[0001] The present invention relates to the technical field of medical devices, and particularly to a forceps lifting mechanism, an end of an endoscope, and an endoscope. Background Art

[0002] In clinical practice, endoscopes are commonly used to examine patients, in order to obtain high-definition images of pathological sites or extract tissues from pathological sites for clinical diagnosis through techniques such as optical imaging and ultrasonic detection. An endoscope mainly consists of a connection part, an operation part, and an insertion part. The connection part is mainly used to connect with an external light source device, an ultrasonic treatment unit, etc. The operation part is mainly used to control the export of treatment instruments and the bending of the insertion part, etc. The insertion part is used to insert into the human body for examination.

[0003] The upright platform of the insertion part is an important component of the endoscope. It can guide treatment instruments such as ultrasonic aspiration needles and biopsy forceps that enter the human body through the endoscope channel, facilitating the development of endoscopic diagnosis and treatment operations. The insertion part of the endoscope is a medical device that directly contacts the internal cavity of the human body. Therefore, it needs to be strictly disinfected after use. However, due to the complex structure of the upright platform of the insertion part and the narrow space nearby, it is difficult to thoroughly clean it during the disinfection of the insertion part. Summary of the Invention

[0015] In one embodiment, the installation groove includes a mating groove and a receiving groove communicating with each other. The rotating member is inserted into the receiving groove and at least partially abuts against the groove wall of the receiving groove. At least a part of the clamping block is received in the mating groove. The side of the elastic member facing away from the clamping block is connected to the groove wall of the mating groove. The clamping block is slidably connected to the groove wall of the mating groove to guide the movement of the clamping block away from the rotating member.

[0016] In one embodiment, the forceps lifting mechanism further includes a steel wire rope. One end of the steel wire rope extends into the storage groove and is connected to the rotating member. The steel wire rope is configured to drive the rotating member to rotate when being pushed or pulled.

[0017] In one embodiment, the transmission assembly further includes a first connecting rod and a second connecting rod. The first connecting rod is connected to the rotating member.

[0042] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , Figure 1 is a schematic diagram of the pliers lifting mechanism provided by an embodiment of the present invention; Figure 2 is a schematic diagram of the end of the endoscope provided by an embodiment of the present invention; Figure 3 is a schematic diagram of the endoscope provided by an embodiment of the present invention; Figure 4 is Figure 2 the cross-sectional view at A-A in Figure 5 is Figure 2Cross-sectional view taken along line B-B in the present invention. An embodiment of the present invention provides a clamping mechanism, which includes a lifting platform 200 and a transmission assembly 100; the lifting platform 200 is used to be inserted into a receiving groove 410 formed on the head end seat 440 of the insertion portion 400, and an installation groove 210 is formed at the end located in the receiving groove 410; the transmission assembly 100 includes a rotating member 110 rotatably arranged in the receiving groove 410 around an axis, and the rotating member 110 is inserted into the installation groove 210 from the notch of the installation groove 210; an elastic clamping member 300 is arranged on the groove side wall of the installation groove 210, and the elastic clamping member 300 has an unlocked state and a locked state. In the locked state, the elastic clamping member 300 is configured to be able to elastically abut against the rotating member 110 to limit the relative separation of the rotating member 110 and the installation groove 210, and enable the lifting platform 200 to rotate synchronously under the drive of the rotating member 110; in the unlocked state, the elastic clamping member 300 releases the rotating member 110, so that the rotating member 110 and the installation groove 210 can relatively move to disengage.

[0043] The clamping mechanism in the present application is applied to an endoscope, and the endoscope includes a connecting portion 600, an operating portion 500, and an insertion portion 400 connected in sequence. The connecting portion 600 is used to connect with an external light source device, an ultrasonic treatment unit, etc., the operating portion 500 is used to control the export of the treatment instrument, the bending of the insertion portion 400, etc., and the insertion portion 400 is used to be inserted into the human body for examination. Among them, the end of the insertion portion 400 is provided with a head end seat 440, the head end seat 440 is provided with a clamping channel hole 430 and a receiving groove 410 that communicate with each other, and the clamping mechanism is arranged in the receiving groove 410 to guide the treatment instrument passing through the clamping channel hole 430.

