Description

Technical Field

[0001] This invention relates to the field of interventional surgical instruments, and in particular to a moving wheel assembly, a pushing assembly, a drive box, and a control system for interventional surgical instruments. Background Technology

[0002] In related technologies, patients requiring interventional surgery are first guided by a physician through vascular puncture to insert a sheath into a specific surgical vessel (establishing the internal and external access points for interventional treatment). Then, through the sheath, a catheter or guidewire is inserted to locate the specific lesion, followed by treatment or stent placement. A Y-valve is connected to the end of the catheter to facilitate the injection of fluids for examination or treatment, such as contrast fluid. Currently, interventional surgical actuators have been used to some extent in interventional procedures, but some shortcomings remain. For example, the advancement of catheters or long, thin objects is inconvenient, and slippage can easily occur during advancement, affecting the surgical outcome. Summary of the Invention

Detailed Implementation

[0045] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0046] It should be noted that, Figure 4Second elastic element 36 Figure 6 and Figure 11 The diagram illustrates the front, back, left, and right directions, and shows the positions of the moving wheel assembly 3a, fixed wheel assembly 3b, and drive box 100 as shown. This arrangement is for ease of explanation of the embodiment. In practical applications, the moving wheel assembly 3a, fixed wheel assembly 3b, and drive box 100 do not necessarily need to be arranged in the directions shown in the diagram; they can be set according to actual needs. Therefore, the orientation of these components does not limit the scope of protection of this embodiment. The horizontal direction referred to laterally is the left-right direction shown in the diagram, and the vertical direction is the direction perpendicular to the horizontal plane, which is determined by the front-back and left-right directions.

[0047] Combination Figure 1 and Figure 3 According to an embodiment of the present invention, the moving wheel assembly 3a includes: a first mounting base 31, a mounting frame 34, and a moving wheel 316. The first mounting base 31 has an accommodating space and includes a first baffle 311, a second baffle 312, and a bottom baffle 314. The accommodating space is at least surrounded by the first baffle 311, the second baffle 312, and the bottom baffle 314 of the first mounting base 31. The first baffle 311 and the second baffle 312 are laterally opposite each other. The mounting frame 34 is movably disposed within the accommodating space and is restricted to move between the first baffle 311 and the second baffle 312. The moving wheel 316 is rotatably mounted on the mounting frame 34 and can protrude from the second baffle 312 to be suitable for contact with other objects. The first baffle 311 and the bottom baffle 314 are both provided with openings and communicate to form a first mounting opening 310a. The first mounting opening 310a is configured to allow the mounting frame 34 to pass through and be inserted into the accommodating space. Specifically, the accommodating space of the first mounting base 31 can be used to accommodate the mounting frame 34 and the moving wheel 316. The mounting frame 34 is used to install the moving wheel 316, so that the moving wheel 316 can be rotatably mounted on the first mounting base 31, and the moving wheel 316 can move with the movement of the mounting frame 34.

[0048] It should be noted that the mounting bracket 34 is restricted to move between the first baffle 311 and the second baffle 312. This means that the first baffle 311 and the second baffle 312 restrict the extreme position of the lateral movement of the mounting bracket 34. In other words, the overall structure of the mounting bracket 34 itself does not necessarily have to be entirely restricted between the first baffle 311 and the second baffle 312.

[0049] Combination Figure 2 and Figure 3 During assembly, the mounting bracket 34 can be directly inserted into the accommodating space of the first mounting base 31 from the first mounting port 310a, which helps to simplify the structure inside the drive wheel assembly 3a, facilitates assembly, and ensures high stability.

[0050] According to an embodiment of the present invention, the moving wheel assembly 3a, by providing a mounting bracket 34 that can move between the first baffle 311 and the second baffle 312, facilitates the installation of the moving wheel 316 and improves the stability of the installation of the moving wheel 316, making the moving wheel 316 movable in the lateral direction, thereby improving the functionality of the moving wheel assembly 3a.

