Detailed implementation mode

[0019] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application. Embodiment

[0020] As Figures 1 to 10 shown, an intervention guide wire shaping device in this embodiment includes a shaping mechanism, a conveying mechanism, a baking mechanism, a discharging chute, and a discharging pushing member. The shaping mechanism is used to install the intervention guide wire; the conveying mechanism conveys the shaping mechanism to the vertical moving mechanism; the vertical moving mechanism is installed on the horizontal moving mechanism, and the horizontal moving mechanism is installed close to the conveying mechanism; the baking mechanism is installed close to the horizontal moving mechanism; the horizontal mechanism drives the vertical moving mechanism and the shaping mechanism to move, and the shaping mechanism drives one end of the intervention guide wire to be inserted into the baking mechanism for baking; the extending direction of the discharging chute is parallel to the conveying direction of the conveying mechanism, and a vertical height difference is formed with the conveying mechanism; the vertical moving mechanism pushes the shaping mechanism to the feeding end of the discharging chute; the discharging pushing member is installed above the conveying mechanism and is horizontally spaced and aligned with the discharging chute, and is used to push the shaping mechanism on the vertical moving mechanism into the feeding end.

[0021] The intervention guide wire shaping device of the present invention is for the intervention guide wire made of nitinol. Due to its shape memory effect and superelasticity, nitinol needs to be stabilized in a specific shape through a baking and setting process during the manufacture of the intervention guide wire.

[0022] It should be noted that for medical nickel-titanium guide wires, the Af temperature (austenite termination temperature) needs to be set to ≤ 37 °C (human body temperature) in order to spontaneously recover the original shape at normal body temperature.

[0023] For the convenience of operation, a controller 5 is additionally installed. The controller is electrically connected to the conveying mechanism, the horizontal moving mechanism, the vertical moving mechanism, the discharging pushing member, and the baking mechanism. The conveying mechanism, the horizontal moving mechanism, the vertical moving mechanism, the discharging pushing member, and the baking mechanism can work together through the controller.

[0024] The present invention may further include a working box 1. The top surface of the working box 1 can be used to install the shaping mechanism, the conveying mechanism, the baking mechanism, the discharging chute, the controller 5, and the discharging pushing member.

[0025] An installation structure of the controller 5: The controller 5 is installed on the working box 1 through a support column 4.

[0026] The baking mechanism is used to bake the shaped end of the intervention guide wire on the shaping mechanism to heat and shape the shaped end of the intervention guide wire. One structure of the baking mechanism: The baking mechanism includes a baking oven 9 and an electric heating tube 7. One end of the electric heating tube 7 is in a ring structure for baking the intervention guide wire on the shaping mechanism, and the other end is electrically connected to the baking oven 9.

[0027] The electric heating tube 7 adopts a ring structure, which can evenly heat the intervention guide wire inserted therein, so that the intervention guide wire inside the ring is evenly heated.

[0028] In order to prevent the electric heating tube from spreading heat to the surrounding, a protective box 8 is additionally installed. The electric heating tube 7 is installed in the protective box 8. An entrance and exit 81 is opened on the protective box 8, and the entrance and exit 81 allows the shaping mechanism to extend into the protective box 8 and the ring structure of the electric heating tube.

[0029] In order to prevent the shaping mechanism from colliding with the electric heating tube when extending into the protective box, a guide rod 6 is additionally installed. As Figures 1 to 4 shown, the guide rod 6 is installed in the protective box 8 and is located between the electric heating tube 7 and the entrance and exit 81. A limiting port 61 is opened at the top of the guide rod 6, and a guiding port 62 with an outward-expanded opening is opened on one side of the limiting port 61 close to the entrance and exit 81.

[0030] The geometric center of the limiting port can be aligned with the center of the ring structure of the electric heating tube. The shaping mechanism is inserted into the entrance and exit 81 and moved to the guiding port 62. The guiding port 62 guides the shaping mechanism to insert into the limiting port 61, and then inserts into the ring structure of the electric heating tube through the limiting port 61. It can effectively prevent the shaping mechanism inserted into the protective box from colliding with the electric heating tube, and thus can protect the electric heating tube.

