Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a mounting device for an end guide. Background Art

[0002] With the promotion of orthopedic surgical robots in hospitals, the application of surgical robots to assist surgery has become more and more widespread. The end guide, as an important component of the surgical robot, is mainly used to provide guidance and positioning functions for the sleeve or Kirschner wire. During normal use, the end guide needs to be disassembled after each operation, and the end guide needs to be disinfected and sterilized before the operation begins before being installed on the robotic arm. Therefore, the end guide usually needs to meet the following requirements: 1. It can be easily and quickly installed on the visual tracker without any disassembly tools; 2. After installation, it is firm and reliable, with high stability to ensure system accuracy.

[0003] In the document with publication number CN115227405A and invention name "end guide", it is recorded that when unlocking, its implementation method is as follows: Figure 1 As shown, the pulling end 1172 of the unlocking member 117 is rotated to a vertical position to release the tension on the locking and unlocking shaft 113, and the tension spring 1133 retracts under the action of its own elastic force, driving the locking and unlocking shaft 113 to move upward, so that its lower part is in the same horizontal plane as the sliding member 115 and the unlocking end 1143 at the lower end of the buckle 114, so that the sliding member 115 has sliding space, so that the unlocking button 116 can be pressed, thereby driving the unlocking end 114 at the lower end of the buckle to move inward, so that the locking end of the buckle 114 rotates outward, thereby releasing the adapter 111.

[0004] However, the above structure still has the following problems. During the unlocking process, not only the unlocking member 117 needs to be operated to move, but also the unlocking button 116 needs to be operated to move. At least two parts of operation are required to achieve the unlocking between the quick release member and the adapter. The operation is cumbersome and not conducive to the rapid disassembly of the end guide. Utility Model Content

[0056] Figure 2 1 is a schematic diagram of the installation of the end guide provided in the embodiment of the present application, which is to install the end guide 10 at the end of the end tracker 30 or the end of the robot arm 20 by quick release, while also ensuring the installation stability of the end guide 10. The embodiment of the present application provides an installation device for the end guide, Figure 3 It is a schematic diagram of the overall structure of the installation device of the end guide provided in the embodiment of the present application; Figure 4 This is one of the exploded structural schematic diagrams of the installation device of the end guide provided in the embodiment of the present application; Figure 5 This is the second schematic diagram of the exploded structure of the installation device of the end guide provided in the embodiment of the present application. Figures 3 to 5 As shown, the installation device may include an adapter assembly 200 and a fixing assembly 300; the adapter assembly 200 can be fixed to the end of the previous structure by means of bolts, bonding, etc., but the outer end face of the adapter assembly 200, that is, the end face that will dock with the fixing assembly 300, is provided with a connecting portion 210, and the connecting portion 210 can be quickly disconnected from the fixing assembly 300, thereby achieving the purpose of fixing the end guide 10 to the adapter assembly 200.

[0057] The fixing assembly 300 is provided with an end guide, and the fixing assembly 300 includes an operating component 310, a transmission component 320 and a locking component 330 which are sequentially connected in a transmission manner. The operating component 310 can adjust the posture so that the transmission component 320 drives the locking component 330 to move, so that the locking component 330 locks the connection part 210 or releases the connection part 210.

[0058] It can be understood that for ease of description, the fixing assembly 300 and the end guide structure are separated. Of course, the fixing assembly 300 and the end guide can be two-part structures, which are connected into a whole by welding, bolting, etc. It can also be understood that the fixing assembly 300 in this example is combined with the end guide in a manner that includes an integral formation to enhance the connection firmness of the fixing assembly 300 and the end guide.

[0059] In this example, the locking between the locking component 330 and the connecting portion 210 includes a snap-on method, for example, the locking between the two can be achieved by extending the snap into the snap-on groove 211. If unlocking is required, the snap is separated from the snap-on groove 211. The snap can be provided on the connecting portion 210, and the snap-on groove 211 is correspondingly formed on the locking component 330. Of course, the snap can also be provided on the locking component 330, and the snap-on groove 211 is correspondingly formed on the connecting portion 210.

