When personnel use untested hard links, there is a risk of potential accidents such as breakage of the connection device or excessive dragging force resulting in personal injury or death.
[0027] In order to solve the above-mentioned problems, the present application proposes a tension detection device for a mine workshop connection device. The embodiments of the present application are further explained below in conjunction with the accompanying drawings.

[0029] It should be noted that the tensile testing equipment used for the mine workshop connection device is easy to disassemble during use, and the place of use can be adjusted according to the use environment, breaking away from the basic constraints of the place of use.
[0030] In this embodiment, the test bench frame 110 uses I-beams as the bottom frame, and the bottom frame is reinforced with mining I-beams and welded with fixing points.
