[0015] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects: 1. The present application provides a positioning surface and an installation hole on the ceiling crossbeam, wherein the swivel seat is provided with a main body and a connecting portion, and a first clamping structure and a second clamping structure that cooperate with each other are respectively provided on the swivel seat and the ceiling crossbeam during installation. At this time, the swivel seat is restricted from moving relative to the ceiling crossbeam along a first direction. During the process of the connecting portion moving to the first reference surface and the positioning surface being in abutment, the first clamping structure and the second clamping structure enter a mating state. When the first reference surface is in abutment with the positioning surface, the first clamping structure and the second clamping structure cooperate to restrict the swivel seat from moving relative to the ceiling crossbeam along a second direction parallel to the positioning surface and a third direction perpendicular to the positioning surface. The second direction is perpendicular to the first direction. When designing the entire vehicle, the first direction is designed as the width direction of the vehicle body, the second direction is the length direction of the vehicle body, and the third direction is the height direction of the vehicle body, thereby restricting the movement of the swivel seat along the width, length and height directions of the vehicle body, and realizing the clamping installation of the swivel seat on the ceiling crossbeam. The first clamping structure and the second clamping structure automatically enter a mating state during the installation of the rotating shaft seat, without the need for additional steps, thereby reducing the number of steps and lowering the manufacturing cost of the entire vehicle.

[0016] 2. The present application provides an elastic clip, and after the shaft seat is installed on the ceiling beam, the elastic clip passes through the locking hole of the main body and the mounting hole of the ceiling beam, so that the main body and the ceiling beam are located between the first limiting piece and the second limiting piece of each spring piece in the third direction, and the main body and the ceiling beam are respectively abutted against the second limiting piece and the first limiting piece, and under the action of their own elastic force, the two spring pieces are respectively abutted against the inner walls on the opposite sides of the locking hole in a direction parallel to the first reference plane, so that the first limiting piece and the second limiting piece of each spring piece cooperate to limit the relative movement of the main body and the ceiling beam, thereby fixing the shaft seat on the ceiling beam, and the elastic clip's own elastic force keeps it in a state of fixing the shaft seat and the ceiling beam.

[0017] 3. The present application provides barbs on the spring pieces of the elastic clip, which are connected to the connecting part and extend to the side of the first limiting piece away from the other spring piece. After the elastic clip is installed, when the rotating shaft seat is subjected to a force away from the ceiling crossbeam, the two spring pieces of the elastic clip move closer to each other due to the force, and the elastic clip as a whole moves relative to the ceiling crossbeam along the third direction. Due to the V-shaped structure of the two connecting sections, when the two spring pieces move closer to each other and the elastic clip as a whole moves relative to the ceiling crossbeam along the third direction, the barbs will abut against the ceiling crossbeam when the first limiting piece is not completely separated from the ceiling crossbeam, and the two barbs are respectively abutted against the two sides of the ceiling crossbeam mounting hole in an eight-shaped shape. The elastic clip is hindered by the two barbs and cannot continue to move relative to the ceiling crossbeam. Even if the elastic clip is subjected to a large force and the two barbs are bent and deformed to both sides, the two barbs always remain in a state of abutting against the ceiling crossbeam and limit the elastic clip from separating from the ceiling crossbeam, thereby improving the installation stability of the rotating shaft seat and avoiding falling off in extreme cases.

[0025] Reference Figure 1-11 As shown, the embodiment of the present application provides a car sun visor shaft seat fixing structure, including a roof beam 1 and a shaft seat 2, the roof beam 1 has a positioning surface 11, the positioning surface 11 is provided with a mounting hole 12 that passes through the roof beam 1, the shaft seat 2 includes a main body 21 and a connecting portion 22, the main body 21 is provided with a first reference surface 211, the connecting portion 22 can pass through the mounting hole 12 and can be moved to the first reference surface 211 and fit with the positioning surface 11, and when the connecting portion 22 passes through the mounting hole 12, it is restricted from moving relative to the roof beam 1 in a first direction parallel to the positioning surface 11. A first clamping structure is provided on the rotating shaft seat 2, and a second clamping structure is provided on the ceiling beam 1, which is suitable for the first clamping structure and the second clamping structure to enter a mating state when the connecting portion 22 passes through the mounting hole 12 and moves to the first reference surface 211 and fits the positioning surface 11. When the first reference surface 211 fits the positioning surface 11, the first clamping structure and the second clamping structure cooperate to limit the rotating shaft seat 2 from moving relative to the ceiling beam 1 in a second direction parallel to the positioning surface 11 and a third direction perpendicular to the positioning surface 11, and the second direction is perpendicular to the first direction.

