[0046] Embodiment 3

[0047] Based on Example 1, see Figure 1 , Figure 3 and Figure 6-9 shown.

[0048] The top of the rotating disk 4454 is provided with a positioning groove 9 and an auxiliary groove 10, four of which are symmetrically arranged along the top center of the rotating disk 4454. A convex rod 11 used in conjunction with the positioning groove 9 is fixedly connected to the groove 8, and one end of the convex rod 11 is arranged in an arc surface. After the vagus nerve stimulator body 1 and the mounting cover 2 are separated, the rotating disk 4454 fits with the convex rod 11, and the first spring 454 in a compressed state will recover, thereby driving the upper hook plate 41 to recover, thereby driving the fixed arm 444 and the connecting arm 443 to recover, so that the connecting arm 443 drives the disk 442 to rotate, and then drives the rotating shaft 441 to rotate, and under the action of the clamping groove 4452 and the clamping strip 4453, the sleeve 4451 will be driven to rotate, thereby driving the rotating disk 4454 to rotate and recover, and then the second spring 4455 in a compressed state recovers, and then the convex rod 11 is stuck in the positioning groove 9 to position the rotating disk 4454.

[0049] Embodiment 4

[0050] In combination with Embodiment 1, Embodiment 2 and Embodiment 3, see Figure 1-10 shown.

[0051] By directly docking the vagus nerve stimulator body 1 and the mounting cover 2, the vagus nerve stimulator body 1 and the mounting cover 2 can be easily fixed, and the turntable 4454 is hidden in the concave cavity 7 and will not rotate easily. When disassembling, the vagus nerve stimulator body 1 and the mounting cover 2 can be disassembled by pressing and rotating 4454, which is easy to use.

[0052] The working principle of the present invention is as follows: when fixing the vagus nerve stimulator body 1 and the mounting cover 2, the vagus nerve stimulator body 1 and the mounting cover 2 are docked with each other, and then the lower hook plate 42 is fitted on the inner wall of the mounting cover 2 and moves. When the inclined surfaces between the lower hook plate 42 and the upper hook plate 41 come into contact, the upper hook plate 41 is moved by utilizing the inclined surface between the upper hook plate 41 and the lower hook plate 42, thereby driving the fixed arm 444 to move, and then driving the connecting arm 443 to move, while the disc 442 does not rotate, and the first spring 454 is in a compressed state under force. When the inclined surface portion of the upper hook plate 41 moves to below the inclined surface portion of the lower hook plate 42, the first spring 454 in a compressed state recovers, thereby driving the upper hook plate 41, the fixed arm 444 and the connecting arm 443 to recover, and then the upper hook plate 41 and the lower hook plate 42 are mutually clamped together, thereby achieving the fixation of the vagus nerve stimulator body 1 and the mounting cover 2.

[0053] When disassembling the vagus nerve stimulator body 1 and the mounting cover 2, two fingers are placed on the two auxiliary grooves 10 in relative positions, and then the turntable 4454 is pressed to drive the sleeve 4451 to slide down along the rotating shaft 441, and the second spring 4455 is in a compressed state. When the positioning groove 9 and the protruding rod 11 are completely separated, the turntable 4454 is rotated to drive the sleeve 4451 to rotate, and under the action of the clamping strip 4453 and the clamping groove 4452, the rotating shaft 441 is driven to rotate. The disk 442 is driven to rotate, so that the disk 442 pulls the connecting arm 443 and drives the connecting arm 443 to move, and then the connecting arm 443 drives the fixed arm 444 to move, thereby driving the upper hook plate 41 to move, and the upper hook plate 41 and the lower hook plate 42 are gradually separated, and 454 is in a compressed state under force. When the upper hook plate 41 and the lower hook plate 42 are completely separated, the installation cover 2 can be removed from the vagus nerve stimulator body 1 to replace the electrode 12 on the vagus nerve stimulator body 1.

[0054] After the vagus nerve stimulator body 1 and the mounting cover 2 are separated, the turntable 4454 fits with the protruding rod 11, and the first spring 454 in a compressed state will recover, thereby driving the upper hook plate 41 to recover, thereby driving the fixed arm 444 and the connecting arm 443 to recover, so that the connecting arm 443 drives the disc 442 to rotate, and then drives the rotating shaft 441 to rotate, and under the action of the slot 4452 and the strip 4453, the sleeve 4451 will be driven to rotate, thereby driving the turntable 4454 to rotate and recover, and then, the second spring 4455 in a compressed state recovers, and then the protruding rod 11 is stuck in the positioning slot 9 to position the turntable 4454.

[0055] During the disassembly of the vagus nerve stimulator body 1 and the mounting cover 2, the large pulley 32 will rotate along with the rotating shaft 441, and then drive the small pulley 34 to rotate through the belt 35, thereby driving the shaft 31 to rotate, and then driving the connector 36 to rotate. During the rotation of the connector 36, the inclined surface at the bottom of the connector 36 gradually contacts the downward pressure rod 33, so that the downward pressure rod 33 gradually moves downward along the fixed block 451. Under the thrust of the downward pressure rod 33, relative movement occurs between the vagus nerve stimulator body 1 and the mounting cover 2, avoiding the vagus nerve stimulator body 1 and the mounting cover 2 being fixed again due to error, which is conducive to the disassembly of the vagus nerve stimulator body 1 and the mounting cover 2.

[0056] During the downward movement of the pressure rod 33, the third spring 372 is in an extended state. When the turntable 4454 is restored, the large pulley 32, the belt 35 and the small pulley 34 drive the shaft rod 31 to restore, thereby driving the connecting body 36 to restore, and then the third spring 372 restores and drives the pressure rod 33 to restore, so that the entire device can be used next time.

[0057] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
