriage release lever 6 is rectangle, and top through hole 81 and lower through-hole 82 are identical rectangular opening, and back-up block 84 is cuboid piece, and the height of top through hole 81 and lower through-hole 82 is higher than the height in the cross section of carriage release lever 6.
The two ends of described carriage release lever 6 have been bolted to connection block 7.
Operation principle: hold-down nut 4 is unscrewed, pipe to be rotated is inserted to clamping mouth, then rotate hold-down nut 4, pipe is clamped between upper arc-shaped concave 11 and lower arc-shaped concave 21, then adjust carriage release lever 6, caliper 10 is positioned in the middle of carriage release lever 6, then with the two ends that two hands are held respectively carriage release lever 6, rotate, when pipe speed ratio more at need, can install clamp handle 9 additional, mounting means is, first the block on one end of two carriage release levers 67 is unloaded, by the top through hole 81 of contiguous block 8 and lower through-hole 82 sleeves on two carriage release levers 6, then, the middle part of clamping screw rod 85 by spanner is hexahedron portion 851, screw rod 85 is rotated, thereby the back-up block 84 that makes top is pressed against on the carriage release lever 6 of top, the back-up block 84 of bottom is pressed against on the carriage release lever 6 of below, complete fixing, then clamp handle 9 is bolted to connection on the middle part of the trailing flank of contiguous block 8, like this clamp handle 9 is installed, then just can pull clamp handle 9 has pulled, owing to having increased the length of pulling, just can reduce the power of pulling, not only can pull pipe rotates, simultaneously, also reduced the power of pulling the required operating personnel that pay.
