In order to solve the technical problems, the utility model adopts the following technical scheme:
a small-sized bearing quick dismounting tool comprises a gripping part, a connecting part, a supporting part and a hook part; the connecting part comprises a first screw rod, the tail part of the first screw rod is arranged to be conical, the head part of the first screw rod is fixed with a first nut, and a first through hole penetrating through the first screw rod is formed in the first nut; the gripping part comprises a second screw rod penetrating through the first through hole and provided with a smooth section in the middle, and the tail end of the second screw rod is provided with a threaded section and is provided with a second nut in a matching way; the supporting part comprises a third nut matched with the first screw rod and studs respectively fixed on two sides of the third nut; the two hook parts are arranged, each hook part comprises a fourth nut matched with the stud and a hook rod fixedly arranged at the lower end of the fourth nut, the tail end of the hook rod is provided with a wedge-shaped hook, and the wedge-shaped hooks of the two hook parts are oppositely arranged.
The technical scheme of the utility model is further improved as follows: the number of the second nuts is two.
The technical scheme of the utility model is further improved as follows: the stud is a full-thread stud.
The technical scheme of the utility model is further improved as follows: the diameter of the second screw rod is 1/2 of the diameter of the first screw rod.
By adopting the technical scheme, the utility model has the following technical progress:
the small bearing is pulled down and disassembled by gripping the gripping part by hand by hanging the hook part on the small bearing, the small bearing is simple in structure and is also applicable to small bearings with narrow disassembly positions; meanwhile, the force is uniformly transmitted to two sides when the force is applied, so that the small bearing can be conveniently detached; the support part can be knocked to assist the disassembly of the small-sized bearing when necessary, so that the damage to the small-sized bearing caused by direct knocking is avoided.