[0051] In practical applications, when the moving wheel assembly 3a is used in the control system of interventional surgical instruments, the moving wheel 316 can cooperate with the fixed wheel 321 to clamp or release the elongated object 9 during the lateral movement of the moving wheel 316. Specifically, the moving wheel 316 can improve stability when clamping the elongated object 9, and can rotate when pushing the elongated object 9 to improve the pushing effect; the moving wheel 316 can release the elongated object 9 when moving towards the second baffle 312, so as to facilitate the removal of the elongated object 9 and provide convenience for the user. The elongated object 9 can be a guide wire for a catheter, guide wire, or treatment stent.

[0052] Combination Figure 1 and Figure 5 Optionally, the drive wheel assembly 3a further includes a first elastic element 35 disposed within the accommodating space. A first guide hole 340 is provided on the mounting bracket 34, and a second guide hole (not shown in the figure) is provided on the first baffle 311. One end of the first elastic element 35 abuts against the bottom of the first guide hole 340, and the second end abuts against the bottom of the second guide hole. By providing the first elastic element 35, the drive wheel 316 can compress its wheel surface contact element, and the first elastic element 35 can also provide a buffering force to prevent damage to the contact element, thus providing protection. The first elastic element 35 can provide tension between the first mounting base 31 and the mounting bracket 34, and the guide hole has a positioning and guiding function. Specifically, when the wheel surface of the drive wheel 316 is under pressure, the mounting bracket 34 moves towards the first baffle 311, and the first elastic element 35 is compressed. When the pressure disappears, the first elastic element 35 releases the compressed elastic force, pushing the mounting bracket 34 towards the second baffle 312.

[0053] The first guide hole 340 and the second guide hole can provide a limiting effect when the first elastic element 35 is installed. During installation, the first end and the second end of the first elastic element 35 are pressed against the bottom of the first guide hole 340 and the second guide hole, respectively, which helps to improve assembly efficiency and connection stability. Figure 5 The guide hole can have a certain depth to improve the limiting effect and make it difficult for the first elastic element 35 to come out of the guide hole during operation.

[0054] Optionally, the drive wheel assembly 3a further includes: a first elastic member 35 disposed within the accommodating space, one end of the first elastic member 35 abutting against the first baffle 311 and the other end abutting against the mounting bracket 34; a first mounting opening 310a allows the first elastic member 35 to pass through and be inserted between the first baffle 311 and the mounting bracket 34 for assembly purposes. In conjunction with the foregoing, when installing the first elastic member 35, it can be positioned in the first guide hole 340 and the second guide hole, thereby improving assembly efficiency and stability.

[0055] Optionally, the second baffle 312 is provided with a second mounting port 310b, and the mounting bracket 34 has a third mounting port 307; the second mounting port 310b and the third mounting port 307 are opposite to each other so that the moving wheel 316 can be inserted between the top plate 343 and the bottom plate 344 of the mounting bracket 34, which is beneficial to improve space utilization, and protrudes from the second mounting port 310b and the third mounting port 307 so that the wheel surface of the moving wheel 316 can contact the contacting object.

[0056] Combination Figure 5 Optionally, both the top plate 343 and the bottom plate 344 are provided with bosses 341. The top surface of the bosses 341 is opposite to the end face of the bearing 306 of the moving wheel 316. This can reduce the surface machining accuracy of the bottom plate 344 and reduce the machining cost. Alternatively, it can also play a certain positioning role, which is conducive to improving the stability of the connection between the mounting bracket 34 and the moving wheel 316.

