At this time, the handle 507 drives the baffle 506 to move backward to the inside of the rear end surface of the storage box 501, and then the hanging ring 7 is pulled outward. The hanging ring 7 is made of soft rubber material and can be bent. Then, the ring 9 is fixed on the first anchor rod under the action of the magnet 8, and then the hollow round rod 1 is pulled by the handle 2 to move it to the position of the second anchor rod. At this time, under the action of the tension, the measuring leather rope 304 is pulled, so that the take-up wheel 303 rotates, and the handle 2 is moved to the position of the second anchor rod. Then, the reading is read, the measurement is completed, and then the hollow round rod 1 is moved to the first anchor rod by the handle 2, and the hanging ring 7 is removed from the outside of the first anchor rod. The set guide frame 401 can protect the measuring leather rope 304 and play a guiding purpose to prevent it from being entangled in the hollow round rod 1, and the set guide ring 402 ensures that the measuring leather rope 304 is not easily worn, thereby ensuring its normal service life.
