Abstract

The utility model relates to a fixed sleeve end monkey wrench composed of a handle and movable sleeve heads. The utility model is characterized in that the two ends of the handle of the wrench are connected with two movable sleeve heads through pin shafts. One of the movable sleeve heads is large, and the other one of the movable sleeve heads is small. The wrench ends at the two ends form an arc end face. The inner frames of the movable sleeve heads are unequal polygonal sleeves. The wrench is an ideal manual tightening tool and has the advantages of simple structure, easy application, low cost and multiple functions. One wrench can be applied to the work of tightening and loosening nut caps of various types and sizes, and the surfaces of the nut caps can not be damaged.

Description

Fixed sleeve end monkey wrench

The utility model belongs to a kind of fastened tools, a specifically a kind of fixedly running-on spanner alive that is used for the fastening bolt nut.

The spanner of selling on the China market has two kinds basically at present: a kind of is shfting wrench, it changes the size of pulling mouth by the screw adjustment, and the shortcoming of shfting wrench is that bayonet socket is not tight, and damages the nut surface easily, another kind is a socket wrench, its advantage is not fragile nut nut surface, and bayonet socket is tight, but shortcoming is a complex structure, cuff size is fixed, can not adjust, a kind of socket wrench of model only is suitable for a kind of nut nut of model, uses very inconvenient.

The purpose of this utility model provides a kind of simple in structure, and running-on can be adjusted, and is not easy to damage a fixedly running-on spanner alive of nut nut surface again.

Fixedly the work of a running-on spanner is made of with movable pullover handle, and it is pullover respectively to pacify an activity at the two ends of handle, and one of them is pullover bigger, and another is pullover less, is used for the nut nut of fastening different model size.Movable pullover inside casing is an inequilateral polygon, the curved end face of the driving end at handle two ends, the curved end of this driving end contact, tightens with the nut nut with movable pullover inequilateral polygon running-on, is used to tighten and unclamps nut nut, the purpose that realization is invented.

The utility model and existing shfting wrench, its advantage of socket wrench comparison are: simple in structure, implement easily, cheap, function is many, a spanner is applicable to multiple model, the nut nut of multiple size fastening and unclamp operation, and can not damage the surface of nut nut, be a kind of desirable manual fastened tools.
