[0025] The support assembly 2 includes a sleeve 21 fixed to the upper end of the clamp 1, an insertion rod 22 movably inserted into the sleeve 21, and a positioning pin 23 inserted into the sleeve 21 and the insertion rod 22 to limit the insertion rod 22. The lower end of the support part 3 is rotatably connected to the upper end of the insertion rod 22.

[0026] By adopting the above scheme, the clamp 1 is clamped and fixed on the bedside. After the positioning pin 23 is pulled out, the insertion rod 22 can move up and down inside the sleeve 21 to adjust the height of the support part 3. After the support part 3 is adjusted to a suitable height, the insertion rod 22 is positioned by the positioning pin 23, and the branch head of the lead wire (used to connect the bus (main cable) and the branch wire (each lead wire) of the electrocardiograph lead wire) is clamped between the two limiting flanges 32. Multiple branch wires can pass through the groove 33 and then enter the multiple branch wire grooves 41 respectively after being guided by the buffer arc surface 35. After the multiple branch wires pass through the multiple branch wire grooves 41, they are naturally The lead wires are drooped, and multiple branch wires pass through the branching groove 41 and are then connected to the patch. The lead wires are supported by the support part 3, and the lead wires are located between the two limit plates 31 to realize the storage of the lead wires. The lead wires are in a parallel state on the support part 3 and in a vertical state in the branching groove 41. The lead wires are stored and supported in a horizontal and vertical manner, which can avoid the cracking of the outer insulating material caused by long-term winding of the lead wires or metal fatigue of the internal metal wires due to repeated bending, and the support part 3 can be rotated at the upper end of the insertion rod 22, which can facilitate the movement of the lead wires and make the free end of the lead wires quickly rotate to above the patient's chest.

[0027] See also Figure 2-Figure 4 A movable groove 34 is provided at the upper end of the support part 3, and a wire lifting assembly 5 is connected to the inside of the support part 3. The wire lifting assembly 5 includes a seesaw 54 rotatably connected to the opening of the movable groove 34, a roller 541 rotatably connected to one side of the seesaw 54, two connecting rods 57 symmetrically rotatably connected to one side of the seesaw 54, a rotating rod 55 rotatably connected to the inside of the movable groove 34, and two connecting rods 56 symmetrically fixed to the outside of the rotating rod 55, and the free ends of the two connecting rods 57 are respectively rotatably connected to the free ends of the two connecting rods 56.

At this time, the length of the lead wire hanging down from the branch groove 41 is the longest, and the patch at the free end of the lead wire can also contact the patient's chest. After use, it is necessary to rotate the support part 3 to remove the support part 3 and the lead wire from above the patient's chest. Before rotating the support part 3, move the movable block 51 to separate the movable block 51 from the gear 1 52, rotate the gear 1 52 by the handle 53, and the gear 1 52 rotates clockwise to drive the rotating rod 55 to rotate clockwise. The rotation of the rotating rod 55 can drive the seesaw 54 to rotate clockwise in the movable groove 34 through the connecting rod 1 56 and the connecting rod 2 57, so that the seesaw 54 is provided with a roller 5 One end of 41 is tilted, and in the process of the tilting of the seesaw 54, the roller body 541 can contact the lead wire, and when the seesaw 54 is tilted, the lead wire located on the support part 3 will change from a horizontal state to a bent state. Since the lead wire is bent, the lead wire on the support part 3 can pull the lead wire in the branching groove 41 to move, so that the lead wire in the branching groove 41 moves upward and drives the patch connected to the free end to move upward, so that the distance between the free end of the lead wire and the patient can be increased, and then the support part 3 is rotated to move the support part 3 and the lead wire away from above the patient's chest. Since the free end of the lead wire has risen, the free end of the lead wire and the patch will not contact the patient's body when the lead wire is rotated and stored.

[0030] See also Figure 3 、 Figure 5-Figure 6 The guide portion 4 is provided with a movable groove 2 43 and a through groove 42 connected to the movable groove 2 43, and the guide portion 4 is connected to the wire body moving aid portion 6, the wire body moving aid portion 6 includes two guide rods 65 fixedly connected to the inside of the movable groove 2 43, two springs 66 respectively sleeved on the outside of the two guide rods 65, a seat 64 movably sleeved on the outside of the two guide rods 65 and located in the movable groove 2 43, a plurality of racks 67 fixed on the outer surface of the seat 64, a plurality of racks 67 rotatably connected to the guide portion 4 and respectively connected to the plurality of racks 67.

[0031] The transmission part 69 includes a plurality of gear threes 691 rotatably connected to the inside of the guide part 4 and respectively meshing with the plurality of gear twos 68, a plurality of synchronous wheels one 692 respectively fixed to one side of the plurality of gear threes 691, a plurality of synchronous wheels two 694 respectively fixed to one side of the wheel body two 63, and a synchronous belt 693 connecting the synchronous wheels one 692 and the synchronous wheels two 694.

[0032] The guide portion 4 is also movably connected to a movable seat 61, and a screw 611 is threaded inside the guide portion 4.

[0033] By adopting the above scheme, when the rotating rod 55 rotates clockwise, the wire reel 7 rotates clockwise with the rotating rod 55 and reels the traction line 8, and the traction line 8 pulls the seat body 64 to move upward in the movable groove 2 43. At this time, the spring 66 is compressed, and the seat body 64 moves upward and drives the gear 2 68 to rotate counterclockwise through the rack 67. The gear 2 68 rotates counterclockwise and drives the gear 3 691 and the synchronous wheel 1 692 to rotate clockwise. The synchronous wheel 1 692 drives the synchronous wheel 2 694 and the wheel body 2 63 to rotate clockwise through the synchronous belt 693. The wheel body 2 63 and the lead wire outside the branch groove 41 are connected. Surface contact, and by rotating the screw 611, the movable seat 61 and the wheel body 1 62 can be driven to move toward the lead wire in the branching groove 41, so that the outer surface of the wheel body 1 62 is in contact with the outer surface of the lead wire, the wheel body 1 62 applies pressure to the lead wire and enables the outer surface of the lead wire to be in close contact with the wheel body 1 62 and the wheel body 2 63, thereby increasing the friction force. When the wheel body 2 63 rotates clockwise, it can drive the lead wire to move upward in the branching groove 41, and at the same time, the wheel body 1 62 also rotates, so that the lead wire in the branching groove 41 can be transported, so that the lead wire can move more smoothly in the branching groove 41.
