Without the action of external force, the elastic body 54 elastically connects the buckle rod 52 and makes the buckle rod 52 and the plug-in column 4 maintain an axial parallel connection, such as image 3 As shown, the buckle rod 52 and the plug post 4 are in a state where only the elastic body 54 is elastically connected. There are end rings 336 around the outer end of the pull-out ring sleeve 3; there are two synchronous clamping mechanisms 8, and both the end ring 336 and the connecting ring 61 are equipped with one synchronous Clamping mechanism 8; the synchronous clamping mechanism 8 includes a guide cylinder 82, a guide rod 83, an arc-shaped clamping plate 81, a positioning rod 85, an adjusting column 86, a drive screw 84; the end ring 336 and A guide tube 82 is installed on the upper and lower sides of the connecting ring 61; a guide rod 83 is slidably inserted into the guide tube 82; the outer end of the guide rod 83 is connected to an arc-shaped clamping plate 81; The arc-shaped clamping plate 81 is clamped and pressed against the outer surface of the stern tube 1; the rear inner end of the arc-shaped clamping plate 81 is respectively installed with a drive screw 84; the end ring 336 A positioning rod 85 is respectively installed on the middle and rear side of the connecting ring 61; the ends of the positioning rod 85 are respectively rotatably clamped to an adjusting column 86; the side of the adjusting rod 86 is rotatably clamped to the end of the positioning rod 85 , The upper and lower ends of the adjusting column 86 are provided with threaded driving grooves; the threaded driving grooves are threaded to connect the driving screw 84 at the inner end of the rear side of the arc-shaped clamping plate 81; the rotation of the adjusting column 86 drives the up and down The drive screw 84 and the arc clamping plate 81 at both ends move relatively. In the present invention, a ring-shaped clamping groove can be arranged on the side of the adjusting column, and an arc-shaped clamping block is arranged at the end of the positioning rod 85, so that the clamping groove of the adjusting column is rotatably clamped on the arc-shaped clamping block.

[0022] Such as Figure 1 to 5 As shown, it is further preferred that the axial length of the buckle groove 31 is greater than the axial length of the buckle block 53, where the axial direction refers to the axial direction of the entire bearing 2, which can facilitate the buckle block 53 to buckle. In the buckle groove 31, and leave space for the detachment of the buckle block 53 from the buckle groove 31. Further, it also includes a lever-retracting mechanism 7; the lever-retracting mechanism 7 includes a wire drawing 75, a sliding block 74, a clamping rod 73, a driving stud 72, and a driving rod 71; the inner middle of the inner end of the plug-in column 4 There is a drive 41 cavity; the upper and lower sides of the outside of the drive cavity 41 are respectively provided with sliding grooves 42; the inner circumference of the drive 41 cavity is provided with a threaded ring 43; the drive stud 72 is screwed and connected On the threaded ring surface 43 of the driving cavity 41; one end of the clamping rod 73 is fixed to one end of the driving stud 72, and the other end of the clamping rod 73 rotates to clamp the sliding block 74; the upper and lower sides of the sliding block 74 They are slidably connected to the sliding groove 42 by sliding teeth 741; one end of the sliding block 74 is connected to a drawing wire 75 on the upper and lower sides respectively; one end of the drawing wire 75 is connected to the sliding block 74, and the other end is connected to the buckle The inner side of the block 53; the other end of the driving stud 72 is equipped with a driving rod 71; one end of the driving rod 71 is fixed to the other end of the driving stud 72, and the other end of the driving rod extends to the outside of the outer end of the plug column 4. Furthermore, one end of the sliding block 74 is provided with a connecting plate 76 on the upper and lower sides respectively; one end of the drawing 75 is connected to the connecting plate 76. Furthermore, the outer side of the buckle block 53 is provided with an abutting inclined surface 531; the inner side of one end of the pulling ring sleeve 3 is provided with a tapered abutting ring 32. Further, a pull ring 33 is installed at the outer end of the pull ring sleeve 3 respectively.

[0023] The present invention adds a synchronous clamping mechanism 8, through the adjustment column 86 at one end of the positioning rod 85 for clamping rotation, so that the rotation of the adjustment column 86 drives the upper and lower ends of the drive screw 84 to expand and contract, so that the drive screw 84 drives the arc clamp The holding plate 81 performs synchronous relative movement to adjust the clamping distance of the two arc-shaped holding plates 81, so as to adapt to stern tubes of different pipe diameters; the present invention designs a cleverly structured stern shaft bearing disassembly structure. 4 When the inner end is inserted into the bearing 2, the buckle rod 52 and the buckle block 53 are driven to move to the inside of the inner end of the pull ring sleeve 3. The buckle block 52 is first pressed by the inner end surface of the pull ring sleeve 3 to make the The buckle block 53 and the buckle rod 52 rotate inwardly around the rotating shaft 51, and then the buckle block 53 and the buckle rod 52 continue to move to the inside of the pull-out ring sleeve 3, when the snap-in block 53 reaches the pull-out ring sleeve 3 When the buckle groove 31 is formed, the buckle block 53 is pressed into the buckle groove 31 by the elastic pressing of the elastic body 54, so that the pull-out ring sleeve 3 and the plug-in column 4 are locked inside the bearing 2, and then the limit The position screw 61 rotates and abuts on the upper and lower sides of the other end surface of the bearing 2. At this time, the pulling ring sleeve 3 is directly pulled out, and the bearing 2 and the plug post 4 can be pulled out directly. The structure of the present invention is cleverly designed and used convenient. The present invention adds a rod retracting mechanism 7, which is a structure for disassembling the pulling ring sleeve 3 and the plug-in column 4 after the bearing 2 is removed. By rotating the driving rod 71, the driving rod 71 drives the driving screw The column 72 rotates. When the driving stud 72 rotates and moves, the sliding block 74 is driven to move in the driving cavity 41 by the clamping rod 73, so that the sliding block 74 pulls the drawing wire 75, and the drawing 75 removes the locking block 53 from the locking groove 31 is rotated and pulled out, so that the pull ring sleeve 3 and the plug post 4 are separated.
