Abstract
The utility model relates to a portable type a grip wrench. The utility model is composed of a movable wrench jaw (1), a fixed jaw (2), a movable hinge (4), a positioning body (5), a nut (6), a wrench body (9), a locking nut (10), a locking block (11), and movable wrench handles (12). The utility model is characterized in that the fixed jaw (2) is connected to the wrench body (9) in an interference fit by rivets (3); a support (7) for the fixed jaw is fixedly connected to the front end of the wrench body (9). Thus, the utility model has the advantages of simple processing technology, low labor intensity, small size, light weight, portability, long service life, and low cost, and is especially suitable for different torques and various strained environments.
Description
The utility model relates to a kind of manual apparatus, particularly a kind of portable pipe vice.
At present, the forging and pressing handle pipe vice of domestic use pincers handle body heaviness, processing technology complexity, growth labour intensity is big, pincers handle body is longer, needs big loose tool, main equipment in forging process, causes the wasting of resources, because volume is big, weight is big, be not easy to carry, and regular jaw and pincers handle one, can not change, thereby the life-span is short, the cost height.
The purpose of this utility model will provide a kind of processing technology simple exactly, productive labor intensity is little, volume is little, in light weight, be easy to carry, long service life, portable pipe vice that cost is low.
The purpose of this utility model is achieved in that a kind of portable pipe vice, form by moving jaw (1), regular jaw (2), hinges (4), positioning body (5), nut (6), caliper (9), locking nut (10), latch segment (11), adjustable clamp handle (12), it is characterized in that described regular jaw (2) is connected on the caliper (9) by rivet (3) interference fit, regular jaw support (7) is fixedly connected on the front end of caliper (9).
Optimum implementation of the utility model: adjustable clamp handle (12) is movably connected in the caliper (9) by locking nut (10), latch segment (11).
The utility model compared with prior art has the following advantages:
1, owing to adopt regular jaw (2) to be connected form on the caliper (9) by rivet (3) interference fit, thereby impaired jaw can change at any time, and long service life, cost are low.
2,, thereby can increase the strength of caliper (9) because employing regular jaw support (7) is fixedly connected on the form of caliper (9) front end.
3, owing to adopt adjustable clamp handle (12) to be movably connected in the interior form of caliper (9) by locking nut (10), latch segment (11), thus volume little, in light weight, be easy to carry.

Embodiment:
Moving jaw (1), positioning body (5), nut (6), the power that disappears spring (8) are with existing pipe wrench, and locking nut (10), latch segment (11) adopt 45
#Steel or steel alloy are processed into, and regular jaw (2) is connected on the caliper (9) by rivet (3) interference fit, and regular jaw support (7) is fixedly connected on the front end of caliper (9), connect pincers handle (12) by nut (10) latch segment (11) in the caliper (9).
During use, turn adjusting nut (6) makes the moving jaw lengthwise movement, reaching the opening size of clamping garden pipe, increases moment as need, and the reverse locking nut that unclamps is twitched the adjustable clamp handle, determine length after, turn clockwise and tighten nut.Latch segment moves vertically, produces active force with the tubular type caliper, makes it to clamp Telescopic handle, can use.
Claims (2)
1, a kind of portable pipe vice, form by moving jaw (1), regular jaw (2), hinges (4), positioning body (5), nut (6), caliper (9), locking nut (10), latch segment (11), adjustable clamp handle (12), it is characterized in that described regular jaw (2) is connected on the caliper (9) by rivet (3) interference fit, regular jaw support (7) is fixedly connected on the front end of caliper (9).
2, portable pipe vice according to claim 1 is characterized in that described adjustable clamp handle (12) is movably connected in the caliper (9) by locking nut (10), latch segment (11).
