10. The system of claim 3, wherein the hardware fitting comprises: the specific detection test method of the electric power fitting wear resistance detection test system comprises the following steps:
s1, equipment inspection: before the electric power fitting wear resistance detection test system is started to detect the wear resistance of the electric power fitting, the electric power fitting is checked;
s2, adjusting a test position: after the equipment inspection is finished, the locking rod (552) is pulled out to the outer side through manual work, the transverse plate (53) is separated from the adjusting block (54), the left and right positions of the fixed hook (563) are adjusted through the adjusting block (54), the rotating screw (44) is rotated manually, the connecting plate (43) drives the extrusion plate (41) to move along the guide rod (45), the extrusion plate (41) extrudes the sliding rod (561) to adjust the height position of the fixed hook (563), and then the testing position is adjusted;
s3, feeding treatment: after the test position is adjusted, the electric power fitting to be tested is manually clamped in the fixed hook (563), so that the fixed spring (566) drives the rotating rod (564) to clamp the opening of the fixed hook (563), and the electric power fitting is locked and fixed by the fixed hook (563);
s4, testing treatment: after the electric power fitting is locked and fixed, the free end of the test rope (524) sequentially penetrates through the electric power fitting along the wave shape and is wound on the outer side of the second winding roller (526) by manpower, and the test motor (522) drives the second winding roller (526) to loosen and wind the test rope (524) through the coil spring (528) while winding and loosening the test rope (524) through the first winding roller (523), so that the test rope (524) tests the electric power fitting;
s5, blanking observation: after the test rope (524) tests the electric power fitting for a period of time, the tested electric power fitting is taken down manually and compared with the electric power fitting which is not tested, so that the wear resistance of the electric power fitting is obtained.
