When the user opens the control center 21 to control the drive chamber 3 to again assist the adjusting piece 35 to be attached to the gate 50 to complete the closing step, the rotary drive assembly 31 is opened to drive the rotating rod of the bottom side to rotate, the rotating rod of the bottom side rotates to drive the first meshing roller 32 to rotate, the first meshing roller 32 rotates to drive the second meshing roller 33 to rotate through the rotating rod of the top side, the second meshing roller 33 rotates to drive the two first pressure plates 330 to rotate, the two first pressure plates 330 rotate to drive the two second pressure plates 34 to rotate through the two chains 36 respectively, the two second pressure plates 34 rotate to drive the adjusting piece 35 to rotate until the adjusting piece 35 is attached to the gate 50, at this time, the universal circuit breaker is in the closing state, when the user needs to manually operate the universal circuit breaker to open, only needs to control the rotary drive assembly 31 to drive the rotating rod of the bottom side to reverse rotation, so as to drive the adjusting piece 35 to reverse rotation and not to be attached to the gate 50, so as to complete it, in the above steps, the rotation of the second pressure plate 34 drives the two rotating arms 39 of the top side to rotate, the rotating arm 39 of the top side rotates to drive the rotating arm 39 of the bottom side to rotate through the telescopic plate 390, the rotating arm 39 of the bottom side rotates to drive the first elastic piece 37 to stretch or reset the elastic deformation, in the above steps, the number of teeth of the second pressure plate 34 is greater than that of the first pressure plate 330, that is, the first pressure plate 330 rotates several turns to only drive the second pressure plate 34 to rotate one turn, the above steps are the operation steps of the universal circuit breaker clutch mechanism of the large equipment in real life, and the subsequent will not be described in detail; Please refer toFigures 1 to 10 Further in the above description, the telescopic rod 40 is provided with two, which are respectively slidingly connected inside the two slide rails 380, the top of the telescopic rod 40 is sleeved with a through rod 41, the through rod 41 penetrates and extends to the inside of the storage chamber 4, the extension of the through rod 41 is fixedly connected with a piston plate 410, the two storage chambers 4 are fixedly connected with a delivery pipe 42 at one end close to the symmetry plane thereof, the other end of the delivery pipe 42 penetrates to the inside of the drive chamber 3, the connection between the delivery pipe 42 and the storage chamber 4 is fixedly connected with a first one-way valve; In the above step, the movement of the base plate 38 drives the telescopic rod 40 to move, since the telescopic rod 40 can rotate and slide at a certain angle in the slide rail 380, and the top rotating arm 39 and the bottom rotating arm 39 are sleeved by the telescopic plate 390, that is, the slide rail 380 and the telescopic plate 390 can limit the movement mode of the top rotating arm 39, the bottom rotating arm 39, and the base plate 38 when the top rotating arm 39 and the bottom rotating arm 39 rotate and drive the base plate 38 to move, and the movement of the base plate 38 drives the telescopic rod 40 to move, so that the telescopic rod 40 can only move up and down in a straight line under the driving of the base plate 38. When the universal circuit breaker changes from the closed state to the open state, the base plate 38 moves upward to drive the telescopic rod 40 to move upward, the telescopic rod 40 moves deep into the inside of the through rod 41, and when it reaches the deepest part of the through rod 41, it abuts against and pushes the through rod 41 to move upward, the movement of the through rod 41 drives the piston plate 410 to move in the storage chamber 4, the telescopic rod 40 and the through rod 41 can limit the movement distance of the piston plate 410 in the storage chamber 4, so as to avoid the over-lubrication of the clutch mechanism in the drive chamber 3 caused by the spraying of a large amount of lubricating oil at one time, the movement of the piston plate 410 increases the air pressure in the storage chamber 4 and transmits part of the lubricating oil to the drive chamber 3 through the delivery pipe 42, at this time, the drive chamber 3 obtains this part of the lubricating oil and can lubricate a series of components related to closing and opening, and the excess lubricating oil will drip through these components to the bottom inner wall of the drive chamber 3 and be collected, the second one-way valve is used to prevent the lubricating oil from being sprayed from the extraction pipe 43, so as to improve the maintenance effect of the lifting device and facilitate the use of the user; Please refer to Figures 1 to 10 Further in the above description, the extraction pipe 43 is provided with two, which are respectively fixedly connected at the rear end surfaces of the two storage chambers 4, the other ends of the two extraction pipes 43 are fixedly connected at the rear end bottom side of the drive chamber 3, the connection between the extraction pipe 43 and the storage chamber 4 is fixedly connected with a second one-way valve; When the universal circuit breaker is converted from the open state to the closed state, the series of components inside the driving chamber 3 are lubricated by the lubricating oil and can operate normally. As previously mentioned, the pad 38 can drive the telescopic rod 40 to move downward at this time. The movement of the telescopic rod 40 drives the piston plate 410 to move downward in the storage chamber 4 through the through rod 41, so that the air pressure inside the storage chamber 4 decreases. The lubricating oil gathered on the inner wall of the bottom side of the driving chamber 3 can be transported into the storage chamber 4 under the suction of the suction pipe 43. The first one-way valve is used to prevent the lubricating oil from flowing back. The lubricating oil lubricates the first meshing roller 32, the second meshing