[0033] In a possible embodiment, a second nut 34 is provided on a side of the first nut 33 away from the end cover 11 , and the second nut 34 is used in conjunction with the screw rod 32 .

[0034] In a possible embodiment, a connecting plate 210 is fixedly provided at the upper end of the movable plate 23, a plurality of evenly distributed through grooves 220 are opened in the end cover 11, one end of the connecting plate 210 is slidably set in the through groove 220, and a shift block 230 is fixedly provided at the end of the connecting plate 210 away from the movable plate 23.

[0035] In a possible embodiment, guide rods 4 are slidably inserted in the connecting plates 210, and both ends of the guide rods 4 are fixedly mounted on the inner wall of the mounting block 2;

[0036] Specifically, by providing the guide rod 4, the connection plate 210 is limited, so that the connection plate 210 can move stably.

[0037] In a possible embodiment, the outside of the moving plate 23 is fixedly provided with a mirror-distributed stabilizing block 41, and a stabilizing rod 42 is slidably inserted in the stabilizing block 41, and both ends of the stabilizing rod 42 are fixedly installed with the inner wall of the mounting block 2;

[0038] Specifically, by providing the stabilizing block 41 and the stabilizing rod 42 , the movable plate 23 is reinforced and limited, so that the movable plate 23 can move stably.

[0039] Working principle:

[0040] First, when disassembling the end cover 11, rotate the first nut 33 and the second nut 34 to disengage the first nut 33 and the second nut 34 from the screw rod 32, then rotate the screw rod 32 to remove the screw rod 32 from the first thread groove 3 and the second thread groove 31, and drive the connecting plate 210 to move in the opposite direction by shifting the shift block 230, and the connecting plate 210 drives the moving plate 23 to move in the opposite direction, and the moving plate 23 drives the clamping block 24 to move in the opposite direction. When the clamping block 24 is in the process of moving in the opposite direction, the spring 22 is compressed and deformed under the action of the moving force of the moving plate 23, and when one end of the clamping block 24 completely leaves the clamping groove 25, the mounting block 2 is removed from the mounting groove 21, and the disassembly between the end cover 11 and the bearing box 1 is completed;

[0041] Subsequently, when the end cover 11 and the bearing box 1 need to be installed, the shifting block 230 is driven to move toward each other through the connecting plate 210, and the moving plate 23 drives the clamping block 24 to move toward each other. When the clamping block 24 moves toward each other, the spring 22 is compressed and deformed. When the clamping block 24 completely enters the mounting block 2, the mounting block 2 is placed in the mounting groove 21. Subsequently, the shifting force of the shifting block 230 is removed, and the spring 22 is reset. Under the action of the resetting elastic force of 22, the movable plate 23 moves in the reverse direction, and the movable plate 23 drives the clamping block 24 to move in the reverse direction. When one end of the clamping block 24 completely enters the clamping groove 25, one end of the screw rod 32 is completely screwed into the first thread groove 3 and the second thread groove 31. Then, the first nut 33 and the second nut 34 are rotated. When one end of the screw rod 32 completely enters the threaded holes in the first nut 33 and the second nut 34, the installation between the end cover 11 and the bearing box 1 is completed.

[0042] The installation between the end cover 11 and the bearing box 1 is completed by first fixing the mounting block 2 in the mounting groove 21, and the end cover 11 is prevented from shaking when the end cover 11 and the bearing box 1 are installed and disassembled using the screw rod 32, the first nut 33, and the second nut 34, so as to facilitate use.

[0043] The above embodiments are only used to illustrate the technical solution of the present application, but not to limit it. The present application is not limited to the exact structure described above and illustrated in the accompanying drawings, and it cannot be determined that the specific implementation of the present application is limited to these descriptions.
