The invention relates to a sleeving machine, in particular to a gasket sleeving machine for a bolt. The technical problem is how to arrange the gasket sleeving machine for the bolt, and the gasket sleeving machine is simple to operate, can carry out sleeving quickly and has high working efficiency. The gasket sleeving machine for the bolt comprises a frame body, supporting legs and the like, wherein supporting legs are arranged on the left side and the right side of the bottom of the frame body. According to the gasket sleeving machine, a contact block knocks down the bolt and a gasket throughthe matching of a swing block and a n-type rod, and the bolt can also fall into a feeding pipe through the matching of a knocking block and a special-shaped groove, so that the workload of an operator is reduced; and meanwhile, a movable plate can be driven to move rightwards while a first gear rotates through the matching of a straight pore plate and a roller, so that the device is more convenient to use and the gasket in a storage barrel is more stable through the matching of a fifth spring and a pressing block.
