In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: comprises a main frame; a threaded rod is arranged in the middle of the main frame; the main frame is connected with the threaded rod through threads; straight notches are respectively formed in two sides of the main frame, and stepped rods are arranged in the straight notches; the step rod is connected with the straight notch through a fastening nut; a bearing supporting plate is arranged at one end of the stair rod, which is far away from the main frame; the step rod is connected with the bearing supporting plate through a bolt; the two side bearing plates are connected through two symmetrically arranged threaded connecting rods; and step grooves are formed in the inner sides of the two bearing supporting plates.
Further optimize this technical scheme, threaded connecting rod is close to bearing supporting plate both sides and is provided with stop nut.
Further optimize this technical scheme, be provided with the spring between two bearing plate on the threaded connection rod.
Further optimizing the technical scheme, a cross rod is arranged at one end, far away from the main frame, of the threaded rod; the cross rod and the threaded rod are welded.
Compared with the prior art, the utility model has the advantages of it is following: 1. the stepped grooves are formed in the bearing supporting plate, so that bearings of different types can have larger contact stress areas with the bearing supporting plate, and the bearings are uniformly stressed and are not easy to damage; 2. the spring is arranged between the two bearing supporting plates, so that the parts can be stressed uniformly and can move smoothly in the process of adjusting the tool, and the parts are not easy to clamp.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The specific implementation mode is as follows: as shown in connection with fig. 1-3, comprises a main frame 1; a threaded rod 2 is arranged in the middle of the main frame 1; the main frame 1 is in threaded connection with the threaded rod 2; two sides of the main frame 1 are respectively provided with a straight notch 101, and a step rod 3 is arranged in the straight notch 101; the stepped rod 3 is connected with the straight notch 101 through a fastening nut 301; a bearing supporting plate 4 is arranged at one end of the step rod 3 far away from the main frame 1; the step rod 3 is connected with the bearing supporting plate 4 through a bolt; the two bearing supporting plates 4 are connected through two symmetrically arranged threaded connecting rods 5; stepped grooves 401 are formed in the opposite inner sides of the two bearing supporting plates 4; the two sides of the threaded connecting rod 5 close to the bearing supporting plate 4 are provided with limit nuts 501; a spring 6 is arranged between the two bearing supporting plates 4 on the threaded connecting rod 5; a cross rod 7 is arranged at one end of the threaded rod 2 far away from the main frame; the cross rod 7 and the threaded rod 2 are welded.
When the bearing is used, in the first step, the shaft is connected with the bearing, the shaft and the inner ring of the bearing are sleeved together and are generally in interference fit (the diameter of the shaft is slightly larger than that of the inner ring of the bearing). Therefore, the inner ring of the bearing is tightly sleeved on the shaft to form a whole, and the trouble is caused when the bearing is required to be disassembled.
