[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1:

[0041] like Figures 1 to 3 As shown, the utility model provides an adjustable bracket for an external diaphragm pacemaker, comprising a support plate 1, and a slide bar 2, a fixed rotating wheel assembly 3 and a movable rotating wheel assembly 4 mounted on the support plate 1.

[0042] The upper portion of the support plate 1 has an inclined mounting surface 11. The fixed wheel assembly 3 includes a fixed support block 31 fixed to the upper edge of the support plate 1. Two slide bars 2 are arranged on both sides of the mounting surface 11 and are parallel to each other; the upper end of the slide bar 2 is fixed on the fixed support block 31, and the lower end of the slide bar 2 is fixed on the positioning seat 21, and the positioning seat 21 is fixed to the lower edge of the mounting surface 11. The movable wheel assembly 4 includes a movable support block 41, which is parallel to the fixed support block 31; through holes are provided at both ends of the movable support block 41, and linear bearings 42 are fixedly installed in the through holes; the linear bearings 42 on both sides are slidably installed on the corresponding slide bars 2. Under the action of the linear bearings 42 on both sides, the movable support block 41 can slide along the slide bar 2 toward or away from the fixed support block 31. A fastening bolt 43 is threadedly connected to the dynamic support block 41 , and the inner end of the fastening bolt 43 abuts against the mounting surface 11 of the support plate 1 . The fastening bolt 43 can realize unlocking and positioning between the dynamic support block 41 and the support plate 1 .

[0043] Recombination Figures 4 to 6 As shown, a row of running wheels 5 are rotatably mounted on both the fixed running wheel assembly 3 and the movable running wheel assembly 4. A wire pressing plate 7 is provided on one side of the running wheel 5 for use with the running wheel 5. The running wheel 5 and the wire pressing plate 7 on the movable running wheel assembly 4 are used as an example for explanation:

[0044] The runner 5 is rotatably mounted on the upper surface of the movable support block 41, and an arc-shaped wire groove 51 for placing the wire 6 is provided on the circumferential surface of the runner 5. The wire pressing plate 7 is located on the side of the movable support block 41 away from the fixed runner assembly 3. The cross-section of the wire pressing plate 7 is "L"-shaped, and the side of the wire pressing plate 7 has a positioning groove 71 that cooperates with the movable support block 41. The wire pressing plate 7 is fixed to one side of the movable support block 41 by bolts. The wire pressing plate 7 is snapped onto one side of the runner 5, and a gap is formed between the wire pressing plate 7 and the runner 5 for the wire 6 to pass through. The edge of the wire pressing plate 7 positions the wire 6 in the arc-shaped wire groove 51 to prevent the wire 6 from escaping from the arc-shaped wire groove 51.

[0045] like Figure 1and Figure 2 As shown, a wire 6 is wound around the wheels 5 of the fixed and movable wheel assemblies 3 and 4, respectively. One end of the wire 6 has a plug 61 for connecting to the host computer, and the other end of the wire 6 has a silicone electrode 62. One end of the plug 61 of the wire 6 is fixed to the fixed and movable wheel assemblies 3 by a pressure strip 63 to prevent the plug 61 from being dragged.

[0046] Example 2:

[0047] Based on the above embodiment 1, combined with Figure 1 、 Figure 4 and Figure 5 As shown, both ends of the fixed support block 31 are fixed to the mounting surface 11 via connecting seats 32. The connecting seat 32 is in a "Z" shape, with the upper end of the connecting seat 32 fixedly connected to the end face of the fixed support block 31 by bolts, and the lower end of the connecting seat 32 fixedly connected to the side end of the mounting surface 11 by bolts. The upper end of the connecting seat 32 has a stop, and the end of the fixed support block 31 is positioned on the stop, so that there is a gap of a certain height between the bottom surface of the fixed support block 31 and the mounting surface 11. Similarly, there is also a gap of a certain height between the bottom surface of the dynamic support block 41 and the mounting surface 11, so that the dynamic support block 41 can slide smoothly along the slide rod 2.

[0048] Example 3:

[0049] Based on the above embodiment 1, combined with Figures 1 to 3 As shown, the lower portion of the support plate 1 has a support surface 12 with two parallel elongated holes 13 defined therein. The support surface 12 and the mounting surface 11 are integrally formed, with a 30° angle between them. During use, the support surface 12 is mounted vertically on one side of the main unit, while the mounting surface 11 is tilted to facilitate operation of the movable support block 41 thereon.

[0050] When using, Figure 2 As shown, first loosen the fastening bolt 43 to unlock the movable support block 41; then pull one end of the silicone electrode 62 of the wire 6. At this time, the wire 6 moves around the various wheels 5 on the fixed support block 31 and the movable support block 41, thereby pulling the lower movable support block 41 upward along the slide bar 2; finally, connect one end of the silicone electrode 62 to the patient's body, and relock the movable support block 41 by fastening the bolt 43;

[0051] After use, first loosen the fastening bolt 43 to unlock the dynamic support block 41; then push the dynamic support block 41 downward, and the wire 6 retracts back between the dynamic support block 41 and the fixed support block 31, and finally relock the dynamic support block 41 by fastening the bolt 43.

[0052] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