[0044] Specifically, in the present application, in the locked state, the elastic clamping member 300 elastically abuts against the rotating member 110, thereby restricting the relative separation of the rotating member 110 and the installation groove 210, so that the lifting platform 200 can rotate synchronously with the rotating member 110. In the unlocked state, the elastic clamping member 300 releases the rotating member 110, so that the rotating member 110 and the installation groove 210 can relatively move to disengage, thereby facilitating the separation of the lifting platform 200 and the rotating member 110 and disengaging from the receiving groove 410, further facilitating the cleaning of the lifting platform 200, reducing the cleaning difficulty, and reducing the time consumed by the disinfection operation.

[0045] It should be noted that the rotating member 110 in the present application is always disposed in the receiving groove 410. The erecting platform 200 is inserted into the receiving groove 410 and cooperates with the rotating member 110 through the installation groove 210, so that the rotating member 110 can drive the erecting platform 200 to rotate in the receiving groove 410, thereby realizing the guiding of the treatment instrument passing through the forceps channel hole 430. Among them, when the rotating member 110 is relatively separated from the installation groove 210, in fact, the erecting platform 200 moves relative to the rotating member 110, so that the rotating member 110 disengages from the installation groove 210 of the erecting platform 200.

[0046] It should be noted that the groove wall of the installation groove 210 is divided into a groove side wall and a groove bottom wall. The groove bottom wall is located on the side opposite to the notch of the installation groove 210. If the elastic clamping member 300 is disposed on the groove bottom wall of the installation groove 210, the elastic clamping member 300 will apply a force towards the notch of the installation groove 210 to the rotating member 110. Therefore, it is defined that the elastic clamping member 300 is disposed on the groove side wall of the installation groove 210, so that in the locked state, the elastic clamping member 300 can apply a stable restraining force to the rotating member 110 to limit the relative movement between the rotating member 110 and the installation groove 210 to disengage.

[0047] Refer to Figure 6 and Figure 7 , Figure 6 is a cross-sectional view of the rotating member inserted into the installation groove in the forceps lifting mechanism provided by an embodiment of the present invention; Figure 7 is Figure 6 The enlarged view of C in. In one embodiment, the elastic clamping member 300 includes a clamping block 310 and an elastic member 320. One end of the elastic member 320 is connected to the clamping block 310, and the other end is connected to the groove wall of the installation groove 210. The elastic member 320 is used to apply a thrust force towards the rotating member 110 to the clamping block 310, so that the clamping block 310 abuts against the rotating member 110 in the locked state.

[0048] Specifically, in the locked state, the elastic member 320 exerts a thrust force on the latch 310 towards the rotating member 110, such that one end of the latch 310 away from the elastic member 320 can abut tightly against the rotating member 110, thereby increasing the frictional force between the latch 310 and the rotating member 110 to restrict the movement of the rotating member 110 relative to the latch 310. The elastic clamping member 300 is disposed on the groove side wall of the mounting groove 210, thereby restricting the movement of the rotating member 110 relative to the groove side wall of the mounting groove 210, enabling the rotating member 110 to be stably mounted in the mounting groove 210. When the rotating member 110 rotates about an axis, the upright platform 200 can rotate synchronously to guide the treatment instrument passing through the clamping channel hole 430. In the unlocked state, the elastic member 320 can provide a space for the latch 310 to move away from the rotating member 110, such that the latch 310 can move away from the rotating member 110, thereby releasing the rotating member 110, enabling the rotating member 110 and the groove side wall of the mounting groove 210 to move relative to each other to disengage, thereby facilitating the upright platform 200 to disengage from the receiving groove 410, facilitating the cleaning of the upright platform 200 and the insertion portion 400, and further reducing the cleaning difficulty and the time consumed by the disinfection operation. Preferably, the elastic member 320 is a spring.

[0049] In this application, by providing the elastic member 320, the latch 310 can exert a stable abutting force on the rotating member 110. At the same time, a space can be provided for the latch 310 to move away from the rotating member 110, enabling the latch 310 to easily release the rotating member 110 and facilitating the relative disengagement of the rotating member 110 from the groove wall of the mounting groove 210 of the upright platform 200, thereby improving the adaptability of the mechanism.

[0050] Furthermore, in the direction perpendicular to the rotation axis 113 line of the rotating member 110, elastic clamping members 300 are provided on both groove side walls of the mounting groove 210, thereby being able to provide stable abutting forces on both sides of the rotating member 110 to stably restrict the relative disengagement of the rotating member 110 from the mounting groove 210, improving the stability of the connection between the upright platform 200 and the rotating member 110 in the locked state.