[0060] Regardless of the above-mentioned configuration, the relative position of the buckle and the clamping groove 211 needs to be changed to achieve locking or releasing of the connection part 210 by the locking component 330. Since the structure of the connection part 210 is mainly simple, it is convenient to wipe and disinfect before use. Therefore, it is necessary to facilitate the movement of the locking component 330 to achieve locking or releasing of the connection part 210.

[0061] In order to realize multiple redirection transmission of force, this example sets up an operating component 310, a transmission component 320 and a locking component 330 which are sequentially connected in transmission. It is only necessary to adjust the posture of the operating component 310 to drive the transmission component 320 and the locking component 330 to move accordingly. That is, the operating component 310 can have a locking posture and an unlocking posture, and in the locking posture and the unlocking posture, the movement directions of the transmission component 320 and the locking component 330 are different, so as to achieve the purpose of the locking component 330 locking the connection part 210 or releasing the connection part 210.

[0062] The transmission component 320 is used to change the direction of force transmission to drive the locking component 330 to move closer to the connecting portion 210 , or to drive the locking component 330 to move away from the connecting portion 210 .

[0063] In the present application, in order to achieve the locking or releasing of the locking component 330 in the fixing assembly 300 and the connecting part 210 in the adapter assembly 200, the locking component 330 is connected by sequentially transmitting the operating component 310 and the transmission component 320, and only by controlling the posture of the operating component 310 and changing the transmission direction of the force in combination with the transmission component 320, the purpose of moving the locking component 330 toward the connecting part 210 or away from the connecting part 210 can be achieved. This setting can achieve the release of the connecting part 210 by the locking component 330 through, for example, manual operation of the operating component 310, which is more convenient and conducive to the rapid disassembly of the end guide.

[0064] Figure 6 It is one of the structural schematic diagrams of the installation device provided in the embodiment of the present application in the locked position; Figure 7 is a schematic diagram of the structure of the installation device provided in an embodiment of the present application; Figure 8 This is the second structural schematic diagram of the installation device provided in the embodiment of the present application in the unlocked position; Fig. 9 It is a schematic diagram of the structure of the installation device provided in an embodiment of the present application. Fig.10 is a schematic diagram of the structure of a locking component provided in an embodiment of the present application; Fig.11 is a structural schematic diagram of a first transmission member provided in an embodiment of the present application; Fig.12 is a structural schematic diagram of a second transmission member provided in an embodiment of the present application; Fig.13 It is a schematic diagram of the structure of the operating component provided in the embodiment of the present application.

[0065] Next, we will combine the attached Figure 3 -Attached Fig.13 The specific structure of the installation device of the end guide provided in the embodiment of the present application is described in detail.

[0066] like Figure 7 and Fig. 9 As shown, in some embodiments, the locking component 330 includes a locking portion 331, and the locking portion 331 is suitable for being adapted to be engaged with the connecting portion 210; the operating component 310 is suitable for switching between an unlocked position and a locked position, and in the process of switching from the unlocked position to the locked position, the locking portion 331 is driven to move forward so that the locking portion 331 is engaged with the connecting portion 210; in the process of switching from the locked position to the unlocked position, the locking portion 331 is driven to move reversely so that the locking portion 331 releases the connecting portion 210.

[0067] Specifically, the manner in which the locking portion 331 and the connecting portion 210 are adapted and snapped together can be understood as a snapping manner in which the buckle is inserted into the snapping groove 211, which can achieve effective connection between the locking portion 331 and the connecting portion 210. However, in order to prevent the locking portion 331 from loosening during the snapping process with the connecting portion 210, it is necessary to hard-drive the operating component 310, the transmission component 320, and the locking component 330. In other words, any change in the posture of the operating component 310 will affect the change in the position of the terminal locking portion 331.

