Background
In the use process of the existing folding knife, the rotating shaft and the button are gradually abraded, so that the opening and closing function of the folding knife is invalid, and therefore, the opening and closing service life test needs to be carried out;
for example, chinese patent CN201710324305.1 discloses a scissors performance testing device, which comprises a supporting body, a first slide rail, a movable assembly slidably mounted on the first slide rail, a fixed assembly fixed on the first slide rail, and a first transmission mechanism for driving the movable assembly to slide, so as to form a scissors performance testing device, wherein the movable assembly and the fixed assembly are respectively used for mounting a first scissors body and a second scissors body of a tested scissors during testing, the sliding of the movable assembly relative to the fixed assembly drives the first scissors body of the tested scissors to rotate relative to the second scissors body, so as to simulate the operation process of using the scissors in production and life, and the movable assembly is provided with a pressure sensor for collecting the pressure required for driving the scissors to open and close during the testing process and inputting the pressure into a control processor for processing, so as to equivalently quantify the force required during the operation process of the tested scissors, the distribution condition of the required force under different opening and closing degrees of the tested scissors in the using process of the tested scissors can be efficiently and accurately analyzed;
for example, chinese patent CN201710324305.1 discloses a shear durable shearing force testing device, which comprises a feeding mechanism and a testing mechanism, wherein the feeding mechanism adopts a roller-driven cloth-rolling tube feeding structure, and the testing mechanism is located below the feeding mechanism and comprises a base, and a shear positioning assembly and a shear opening and closing driving assembly which are arranged on the base; the feeding mechanism comprises a substrate, a fixed point shaft, a shaping shaft, a transmission shaft and a feeding motor, wherein the fixed point shaft, the shaping shaft and the transmission shaft are positioned on one side of the substrate, the feeding motor is positioned on the opposite side of the substrate, the fixed point shaft is fixed on the substrate, the shaping shaft and the transmission shaft are movably arranged on the substrate, and the feeding motor is in transmission connection and matching with the transmission shaft through a belt; the scissors positioning component of the testing mechanism comprises a positioning support arranged above the base, at least one turning T-shaped positioning groove arranged at the top of the positioning support, and at least one positioning lock rod embedded in the turning T-shaped positioning groove and used for locking a single arm of scissors; the scissors opening and closing driving assembly of the testing mechanism comprises an opening and closing motor arranged in a base, a rotating main shaft positioned in the base through a rotating shaft piece, and a rotating push rod matched with the upper end of the rotating main shaft extending out of the base through a rotating arm;