[0051] Wherein, for the sake of convenience of description, the rotation axis 113 line of the rotating member 110 is defined as the first direction, the elastic clamping member 300 is disposed on the groove wall of the mounting groove 210 along the second direction, the first direction is perpendicular to the second direction, and the direction perpendicular to both the first direction and the second direction is defined as the third direction. It should be noted that, taking the Figure 1 specification appendix

[0052] for example, XX' is defined as the first direction, YY' is defined as the second direction, and ZZ' is defined as the third direction. The following descriptions will all be made in terms of the first direction, the second direction, and the third direction. Figure 6 、 Figure 7 、 Figure 8 andFigure 9 , Figure 8 A cross-sectional view of the rotating member disengaging from the mounting groove in the lifting clamp mechanism provided by an embodiment of the present invention; Figure 9 is Figure 8 An enlarged view of portion D in. In one embodiment, a clamping groove 111 is provided on the rotating member 110, and a limiting portion 312 adapted to the clamping groove 111 is formed on the clamping block 310. In the locked state, the limiting portion 312 is engaged with the clamping groove 111 to restrict the relative movement of the rotating member 110 and the groove wall of the mounting groove 210.

[0053] Specifically, the limiting portion 312 is located on the side of the clamping block 310 facing the rotating member 110. In the locked state, under the thrust of the elastic member 320, the limiting portion 312 extends into the clamping groove 111 and is engaged with the clamping groove 111, thereby applying a stable limiting force to the rotating member 110, restricting the relative separation of the rotating member 110 and the mounting groove 210, and improving the connection stability between the upright platform 200 and the rotating member 110.

[0054] Furthermore, a first abutting surface 316 is formed on the side of the limiting portion 312 facing away from the notch of the mounting groove 210. The first abutting surface 316 is perpendicular to the insertion direction of the rotating member 110 and the mounting groove 210, so as to provide a stable limiting force to the rotating member 110 in the locked state, and further improve the connection stability between the upright platform 200 and the rotating member 110.

[0055] Even further, a second abutting surface 315 is formed on the side of the limiting portion 312 facing the rotating member 110. In the direction from the notch to the bottom of the mounting groove 210, the second abutting surface 315 is inclined from the side of the elastic member 320 towards the side of the rotating member 110. Thus, when the rotating member 110 and the mounting groove 210 of the upright platform 200 are relatively inserted, interference with the rotating member 110 can be reduced. At the same time, during the relative movement of the rotating member 110 and the groove wall of the mounting groove 210, the limiting portion 312 can be slowly squeezed, reducing resistance and facilitating the relative insertion of the rotating member 110 and the mounting groove 210.

[0056] Referring to Figure 6 , Figure 7 , Figure 8 and Figure 9 , in one embodiment, a sliding hole 240 for an external auxiliary tool 700 to pass through is provided on the upright platform 200. The sliding hole 240 communicates with the mounting groove 210, so that the end of the auxiliary tool 700 extends into the sliding hole 240 and extends to the clamping block 310 to push the clamping block 310 to move away from the rotating member 110, so that the elastic clamping member 300 is changed from the locked state to the unlocked state.

[0057] Specifically, one side of the sliding hole 240 away from the mounting groove 210 has an inlet communicating with the outside. When the upright platform 200 needs to be disassembled, an auxiliary tool 700 is inserted into the sliding hole 240 from the inlet, and the auxiliary tool 700 is continuously pushed, so that the end of the auxiliary tool 700 can extend into the mounting groove 210 and abut against the clamping block 310, thereby applying a thrust force to the clamping block 310. Since one side of the clamping block 310 away from the pushing member is connected to the elastic member 320, the elastic member 320 can contract, providing space for the clamping block 310 to move toward the side away from the rotating member 110, enabling the clamping block 310 to move away from the rotating member 110, thereby releasing the rotating member 110, and allowing the rotating member 110 and the mounting groove 210 to move relative to each other to disengage.

[0058] Refer to Figure 6 , Figure 7 , Figure 8 and Figure 9 , in one embodiment, the pliers lifting mechanism further includes a pushing block 330. The pushing block 330 is disposed on a side of the clamping block 310 away from the notch of the mounting groove 210. A wedge-shaped portion 314 is formed on the clamping block 310 to cooperate with the inclined surface of the pushing block 330. The pushing block 330 is configured to move along the extending direction of the sliding hole 240 under the push of the auxiliary tool 700 to push the wedge-shaped portion 314 to move away from the rotating member 110.

