The inner wall of the push rod 34 is slidably connected to the outer wall of the threaded rod 31 through the limiting sleeve 35, and the top of the limiting sleeve 35 is fixedly connected to the bottom of the threaded rod 31. The outer wall of the push rod 34 is rotatably connected to the rotating wheel 36, and the outer wall of the rotating wheel 36 is fixedly connected to the scraper 37. The threaded position of the threaded rod 31 of the cleaning device 3 is screwed into the fixing sleeve 5 on the inner wall of the oil outlet pipe port 2, so that the cleaning device 3 is fixed on the oil outlet pipe port 2. When the oil inlet pipe body 1 and the oil outlet pipe port 2 are fitted together, the bottom of the push rod 34 will contact the filtering device 6 axial position, a support ring 62 is provided at the axial position of the filter device 6. Since the support ring 62 is fixed and applies thrust to the push rod 34, the push rod 34 subjected to the thrust will move axially along the threaded position of the threaded rod 31 under the limiting action of the limiting sleeve 35. At this time, the push rod 34 and the fixing ring 32 will squeeze the compression spring 33. Due to the slidable characteristic of the push rod 34, the cleaning device 3 has a certain fault tolerance during installation, and the cleaning device 3 does not need particularly precise positioning when it is disassembled and cleaned and then installed back.

[0018] The outer wall of the threaded rod 31 is threadedly connected to the inner wall of the fixed sleeve 5, the bottom of the push rod 34 is rotatably connected to the top of the filter device 6, the filter device 6 includes a filter screen 61, the bottom of the filter screen 61 is fixedly connected to a support ring 62, the outer wall of the support ring 62 is fixedly connected to the inner wall of the oil inlet pipe body 1, the top of the support ring 62 is rotatably connected to the bottom of the push rod 34, the bottom of the scraper 37 is in contact with the top of the filter screen 61, the filter device 6 blocks impurities from falling into the oil inlet pipe, and can be between the oil inlet pipe body 1 and the oil outlet pipe After the port 2 is connected, it blocks the impurities in the oil. After long-term use, the filter 61 in the filter device 6 will be blocked by impurities. The filter 61 is cleaned by setting the cleaning device 3, so that the filter 61 can continue to be used. When the oil starts to flow, due to the inclined setting of the scraper 37, the oil moves and pushes the scraper 37 to move. The scraper 37 rotates on the push rod 34 through the rotating wheel 36, and the bottom 37 of the scraper is in contact with the filter 61, thereby preventing impurities from continuously clogging the filter holes of the filter 61.

[0019] The positioning device 4 includes a movable sleeve 41, the top of the inner wall of the movable sleeve 41 is fixedly connected with a force storage spring 42, the bottom of the force storage spring 42 is fixedly connected to the outer wall of the oil outlet pipe port 2, the inner wall of the oil outlet pipe port 2 is slidably connected with a sliding bead 43 through a movable groove 44, and the movable groove 44 is opened in the wall of the oil outlet pipe port 2, the inner wall of the movable sleeve 41 is slidably connected with the outer wall of the oil outlet pipe port 2, and the inner wall of the movable sleeve 41 contacts the outer wall of the sliding bead 43. When the oil inlet pipe body 1 and the oil outlet pipe port 2 need to be connected, the movable sleeve 41 needs to be pressed downward before the connection, and at this time, the oil inlet pipe body 1 is pushed into the inner wall of the oil outlet pipe port 2. When the movable sleeve 41 is pressed downward, the force storage spring 42 is squeezed and starts to store force, and the movable sleeve 41 is pressed downward. The gap between the movable sleeve 41 and the oil outlet pipe port 2 will move to the position of the sliding bead 43, and the oil inlet pipe body 1 will push the sliding bead 43 into the gap between the movable sleeve 41 and the oil outlet pipe port 2 during the process of entering the oil outlet pipe port 2, so that the oil inlet pipe body 1 can be smoothly sent into the oil outlet pipe port 2. At the same time, the downward pressure on the movable sleeve 41 is released, so that the force storage spring 42 pushes the movable sleeve 41 to move upward, and the movable sleeve 41 pushes the sliding bead 43 to move to the groove position of the oil inlet pipe body 1, thereby completing the initial fixation of the oil inlet pipe body 1 and the oil outlet pipe port 2, and then the sliding threaded sleeve 7 is screwed into the threaded position of the oil outlet pipe port 2 to complete the secondary fixation, so that the connection between the oil inlet pipe body 1 and the oil outlet pipe port 2 is more stable.