[0057] Combination Figure 3 , Figure 4 and Figure 5 Optionally, the mounting bracket 34 is configured with a third mounting opening 307 facing away from the first baffle 311, so that the moving wheel 316 can face outwards, suitable for its wheel surface to mate with the contact element. The moving wheel 316 is rotatably disposed in the third mounting opening 307, and the two ends of the rotating shaft of the moving wheel 316 are respectively embedded in the top plate 343 and the bottom plate 344 of the mounting bracket 34 through bearings 306. That is to say, when the moving wheel 316 can be mounted on the mounting bracket 34 and the moving wheel 316 is connected to the mounting bracket 34, the rotating shaft of the moving wheel 316 is embedded in the top plate 343 and the bottom plate 344 of the mounting bracket 34 through the bearings 306, so that the moving wheel 316 can rotate on the mounting bracket 34, and the bearings 306 help to reduce friction and rotate smoothly. In practical applications, the moving wheel 316 can cooperate with the fixed wheel 321 to drive the movement of the contact member. That is, the driving structure 33 drives the fixed wheel 321 to rotate, driving the slender object 9 in contact with the fixed wheel 321. The moving wheel 316 can rotate with the movement of the slender object 9, improving the stability and reliability of the movement.

[0058] Combination Figure 3Optionally, the bottom baffle 314 has a notch 310c at the edge of the first mounting opening 310a, which provides clearance for the installation of the mounting bracket 34 and is suitable for fitting the shape of the mounting bracket 34 for easy installation. Figure 2 and Figure 5 Both the bosses 341 of the bottom plate 344 and the top plate 343 are provided with shaft holes 3410. The shaft hole 3410 of the top plate 343 can be a blind hole. In this way, the rotating shaft of the moving wheel 316 can be matched with the shaft hole 3410, which facilitates the stable rotation of the moving wheel 316.

[0059] Combination Figure 2 and Figure 3 Optionally, the accommodating space is provided with sliding grooves 315 on both the front and rear sides. The sliding grooves 315 extend laterally, and their two ends are respectively blocked by a first baffle 311 and a second baffle 312. The mounting frame 34 is provided with sliders 342 at both the front and rear ends, and the sliders 342 are slidably embedded in the sliding grooves 315 laterally. When the mounting frame 34 moves between the first baffle 311 and the second baffle 312, the sliders 342 can slide in the sliding grooves 315 to restrict and guide the movement of the mounting frame 34, thereby improving the stability of movement and structural stability. The accommodating space is provided with third baffles 313 on both the front and rear sides. The third baffles 313, the first baffles 311, the second baffles 312, and the bottom baffle 314 together surround the accommodating space, which can improve structural stability.

[0060] Optionally, there are multiple accommodating spaces, mounting brackets 34, and moving wheels 316, arranged in a one-to-one correspondence. The combination of multiple accommodating spaces, mounting brackets 34, and moving wheels 316 enables stable positioning of the moving wheels 316 on the contact object, and improves stability during movement. For example, the multiple moving wheels 316 in this invention can be independently and movably mounted on the first mounting base 31. This allows the multiple moving wheels 316 to move relatively independently, thereby achieving more stable support for the contact object and avoiding over-positioning problems caused by the fixed relative positions of the multiple moving wheels 316.

[0061] Specifically, such as Figure 4 As shown, the first mounting base 31 is provided with multiple accommodating spaces. The third baffle 313, the first baffle 311, the second baffle 312 and the bottom baffle 314 together surround these multiple accommodating spaces. The multiple accommodating spaces are arranged in the front-back direction. Adjacent accommodating spaces are separated by a shared third baffle. Each accommodating space is provided with a mounting frame 34, a moving wheel 316, a bearing 306 and a first elastic element 35. The assembly relationship of the mounting frame 34, the moving wheel 316, the bearing 306, the first elastic element 35 and the first mounting base 31 is referred to the corresponding part mentioned above, and will not be repeated here.

