Description

Technical Field

[0001] The utility model relates to the technical field of tension testers, in particular to a tension test device which is easy to adjust. Background Art

[0002] A tensile tester is a test device used to test the tensile properties of materials or components. It simulates the stress conditions in actual use by applying a tensile load and measures the tensile strength, elongation, elastic modulus and other parameters of the material.

[0003] The tensile tester is mainly composed of a frame, a sensor, a transmission system, a control system and a measuring system. The sensor is used to measure the load and deformation of the sample, the transmission system is used to apply the tensile load, the control system is used to set and control the test parameters, and the measuring system is used to record and display the test data. For example, the Chinese utility model patent disclosed by the existing publication number CN212844649U: a fabric tensile tester, the application sets an auxiliary mechanism, and sets a slot and an insert block to make the first clamping plate and the second clamping plate more secure when clamping the fabric. First, in the application, a single threaded column is used to control the first clamping plate and the second clamping plate to clamp and fix the fabric. Even if the slot and the insert block are matched, the force of the slot and the insert block on both sides of the threaded column to squeeze each other is insufficient. Therefore, the insert block and the slot cannot effectively clamp and fix the fabric. Secondly, the clamp used in the application can only perform clamping tests on fabrics or other flexible items. When performing tensile tests on other items, the clamp needs to be replaced, which makes the applicability of the clamp low. Utility Model Content
