Description
Technical field
The utility model relates to a kind of spanner, and specifically a kind of bendable box spanner, belongs to machine tool technical field.
Background technology
Box spanner is made up of multiple multiple members such as sleeve and handle and connecting rod with hexagon ring or 12 jiaos of holes, be specially adapted to dismounting and fastening space of living in is very narrow or cave in very bolt or the nut of depths.
In machine work, often need to use box spanner to dismantle with fastening bolt or nut.Due at present produce and life in the structure of widely used box spanner generally all fix, use existing box spanner bolt or nut dismantles and fastening in the certain operating radius of needs, cause normally using box spanner to be dismantled with fastening the bolt in narrow location such as corners or nut, so workmen uses open-end wrench or double offset ring spanner to dismantle with fastening the bolt in narrow location such as corners or nut.Therefore, can dismantle and fastening box spanner the bolt in narrow location such as corners or nut in the urgent need to a kind of.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of simple in structure, easy to use, can dismantle and fastening bendable box spanner the bolt in narrow location such as corners or nut.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of bendable box spanner, comprise handle, connecting rod, spring, collet head, it is characterized in that: one end of described connecting rod is fixedly connected with the middle part of handle is vertical, the other end is fixedly connected with one end of spring, and the other end of spring is fixedly connected with the top of collet head.
The diameter of described connecting rod is greater than the diameter of described spring.
The diameter of described collet head is greater than the diameter of described spring.
Compared with prior art, the utlity model has following beneficial effect: simple in structure, easy to use, can dismantle and fastening the bolt in narrow location such as corners or nut, be conducive to improve dismounting and fastening bolt in narrow location such as corners or the operating efficiency of nut.
