[0029] The main shaft 1; the left and right ends of the main shaft 1 are fixedly installed with plug sleeves 2;

[0030] A fixing assembly is arranged inside the plug sleeve 2, and the fixing assembly includes a secondary shaft 3, a flange fork 1 4 is fixedly installed on the side facing the secondary shaft 3, and a flange fork 2 5 is arranged inside the flange fork 1 4; a fixing groove 9 is provided on the surface of the plug sleeve 2 and the secondary shaft 3, a fixing rod 10 is movably connected inside the fixing groove 9, a moving groove 11 is provided at the bottom end of the fixing rod 10, a limiting rod 12 is movably connected inside the moving groove 11, and a limiting block 13 is fixedly installed at the rear end of the limiting rod 12;

[0031] The positioning mechanism is arranged inside the plug sleeve 2.

[0032] The operator takes out the limit rod 12 and the limit block 13 from the inside of the movable groove 11, and then takes out the fixed rod 10 from the inside of the fixed groove 9 to cancel the limit on the secondary shaft 3. Then the secondary shaft 3 can be taken out from the inside of the plug-in sleeve 2, and then the flange fork 1 4 and the flange fork 2 5 can be maintained. After the maintenance is completed, the secondary shaft 3 can be reinserted into the inside of the plug-in sleeve 2, and then the secondary shaft 3 can be rotated to position it. Then the fixed rod 10 can be inserted into the inside of the fixed groove 9, and then the limit rod 12 and the limit block 13 are aligned, and the limit rod 12 and the limit block 13 are inserted into the inside of the movable groove 11, so that the limit block 13 passes through the movable groove 11, and then the limit rod 12 is rotated to cause the limit block 13 to be misaligned with the movable groove 11, so that the fixed rod 10 fixes the secondary shaft 3.

[0033] Wherein, the positioning mechanism includes a spring 6, a positioning block 7 and a positioning slot 8;

[0034] The spring 6 is movably connected to the interior of the plug sleeve 2 , the positioning block 7 is fixedly connected to a side opposite to the spring 6 , and the positioning groove 8 is opened on the surface of the secondary shaft 3 .

[0035] Through the design of the positioning mechanism, after the secondary shaft 3 is inserted into the connector sleeve 2, the spring 6 will be compressed, and then the secondary shaft 3 can be rotated. When the positioning groove 8 is aligned with the surface of the positioning block 7, the elastic force of the spring 6 can make the positioning block 7 enter the interior of the positioning groove 8, thereby completing the positioning. After the positioning is completed, the fixing grooves 9 on the surfaces of the connector sleeve 2 and the secondary shaft 3 will be aligned.

[0036] A sealing ring 15 is fixedly mounted on the surface of the secondary shaft 3 , and a sealing groove 14 is provided on the opposite side of the plug-in sleeve 2 .

[0037] Through the design of the sealing groove 14 and the sealing ring 15 , after the secondary shaft 3 enters the interior of the plug-in sleeve 2 , the sealing ring 15 will also enter the sealing groove 14 , thereby sealing the plug-in sleeve 2 to prevent dust and rainwater from entering the interior of the plug-in sleeve 2 .

[0038] Among them, it also includes a lubrication mechanism, which is arranged inside the flange fork 4, and the lubrication mechanism includes a lubrication box 16, a feed port 17 and a discharge port 20;

[0039] The lubrication box 16 is opened inside the flange fork 4 , the feed port 17 is fixedly connected to the top end of the flange fork 4 , and the discharge port 20 is opened at the bottom end of the lubrication box 16 .

[0040] Through the design of the lubrication mechanism, the lubricant can be poured from the feed port 17 into the lubrication box 16, and then the lubrication box 16 stores the lubricant. When lubrication is needed, the blocking mechanism is rotated to keep the blocking mechanism away from the inside of the discharge port 20. Then the lubricant will flow out from the inside of the discharge port 20, thereby lubricating the flange fork 25. After the lubrication is completed, the blocking mechanism can be reset to block the discharge port 20 to prevent the lubricant from flowing out from the inside of the discharge port 20.

[0041] A contact plate 19 is fixedly installed inside the lubrication box 16 , and the contact plate 19 is of a “triangle” design.