[0026] Reference Figure 1-2 As shown, the first reference surface 211 is arranged on one side of the main body 21 close to the connecting portion 22, and the connecting portion 22 extends in a direction perpendicular to the first reference surface 211, so that the connecting portion 22 can move to the first reference surface 211 and the positioning surface 11 after passing through the mounting hole 12.

[0027] Reference Figure 1-2 and Figure 3As shown, the first clamping structure includes a limiting portion 23 connected to the connecting portion 22. The limiting portion 23 and the connecting portion 22 are spaced apart in a fourth direction parallel to the first reference surface 211. The limiting portion 23 can pass through the mounting hole 12 along the connecting portion 22. When the connecting portion 22 passes through the mounting hole 12 and moves until the first reference surface 211 is aligned with the positioning surface 11, the fourth direction is parallel to the second direction. In the third direction, the limiting portion 23 and the first reference surface 211 respectively abut against both sides of the ceiling beam 1 to limit the movement of the rotating shaft seat 2 relative to the ceiling beam 1 along the third direction. Specifically, the limiting portion 23 is connected to an end of the connecting portion 22 away from the main body 21 and extends toward the main body 21 in a direction perpendicular to the first reference surface 211, so that when the first reference surface 211 is aligned with the positioning surface 11, the limiting portion 23 abuts against the ceiling beam 1 on the other side of the ceiling beam 1. During installation, first pass the limiting portion 23 through the mounting hole 12, then rotate the shaft seat 2 to allow the connecting portion 22 to pass through the mounting hole 12 until the limiting portion 23 and the first reference surface 211 respectively abut against both sides of the ceiling beam 1. At this time, the shaft seat 2 is restricted from moving relative to the ceiling beam 1 along the third direction and can only be detached from the ceiling beam 1 by rotating in the opposite direction to that during installation.

[0028] Reference Figure 1-4 As shown, in order to restrict the connection portion 22 from moving along the first direction after passing through the mounting hole 12, the connection portion 22 is set to have a width in a sixth direction parallel to the first reference surface 211 that is slightly smaller than the width of the mounting hole 12 in the first direction, and the sixth direction is perpendicular to the fourth direction. During installation, the connection portion 22 passes through the mounting hole 12 with the sixth direction and the first direction parallel to each other; wedge-shaped ridges 24 extending in a direction perpendicular to the first reference surface 211 are provided on both sides of the connection portion 22 in the sixth direction, and the thickness of the wedge-shaped ridges 24 in the sixth direction gradually decreases as it moves away from the main body 21, and the maximum thickness of the wedge-shaped ridges 24 can fill the gap between the connection portion 22 and the inner wall of the mounting hole 12 in the sixth direction when the connection portion 22 passes through the mounting hole 12. When the connection portion 22 passes through the mounting hole 12 and moves until the first reference surface 211 and the positioning surface 11 are aligned, the wedge-shaped ridges 24 on both sides of the connection portion 22 respectively abut against the inner walls on both sides of the mounting hole 12 to restrict the connection portion 22 from moving relative to the ceiling beam 1 along the first direction.

[0029] Reference Figure 1-5As shown, further, the first clamping structure also includes a first clamping block 25 connected to the limiting portion 23 and a second clamping block 26 connected to the main body 21, the first clamping block 25 and the second clamping block 26 are distributed along the fourth direction and are located on both sides of the connecting portion 22 in the fourth direction, the second clamping structure includes a clamping hole 13 provided on the ceiling beam 1, when the connecting portion 22 passes through the mounting hole 12 and moves to the first reference surface 211 to fit with the positioning surface 11, the first clamping block 25 and the second clamping block 26 are respectively inserted into the clamping hole 13 and the mounting hole 12, and in the second direction, the first clamping block 25 and the side wall of the clamping hole 13 away from the mounting hole 12 are abutted, and the second clamping block 26 and the side wall of the mounting hole 12 away from the clamping hole 13 are abutted.

