The driving motor 13 rotates the rotating rod 11, and the rotating rod 11 rotates to move around the stretching wire 12 arranged on the rotating rod 11, so as to drive the moving ring 5 to ascend or descend on the surface of the sliding rod 3, when the tower-shaped spring ring 7 is stretched, the stretching wire 12 should be in a straight state under the action of the tower-shaped spring ring 7.
In this technical solution, a controller (not shown in the figure) should be disposed outside the human body, the controller is electrically connected to the driving motor 13, and the controller is used to control the start and the pause of the driving motor 13, so as to control the movement of the moving ring 5.
Further optimizing scheme, the holder includes first connecting rod 14 and second connecting rod 15 that relative setting, first connecting rod 14 and second connecting rod 15 all are located recess 6, first connecting rod 14 is located the one side that slide bar 3 was kept away from to second connecting rod 15, and first connecting rod 14 and second connecting rod 15 both ends all with the rigid coupling of motion ring 5, the rigid coupling has first lantern ring 141 on first connecting rod 14, first lantern ring 141 bottom rigid coupling has first splint 142, be connected with second lantern ring 151 through rotating the piece rotation on the second connecting rod 15, second lantern ring 151 bottom rigid coupling has second splint 152, the biggest end of tower type spring ring 7 diameter is located between first splint 142 and the second splint 152, and tower type spring ring 7 one end and first splint 142 and second splint 152 butt, slide bar 3 lateral wall rigid coupling has wedge 16, wedge 16 and the sliding contact of rotating the piece. Under the action of the first clamping plate 142 and the second clamping plate 152, the tower-type spring ring 7 is clamped between the first clamping plate 142 and the second clamping plate 152, and due to the existence of the rotating member, the second sleeve ring 151 can rotate relative to the second connecting rod 15, so as to control the movement of the second clamping plate 152, control the position relation between the second clamping plate 152 and the first clamping plate 142, and further control the connection relation between the tower-type spring ring 7 and the moving ring 5.
In a further optimized scheme, the rotating member comprises a second stopper 153 fixedly connected with the top end of the second collar 151, the top end of the first collar 141 is fixedly connected with a first stopper 143, a compression spring 20 is arranged between the first stopper 143 and the second stopper 153, two ends of the compression spring 20 are fixedly connected with the first stopper 143 and the second stopper 153 respectively, and one side, far away from the compression spring 20, of the second stopper 153 is in sliding contact with the wedge 16. In the process of clamping the tower-type spring ring 7, the compression spring 20 should be in a compressed state, so that the second stopper 153 is forced away from the first stopper 143, and under the action of the first collar 141, the second clamping plate 152 and the first clamping plate 142 are engaged to complete the clamping of the tower-type spring ring 7. The wedge 16 exists, when the moving ring 5 moves downwards, and the second stopper 153 is in contact with the wedge 16, the wedge 16 blocks the second stopper 153, so that the second stopper 153 moves towards the direction close to the first stopper 143, and the second clamp 152 moves towards the direction far away from the first clamp 142, at this time, the tower-shaped spring ring 7 still has certain elasticity, and therefore the tower-shaped spring ring can be separated from the first clamp 142 and the second clamp 152, and the separation of the subsequent slide bar 3 and the tower-shaped spring ring 7 is facilitated. And because the tower-shaped spring ring 7 is when separating with the motion ring 5, the reduction of tower-shaped spring ring 7 elasticity makes tower-shaped spring ring 7 reduce the vibration, and then is difficult to make tower-shaped spring ring 7 because the vibration causes too big skew to the accuracy nature of release has been improved.
According to the further optimization scheme, a plurality of sliding grooves 17 are formed in the circumferential direction of the outer side wall of the sliding rod 3, the limiting part comprises a limiting block 18 fixedly connected with the inner wall of the moving ring 5, the limiting block 18 is matched with the sliding grooves 17, the wedge block 16 is located in the sliding grooves 17, and the wedge block 16 is located below the limiting block 18. The side wall of the sliding rod 3 is provided with a sliding groove 17, the limiting block 18 is positioned in the sliding groove 17, and the limiting block 18 is matched with the sliding groove 17, so that the moving ring 5 cannot rotate relative to the sliding rod 3, and the tower-shaped spring ring 7 is not easy to deform. The wedge block 16 is positioned in the sliding groove 17, so that the influence on the tower-shaped spring ring 7 can be reduced, and the tower-shaped spring ring 7 can be normally stretched and restored to the initial state.
In this technical solution, a through groove 21 is formed in the groove 6, and the second stopper 153 is in surface sliding contact with the wedge 16 through the through groove 21. The purpose of the through slot 21 is to facilitate the contact of the second stop 153 with the wedge 16, the through slot 21 preferably opening at the bottom end of the moving ring 5, the through slot 21 being a through slot so that the second stop 153 can pass through the through slot 21 to contact the wedge 16.
In a further optimized scheme, the diameter of one end, far away from the sliding rod 3, of the supporting column 4 is smaller than that of one end, close to the sliding rod 3, of the supporting column 4. Support column 4 is a round platform type structure, embolias the less one end of spacing ring 8 by support column 4 diameter, treat that spacing ring 8 removes one end distance after, because support column 4's diameter grow to block spacing ring 8, make spacing ring 8 can not continue to move, and then can realize the tensile to tower type spring coil 7, and when releasing tower type spring coil 7, support column 4's structure setting makes tower type spring coil 7 be convenient for separate with support column 4.
In a further optimized scheme, a plurality of cilia 19 are fixedly connected to the outer side of the maximum diameter circle of the tower-shaped spring ring 7. The length of the tower-shaped spring coil 7 is short in the original state, the diameter of the tower-shaped spring coil 7 can be large, in order to prevent air leakage, a plurality of cilia 19 can be arranged on the tower-shaped spring coil 7, and the number and the position of the cilia 19 can be determined according to the actual use condition, so that the sealing effect is preferably improved.
Among this technical scheme, the biggest circle outside rigid coupling of tower type spring coil 7 diameter has a plurality of barbs 22, because tower type spring coil 7 position relation for tower type spring coil 7 is coughed easily, consequently sets up barb 22 on tower type spring coil 7's surface, makes barb 22 and the contact of organizing on every side. And the setting of barb 22 for callus such as granulation that produce during the healing is connected with tower type spring coil 7 easily, and then fixes tower type spring coil 7's position, and barb 22 only need set up 7 diameter of tower type spring coil outside the biggest circle can, so that fix tower type spring coil 7.
In a further optimized scheme, the length of the cilia 19 is 3-6 mm, and the cilia 19 is made of nylon. The length of cilia 19 sets up according to the in-service use condition, and its length is between 3mm ~ 6mm, and adopts the nylon material because the nylon material is comparatively soft, and not fragile, can effectively prevent to continue gas leakage.
In a further optimized scheme, the limiting ring 8 is made of opaque materials. The stop collar 8 adopts light-tight material because tower spring ring 7 needs the location when releasing, and light-tight material indicates the material of opaque X-ray, shines through the outside and demonstrates the position of stop collar 8, and the position of stop collar 8 is the final release position of tower spring ring 7 promptly, through the position of adjusting stop collar 8, can be comparatively accurate release tower spring ring 7.
In a further optimized scheme, the tower-shaped spring ring 7 is made of shape memory alloy.
