The utility model has the advantages that: compared with the prior art, the utility model discloses an adjustable slot, arc draw-in groove and cut planar articulated shaft, the articulated department position of being convenient for is adjustable to realize that special-shaped spanner opening size is adjustable, application scenario greatly increased, application range enlarges, and equipment cost reduces, need not to carry more spanners, alleviates carrying tool weight, labour saving and time saving, adjusts convenient and fast, connects reliably stably, can not have not hard up problem.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of a hinge rod joint;
fig. 3 is a sectional view schematically showing the structure of the hinge shaft coupled to the wrench head.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example (b): as shown in fig. 1-3, an opening-adjustable special-shaped wrench structure, including wrench head 1 and wrench arm 2, wrench head 1 is handstand hook portion structure, the lower extreme is rotatably connected to 2 tip of wrench arm through hinge bar 3, 2 upper end of wrench arm is provided with curved sawtooth portion, be provided with bar adjustment tank 4 on the 3 junction of hinge bar wrench head 1, the length direction of bar adjustment tank 4 is the same along wrench head 1 length direction, arrange a plurality of arc draw-in grooves 5 that equal with 3 diameters of hinge bar on the 4 length direction of bar adjustment tank, 4 length direction symmetrical arrangement of the relative bar adjustment tank of arc draw-in groove 5, hinge bar 3 is provided with two planes 6 of symmetry, two planes 6 interval is less than bar adjustment tank 4 width, bar adjustment tank 4 both ends adopt nut 7 to lock.
Preferably, be provided with torsional spring 8 between above-mentioned spanner head 1 and spanner arm 2, torsional spring 8 cup joints on articulated mast 3, can let have the resilience force all the time between spanner arm and spanner head with its closed opening, plays the anticreep effect, and special-shaped spanner can be more reliable with being twisted nut or screw interlock in the operation process moreover.
Preferably, the tail end of the wrench arm 2 is connected with an adapter 9 with a hexagonal outer shape, so that the ratchet wrench can be conveniently connected, and the direction can be adjusted.
Articulated shaft position adjustment theory of use: and loosening the nut, rotating the hinged shaft of the cutting plane, removing the arc-shaped clamping groove at the proper position of the two cutting planes when the two cutting planes are separated from the arc-shaped clamping groove and can be arranged in the strip-shaped adjusting groove, rotating the hinged shaft, rotating the cutting planes to the length direction of the vertical strip-shaped adjusting groove, locking the nut, and finishing the position adjustment.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention, therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
