Detailed implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] The present invention provides a Figure 1-7 sequential titanium clip under colonoscopy as shown, including a sleeve 11, a titanium clip assembly, a connecting mechanism and a moving mechanism. An activity groove 12 is provided inside the sleeve 11, and a movable rod 13 is inserted inside the activity groove 12;

[0032] There are multiple titanium clip assemblies, and the multiple titanium clip assemblies are arranged at intervals inside the activity groove 12. The connecting mechanism is arranged between the movable rod 13 and the titanium clip assembly. The moving mechanism is arranged on the outer wall of the sleeve 11, and the moving mechanism is connected to the movable rod 13. The movable rod 13 is connected to the titanium clip assembly through the connecting mechanism, and then the corresponding titanium clip assembly is driven to move through the operation of the moving mechanism for work;

[0033] The titanium clip assembly includes a first titanium clip 21 and a second titanium clip 22. The first titanium clip 21 and the second titanium clip 22 are in a horizontal state inside the activity groove 12, which is convenient for the titanium clip assembly to move inside the activity groove 12. There are two sets of rotating mechanisms between the first titanium clip 21 and the second titanium clip 22. The first titanium clip 21 and the second titanium clip 22 are connected through the rotating mechanism. There are two sets of elastic mechanisms between the first titanium clip 21 and the second titanium clip 22. Through the elastic mechanism, the first titanium clip 21 and the second titanium clip 22 can be clamped for work. At the same time, the setting of the two sets of rotating mechanisms enables the movable rod 13 to pass through the titanium clip assembly without being affected;

[0034] The rotating mechanism includes a first connecting piece 23 and a second connecting piece 24. The first connecting piece 23 is fixedly connected to the bottom end of the first titanium clip 21, and the second connecting piece 24 is fixedly connected to the top end of the second titanium clip 22. Rotation holes 25 are formed on one side of both the first connecting piece 23 and the second connecting piece 24. A rotating rod 26 is rotatably connected to the inner walls of the two rotation holes 25, enabling the first titanium clip 21 and the second titanium clip 22 to rotate around the rotating rod 26 for working;

[0035] The elastic mechanism includes a torsion spring 27. The torsion spring 27 is sleeved on the outer wall of the rotating rod 26. One end of the torsion spring 27 is in contact with the bottom end of the first titanium clip 21, and the other end of the torsion spring 27 is in contact with the top end of the second titanium clip 22. Through the elastic action of the torsion spring 27, the titanium clip assembly can work stably when the first titanium clip 21 and the second titanium clip 22 are not under external force;

[0036] Limit pieces 28 are fixedly connected to both ends of the rotating rod 26. The diameter of the limit pieces 28 is larger than the inner diameter of the rotation holes 25. Through the limitation of the limit pieces 28 by the rotation holes 25, the rotating rod 26 will not separate from the rotation holes 25, thereby improving the stability of the use of the rotating rod 26 and enabling the titanium clip assembly to be used stably;

[0037] The connecting mechanism includes a connecting head 31 and two fixing blocks 32. The connecting head 31 is arranged at one end of the movable rod 13. One of the fixing blocks 32 is fixedly connected to the bottom end of the first titanium clip 21, and the other fixing block 32 is fixedly connected to the top end of the second titanium clip 22. First moving holes 33 are formed at the top and bottom of the connecting head 31. First connecting blocks 35 are movably inserted through the inner walls of the two first moving holes 33. Placing holes 34 are formed on the opposite sides of the two fixing blocks 32. The outer walls of the two first connecting blocks 35 are movably inserted through the inner walls of the two placing holes 34 respectively. By inserting the two first connecting blocks 35 into the corresponding placing holes 34, the placing holes 34 can limit the first connecting blocks 35, so that when the connecting head 31 moves, it can drive the titanium clip assembly to move, and thus the titanium clip assembly can be pushed out of the sleeve 11 for working;

[0038] The inner wall of the placement hole 34 is fixedly connected to the second connecting block 36. The second connecting block 36 is an iron block, and the first connecting block 35 is a magnet block, so that the first connecting block 35 and the second connecting block 36 can be adsorbed together. A first moving cavity 41 is opened inside the connecting head 31. The first moving cavity 41 communicates with the two first moving holes 33 respectively. Two first limiting plates 42 are slidably connected to the inner wall of the first moving cavity 41. The two first connecting blocks 35 are respectively connected to the two first limiting plates 42. The outer walls of the two first connecting blocks 35 are both sleeved with first springs 43. One end of the connecting head 31 is provided with a first semi-circular head, and the other end of the connecting head 31 is provided with a second semi-circular head. Arc chamfers are opened at the ends of the two first connecting blocks 35. After the previous titanium clip assembly is pushed out, move the connecting head 31 backward so that the connecting head 31 is inserted between the two fixing blocks 32 until the first connecting block 35 is aligned with the first connecting block 35. Under the action of magnetic force, the first connecting block 35 pops out outward and can be inserted into the corresponding placement hole 34 and adsorbed to the corresponding second connecting block 36. Then, by moving the connecting head 31, the connected titanium clip assembly can be driven to move. Through the settings of the first semi-circular head and the second semi-circular head, it is convenient for the connecting head 31 to move between the two fixing blocks 32. At the same time, the setting of the arc chamfer is convenient for the first connecting block 35 to be inserted into the placement hole 34, but the arc chamfer does not affect the limitation of the placement hole 34 on the first connecting block 35, so that the titanium clip assembly can move stably. The elastic force of the torsion spring 27 can overcome the magnetic force between the first connecting block 35 and the second connecting block 36. At the same time, the magnetic force between the first connecting block 35 and the second connecting block 36 can overcome the elastic force of the first spring 43. And two stop blocks are fixedly connected inside the first moving cavity 41. After the first connecting block 35 is no longer connected to the second connecting block 36, under the elastic action of the first spring 43, the two first limiting plates 42 move relatively, so that the two first connecting blocks 35 can retract into the first moving holes 33, so that the connecting head 31 can be smoothly inserted between the two fixing blocks 32 of the next titanium clip assembly. The overall connection mechanism is similar to the fixing method of the dial and the strap of a current smart watch;

