DETAILED DESCRIPTION

[0016] In order to more clearly illustrate the technical solutions of the embodiments of the present specification, the drawings needed in the embodiment description will be briefly introduced below. Obviously, the drawings in the following description are only some examples or embodiments of the present specification, and those skilled in the art can also apply the present specification to other similar scenarios without creating any creative labor, based on these drawings. Unless it is clear from the language environment or otherwise stated, the same reference numbers in the drawings represent the same structure or operation.

[0017] Those skilled in the art can understand that the terms "first", "second", etc. in the present specification are only used to distinguish different devices, modules or parameters, etc., and do not represent any specific technical meaning, nor do they represent the inevitable logical sequence between them.

[0018] As shown in the specification and claims, unless the context clearly indicates otherwise, the words "one", "a", "an", and / or "the" do not refer to the singular, but can also include the plural. Generally speaking, the terms "comprise" and "include" only indicate the inclusion of the steps and elements explicitly identified, and these steps and elements do not constitute an exclusive list, and the method or device can also include other steps or elements.

[0019] The present specification covers the substitutions, modifications, equivalent methods and solutions made on the essence and scope of the present specification defined by the claims. Further, in order to make the public have a better understanding of the present specification, some specific details are described in the following detailed description of the present specification. The present specification can also be fully understood without the description of these details by those skilled in the art.

[0020] Figure 1 is a cross-sectional schematic view of a buckle structure according to some embodiments of the present specification; Figure 2 is a cross-sectional schematic view of a second connecting part and an unlocking assembly of a buckle structure according to some other embodiments of the present specification. As Figure 1 and Figure 2 shown, in some embodiments, the buckle structure 10 can include a first connecting part 11, a second connecting part 12 and an unlocking assembly 13. The first connecting part 11 can include a first clamping piece 111 and a second clamping piece 112, which are arranged at intervals along a first direction. The first clamping piece 111 and the second clamping piece 112 are each provided with a clamping groove 113, and the clamping groove 113 of the first clamping piece 111 is oppositely arranged with the clamping groove 113 of the second clamping piece 112. The second connecting part 12 is provided with two clamping platforms 121, which are arranged at intervals along the first direction. The unlocking assembly 13 can include a first release button 131 and a second release button 132. The first release button 131 and the second release button 132 are the same in structure, and the first release button 131 and the second release button 132 can cooperate with each other to be movable (e.g., moving towards each other or moving away from each other) in the first direction. When the two clamping platforms 121 are located between the first clamping piece 111 and the second clamping piece 112, the two clamping platforms 121 can be clamped into the clamping groove 113 of the first clamping piece 111 and the clamping groove 113 of the second clamping piece 112, respectively. When the first release button 131 and the second release button 132 are pressed and move towards each other in the first direction, the first clamping piece 111 and the second clamping piece 112 can be pushed to move away from each other in the first direction, so that the two clamping platforms 121 are respectively disengaged from the clamping groove 113 of the first clamping piece 111 and the clamping groove 113 of the second clamping piece 112. Wherein, the first direction can be represented by the arrow X in Figure 1 and Figure 2 . The oppositely arranged clamping grooves 113 of the first clamping piece 111 and the second clamping piece 112 can mean that the heights of the two clamping grooves 113 are the same, and the height of the clamping groove 113 can mean the position of the clamping groove 113 in a second direction. The second direction can be represented by the arrow Z in Figure 1 and Figure 2 .

[0021] In some embodiments, the buckle structure 10 can be applied to scenarios where two components need to be connected or separated. For example, to connect two components, the first connecting part 11 can be arranged on one component, and the second connecting part 12 can be arranged on the other component. The connection of the first connecting part 11 and the second connecting part 12 can be achieved by inserting the two clamping posts 121 on the second connecting part 12 into the clamping grooves 113 of the first clamping member 111 and the second clamping member 112, respectively, thereby achieving the connection of the two components. In some specific embodiments, the buckle structure 10 can be applied to medical instruments used by doctors during clinical surgery or examination. For example, during clinical surgery, doctors may perform a series of actions such as cutting, coagulation, suturing, and knotting according to different situations, which requires the use of different medical instruments. Therefore, whether the medical instruments can be quickly and conveniently replaced will directly affect the smoothness of the entire surgical process and the length of the surgery.

