[0002] Conductive tubes are typically designed to be retractable to accommodate varying lengths. However, the locking buttons on conventional conductive tubes use a radially pressed mechanism to loosen and lock the inner and outer tubes. This creates significant pressure on the tube and lacks positioning stability and ease of operation. Conventional testing devices for button telescopic fatigue performance also provide unstable positioning of the tube, causing it to shift when the button is pressed. This results in inaccurate test results and can easily damage the tube. Utility Model Content