[0030] Reference Figure 3-4 As shown, specifically, the first clamping block 25 is arranged at one end of the connecting portion 22 close to the main body 21 in a direction perpendicular to the first reference plane 211, the second clamping block 26 is connected to the first reference plane 211 of the main body 21, and the clamping holes 13 and the mounting holes 12 on the ceiling beam 1 are spaced apart along the second direction. The first clamping block 25 is then moved back into engagement with the mounting hole 12 so that the first clamping block 25 and the second clamping block 26 can be moved back into engagement with the mounting hole 12. At this time, the shaft seat 2 is restricted from moving relative to the ceiling crossbeam 1 along the first direction, the second direction, and the third direction. If the shaft seat 2 is to be removed from the ceiling crossbeam 1, the main body 21 needs to be moved away from the ceiling crossbeam 1 in the fourth direction, away from the side of the limiting portion 23, so as to first disengage the second clamping block 26 from the mounting hole 12. At this time, the elastic force of the limiting portion 23 needs to be overcome. Therefore, the shaft seat 2 can maintain the first reference surface 211 and the positioning surface 11 in a state of being in contact and abutting each other and fixed on the ceiling crossbeam 1, thereby achieving the fixed installation of the shaft seat 2 on the ceiling crossbeam 1. In the process, each clamping structure automatically enters a mating state, without the need for additional steps, thereby reducing the manufacturing cost of the entire vehicle. In this embodiment, the side surface of the ceiling crossbeam 1 opposite to the positioning surface 11 is a plane parallel to the positioning surface 11, and a protrusion protruding from the plane is provided on the side of the clamping hole 13 on the ceiling crossbeam 1 away from the mounting hole 12, and the limiting portion 23 abuts against the protrusion.

[0031] Specifically, the entire rotating shaft seat 2 is made of plastic material and is integrally formed by injection molding, so that it has sufficient structural strength and can undergo a certain elastic deformation according to the design.

[0032] Furthermore, in order to prevent the rotating shaft seat 2 from being separated from the ceiling beam 1 due to a large external force, a locking assembly is also provided. The locking assembly is used to connect the main body 21 and the ceiling beam 1 when the connecting part 22 passes through the mounting hole 12 and moves to the first reference surface 211 to fit with the positioning surface 11.

[0033] Reference Figure 1-2 and Figure 7-8 As shown, specifically, the locking assembly includes an elastic clip 3, which includes two springs 31 connected to each other at one end. The springs 31 include a connecting section 311 and a fixing section 312. The connecting sections 311 of the two springs 31 are connected to each other at one end and are V-shaped in the undeformed state. The fixing section 312 is connected to the other end of the connecting section 311 and is located on the side where the two connecting sections 311 are close to each other. One end of the fixing section 312 is bent away from the other spring 31 to form a first limiting piece 3121 and connected to the connecting section 311. The other end of the fixing section 312 is bent away from the other spring 31 to form a second limiting piece 3122. A locking hole 212 for the elastic clip 3 to pass through is formed in the main body 21. The locking hole 212 is through in a direction perpendicular to the first reference surface 211. When the connecting portion 22 passes through the mounting hole 12 and moves until the first reference surface 211 is aligned with the positioning surface 11, the locking hole 212 is connected to the mounting hole 12. Among them, the elastic clip 3 is used to pass through the locking hole 212 and the mounting hole 12 when the connecting part 22 passes through the mounting hole 12 and moves to the first reference surface 211 to fit the positioning surface 11, so that the main body 21 and the ceiling beam 1 are located between the first limiting piece 3121 and the second limiting piece 3122 of each spring piece 31 in the third direction, and the main body 21 and the ceiling beam 1 are respectively abutted against the second limiting piece 3122 and the first limiting piece 3121, and under the action of their own elastic force, the two spring pieces 31 are respectively abutted against the inner walls on the opposite sides of the locking hole 212 in a direction parallel to the first reference surface 211.

