The working principle is as follows: when the invention is used, firstly, the resistor body is evenly placed on the conveying belt of the conveyor 2, when the resistor body is detected to enter the detection box body 30, the output shaft of the first motor 31 rotates to drive the eccentric block 32 to rotate, the driving head 34 is driven by the rotating rod 33 to slide in the horizontal sliding slot of the lifting plate 35, the lifting plate 35 moves downwards along the vertical guide rail 36, thereby moving the sensing probe 38 downward together, when the sensing probe 314 contacts the sensing site of the resistor body, a reverse force is applied to the sensing probe 314 to compress the pre-crash spring 315, and when the sensed resistance value is obtained, the elevating plate 35 is lifted up, the detection of the current resistor body is ended, the transmission speed of the conveyor 2 is set to be slow, and the contact time of the detection probe 314 and the detection point of the resistor body is short, so the conveyor 2 does not need to be stopped for detection;

the resistor body which is detected continues to move forwards on the conveyor belt of the conveyor 2, if the detected resistance value of the current resistor body is not consistent with the rated resistance value, the resistor body reaches the position under the vertical mounting plate 45, the piston rod of the telescopic cylinder 44 extends out to drive the lifting slide block 47 to move, when the two fixing rods 49 contact the side wall of the triangular boss 46, the two clamping rods 411 are close to each other, the two clamping heads 412 are close to each other, and the resistor body is clamped;

after the clamping is completed, the second motor 41 is started, the gear is in transmission fit with the arc-shaped rack to drive the rotating rod 42 to rotate, so that the resistor body is positioned right above the sorting chute, then the piston rod of the telescopic cylinder 44 returns, the two clamping rods 411 are far away from each other under the action of the compression spring 410, so that the resistor body falls on the sorting chute and slides out;

when the specification of the resistor body to be detected is changed, the distance adjusting knob 39 is pulled outwards, so that the rotating shaft 310 and the spline tooth groove block 312 are driven to be disengaged, the distance adjusting knob 39 is rotated at the moment, under the combined action of the traction rope and the spring, the distance between the two mounting blocks 37 is changed, and the distance between the detection points of the existing resistor body is matched.
