The driving shaft passes through the arc-shaped guide groove on the guide plate and is inserted into the long groove on the disc and passes through the circular hole at the inner end of the moving rod. The driving shaft is axially limited by the first and second retaining rings on the driving shaft which are respectively located on the inner side of the guide plate and the outer side of the disc. There is a retaining ring groove outside the long groove on the outer side of the disc. The connecting rod, connecting shaft, connecting sleeve, driving shaft, and moving rod are at least six groups and are evenly distributed along the circumference of the sleeve, guide plate, and disc.

[0007] The barrel maintenance tool of the utility model is placed in the barrel when in use, and the end part of the central axis and the sleeve are left outside the barrel. The operator holds the end part of the central axis and the sleeve with his left and right hands respectively, and then rotates relatively, that is, the sleeve rotates on the central axis, and the connecting rod, the connecting shaft and the driving shaft rotate around the central axis. Since the driving shaft is inserted into the guide groove on the guide plate, the guide plate and the central axis are relatively fixed, so the driving shaft slides in the guide groove, and each driving shaft moves radially outward of the circumference. The moving rod moves radially outward along the disc driven by the driving shaft, and the arc plate moves accordingly, so that the overall diameter of the multiple arc plates surrounded by the outer side of the disc is enlarged, and a rag is covered on the arc plate. When the rag leans against the inner wall of the barrel, the tool can be pulled back and forth to clean and maintain the barrel. When the inner diameter of the barrel changes, the operator adjusts the rotation angle of the sleeve on the central axis relatively according to the hand feeling to ensure that the arc plate pushes the rag against the inner wall of the barrel. After the end, the sleeve is rotated in the opposite direction to retract the arc plate and pull out the tool. The use of the tooling to maintain the barrel has the advantages of simple structure, time and labor saving, reduced labor intensity and improved work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] like Figures 1 to 4 As shown: the barrel maintenance tool of the utility model comprises a central shaft 1, the end of the central shaft 1 is fixedly connected to a circular plate-shaped guide plate 12 through a key 25, a disc 14 is mounted on the central shaft 1, and an inner bearing 21 and an end bearing 19 are respectively installed on both sides of the disc 14 on the central shaft 1 to ensure that the disc 14 can rotate relative to the central shaft 1. A moving rod 15 is inserted radially into the disc 14, and radial long grooves 23 are provided on both sides of the moving rod 15 on the disc 14, and an arc plate 13 is fixedly connected to the outer end of the moving rod 15. A circular hole is provided at the inner end of the moving rod 15.

[0013] A sleeve 2 is sleeved on the outside of the central shaft 1, one end of the connecting rod 4 is rotatably connected to the sleeve 2 through the first pin 3, the other end of the connecting rod 4 is rotatably connected to the connecting shaft 6 through the second pin 5, and the connecting shaft 6 is connected to the driving shaft 11 through the connecting sleeve 8. The driving shaft 11 passes through the arc guide groove 22 on the guide plate 12 and then is inserted into the long groove 23 on the disc 14 and passes through the circular hole at the inner end of the moving rod 15. The driving shaft 11 is axially limited by the first snap ring 10 and the second snap ring 17 on the driving shaft 11, which are respectively located on the inner side of the guide plate 12 and the outer side of the disc 14.