[0020] Working principle:

[0021] When in use, a filter device 6 is arranged on the inner wall of the oil inlet pipe body 1 near the port to prevent impurities from falling into the oil inlet pipe. At the same time, impurities in the oil can be blocked after the oil inlet pipe body 1 and the oil outlet pipe port 2 are connected. After long-term use, the filter screen 61 in the filter device 6 will be blocked by impurities. The filter screen 61 is cleaned by setting a cleaning device 3, so that the filter screen 61 can continue to be used. The threaded position of the threaded rod 31 of the cleaning device 3 is screwed into the fixed sleeve 5 on the inner wall of the oil outlet pipe port 2, so that the cleaning device 3 is fixed on the oil outlet pipe port 2. When the oil inlet pipe body 1 and the oil outlet pipe port 2 are fitted with each other, the bottom of the push rod 34 will contact the axial position of the filter device 6. A support ring 62 is arranged at the axial position of the filter device 6. Since the support ring 62 is fixed in position and exerts a push on the push rod 34 The push rod 34 subjected to the thrust will move axially along the threaded position of the threaded rod 31 under the limiting action of the limiting sleeve 35. At this time, the push rod 34 and the fixing ring 32 will squeeze the compression spring 33. Due to the slidable characteristic of the push rod 34, the cleaning device 3 has a certain fault tolerance during installation. The cleaning device 3 does not need to be particularly precisely positioned when it is installed back after being disassembled and cleaned. At the same time, under the push of the reaction force generated by the compression spring 33 after being squeezed, the bottom of the push rod 34 is stably fitted on the top of the support ring 62. When the oil starts to flow, due to the inclined setting of the scraper 37, the oil moves and pushes the scraper 37 to move. The scraper 37 rotates on the push rod 34 through the rotating wheel 36, and the bottom 37 of the scraper is in contact with the filter screen 61, thereby preventing impurities from continuously clogging the filter holes of the filter screen 61.

[0022] A positioning device 4 is provided to assist the user in connecting the oil inlet pipe body 1 and the oil outlet pipe port 2. Before the connection, the movable sleeve 41 is pressed downward, and at this time, the oil inlet pipe body 1 is pushed into the inner wall of the oil outlet pipe port 2. When the movable sleeve 41 is pressed downward, the storage spring 42 is squeezed and starts to store force, and the gap between the movable sleeve 41 and the oil outlet pipe port 2 moves to the position of the sliding ball 43. In the process of the oil inlet pipe body 1 entering the position of the oil outlet pipe port 2, the sliding ball 43 is pushed into the gap between the movable sleeve 41 and the oil outlet pipe port 2, so that the oil inlet pipe body 1 can be smoothly delivered into the inside of the oil outlet pipe port 2. When the oil pipe body 1 completely enters the oil outlet pipe port 2, the groove position of the oil inlet pipe body 1 is aligned with the movable groove 44. At the same time, the downward pressure on the movable sleeve 41 is released, so that the force storage spring 42 pushes the movable sleeve 41 to move upward, and the movable sleeve 41 pushes the sliding bead 43 to move to the groove position of the oil inlet pipe body 1, thereby completing the initial fixation of the oil inlet pipe body 1 and the oil outlet pipe port 2, which is convenient for the user to free up one hand, move the movable sliding threaded sleeve 7, and screw the sliding threaded sleeve 7 into the threaded position of the oil outlet pipe port 2, thereby achieving complete fixation of the oil inlet pipe body 1 and the oil outlet pipe port 2.