[0059] Specifically, a wedge-shaped portion 314 is formed on a side of the clamping block 310 facing the pushing block 330. A second inclined surface 311 is formed on the wedge-shaped portion 314. A first inclined surface 331 is formed on a side of the pushing block 330 facing the clamping block 310. The first inclined surface 331 is in contact and cooperation with the second inclined surface 311. When disassembling the upright platform 200, the auxiliary tool 700 applies a thrust force along the extending direction of the sliding hole 240 to the pushing block 330. Through the contact and cooperation between the first inclined surface 331 and the second inclined surface 311, the pushing block 330 can apply a component force to the wedge-shaped portion 314 to move away from the rotating member 110, thereby enabling the clamping block 310 to move away from the rotating member 110.

[0060] Among them, the setting of the inclined surface cooperation between the pushing block 330 and the wedge-shaped portion 314 makes the setting position and extending direction of the sliding hole 240 not restricted, improving the adaptability of the mechanism. And compared with the setting where the pushing block 330 and the auxiliary tool 700 are integrated, the particularity of the auxiliary tool 700 is reduced. That is, only a general tool that can extend into the sliding hole 240 can be used to push the pushing block 330 to move, improving the convenience of disassembling the upright platform 200.

[0061] Furthermore, the sliding hole 240 extends along the plugging direction of the standing platform 200 and the receiving groove 410, thereby facilitating the insertion of the auxiliary tool 700 into the sliding hole 240 from the end of the standing platform 200 away from the rotating member 110, reducing interference with the groove wall of the receiving groove 410 and improving operational convenience.

[0062] See also Figure 4 and Figure 8 In one embodiment, the direction in which the rotating member 110 is plugged into the mounting groove 210 is parallel to the direction in which the standing platform 200 is plugged into the receiving groove 410 .

[0063] Specifically, when disassembling the stand 200 in the unlocked state, it is only necessary to pull the stand 200 out of the storage slot 410, so that the rotating member 110 and the notch of the installation slot 210 can be relatively disengaged, thereby improving the convenience of disassembling the stand 200. Preferably, the direction in which the rotating member 110 and the installation slot 210 are relatively plugged in is parallel to the third direction.

[0064] See also Figure 7 and Figure 9 In one embodiment, the pushing block 330 includes a wedge-shaped end 332 and a connecting end 333 connected to each other, the wedge-shaped end 332 is used to cooperate with the inclined surface of the wedge-shaped portion 314, and the projected edge of the wedge-shaped end 332 in the extension direction of the sliding hole 240 is located outside the sliding hole 240, and the connecting end 333 is at least partially penetrated into the sliding block and is slidably connected to the hole wall of the sliding hole 240.

[0065] Specifically, the size of the wedge-shaped end 332 in the extension direction of the sliding hole 240 is larger than that of the connecting end 333 and the sliding hole 240, so that the push block 330 can be restricted from sliding out of the sliding hole 240, thereby improving the stability of the mechanism. The connecting end 333 is at least partially inserted into the sliding block and is slidably connected to the hole wall of the sliding hole 240, thereby guiding the movement of the push block 330 under the push of the auxiliary tool 700, so that the push block 330 stably moves along the extension direction of the sliding hole 240, thereby stably pushing the wedge-shaped portion 314, so that the clamping block 310 stably moves to the side away from the rotating member 110, thereby improving the stability of the mechanism.

[0066] See also Figure 7 and Figure 9 In one embodiment, the raising platform 200 is further provided with an auxiliary groove 230 connected to both the sliding hole 240 and the mounting groove 210, the wedge-shaped end 332 is at least partially accommodated in the auxiliary groove 230, and the side away from the wedge-shaped portion 314 is slidably connected to the groove wall of the auxiliary groove 230 along the extension direction of the sliding hole 240, so as to guide the pushing block 330 to move along the extension direction of the sliding hole 240 under the push of the auxiliary tool 700.

