Abstract
The invention discloses a special wrench for an inner triangular bolt. The special wrench comprises a wrench body, a reversing disc and a foldable handle. An octahedral column model is designed at the upper end of the wrench body, and the lower end of the wrench body is designed to be a solid capable of coinciding with the inner triangular bolt. The reversing disc is internally provided with two adjacent half-octagon inner holes, opening parts communicate with each other, and a threaded hole is formed in the right end of the reversing disc and connected with a threaded part at the left end of the foldable handle in a threaded connection manner. A section of thread is arranged at the left end of the foldable handle and can be in threaded connection with the right end of the reversing disc. The right end of the foldable handle is designed into the form of a three-section foldable handle, the part at the rightmost end and the middle part can be completely folded into a whole, the part at the leftmost end and the middle part can be folded by 90 degrees to the maximum degree, and two rotation pivots are connected through a rivet. The special wrench has the beneficial effects of being simple in structure, easy and convenient to operate, high in work efficiency and the like. According to the special wrench, the tool is used for operating the inner triangular bolt, especially under the condition that large tightening and loosening force is needed, rotation in the clockwise direction and the anticlockwise direction can be easily finished, meanwhile, the force applying dead angle cannot be generated, and the special wrench is a novel practical invention convenient to use and efficient.
Description
Technical field
The present invention relates to the special spanner field on interior triangular bolt.
Background technology
The current special spanner field on interior triangular bolt, , special spanner spanner on most interior triangular bolts is when in use because environment is limited, cannot continuously be operated, sometimes have to that frequently spanner is taken down and rotated to an angle, and easily produce dead angle, so that fastening is very inconvenient with release bolt, sometimes rotation dead angle can also be produced, user has to itself attitude regulation to the position that cannot be exerted oneself, simultaneously, common wrench handle portion is generally shorter, user uses more laborious, easily fatigue is frequently used for a long time, greatly reduce production efficiency.
The content of the invention
The purpose of the present invention is to overcome the above not enough, there is provided a kind of spanner with commutation function.When using,Commutation board is connected with spanner,Then by wrench body and interior triangular bolt connection,Mutually agreed with the octagon column of wrench body upper end with half all directions hole in commutation board,Rotary spanner handle,Then it is capable of achieving the clamping and the operation unclamped to chuck,When continuous rotation is needed,The half octagonal opening direction in commutation board is only needed to separate handle with commutation board,Then handle opposite direction is rotated to an angle,Wrench body is set to agree with commutation board from newly,So avoid frequently to separate wrench body with interior triangular bolt and agree with,Change the connection by wrench body and commutation board,So as to the operation of continuous rotation can be completed,Due to agreeing with mode using octahedral,So most 45 ° of rotation can be such that wrench body agrees with again with handle,Can avoid producing dead angle of exerting oneself completely,User need not additionally adjust posture again when using,It is time saving and energy saving,While the present invention is provided with two and agrees with half all directions hole,When stepping up,Step up mouth using commutation board,During release,Use release mouth;Commutation board is designed using disc, is allowed to that larger operating physical force can be born when in use, is unlikely to deform, and is damaged；Handle portion uses the foldable stock of three-stage, when larger clamping force is needed, can be fully deployed and do boosting-rod and use, and bigger power can be produced when step up and unclamp, while greatling save workman's muscle power.
