The knotted wires need to be untied when in use, which is extremely troublesome. At the same time, the traditional electrode installation method is not securely fixed, so the electrode will be separated from the connection when the patient's body moves, causing data collection interruption.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A fixed block 16 is fixedly installed on the bottom of the push piece 13, and an insertion pin 17 is fixedly installed on the outer wall of the fixed block 16. A disposable electrode sheet 11 is movably sleeved on the outer wall of the fixed block 16. In the above structure, the line 4 is wound around the outer wall of the winding column 3 at one end located inside the shell 1, so that when not in use, the winding column 3 winds the line 4 around the outer wall through the clockwork spring 9.

[0023] In a preferred embodiment, the shape of the ratchet 7 is adapted to the outer wall of the ratchet 5, and the outer wall of the ratchet 7 is meshed with the outer wall of the ratchet 5. In the above structure, when the ratchet 7 is meshed with the ratchet 5, the ratchet 5 cannot rotate. When the ratchet 7 is separated from the ratchet 5, the ratchet 5 can rotate.

[0024] In a preferred embodiment, the two ends of the extension spring 8 are overlapped with the top of the ratchet 7 and the top of the inner wall of the shell 1 respectively, and a platform is provided on the top of the ratchet 7, and the top of the platform is rotatably connected to the lower pressure column 6. In the above structure, by pressing down the lower pressure column 6, the lower pressure column 6 drives one end of the ratchet 7 to move downward, and the other end of the ratchet 7 moves upward, so that the ratchet 7 is disengaged from the ratchet wheel 5. At this time, the extension spring 8 is contracted. When the pressing force of the lower pressure column 6 disappears, the ratchet 7 is reset by the elastic force of the extension spring 8, so that the ratchet 7 and the ratchet wheel 5 are clamped.

[0025] In a preferred embodiment, the number of the pressing columns 12, the pushing pieces 13, the fixed card blocks 16 and the insertion pins 17 is two, and the two pressing columns 12, the pushing pieces 13, the fixed card blocks 16 and the insertion pins 17 are symmetrically distributed on both sides of the inner wall of the fixed head 10. In the above structure, by pressing the two pressing columns 12 at the same time, the two pressing columns 12 drive the two pushing pieces 13 to move toward the middle, and by placing the fixed card blocks 16 into the top of the disposable electrode sheet 11, the fixed card blocks 16 enter the interior of the disposable electrode sheet 11. At this time, the structure is reset so that the two insertion pins 17 clamp the top of the disposable electrode sheet 11.

[0026] In a preferred embodiment, the expansion spring 15 is located in the middle of the guide rail 14, and the expansion spring 15 overlaps the two push plates 13. In the above structure, the two expansion springs 15 are located between the two push plates 13, so that when the two push plates 13 move toward the middle, the expansion spring 15 continuously contracts. When the pressure of the push plates 13 disappears, the structure is reset by the tension of the two expansion springs 15.

[0027] In a preferred embodiment, the number of guide rails 14 and expansion springs 15 is two, and the two guide rails 14 and expansion springs 15 are symmetrically distributed on the inner wall of the fixed head 10, the two guide rails 14 penetrate the push piece 13, and the two guide rails 14 are slidably connected to the push piece 13. In the above structure, the push piece 13 is limited by the two guide rails 14, so that the two push pieces 13 can only move on the outer wall of the guide rails 14, so that the push piece 13 will not tilt when moving.

[0028] Working principle: when the device is needed, the line 4 is pulled to move the line 4 outward from the inside of the housing 1, and the winding column 3 is rotated outside the rotating shaft 2. The rotating shaft 2 drives the ratchet 5 to rotate, so that the outer wall of the ratchet 5 rotates outside the ratchet 7, so that the clamping point between the ratchet 7 and the ratchet 5 is constantly changed. At the same time, the clamping point between the ratchet 7 and the ratchet 5 prevents the winding column 3 from rotating in the opposite direction, and the shape of the clockwork spring 9 is changed. At this time, the disposable electrode sheet 11 is attached to the patient's examination site. When the line 4 needs to be stored after use, the pressing column 6 is pressed. The pressing column 6 drives one end of the ratchet 7 to move downward, and the other end of the ratchet 7 moves upward, so that the ratchet 7 is disengaged from the ratchet 5, and the extension spring 8 is contracted. At this time, the extension spring 8 is retracted. The tension spring 8 loses its locking relationship with the ratchet 7, at which time the clockwork spring 9 recovers, driving the winding column 3 to rotate, so that the winding column 3 reels the line 4. When the disposable electrode sheet 11 needs to be installed, the two pressing columns 12 are pressed at the same time, so that the two pressing columns 12 drive the two pushing pieces 13 to move toward the middle, so that the two pushing pieces 13 compress the expansion spring 15, and put the fixed card block 16 into the top of the disposable electrode sheet 11, so that the fixed card block 16 enters into the interior of the disposable electrode sheet 11. At this time, the two pressing columns 12 are released, and the structure is reset by the rebound force of the expansion spring 15. At this time, the outer wall of the fixed card block 16 is in contact with the inner wall of the disposable electrode sheet 11, and the insertion pin 17 enters into the inner wall of the disposable electrode sheet 11 to fix the disposable electrode sheet 11.
