(1) this scheme is provided with fixation nut at the support column surface of towing pintle body, and fixation nut is the hexagon, setting through fixation nut, the spanner that facilitates the use is installed or is dismantled the towing pintle, this towing pintle is provided with the roller that can roll in the inside of towing pintle ring again, when connecting the haulage rope and pulling the vehicle, because the setting of roller, can reduce the wearing and tearing of haulage rope, prevent haulage rope burr until the fracture, have the effect of guaranteeing to pull safety and haulage rope life, do benefit to the use.

(2) The right-hand member of support column is provided with connecting bolt, and connecting bolt has installs the tow hook body on the vehicle, carries out towed effect to damaging the vehicle.

(3) The external fixed surface of support column has cup jointed fixation nut, through fixation nut's setting, has the effect that facilitates the use spanner and carries out being connected towing pintle body and vehicle.

(4) The upper and lower both ends symmetric connection of roller has the baffle, baffle and roller sliding connection, and the baffle has the effect of restriction haulage rope position for the haulage rope can only be on the roller surface, can not have the phenomenon of haulage rope joint in roller and pivot junction gap.

(5) The cross-sectional area of the baffle is larger than that of the roller, and the traction rope can be effectively limited on the surface of the roller due to the arrangement of the baffle with a larger area.