[0022] In some cases, when connecting or separating two components using the buckle structure 10 provided in the present specification, the entire process can be completed by a single hand, which is more convenient and efficient, improves the smoothness of the surgery, and shortens the length of the surgery. For example, when connecting, only one hand is needed to control the movement of the component provided with the second connecting part 12, so that the two clamping posts 121 are inserted into the clamping grooves 113 of the first clamping member 111 and the second clamping member 112, respectively. For another example, when separating, only one hand is needed to press the first release button 131 and the second release button 132 to move them in the first direction towards each other, so as to push the first clamping member 111 and the second clamping member 112 away from the two clamping posts 121. In other cases, the unlocking assembly 13 of the buckle structure 10 includes the first release button 131 and the second release button 132, which are the same in structure. The two release buttons are connected in a specific manner, so that the overall structure of the unlocking assembly 13 is more compact.

[0023] In some embodiments, the first clamping member 111 and the second clamping member 112 can be clamping rings. For example, in the embodiment shown in FIG. 1, the first clamping member 111 and the second clamping member 112 are ear-shaped clamping rings. Figure 8 In order to enable the first clamping member 111 and the second clamping member 112 to be pushed away from the two clamping posts 121 by the first release button 131 and the second release button 132, in some embodiments, the first clamping member 111 and the second clamping member 112 can be made of materials with certain elastic deformation ability and strength. The types of materials can include ABS plastic (e.g., acrylonitrile, butadiene, styrene) and POM plastic (e.g., polyoxymethylene resin).

[0024] Figure 3is a structural schematic view of a first release button and a second release button in a non-pressed state according to some embodiments of the present specification; Figure 4 is a structural schematic view of a first release button and a second release button in a pressed state according to some embodiments of the present specification; Figure 5 is a structural schematic view of a substrate according to some embodiments of the present specification. As shown in Figures 1 to 5 , in some embodiments, the unlocking assembly 13 can further include a substrate 137, and the two card platforms 121 can be disposed on the substrate 137. For example, the two card platforms 121 can be respectively disposed at opposite positions on the outer side of the substrate 137, and when the first connecting portion and the second connecting portion are fitted, the first clamping member 111 and the second clamping member 112 can be respectively clamped into the outer side of the substrate 137 and fitted with the two card platforms 121 on the outer side of the substrate 137.

[0025] As shown in Figure 1 and Figure 2 , in some embodiments, the outer side wall of each card platform 121 (i.e., the side wall of the card platform 121 away from the other card platform 121) is a bevel. For example, the card platform 121 on the right side in Figure 1 and Figure 2 extends in a direction away from the left card platform 121. The thickness (i.e., the dimension in the second direction) of the protruding portion of the card platform 121 gradually increases along the first direction from right to left, so that the outer side wall of the card platform 121 is inclined upward to form a bevel. During the fitting of the first connecting portion 11 and the second connecting portion 12, when the first clamping member 111 and the second clamping member 112 abut against the bevel, the first clamping member 111 and the second clamping member 112 will elastically deform, and the first clamping member 111 and the second clamping member 112 will continuously move along the bevel, so that the elastic deformation of the first clamping member 111 and the second clamping member 112 continuously increases, until the protruding portion of the card platform 121 is clamped into the clamping groove 113 of the first clamping member 111 and the clamping groove 113 of the second clamping member 112.

[0026] In some embodiments, the angle between the extension direction of the bevel of the card platform 121 and the second direction can be between 10 degrees and 30 degrees. In some embodiments, the angle between the extension direction of the bevel and the second direction is between 15 degrees and 25 degrees. In some embodiments, the angle between the extension direction of the bevel and the second direction can be 22 degrees.

[0027] As shown in Figures 1 to 5As shown in FIG. 1, in some embodiments, two mating holes 1371 are arranged on the substrate 137, and the two mating holes 1371 are arranged on two sides of the substrate 137 along the first direction, and the positions of the two mating holes 1371 correspond to the positions of the first clamping member 111 and the second clamping member 112, so that the first clamping member 111 and the second clamping member 112 can respectively extend into the two mating holes 1371. The inner side of each mating hole 1371 (i.e. the side of the mating hole 1371 close to the other mating hole 1371) is respectively provided with a clamping post 121. During the mating of the first connecting part 11 and the second connecting part 12, the first clamping member 111 and the second clamping member 112 can respectively extend into the two mating holes 1371 and abut against the corresponding clamping post 121, so that the two clamping posts 121 are respectively clamped into the clamping groove 113 of the first clamping member 111 and the clamping groove 113 of the second clamping member 112.