[0039] The moving mechanism includes a sliding sleeve 53. The sliding sleeve 53 is sleeved on the sleeve 11. A sliding groove 51 is opened on the outer wall of the sleeve 11. A sliding rod 52 is slidably connected to the inner wall of the sliding groove 51. The sliding rod 52 is fixedly connected to the other end of the movable rod 13. Connecting rings 54 are fixedly connected to the top and bottom of the outer wall of the sliding sleeve 53. One end of the sleeve 11 is fixedly connected to the push-pull plate 55. By connecting the movable rod 13 with the sliding sleeve 53 through the sliding rod 52, the movable rod 13 can be controlled through the sliding sleeve 53 outside the sleeve 11, improving the convenience of operating the movable rod 13. It is convenient to move the sliding sleeve 53 through the two connecting rings 54, and it is convenient to move the sleeve 11 through the push-pull plate 55;

[0040] Two threaded holes 61 are formed in the outer wall of the sliding sleeve 53. Locking bolts 62 are threadedly connected to the inner walls of the two threaded holes 61. By tightening the locking bolts 62 in the threaded holes 61 to abut against the outer wall of the sleeve 11, the sliding sleeve 53 can be positioned outside the sleeve 11, thereby preventing the automatic movement of the moving mechanism;

[0041] One end of the connector 31 is provided with a jack 77. One end of the movable rod 13 is movably inserted into the outer wall of the jack 77. A second movable cavity 71 is formed inside the movable rod 13. Second movable holes 72 are formed at the top and bottom of the inner wall of the second movable cavity 71. Positioning rods 73 are movably inserted into the inner walls of the two second movable holes 72. Two second limiting plates 75 are slidably connected to the inner wall of the second movable cavity 71. The two positioning rods 73 are respectively connected to the two second limiting plates 75. Positioning holes 74 are formed at the top and bottom of the inner wall of the jack 77. The two positioning rods 73 are respectively movably inserted into the inner walls of the two positioning holes 74. A second spring 76 is arranged between the two second limiting plates 75. Due to the elastic action of the second spring 76, the two positioning rods 73 are ejected outward and inserted into the positioning holes 74. At this time, the positioning rods 73 are limited by the positioning holes 74, so that the movable rod 13 is connected to the connector 31. At the same time, the second movable holes 72 limit the second limiting plates 75, preventing the positioning rods 73 from separating from the second movable cavity 71, and improving the stability of the positioning rods 73 during use.

[0042] The working principle of the present invention:

[0043] When the titanium clip assembly needs to be used, when the sleeve 11 is inserted into the corresponding position, then loosen the locking bolt 62 so that the locking bolt 62 no longer abuts against the sleeve 11. At this time, the two connecting rings 54 can be moved. The movement of the two connecting rings 54 drives the movement of the sliding sleeve 53. The movement of the sliding sleeve 53 drives the movement of the sliding rod 52. The movement of the sliding rod 52 drives the movement of the movable rod 13. The movement of the movable rod 13 drives the movement of the connecting head 31. Through the limitation of the first connecting block 35 by the placing hole 34, the movement of the connecting head 31 drives the movement of the two fixing blocks 32. The movement of the two fixing blocks 32 can drive the movement of the connected first titanium clip piece 21 and the second titanium clip piece 22 until the first titanium clip piece 21 and the second titanium clip piece 22 are pushed out of the sleeve 11. At this time, under the elastic action of the torsion spring 27, the pushed-out titanium clip assembly is clamped to work. Due to the clamping of the first titanium clip piece 21 and the second titanium clip piece 22, the first connecting block 35 is separated from the second connecting block 36. At this time, under the elastic action of the first spring 43, the two first limiting plates 42 move relatively, so that the two first connecting blocks 35 can respectively contract into the corresponding first movable holes 33. Then pull back the sliding sleeve 53 until the connecting head 31 moves between the two fixing blocks 32 of the next titanium clip assembly until the first connecting block 35 is aligned with the corresponding second connecting block 36. At this time, under the magnetic force between the first connecting block 35 and the second connecting block 36, the first connecting block 35 overcomes the elastic force of the first spring 43 and pops out to adsorb with the second connecting block 36. At this time, the connecting head 31 can be pushed to push out the corresponding titanium clip assembly for use;

[0044] When the titanium clip assembly in the sleeve 11 is completely pushed out, at this time, push the connecting head 31 to expose the connecting head 31 from the sleeve 11, and then press the two positioning rods 73. The two positioning rods 73 drive the relative movement of the two second limiting plates 75 until the two positioning rods 73 are separated from the corresponding positioning holes 74. At this time, the connecting head 31 can be removed, and the connecting head 31 is separated from the movable rod 13. Then the unused titanium clip assembly can be pushed into the sleeve 11. After multiple titanium clip assemblies are clamped, the connecting head 31 can be connected to the movable rod 13 again.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
