Scaffold Spanners Manufacturing Method

The utility model relates to a scaffolding tool for building, which relates to scaffold spanners for sale. Scaffolding has become an indispensable stand in modern architecture.  The special wrench for the installation of scaffolding is a special wrench with a multi-angle bore that can be used to catch four-corner or hex nuts or bolts. When the wrench is used, the wrench cannot be forced until it is rotated by a certain angle.  At this point, the wrench must be removed from the bolt (or nut), turn an angle, then put on the bolt (or nut), and then turn the wrench, and then repeatedly turn until the bolt (or nut) is tightened (or  Loosen until). It is inconvenient to use because the wrench needs to be taken out and put on and off intermittently.  And with a little careless, the wrench is easy to fall off from the height, and is not safe.  And the work efficiency is low, so it is not ideal.

The purpose of the utility model is to design the convenient, safe and effective scaffold spanners for sale. 

The object of the present invention is to realize the design of the scaffold spanners for sale by a jacket with a wrench, an inner sleeve with a 2N multiple (N is an integer), and an inner sleeve and a cover plate.  The inside of the jacket has ratchets and balls.  It cooperates with the pawl provided on the inner sleeve. When the trigger drives the outer sleeve to rotate in a certain direction, the inner sleeve rotates in this direction together with its stuck bolt.  After rotating a certain angle, the lever and its outer sleeve rotate in the opposite direction to return the trigger to its original position.  At this time, the inner sleeve and the stuck bolt (or nut) do not move due to the action of the ratchet pawl.  Therefore, it is not necessary to remove the wrench from the stuck bolt (or nut), and then tighten the bolt (or nut) as long as the wrench is turned back and forth. When you want to loosen the bolt (or nut), simply snap the opposite side of the wrench to the bolt (or nut) and turn the wrench back and forth.  There is also no need to remove the wrench and re-attach it. It can be seen that the scaffold spanners for sale have the advantages of convenient operation, safety, high work efficiency and the like.  Especially in terms of ergonomics, it can more than double the existing special wrench.
