Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to a clamping system. BACKGROUND

[0002] In recent years, the incidence of valve regurgitation is increasing. The methods for treating valve regurgitation disease mainly include surgical thoracotomy and minimally invasive interventional surgery. Surgical thoracotomy has great trauma to patients, and minimally invasive interventional surgery has less trauma, and patients recover faster, so the application of minimally invasive interventional surgery is increasingly widespread.

[0003] At present, the research and development for minimally invasive interventional surgery is mostly concentrated on the delivery system for valve repair, and less attention is paid to the clamping device for fixing the delivery system. The optimization of the clamping device also has an effect that cannot be ignored on the improvement of the effect of minimally invasive interventional surgery. This is because the delivery system generally includes multiple layers of catheters and multiple control handles. When the delivery system sends the implant into the heart valve position through the vein, the control handle needs to control the catheter in multiple planes and multiple angles to enable the implant to be accurately positioned. In this process, the clamping device needs to be used to clamp the delivery system to maintain the position and angle of the delivery system when necessary.

[0004] The clamping device used in the prior art and the delivery system generally use a screw tightening fixation scheme, which causes the need to loosen the screw every time the angle of the delivery system needs to be adjusted, and then the adjustment is performed. After the adjustment is completed, the screw is tightened again. The operation is complex, time-consuming, and easy to miss the implant capture time. Moreover, in the process of retightening the screw, the angle of the delivery system may be offset, which makes it difficult for the implant to accurately reach the lesion site. In addition, due to the structural limitation of the delivery system, the current clamping device cannot clamp the delivery system at any position of the system, thereby causing the delivery system to be unable to be fixed at any position. SUMMARY

When the angle of the delivery system is adjusted, the operator can directly apply a force to the delivery system to overcome part of the elastic potential energy of the first elastic member to make the delivery system rotate, which is simple and convenient, time-saving, and when the angle adjustment is completed, the operator stops applying force to the delivery system, the delivery system immediately stops rotating, and the clamping mechanism re-clamps the delivery system, without the parts of the clamping mechanism moving to cause the delivery system to deviate in angle.

The guide mechanism is fixed in a specified position, once the clamping mechanism and the guide mechanism are locked, the position of the clamping mechanism is fixed. In this way, the clamping mechanism can be first clamped on the position that can be clamped by the conveying system, and then the clamping mechanism is controlled to move in the first direction to adjust the axial position of the conveying system when the locking member releases the locking between the clamping mechanism and the guide mechanism, so as to realize the effect of fixing the conveying system in any suitable position in the axial direction.

It should be noted that the drawings are very simplified and use non-precise proportions, and are only used to facilitate and clarify the purpose of assisting the description of the embodiments of the present application. The same or similar reference numerals in the drawings represent the same or similar parts.

[0066] The clamping system includes a clamping mechanism 100 (such as Figures 1 to 3 annotated). Figure 1Fig. 1 shows a schematic view of a clamping mechanism 100 of a clamping system according to an embodiment of the present application, Figure 2 Fig. 2 shows a cross-sectional view of the clamping mechanism 100, Figure 3 and Figure 4 Fig. 3 shows a schematic view of the clamping mechanism 100 in different states. Referring to Figures 1 to 4 , the clamping mechanism 100 comprises a first clamping block 1000, a second clamping block 2000 and a first elastic member 3000. The first clamping block 1000 has an inner cavity (not labeled in the figures). The first clamping block 1000 further has a first through slot 1010 extending through the first clamping block 1000 in a first direction, the first through slot 1010 partially overlaps with the inner cavity. The second clamping block 2000 is at least partially disposed in the inner cavity and is capable of moving relative to the first clamping block 1000 in a second direction, the second direction being perpendicular to the first direction. The second clamping block 2000 further has a second through slot 2010 extending through the second clamping block 2000 in the first direction, the second through slot 2010 is capable of at least partially overlapping with the first through slot 1010. The first elastic member 3000 is disposed between the first clamping block 1000 and the second clamping block 2000. The clamping mechanism 100 is configured such that when the second clamping block 2000 is moved in a positive direction of the second direction relative to the first clamping block 1000 under an external force, the overlapping area of the second through slot 2010 and the first through slot 1010 increases, and the first elastic member 3000 stores elastic potential energy. When the external force is removed, the first elastic member 3000 releases the elastic potential energy and drives the second clamping block 2000 to move in a negative direction of the second direction relative to the first clamping block 1000, and the overlapping area of the second through slot 2010 and the first through slot 1010 decreases.

