Abstract

The invention discloses a multi-functional casting. The multi-functional casting comprises a central connecting ring, connecting rods, a large-size open spanner end portion, a small-size open spanner end portion and a sleeve hole with a square opening, wherein a square through hole is formed in the middle position of the central connecting ring, the number of the connecting rods is three, one end of each connecting rod is combined with the outer circle of the central connecting ring, the large-size open spanner end portion is connected with an end portion of one of the connecting rods, the small-size open spanner end portion is connected with an end portion of another connecting rod, and the sleeve hole with the square opening is connected with an end portion of the third connecting rod. Through the method, the multi-functional casting not only has the flexibility of an open spanner, but also can be used in cooperation with a sleeve with a square opening, the application defects of an ordinary sleeve rotating rod are overcome, and the application range of the sleeve with the square opening is further expanded.

Description

technical field [0001] The invention relates to the field of casting tool design, in particular to a multifunctional casting. Background technique [0002] The socket wrench is easy to use and has a variety of specifications, and a socket rod can match socket heads of various sizes. It is easy to replace, saves raw materials, and is easy to organize and carry. Therefore, socket wrenches are replacing Traditional open end wrench or ring wrench. [0003] The square head socket is a kind of socket wrench. It is characterized in that the upper part of the socket head is a square column, and the lower part is a nut sleeve hole of various specifications. It is reliably connected with the socket rod and has a wide range of applications. However, the form of the connecting rod is single, and it cannot function normally in some specific occasions, or the requirements for the spatial position of the nut are different when the square socket and the open end wrench are used.
