Meanwhile, the pin shaft 400 can further fix the three wrenches, so that the reliability in use is improved.
In the preferred embodiment, the pin 400 is provided with a protrusion at one end, and the protrusion is used for limiting the pin 400. A magnet 500 is provided on the projection. When the combined multi-head wrench is not used, the combined multi-head wrench can be directly adsorbed on the wall surface such as an iron plate or the shell of machine equipment parts by utilizing the magnetism of the magnet 500, is convenient to idle and is easy to find when being used again.
In the preferred embodiment, the other end of the pin 400 is further provided with a nut 600, and the nut 600 is in threaded connection with the pin 400. The combined multi-head wrench can be further fixed by using the nut 600 to connect the pin 400. When a single wrench is needed to be used independently, the nut 600 is screwed out, the pin shaft 400 is taken out, and the single wrench can be taken out for use.
Compared with the prior art, the combined multi-head wrench is formed by embedding and combining three wrenches of different models through the notches which are matched with each other closely. The joint of the three wrenches is also provided with a pin shaft and a nut to further fix the combined multi-head wrench. Nut and round pin axle can be dismantled, and then three spanner can also be dismantled and use alone. And, still be provided with magnet at round pin axle one end, when not using, can adsorb on iron class metal, be convenient for deposit, conveniently look for.