[0067] Specifically, the first inclined surface 331 is located at the wedge-shaped end 332, and the wedge-shaped end 332 abuts against the second inclined surface 311 of the wedge-shaped portion 314 through the first inclined surface 331. The side of the wedge-shaped end 332 facing away from the first inclined surface 331 abuts against the groove wall of the auxiliary groove 230, and can move relative to the groove wall of the auxiliary groove 230 along the extension direction of the sliding hole 240, thereby limiting the position of the wedge-shaped end 332 and guiding the movement of the wedge-shaped end 332 along the extension direction of the sliding hole 240, so that the pushing block 330 is more stable under the push of the auxiliary tool 700.

[0068] See also Figure 6 , Figure 7 , Figure 8 and Figure 9 In one embodiment, the mounting groove 210 includes a mating groove 220 and a receiving groove 260 that are interconnected. The rotating member 110 is used to be inserted into the receiving groove 260 and at least partially abuts against the groove wall of the receiving groove 260. The clamping block 310 is at least partially accommodated in the mating groove 220. The side of the elastic member 320 facing away from the clamping block 310 is connected to the groove wall of the mating groove 220. The clamping block 310 is slidably connected to the groove wall of the mating groove 220 to guide the clamping block 310 to move toward the side away from the rotating member 110.

[0069] Specifically, the matching groove 220 is recessed on the groove wall of the installation groove 210 and communicates with the auxiliary groove 230. Since the clamping block 310 is slidably connected with the groove wall of the matching groove 220, the position of the clamping block 310 in the moving direction relative to the rotating member 110 is limited, so that the clamping block 310 can stably move relative to the rotating member 110 under the action of the pushing block 330, thereby improving the stability of the mechanism. The setting that the rotating member 110 at least partially abuts against the groove wall of the accommodating groove 260 improves the stability of the matching between the rotating member 110 and the installation groove 210 in the locked state, so that the rotating member 110 can drive the erecting platform 200 to rotate stably.

[0070] Furthermore, the first abutting surface 316 of the block 310 and one side of the slot near the mounting slot 210 abut against the two slot walls of the mating slot 220 in the third direction, thereby reducing interference with the wedge-shaped portion 314, allowing the wedge-shaped portion 314 to be stably mated with the wedge-shaped end 332. At the same time, the block 310 can be pushed by the pushing block 330 to stably move toward the side away from the rotating member 110, thereby improving the efficiency of converting the mechanism from a locked state to an unlocked state.

[0071] In addition, a guide groove 112 is provided on the rotating member 110 at a side of the slot 111 away from the slot of the installation slot 210 , thereby playing a guiding role when the rotating member 110 and the receiving slot 260 are inserted relative to each other.

[0072] See also Figure 7 and Figure 9, in one embodiment, a first step wall 231 is formed at the connection between the auxiliary slot 230 and the sliding hole 240. In the locked state, the end of the wedge end 332 away from the wedge portion 314 can abut against the first step wall 231.

[0073] Specifically, when the rotating member 110 is received in the installation slot 210, the locking block 310 will move toward the side away from the elastic member 320 under the push of the elastic member 320, and the wedge portion 314 will provide a reverse force to the wedge end 332, causing the wedge end 332 to move toward the side of the sliding hole 240. When the end of the wedge end 332 away from the wedge portion 314 abuts against the first step wall 231, it can limit the further movement of the locking block 310 toward the side away from the elastic member 320, preventing the excessive pressing force of the locking block 310 on the rotating member 110 from damaging the rotating member 110. At the same time, when the rotating member 110 is outside the installation slot 210, it can also limit the locking block 310 from disengaging from the fitting slot 220, improving the stability of the mechanism.

[0074] Refer to Figure 7 and Figure 9 , in one embodiment, the upright platform 200 is provided with an installation hole 250 communicating with the fitting slot 220. The installation hole 250 communicates with the outside and forms a second step wall 251 with the fitting slot 220. A cover plate 340 is provided in the installation hole 250. The cover plate 340 abuts against the second step wall 251 to form the wall of the fitting slot 220 for the connection of the side of the elastic member 320 away from the locking block 310. Among them, the cover plate 340 is detachably connected to the second step wall 251, facilitating the installation and disassembly of the elastic clamping member 300.

[0075] Refer to Figure 1 and Figure 5 , in one embodiment, the pliers lifting mechanism further includes a steel cable 120. One end of the steel cable 120 extends into the storage slot 410 and is connected to the rotating member 110. The steel cable 120 is configured to drive the rotating member 110 to rotate when being pushed or pulled.

