Modular large-torque wrench adjustable in turning angle

Abstract

The invention discloses a modular large-torque wrench adjustable in turning angle. The large-torque wrench comprises a monkey wrench head, a movable shank and a lengthening sleeve, wherein the movableshank is hinged with the upper end of the monkey wrench head, and the lengthening sleeve sheathes the movable shank; the front end of the monkey wrench head is a movable opening; the rear end face ofthe monkey wrench head is provided with a hinged seat II; the monkey wrench head and the movable shank are hinged, and a left-handed connector, a right-handed connector and a double-thread screw arematched between the monkey wrench head and the movable shank; a relative angle between the monkey wrench head and the movable shank can be changed by rotationally adjusting the double-thread screw inthreaded connection with the left-handed connector and the right-handed connector, and further, the operating space size of a plane on which the whole wrench is located is decreased; the movable shankis sleeved with the lengthening sleeve, and the movable shank and the lengthening sleeve are fixed together by a U-shaped bolt, so that the lengthening sleeve cannot slip from the movable shank whenthe lengthening sleeve is used, and moreover, the lengthening sleeve can be adjusted in relative position on the movable shank, so that the whole wrench is more flexible to use.

Description

technical field [0001] The invention relates to the technical field of hardware, in particular to an assembled large torque wrench with adjustable rotation angle. Background technique [0002] A wrench is a commonly used installation and removal tool. Hand tools for turning bolts, screws, nuts, and other open or socketed fasteners whose threads hold bolts or nuts tightly by the principle of leverage. Among them, the adjustable wrench, whose opening width can be adjusted within a certain size range, can screw bolts or nuts of different specifications, so it is more widely used, but it still has the following disadvantages in actual use: [0003] 1. The handle of the adjustable wrench has a certain length, which is inconvenient to use in some small areas, and cannot be used in some deep areas; [0004] 2. The handle length of the adjustable wrench is fixed and cannot be adjusted. When high torque is required, it is necessary to find an additional sleeve for socket use. In ma...

Problems solved by technology

[0003] 1. The handle of the adjustable wrench has a certain length, which is inconvenient to use in some small areas, and cannot be used in some deep areas;

[0004] 2. The handle length of the adjustable wrench is fixed and cannot be adjusted. When high torque is required, it is necessary to find an additional sleeve for socket use. In many cases, it is impossible to find a suitable sleeve to match it, and it is easy to slip when using it. , there is a certain risk