[0034] Reference Figure 1-2 and Figure 8As shown, specifically, when the elastic clip 3 is in its undeformed state, the portion of the fixing section 312 between the first limiting piece 3121 and the second limiting piece 3122 is parallel to the planes of symmetry of the two connecting portions 22. The angle between the first limiting piece 3121 and the portion of the fixing section 312 between the first limiting piece 3121 and the second limiting piece 3122 is obtuse, and the angle between the second limiting piece 3122 and the portion is perpendicular. The side of the mounting hole 12 farther from the engaging hole 13 in the second direction is narrower in the first direction. When the first reference surface 211 is aligned with the positioning surface 11, the locking hole 212 is in communication with this portion of the mounting hole 12, and the elastic clip 3 passes through the locking hole 212 and this portion of the mounting hole 12. During installation, after the shaft seat 2 is installed on the ceiling beam 1 until the first reference surface 211 is aligned with the positioning surface 11, the elastic clip 3 is moved from the main body 21 of the shaft seat 2 away from the ceiling beam 1 along the third direction to insert into the locking hole 212 and the installation hole 12. During the insertion process, the two connecting sections 311 respectively abut against the inner walls on both sides of the locking hole 212, and due to the V-shaped structure of the connecting section 311, the two spring pieces 31 are squeezed and moved closer to each other until the maximum distance between the two first limiting pieces 3121 is less than the width of the locking hole 212 in the second direction. Thus, the elastic clip 3 can pass through the locking hole 212 and the mounting hole 12. After being inserted into place, the elastic clip 3 recovers its deformation, causing the two spring pieces 31 to move away from each other until the maximum distance between the two first limiting pieces 3121 is greater than the width of the locking hole 212 and the mounting hole 12 in the second direction. This causes the main body 21 and the ceiling beam 1 to be located between the second limiting piece 3122 and the first limiting piece 3121 of each spring piece 31 in the third direction, and the two spring pieces 31 abut against the inner walls of the locking hole 212 on opposite sides in a direction parallel to the first reference plane 211. At this time, under the restraint of the second limiting piece 3122 and the first limiting piece 3121 of each spring piece 31, the main body 21 and the ceiling beam 1 cannot move relative to each other, and the side of the main body 21 away from the limiting portion 23 in the fourth direction cannot move away from the ceiling beam 1, thereby preventing the rotating shaft seat 2 from detaching from the ceiling beam 1.

[0035] Reference Figure 1-2 and Figure 7-8As shown, further, a barb 313 is provided at one end where the connecting section 311 is connected to the fixing section 312. One end of the barb 313 is connected to the connecting section 311, and the other end extends away from the connecting section 311 along the length direction of the connecting section 311 to a side of the first limiting piece 3121 away from the other elastic piece 31. Specifically, the maximum distance between the two barbs 313 is smaller than the maximum distance between the two first limiting pieces 3121. Therefore, when the elastic buckle 3 passes through the locking hole 212 and the mounting hole 12, the two elastic pieces 31 need to approach each other until the maximum distance between the two barbs 313 is smaller than the width of the locking hole 212 and the width of the mounting hole 12. When the lever 3 is in the unlocked position, the two levers 31 are in the unlocked position, and the two levers 31 are in the unlocked position, so that the lever 3 is unlocked and the two levers 31 are unlocked.

[0036] Reference Figure 3-4 When the cam 314 is in the unlocking state, the locking cam 312 is in the unlocking state, and the locking cam 312 is in the unlocking state, so that the cam 314 can be unlocked when the cam 314 is unlocked.

[0037] When installing the shaft seat 2, the elastic buckle 3 can be pre-installed on the shaft seat 2. Specifically, the elastic buckle 3 is passed through the locking hole 212 and moved until the third limiting piece 314 is aligned with the slot 213. Then the elastic buckle 3 recovers its deformation until the third limiting piece 314 is inserted into the slot 213. At this time, the second limiting piece 3122 and the main body 21 are in contact with the side away from the first reference surface 211, and the two springs 31 are respectively in contact with the inner walls of the locking hole 212 on both sides. Under the cooperation of the third limiting piece 314 and the second limiting piece 3122, the elastic buckle 3 is restricted from being separated from the main body 21. Figure 10 As shown, after the elastic clip 3 is installed on the main body 21, the shaft seat 2 is installed on the ceiling beam 1. During the installation process, the elastic clip 3 moves with the shaft seat 2 and is inserted into the installation hole 12. After the shaft seat 2 is installed in place, the elastic clip 3 automatically forms a mating connection with the ceiling beam 1 under its own elastic force, thereby realizing the fixed installation of the shaft seat 2 on the ceiling beam 1.

