Description

Multifunctional wrench

The utility model relates to a kind of spanner.

Known spanner can be tightened or looser a bolt and nut, but function singleness can not be dismantled pipe fitting, cut-out bar, can not stretching wire rod or coiling.In real work, in the time of need carrying out work such as fastening, cut-out, backguy, must the band upper ejector lever, dental forceps, hacksaw, drawing machine, multiple instrument such as cutting machine is made troubles to construction, influences operating efficiency.

The purpose of this utility model is that a kind of multifunctional wrench will be provided, and it both can be tightened or looser a bolt and nut, can dismantle pipe fitting again, cut off bar, can also stretching wire rod or coiling.

The purpose of this utility model is achieved in that this wrench comprises handle, and the front end of handle connects cranks arm, and there is tooth the inboard of cranking arm, the front end coupling of cranking arm.

Described annex is cutter, and blade one side is lonely shape.

Described annex can also be a clamping limb.

Described annex can also be the saw cutter, and saw cutter tooth side is lonely shape.

The described inboard all right branch sleeve assembly of cranking arm, sleeve assembly are connected by screw by brace cranks arm, and brace connects little axle, is with the sleeve composition on the little axle.

Described annex can also be a thread drawing mechanism, and thread drawing mechanism is by an end connecting line of axle wheel, and the other end of axle connects ratchet, and the middle part of axle connects bracing frame, and bracing frame connects two ratchets, the ratchet composition that matches with ratchet.

The utility model both can be tightened or looser a bolt and nut, can dismantle pipe fitting again, cut off bar, can also stretching wire rod or coiling.Can also eliminate rust, can also kerf.Even get rusty, the bald head bolt and nut also can dismantle easily.Simple in structure, cost is low, and is easy to carry, can be used as pincers worker, pipeliner, the use of electrician's instrument.
