A movable mechanism is fixedly connected to the bottom of the movable slider 1, and a left semicircular fixing piece is provided on one side of the movable mechanism. The two ends of the left semicircular fixing piece are fixedly connected to connecting blocks, and one side of the connecting block is fixedly connected to a fixing block. A right semicircular fixing piece is provided on one side of the left semicircular fixing piece, and the two ends of the right semicircular fixing piece are fixedly connected to connecting blocks, and a bolt 1 is provided on one side of the connecting block. The movable mechanism includes a driving motor, and a screw rod is fixedly connected to the output end of the driving motor. A limiting plate is provided on one side of the screw rod. The two ends of the limiting plate are respectively fixedly connected to a movable slider 1 and a movable slider 2. The driving motor is fixedly connected to the movable slider 2.

The rotating shaft 80 can be controlled to rotate to drive the ball screws 20 on both sides to rotate simultaneously.

[0037] The embodiment of the present disclosure provides a fixing device for a drainage pipe, comprising a support frame 10, a ball screw 20, a screw nut 30, a support plate 40, a clamp assembly 50, a first bevel gear 60, a second bevel gear 70, a rotating shaft 80 and a seat bearing 90. The ball screw 20 is rotatably mounted on the support frame 10 along the height direction of the support frame 10, and is located on both sides of the support frame 10 along the width direction of the support frame 10, and the ball screws 20 on both sides can perform rotational motion relative to the support frame 10. The screw nuts 30 are respectively mounted on the ball screws 20 on both sides, and are combined together to form a screw nut pair to convert the rotational motion into linear motion. The support plates 40 are respectively mounted on the screw nuts 30 on both sides, and are both slidably connected to the support frame 10, and can perform linear motion relative to the support frame 10. The clamp assembly 50 is installed between the support plates 40 on both sides, and is used to clamp the drainage pipe to fix the drainage pipe. The first bevel gears 60 are respectively mounted on the ends of the ball screws 20 on both sides, and rotate synchronously with the ball screws 20 on both sides.

The seat bearing 90 is mounted on the rotating shaft 80 and installed on the support frame 10, and is used to determine the position of the rotating shaft 80. Among them, the rotating shaft 80 can be controlled to rotate to drive the ball screws 20 on both sides to rotate simultaneously.

[0038] During use, under the action of external force, the rotating shaft 80 can rotate, thereby driving the second bevel gears 70 on both sides to rotate simultaneously. Under the meshing action between the teeth, the first bevel gears 60 on both sides can rotate simultaneously, thereby driving the ball screws 20 on both sides to rotate simultaneously. Then, the nuts 30 on both sides of the screws can drive the support plates 40 on both sides to slide relative to the support frame 10 at the same time, thereby changing the position of the clamp assembly 50. Finally, the position of the drainage pipe is changed so that the distance of the drainage pipe fixture can be determined according to the complex distribution inside the drainage pipe. Because the design of the rotating shaft 80 allows the ball screws 20 on both sides to always rotate simultaneously, it can avoid the phenomenon of jamming and eliminate safety hazards.