roller 33, and the chain 36. The lubricating oil on the surface of the chain 36 is lubricated through the meshing movement of the chain 36 with the first pressure plate 330 and the second pressure plate 34. The device can lubricate the engagement and disengagement mechanism involved in the closing and opening. The driving chamber 3 is arranged to wrap the structure involved in the closing and opening to avoid dust and debris from adhering to the surface of each component, thereby causing the components to jam. The driving chamber 3 can also prevent the recovered lubricating oil from contacting dust, thereby preventing the lubricating oil in the storage chamber 4 from being contaminated when it is recovered into the storage chamber 4, improving the maintenance effect of the device, and facilitating user use. Please refer to Figures 1 to 10 Further in the above description, the collecting chamber 360 is fixedly connected inside the driving chamber 3. The extension parts of the two delivery pipes 42 are fixedly connected at the left and right sides of the collecting chamber 360, respectively. The bottom side of the collecting chamber 360 is provided with a through hole. The left and right sides of the collecting chamber 360 are fixedly connected with two shunt pipes 361, respectively. The other end of the shunt pipe 361 is fixedly connected with a sleeve 362. The chain 36 is sleeved inside the sleeve 362. The front end and the rear end of the sleeve 362 are fixedly connected with a touch mouth, respectively. The inside of the sleeve 362 is provided with two balls 363, which are rotatably connected inside the sleeve 362 through the touch mouth. When the lubricating oil is delivered into the collecting chamber through the delivery pipe 42 in the above step, the through hole at the bottom of the collecting chamber can deliver the lubricating oil to the first meshing roller 32 and the second meshing roller 33 for lubrication. The arrangement of the shunt pipe 361 allows part of the lubricating oil to be delivered to the sleeve 362. When the chain 36 is driven to rotate by the meshing movement of the first pressure plate 330 and the second pressure plate 34, the rotation of the chain 36 drives the balls 363 inside the sleeve 362 to rotate. The rotation of the balls 363 applies part of the lubricating oil to the surface of the chain 36. On the one hand, the arrangement of the balls 363 avoids the excessive lubrication of the lubricating oil on the surface of the chain 36. The balls 363 can block the lubricating oil inside the sleeve 362 when they are not rolling. On the other hand, the arrangement of the balls 363 can center and limit the chain 36, avoiding the dislocation of the chain 36 when the universal circuit breaker is subjected to external force, thereby facilitating user use. Please refer to Figures 1 to 10Further in the foregoing description, the top side inner wall of the storage chamber 4 is fixedly connected with two second elastic members 44, the bottom of the two elastic members is fixedly connected with a buffer plate 45, and the buffer plate 45 is slidingly connected in the interior of the storage chamber 4; The second elastic member 44 is in a compressed state initially, and the two shielding plates 47 shield the air holes. The second elastic member 44 and the buffer plate 45 are arranged to tightly compact the lubricating oil, so as to reduce the situation that the remaining lubricating oil has a movable space due to the consumption of the lubricating oil and the reduction of the total amount of the lubricating oil, and air bubbles are easily generated by shaking; Please refer to Figures 1 to 10 Further in the foregoing description, the left and right side inner walls of the buffer plate 45 are fixedly connected with linear drive assemblies 46, the linear drive assemblies 46 are arranged as electric push rods, the end output ends of the linear drive assemblies 46 close to the symmetry planes are fixedly connected with shielding plates 47, and the interior of the buffer plate 45 is provided with air holes; When the extraction pipe 43 extracts the collected lubricating oil, part of the air is also extracted into the storage chamber 4. The air is easy to cause the air to be preferentially transported from the conveying pipe 42 when the lubricating oil is transported next time, so as to cause the total amount of the lubricating oil sprayed from the conveying pipe 42 to be reduced. When the total amount of the lubricating oil in the storage chamber 4 is reduced and the universal circuit breaker is transformed from the opening to the closing, the second elastic member 44 is released from the compressed state, and the elastic force generated thereby acts on the buffer plate 45 to make the buffer plate 45 move downward. In this process, the control center 21 is used to open the linear drive assemblies 46, the linear drive assemblies 46 drive the shielding plates 47 to move to make the shielding plates 47 separate from the air holes. At this time, the air in the storage chamber 4 can be discharged to the interior top side of the storage chamber 4 through the air holes. When the buffer plate 45 continuously moves downward and the amount of the lubricating oil is discharged from the air holes, the control center 21 is used to open the linear drive assemblies 46 to reset the shielding plates 47. At the same time, the user can discharge the air on the top side of the buffer plate 45 through the external pipeline at the shell 2. Therefore, the device can discharge the air while recycling the lubricating oil, avoid the air mixed into the lubricating oil to cause the total amount of the lubricating oil to be reduced next time, improve the maintenance effect of the device, and facilitate the user to use; Please refer to Figures 1 to 10 Further in the foregoing description, the front end surface of the shell 2 is fixedly connected with a visible plate 20, the visible plate 20 is arranged as a transparent material, and the front end top side of the shell 2 is fixedly connected with a control center 21; The arrangement of the visible plate 20 makes the user be able to view the interior of the universal circuit breaker through the shell 2.