[0067] The clamping system is used for clamping a delivery system 10 in the medical field, the delivery system 10 is used for delivering an implant to a predetermined position in a patient's body, in some embodiments, the implant is a prosthetic heart valve, and the predetermined position is a valve where regurgitation exists, for example, the mitral valve, the tricuspid valve or the aortic valve. In practice, the clamping mechanism 100 can have a first state as shown in Figure 3 , a second state as shown in Figure 4 and a third state as shown in Figure 5The first state can be the initial state of the clamping mechanism 100, in which the second through slot 2010 partially overlaps with the first through slot 1010. Then, by applying an external force to the second clamping block 2000, the second clamping block 2000 moves in the positive direction of the second direction relative to the first clamping block 1010 to the second state, and the first elastic member 3000 stores elastic potential energy. When the clamping mechanism 100 is in the second state, the second through slot 2010 completely overlaps with the first through slot 1010. At this time, the delivery system 10 can be inserted into the through slots. Then, the external force is removed, and the first elastic member 3000 begins to release the elastic potential energy and drives the second clamping block 2000 to move in the negative direction of the second direction until the delivery system 10 simultaneously abuts against the slot walls of the second through slot 2010 and the first through slot 1010. It can be understood that when the delivery system 10 simultaneously abuts against the slot walls of the second through slot 2010 and the first through slot 1010, the delivery system 10 hinders the movement of the second clamping block 2000 in the negative direction of the second direction, thereby hindering the first elastic member 3000 from continuously releasing the elastic potential energy. This makes the second clamping block 2000 unable to return to the initial position, and the first elastic member 3000 still stores elastic potential energy, so the first elastic member 3000 can provide a clamping force and abut against the second clamping block 2000, thereby enabling the second clamping block 2000 and the first clamping block 1000 to clamp the delivery system 10. Since the first elastic member 3000 is a flexible component, when the clamping mechanism 100 clamps the delivery system, if it is necessary to rotate the delivery system 10 for angle adjustment, the operator can directly apply a force to the delivery system 10 and rotate it. That is, the clamping mechanism 100 of the clamping system can allow the delivery system 10 to directly rotate under the action of an external force for angle adjustment while clamping the delivery system 10, without the need to loosen the clamping of the delivery system 10 by the clamping mechanism 100, and thus there is no need to clamp the delivery system 10 again after angle adjustment, which has the advantage of simple and convenient operation. Furthermore, once the external force controlling the rotation of the delivery system 10 is removed, the delivery system 10 immediately stops rotating, and since the operator does not perform other operations on the clamping mechanism 100, the delivery system 10 does not rotate under other operations and thus the adjusted angle is not offset. In other words, the application of the clamping system is conducive to the accurate delivery of the implant by the delivery system 10 to the predetermined position, thereby improving the treatment effect.

[0068] It is worth mentioning that the "external force" refers to the force from a person or object other than the components of the clamping system, which is generally the force from the operator. The specific directions of the first direction and the second direction are determined according to the actual situation. For example, in the orientation shown in the figure, the first direction is the front-back direction, i.e. the X direction shown in the figure, and the second direction is the up-down direction, i.e. the Z direction shown in the figure. Optionally, the first elastic member 3000 is a spring, and the upper end of the spring is connected with the second clamping block 2000, and the lower end of the spring is connected with the first clamping block 1000. Therefore, the positive direction of the second direction is the downward direction, and the negative direction of the second direction is the upward direction. Figure 1

[0069] Optionally, the lower end of the second clamping block 2000 is provided with a first accommodating cavity. The upper end of the first elastic member 3000 is arranged in the first accommodating cavity, and the lower end of the first elastic member is arranged in the inner cavity. The number of the first elastic members 3000 can be multiple. When the clamping mechanism 100 is in the first state, the bottom of the second clamping block 2000 is arranged in the inner cavity, and when the clamping mechanism 100 is in the second state, the bottom of the second clamping block 2000 abuts against the bottom of the inner cavity.

