Description
Technical field
The utility model relates to a kind of spanner, and specifically a kind of Extensible portable box spanner, belongs to machine tool technical field.
Background technology
Box spanner is made up of the collet head 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.In production and life, the structure of widely used box spanner is all generally fixing at present, dismounting and fastening cannot be carried out to the bolt or nut that are in different depth position by the length of regulating sleeve spanner connecting rod, the box spanner often needing workmen to carry multiple different length specification just can complete dismounting and fasteningly be in the bolt of different depth position or the task of nut, and can not regulate due to the length of existing box spanner connecting rod, be not easy to workmen carry box spanner and carry out operation, so not only increase use cost, and increase the labour intensity of workmen, be unfavorable for increasing work efficiency.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of structure simple, easy to use, and can carry out dismantling and fastening Extensible portable box spanner to the bolt or nut that are in different depth position by the length of regulating connecting rod.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of Extensible portable box spanner, comprise handle, connecting rod, guide rail, spring, studs, locking nut, slide bar, through hole, chamfering, 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 both sides of connecting rod are provided with guide rail, spring and slide bar is provided with in connecting rod, the upper end of slide bar is provided with through hole, studs is provided with in through hole, studs is provided with locking nut, the lower end of slide bar is provided with chamfering, slide bar is connected by the top of the chamfering with collet head that are arranged on lower end.
The length of described studs is greater than the width of described connecting rod.
The width of described guide rail is greater than the diameter of described studs.
The length of described connecting rod is greater than the drift of described spring.
The length of described connecting rod is greater than the length of described guide rail.
Compared with prior art, the utility model has following beneficial effect: structure is simple, easy to use, can the length of regulating sleeve spanner connecting rod in a big way, thus can dismantle and the fastening bolt or the nut that are in different depth position, effectively reduce the quantity of the box spanner carried required for workmen, and pass through the length of regulating sleeve spanner connecting rod, convenient construction personnel carry box spanner and carry out work, so not only use cost can be reduced, and the labour intensity of workmen can be reduced, be conducive to increasing work efficiency.
