Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1-2, the utility model discloses a novel telescopic wrench, including casing 14 and a plurality of adjustable leaf 15 of pulling of locating 14 one end of casing, still including the telescopic machanism who locates casing 14, telescopic machanism connects a plurality of adjustable leaf 15 of pulling, telescopic machanism is used for controlling a plurality of adjustable leaf 15 of pulling and stretches out the length of casing 14 to this adapts to the bolt of different specifications.
The telescopic mechanism comprises a threaded rod 11 and a positioning nut 13, the positioning nut 13 is arranged inside a shell 14, a channel for the threaded rod 11 to move is arranged in the shell 14, the threaded rod 11 is in threaded connection with the positioning nut 13, and one end of the threaded rod 11 is connected with a plurality of movable pull blades 15. The threaded rod 11 is screwed, the threaded rod 11 moves in the shell 14 through the positioning nut 13, and therefore the movable pulling blade 15 is pulled, and the purpose that the movable pulling blade 15 stretches into the shell 14 is achieved.
In order that the movable blades 15 do not rotate when the threaded rod 11 is screwed, one end of the threaded rod 11 is provided with an annular clamping groove 16, and the annular clamping groove 16 is movably connected with a plurality of movable blades 15.
For better screwing of the threaded rod 11, the threaded rod 11 is also provided with a knob 10.
In order to make the spanner twist the time atress more stable, the utility model discloses a flexible spanner still is equipped with lock nut 12, and lock nut 12 locates the 14 outsides of casing, and lock nut 12 threaded connection threaded rod 11 has adjusted and has implemented locking through lock nut 12 after the 15 length of activity board leaf. One end of the shell 14 is provided with a plurality of holes 17 at equal intervals on the circumference, and the holes 17 are used for the movable blade 15 to extend out of the shell 14 and also have the function of positioning the movable blade 15.
In order to provide better force for the user during twisting, the housing 14 is a T-shaped housing having two torsion portions to facilitate the application of force.
According to the utility model discloses a flexible spanner scheme, the number of the leaf 15 is pulled to the activity can be set to four, six or twelve etc. as required, forms spanners such as four corners, hexagonal, or twelve angles, and the quantity in hole 17 is unanimous with the quantity of the leaf 15 is pulled in the activity simultaneously. As shown in fig. 3, which is a schematic view of a hexagonal wrench, the adjustable wrench blades 15 are equidistantly disposed around the threaded rod 11.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