[0070] Preferably, please continue to refer to Figures 1 to 5 , the first through groove 1010 includes a first clamping portion 1011 and a first opening portion 1012 which are in communication with each other, and the first opening portion 1012 and the first clamping portion 1011 are arranged along a third direction. The first opening portion 1012 is arranged at one side of the first clamping portion 1011. Correspondingly, the second through groove 2010 includes a second clamping portion 2011 and a second opening portion 2012 which are in communication with each other, and the second opening portion 2012 and the second clamping portion 2011 are arranged along the third direction, and the second opening portion 2012 is located at one side of the second clamping portion 2011. The third direction is perpendicular to the first direction and the second direction, and in the orientation shown in the figure, the third direction is the left-right direction, i.e. the Y direction shown in the figure. Figure 1 ​In the indicated orientation, the third direction is the left-right direction, i.e., the Y direction in the figure. The second clamping part 2011 is used to at least partially overlap with the first clamping part 1011, and the second opening part 2012 is used to at least partially overlap with the first opening part 1012. Preferably, when the clamping mechanism 100 is in the second state, the second clamping part 2011 completely overlaps with the first clamping part 1011, and the second opening part 2012 completely overlaps with the first opening part 1012. Thus, when the conveying system 10 is inserted onto the clamping mechanism 100, the conveying system 10 can smoothly enter the two clamping parts that are in the overlapping state from the two openings in the overlapping state. When the clamping mechanism 100 clamps the conveying system 10, the conveying system 10 actually abuts against the lower groove bottom of the second clamping part 2011 and the upper groove bottom of the first clamping part 1011.

[0071] Optionally, the end of the inner cavity away from the first elastic member 3000 is formed as a third opening (not shown in the figure), and a portion of the structure of the second clamping block 2000 can enter and exit the inner cavity through the third opening. The clamping mechanism 100 also includes a pressing block 4000, which is placed on the end of the second clamping block 2000 away from the first elastic member 3000 and located outside the first clamping block 1000. The operator applies a force to the pressing block 4000 to drive the second clamping block 2000 to move in the positive direction of the second direction. The pressing block 4000 has a large surface area, which provides the operator with a good feel during operation.

[0072] Furthermore, the clamping mechanism 100 of the clamping system provided in this embodiment of the invention can be disposed in a guide mechanism 200 (such as...). Figure 6 and Figure 7 (as indicated in the image), and the clamping mechanism 100 further includes a locking element 5000 (such as...). Figure 8As shown in FIG. 5, the locking member 5000 is used to selectively lock or unlock the clamping mechanism 100 and the guiding mechanism 200. When the locking member 5000 unlocks the clamping mechanism 100 and the guiding mechanism 200 (i.e. the locking member 5000 does not lock the clamping mechanism 100 and the guiding mechanism 200), the clamping mechanism 100 is allowed to move along the first direction on the guiding mechanism 200, while when the locking member 5000 locks the clamping mechanism 100 and the guiding mechanism 200, the clamping mechanism 100 is prevented from moving along the first direction on the guiding mechanism 200, i.e. the clamping mechanism 100 is fixed on the guiding mechanism 200. In practice, the guiding mechanism 200 is fixed at a designated position, in other words, when the clamping mechanism 100 is fixed on the guiding mechanism 200, the position of the clamping mechanism 100 in space is fixed. Therefore, after the clamping mechanism 100 clamps the conveying system 10 at a position where clamping is allowed, the position of the conveying system 10 in space can be adjusted by moving the clamping mechanism 100 on the guiding mechanism 200, achieving the effect that the conveying system 10 is fixed at any position.