[0068] In order to more clearly understand the transmission relationship between the operating component 310 and the locking portion 331, the posture of the operating component 310 is defined to include an unlocking position and a locking position. When the operating component 310 is in the unlocking position, the locking portion 331 releases the connecting portion 210; when the operating component 310 is in the locking position, the locking portion 331 locks the connecting portion 210. The locking portion 331 includes forward movement and reverse movement, and the forward movement or reverse movement may include forward movement, reverse movement, or forward rotation, reverse rotation.

[0069] The movement mode of the locking portion 331 can be that when the operating member 310 switches from the unlocking position to the locking position, the transmission member 320 moves, thereby driving the locking portion 331 to move in the positive direction, that is, the locking portion 331 moves as a whole in the direction close to the connecting portion 210, so as to achieve effective engagement between the locking portion 331 and the connecting portion 210, and vice versa. Alternatively, when the operating member 310 switches from the unlocking position to the locking position, the transmission member 320 moves, but drives the locking portion 331 to rotate in the positive direction, that is, the locking portion 331 also rotates to the connecting portion 210, so as to achieve effective engagement between the locking portion 331 and the connecting portion 210, and vice versa.

[0070] It should be noted that when the operating component 310 is continuously located at the locking position, the locking portion 331 will also continue to be engaged with the connecting portion 210 , thereby ensuring the stability of the connection between the locking portion 331 and the connecting portion 210 .

[0071] To further understand the transmission between the locking component 330 and the transmission component 320, as shown in FIG. Figure 6 and Figure 8 As shown, in some embodiments, the locking component 330 further includes a transmission portion 332 disposed opposite to the locking portion 331 , and the transmission portion 332 is configured to drive the locking portion 331 to move forward or reversely under the drive of the transmission component 320 .

[0072] Specifically, the transmission part 332 and the locking part 331 can be rigidly connected or formed in one piece. The transmission part 332 and the locking part 331 are located at opposite ends. The locking part 331 is used to directly contact the connection part 210, and the transmission part 332 is used to directly contact the transmission component 320, so as to move with the movement of the transmission component 320, thereby driving the locking part 331 to move. For example, the transmission part 332 and the locking part 331 form a connecting rod, and the end of the connecting rod has a bend that is engaged with the connection part 210. The connection part 210 is a clamping groove 211 formed in the adapter assembly 200. The end of the connecting rod is connected to the transmission assembly, and the transmission assembly can move linearly. With the movement of the transmission assembly, the connecting rod can be driven to move in the direction of approaching / moving away from the adapter assembly 200, so that the bend extends into / out of the clamping groove 211, so as to achieve the purpose of locking the connection part 210 or releasing the connection part 210 by the locking part 331.

[0073] In addition to the above-mentioned method of making the locking portion 331 translate to lock the connecting portion 210, Figure 4 and Figure 5 As shown, in some embodiments, the fixing assembly 300 also includes a mounting base 340, and the locking component 330 is disposed on the mounting base 340 via a rotating shaft 333; the rotating shaft 333 is located between the locking portion 331 and the transmission portion 332, and the transmission portion 332 can rotate forward / reversely under the drive of the transmission component 320 to drive the locking portion 331 to rotate forward / reversely.

[0074] Specifically, the mounting base 340 is used to mount the above-mentioned operating component 310, transmission component 320 and locking component 330. The locking part 331 and the transmission part 332 of the locking component 330 are arranged on the mounting base 340 through the rotating shaft 333, that is, the locking part 331 can rotate along the rotating shaft 333 under the drive of the transmission part 332. Figure 3 and Figure 4As shown, in one example, the adapter assembly 200 includes a body 220 , and the connecting portion 210 is a snap-fitting groove 211 formed on the body 220 ; the locking portion 331 includes a buckle that can be adapted to snap-fit ​​with the snap-fitting groove 211 .