[0031] Working mode: One end at the top of the shaping mechanism clamps and fixes the shaped end of the intervention guide wire, and the other end clamps at the 1 / 3 length of the intervention guide wire, so that the intervention guide wire between the two ends at the top of the shaping mechanism is tightened.

[0032] The shaping mechanism with the intervention guide wire installed is placed into the conveying mechanism. The conveying mechanism transports the shaping mechanism to the vertical moving mechanism. The vertical moving mechanism drives the shaping mechanism and the intervention guide wire to rise to the feeding port of the discharging slideway. The horizontal moving mechanism drives the vertical moving mechanism, the shaping mechanism and the intervention guide wire to move towards the baking mechanism. When one end of the shaping mechanism drives the intervention guide wire to insert into the baking mechanism, the baking mechanism bakes the shaped end of the intervention guide wire. The baking temperature can be selected from 400 to 500 °C, and the baking duration is 5 to 10 seconds.

[0033] After baking, the horizontal moving mechanism reversely pushes the vertical moving mechanism, the shaping mechanism and the intervention guide wire towards the unloading slideway, slides until one end of the shaping mechanism aligns with the inlet of the unloading slideway, the unloading pusher pushes the shaping mechanism into the inlet of the unloading slideway, and the unloading slideway guides the incoming shaping mechanism. The vertical moving mechanism descends to the discharge end of the conveying mechanism to receive the next shaping mechanism. The above operations are repeated in a cycle.

[0034] In some alternative embodiments, a structure of the shaping mechanism is given. As Figure 5 , 7 , as shown in 8, the shaping mechanism includes a sliding seat 136, a support plate 131, a clamping seat 132 and a support column 135. A locking member is installed on the sliding seat; one end of the support plate 131 is connected to the sliding seat 136 and the other end extends outward; the clamping seat 132 is provided with a clamping member 134 and is installed at the other end of the support plate 131; the support column 135 is installed on the support plate 131 near the clamping seat 132.

[0035] The shaping end of the intervention guide wire acts through the clamping seat 132, the clamping member 134 and the support column 135 together. The clamping member 134 vertically penetrates the clamping seat 132 and can rotate relative to the clamping seat 132.

[0036] To facilitate the manipulation of the clamping member 134, an adjusting rod 133 is additionally installed. A through hole is opened at the top of the clamping member 134. When the clamping member needs to be rotated, the adjusting rod 133 is inserted into the through hole, the adjusting rod 133 is driven to rotate, and the adjusting rod 133 drives the clamping member to rotate.

[0037] As Figure 8 shown, a structure of the clamping member 134 is given. The clamping member 134 has a cylindrical structure. A vertical notch is opened on the side of the clamping seat 132 near the support column 135. A clamping opening 1341 is opened along the length direction of the clamping member 134, and a bending surface 1342 is opened on one side of the clamping opening 1341.

[0038] A shape of the clamping opening 1341 can be a V-shaped structure. It is convenient for the intervention guide wire to be inserted, and when the clamping member rotates, the V-shaped structure squeezes the intervention guide wire against the clamping seat 132 to drive the intervention guide wire to move.

[0039] A shaping method for the shaping end of the intervention guide wire: the locking member clamps and fixes the intervention guide wire, then the intervention guide wire is bent through the support column 135 and extends and is inserted into the notch on the clamping seat 132 and the clamping opening 1341 on the clamping member 134 in sequence. The adjusting rod 133 is used to drive the clamping member 134 to rotate, the clamping opening 1341 drives the end of the intervention guide wire to be inserted into the gap between the clamping member 134 and the clamping seat 132. When continuing to rotate, the bending surface 1342 squeezes the intervention guide wire, so that while the intervention guide wire is in a straightened state, the end face of the intervention guide wire is bent and shaped.

[0040] It should be noted that the relative position between the clamping seat 132 and the support column 135 can be adjusted. One adjustment method: The clamping seat 132 is movably connected to the support plate 131. By changing the installation position of the clamping seat 132 on the support plate 131, the positional relationship between the clamping seat 132 and the support column 131 can be changed (for example, changing the inclination angle of the clamping seat 132 relative to the support column, the interval between the clamping seat and the support column, etc.), and thus the shaping structure of the intervention guide wire can be changed.

