Right end sidewalls are provided with regulating tank, and the bottom face right inward groove of the connecting pole has a T-type accommodating groove, the T-type accommodating groove with
Regulating tank or so is connected to, and the inner cavity sliding of the regulating tank is connected with sliding shoe, and the left end of the sliding shoe extends to T-type storage
Slot inner cavity, and it is fixedly welded with adjusting rod on the left of bottom face, the bottom end of the adjusting rod is rotatablely equipped with limit buckle, the hook
Bottom end tip consubstantiality be extended with crotch to the right, the limit buckle is adapted to crotch.
Preferably, the top end face center of the connecting pole is fixedly welded with connection retaining ring, the connection retaining ring bottom face with
The top end face of hook welds.
Preferably, the regulating tank is respectively 10mm apart from connecting pole upper and lower ends face.
Preferably, the right end of the sliding shoe is fixedly welded with handle.
Preferably, the adjusting rod outer wall is socketed with buffer spring, and is respectively positioned on T-type accommodating groove inner cavity.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention links up with for a kind of crane arm, convenient for envelope
The notch for closing hook prevents, in operation, there is the phenomenon that becoming less severe or slipping, reduces danger coefficient, simple and practical.