[0073] Preferably, the clamping system further comprises the guiding mechanism 200. In an alternative embodiment, as shown in FIG. 2, the guiding mechanism 200 comprises a guiding seat 210 and two limiting flaps 220. Figure 6 and Figure 7 As shown in FIG. 2, the guiding mechanism 200 comprises a guiding seat 210 and two limiting flaps 220. The guiding seat 210 is provided with a guiding groove 211 extending along the first direction. The two limiting flaps 220 both extend along the first direction. The two limiting flaps 220 are arranged in the third direction and each limiting flap 220 is connected with a groove wall of the guiding groove 211.

[0074] It should be noted that the "the guiding groove 211 extends along the first direction" refers to the extending direction of the guiding groove 211 is the first direction when the clamping mechanism 100 is arranged on the guiding mechanism 200. Similarly, the "the two limiting flaps 220 are arranged in the third direction" refers to the arrangement direction of the two limiting flaps 220 is the third direction when the clamping mechanism 100 is arranged on the guiding mechanism 200.

[0075] As shown in FIG. 2, the guiding mechanism 200 is matched with the clamping mechanism 100. Figure 2 , Figure 8 , Figures 10 to 13As shown, the clamping mechanism 100 further comprises a connecting portion 6000, which comprises a base 6100, a first limiting protrusion 6200 and a second limiting protrusion 6300. The base 6100 is connected to the first clamping block 1000, specifically to the end of the first clamping block 1000 away from the third opening. The first limiting protrusion 6200 and the second limiting protrusion 6300 are respectively located on the opposite sides of the base 6100 in the third direction. The first limiting protrusion 6200 and the second limiting protrusion 6300 are configured to be arranged in the guide slot 211 of the guide mechanism 200 and cooperate with the two limiting flaps 220 to limit the clamping mechanism 100 on the guide mechanism 200.

[0076] Specifically, the maximum dimension L1 of the guide slot 211 in the third direction is greater than or equal to the maximum width of the connecting portion 6000, and the distance L2 between the two limiting flaps 220 is less than the maximum width of the connecting portion 6000. The width of the connecting portion 6000 is equal to the maximum distance between the first limiting protrusion 6200 and the second limiting protrusion 6300, which refers to the distance L3 between the surface of the first limiting protrusion 6200 away from the base 6100 and the surface of the second limiting protrusion 6300 away from the base 6100, i.e., the width of the connecting portion 6000 is equal to the maximum distance between the first limiting protrusion 6200 and the second limiting protrusion 6300, which refers to the distance L3 between the mutually facing surfaces of the first limiting protrusion 6200 and the second limiting protrusion 6300. Therefore, after the first limiting protrusion 6200 and the second limiting protrusion 6300 are inserted into the guide slot 211, the two limiting flaps 220 will prevent the two limiting protrusions from being separated from the guide slot 211, thereby preventing the clamping mechanism 100 from being separated from the guide mechanism 200. The method of inserting the two limiting protrusions into the guide slot 211 will be described in detail below.

[0077] Please continue to refer to Figure 8 , Figures 10 to 17The locking member 5000 comprises a pressing block 5100, a first driving part 5200 and a second elastic member 5300. The pressing block 5100 is movably arranged on the base 6100, and has a locking position and an unlocking position. The first driving part 5200 is arranged on the base 6100, and is configured to drive the pressing block 5100 to move in the positive direction of the second direction to the locking position. The second elastic member 5300 is arranged between the pressing block 5100 and the base 6000, and is configured to store elastic potential energy when the pressing block 5100 moves in the positive direction of the second direction, and is further configured to drive the pressing block 5100 to move in the negative direction of the second direction to the unlocking position when the elastic potential energy is released. The second elastic member 5300 is, for example, a spring.

[0078] When the pressing block 5100 is in the locking position, the pressing block 5100 protrudes from the bottom of the base 6000, and can lock the clamping mechanism 100 and the guide mechanism 200. When the pressing block 5100 is in the unlocking position, at the end away from the first clamping block 1000, preferably the pressing block 5100 does not protrude from the bottom of the base 6000, for example, the two are flush.

[0079] Please refer to Figure 13 When the locking member 5000 locks the clamping mechanism 100 and the guide mechanism 200, the pressing block 5100 abuts against the bottom of the guide groove 211, and the first limiting block 6200 abuts against one of the limiting flaps 220, and the second limiting block 6300 abuts against another limiting flap 220. When the locking member 5000 releases the locking between the clamping mechanism 100 and the guide mechanism 200, the connecting part 6000 and the guide groove 211 are clearance-fitted.