[0075] Specifically, an annular block, a semi-annular block or two symmetrical semi-annular blocks may be provided on the exposed surface of the body 220 to form a snap-fit ​​groove 211 between the annular block and the body 220 . The formation method of the snap-fit ​​groove 211 is not limited herein.

[0076] In order to achieve effective engagement between the locking portion 331 and the engaging groove 211, it can be designed as an L-shaped connecting rod, one end of which is connected to the transmission portion 332, and the other end of which can extend into the engaging groove 211. The transmitting portion 332 can rotate forward or reversely under the drive of the transmission component 320. Since the transmitting portion 332 is connected to the locking portion 331, and the two can rotate around the rotating shaft 333, the locking portion 331 follows the transmitting portion 332 to rotate forward or reversely. Combined with the above description, the locking portion 331 can extend into the engaging groove 211 when rotating forward, thereby locking the adapter assembly 200; conversely, the locking portion 331 can escape from the engaging groove 211 when rotating reversely, that is, release the adapter assembly 200, thereby achieving unlocking between the two.

[0077] It should be noted that the connecting portion 210 may also be configured as a buckle, and the locking portion 331 may be correspondingly configured as a snap-fit ​​groove 211, so that effective snap-fit ​​between the connecting portion 210 and the locking portion 331 can be achieved, thereby achieving connection and disassembly between the adapter assembly 200 and the fixing assembly 300. In addition, the above-mentioned positive rotation is not an absolute clockwise rotation or counterclockwise rotation, but is more for describing the relative movement between the locking portion 331 and the connecting portion 210.

[0078] like Figure 6 and Figure 7 As shown, in some embodiments, the transmission component 320 is disposed on the mounting base 340, and the transmission component 320 may include a first transmission component 321 and a second transmission component 322. The first transmission component 321 is movably connected to the operating component 310, and the first transmission component 321 is configured with a guide portion 3212, and the first transmission component 321 is configured to drive the guide portion 3212 to move along the first direction when the operating component 310 switches between the locking position and the unlocking position; the second transmission component 322 includes a sliding seat 3221, and a guide portion 3223 and a transmission portion 3222 respectively disposed at both ends of the sliding seat 3221, the guide portion 3223 is connected to the transmission portion 332, and the transmission portion 3222 is engaged with the guide portion 3212, and the transmission portion 3222 is configured to drive the sliding seat 3221 to move along the second direction under the guidance of the guide portion 3212.

[0079] The first direction is defined as a vertical direction, and the second direction is defined as a horizontal direction, that is, the first direction and the second direction are perpendicular to each other. Of course, the first direction and the second direction can also be set non-perpendicularly, for example, the angle between the first direction and the second direction is 70°, 80°, etc., which is not limited here.

[0080] The first transmission member 321 can move in the vertical direction when the operating member 310 changes its posture, thereby driving the guide portion 3212 constructed thereon to move in the vertical direction. In order to enable the sliding seat 3221 to move in the horizontal direction and enable the guide portion 3223 at its end to drive the transmission portion 332 to rotate, it is necessary to make the transmission portion 3222 disposed at the end of the sliding seat 3221 engage with the guide portion 3212, and reasonably set the structure of the guide portion 3212, so as to convert the movement of the guide portion 3212 in the vertical direction into the movement of the sliding seat 3221 in the horizontal direction.

[0081] Since the guide part 3223 moves back and forth along the horizontal direction following the sliding seat 3221, in order to drive the transmission part 332 to rotate around the rotating shaft 333 connected thereto, the transmission part 332 can be set to a strip groove style, and the extension direction of the strip groove passes through the center of the rotating shaft 333. The guide part 3223 is designed as a guide rod, which is inserted into the strip groove, and the diameter of the guide rod is adapted to the strip groove, that is, as the guide rod eye moves in the horizontal direction, it can drive the transmission part 332 to rotate, and the design of the strip groove can facilitate the rotation of the transmission part 332.

