The invention provides a plug uninstalling and fastening
wrench for railway locomotive maintenance. The plug uninstalling and fastening
wrench comprises two connecting rods, one end of the connecting rods are clamp
handle parts, the other ends of the connecting rods are clamp
head parts, the number of the connecting rods is two, the two connecting rods are hinged through a hinge shaft, the clamp
head parts have arc-shaped structures, and anti-skid units are arranged on the inner sides of the arc-shaped structures and used for preventing the clamp
head parts and a shell of the to-be-uninstalled
aviation plug from moving relatively, front-end buckles are arranged at the ends, away from one end of the clamp
handle part, of the clamp head parts, and the front-end buckle is used for being inserted into a socket of an inner core of a to-be-uninstalled-installed
aviation plug. The plug uninstalling and fastening
wrench for the railway locomotive maintenance has the beneficial effects that the plug uninstalling and fastening wrench for the railway locomotive maintenance is simple in force application, more labor is saved compared with manual operation, and the wrench is suitable for a narrow space, and the clamping surface is provided with the insection part made of a hard plastic material, so that the
contact friction force is increased on one hand, and on the other hand, the damage to the plug during use is reduced relative to a
metal contact surface.
