As preferably, described locating hole is positive six corner angle holes, coordinates the minimum angles that extension bar is rotated to reach 60 ° with extension bar termination, rotates flexibly, easy to adjust.

As preferably, described locating hole is positive 12 corner angle holes, coordinates the minimum angles that extension bar is rotated to reach 30 ° with extension bar termination, and adaptability is wider.

As preferably, described extension bar is two.

As preferably, the pin rod of described alignment pin is positive six prisms, pin rod tail end is provided with a through hole, and described through hole is inserted with lock pin, and alignment pin coordinates with locating hole connecting hole and through hole, can determine minimum rotation angle by the polygon prism angle of locating hole, regulate the angle between extension bar and spanner and handle and extension bar, avoid better the barrier encountered in the middle of use, make spanner can be used for the workplace of winding complex, lock pin can guarantee alignment pin firm plug, can not come off.

The beneficial effects of the utility model are: the shank that the spanner shank of original linearity is had to multiple parts instead and is flexibly connected and is serpentine configuration, all adjusting angles mutually of the connecting portion of each parts, the various obstacles of encountering when avoiding using, have greatly promoted use occasion and the scope of spanner.
