[0002] In vehicle design, various types of switch systems integrated on the handlebar play a crucial control function, and their reliability and durability are directly related to the driving experience and safety. Therefore, it is necessary to conduct fatigue tests on the handlebar switches, and the process is to perform on-off actions on the switches in a high-temperature environment. In the prior art, a cylinder is used as the power source to drive the execution component to achieve the on-off action of the switch. However, since the temperature of the test machine box is above 60°C, the cylinder and its supporting air pipeline system face severe tests. The high temperature not only accelerates the aging process of the material but also may cause gas pressure fluctuations, thereby affecting the working stability and efficiency of the cylinder. In the long run, it will significantly shorten the service life of the air pipeline, increase the maintenance cost, and even pose potential safety hazards. Summary of the Invention
