[0032] A lifting mechanism 2, which is located between the converter platform 1 and the movable cover body 6 and is used to lift the movable cover body 6; the lifting mechanism 2 includes two fixed plates fixed on one side of the converter platform 1 and a driving motor 21 fixed on the top of one of the fixed plates, a threaded rod 22 is installed between the two fixed plates, the threaded rod 22 is connected to the output end of the driving motor 21, and a moving block 23 is screwed on the outer wall of the threaded rod 22, the moving block 23 extends to the interior of the converter platform 1 and is connected to the movable cover body 6, and a moving groove for the moving block 23 to move is opened on one side of the converter platform 1.

[0033] The threaded rod 22 is driven to rotate by the driving motor 21, and the rotation of the threaded rod 22 drives the moving block 23 to move on its outer wall, and the movement of the moving block 23 drives the movable cover body 6 to move synchronously, thereby performing a lifting operation on the movable cover body 6.

[0034] Please refer to Figure 2 , Figure 3 and Figure 4 , a reinforcement mechanism 3, which is located between the movable sleeve body 6 and the converter platform 1 and is used to reinforce the movable sleeve body 6. The reinforcement mechanism 3 includes a sliding mechanism and a positioning mechanism. The sliding mechanism is located between the movable sleeve body 6 and the converter platform 1 and is used to prevent the movable sleeve body 6 from shifting during displacement. The positioning mechanism is located on both sides of the sliding mechanism and is used to position the sliding mechanism. The sliding mechanism includes reinforcement blocks 31 fixed on both sides of the movable sleeve body 6. A reinforcement groove 33 for sliding the reinforcement block 31 is provided inside the converter platform 1. The positioning mechanism includes an extension block 32 fixed on both sides of the reinforcement block 31. A groove body for sliding the extension block 32 is provided on both sides of the reinforcement groove 33. A fixing rod 34 is installed inside the groove body, and the fixing rod 34 is inserted into the extension block 32.

[0035] The up and down movement of the movable sleeve main body 6 drives the reinforcement block 31 to move, so that the reinforcement block 31 moves in the reinforcement groove 33, and the movement of the reinforcement block 31 drives the two extension blocks 32 to move, so that the two extension blocks 32 move on the outer wall of the fixed rod 34. The reinforcement groove 33 and the fixed rod 34 are set, so that the reinforcement block 31 can be effectively limited. By limiting the reinforcement block 31, the movable sleeve main body 6 is limited synchronously, thereby preventing the movable sleeve main body 6 from being offset during the movement.

[0036] Please also refer to Figure 1 , Figure 5 and Figure 6 A fixing mechanism 4 for fixing the reinforcement block 31 is provided between the reinforcement block 31 and the converter body 5, the fixing mechanism 4 includes a fixing seat 41 fixed to one side of the converter platform 1, a support seat 43 is fixed to one side of the converter platform 1, a support plate that contacts the bottom of the fixing seat 41 is installed on the top of the support seat 43, and a plug-in mechanism for plugging the reinforcement block 31 is provided between the support seat 43 and the reinforcement block 31, the plug-in mechanism includes a storage groove provided inside the fixing seat 41 and a fixing block 42 installed inside the storage groove, a slot for inserting the fixing block 42 is provided on one side of the reinforcement block 31, and the fixing block 42 is inserted into the fixing seat 41. Bumps 44 are fixed on both sides of the fixed block 42, and grooves for the sliding of the bumps 44 are opened on both sides of the storage groove, and a plurality of evenly distributed rollers 45 are installed at the bottom of the storage groove, and the tops of the plurality of rollers 45 cooperate with the bottom of the fixed block 42.

[0037] When the movable sleeve body 6 needs to be lifted, the control sleeve is first pulled to drive the movable rod 47 to move, and the movement of the movable rod 47 drives the fixed block 42 to move, and the movement of the fixed block 42 drives the spring 46 to contract, and the contraction of the spring 46 separates the fixed block 42 from the slot, and the separation of the fixed block 42 from the slot enables the reinforcement block 31 to move in the reinforcement slot 33;

[0038] When the movable sleeve body 6 does not need to be lifted and is at the top of the converter body 5, the control sleeve is released to reset the fixed block 42 through the elastic force of the spring 46. The fixed block 42 is reset to be plugged into the slot. The mutual plugging of the fixed block 42 and the slot can effectively fix the reinforcement block 31, thereby reducing the pressure on the converter body 5 caused by the movable sleeve body 6. The setting of the roller 45 makes the fixed block 42 smoother in the process of moving and will not get stuck easily. The mutual cooperation between the protrusion 44 and the slot cavity will prevent the fixed block 42 from being separated from the receiving slot in the process of moving.
