Abstract
The invention relates to a multifunctional special wrench and belongs to the technical field of mechanical fixing. The multifunctional special wrench comprises a handle, a fixed wrench head and a movable wrench head, wherein the fixed wrench head and the movable wrench head are fixedly arranged at the top end of the handle, the fixed wrench head is perpendicularly fixedly connected with the handle, and the movable wrench head is movably connected with the handle. The multifunctional special wrench has the advantages that the multifunctional special wrench not only can meet usage requirements of a single-head wrench but also can meet fastening requirements of screws at special angles, thereby being convenient to use and lower in cost; meanwhile, the multifunctional special wrench is quite convenient and fast to store by being provided with a hook hole.
Description
Technical field
The present invention relates to a kind of bolt fastening instrument, be specifically related to a kind of multi-functional special key, belong 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 object of the invention is to overcome above-mentioned weak point, a kind of easy to use, multi-functional special key of reducing costs is provided.
According to technical scheme provided by the invention, 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 °.
Beneficial effect of the present invention: multi-functional special key provided by the invention 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, reduces cost.Meanwhile, the setting of hook hole also can make this holding tools very convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1, handle; 2, back-up wrench head; 3, screw hole; 4, Flexible spanner at hand; 5, hook hole.
Detailed description of the invention
As shown in Figure 1: multi-functional special key, handle 1, back-up wrench head 2 and Flexible spanner 4 is comprised at hand; Described handle 1 top arranges back-up wrench head 2 and Flexible spanner 4 respectively at hand; Described back-up wrench head 2 is fixedly connected with handle 1 is vertical; Flexible spanner 4 is flexibly connected with handle 1 at hand.
Back-up wrench head 2 and Flexible spanner at hand 4 one end are equipped with the screw hole 3 of a turn of the screw.The bottom of described handle 1 has a hook hole 5.Described Flexible spanner 4 can to rotate at hand, and the anglec of rotation is 45-180 °.
The present invention can meet general single-end spanner service condition; Meanwhile, run into part and make screw be difficult to fastening situation due to angle or position, only need by Flexible spanner of the present invention at hand 4 end rotation 45-180 °, just can carry out fastening after back-up wrench head 2 is fixing.
When equipment personnel do not need to use of the present invention, can be hung by hook hole 5.Easy to use, reduce costs.
