The utility model discloses a wrench with a sleeve, which comprises a sleeve, a connecting rod, a fixing sleeve and a wrench rod. The sleeve is provided with a first fixing portion, and the fixing sleeve is provided with a second fixing portion, and one end of the connecting rod The sleeve is fixed on the first fixing portion, and the other end is fixed on the second fixing portion. The wrench rod is disposed through the fixing sleeve. The fixing sleeve is provided with a through hole through which the wrench rod can pass, and the sleeve is provided with a groove and a groove. There are six top plates matched with the nut, and the top plate is connected with a fixing plate. The fixing plate is provided with two screws, and the sleeve is provided with a fixing nut matched with the two screws, and the fixing plate is symmetrically disposed on both sides. In the rib plate of the fixed top plate, the rib plate is provided with a flexible supporting pad which cooperates with the inner wall of the groove, and the fixing sleeve is provided with a fixing screw for fixing the wrench rod, and the positioning rod is symmetrically arranged on both sides of the wrench rod.

When the wrench is used, the length can be adjusted. When the nut is rotated, the rotating force is large, and the working surface is in surface contact, and no slip phenomenon occurs. At present, the rotation of the workpiece is mainly realized by a wrench or a wrench with a sleeve, and the rotation is performed after the fitting, but in actual long-term use, it is not difficult to find that the cooperation of the workpiece and the socket wrench is often linearly matched at the beginning. The reason is that the size of the workpiece must be just slightly smaller than the inner hole size of the sleeve. Therefore, when the sleeve rotates, the edge of the workpiece is the first to contact the sleeve. This contact is The linear contact will only slowly become part of the surface contact after the edge is worn. The rotation of the sleeve structure has a great damage to the workpiece or the sleeve, resulting in damage to the workpiece or the sleeve. The service life of the existing wrench with a sleeve is fixed when the nut is rotated, and the position of the nut is different. When the nut is installed deep, the length is required to be used. Long wrenches, but there are currently no wrenches with adjustable lengths. Basically, they are used to carry different lengths of wrenches to meet the needs of the work.

The technical problem to be solved by the utility model is to provide a simple structure, convenient use and installation, simple operation, adjustable length when the wrench is used, large rotating force when rotating the nut, face contact with the working surface, and no slip phenomenon. A wrench with a sleeve that has a low cost, a wide range of applications, a long service life, and a safe and reliable function. a wrench with a sleeve, comprising a sleeve, a connecting rod, a fixing sleeve and a wrench rod, wherein the sleeve is provided with a first fixing portion, and the fixing sleeve is provided with a second fixing portion, the connecting rod One end is fixed on the first fixing portion, and the other end is fixed on the second fixing portion. The wrench rod is disposed through the fixing sleeve, and the fixing sleeve is provided with a through hole through which the wrench rod can pass. a groove is provided, wherein the groove is provided with six top plates matched with a nut, and the top plate is connected with a fixing plate, and the fixing plate is provided with two screws, and the sleeve is provided with a seat。

The two screws are matched with the fixing nut, and the fixing plate is symmetrically provided with ribs for fixing the top plate, and the rib plate is provided with a flexible supporting pad that cooperates with the inner wall of the groove, and the fixing sleeve is provided a fixing screw for fixing a wrench rod, wherein the wrench rod is symmetrically disposed with a positioning plate, and the wrench rod is provided with a screw hole matched with the fixing screw, and the connecting rod is connected by the first connecting rod and the first Two connecting rods are composed. As a preferred technical solution, the ends of the first connecting rod and the second connecting rod are respectively provided with matching grooves, and the tail portions of the first connecting rod and the second connecting rod are respectively provided with positioning rods, and the a positioning rod at the tail end of the connecting rod cooperates with a matching groove provided at the end of the second connecting rod, and the positioning rod is disposed in the engaging groove of the end portion of the first connecting rod, and the first connecting rod extends to the first In the fixing portion, the first fixing portion is provided with a first positioning bolt for fixing the first connecting rod, and the first positioning bolt is disposed through the first fixing portion, the first connecting rod and the block.