[0041] One structure of the locking member includes a first fixing plate 137, a movable plate 138, a second fixing plate 139 and a locking rod 1310. The first fixing plate 137 and the second fixing plate 139 are installed in parallel and at intervals on the sliding seat 136. The movable plate 138 is movably placed between the first fixing plate 137 and the second fixing plate 139. The locking rod 1310 passes through the first fixing plate 137 or the second fixing plate 139 and is threadedly connected to the movable plate 138.

[0042] It can be understood that when the locking rod 1310 is rotated, the movable plate 138 can move between the first fixing plate 137 and the second fixing plate 139, and the movable plate 138 can squeeze and fix the intervention guide wire to the first fixing plate 137 or the second fixing plate 139.

[0043] The support plate 131 extends out of the sliding seat 136. In order to enable the sliding seat 136 to move stably on the conveying mechanism, a limiting platform 1362 and a support platform 1361 are sequentially arranged on the sliding seat 136 in a stepped form from bottom to top. The support platform 1361 is used to support and install the locking member, and the limiting platform 1362 is used to rollingly connect with the conveying mechanism.

[0044] As Figure 7 shown, the limiting platform 1362 and the support plate 131 are installed on the corresponding side surfaces of the sliding seat 136. The support plate 131 extends out of the sliding seat 136, and the limiting platform 1362 is rollingly connected to the conveying mechanism, which can prevent the support plate 131 from pulling the sliding seat 136 to tilt up, and can enable the sliding seat to move smoothly on the conveying mechanism.

[0045] It should be noted that the support plate 131 drives the clamping seat 132, the clamping member 134 and the support column 135 to insert into the annular heating tube. The heating tube can bake and heat the shaping end of the intervention guide wire on the clamping seat 132, the clamping member 134 and the support column 135, which is convenient for shaping and setting the shaping end of the intervention guide wire.

[0046] Further, a structure of the conveying mechanism includes a conveyor 2 and a conveyor frame 29, and the conveyor 2 is installed on the conveyor frame 29. The conveyor 2 includes a conveyor belt 21, a first guide plate 3 and a second guide plate 19. The first guide plate 3 and the second guide plate 19 are respectively installed on one side of the conveyor belt 21, and the first guide plate 3 and the second guide plate 19 are parallel to each other.

[0047] The first guide plate 3 and the second guide plate 19 mutually restrict the sliding seat 136, so that the sliding seat 136 moves stably along the conveying direction of the conveyor belt 21.

[0048] A structure of the limiting platform rolling-connected to the conveying mechanism is given. A rolling mechanism is additionally installed. A plurality of rolling mechanisms are installed at intervals and in parallel along the conveying direction of the conveying mechanism, and the rolling mechanisms are rolling-connected to the limiting platform 1362.

[0049] Installing a plurality of rolling mechanisms at intervals and in parallel along the conveying direction of the conveying mechanism can facilitate the limiting platform 1362 on the sliding seat 136 to maintain a rolling connection with the rolling mechanisms.

[0050] Further, a structure of the rolling mechanism is given. As Figure 2 shown, the rolling mechanism includes a rolling element 22, a nut 23 and a screw 24. One end of the rolling element 22 is connected to the screw 24, and the other end of the screw 24 is threadedly connected to the nut 23; the rolling element 22 can rotate relative to the screw 24 and is used for rolling connection with the limiting platform 1362.

[0051] The structure of the rolling element 22 can be a roller or a roller barrel. When installing the roller or the roller barrel, the rotating shaft of the roller or the roller barrel is connected to the screw. The roller or the roller barrel can rotate relative to the screw.

[0052] An installation method of the rolling mechanism: The rolling mechanism is installed on the second guide plate 19. A plurality of rolling mechanisms are installed at intervals along the length direction of the second guide plate 19. When installing, one end of the screw 24 penetrates through the second guide plate 19 and is connected to the rolling element 22, and the other end is threadedly connected to the nut 23.

[0053] In order for the rolling element to rotate more smoothly, a limiting ring is installed on the screw near the rolling element. When the nut 23 is tightened, the nut 23 and the limiting ring clamp the second guide plate 19. The limiting ring can prevent the rolling element from fitting against the second guide plate.

[0054] In this embodiment, further, in order for the rolling element to rollingly contact the limiting platform, one end of the limiting platform 1362 is provided with an inclined surface 13621. The rolling element can smoothly roll onto the limiting platform by means of the inclined surface 13621 and is rolling-connected to the limiting platform.

