Description

The portable multi-purpose spanner

Affiliated technical field

The utility model relates to a kind of improvement of tool wrench, and it can be operated the nut of multiple dimensions, can realize practicality, versatility, portable in the portable multi-purpose spanner of one.

Background technology

At present, existing every open-end wrench is operated the nut of two kinds of fixed dimensions only, the position, intermediate portion is only limited to the effect of handle all the time, never carries out any improvement.Many users are in order to operate the nut of plurality of specifications size easily, and just necessary purchase is many spanner of different size, has not only increased spending, also relatively take up room in collection, and it is just more numerous and diverse to take on-the-spot use to as need.The utility model carries out corresponding improvement to existing spanner, under the prerequisite that does not influence handle and spanner mass action, can operate the nut of plurality of specifications size, makes it improve service efficiency.

Summary of the invention

For this reason, technical problem to be solved in the utility model is open-end wrench is improved, and makes its nut that can operate more different specification sizes, to reach portability, versatility and practicality.

The technical scheme that its technical problem that solves the utility model adopts is: for realizing above-mentioned utility model purpose, the utility model is pulled in the mouth again the mouth of pulling that design has respectively increased by two place's different sizes with the two ends of open-end wrench, and has increased the built-in plum blossom in three places in the design of mid-handle position and pull mouth.The utility model be make spanner integral body not the reason work of respectively pulling mouthful produce phenomenons such as flexural deformation or fracture, in improvement, consider structure and stressing conditions that each position is different, designed the mouth of pulling of corresponding specification respectively, and spanner integral body improved, make it reach the multiduty while in operation, improve practicality of the present utility model.

The beneficial effects of the utility model are: because the utility model is provided with the plurality of specifications size, can satisfy the operation to the different specification size nut, embody multipurpose and portability; Described portable multi-purpose spanner itself is durable in use, easy to use, when reducing the conventional spanner production cost, has improved the utilization rate of resource, has embodied practicality.
