Description

Technical Field

[0001] The utility model relates to the technical field of fabric detection equipment, in particular to a digital fabric tearing instrument. Background Art

[0002] Digital fabric tear tester is suitable for measuring the tear strength of various woven fabrics, non-woven fabrics and coated fabrics. It also has the advantages of high automation, stable use and high precision. However, the existing digital fabric tear tester has a large swing arm when testing the tear strength. If the switch is pressed with one hand, it is very likely to cause harm to the operator. Since the two switches are located on both sides, it is slightly difficult for the operator to press the switches with both hands at the same time, and it will also consume some time. When multiple samples need to be tested, this not only increases the burden on the staff, but also reduces the detection efficiency.

[0003] The existing Chinese patent CN211978504U is a digital fabric tearing instrument. In actual use, when removing the weight, it is necessary to use external tools to unscrew nut 2. At the same time, when adjusting the height of the workbench, it is also necessary to use external tools to unscrew nut 1. Moreover, nut 1 is located at a relatively low position below the workbench. The above operation method is extremely inconvenient. Utility Model Content
