During assembly, the two top fastening pieces 130 are respectively screwed into the corresponding locking holes 112 in two opposite directions, in the process of screwing the top fastening pieces 130 into the locking holes 112, the tensioning action of the tensioner 110 is realized through the locking bolts 121, the stress rationality of the locking bolts 121 is greatly improved, when the top fastening pieces 130 are screwed into the positions which are abutted against the locking bolts 121, the top fastening pieces 130 cannot be screwed into the locking holes 112 continuously due to the fact that the locking bolts 121 abut against the top fastening pieces 130, when the top fastening pieces 130 are screwed continuously, the tensioner 110 can move in the opposite direction of the screwing direction of the top fastening pieces 130, therefore, the two tensioner 110 can be drawn close to each other and pull the two adjacent chain units 213 to each other, the first chain 211 is tensioned due to the tension action, the connecting holes 111 are arranged into strip-shaped holes, the moving range of the tensioner 110 can be limited, and the locking bolts 121 are fixed on the paint conveying tank 260, the tensioner 110 can move within the length of the coupling hole 111 with reference to the locking bolt 121; when the first chain 211 is tensioned, the two locking bolts 121 are respectively tightened to lock the two tensioners 110, so that the position of the tensioners 110 is fixed, at this time, the tensioners 110 cannot move, and the tensioning action is completed; during the process of screwing the two locking bolts 121 out of the locking holes 112, the two tensioners 110 move away from each other to release the two adjacent chain units 213 from each other, and the first chain 211 is loosened. When the chain unit 213 of the transferring member 210 pulls the tensioner 110, the pulling force is transmitted to the top tightening member 130 of the tensioner 110, and since the top tightening member 130 abuts against the connecting assembly 120, the pressing force, not the pulling force, applied to the top tightening member 130 is excellent for the force applied to the top tightening member 130.

In summary, the anti-loosening mechanism 100 provided by the present application prevents the connecting member 120 from loosening by abutting the fastening member 130 against the connecting member 120, so that the connecting member 120 can fix the tensioner 110 to a heavy object more firmly.