[0062] Combination Figures 1 to 10According to an embodiment of the present invention, the pushing component 3 includes: a fixed wheel component 3b and the aforementioned movable wheel component 3a. The fixed wheel component 3b includes a second mounting base 32 and a fixed wheel 321, the fixed wheel 321 being rotatably disposed on the second mounting base 32. The movable wheel component 3a is laterally opposite to the fixed wheel 321, and the movable wheel component 3a is laterally movable. The first mounting base 31 moves to move the movable wheel 316 closer to and further away from the fixed wheel 321 to clamp and release the elongated object 9. The fixed wheel 321 and the movable wheel 316 roll in cooperation to push the clamped elongated object 9 forward or backward.

[0063] In other words, when the first mounting base 31 moves toward the fixed wheel 321, the moving wheel 316 also moves toward the fixed wheel 321. The lateral distance between the moving wheel 316 and the fixed wheel 321 is reduced, which is suitable for clamping the slender object 9 between the moving wheel 316 and the fixed wheel 321. When the fixed wheel 321 and the moving wheel 316 rotate, they can drive the slender object 9 to move forward or backward in the front-back direction, thereby realizing the pushing of the slender object 9.

[0064] According to the present invention, the push assembly 3 can be provided with a movable wheel assembly 3a that can move laterally. The movable wheel 316 can be pushed to move closer to or further away from the fixed wheel 321, so that the fixed wheel 321 and the movable wheel 316 clamp or release the slender object 9. This facilitates the removal of the slender object 9 when it is released and the clamping of the slender object 9. It can also push the slender object 9, improve the convenience of use and the stability of operation of the push assembly 3, and has a simple structure that is easy to construct.

[0065] Combination Figure 4 and Figure 6 Optionally, the second mounting base 32 includes a support plate 322, and the first mounting base 31 is movably supported on the support plate 322 in a laterally lateral manner, which can improve the connection stability. The support plate 322 is provided with a guide groove 301 extending laterally to construct the trajectory of the first mounting base 31 moving laterally. The first mounting base 31 is provided with a guide block 317, which is slidably embedded in the guide groove 301 in a laterally lateral manner, which can limit the longitudinal shaking of the first mounting base 31 when sliding, and improve the operational stability of the guide structure. One end of the guide groove 301 is open to allow the guide block 317 to slide into the guide groove 301 and to facilitate disassembly.

[0066] Optionally, the first mounting base 31 is provided with a plurality of guide blocks 317 arranged at intervals along the front-rear direction, and the support plate 322 is provided with a plurality of guide grooves 301 corresponding one-to-one with the guide blocks 317, so as to improve the stability and balance of the movement of the first mounting base 31. That is, the guide grooves 301 guide the first mounting base 31 to move laterally. The guide grooves 301 can be used to limit the movement of the first mounting base 31 on a fixed guide line, improve the stability of the movement, and thus realize the stable movement of the fixed wheel 321. In addition, when the first mounting base 31 moves laterally on the support plate 322, the contact area between the first mounting base 31 and the support plate 322 changes. By setting a guide structure, the stability of the cooperation between the second mounting base 32 and the first mounting base 31 can be improved.

[0067] Combination Figure 4 Optionally, the guide block 317 includes a connecting portion 317b and a limiting portion 317a. The first mounting base 31 and the limiting portion 317a are respectively disposed on opposite sides of the support plate 322. That is, the first mounting base 31 is disposed on the upper side of the support plate 322, and the support plate 322 can support the first mounting base 31. The limiting portion 317a is disposed on the lower side of the support plate 322 and is suitable for cooperating with the guide groove 301. The connecting portion 317b is connected to the first mounting base 31 and the limiting portion 317a respectively to play a connecting role. The dimension of the limiting portion 317a in the front-back direction is larger than the dimension of the guide groove 301 in the front-back direction. Therefore, the front and rear ends of the limiting portion 317a can abut against the guide groove 301 in the vertical direction, which helps to improve stability.