[0028] Figure 6 FIG. 1 is a structural schematic view of the first release button or the second release button according to some embodiments of the present specification; Figure 7 FIG. 2 is a structural schematic view of the first release button or the second release button at another angle according to some embodiments of the present specification. FIG. 2 is combined with FIG. 1 to show the structure of the first release button or the second release button. Figures 1 to 7 As shown in FIG. 1, in some embodiments, the first release button 131 and the second release button 132 can each include a pressing member 133 and an abutting plate 134 connected with the pressing member 133. The pressing member 133 can include a pressing side 1331 and a connecting side 1332 arranged opposite to each other along the first direction. The abutting plate 134 can extend along the first direction, one end of the abutting plate 134 is connected with the connecting side 1332, and the other end of the abutting plate 134 is provided with a first abutting portion 1343. When the first release button 131 and the second release button 132 move towards each other along the first direction, the first abutting portion 1343 of the first release button 131 abuts against the side of the second clamping member 112 close to the first clamping member 111, and the first abutting portion 1343 of the second release button 132 can abut against the side of the first clamping member 111 close to the second clamping member 112.

[0029] In the present embodiment, the pressing side 1331 can be used for being pressed by an operator (for example, a doctor). When the pressing side 1331 is pressed, the connecting side 1332 and the abutting plate 134 connected with the connecting side 1332 will move along the first direction. When the pressing side 1331 of the first release button 131 and the pressing side 1331 of the second release button 132 are simultaneously pressed, the first release button 131 and the second release button 132 will move towards each other, so that the two first abutting portions 1343 abut against the first clamping member 111 and the second clamping member 112 respectively, and then the first clamping member 111 and the second clamping member 112 are elastically deformed and separated from the two clamping posts 121. Figure 1 and Figure 2The abutting plate 134 of the first release button 131 moves rightward in the first direction, and the abutting plate 134 of the second release button 132 moves leftward in the first direction. When the first release button 131 and the second release button 132 are pressed to a sufficient depth, the first abutting portion 1343 of the first release button 131 abuts against the inner side of the second clamping member 112 (i.e., the side of the second clamping member 112 close to the first clamping member 111), and the first abutting portion 1343 of the second release button 132 abuts against the inner side of the first clamping member 111 (i.e., the side of the first clamping member 111 close to the second clamping member 112). The abutting here can mean that the first abutting portion 1343 and the clamping member are in contact with each other, and the first abutting portion 1343 applies a force to the clamping member. Since the first clamping member 111 and the second clamping member 112 are elastic, under the action of the force of the first abutting portion 1343, the first clamping member 111 and the second clamping member 112 are elastically deformed and gradually pushed open by the first abutting portion 1343, so that the clamping platform 121 is separated from the two clamping grooves 113.

[0030] In some embodiments, in order to improve the use experience of the operator, the pressing side 1331 can be provided with a concave surface, which is more suitable for the shape of the finger.

[0031] In combination Figures 1 to 5 As shown, in some embodiments, the abutting plate 134 can include a first plate body 1341 and a second plate body 1342. One end of the first plate body 1341 is connected to the connecting side 1332, and the other end of the first plate body 1341 is connected to one end of the second plate body 1342. The other end of the second plate body 1342 is provided with a first abutting portion 1343. The position of the lower surface of the first plate body 1341 is higher than the position of the upper surface of the second plate body 1342. Among them, the first plate body 1341 of the first release button 131 is located above the second plate body 1342 of the second release button 132, and the first plate body 1341 of the second release button 132 is located above the second plate body 1342 of the first release button 131. In this embodiment, when the first release button 131 and the second release button 132 are pressed, the first plate body 1341 of the first release button 131 and the second plate body 1342 of the second release button 132 move in the first direction relative to each other, and the first plate body 1341 of the second release button 132 and the second plate body 1342 of the first release button 131 move in the first direction relative to each other. Among them, the first plate body 1341 and the second plate body 1342 of the first release button 131 move rightward in the first direction, and the first plate body 1341 and the second plate body 1342 of the second release button 132 move leftward in the first direction, and finally the first abutting portion 1343 of the first release button 131 and the first abutting portion 1343 of the second release button 132 move in opposite directions in the first direction.

