Description
Technical field
This utility model and a kind of spanner technical field, particularly relate to a kind of band chain wrench.
Background technology
Spanner is a kind of instrument for the turn of the screw, existing spanner is generally divided into the figurate solid wrench of tool and the internally installed ratchet spanner having ratchet, solid wrench the most once can only pull screw due to stiff when pulling screw, the poor efficiency of the turn of the screw, and although ratchet spanner inside is provided with ratchet, ratchet spanner when pulling screw be also pull screw, only during spanner return, speed is a little fast, also not having the raising efficiency of essence, this utility model well solves and existing there is technical problem.
Summary of the invention
This utility model provides a kind of band chain wrench, which solves existing spanner and uses the most inconvenient, and during existing spanner return, speed is a little fast, and also do not have essence puies forward high efficiency situation shortcoming.
A kind of band chain wrench of the present utility model, including a spanner barre, it is characterized in that being provided with positioning through hole in the middle part of described spanner barre, upper one end of described spanner barre is provided with a manhole, it is set with spanner pullover in described manhole, described spanner is pullover in T shape, its termination is pullover, middle part is provided with axle sleeve, can location firm with spanner barre, its rear portion is provided with gear ring, described spanner handle lower end is fitted with drive shaft in being provided with through hole, it is set with drive sprocket in described drive shaft, described drive shaft outer tip end connects crank, described drive sprocket and gear ring are connected transmission by chain.
As preferably, described crank is connected with drive shaft by pin, and described crank can fold, and during folding, the handle of crank passes positioning through hole, makes drive shaft locked.
A kind of band chain wrench of the present utility model, in use, when drive shaft is in locking state, pullover with drive shaft chain drive is also at locking state, it is possible to twist, by spanner barre, the screw rod that comparison is tight, when the screw that stubborn comparison is loose, crank is converted into deployed condition, by rotating crank, the pullover rotation of band wrench, screw fast unscrewing or screw.
