[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 In this embodiment, a portable plugging removal device for a single-row ball slewing bearing comprises a single-row ball slewing bearing body and a plugging removal mechanism used in conjunction with the single-row ball slewing bearing body, wherein the single-row ball slewing bearing body comprises an inner ring 1, an outer ring 3, a cone pin 4 and a plug 5; a steel ball 2 is installed between the inner ring 1 and the outer ring 3, and is blocked by the plug 5 in the outer ring 3; the cone pin 4 is inserted into the pin hole of the plug 5, and when the single-row ball slewing bearing body needs to be disassembled, the cone pin 4 on the plug 5 is pulled out, and a screw hole is provided at the end of the plug 5; wherein the plugging removal mechanism is composed of a hexagon socket screw 6, a locking screw 6, and a screw hole. The shaft sleeve 7, the guide shaft 8, the impact sleeve 9 and the elastic retaining ring 10 for the hole are composed; the impact sleeve 9 is installed on the guide shaft 8, the elastic retaining ring 10 for the hole is installed at the rear end of the impact sleeve 9, the hexagon socket screw 6 is installed in the locking sleeve 7, the locking sleeve 7 is fastened to the left end of the guide shaft 8, and the locking sleeve 7 and the guide shaft 8 are fastened by threads; the plugging removal mechanism is assembled in the screw hole opened at the end of the plug 5 by the hexagon socket screw 6.