[0055] It is understandable that when the limiting platform is at different heights of the sliding seat, in order to make the limiting platform and the rolling element rollingly connected, a plurality of adjustment slots 191 are provided on the second guide plate 19. Each adjustment slot 191 is used to install a rolling mechanism. During installation, the screw rod is passed through the adjustment slot 191 and connected to the nut. When the nut is in a loose state, the screw rod can move along the vertical height of the adjustment slot to adjust the height of the rolling element. When the height is adjusted to the desired height, the nut is tightened, so that the rolling element and the limiting platform have good rolling contact.

[0056] A structure of a discharge chute is provided: the discharge chute 12 is provided with a chute 121, a limiting plate 122 is provided on one side of the top of the chute 121, the width of the limiting plate 122 is equal to the width of the limiting platform 1362, and the limiting plate 122 and the bottom surface of the chute 121 form a limiting groove 123. When the sliding seat slides into the chute 121, the limiting platform 1362 is inserted into the limiting groove 123, the top surface of the limiting platform is slidably connected with the bottom surface of the limiting plate 122, and the limiting plate prevents the limiting platform from tilting upward, so that the sliding seat as a whole moves smoothly along the chute.

[0057] In some optional embodiments, a structure of a vertical movement mechanism is provided. Figure 5 , 9 As shown, the vertical moving mechanism 17 includes a base plate 1710 , an L-shaped support 173 , a first limiting plate 171 , a supporting rod 174 , a vertical driving member 178 , a baffle 172 , a first limiting block 179 and a second limiting block 1712 . The first limiting plate 171 is connected to the L-shaped support 173 to form a slide groove; one end of the support rod 174 is connected to the L-shaped support 173, and the other end is connected to the vertical slider 175, and the vertical slider 175 is slidably installed on the vertical guide rail 177, and the vertical guide rail 177 is installed on the base plate 1710; the vertical driving member 178 is transmission-connected to the vertical slider 175 and installed on the base plate 1710; the baffle 172 is installed on the L-shaped support 173, and is movable to prevent the shaping mechanism from falling through the discharge port of the conveying mechanism; the first limit block 179 and the second limit block 1712 are installed in parallel on the base plate 1710 at intervals along the length direction of the vertical guide rail 177; wherein, the vertical slider 175 is provided with a protrusion 1711, and the protrusion 1711 is located and moves between the first limit block 179 and the second limit block 1712.

[0058] The first limiting plate 171 is connected to the L-shaped support 173 to form a slide groove, and the slide groove is used to receive the shaping mechanism unloaded from the conveying mechanism.

[0059] It is understandable that the first limiting plate 171 may be installed with multiple rolling mechanisms at intervals along the length direction, so that when the shaping mechanism enters the slide groove, the sliding seat in the shaping mechanism remains in rolling connection with the rolling mechanism, thereby preventing the sliding seat from tilting in the slide groove.

[0060] The baffle 172 can block the stay unloading end of the shaping mechanism conveyed by the conveying mechanism, and can prevent the shaping mechanism from detaching from the conveying mechanism. During operation, the baffle will move vertically and horizontally. In order to maintain the blocking of the unloading end of the conveying mechanism, the baffle 172 can be divided into a vertical blocking section and a horizontal blocking section 1721, and the vertical blocking section is connected to the horizontal blocking section 1721. When the L-shaped support 173 is located above the conveying mechanism, the vertical blocking section blocks the unloading end of the conveying mechanism. When the horizontal moving mechanism drives the vertical moving mechanism to move horizontally, the horizontal blocking section 1721 moves to block the unloading end of the conveying mechanism, maintaining the blocking of the unloading end of the conveying mechanism, and can prevent the shaping mechanism on the conveying mechanism from falling.