[0080] Here, the limiting flap 220 used for abutting against the first limiting block 6200 is referred to as the first limiting flap 220a (as shown in Figure 7 and Figure 13 annotated), and the limiting flap 220 used for abutting against the second limiting block 6300 is referred to as the second limiting flap 220b (as shown in Figure 7 and Figure 13To achieve the above object, when the first limiting protrusion 6200 is flush with the base 6100 at one end away from the first clamping block 1000, and the second limiting protrusion 6300 is flush with the base 6100 at one end away from the first clamping block 1000, the distance h1 of the first limiting baffle 220a to the guide groove 221 should be greater than the size d1 of the first limiting protrusion 6200 in the second direction, the distance h2 of the second limiting baffle 220b to the guide groove 221 should be greater than the size d2 of the second limiting protrusion 6300 in the second direction, and when the pressing block 5100 is in the locked position, the size d3 of the part of the pressing block 5100 protruding from the base 6100 in the second direction is equal to the difference between the distance h1 of the first limiting baffle 220a to the guide groove 221 and the size d1 of the first limiting protrusion 6200 in the second direction.

[0081] The various components of the locking member 5000 and the base 6100 can have any suitable configuration as long as they can achieve the above functions.

[0082] In a non-limiting embodiment, as shown in Figure 8 、 Figures 10 to 17 The first driving part 5200 is located on the side of the pressing block 5100 close to the first clamping block 1000, and the first driving part 5200 is movably connected with the base 6100. The first driving part 5200 is configured to move under the action of an external force and drive the pressing block 5100 to move in the positive direction of the second direction, or allow the second elastic member 5300 to release elastic potential energy.

[0083] Optionally, as shown in Figures 8 to 10 The axis of the first driving part 5200 extends in the third direction, and the first driving part 5200 is configured to be able to rotate around its axis. A driving groove 5201 is provided on the side wall of the first driving part 5200, and the groove wall of the driving groove 5201 is in contact with one end of the pressing block 5100 close to the first clamping block 1000. The locking member 5000 is configured such that when the pressing block 5100 is in the unlocked position, the first driving part 5200 can rotate under the action of an external force and drive the pressing block 5100 to move in the positive direction of the second direction, and when the pressing block 5100 is in the locked position, the first driving part 5200 rotates under the action of an external force and makes the second elastic member 5300 release elastic potential energy.

[0084] Specifically, the driving groove 5201 extends one round along the circumference of the first driving part 5200, and the cross section (i.e. the section perpendicular to the axial direction of the first driving part 5200) of the first driving part 5200 at the driving groove 5201 is a rectangle, and the long side and the short side of the rectangle are both the edge line of the driving groove 5201 parallel to the groove wall of the first driving part 5200. In the case that the pressing block 5100 is in the unlocking position, the long side of the rectangle is in a horizontal state. In this case, when the first driving part 5200 rotates under the action of an external force, for example, rotates along the fourth direction, the first driving part 5200 applies a force F to the pressing block 5100 through the groove wall where the long side is located, and the force F has a component f1 along the positive direction of the second direction. Therefore, the first driving part 5200 can drive the pressing block 5100 to move along the positive direction of the second direction until the pressing block 5100 reaches the locking position. In this process, the long side of the rectangle gradually switches to a vertical state, and the short side of the rectangle gradually switches to a horizontal state, that is, when the pressing block 5100 reaches the locking position, the short side of the rectangle is in a horizontal state. At the same time, in this process, the pressing block 5100 applies a force to the second elastic member 5300 and makes the second elastic member 5300 store elastic potential energy. In the case that the pressing block 5100 is in the locking position, when the first driving part 5200 rotates under the action of an external force, for example, rotates along the fifth direction, the first driving part 5200 stops applying a force F to the pressing block 5100, and makes the second elastic member 5300 release the elastic potential energy. The fifth direction is opposite to the fourth direction, that is, one of the fourth direction and the fifth direction is clockwise, and the other is counterclockwise. Of course, since the cross section of the first driving part 5200 at the driving groove 5201 is a rectangle, in the case that the pressing block 5100 is in the locking position, if the first driving part 5200 rotates along the fourth direction under the action of an external force, the second elastic member 5300 can also release the elastic potential energy.