[0032] As shown in Figures 1 to 5 some embodiments, the other end of the first plate body 1341 can be provided with a notch 13411. The notches 13411 of the first release button 131 and the second release button 132 are matched to form a limiting hole 13412. The buckle structure 10 can further include a mounting piece 14 provided on the second connecting portion 12. The pressing pieces 133 of the first release button 131 and the second release button 132 are respectively provided on both sides of the mounting piece 14 along the first direction. The mounting piece 14 can include a pressing table 141 and a connecting column 142, the pressing table 141 is above and below the first release button 131 and the second release button 132 respectively, and the upper end of the connecting column 142 is connected with the pressing table 141, and the lower end of the connecting column 142 is connected with the base plate 137.

[0033] In the present embodiment, the limiting hole 13412 is formed by the notches 13411 of the first release button 131 and the second release button 132. Then, the connecting column 142 of the mounting piece 14 passes through the limiting hole 13412 to be connected with the base plate 137 and the pressing table 141 respectively, so that the first release button 131 and the second release button 132 are located between the pressing table 141 and the base plate 137, and the first release button 131 and the second release button 132 are effectively limited to move upward along the second direction by the pressing table 141. Wherein, moving upward along the second direction can mean moving away from the base plate 137 along the second direction. For example, in the embodiment shown in Figures 2 to 4 Since the pressing table 141 is supported on the base plate 137 by the connecting column 142, the height of the pressing table 141 remains unchanged. Therefore, the pressing table 141 can limit the first release button 131 and the second release button 132 to move upward along the second direction by abutting against the first plate body 1341 and the second plate body 1342.

[0034] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 4 The buckle structure 10 can further include a support table 16, which can be used to support the first release button 131 and the second release button 132, and prevent the first release button 131 and the second release button 132 from moving downward along the second direction. In some embodiments, the support table 16 can be provided on the base plate 137. Wherein, moving downward along the second direction can mean moving close to the base plate 137 along the second direction.

[0035] In some embodiments, a plurality of pairs of support tables 16 can be provided on the base plate 137, each pair of support tables 16 is symmetrically provided on the left and right sides of the first release button 131 and the second release button 132 along the first direction, so as to ensure the balance of the first release button 131 and the second release button 132. For example, in the embodiment shown inFigure 3 And Figure 4 In the embodiment shown in FIG. 1 1, two pairs of support tables 16 are provided. One of the support tables 16 in the right pair of support tables 16 occupies less space than the other support tables 16, and the space left over can be used to provide other components.

[0036] In some embodiments, the support tables 16 are also provided with stop portions 161, which can be used to limit the movement of the first release button 131 and the second release button 132 in a third direction. The third direction can be represented by the arrow Y in FIG. 1 1. In some embodiments, the first direction, the second direction, and the third direction can be three mutually perpendicular directions. Figure 3

[0037] As shown in FIG. 1 1, in some embodiments, the stop portions 161 are provided on each of the support tables 16. The inner side walls of the stop portions 161 (i.e., the side of one of the support tables 16 that is closer to the stop portion 161 of the other support table 16 in the pair of support tables 16) can abut the side walls of the first plate body 1341 and the second plate body 1342 to limit the movement of the first release button 131 and the second release button 132. Figure 3 Figure 4

[0038] In some embodiments, the stop portions 161 can be independent of the support tables 16. For example, the stop portions 161 can include stop pieces provided on the base plate 137, such as stop pieces provided on both sides of the first plate body 1341 and the second plate body 1342 in the first direction, and the inner side walls of the stop pieces can abut the side walls of the first plate body 1341 and the second plate body 1342.

[0039] In combination with Figure 1 Figure 2 ​​​​As shown, in some embodiments, the unlocking assembly 13 can further include a first elastic member 138 and a second elastic member 139. The first elastic member 138 is arranged between the pressing platform 141 and the connecting side 1332 of the first release button 131, and the second elastic member 139 is arranged between the pressing platform 141 and the connecting side 1332 of the second release button 132. When the first release button 131 and the second release button 132 move towards each other in the first direction, the first elastic member 138 and the second elastic member 139 are compressed. In this embodiment, when the two pressing members 133 are pressed to cause the first release button 131 and the second release button 132 to move towards each other, the first elastic member 138 and the second elastic member 139 will be compressed to generate an elastic restoring force due to the position of the pressing platform 141 remaining unchanged. After the external pressing force is removed, the elastic restoring force can cause the first release button 131 and the second release button 132 to move away from each other in the first direction to return to the initial position. The initial position can refer to the position of the first release button 131 and the second release button 132 when they are not pressed, for example, when the two pressing members 133 are not pressed. Figure 1 In the embodiment shown, the position of the first release button 131 and the second release button 132 can be considered as the initial position.

