Description
Technical field
The utility model relates to a kind of bolt fastening instrument, is specifically related to a kind of multi-functional special key, belongs to mechanical fastening techniques field.
Background technology
Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is shaped with clamp holder portion in the one or both ends of shank usually, in order to apply external force, twists bolt or nut.Only need threadingly direction of rotation to apply external force at shank during use, just can twist bolt or nut.
On existing hardware market, conventional spanner has two kinds, and one is single-end spanner, namely only has one end to have screwed hole, and another kind is double (end) wrench, namely all has screwed hole end to end.The range of application of these two kinds of spanners is all very extensive, if but have two screws to lean on very near, just need use two spanners to fix and rotary screw, not only use inconvenience, also need standby many spanner.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of easy to use, multi-functional special key of reducing costs.
According to the technical scheme that the utility model provides, multi-functional special key, comprises handle, back-up wrench head and Flexible spanner at hand; Described handle tip arranges back-up wrench head and Flexible spanner at hand respectively; Described back-up wrench head is fixedly connected with handle is vertical; Flexible spanner is flexibly connected with handle at hand.
Described back-up wrench head and the first end of monkey wrench are equipped with the screw hole of a holding screw.The bottom of described handle has a hook hole.Described Flexible spanner can rotate at hand, and the anglec of rotation is 45-180 °.
The beneficial effects of the utility model: the multi-functional special key that the utility model provides not only can meet the instructions for use of single-end spanner, can also meet the screw fastening requirement of some special angle, easy to use, reduce cost.Meanwhile, the setting of hook hole also can make this holding tools very convenient.