[0042] Through the design of the contact plate 19, after the lubricant enters the lubrication box 16, it will fall on the top of the contact plate 19. Because the contact plate 19 is triangular in design, the lubricant will gather at the lower end of the contact plate 19, thereby facilitating the lubricant to flow out from the inside of the discharge port 20.

[0043] The surface of the feed port 17 is provided with plugs 18 , and the number of the plugs 18 is four.

[0044] Through the design of the plug 18 , after the lubricant is added, the plug 18 can be put on the surface of the feed port 17 to prevent the lubricant from flowing out from the inside of the feed port 17 .

[0045] The invention also includes: a blocking mechanism, which is arranged inside the flange fork 1 4, and the blocking mechanism includes a moving groove 21, a rack 22, a gear 23 and a rotating rod 24;

[0046] The second moving groove 21 is opened inside the flange fork 1 4 , the rack 22 is movably connected inside the second moving groove 21 , the gear 23 is rotatably connected inside the flange fork 1 4 , and the rotating rod 24 is fixedly connected to the opposite side of the gear 23 .

[0047] Through the design of the blocking mechanism, when lubrication is needed, the rotating rod 24 can be rotated to drive the gear 23 to rotate. Because the gear 23 is meshed with the rack 22, the gear 23 drives the rack 22 to move on the surface of the movable groove 21, so that the rack 22 is away from the inside of the discharge port 20. Then the lubricant will pass through the discharge port 20 to lubricate the surface of the flange fork 25. After lubrication is completed, the rotating rod 24 can be rotated in the opposite direction to reset the rack 22, thereby blocking the discharge port 20.

[0048] The working principle and use process of this utility model:

[0049] First, when the operator needs to disassemble, he needs to rotate the limit block 13 to align the limit rod 12 with the movable groove 11, then the limit rod 12 can be pulled out from the inside of the movable groove 11, and the limit on the fixed rod 10 can be cancelled. Then the fixed rod 10 can be pulled out from the inside of the fixed groove 9, and then the secondary shaft 3 can be removed from the inside of the plug-in sleeve 2. Then the operator can maintain the flange fork 1 4 and the flange fork 2 5. After the maintenance is completed, the secondary shaft 3 can be reinserted into the inside of the plug-in sleeve 2. During the movement of the secondary shaft 3, it will contact the positioning block 7. , and then push the positioning block 7 to move. During the movement of the positioning block 7, the spring 6 will be compressed. After the secondary shaft 3 enters the interior of the plug-in sleeve 2, the secondary shaft 3 can be rotated. During the rotation process, when the positioning groove 8 is aligned with the surface of the positioning block 7, the elastic force of the spring 6 will make the positioning block 7 enter the interior of the positioning groove 8 to complete the positioning. Then the fixed groove 9 on the surface of the secondary shaft 3 and the fixed groove 9 on the surface of the plug-in sleeve 2 will overlap, and then the fixing rod 10 can be inserted into the interior of the fixing groove 9, and then the limit block 13 and the limit rod 12 are aligned with the movable groove 11, and then the limit rod 12 and the limit The stopper 13 is inserted into the moving groove 11 so that the stopper 13 passes through the moving groove 11. After passing through, the stopper rod 12 can be rotated to dislocate the stopper 13 and the moving groove 11, so that the fixing rod 10 fixes the plug sleeve 2 and the secondary shaft 3. When lubrication is required during the rotation of the flange fork 25, the plug 18 can be removed from the surface of the feed port 17, and then the lubricant can be poured from the feed port 17 into the lubrication box 16 so that the lubrication box 16 stores the lubricating oil. When lubrication is required, only the rotating rod 24 needs to be rotated to drive the rotating rod 24 to drive the lubricating oil to be stored in the lubrication box 16. The gear 23 rotates, and during the rotation process of the gear 23, it drives the rack 22 to move, so that the rack 22 is away from the inside of the discharge port 20, and then the lubricant will flow to the surface of the flange fork 25 through the discharge port 20, thereby lubricating the flange fork 25. After the lubrication is completed, the rotating rod 24 can be rotated in the opposite direction, so that the rotating rod 24 drives the gear 23 to rotate in the opposite direction, and the gear 23 drives the rack 22 to move in the opposite direction, so that the rack 22 moves to the inside of the discharge port 20, thereby blocking the discharge port 20 and preventing the lubricant inside the lubrication box 16 from flowing out, and finally completing the operation process.