[0085] In another embodiment, as Figure 11 and Figure 12As shown, the pressing block 5100 is provided with a transmission slope 5101 at one end close to the first clamping block 1000, and the distance from the transmission slope 5101 to the first clamping block 1000 gradually decreases along the positive direction of the third direction. Correspondingly, the first driving part 5200 is provided with a driving slope 5202, the distance from the driving slope 5202 to the first clamping block 1000 gradually decreases along the positive direction of the third direction, and the driving slope 5202 partially abuts against the transmission slope 5101. The first driving part 5200 is configured to be able to reciprocate linearly along the third direction relative to the base 6100 under the action of an external force. Thus, when the first driving part 5200 moves along the positive direction of the third direction under the action of an external force in the case where the pressing block 5100 is in the unlocking position, the first driving part 5200 applies a force to the transmission slope 5101 through the driving slope 5202, and drives the pressing block 5100 to move along the positive direction of the second direction. When the first driving part 5200 moves along the negative direction of the third direction under the action of an external force in the case where the pressing block 5100 is in the locking position, the first driving part 5200 no longer applies a force to the transmission slope 5101 of the pressing block 5100, so as to allow the second elastic member 5300 to release elastic potential energy. In this embodiment, the first driving part 5200 is provided with a first driving slope 5201 and a second driving slope 5202, and the first driving slope 5201 and the second driving slope 5202 are arranged in the same direction. Figure 11 and Figure 12 As an example, the positive direction of the third direction is a horizontal right direction, and the negative direction of the third direction is a horizontal left direction. The driving slope 5202 and the transmission slope 5101 are both rough surfaces, and there is a frictional force between the two, so that the first driving part 5200 can only move along the third direction under the action of an external force, thereby controlling the movement of the pressing block 5100 along the second direction.

[0086] Optionally, the base 6100 is provided with a second accommodating cavity (not labeled in the figure) and a third accommodating cavity (not labeled in the figure), the second accommodating cavity extends along the third direction, and the third accommodating cavity extends along the second direction. The first driving part 5200 is partially accommodated in the second accommodating cavity, and the pressing block 5100 is at least partially arranged in the third accommodating cavity.

[0087] In addition, in this embodiment, the third elastic member 5300 can be a spring. As Figures 8 to 12As shown, the pressing block 5100 can include a pressing block body 5110 and a stopper 5120 arranged at one end of the pressing block body 5110 away from the first clamping block 1000, the stopper 5120 extending along the circumference of the pressing block body 5110. The third elastic member 5300 can be in a plurality, and the plurality of third elastic members 5300 can be arranged at intervals along the circumference of the pressing block body 5110, and the lower end of each third elastic member 5300 can be connected with the stopper 5120, and the upper end can be connected with the cavity wall of the third accommodating cavity. When the pressing block 5100 moves in the positive direction of the second direction, the pressing block 5100 can apply a pulling force to the third elastic member 5300, so that the third elastic member 5300 is stretched and deformed and stores elastic potential energy. In some alternative embodiments, as shown in FIG. 6B, the stopper 5120 can be arranged at one end of the body 5110 close to the first clamping block, so that the lower end of the third elastic member 5300 is connected with the cavity wall of the third accommodating cavity, and the upper end is connected with the stopper 5120. In another alternative embodiment, the pressing block can only include the body, and does not include the stopper, so that the number of the third elastic member can be one, and the third elastic member can be sleeved on the body. When the lower end of the third elastic member close to the first clamping block is connected with the body, and the upper end of the third elastic member away from the first clamping block is connected with the cavity wall of the third accommodating cavity (not shown in the figure), if the pressing block moves in the positive direction of the second direction, the pressing block can apply a pressure to the third elastic member, so that the third elastic member is compressed and deformed, and stores elastic potential energy. When the upper end of the third elastic member away from the first clamping block is connected with the body, and the lower end of the third elastic member close to the first clamping block is connected with the cavity wall of the third accommodating cavity (not shown in the figure), if the pressing block moves in the positive direction of the second direction, the pressing block can apply a pulling force to the third elastic member, so that the third elastic member is stretched and deformed, and stores elastic potential energy. Figure 13 As shown, the stopper 5120 can be arranged at one end of the body 5110 close to the first clamping block, so that the lower end of the third elastic member 5300 is connected with the cavity wall of the third accommodating cavity, and the upper end is connected with the stopper 5120. In another alternative embodiment, the pressing block can only include the body, and does not include the stopper, so that the number of the third elastic member can be one, and the third elastic member can be sleeved on the body. When the lower end of the third elastic member close to the first clamping block is connected with the body, and the upper end of the third elastic member away from the first clamping block is connected with the cavity wall of the third accommodating cavity (not shown in the figure), if the pressing block moves in the positive direction of the second direction, the pressing block can apply a pressure to the third elastic member, so that the third elastic member is compressed and deformed, and stores elastic potential energy. When the upper end of the third elastic member away from the first clamping block is connected with the body, and the lower end of the third elastic member close to the first clamping block is connected with the cavity wall of the third accommodating cavity (not shown in the figure), if the pressing block moves in the positive direction of the second direction, the pressing block can apply a pulling force to the third elastic member, so that the third elastic member is stretched and deformed, and stores elastic potential energy.