[0068] Combination Figure 4 and Figure 6 Optionally, a limiting groove 302 is provided on the side of the guide groove 301 opposite to the first mounting base 31. The dimension of the limiting groove 302 in the front-back direction is larger than that of the guide groove 301 in the front-back direction, and the limiting part 317a is slidably embedded in the limiting groove 302 in the lateral direction. The limiting groove 302 is adapted to cooperate with the limiting part 317a, so that the limiting part 317a and the guide groove 301 can be stably cooperated. In the longitudinal direction, the depth of the limiting groove 302 can be the same as the height of the limiting part 317a. After the two are cooperated, their surfaces are flush, which is beneficial for spatial arrangement.

[0069] Combination Figure 9Optionally, a second elastic member 36 is provided between the second mounting base 32 and the first mounting base 31. The second elastic member 36 provides lateral support between the second mounting base 32 and the first mounting base 31, thereby providing elastic support and tension between the second mounting base 32 and the first mounting base 31. Furthermore, multiple second elastic members 36 can be arranged to improve the support effect. Multiple second elastic members 36 can be spaced apart in the front-rear direction, which can improve the overall balance of the pusher assembly. For example, second elastic members 36 can be provided between both the front and rear ends of the second mounting base 32 and the first mounting base 31. Specifically, when the first mounting base 31 moves away from the fixed wheel 321, the second elastic member 36 can provide a thrust to release the elongated object 9.

[0070] Optionally, the second elastic element 36 is a spring. Springs are readily available and can reduce costs. The second elastic element 36 extends laterally, and the two ends of the spring are respectively embedded in the second mounting base 32 and the first mounting base 31, so that the spring force can act on the second mounting base 32 and the first mounting base 31, and the spring embedded in the mounting base can improve the connection stability.

[0071] Combination Figure 6 and Figure 7 Optionally, the second mounting base 32 also includes multiple partitions 323, which can improve the structural strength of the second mounting base 32. The multiple partitions 323 are arranged at intervals on the support plate 322 in the front-back direction. A mounting groove 303 is formed between each two adjacent partitions 323. The mounting groove 303 is laterally opposite to the moving wheel 316. The fixed wheel 321 is rotatably disposed in the mounting groove 303, which avoids mutual interference between the multiple fixed wheels 321 during operation, can improve structural stability, and can also protect the fixed wheel 321.

[0072] According to an embodiment of the present invention, the pushing component 3 has a plurality of fixed wheels 321 arranged at intervals along the front-rear direction on the second mounting base 32, and a plurality of movable wheels 316 provided on the first mounting base 31, with each movable wheel 316 corresponding to one of the fixed wheels 321. Specifically, the contact points between the elongated object 9 and the fixed wheels 321 are laterally opposite, which helps to improve the stability of clamping. When the multiple movable wheels 316 and the multiple fixed wheels 321 cooperate to clamp the elongated object 9, the multiple contact points simultaneously press the elongated object 9, which can ensure the reliability of clamping. When it is necessary to drive the elongated object 9 forward or backward, the driving structure 33 drives the multiple fixed wheels 321 to rotate. The rotation of the multiple fixed wheels 321 and the multiple movable wheels 316 can drive the elongated object 9 to move, and the contact between the elongated object 9 and the multiple movable wheels 316 and the multiple fixed wheels 321 can improve the stability of movement.

[0073] Combination Figure 6 and Figure 7Optionally, the partition 323 is provided with a groove 325, which extends through the partition 323 along its front and rear sides and the side facing away from the support plate 322 in the front-rear direction. The grooves 325 on multiple partitions 323 are opposite each other in the front-rear direction to form a guide groove 305 for guiding the elongated object 9, which is suitable for accommodating the elongated object 9. Specifically, the guide groove 305 is directly constructed on multiple partitions 323. Firstly, this simplifies the structure. Secondly, the partitions 323 are spaced apart, which can improve the support force of the guide groove on the elongated object 9 and improve the balance.

