Abstract
The utility model relates to a ring spanner whose force arm and size are adjustable, which comprises a replaceable ring spanner(2)which is provided with connecting male threads, a sleeve(3)provided with connecting female threads at both ends, and an extension bar(4) provided with connecting male threads. The ring spanner(2) provided with connecting male threads can be replaced with different types of ring spanners according the size of the practical nut, and the sleeve(3)and the extension bar(4) can be installed to extend the force arm according to practical needs. The ring spanner set is small in volume, light in weight and convenient to take and is particularly suitable for outgoing repair work.
Description
Technical field
The utility model belongs to the hardware ﹠ tools field, relates to the double offset ring spanner of a kind of adjustable force arm and size.
Background technology
At present, the double offset ring spanner arm of force commonly used is all shorter, serious or when needing big moment when running into the nut corrosion, common way be at very thick long sleeve pipe that can encase this termination portion of double offset ring spanner other end cover with the arm of force that extends, though also can deal with problems, because of casing diameter excessive, cause the sleeve pipe volume big and heavy, very inconvenient when going out to repair, in addition, this method causes the sleeve opening cracking easily.
Summary of the invention
The utility model provides the double offset ring spanner of a kind of adjustable force arm and size, and this double offset ring spanner volume is very little, in light weight, and whole external member not may be split into three joints the time spent, is easy to carry.
The double offset ring spanner of adjustable force arm that the utility model provides and size comprises spanner, sleeve pipe and extension bar, and two of described sleeve pipe is connected with spanner and extension bar by screw thread respectively.
The double offset ring spanner of adjustable force arm that the utility model provides and size, of being connected with sleeve pipe of described spanner is that external screw thread is processed.
The double offset ring spanner of adjustable force arm that the utility model provides and size, two of described sleeve pipe is an internal thread machining.
The double offset ring spanner of adjustable force arm that the utility model provides and size, of being connected with sleeve pipe of described extension bar is that external screw thread is processed.
The utility model is connected with sleeve and company commander's bar by the threaded spanner of processing, and volume is very little, and weight is also light, and whole external member not may be split into three joints the time spent, is easy to carry.Spanner can be selected different specifications as required for use, and sleeve pipe can be selected different length for use according to actual needs with extension bar.
