The working principle of the nerve monitoring device disclosed by the invention is as follows: when the patient lies on the bed plate 101, the patient can lie on the bed plate 101 directly, and then according to the current swing position of the L-shaped bracket 201, when needing to explain, when operating, the patient needs to apply saline first, and then contacts the electrode with the body, that is, when the patient lies on the bed plate 101, the wiping motor 202 needs to be adjusted to the position shown in fig. 1.

The patient can adjust the patient by moving the adjusting control frame 2123, as shown in fig. 7, when the adjusting control frame 2123 moves to the left end or the right end of the first control slide rod 2121, the input contact 2125 on the adjusting control frame 2123 contacts with the output contacts 2124 on the first control slide rod 2121 and the second control slide rod 2122, and at this time, the power is turned on, it should be noted that the input contact 2125 is the power input end, the right output contact 2124 and the left output contact 2124 are respectively electrically connected to different control electromagnets 2183, so that the contact of the input contact 2125 with the output contacts 2124 at different positions controls one of the two control electromagnets 2183 to be energized, and thus generate magnetic force, as shown in fig. 12, the tension spring rod support 218 is fixedly installed on the sliding plate 215, the tension spring rod 2181 is fixedly installed on the tension spring rod support 218, the limit piece 2184 is fixedly installed on the tension spring rod 2181, the tension spring rod 2181 is composed of a telescopic cylinder and a movable rod, and a tension spring is arranged in the tension spring, when external force is not applied, the movable rod is contracted in the telescopic cylinder, if the right control electromagnet 2183 is electrified, the limiting sheet 2184 is attracted to come down, meanwhile, the O-shaped block on the reset spring 2185 is fixed on the limiting cylinder 2182 again due to the attraction of the control electromagnet 2183, at this time, any change does not occur between the limiting rod 217 on the other side and the limiting cylinder 2182, and the limiting sheet can move freely relatively, as shown in fig. 11, when the sliding plate 215 moves to the left, the dial plate 216 also moves together, the top end of the dial plate 216 is forced to the right from the dial gear 207, so the top end of the dial plate 216 swings to the right, and the bottom end swings to the left, at this time, the limiting rod 217 slides to the left, at this time, the reset spring 2185 on the right is in a stretched state, and it should be noted that, the rotation of the dial gear 207 has resistance, therefore, the movement of the toggle piece 216 to the left does not drive the toggle gear 207 to rotate, when the sliding plate 215 moves to the right, the toggle piece 216 also moves to the right, the top end of the toggle piece 216 is subjected to a force from the toggle gear 207 to the left, so that the top end of the toggle piece 216 swings to the left, and the bottom end swings to the right, at this time, the limiting rod 217 tends to slide to the left, because the limiting rod 217 is blocked by the limiting piece 2184 falling down, so that the limiting rod 217 cannot move, the toggle piece 216 drives the toggle gear 207 to rotate by a corresponding angle, the movement of the sliding plate 215 is controlled by the driving electromagnet 210, when the driving electromagnet 210 generates a magnetic pole identical to that of the permanent magnet 213, the sliding plate 215 moves to the right, otherwise, when the sliding plate 215 moves to the left, the spring 214 is stretched to contact with the normally open button 211 fixed on the pressing plate 206, when the sliding plate 215 moves to the left, the spring 214 is compressed to contact with the normally open button 211 fixed on the driving electromagnet 210, when the sliding plate 215 presses the normally open button 211 to the normally open electromagnet 211, when the sliding plate 215 is not powered, the driving electromagnet, the spring 215 is not powered, the sliding plate 215 is rapidly-down, so that the sliding plate 213 is pressed to reduce the speed of the permanent magnet 213, and the sliding plate 213 is controlled by the slow speed of the permanent magnet 213, so that the permanent magnet 213 is reduced.

The rotation direction of the toggle gear 207 can be controlled by controlling the adjusting control bracket 2123 to make the input contact 2125 contact with a different output contact 2124 and to drive the electromagnet 210 to generate a magnetic pole in the same direction as the magnetic pole of the permanent magnet 213.
