Connection piece wrench

Abstract

The invention relates to the field of dismounting tools and discloses a connection piece wrench characterized by comprising a driving part (30) and a screwing part (40). The driving part (30) comprises an input shaft (31); the screwing part (40) is formed by a connection piece cooperating part (42) arranged on the screwing part (40); the output shaft (31) can drive the connection piece cooperating part (42) of the screwing part (40) to rotate surrounding a rotating axis of the connection piece cooperating part (42); and a rotating axis of the output shaft (31) and the rotating axis of the connection piece cooperating part (42) are non-collinear. The rotating axis of the output shaft and the rotating axis of the screwing part are non-collinear, so the output shaft does not affect movements of the connection piece and the connection piece can be continuously driven to move in a long dismounting distance; the connection piece wrench can conduct long distance dismounting work, so dismounting work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a dismounting tool, in particular to a connector wrench for nuts with a large dismounting torque and a long dismounting distance. Background technique [0002] For the nuts in bolt connection or lead screw connection, the traditional disassembly tool is a wrench. According to its shape and function, the wrench is divided into various types such as ring wrench, socket wrench, adjustable wrench, and dead wrench. Bolts, screws, nuts, and other open or socketed fasteners with threads that hold bolts or nuts in place. In actual work, a wrench can be selected for disassembly and assembly according to different needs, and the common point of these traditional wrenches is that their power source comes from people, so they are quite energy-consuming tools for workers. In view of the time-consuming and labor-intensive problems of traditional wrenches, there are currently many electric wrenches to solve the above problems. The electric ...

Problems solved by technology

[0003] However, the axis of rotation of the output shaft and the nut is collinear, and the nut can only be disassembled within the depth of the sleeve, while the depth of the sleeve of the electric wrench is limited. Therefore, the electric wrench in the prior art can only be disassembled to expose the screw rod Short nuts, for nuts with long dismounting distance, such as the nuts mounted on the leading screw, because the length of some leading screws is up to 5 meters, the dismounting distance of the nut is also 5 meters. The electric wrench in the prior art The lead screw nut cannot be disassembled at all (theoretically, the nut can be disassembled over a long distance by extending the length of the sleeve, but in fact, if a 5-meter-long sleeve is installed, not only consumables, but also a larger power source than a hand-held motor is required , lack of economy), it can only be disassembled by manpower, and the screw nut bears a very large tightening force, so the disassembly operation is very intensive, time-consuming, laborious and inefficient