[0040] In some embodiments, the connecting side 1332 of each pressing member 133 is provided with a mounting column 135, and the pressing platform 141 is provided with a mounting hole 1411 corresponding to the two connecting sides 1332. The mounting hole 1411 and the mounting column 135 can be used to fix the first elastic member 138 and the second elastic member 139, reducing the amplitude of the shaking of the first elastic member 138 and the second elastic member 139 during movement. For example, as shown, the mounting column 135 of the connecting side 1332 of the first pressing member 133 is arranged in the mounting hole 1411 of the pressing platform 141. Figure 1 As shown, taking the first elastic member 138 (on the left side) as an example, one end of the first elastic member 138 is sleeved on the mounting column 135 of the connecting side 1332 of the first release button 131, and the other end is located in the mounting hole 1411 of the pressing platform 141.

[0041] In some embodiments, the first release button 131 and the second release button 132 can each further include a reinforcing rib 136. The reinforcing rib 136 can be arranged between the connecting side 1332 of the first release button 131 and the connecting side 1332 of the second release button 132 and the first plate body 1341 to ensure that the first release button 131 and the second release button 132 have a certain rigidity. For example, as shown, the reinforcing rib 136 is arranged on the connecting side 1332 of the first release button 131 and the connecting side 1332 of the second release button 132. Figures 1 to 7 In the embodiment shown, two reinforcing ribs 136 are arranged on the connecting side 1332 of each pressing member 133, and the two reinforcing ribs 136 are arranged on both sides of the mounting column 135 to connect the connecting side 1332 of the pressing member 133 and the first plate body 1341.

[0042] In some embodiments, the other end of the second plate body 1342 is further provided with a second abutting portion 1346, which is located above the first abutting portion 1343. When the first release button 131 and the second release button 132 move towards each other in the first direction, the second abutting portion 1346 of the first release button 131 can abut against the pressing piece 133 of the second release button 132. The second abutting portion 1346 of the second release button 132 can abut against the pressing piece 133 of the first release button 131. In the present embodiment, by providing the second abutting portion 1346, when the first release button 131 and the second release button 132 are pressed and move towards each other in the first direction, the second abutting portion 1346 can abut against the pressing piece 133 of the first release button 131 and the pressing piece 133 of the second release button 132 respectively, so as to limit the depth (distance of movement in the first direction) of the pressing piece 133 of the first release button 131 and the pressing piece 133 of the second release button 132 being pressed.

[0043] In some embodiments, the first abutting portion 1343 can include a first abutting surface 13431, and the second abutting portion 1346 can include a second abutting surface 13461, and the first abutting surface 13431 can be parallel to the second abutting surface 13461. For example, as shown in Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , the first abutting portion 1343 can include an extension boss arranged below the other end of the second plate body 1342, the extension boss protrudes from the other end of the second plate body 1342 in the first direction, and the first abutting surface 13431 can refer to the end surface of the extension boss away from the first plate body 1341. The second abutting portion 1346 can include the end of the other end of the second plate body 1342, and the second abutting surface 13461 can refer to the end surface of the other end of the second plate body 1342. In the present embodiment, since the first abutting portion 1343 protrudes from the other end of the second plate body 1342 (i.e. the second abutting portion 1346) in the first direction, the first abutting surface 13431 and the second abutting surface 13461 are located in different planes respectively, so that when the pressing piece 133 abuts against the second abutting portion 1346, the first abutting portion 1343 abutting against the first clamping piece 111 and the second clamping piece 112 will not be affected.