[0082] Of course, the transmission method between the guide part 3223 and the transmission part 332 can also be, for example Fig.10 and Fig.12 As shown, in some embodiments, the guiding portion 3223 includes a rack fixed to the end of the sliding seat 3221; the transmitting portion 332 includes a gear that can mesh with the rack.

[0083] Specifically, the rack can move along the horizontal direction with the sliding seat 3221, and can drive the gear meshing with it to rotate during the movement. The center of the gear can be set on the rotating shaft 333, and the end away from the rack is connected to the buckle, so that the buckle is indirectly driven to rotate under the drive of the rack, so as to achieve effective engagement or separation between the buckle and the engaging groove 211. In addition, the gear can be provided with a quarter-circle or a third-circle tooth to mesh with the rack.

[0084] The direction of the force can be changed by the guide part 3212 and the transmission part 3222 , and no matter whether the first transmission member 321 moves upward or downward in the vertical direction, it can drive the limit movement, thereby realizing the left and right reciprocating movement of the sliding seat 3221 .

[0085] like Fig.11As shown, in some embodiments, the first transmission member 321 also includes a transmission shaft 3211, and the guide portion 3212 is a guide channel 32121 constructed on the side wall of the transmission shaft 3211; the transmission portion 3222 includes a drive shaft, which is adapted to be inserted into the guide channel 32121, and the extension direction of the guide channel 32121 has an angle with the axial direction of the transmission shaft 3211.

[0086] It can be understood that the guiding direction of the guide channel 32121 is set at an angle, that is, the guide channel 32121 has a point A close to the transmission shaft 3211, and a point B away from the transmission shaft 3211, and the transmission rod 3112 arranged at the end of the sliding seat 3221 is inserted into the guide channel 32121, and the diameter of the transmission rod 3112 is adapted to the guide channel 32121, so that when the transmission shaft 3211 moves in the vertical direction, the transmission rod 3112 in the guide channel 32121 is forced to move toward the axial direction of the transmission shaft 3211 or away from the axial direction of the transmission shaft 3211, thereby achieving the purpose of moving the sliding seat 3221 in the horizontal direction.

[0087] In order to ensure that the sliding seat 3221 moves in the horizontal direction and avoid the deviation caused by the guide channel 32121, in some embodiments, the mounting base 340 is constructed with a limiting slide groove along the second direction, and the sliding seat 3221 is adapted to be embedded in the limiting slide groove.

[0088] Specifically, the setting of the limiting slide groove can limit the sliding seat 3221 in the second direction, and lubrication can be performed between the limiting slide groove and the sliding seat 3221 to reduce the friction force of the sliding seat 3221 sliding relative to the mounting base 340.

[0089] In addition to the above methods, it can also be, Fig.12 As shown, in one example, along the second direction, the side wall of the sliding seat 3221 is structured with a limiting guide groove 3224, and a guide column is provided in the mounting base 340, and the guide column is adapted to be plugged into the limiting guide groove 3224. Specifically, the plug-in cooperation between the limiting guide groove 3224 and the guide column can limit the sliding seat 3221 in the horizontal direction, and can effectively prevent the sliding seat 3221 from rotating. Of course, the limiting method of this example can be set together with the limiting method of the above example, or used alone, and is not limited here.

[0090] The above-mentioned guide channel 32121 can also be set to an arc shape, and the specific shape is not limited here. When the operating part 310 is in the locking position, that is, the transmission shaft 3211 moves down to the extreme position, and the transmission rod 3112 moves relatively to the highest point of the guide channel 32121, in order to avoid or reduce the possibility that the transmission rod 3112 is still offset relative to the guide channel 32121, in some embodiments, the guide channel 32121 includes an abutment surface parallel to the axial direction of the transmission shaft 3211, and when the operating part 310 is in the locking position, the drive shaft is pressed against the abutment surface.

[0091] It can be understood that a contact surface is provided at point B of the guide channel 32121, and the contact surface may be an arc surface or a plane. The contact surface is provided to stabilize the transmission rod 3112 at the point B, thereby ensuring the stability of the sliding seat 3221, and further ensuring the stability of the locking portion 331 locking the connecting portion 210.