[0038] In this embodiment, two structural grooves along the length direction are provided on the spring piece 31, and the structural grooves extend from the connecting section 311 to the fixed section 312. The part between the two structural grooves is cut off from the middle, and the part close to the fixed section 312 is bent in the direction in which the two spring pieces 31 are away from each other to form a third limiting piece 314, and the part close to the connecting section 311 extends along the length direction of the connecting end to form a barb 313.

[0039] Reference Figure 1-2 and Figure 8-9 As shown, further, in order to prevent the elastic clip 3 from loosening, the locking assembly also includes a locking member 4, which is used to be connected to the main body 21 when the elastic clip 3 is connected to the main body 21 and the ceiling beam 1, so as to limit the two spring pieces 31 of the elastic clip 3 from moving closer to each other.

[0040] Reference Figure 8-9As shown, specifically, the locking member 4 includes a blocking block 41 , which is used to be inserted into the locking hole 212 and positioned between the two elastic sheets 31 and abut against the two elastic sheets 31 when the elastic buckle 3 connects the main body 21 and the ceiling beam 1 . The locking member 4 also includes a blocking cover 42, which is provided with a second reference surface 421. The blocking block 41 is connected to the second reference surface 421 of the blocking cover 42. The blocking block 41 is provided with a first clamping protrusion 43 on both sides of the fifth direction parallel to the second reference surface 421. One of the first clamping protrusions 43 is connected to the blocking block 41 through an elastic limiting plate 44. The elastic limiting plate 44 can be elastically deformed so that the spacing between the two first clamping protrusions 43 in the fifth direction is variable. Locking grooves 214 are respectively provided on the inner walls of the opposite sides of the locking hole 212. The locking member 4 is suitable for moving from the main body 21 away from the side of the ceiling beam 1, and moving along the third direction with the second reference surface 421 and the first reference surface 211 parallel to the first reference surface 211 to insert the blocking block 41 into the locking hole 212. When moving to the second reference surface 421 to abut against the main body 21, the two first clamping protrusions 43 are respectively embedded in the two locking grooves 214 to fix the locking member 4 to the main body 21.

[0041] Reference Figure 4 and Figure 9 As shown, the locking grooves 214 are provided on the inner walls on both sides of the locking hole 212 in the second direction, and the first engaging protrusions 43 are provided in a wedge shape. When the first engaging protrusion 43 is inserted into the locking hole 212 along with the blocking block 41, the elastic limiting plate 44 is driven by the inner wall of the locking hole 212 to undergo elastic deformation so as to be smoothly inserted into the locking hole 212. When the blocking block 41 is inserted into the second reference surface 421 and abuts against the main body 21, the elastic limiting plate 44 recovers its deformation so that the first engaging protrusion 43 is embedded in the locking groove 214. At this time, the locking member 4 is restricted from moving relative to the main body 21 along the third direction by the engaging fit between the first engaging protrusion 43 and the locking groove 214 and the abutting fit between the blocking cover 42 and the main body 21, that is, the locking member 4 is fixed to the main body 21, so that the elastic buckle 3 remains connected to the main body 21 and the ceiling beam 1 through the locking member 4, thereby keeping the rotating shaft seat 2 connected to the ceiling beam 1, and preventing the rotating shaft seat 2 from being separated from the ceiling beam 1 due to factors such as vibration.

