By rotating the second threaded rod 9, the threaded seat 10 can drive the screw blower body 1 to make horizontal movements in the front and rear directions, so that the position of the screw blower body 1 can be adjusted after the screw blower body 1 is fixed.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the first threaded rod 6 extends out of the outer part of the rotating seat 2 and is fixedly sleeved with a first pulley 16 on the outer circumferential surface, and a first connecting belt 17 is provided at the middle position of the two first pulleys 16; the second threaded rod 9 extends out of the outer part of the adjacent movable seat 8 and is fixedly sleeved with a second pulley 18, and a second connecting belt 19 is provided at the middle position of the two second pulleys 18. By rotating one of the first threaded rods 6, one of the first pulleys 16 is driven to rotate, so that under the connecting action of the first connecting belt 17, the other first pulley 16 can drive the other first threaded rod 6 to rotate, and by rotating one of the second threaded rods 9, one of the second pulleys 18 can be driven to rotate, so that under the connecting action of the second connecting belt 19, the other second pulley 18 can drive the other second threaded rod 9 to rotate.

[0022] Further as Figure 1As shown, it is worth explaining in detail that a rotating rod 4 is rotatably connected to one side of the top surface of the support seat 3, and the rotating rod 4 is fixedly sleeved and connected to the surface of the bottom of the rotating seat 2, a bubble level 14 is fixed to the surface of one end of the rotating seat 2, and a hydraulic cylinder 20 is fixed to the other side of the top surface of the support seat 3, and a connecting plate 21 is fixed to the output end of the hydraulic cylinder 20, and two tooth plates 22 are fixed to one side of the connecting plate 21, and gears 23 are fixedly sleeved at both ends of the outer circumference of the rotating rod 4, and the gears 23 are meshingly connected to the tooth plates 22 in adjacent positions.

[0023] Further Figure 3 As shown, it is worth explaining in detail that a T-shaped limit groove 24 is provided on the outer peripheral surface of the top surface of the support seat 3 located at the bottom of the connecting plate 21, and a T-shaped limit block 25 is inserted inside the limit groove 24. The top of the limit block 25 passes through the limit groove 24 and is fixed to the surface of the connecting plate 21. Since the limit block 25 can only slide on the inner cavity trajectory of the limit groove 24, and due to the shape settings of the two, the interference and limiting effect of the inner cavity of the limit groove 24 on the limit block 25 is improved, thereby being able to limit the movement trajectory of the connecting plate 21.

[0024] This solution has the following working process: in actual use, when the user needs to fix the screw blower body 1, the plug plate 11 at the bottom of the screw blower body 1 is extended to the inside of the threaded seat 10, and then the bolt 13 is extended to the inside of the adjacent position plug hole 12 under the cooperation of the threaded structure between the adjacent position movable seat 8, so that the screw blower body 1 can be fixed. When the position of the screw blower body 1 needs to be adjusted after it is fixed, the inner cavity of the first rod groove 5 and the inner cavity of the surface of the movable seat 8 can play a role of resisting and limiting the threaded sleeve 7 and the threaded seat 10, so that the threaded sleeve 7 can only move horizontally in the left and right directions and the threaded seat 10 can only move horizontally in the front and back directions. By rotating one of the first threaded rods 6, one of the first pulleys 16 is driven to rotate, so that the other first pulley 16 can drive the other first threaded rod 6 to rotate under the connection action of the first connecting belt 17, so that the two groups of threaded sleeves 7 can be connected between the internal thread structure of the inner wall and the first thread Under the cooperation between the external thread structures on the outer circumference of the rod 6, the threaded sleeve 7 can drive the two movable seats 8 to drive the screw blower body 1 to make horizontal movements in the left and right directions. By rotating one of the second threaded rods 9, one of the second pulleys 18 can be driven to rotate, so that under the connection of the second connecting belt 19, the other second pulley 18 can drive the other second threaded rod 9 to rotate, so that under the cooperation between the internal thread structure on the inner wall of the threaded seat 10 and the external thread structure on the outer circumference of the second threaded rod 9, the threaded seat 10 can drive the screw blower body 1 to make horizontal movements in the front and rear directions. When it is judged that the screw blower body 1 is in a tilted state by observing the bubble level 14, by controlling the length of the output end of the hydraulic cylinder 20, the connecting plate 21 can drive the tooth plate 22 to move in the horizontal direction, so that under the meshing action between the tooth plate 22 and the gear 23, the rotating rod 4 can drive the rotating seat 2 to rotate, so that the rotating seat 2 can drive the screw blower body 1 to adjust to a horizontal state.

[0025] According to the above working process, it can be known that: by rotating the first threaded rod 6, the movable seat 8 can drive the screw blower body 1 to make horizontal movements in the left and right directions, and by rotating the second threaded rod 9, the threaded seat 10 can drive the screw blower body 1 to make horizontal movements in the front and rear directions, so that the position of the screw blower body 1 can be adjusted after the screw blower body 1 is fixed, so that the screw blower body 1 can be adjusted to the corresponding suitable position, and the screw blower body 1 does not need to be disassembled for adjustment, thereby improving the convenience of use of the device, and judging whether the screw blower body 1 is in a horizontal state by observing the bubble level 14, and by controlling the extension length of the output end of the hydraulic cylinder 20, the rotating seat 2 can drive the screw blower body 1 to adjust to a horizontal state under the meshing action of the tooth plate 22 and the gear 23, thereby ensuring that the screw blower body 1 can be in a horizontal state, thereby ensuring the stability of use of the device.

[0026] Further as Figure 4 As shown, it is worth explaining in detail that support rods 15 are inserted through the surfaces of both ends of the movable seat 8, and the surfaces on both sides of the support rods 15 are fixed to the surface of the rotating seat 2. Since the movable seat 8 can only slide on the outer peripheral surface of the support rods 15 during horizontal movement, the support rods 15 can support the movable seat 81 to make its movement state more stable.

[0027] In summary: by rotating the first threaded rod 6, the movable seat 8 can drive the screw blower body 1 to make horizontal movements in the left and right directions, and by rotating the second threaded rod 9, the threaded seat 10 can drive the screw blower body 1 to make horizontal movements in the front and back directions, so that after the screw blower body 1 is fixed, the position of the screw blower body 1 can be adjusted, so that the screw blower body 1 can be adjusted to a corresponding suitable position, and the screw blower body 1 does not need to be disassembled for adjustment, thereby improving the convenience of use of the device, and by observing the bubble level 1 4 determines whether the screw blower body 1 is in a horizontal state, and controls the extension length of the output end of the hydraulic cylinder 20, so that the rotating seat 2 can drive the screw blower body 1 to adjust to a horizontal state under the meshing action between the tooth plate 22 and the gear 23, thereby ensuring that the screw blower body 1 can be in a horizontal state, thereby ensuring the stability of the device. Since the movable seat 8 can only slide on the outer peripheral surface of the support rod 15 during the horizontal movement, the support rod 15 can support the movable seat 81 to make its movement state more stable.

[0028] The hydraulic cylinder 20 can be purchased on the market. The hydraulic cylinder 20 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
