[0002] A test fixture refers to a tool or device used to clamp and fix multi-channel batteries, generally composed of a fixture body and a clamping mechanism, and is used to fix multi-channel batteries at a specific position to test their discharge performance, and is an essential test device in the R & D process.

[0003] When replacing samples in the traditional fixture, it is necessary to assemble them one by one in the order of the lower end plate, insulating plate, cathode current collector plate, cathode flow field plate, membrane electrode, anode flow field plate, anode current collector plate, insulating plate, and upper end plate. After assembly, horizontal positioning is carried out through multiple bolts. When tightening, first pre-tighten, and then tighten diagonally respectively, or press with high-pressure air source.

[0004] However, the fixture is usually assembled manually, with complex operations and long time consumption. The uniformity of the pressing force of the membrane electrode cannot be guaranteed. Moreover, when using a high-pressure air source to apply the pressing force, the test bench is required to have an air source supply interface, which has high requirements for the test bench, and there is a risk of air leakage. The size of the pressing force cannot be adjusted flexibly, and the requirements for operators are also high, which affects the test efficiency and accuracy. Summary of the Utility Model
