[0002] The sling is currently widely used in steel plants, shipyards and papermaking and other manufacturing industries. The load capacity of the sling is the main performance standard for enterprises to purchase and accept. The sling tensile test is generally carried out on a tensile testing machine. At present, the general tensile testing machine clamps and stretches the sample by using the jaw. The jaw of the tensile testing machine is not easy to clamp and fix the sling. Therefore, when the sling tensile test is carried out, the sling is generally installed and fixed on the test device, and then the jaw of the tensile testing machine clamps the test device, so as to complete the sling tensile test.

[0003] The existing test device generally includes a first fixed seat and a second fixed seat.

The sling is arranged around the upper shaft pin and the lower shaft pin. Then start the tensile testing machine to complete the tensile test of the sling.

[0004] In view of the related technology in the above, the sling is clamped and fixed by the upper shaft pin and the lower shaft pin. When the tensile testing machine is stretched, the stretching stroke is too long, which makes it difficult to stretch the longer sling. SUMMARY
