The distance between the position slots 311 increases, and at this time, the rotating base 5 and the clamping block 6 are on the same parallel line as the position of the movable rod 3 drops. The rotating plate 51 is rotated into the slot 61, the upper and lower side walls of the rotating base 5 are both provided with grooves, and a rotating pin is rotated in the two grooves. When the rotating plate 51 is moved, the human hand no longer presses the pressing plate 4, so that when the spring 401 in the fixed seat 42 rebounds, the rotating plate 51 is driven to contact the inner wall of the card slot 61, and the limit of the movable rod 3 will not be Continue to move to stabilize the distance between the two limit slots 311 (as shown in Figure 4 in the accompanying drawings), at this time, the medical staff can pass the pacing electrode wire from between the two limit slots 311 into the The tube sheath group 1, and then the rotating plate 51 will be rotated to the original position again by the human hand, and it is not located in the clamping slot 61. At this time, the movable rod 3 is no longer limited by the cooperation of the rotating plate 51 and the clamping slot 61, and the spring 401 The rebound force when it is no longer under the pressure of the hand, drives the movable rod 3 to move upward, so that the limit plate 31 at the bottom of the movable rod 3 moves with the movement of the movable rod 3, and the pacing electrode wire is clamped to the installation block by the elastic force of the spring 401 2. The pacing electrode wire is fixed in the limit groove 311 opened by the limit plate 31, and the operation steps are simple, which improves the efficiency and convenience when temporarily fixing the pacing electrode wire. After completion, the elastic connecting block 11 is pulled out from the connecting groove 21 to disassemble the mounting block 2, which is reserved for the next use, which saves the use cost.

In FIGS. 1 and 2 : the upper end surface of the limiting plate 31 and the inner wall of the upper end of the mounting block 2 are provided with matching limiting grooves 311 ; After the movable rod 3 is passed, the limit of the movable rod 3 by the rotating plate 51 and the card slot 61 is released, so that the spring 401 rebounds and drives the limit plate 31 to rise, and passes through the two limit plates between the limit plate 31 and the installation block 2. The grooves 311 limit and fix the pacing electrode wires.

In Fig. 1: one side wall of the tube sheath group 1 is fixedly connected with two symmetrically distributed elastic connecting blocks 11, one side wall of the installation block 2 is provided with two symmetrically distributed connecting grooves 21, and the tube sheath group 1 is provided with two symmetrically distributed connecting grooves 21. The elastic connecting block 11 is matched with the connecting groove 21 to complete the clamping and fixing with the mounting block 2; the elastic connecting block 11 is made of rubber, and the elastic connecting block 11 of the tube sheath group 1 is pressed and inserted into the mounting block 2 before use. In the opened connection groove 21 , the elastic connection block 11 is locked and limited by the connection groove 21 , and the installation between the tube sheath group 1 and the installation block 2 is completed.

In FIGS. 3 and 4 : one side of the inner wall of the fixed seat 42 is fixedly connected with a spring 401 , the other end of the spring 401 is fixedly connected with the sliding rod 41 , and one side wall of the clamping block 6 is provided with a clamping plate that matches the rotating plate 51 . Slot 61, after pressing down the pressing plate 4 to make the movable rod 3 descend at the elastic position of the spring 401, manually move the rotating plate 51 into the clamping slot 61, so that the movable rod 3 is limited by the rotating plate 51 and the clamping slot 61 , the movable rod 3 will not return to its original position due to the rebound of the spring 401 without continuing to press down the pressing plate 4, so that the distance between the limit plate 31 at the bottom of the movable rod 3 and the inner wall of the mounting block 2 is stable, that is, Threading of the pacing lead can begin.

The working principle and use process of the utility model: before use, the elastic connecting block 11 of the tube sheath group 1 is pressed and inserted into the connecting groove 21 opened by the installation block 2, so that the elastic connecting block 11 is limited by the engaging groove of the connecting groove 21. Position, complete the installation between the sheath group 1 and the installation block 2, when the pacing electrode wire is used, the human hand presses the pressing plate 4, so that the spring 401 at the bottom of the slide bar 41 is elastically contracted by the pressure of the human hand, and drives the slide bar 41 enters the fixed seat 42, at this time, the movable rod 3 at the bottom of the pressing plate 4 is pressed down by the human hand and slides down, so that the distance between the limit plate 31 and the limit groove 311 opened by the installation block 2 increases, and at this time The rotating base 5 is on the same parallel line with the clamping block 6 as the position of the movable rod 3 drops. At this time, the manual turns the rotating plate 51 on one side of the rotating base 5 to rotate the rotating plate 51 into the clamping slot 61. At this time, the manual The pressing plate 4 is no longer pressed, so that when the spring 401 in the fixed seat 42 rebounds, the rotating plate 51 is brought into contact with the inner wall of the card slot 61, and the movable rod 3 is limited and will not continue to move, so that the two limit grooves 311 are separated from each other. The distance between them is stable, at this time, the medical staff can pass the pacing electrode wire from between the two limit slots 311 into the sheath group 1, and then turn the rotating plate 51 to the original position again by hand, and it is not located in the card. In the groove 61, the movable rod 3 at this time is no longer limited by the cooperation of the rotating plate 51 and the card slot 61, and the elastic force of the spring 401 when it is no longer subjected to the pressure of the hand, drives the movable rod 3 to move upward, so that the bottom of the movable rod 3 is moved upward. With the movement of the movable rod 3, the limit plate 31 of the pacing electrode is clamped in the limit groove 311 opened by the mounting block 2 and the limit plate 31 through the elastic force of the spring 401 to complete the fixation of the pacing electrode line. The operation steps are concise, which improves the efficiency and convenience when temporarily fixing the pacing electrode wire, and after the tube sheath group 1 is used, the elastic connecting block 11 is pulled out from the connecting groove 21 to disassemble the mounting block 2. Reserve for the next use, saving the cost of use.
