Further, the feeding sleeve blind and the feeding bolt are fixed through a pin and a corresponding cylindrical pin hole.
Further, the connecting rod is a square column as a whole.
Further, the shell is of a square cylinder structure and is surrounded by three faces, namely one face is provided with an opening.
Further, one end of the connecting block is provided with a grinding wheel and fixed by screws.
Furthermore, the circular truncated cone in the middle of the feeding bolt is arranged in the shell to limit.
Furthermore, knurling is processed on the outer circular surface of the feeding sleeve.
The technical effects of the utility model are that: the utility model has the advantages of, rust cleaning device with adjustable design has used the screw precession to move back the structure soon, only needs the rotatory feed sleeve alright adjust the emery wheel position under the condition of a centre gripping, and the feed amount is adjustable in succession, and is easy and simple to handle.
The connecting block 1 is right-handed thread with the position screw thread that feeds of feeding bolt 3, and the nut 4 that plays the positioning action is left-handed thread with the 3 connecting portion of feeding bolt, realizes the locking effect after nut 4 screws the location, has effectively prevented that emery wheel vibrations from leading to the screw thread not hard up to roll back, makes the rust cleaning process have stability.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 2, the utility model discloses a emery wheel rust cleaning device with adjustable mainly comprises connecting rod 1, casing 2, feed bolt 3, nut 4, feed sleeve 5.
The whole connecting block 1 is a long square column, a grinding wheel assembling hole is machined in the side face of one end of the connecting block, and a right-hand thread blind hole is machined in the bottom face of the other end of the connecting block.
The shell 2 is of a three-side surrounding structure, one side of the shell is bottomless, the bottom surface of the other side of the shell is a U-shaped opening, and the shape and the size of the cross section of the inner cavity are the same as those of the bottom surface of the connecting block 1.
One end of the feed bolt 3 is provided with a right-handed external thread which is matched and connected with a right-handed threaded hole of the connecting rod 1; the other end of the connecting shaft close to the bottom part is an optical axis, a cylindrical pin hole is processed, and the light receiving shaft part is a section of left-handed thread; the middle part (left side of the left-handed thread) is a circular boss.