[0088] Next, an optional implementation of placing the first limiting block 6200 and the second limiting block 6300 into the guide groove 211 is introduced.

[0089] Please refer to Figure 8 , Figures 10 to 17The first limiting block 6200 is connected with the base 6100 and keeps relative static with the base 6100, and the second limiting block 6300 can move relative to the base 6100. The clamping mechanism 1000 further comprises an adjusting member 7000, which is connected with the second limiting block 6200 and is configured to drive the second limiting block 6300 to move relative to the base 6100, so as to change the maximum distance between the second limiting block 6300 and the first limiting block 6100, and thus change the width of the connecting part 6000. In other words, the width of the connecting part 6000 is variable, and as mentioned above, the distance L2 between the two limiting flaps 220 of the guide mechanism 200 is smaller than the maximum width of the connecting part 6000. When the width of the connecting part 6000 is reduced to be smaller than the distance L2 between the two limiting flaps 220 by driving the second limiting block 6300 to move by the adjusting member 7000, the first limiting block 6200 and the second limiting block 6300 can be placed into the guide slot 211, and then the width of the connecting part 6000 can be increased to tightly clamp the guide slot 211 by driving the second limiting block 6200 to move by the adjusting member 7000.

[0090] Optionally, as shown in Figure 1 and Figures 10 to 17 , the clamping mechanism 1000 further comprises a housing 8000, which wraps part of the structure of the connecting part 6000. The adjusting member 7000 comprises a second driving part 7100 and a third elastic member 7200, and the second driving part 7100 is movably connected with the housing 8000. When the second driving part 7100 moves under the driving of external force, the second driving part 7100 drives the end of the second limiting block 6300 away from the first limiting block 6200 to move in the direction close to the base 6100, so as to reduce the distance between the surface of the second limiting block 6300 away from the base 6100 and the surface of the first limiting block 6200 away from the base 6100, and make the third elastic member 7200 store elastic potential energy. When the third elastic member 7200 releases the elastic potential energy, the third elastic member 7200 drives the end of the second limiting block 6300 away from the first limiting block 6200 to move in the direction away from the base 6100, so as to increase the distance between the surface of the second limiting block 6300 away from the base 6100 and the surface of the first limiting block 6200 away from the base 6100, and also drive the second driving part 7100 to move reversely and reset.

