In this embodiment, as shown in fig. 3 to 4, the inner surface of the fixing ring 42 is provided with a plurality of rotation stopping columns 43; the one end fixed mounting of stall post 43 is on solid fixed ring 42, and the other end extends along connecting the casing axial direction, and a plurality of stall posts 43 set up along solid fixed ring 42 circumferential direction equipartition. The inner moving ring 61 is provided with a plurality of mounting rings uniformly distributed in the circumferential direction, each mounting ring is slidably mounted on one of the rotation preventing posts 43, and the inner moving ring 61 is slidably mounted on the plurality of rotation preventing posts 43 only in the axial direction of the connecting housing 41.

When the connecting device works, the connector of the wire 31 on the detection contact 2 is inserted from the fixed ring 42 in the 3-connection locking mechanism 3, and after the insertion, the connecting shell 41 is twisted clockwise, so that the connecting shell 41 drives the inner moving ring 61 to rotate, because the inner rotating ring 63 is fixed on the fixed seat 68, and the inner moving ring 61 can slide on the rotation stopping column 43 on the fixed ring 42, when the connecting shell 41 rotates, the distance between the inner moving ring 61 and the inner rotating ring 63 is continuously close, the inner connecting rods 62 are inclined, the middle parts of the inner connecting rods 62 are continuously close to the axis, and further the first inner hinge shaft 621 is continuously driven to be close to the axis, meanwhile, the second inner hinge shaft 622 adjacent to the first inner hinge shaft is moved away from the axis, and the second inner hinge shaft 622 drives the corresponding inner clamping plate 67 to move towards the axis direction of the 41-connection shell 41 through the arc-shaped trigger rod 66. While the second inner hinge shaft 622 is moved away from the axis of the connection housing 41, the plurality of inner locking plates 67 approach the axis of the connection housing 41 and clamp the connection head of the connection lead 31.

When the second inner hinge shaft 622 moves away from the axis of the connecting housing 41, the trigger plate 65 located outside the second inner hinge shaft 622 expands away from the axis of the connecting housing 41, and the trigger plate 65 rotates in the circumferential direction under the driving of the second inner hinge shaft 622 because the inner locking ring rotates in the circumferential direction in the process of the inclination of the inner connecting rods 62. When the trigger plate 65 is expanded in the direction away from the axis, it contacts the first outer locking plate 56, pushes the first outer locking plate 56 in the direction away from the axis, and rotates relative to the trigger plate 65, so that the first outer hinge shaft 531 moves in the direction away from the axis. The outer link 53 is inclined from a vertical position under the combined influence of the torque of the circumferential rotation of the trigger plate 65 and the direction in which the first hinge shaft is away from the axial center, by the inner rotating ring 63. Because the diameter of the inner locking ring circumference is smaller than the diameter of the outer fastening ring, the variable of the space between the inner connecting rod 62 and the outer connecting rod 53 corresponding to the same rotating angle of the inner locking ring and the outer fastening ring is different, the final inclination angle of the inner connecting rod 62 is larger than the initial inclination angle of the outer connecting rod 53, and the second outer clamping plate 57 is driven to move inwards when the second outer hinge shaft 532 moves inwards, so that the first outer clamping plate 56 and the trigger plate 65 are always in a close-fitting state. Due to the asynchronous expansion of the outer fastening ring and the inner locking ring, the trigger plate 65 slides on the first outer clamping plate 56, thereby causing the inner locking ring to be clamped on the outer fastening ring.

When it is necessary to pull out the connector of the wire 31 from the dead-lock mechanism 3, the unlocking ring 51 is pulled to make the unlocking ring 51 drive the unlocking block 52 to disengage from the unlocking groove on the fixing ring 42, and drive the outer connecting rod 53 to be pulled out of the connecting housing 41, because the outer fastening ring and the inner locking ring are in a locked state, the first outer hinge shaft 531 slides relative to the outer connecting rod 53, and the first outer hinge shaft 531 slides to the lower end of the outer connecting rod 53. The upper end of the outer link 53 is located in the unlocking groove and the outer fastening ring is located at the lower end of the outer link 53, and then the unlocking ring 51 is rotated counterclockwise, so that the inner clamping plate 67 loosens the connection head of the lead 31 in a locked state, and the lead 31 is pulled out from the connection locking mechanism 3.

A method for disassembling and assembling a handheld real-time cardiovascular function intelligent detection module device comprises the following steps:

s1: inserting the connector of the lead 31 of the detection contact from the fixing ring 42 connected with the locking mechanism 3;

s2: the connecting shell 41 is twisted clockwise, so that the connecting shell 41 drives the inner moving ring 61 to rotate, the inner moving ring 61 rotates to drive the inner connecting rod 62 to incline, and then the inner clamping plates 67 are driven to lock the connecting head of the lead 31; meanwhile, the outer fastening ring is driven by the inner locking ring to enable the outer connecting rod 53 to be in a vertical state, and the inner locking ring is clamped by the outer fastening ring;

s3: the unlocking ring 51 is pulled out, the unlocking block 52 is separated from the connecting locking mechanism 3, and the unlocking ring 51 is rotated anticlockwise, so that the locking state of the connecting head of the lead 31 by the inner locking ring is released;

s4: the connection head of the conductor 31 is pulled out of the connection locking mechanism 3.
