Problems solved by technology

However, when this type of nut is generally tightened, two nuts need to be tightened in the same direction at the same time. In some cases, two nuts need to be tightened in the opposite direction at the same time. However, ordinary wrenches on the market cannot meet the requirements of tightening such nuts at the same time. There is no wrench that can tighten the double nuts in the same direction at the same time and can also tighten the double nuts in the opposite direction at the same time

Embodiment Construction

[0017] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] A double nut tightening lock wrench of the present invention comprises a worm wheel 4, a casing 5, a top cover 3, a worm 1, a one-way clutch 2 and a handle 6; the casing includes a locking nut tightening structure 7 and a main nut tightening structure 8, The lock nut tightening structure 7 is located above the main nut tightening structure 8. The lock nut tightening structure 7 is a semi-circular ring with double ears. The worm wheel 4 is installed in the semi-circular ring. There are 6 holes with small teeth, and the small teeth are evenly arranged. There is a hole at the center of the worm wheel 4. The shape of the hole is the shape obtained after two regular hexagons intersect concentrically at 30 degrees. It is pressed into the casing 5 through the top cover 3,...

Abstract

The invention provides a double-nut screwing and locking wrench. The double-nut screwing and locking wrench comprises a worm wheel, a shell, a top cover, a worm, a one-way clutch and a handle. A mainnut is screwed down by the use of small teeth on the shell, a locking nut is screwed down by the use of teeth in the worm wheel, and therefore the purpose that the two nuts are screwed down at the same time is achieved. In the perpendicular direction, the handle is held and pressed, a worm wheel and worm mechanism is driven to move, and therefore the purposes that the nut in the shell does not move, and the nut in the worm wheel is screwed down in the reverse direction are achieved. When the nuts are screwed down in the reverse direction, the nuts can be screwed down through one-hand operation, and a worker working aloft can more conveniently work and is safer.

Description

technical field [0001] The invention relates to the field of mechanical wrenches, in particular to a double-nut tightening locking wrench. Background technique [0002] A wrench is a commonly used installation and removal tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts, and other openings or casings that are threaded to hold bolts or nuts. [0003] At present, there are some lock nuts on the market that use double nuts on top or use different principles of the lead of the coarse nut and the fine thread nut to realize the tightening and locking of the double nuts. However, when this type of nut is generally tightened, two nuts need to be tightened in the same direction at the same time. In some cases, two nuts need to be tightened in the opposite direction at the same time. However, ordinary wrenches on the market cannot meet the requirements of tightening such nuts at the same time. There is no wrench that can simultaneously tighten ...
