After the roll collar of the high-speed wire rod production line pre-finishing mill is used for a certain tonnage, the surface of a rolling groove is abraded and needs to be replaced. When the roll collar of the pre-finishing mill is replaced, the roll collar is fixed or loosened on a roll shaft by means of elastic deformation generated by the back-and-forth movement of a taper sleeve arranged on a roll collar cap under the action of hydraulic pressure or hydraulic pressure unloading of an inner cavity of the roll collar cap. The hydraulic beating and unloading of the inner cavity of the roll ring cap are completed by the combined action of a roll changing hydraulic trolley, a hydraulic oil pipe and a quick connector. Two quick male connectors are mounted on the roller ring cap and are used for replacing rollers and releasing pressure respectively. To allow pressure to build, the quick male connector must be connected to a quick female connector mounted on the tubing of the hydraulic trolley.

In order to protect the threads of the male connector, two pits and threaded holes are designed for the roller ring cap of the high-speed wire rod production line pre-finishing mill so that the quick male connector is installed on the pit threaded holes. However, due to the limitation of the structure of the roll collar cap, the distance between the concave pit and the male connector is small (generally less than 1.5 cm); meanwhile, two hexagon socket head cap bolts are arranged beside each pit and are used for loosening and tightening the inner plunger of the roller ring cap. This design causes operating personnel to only use two fingers to carry out the action of connecting nut screwing or becoming flexible on the quick female joint, and the palm back often causes the damage with hexagon socket head cap screw. When the connector is rusted, the connecting nut on the female connector is difficult to be connected with or separated from the thread line of the male connector by two fingers, so that the operation is very inconvenient, and the working efficiency is reduced.
