One end of the aiming table is fixedly connected with one end of the workbench, the other end of the aiming table is fixedly connected with the bottoms of the inner sides of the two supporting side plates, and an automatic conveying mechanism is arranged at the top of the workbench. Through the synchronous measuring assembly, the measuring scale and the sample cloth can move synchronously, the two ends of the reference plate are fixedly connected to the upper portion of the measuring scale, the reference plate is located above the junction of the workbench and the aiming table, and therefore when the test value of the sample cloth needs to be read, the value on the measuring scale can be read through the reference plate, and the measurement accuracy is improved. The sample cloth is prevented from being pushed by manually pushing the measuring scale, the efficiency is improved, and the manpower is saved.
