The measuring part 2 includes a measuring table 21, which is located on the storage table 11. The measuring table 21 is parallel to the moving direction of the pipe 7. The measuring table 21 is marked with scale lines 221. The scale of the scale lines 221 corresponds to the cutting length of the cutting saw 31, which is convenient for workers to observe the cutting length of the pipe 7. This equipment is used for workers to quickly control and determine the cutting length of the pipe 7, facilitate sawing and adjusting the length, save the measurement time of the pipe 7, and improve production efficiency. On the other hand, the cutting length accuracy of the pipe 7 is improved, and it can be accurately sawed to meet customer needs; a slide groove 211 is opened on the measuring table 21, and a gauge block 23 is slidably provided on the slide groove 211. When the pipe 7 is transported toward the storage table 11, the head end of the pipe 7 is against the gauge block 23.
