[0002] After the tape is processed, a life tester is needed to measure the life of the tape.

[0003] The existing tape measurement method usually uses one-side setting to test the product. When pulling the tape back and forth, the device works half of the time to pull the tape, and the other half of the time is wasted, which reduces the number of products detected by the device and affects the improvement of the working efficiency of the device. In view of the above situation, technical innovation is carried out on the basis of the existing tape. For this purpose, we propose a tape measure life tester. Utility Model Content