[0061] In some alternative embodiments, a structure of the horizontal moving mechanism is given. As Figure 5 , 6 shown, the horizontal moving mechanism includes a horizontal base plate 254, a horizontal guide rail 255, a horizontal slider 257, a horizontal guide block 252, and a horizontal driving member 251. A first horizontal limit block 253 is installed at one end of the horizontal base plate 254, and a second horizontal limit block 258 is installed at the other end; the horizontal guide rail 255 is installed on the horizontal base plate 254 and extends along the length direction of the horizontal base plate 254; the horizontal slider 257 is slidably installed on the horizontal guide rail 255 and is used to support and install the vertical moving mechanism; the horizontal guide block 252 is installed on the horizontal base plate 254; the horizontal driving member 251 is provided with a horizontal piston 2511 and is installed on the horizontal guide block 252, and the horizontal piston 2511 passes through the horizontal guide block 252 and is in transmission connection with the horizontal slider 257.

[0062] The horizontal slider 257 is used to support and install the vertical moving mechanism 17. Specifically, the base plate 1710 in the vertical moving mechanism is installed on the horizontal slider 257.

[0063] The horizontal driving member 251 drives the horizontal piston 2511 to contract, and the horizontal piston 2511 pulls the horizontal slider 257 to move along the horizontal guide rail 255 towards the first horizontal limit block 253; when moving to touch the first horizontal limit block 253, the horizontal driving member 251 pauses working, and the pause time can be 5 to 10 seconds. Subsequently, the horizontal driving member 251 drives the horizontal piston 2511 to extend, pushing the horizontal slider 257 to move away from the first horizontal limit block 253. When moving to touch the second limit block 258, the horizontal driving member 251 pauses working, and the horizontal piston 2511 pauses working.

[0064] It can be understood that the first horizontal limit block 253 and the second horizontal limit block 258 limit the reciprocating stroke of the horizontal slider 257.

[0065] In some alternative embodiments, to ensure stable movement of the shaping mechanism on the vertical moving mechanism, a supporting mechanism 26 is additionally installed. The supporting mechanism 26 is mounted on the vertical moving mechanism and is used to actively press and hold the shaping mechanism 13 on the vertical moving mechanism.

[0066] A structure of the supporting mechanism 26. The supporting mechanism 26 includes a supporting driving member 261, a supporting guiding block 262, and a supporting base plate 263. The supporting driving member 262 is provided with a supporting piston. The supporting base plate 263 is mounted on the L-shaped support 173 in the vertical moving mechanism 17, and the supporting guiding block 262 is mounted on the supporting base plate 263. The supporting piston passes through the supporting guiding block 262 and actively transfers the L-shaped support 173, and actively supports the sliding seat 136 in the shaping mechanism.

[0067] The working mode of the supporting mechanism: Tightening work: The supporting driving member 262 drives the supporting piston to pass through the supporting guiding block 262, and the L-shaped support 173 supports the sliding seat 136, tightly pressing the sliding seat 136 against the first limiting plate 171 to achieve supporting and fixing the sliding seat 136.

[0068] Loosening work: When the sliding seat needs to be unloaded from the L-shaped support 173 into the unloading chute 12, the supporting piston releases the tightening effect and applies a driving force pointing to the unloading chute 12 to the second fixing plate 139 in the shaping mechanism, and the shaping mechanism is pushed into the unloading chute.

[0069] In some alternative embodiments, an installation structure of the unloading driving member is given. A vertical rod 10, a horizontal rod 11, and an unloading guiding block 20 are additionally installed. The vertical rod 10 is vertically installed, one end of the horizontal rod 11 is mounted on the vertical rod 10, and the other end extends above the conveying mechanism and is connected to the unloading guiding block 20; the unloading driving member includes an unloading driving member 18, the unloading driving member 18 is provided with a piston 181, and is mounted on the unloading guiding block 20. The piston 181 passes through the unloading guiding block 20 and is used to actively push the shaping mechanism on the vertical moving mechanism into the unloading chute 12.

[0070] It should be noted that the horizontal driving member, the vertical driving member, and the supporting driving member can all adopt the structure of a pneumatic cylinder.