[0044] For example, as shown in Figure 5As shown, in some embodiments, two limiting blocks 15 are arranged on the first connecting portion 11, and the two limiting blocks 15 are arranged in the first direction and are located between the first abutting portion 1343 of the first release button 131 and the first abutting portion 1343 of the second release button 132. The first abutting portion 1343 of the first release button 131 is in abutment with one limiting block 15 under the elastic restoring force of the first elastic member 138, and the first abutting portion 1343 of the second release button 132 is in abutment with the other limiting block 15 under the elastic restoring force of the second elastic member 139. In the embodiment, by arranging the limiting blocks 15 on the first connecting portion 11, when the first abutting portions 1343 of the two release buttons move towards each other in the first direction, the outer side walls of the two limiting blocks 15 (i.e., the side of one limiting block 15 away from the other limiting block 15) can be in abutment with the two first abutting portions 1343 (for example, in Figure 3 and Figure 4 As shown in the embodiment, the first abutting portion 1343 of the first release button 131 is in abutment with the outer side wall of the limiting block 15 on the left, and the first abutting portion 1343 of the second release button 132 is in abutment with the outer side wall of the limiting block 15 on the right) to limit the distance of the first release button 131 and the second release button 132 moving away from each other under the elastic restoring force.

[0045] In combination Figures 1 to 7 As shown, in some specific embodiments, the first abutting portion 1343 can include a third abutting surface 13432 arranged on the end face of the extending protrusion close to one end of the first plate body 1341. When the first release button 131 and the second release button 132 move away from each other to a certain distance under the elastic restoring force of the first elastic member 138 and the second elastic member 139, respectively, the third abutting surface 13432 of the first release button 131 and the third abutting surface 13432 of the second release button 132 will be in abutment with the outer side walls of the two limiting blocks 15, respectively.

[0046] In some embodiments, the two limiting blocks 15 can be arranged on the base plate 137, for example, in the embodiments shown in Figure 1 and Figure 2 The two limiting blocks 15 are arranged on the two sides of the base plate 137 in the first direction, respectively. In some specific embodiments, the limiting block 15 can have a plate structure, and the outer side wall surface of the plate structure is parallel to the third abutting surface 13432, so as to facilitate the closer fit of the limiting block 15 and the third abutting surface 13432 when they are in abutment.

[0047] In some embodiments, the supporting block 16 can be connected with the limiting block 15. For example, in Figure 5In the illustrated embodiment, one of the support tables 16 in each pair is connected to the limiting table 15. In some alternative embodiments, the support table 16 and the limiting table 15 can be integrally formed.

[0048] As shown in FIG. 1, in some embodiments, the first release button 131 and the second release button 132 are connected to each other. In some embodiments, the first release button 131 and the second release button 132 are connected to each other through a first plate body 1341 and a second plate body 1342. The first plate body 1341 and the second plate body 1342 are connected to each other through a hinge 1343. The hinge 1343 can be a living hinge. In some embodiments, the hinge 1343 can be a hinge structure formed by a plurality of living hinges. Figure 6 Figure 7 As shown in FIG. 1, in some embodiments, the first release button 131 and the second release button 132 are connected to each other. In some embodiments, the first release button 131 and the second release button 132 are connected to each other through a first plate body 1341 and a second plate body 1342. The first plate body 1341 and the second plate body 1342 are connected to each other through a hinge 1343. The hinge 1343 can be a living hinge. In some embodiments, the hinge 1343 can be a hinge structure formed by a plurality of living hinges.

[0049] In some embodiments, the width of the sliding block 1344 can be the same as the width of the limiting track 1345, so that when the sliding block 1344 is located in the limiting track 1345, the limiting track 1345 and the sliding block 1344 can abut each other to limit the relative movement of the first release button 131 and the second release button 132 in the third direction. The width can refer to the size of the sliding block 1344 and the limiting track 1345 in the third direction.

[0050] In some embodiments, the limiting track 1345 of the first release button 131 and the limiting track 1345 of the second release button 132 are each provided with a limiting piece, which can abut the sliding block 1344 to limit the range of movement of the sliding block 1344 along the limiting track 1345, thereby limiting the movable range of the first release button 131 and the second release button 132 in the first direction. In some specific embodiments, a limiting piece can be arranged at each end of each limiting track 1345 in the first direction, so that when the first release button 131 and the second release button 132 are connected, the sliding block 1344 is located between the two limiting pieces, thereby limiting the range of movement of the first release button 131 and the second release button 132 in the first direction.

[0051] Figure 8 is a structural schematic diagram of a medical device according to some embodiments of the present specification. As shown in FIG. 1,​Figure 8 As shown, the present specification also provides a medical device 100, comprising a base 30 and a medical instrument 20.
