Abstract
A kind of spanner, it is primarily of spanner and brace arm composition, it is characterized in that described brace arm is formed with being connected by rotating shaft between spanner, and described brace arm to be spun by screw thread by epimere brace arm and hypomere brace arm and forms; Described epimere brace arm is formed for being provided with externally threaded round bar, and hypomere brace arm is an end closure and inwardly arranges female pipe at the other end to form; The upper end of described epimere brace arm is provided with end face connecting groove, and the link of spanner is plugged in described connecting groove to connect with horizontal rotating shaft and forms; It is simple that it has structure, and easy to use, flexibility and reliability, adjustment force arm lengths can regulate again the features such as the angle between spanner and the arm of force.
Description
Technical field
The utility model relates to a kind of spanner, belong to a kind of follow-on Practical spanner.
Background technology
Existing spanner, the arm of force of its structure composition is all fixing, and is also fixing and uncontrollable between the spanner of spanner and the arm of force, thus causes cannot using spanner in some occasions or in use making troubles.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of that carry out improveing on prior art basis, adjustment force arm lengths can regulate angle between spanner and the arm of force, spanner that in use can be more flexible and convenient.
The purpose of this utility model has been come by following technical solution, it is primarily of spanner and brace arm composition, described brace arm is formed with being connected by rotating shaft between spanner, and described brace arm to be spun by screw thread by epimere brace arm and hypomere brace arm and forms.
Described epimere brace arm is formed for being provided with externally threaded round bar, and hypomere brace arm is an end closure and inwardly arranges female pipe at the other end to form; The upper end of described epimere brace arm is provided with end face connecting groove, and the link of spanner is plugged in described connecting groove to connect with horizontal rotating shaft and forms.
The utility model improves the one of prior art, and it is simple that it has structure, and easy to use, flexibility and reliability, adjustment force arm lengths can regulate again the features such as the angle between spanner and the arm of force.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, spanner described in the utility model, it forms primarily of spanner 1 and brace arm 2, described brace arm 2 is formed with being connected by rotating shaft 3 between spanner 1, and described brace arm 2 to be spun by screw thread by epimere brace arm 21 and hypomere brace arm 22 and forms.
Described epimere brace arm 21 is for being provided with the round bar formation of external screw thread 23, and hypomere brace arm 22 is an end closure and is inwardly provided with the pipe formation of internal thread 24 at the other end; The upper end of described epimere brace arm 21 is provided with end face connecting groove 25, and the link 11 of spanner 1 is plugged in described connecting groove 25 to connect with horizontal rotating shaft 3 and forms.
The brace arm of spanner is designed to telescopic adjustable tap wrench arm by the utility model, wherein use internal thread respectively and externally threadedly mutually to spin, therefore the length that just easily can be changed brace arm by turn screw thread can be needed according to scene when using spanner, the arm of force of spanner is made to have controllability, flexibility
The utility model has flexibility to make the spanner of spanner, designs a turning cylinder, by this turning cylinder, can regulate the angle between spanner and brace arm between spanner and brace arm, and not 180 constant all the time.