[0074] Combination Figure 6 and Figure 7 Optionally, the push assembly 3 also includes a pressure cap 326. The mounting groove 303 is open on the side away from the support plate 322. The pressure cap 326 covers the mounting groove 303 and is connected to the partition plate 323 via screws to the side of the partition plate 323 where a groove 325 is provided. This connection ensures the guiding depth of the groove 325 and improves structural stability. The pressure cap 326 has a bearing 306 hole, and one side of the fixed wheel 321's bearing 306 is installed in the bearing 306 hole. Specifically, in conjunction with... Figure 7 The pressure cap 326 is connected to the side of the partition plate 323 away from the support plate 322. The two ends of the rotating shaft of the fixed wheel 321 can be rotatably positioned on the support plate 322 and the pressure cap 326 respectively, thereby improving rotational stability.

[0075] Optionally, bearings 306 are provided at both ends of the rotating shaft of the fixed wheel 321 and between the support plate 322 to reduce friction. The bearings 306 are installed in the bearing holes to facilitate the smooth rotation of the fixed wheel 321, improve the structural strength, and thus reduce energy consumption.

[0076] Optionally, the second mounting base 32 and the first mounting base 31 can be configured as an integrally formed structure to facilitate manufacturing and assembly and improve structural strength.

[0077] Combination Figure 8 and Figure 10 Specifically, the first mounting base 31 is supported on the second mounting base 32, which can improve the stability of the connection between the second mounting base 32 and the first mounting base 31. The first mounting base 31 can move laterally to make the moving wheel 316 move laterally closer to and further away from the fixed wheel 321, which can clamp and release the slender object 9. The lateral, longitudinal, and front-back directions are perpendicular to each other.

[0078] Combination Figure 7 Optionally, the second mounting base 32 also includes a back plate 324, which is connected to the support plate 322 and multiple partitions 323 respectively to improve the support effect. The back plate 324 closes the side of the mounting groove 303 away from the moving wheel 316.

[0079] Optionally, the support plate 322 is provided with a first stepped surface 322a and a second stepped surface 322b. The first stepped surface 322a is higher than the second stepped surface 322b. The first stepped surface 322a is used to support the fixed wheel 321, and the second stepped surface 322b is used to support the first mounting base 31. As described above, the fixed wheel 321 and the moving wheel 316 are opposite each other in the lateral direction. Therefore, the higher second stepped surface 322b is suitable for the fixed wheel 321 and the moving wheel 316 to cooperate, so that the fixed wheel 321 and the moving wheel 316 are approximately the same height in the longitudinal direction.

[0080] Combination Figure 6 and Figure 7 Optionally, the rotating shaft of the fixed wheel 321 passes through the support plate 322 and is used to connect the drive structure 33 to drive the fixed wheel 321 to rotate. The drive structure 33 and the rotating shaft are connected below the support plate 322, which is conducive to spatial arrangement.

[0081] Combination Figure 8 and Figure 10 According to an embodiment of the present invention, the pushing component 3 may further include: an inner box body 4 and an inner box cover 5. The inner box body 4 is configured to allow an elongated object 9 to pass through in a front-to-back direction. A fixed wheel assembly 3b and a movable wheel assembly 3a are disposed within the inner box body 4. The inner box cover 5 is rotatably connected to the inner box body 4 to open and close the inner box body 4, thereby facilitating the stable operation of the pushing component 3 within the inner box body 4. When the inner box cover 5 is closed, it presses against the movable wheel assembly 3a, causing the movable wheel assembly 3a to cooperate with the fixed wheel assembly 3b to form a receiving space that can clamp the elongated object 9, and providing damping for the opening of the inner box cover 5. When the inner box cover 5 is open, a receiving space for releasing the elongated object 9 is formed between the movable wheel assembly 3a and the fixed wheel assembly 3b.

