[0026] In this embodiment, the size of the annular groove 3 is adapted to the size of the slider 4, so that the first bevel gear 5 connected to the slider 4 can be limited by the annular groove 3, thereby improving the stability of the first bevel gear 5 during rotation; the outer edge of the first bevel gear 5 is meshed with the outer edge of the second bevel gear 6, so that the device body 12 can be driven to rotate along the annular groove 3 by starting the motor 8 to achieve power transmission; the size of the fixing frame 9 is adapted to the size of the motor 8, so that the motor 8 can be protected by the fixing frame 9, thereby improving the service life of the motor 8; there are several groups of elastic balls 103, and the elastic balls 103 are arranged in a plurality of groups.

This design enables the device to have a buffering function and avoids the device from being damaged during paving and moving. During the process, facing the bumpy road, the road surface produces a large vibration, which can easily cause the precision parts or pipes on the device to be damaged or broken. When the direction of the pipe needs to be adjusted, the first bevel gear 5 connected by the slider 4 and the second bevel gear 6 connected by the rotating shaft 7 are meshed with each other, so that the start of the motor 8 in the fixed frame 9 can drive the device body 12 on the hydraulic cylinder 11 to rotate along the annular groove 3 on the base 1, so that the laying workers can directly adjust the direction of the pipeline. This design enables the device to have the function of rotating and adjusting the direction, avoiding the problem that the device cannot directly adjust the direction of the pipeline according to the laying needs when laying the pipeline, thereby causing many inconveniences to the laying workers.