[0092] In order to achieve unlocking between the locking component and the connecting part 210 with one action of the operating component 310, in some embodiments, a strip guide groove 32111 is constructed at the end of the transmission shaft 3211; the operating component 310 includes an operating handle 311, and the operating handle 311 is arranged on the mounting base 340 through the connecting shaft 3111, and a transmission rod 3112 is arranged at one end of the operating handle 311, and a handle 3113 is arranged at the other end, and the transmission rod 3112 is inserted into the strip guide groove 32111.

[0093] Specifically, the extension direction of the strip guide groove 32111 is the second direction. The handle 3113 of the operating handle 311 is buckled into the mounting base 340 when in the locked position, and the transmission rod 3112 at the end of the operating handle 311 is inserted into the strip guide groove 32111. When unlocking is required, the handle is turned outward, and one end of the operating handle 311 having the transmission rod 3112 rotates along with it, and the transmission rod 3112 will apply force to the transmission shaft 3211, so that the transmission shaft 3211 moves in the vertical direction, and the guide channel 32121 on the transmission shaft 3211 forces the transmission rod 3112 to move in the direction close to the transmission shaft 3211, that is, the sliding seat 3221 drives the rack thereon to move in the direction close to the transmission shaft 3211, and the rack drives the gear to rotate in the opposite direction, thereby causing the buckle to disengage from the clamping groove 211, and finally realizing the rapid disassembly of the fixing assembly 300 and the adapter assembly 200. The locking process is opposite to the unlocking process described above, and the handle is pushed inward to snap into place on the mounting base 340. The specific transmission process can be understood by referring to the above example, and will not be described in detail here.

[0094] It should be noted that a guide structure can be constructed on one side of the transmission shaft 3211, that is, a second transmission member 322 and a locking member are set on a single side of the transmission shaft 3211. This arrangement can achieve the locking and release of the connecting part 210, but due to poor stability, based on this problem, in some embodiments, guide channels 32121 with the same structure are respectively constructed on both sides of the transmission shaft 3211, and the two guide channels 32121 are respectively connected to two groups of second transmission members 322, and the two groups of second transmission members 322 are respectively connected to two groups of locking members 330, so that the two symmetrical groups of locking members 330 can lock the connecting part 210 at the same time.

[0095] Specifically, Figure 7 and Fig. 9 As shown, guide channels 32121 with the same structure are respectively arranged on the symmetrical sides of the transmission shaft 3211, and two groups of first transmission members 321 and locking members 330 respectively connected to the guide channels 32121 are arranged. By driving the operating handle 311 once, the symmetrically arranged second transmission members 322 and locking members 330 can be effectively transmitted, so that the two relative buckles can be rotated towards / away from each other to jointly realize the locking or release of the connecting part 210, and the connection firmness can be guaranteed when locked.

[0096] In order to ensure the stability of the transmission shaft 3211 moving in the vertical direction, a limiting cavity adapted to the transmission shaft 3211 can be constructed in the mounting base 340. In addition, in order to ensure that the operating handle 311 is not easy to fall out in the locked position, Fig. 9 and Fig.11 As shown, in some embodiments, the first transmission member 321 also includes a second elastic member 3213, one end of the second elastic member 3213 is limited to the end of the transmission shaft 3211 away from the strip guide groove 32111, and the other end is limited to the mounting base 340, and the second elastic member 3213 is configured so that when the operating member 310 is in the locked position, the second elastic member 3213 is pressed against the transmission shaft 3211.

