Description
The utility model relates to the tool technique leader, relates in particular to the Pipe wrench technical field.
Existing SW-B type gas pipe thread hinge spanner; adopt bolt die head and spanner frame two parts to form; in spanner frame circular hole, be provided with ratchet sleeve; during use the bolt die head is allocated in the spanner frame ratchet sleeve, carried out ream behind the jump ring circle folder position in the ratchet sleeve, because the jump ring clamping force is little; when EO takes out spanner; bolt die head regular meeting comes off from the ratchet sleeve of spanner frame suddenly voluntarily, often pounds and hurts sb.'s feelings, and is very dangerous during operation.
The purpose of this utility model is to provide a kind of above-mentioned defective that overcomes.Easy to operate, can not cause the safety corridor spanner of pounding the phenomenon of hurting sb.'s feelings because of the bolt die head comes off.
Now be described in detail the technical solution of the utility model:
Bolt die head, ratchet that the utility model comprises spanner frame, tommy bar, is used with the spanner frame, it also comprises a tight block, bolt die head cylindrical one end is provided with ratchet, spanner frame circular hole arc limit is provided with a tight block, propping up on the tight link stopper has a bayonet socket, and bayonet socket and its arc limit of spanner frame touching position of a tight block match.
The technical scheme that the utility model also can be taked is that a tight block mainly is made up of stage clip, steel ball, block, and by the pin location, block is provided with positioning pit, stage clip, steel ball, a positioning pit formation tightening position.
The utility model has the advantages that owing to be provided with ratchet structure at the first end of bolt die, ratchet can directly be stirred the bolt die head during operation.Owing to adopt a tight link stopper, tightly effective, when EO took out spanner, the bolt die head just can not come off easy to operate, flexible, safety.