[0082] Specifically, the pushing component 3 is installed inside the inner box 4, and the second mounting base 32 is fixedly connected to the inner box 4. The first mounting base 31 is supported on the support plate 322 of the second mounting base 32. The moving wheel 316 of the first mounting base 31 faces the fixed wheel 321 of the second mounting base 32, and the mounting bracket 34 is located on the side away from the second mounting base 32, adjacent to the side wall of the inner box 4. The first mounting base 31 and the inner box 4 are floatingly connected by the second elastic member 36 and the first elastic member 35. The inner box 4 has opening slots 308 at both its front and rear ends, which are opposite to the receiving space between the moving wheel assembly 3a and the fixed wheel assembly 3b, allowing the elongated object 9 to be placed in the opening slots 308 and the receiving space. The inner cover 5 is rotatably connected to the inner box body 4 to open and close the inner box body 4, enclosing the moving wheel assembly 3a and the fixed wheel assembly 3b inside the box, preventing the parts that come into contact with the slender object 9 from being contaminated, and protecting the moving wheel assembly 3a and the fixed wheel assembly 3b to ensure smooth operation during operation.

[0083] More specifically, a push block 51 is provided at the hinge of the inner cover 5. The push block 51 can push the first mounting seat 31 during the opening and closing of the inner cover 5. For example, when the inner cover 5 is closed, the push block 51 presses against the first mounting seat 31 and moves laterally toward the fixed wheel 321. The second elastic element 36 and the first elastic element 35 are compressed, and the moving wheel 316 and the fixed wheel 321 can clamp the elongated object 9 (see...). Figure 10 The fixed wheel 321 and the moving wheel 316 rotate to push the slender object 9. Multiple moving wheels 316 and fixed wheels 321 are provided to improve the reliability of clamping and pushing the slender object 9. When the inner box cover 5 is opened, the push block 51 moves away from the first mounting base 31. The elastic force of the second elastic member 36 between the second mounting base 32 and the first mounting base 31 is released, pushing the first mounting base 31 away from the second mounting base 32 to release the slender object 9, making it easier to pick up the slender object 9.

[0084] Combination Figure 11 According to an embodiment of the present invention, the drive box 100 includes: an outer box body 1, an outer box cover 2, and the aforementioned pushing component 3. The outer box cover 2 is connected to the outer box body 1 to open and close the outer box body 1. The pushing mechanism is rotatably disposed inside the outer box body 1 to rotate the elongated object 9 to push the elongated object 9 forward or backward. Specifically, the upper side of the outer box body 1 is open, and the outer box cover 2 can be opened to seal the open side of the outer box body 1. Guide grooves are provided at both the front and rear ends of the outer box body 1, penetrating the upper surface of the outer box to facilitate the placement of the elongated object 9. The structure of the outer box allows for easy opening to place, remove, or replace the elongated object 9, simplifying the structure of the drive box 100 and facilitating operation.

[0085] Optionally, combined Figure 11 The outer box 1 is provided with a first attractive element 11, and the outer box cover 2 is provided with a second attractive element 21. When the outer box cover 2 is closed, the first attractive element 11 and the second attractive element 21 are attracted by magnetic force. Among them, one of the first attractive element 11 and the second attractive element 21 is a magnet, and the other is made of iron-containing material, or both are magnets.

[0086] Reference Figure 11The second suction body 21 can be disposed on the outer cover 2 at one end away from its rotation axis. There can be one of these two bodies, distributed at the two corners of the outer cover 2. A receiving groove for the second suction body 21 is provided on the outer cover 2, and the second suction body 21 is disposed within the receiving groove of the first suction body 11. The first suction body 11 and the second suction body 21 are disposed in a one-to-one correspondence on the outer box 1. A receiving groove for the first suction body 11 is provided on the outer box 1, and the first suction body 11 is disposed within the receiving groove of the second suction body 21. When the outer cover 2 is closed, the first suction body 11 and the second suction body 21 are attracted together, further preventing the outer cover 2 from automatically opening during the operation of the drive box 100. Of course, corresponding suction bodies can also be provided on the inner box 4 and the outer box to improve the stability of the switch; the invention is not limited to this.