[0076] Specifically, the rotating member 110 includes a rotating shaft 113 and a rotating block 114 connected to each other. The rotating block 114 is inserted into the receiving slot 260. The rotating shaft 113 is connected to the steel cable 120 and is rotatably connected to the wall of the storage slot 410. Thus, during the process of pushing or pulling the steel cable 120, the rotating member 110 can rotate stably, driving the upright platform 200 to rotate. Preferably, the rotating block 114 is a square block.

[0077] Refer to Figure 1 and Figure 5, in one embodiment, the transmission assembly 100 further includes a first connecting rod 130 and a second connecting rod 140. The first connecting rod 130 is connected to the rotating member 110. One end of the second connecting rod 140 is rotatably connected to the end of the first connecting rod 130 away from the rotating member 110, and the other end is connected to the steel cable 120. An operation hole 420 for the steel cable 120 to pass through is provided on the insertion portion 400, and the operation hole 420 is used to guide the steel cable 120.

[0078] Specifically, the arrangement of the steel cable 120 passing through the operation hole 420 can reduce the interference of the steel cable 120 on other structures. The first connecting rod 130 is connected to the rotating shaft 113, the second connecting rod 140 is rotatably connected to the first connecting rod 130, and the steel cable 120 is connected to the second connecting rod 140, which can form a crank-slider mechanism. When the steel cable 120 is pushed and pulled along the extending direction of the operation hole 420, the rotating member 110 can be driven, improving the stability of the mechanism.

[0079] Further, the end of the first connecting rod 130 away from the rotating shaft 113 extends radially to one side of the rotating shaft 113, thereby increasing the torque of the steel cable 120 on the rotating member 110, enabling the rotating member 110 to rotate with a relatively small acting force of the steel cable 120, and thus improving the service life of the steel cable 120.

[0080] Furthermore, a round hole 131 is provided on the side of the first connecting rod 130 away from the rotating shaft 113. A part of the second connecting rod 140 extends into the round hole 131 and is slidably connected to the hole wall of the round hole 131, thereby reducing the use of fixing parts such as screws.

[0081] Refer to Figure 1 , Figure 2 and Figure 5 , an endoscopic head end provided by an embodiment of the present invention further includes a head end seat 440 and the above-mentioned forceps lifting mechanism. The head end seat 440 is configured with a receiving groove 410 for the upright platform 200 to be inserted.

[0082] Specifically, the storage groove 410 includes a first accommodation cavity 411, a second accommodation cavity 413, and a third accommodation cavity 412 that are connected in sequence. The rotating shaft 113 is accommodated in the second accommodation cavity 413 and is rotatably connected to the cavity wall of the second accommodation cavity 413. The rotating block 114 is accommodated in the first accommodation cavity 411. The first connecting rod 130 and the second connecting rod 140 are arranged in the third accommodation cavity 412. The operation hole 420 communicates with the third accommodation cavity 412. In this application, in the locked state, the elastic clamping member 300 elastically abuts against the rotating member 110, thereby restricting the relative detachment of the rotating member 110 from the installation groove 210, so that the upright platform 200 can rotate synchronously with the rotating member 110. In the unlocked state, the elastic clamping member 300 releases the rotating member 110, enabling the rotating member 110 and the installation groove 210 to relatively move and disengage, thereby facilitating the disassembly of the upright platform 200 and the rotating member 110 and its detachment from the storage groove 410, further facilitating the cleaning of the upright platform 200 and the head end seat 440, reducing the cleaning difficulty, and reducing the time consumed by the disinfection operation.

[0083] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 9 , the embodiment of the present invention further provides an endoscope, including the above-mentioned forceps lifting mechanism in the insertion portion 400, and a storage groove 410 for inserting the upright platform 200 is formed at the head end of the insertion portion 400.

[0084] Specifically, in this application, in the locked state, the elastic clamping member 300 elastically abuts against the rotating member 110, thereby restricting the relative detachment of the rotating member 110 from the installation groove 210, so that the upright platform 200 can rotate synchronously with the rotating member 110. In the unlocked state, the elastic clamping member 300 releases the rotating member 110, enabling the rotating member 110 and the installation groove 210 to relatively move and disengage, thereby facilitating the disassembly of the upright platform 200 and the rotating member 110 and its detachment from the storage groove 410, further facilitating the cleaning of the upright platform 200 and the insertion portion 400, reducing the cleaning difficulty, and reducing the time consumed by the disinfection operation.

[0085] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