[0097] Specifically, the second elastic member 3213, i.e., a spring, is arranged between the transmission shaft 3211 and the mounting base 340. When the operating handle 311 is in the locked position, the second elastic member 3213 is in a compressed force storage state, and can provide continuous pressure to the transmission shaft 3211, so that the strip guide groove at its end continuously presses against the transmission rod 3112 inserted therein, thereby making the handle at the other end of the transmission rod 3112 continuously located in the mounting base 340, thereby avoiding the situation where the handle at the other end of the transmission rod 3112 is easily detached from the mounting base 340 due to insufficient pressing force on the transmission rod 3112 when the second elastic member 3213 is in its original length state or stretched state.

[0098] In addition, in order to further limit the movement of the transmission shaft 3211 in the vertical direction, a groove can be provided at the end of the transmission shaft 3211 away from the strip guide groove 32111, so that one end of the second elastic member 3213 is limited to the bottom of the groove, and the other end is limited to the mounting base 340. This arrangement can not only ensure that the operating handle 311 is in a locked position and is not easy to fall out of the mounting base 340, but also limit the movement of the transmission shaft 3211.

[0099] When the operating component 310 is in the unlocked position, the buckle is disengaged from the locking groove 211 of the adapter assembly 200 and is in an open state. If the fixing assembly 300 needs to be locked on the adapter at this time, it is necessary to manually press the fixing assembly 300 on the adapter assembly 200 and at the same time bend the operating handle 311 to perform the locking operation, which is not convenient to implement with one hand. To solve this problem, in some embodiments, the locking component 330 also includes a first elastic member 334, one end of the first elastic member 334 is limited to the buckle, and the other end is limited to the mounting base 340. The first elastic member 334 is configured so that when the operating component 310 is in the unlocked position, the first elastic member 334 forces the buckle to rotate forward.

[0100] It is understandable that a first elastic member 334, i.e., a compression spring, is provided between the buckle and the mounting base 340. When the operating handle 311 is in the unlocked position, the first elastic member 334 can still exert force on the buckle, so that the buckle rotates forward and reaches a position where it extends into the snap-in groove 211. When the fixed assembly 300 is close to the adapter assembly 200, the annular block formed with the snap-in groove 211 will first abut against the buckle. Under the continuous push of the external force, the annular block will compress the first elastic member 334, so that the buckle rotates to allow the annular block to enter the fixed assembly 300. As the annular block continues to enter, the buckle will slide into the snap-in groove 211. This method can also realize the connection between the fixed assembly 300 and the adapter, but the connection is not firm. It can be used as a fixed assembly 300 pre-connected to the adapter assembly 200. A more stable connection method also requires the operating handle 311 to be bent to the locked position. The specific understanding can be referred to the above example, and it will not be repeated here.

[0101] like Figure 7 As shown, in some embodiments, the body 220 is configured with a positioning groove 221 , and the mounting base 340 is configured with a positioning rod 341 , and the positioning rod 341 is adapted to be plugged into the positioning groove 221 .

[0102] It can be understood that the exposed surface of the main body 220 is constructed with a positioning groove 221, and a positioning rod 341 is also provided on the side of the mounting base 340 facing the main body 220. The design of the positioning groove 221 and the positioning rod 341 can realize the fast and accurate docking of the fixing component 300 and the adapter component 200.

[0103] Of course, the arrangement of the positioning groove 221 and the positioning member is not limited to the above-mentioned example. The positioning groove 221 can also be formed on the mounting base 340, and the positioning rod 341 can be arranged on the body 220. No specific limitation is made here.

[0104] In addition, the mounting base 340 may also have a shell, in which the operating component 310, the transmission component 320 and the locking component 330 are arranged. The shell has a makeshift channel, and the makeshift channel is used for the connecting part 210 of the adapter assembly 200 to enter, and the buckle of the locking component 330 extends into the makeshift channel to trigger the buckle after the connecting part 210 enters the makeshift channel, so that the buckle and the first elastic member 334 form a first lock on the connecting part 210, and finally the operating component 310 is operated to achieve a second lock on the connecting part 210.

[0105] Finally, it should be noted that the above implementation modes are only used to illustrate the present application, rather than to limit the present application. Although the present application is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should be included in the scope of the claims of the present application.