[0091] Optionally, as shown in Figure 15 and Figure 16As shown, the second limiting block 6300 is movably connected with the base 6100 through the third elastic member 7200. The second driving portion 7100 includes a force receiving rod 7110 and a transmission rod 7120 connected at an angle, the second driving portion 7100 is rotatably connected with the shell 8000 at the joint of the force receiving rod 7110 and the transmission rod 7120 through a central shaft 7130, and the transmission rod 7120 is further connected with the second limiting block 6300. Alternatively, the central shaft 7130 is rotatably connected with the shell 8000, and the second driving portion 7100 remains relatively static with the central shaft 7130. In this way, when the second driving portion 7100 rotates in a sixth direction around the central shaft 7130 under the action of an external force, the second driving portion 7100 drives the second limiting block 6300 to rotate in the sixth direction around the central shaft 7130, so that one end of the second limiting block 6300 away from the first limiting block 6200 gradually approaches the base 6100, and the third elastic member 7200 is compressed to store elastic potential energy. When the external force is removed, the third elastic member 7000 releases the elastic potential energy and drives the second limiting block 6300 and the second driving portion 7100 to rotate in a seventh direction around the central shaft 7130. The seventh direction is opposite to the sixth direction, and in practice, one of the sixth direction and the seventh direction is clockwise and the other is counterclockwise. For example, as shown in the orientation, the sixth direction is clockwise and the seventh direction is counterclockwise. Figure 15 and Figure 16 For example, as shown in the orientation, the sixth direction is clockwise and the seventh direction is counterclockwise.

[0092] In an alternative embodiment, please refer to Figure 8 , Figures 10 to 12The second limiting block 6300 is movably connected with the base 6100 through the third elastic member 7200, and the second limiting block 6300 is connected with the second driving part 7100. The second driving part 7100 is slidingly connected with the shell 8000, and the second driving part 7100 is configured to be capable of moving in the third direction along the direction of approaching or moving away from the base 6100 relative to the shell 8000. Therefore, when the second driving part 7100 is driven by an external force to move in the third direction along the direction of approaching the base 6100, the second driving part 7100 drives the second limiting block 6300 to move in the third direction along the direction of approaching the base 6100, and compresses the third elastic member 7200 to make the third elastic member 7200 store elastic potential energy. When the external force is removed, the third elastic member 7200 releases the elastic potential energy, pushes the second limiting block 6300 to move in the third direction along the direction of moving away from the base 6100, and drives the second driving part 7100 to move in the third direction along the direction of moving away from the base 6100.

[0093] In another alternative embodiment, as Figure 17As shown, the second limiting block 6300 is rotatably connected with the shell 8000. The third elastic member 7200 connects the second driving part 7100 and the second limiting block 6300. Specifically, the second limiting block 6300 comprises an angularly connected block body 6310 and an engaging block 6320, the engaging block 6320 is angularly arranged with the block body 6310, and the third elastic member 7200 connects the second limiting block 6300 and the engaging block 6320, the engaging block 6320 is rotatably connected with the shell 8000. The second driving part 7100 is also rotatably connected with the shell 8000. In an alternative implementation, the shell 8000 is provided with a fixed shaft 9000, the fixed shaft 9000 remains relatively static with the shell 8000. The second driving part 7100 is rotatably sleeved on the fixed shaft 9000, and the engaging block 6320 is also rotatably sleeved on the fixed shaft 9000 (i.e., the second driving part 7100 and the engaging block 6320 are rotatably connected with the shell 8000 through the fixed shaft 9000). In this embodiment, when the second driving part 7100 rotates around the fixed shaft 9000 in the sixth direction under the action of an external force, the second driving part 7100 drives the second limiting block 6300 to rotate around the fixed shaft 9000 in the sixth direction so that one end of the second limiting block 6300 away from the first limiting block 6200 approaches the base 6100, and the third elastic member 7200 is compressed to store elastic potential energy. When the external force is removed, the third elastic member 7200 releases the elastic potential energy and drives the second limiting block 6300 and the second driving part 7100 to rotate around the fixed shaft 9000 in the seventh direction until the second limiting block 6300 and the second driving part 7100 are reset.

[0094] While the application has been disclosed with reference to the above embodiments, it will be understood by those skilled in the art that various changes can be made and equivalents can be substituted for elements thereof without departing from the scope of the application. In addition, many modifications can be made to adapt to a particular situation and the application is intended to cover such modifications. Therefore, it is aimed that the application not be limited to the embodiments discussed above, but be accorded with a fair scope of the claims and their equivalents.
