A cross sliding groove is formed in the observation block 12, the sliding block 23 is arranged in the cross sliding groove, the clamping piece 22 is installed on the sliding block 23, the threaded ring 21 is sleeved on the A electrode lead 13, and the threaded ring 21 is threadedly arranged on the clamping piece 22. Two mounting assemblies 2 are arranged, and the two mounting assemblies 2 are arranged on the A electrode lead 13 and the B electrode lead 14 respectively.

[0028] Specifically, when installing the pacemaker assembly 1, a pouch is made under the patient's skin, and then the A electrode wire 13 and the B electrode wire 14 are delivered to the patient's myocardial tissue through the pouch. The pacemaker body 11 and the observation block 12 are set in the pouch band to prevent the pacemaker assembly 1 from being separated from the patient during subsequent use. During installation, since the A electrode wire 13, the B electrode wire 14 and the pacemaker body 11 and the observation block 12 are installed separately, the A electrode wire 13, the B electrode wire 14 and the observation block 12 need to be assembled after installation. During this period, a clamping part 22 can be set on both the A electrode wire 13 and the B electrode wire 14, and a sliding block 23 can be set on the clamping part 22, and a threaded ring 21 can be threadedly set on the surface of the clamping part 22. The threaded ring 21 can make the clamping part 22 move inward, and then the A electrode wire 13 and the B electrode wire 14 can be clamped, so that the A electrode wire 13 and the B electrode wire 14 can be stably connected to the observation block 12.

[0029] In this embodiment, the clamping member 22 includes a clamping portion 221 and a threaded portion 222 . A plurality of clamping portions 221 are provided, and the plurality of clamping portions 221 are arranged in a circular array. The threaded portion 222 is provided on the plurality of clamping portions 221 .

[0030] Specifically, when in use, the A electrode wire 13 or the B electrode wire 14 is wrapped by the four clamping parts 221, and the threaded parts 222 are set on the surfaces of the four clamping parts 221. The four clamping parts 221 can be threadedly connected to the threaded ring 21 through the threaded parts 222.
