Description
Technical field
The utility model relates to a kind of spanner, and specifically a kind of bending dual-purpose type box spanner, belongs to machine tool technical field.
Background technology
Box spanner is made up of the sleeve of multiple band hexagon ring or 12 corner apertures and the multiple component such as handle and connecting rod, be specially adapted to dismantle and fastening residing for the bolt of the very narrow or very depths of caving in, space or nut.
Often need to use box spanner to carry out dismounting and fastening to bolt or nut in machine work.Because the structure of current widely used box spanner in production and life is all generally fixing, certain operating radius is needed when the existing box spanner of use to carry out dismounting and be fastening to bolt or nut, cause normally using box spanner to carry out dismounting and fastening to the bolt or nut that are in the narrow location such as corner, so workmen uses open-end wrench or double offset ring spanner to carry out dismounting and fastening to the bolt or nut that are in the narrow location such as corner.Therefore, dismantle and fastening box spanner in the urgent need to a kind of can carrying out the bolt or nut being in the narrow location such as corner.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of structure simple, easy to use, can carry out dismantling and fastening bending dual-purpose type box spanner the bolt or nut being in the narrow location such as corner.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of bending dual-purpose type box spanner, comprise handle, connecting rod, check lock lever, spring, collet head, trip bolt, tapped through hole, 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, the other end of spring is fixedly connected with the top of collet head, the outside of connecting rod is provided with check lock lever, the upper end of check lock lever is provided with tapped through hole, is provided with trip bolt in tapped through hole.
The length of described connecting rod is greater than the length of described check lock lever.
The upper end of described check lock lever is provided with tapped through hole, and object coordinates trip bolt fixing and locking bar, prevents check lock lever from loosening or coming off.
The length of described check lock lever is greater than the drift of described spring.
The diameter of described connecting rod is greater than the diameter of described spring.
The diameter at described collet head top is greater than the diameter of described spring.
Compared with prior art, the utility model has following beneficial effect: structure is simple, easy to use, can by will the spring bending between connecting rod and collet head be arranged on thus realize carrying out dismounting and fastening to the bolt or nut that are in the narrow location such as corner, be conducive to raising and dismantle and be fasteningly in the bolt of the narrow location such as corner or the operating efficiency of nut.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in figures 1 and 3, a kind of bending dual-purpose type box spanner, comprise handle 1, connecting rod 2, check lock lever 3, spring 4, collet head 5, trip bolt 6, tapped through hole 7, it is characterized in that: one end of described connecting rod 2 is fixedly connected with the middle part of handle 1 is vertical, the other end is fixedly connected with one end of spring 4, and the other end of spring 4 is fixedly connected with the top of collet head 5, and the outside of connecting rod 2 is provided with check lock lever 3, the upper end of check lock lever 3 is provided with tapped through hole 7, is provided with trip bolt 6 in tapped through hole 7.
The length of described connecting rod 2 is greater than the length of described check lock lever 3.
The upper end of described check lock lever 3 is provided with tapped through hole 7, and object coordinates trip bolt 6 fixing and locking bar 3, prevents check lock lever 3 from loosening or coming off.
The length of described check lock lever 3 is greater than the drift of described spring 4.
The diameter of described connecting rod 2 is greater than the diameter of described spring 4.
The diameter at described collet head 5 top is greater than the diameter of described spring 4.
As shown in Figure 1, when need to the bolt or nut that are in the narrow location such as corner carry out dismounting and fastening time, first unscrew trip bolt 6, then check lock lever 3 is stretched into along connecting rod 2, screw trip bolt 6 simultaneously and get final product fixing and locking bar 3, finally collet head 5 is aimed at and need to be disassembled and fastening bolt or nut, lateral pressure is applied by spring 4 bending to handle 1, be disassembled by needs is inserted in collet head 5 with fastening bolt or nut simultaneously, turning handle 1 can carry out dismounting and fastening to bolt or nut, thus realize carrying out dismantling and fastening object to the bolt or nut that are in the narrow location such as corner.
As shown in Figure 2, when do not need to the bolt or nut that are in the narrow location such as corner carry out dismounting and fastening time, first unscrew trip bolt 6, then check lock lever 3 is stretched out along connecting rod 2 and the top of collet head 5 is inserted in check lock lever 3, screw trip bolt 6 simultaneously and get final product fixing and locking bar 3, now applying lateral pressure to handle 1 just can not spring 4 bending, and finally being aimed at by collet head 5 needs to be disassembled with fastening bolt or nut and turning handle 1 can carry out dismounting and fastening to bolt or nut.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