[0071] According to the above embodiments of the present invention, the working mode of the present invention: The intervention guide wire to be baked is installed on the shaping mechanism, that is, the intervention guide wire 14 is threaded between the second fixed plate 139 and the movable plate 138, extends to the support column 135 and is bent, and then extends and is inserted into the notch on the clamping seat 132 and the clamping opening 1341 of the clamping member 134 in sequence to adjust the required length. Subsequently, turn the lock rod 1310, and the lock rod 1310 moves the movable plate 138 towards the second fixed plate 139. Tighten the lock rod 1310, and the movable plate 138 will be closely attached to the second fixed plate 139. The movable plate 138 and the second fixed plate 139 clamp and fix the intervention guide wire 14. Then, drive the clamping member 134 to rotate through the adjusting rod 133. While the clamping opening 1341 squeezes the intervention guide wire against the clamping seat 132, it also pulls the intervention guide wire to move, so that the intervention guide wire between the clamping seat 132 and the support column 135 and between the support column 135 and the sliding seat 136 is straightened. Place the sliding seat 136 on the conveyor belt 21 of the conveyor 2. The limiting platform 1362 on the sliding seat 136 is in rolling connection with the rolling mechanism installed on the second guide plate 19, and the conveyor belt 21 conveys the sliding seat to the vertical moving mechanism 17.

[0072] In the initial state, the first limiting plate 171 is connected to the L-shaped support 173 to form a chute that is aligned with the discharge port of the conveyor 2, and the shaping mechanism 13 conveyed on the conveyor belt 21 is unloaded into the chute.

[0073] The vertical driving member 178 is activated to drive the vertical piston 176 to extend upward. The vertical piston 176 pushes the vertical slider 175 to move upward along the vertical guide rail 177. When the convex block 1711 touches the second limiting block 1712, at this time, the support plate 131 can be aligned with the center of the annular electric heating tube; and the vertical blocking section of the baffle 172 blocks the discharge port of the conveyor, which can prevent the shaping mechanism on the conveyor belt from falling off. The horizontal driving member 251 drives the horizontal piston 2511 to contract. The horizontal piston 2511 pulls the horizontal slider 257 towards the first horizontal limiting block 253. When it moves to touch the first horizontal limiting block 253, the horizontal driving member 251 pauses working. The support plate 131 in the shaping mechanism 13 drives the clamping seat 132, the support column 135, the clamping member 134 and the shaping end of the intervention guide wire to insert into the annular electric heating tube 7. The electric heating tube 7 then bakes and heats the intervention guide wire. The baking temperature can be set on the controller 5 to be 400 - 500 °C, and the baking duration is 5 - 10 seconds.

[0074] When baked to the set time, the controller 5 controls the horizontal driving member 251 to operate, driving the horizontal piston 2511 to extend outwards. The horizontal piston 2511 pushes the horizontal slider 257 to move along the horizontal guide rail 255 towards the second horizontal limit block 258. The horizontal slider 257 drives the vertical moving mechanism 17 and the shaping mechanism 13 to move away from the electric heating tube. When moving to touch the second horizontal limit block 251, at this time, the horizontal driving member 251 pauses working, and the first limiting plate 171 and the L-shaped support 173 are connected to form a chute that is aligned with the chute 121 on the unloading chute 12.

[0075] At this time, the controller 5 controls the unloading driving member 18 to start. The unloading driving member 18 drives the piston 181 to instantaneously extend outwards, pushing the second fixed plate 139. The second fixed plate 139 then drives the entire shaping mechanism to slide into the chute 121 of the unloading chute 12. After the piston extends and strikes, it instantaneously retracts.

[0076] The controller 5 then controls the vertical driving member 178 to start. The vertical driving member 178 drives the vertical piston 176 to contract, and the vertical slider 175 and the supporting rod 14 move downwards. The L-shaped support 173 drives the baffle 172 to move downwards. During the process of the baffle moving downwards, the vertical blocking section of the baffle remains blocking the unloading end of the conveyor, which can always prevent the shaping mechanism on the conveyor belt from falling. When moving down to the convex block 1711 touching the first limit block 179, at this time, the chute formed by the connection of the first limiting plate 171 and the L-shaped support 173 is aligned with the unloading end of the conveyor 2. The conveyor belt 21 pushes a shaping mechanism to fall into the chute. The controller then controls the vertical driving member 178 to start. The vertical driving member 178 drives the vertical piston 176 to extend upwards, driving the L-shaped support 173 and the shaping mechanism to move upwards. When moving to touch the second limit block 1712, at this time, the chute formed by the connection of the first limiting plate 171 and the L-shaped support 173 is aligned with the chute of the unloading chute; and this operation is repeated in a cycle.

[0077] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
