s1: firstly, a clamping plate (24) positioned on a first plate (2) is lifted upwards, the clamping plate (24) drives a mounting plate (10) to move upwards through a sliding rod (9), at the moment, the mounting plate (10) extrudes a first spring (12) and drives a first rubber pad (11) to move upwards, so that the first rubber pad (11) is separated from a second rubber pad (23), at the moment, one end of a carbon brush to be tested is placed into a first hole (6), the clamping plate (24) is loosened, the mounting plate (10) moves downwards under the action of the elastic force of the first spring (12), so that the first rubber pad (11) extrudes one end of the carbon brush to be tested downwards, one end of the carbon brush to be tested is stably positioned in the first hole (6), at the moment, a hand wheel (25) positioned on the first plate (2) is rotated, the hand wheel (25) drives one of reel (15) to start rotating through a rotating shaft (14), and a traction rope (16) can be wound when the winding wheel, at the moment, the other end of the traction rope (16) pulls the second plate (5) to move towards the direction close to the first plate (2), and the second plate (5) can extrude the second spring (17) to be in a compressed state;
s2: when the central point of the traction rope (16) moves into the first plate (2), the knob on the first plate (2) is rotated at the moment, the knob drives the locking screw (20) to rotate in the threaded hole (19), and the locking screw (20) drives the locking screw to move downwards due to the fact that the locking screw (20) is in threaded connection with the corresponding threaded hole (19), so that the locking screw (20) drives the hemispherical rubber pad (21) to move downwards at the moment, the bottom side of the hemispherical rubber pad (21) is in contact with and tightly attached to the top side of the reel (15) in the first plate (2), the position of the reel (15) in the first plate (2) can be fixed, and the reel (15) in the first plate (2) cannot rotate any more;
s3: lifting a clamping plate (24) on a second plate (5) upwards to enable the other end of the carbon brush to be tested to be stably positioned in a second hole (7), rotating a knob on a first plate (2) in the opposite direction, driving a locking screw rod (20) to start rotating by the knob, driving the locking screw rod (20) to move upwards, driving a hemispherical rubber pad (21) to move upwards by the locking screw rod (20) to be separated from a reel (15), driving the second plate (5) to move in the direction away from the first plate (2) by the elasticity of a second spring (17), driving the other end of the carbon brush to be tested to move in the direction away from the first plate (2) by the second plate (5) through a first rubber pad (11), enabling the carbon brush to be tested to be unfolded, reading the distance between the two ends of the carbon brush to be tested through a scale mark (26) on a positioning rod (4) when the carbon brush to be tested is unfolded to the maximum length, taking a, the two ends of the universal meter are respectively connected to the two ends of the carbon brush to be tested, so that the resistance value between the two ends of the carbon brush to be tested can be measured, and the resistivity of the carbon brush to be tested can be rapidly calculated by combining the length between the two ends of the carbon brush to be tested.
