AI Technical Summary
Traditional protective plates in wire tensile testing equipment lack a buffer mechanism, leading to a large impact force when wire fragments hit, which reduces their service life.
A telescopic plate with telescopic springs is installed on the stretching machine body, absorbing the impact of flying wire fragments and extending the service life by compressing the springs.
The telescopic plate mechanism prevents staff injuries by absorbing impact and extends the protective plate's service life through buffering, while also providing a larger operating space for wire clamping and removal.