[0042] Reference Figure 8-9As shown, further, two elastic cards 45 are connected to the block 41 and are arranged at intervals along the fifth direction. The first snap-fitting protrusion 43 and the elastic card 45 are distributed in sequence in a direction perpendicular to the second reference surface 421 and away from the blocking cover 42. The two elastic cards 45 are respectively provided with a second snap-fitting protrusion 46 on the side away from each other. The elastic card 45 can be elastically deformed so that the spacing between the two second snap-fitting protrusions 46 in the fifth direction is variable. When the block 41 is inserted into the locking hole 212, it can be moved until the two second snap-fitting protrusions 46 are respectively embedded in the two locking grooves 214, and when the second snap-fitting protrusions 46 are respectively embedded in the two locking grooves 214, the block 41 is restricted from moving in a direction perpendicular to the first reference surface 211 to separate from the main body 21.

[0043] Reference Figure 9 As shown, specifically, the second clamping protrusion 46 is also wedge-shaped so as to be inserted into the locking hole 212. Before the rotating shaft seat 2 is installed on the ceiling beam 1, the elastic clip 3 is pre-installed on the main body 21, and the locking member 4 can also be pre-installed on the main body 21. Specifically, two elastic cards 45 and the second clamping protrusion 46 are inserted into the locking hole 212. The two elastic cards 45 are squeezed by the inner wall of the locking hole 212 and deformed close to each other so that the distance between the two second clamping protrusions 46 is smaller than the width of the locking hole 212. The two elastic cards 45 and the second clamping protrusion 46 are inserted into the locking hole 212. After the second clamping protrusion 46 and the locking groove 214 are aligned, the elastic card 45 recovers the deformation so that the second clamping protrusion 46 is embedded in the locking groove 214, thereby limiting the locking member 4 from being separated from the main body 21 under the limit of the second clamping protrusion 46. Figure 10 As shown, the elastic buckle 3 and the locking member 4 are both pre-installed on the main body 21. After the shaft seat 2 is installed in place on the ceiling beam 1 and the elastic buckle 3 is installed in place, the locking member 4 is pressed into the locking hole 212 until the first engaging protrusion 43 is embedded in the locking groove 214. The locking member 4 is installed in place, completing the installation of the shaft seat 2. The shaft seat 2, the elastic buckle 3, and the locking member 4 can be pre-assembled together as a product at the factory. During installation, only one assembly process is required to complete the assembly of the shaft seat 2 on the ceiling beam 1, further improving efficiency and reducing costs.

[0044] In actual design, the first direction is defined as the vehicle body width, the second direction as the vehicle body length, and the third direction as the vehicle body height. The main body 21 of the pivot seat 2 is positioned below the roof crossbeam 1, meaning that the pivot seat 2 is mounted upward from below the roof crossbeam 1. In this embodiment, the pivot seat 2 is provided with a pivot hole, the axis of which is perpendicular to the first reference plane 211. The pivot hole extends through both ends and passes through the main body 21 and the connecting portion 22. During installation, the pivot shaft is passed through the pivot hole and mounted on the pivot seat 2. Furthermore, as shown in the figures, the stopper 23 is configured as a hollow structure, thereby forming a receiving cavity 231 within the stopper 23. This cavity 231 accommodates the sun visor light connection interface 5, which is used to connect to the vehicle body power supply. The connection interface 5 is connected to a control wiring harness, which passes through the hollow pivot shaft, then passes through the roof crossbeam 1 and the pivot seat 2, extending into the vehicle body and connecting to the sun visor light.

[0045] Reference Figure 11As shown, in order to realize the fixed installation of the connection interface 5 on the rotating shaft seat 2, the accommodating cavity 231 is penetrated at both ends in the fourth direction, and is penetrated in the direction perpendicular to the first reference surface 211 away from the side of the main body 21, so that the two side walls of the accommodating cavity 231 in the sixth direction can be elastically deformed in the sixth direction, and wedge-shaped blocks 27 are respectively provided on the inner walls of the two sides of the accommodating cavity 231 in the sixth direction, and corresponding fixing strips 51 that cooperate with the wedge-shaped blocks 27 are provided on the opposite side walls of the connection interface 5. When the connection interface 5 is installed, it is along the first reference surface 211. The first reference surface 211 is moved and assembled into the accommodating cavity 231, and during the assembly process, the fixing strip 51 and the wedge-shaped block 27 cooperate to make the two side walls of the accommodating cavity 231 in the sixth direction move away from each other, so that the fixing strip 51 can pass over the wedge-shaped block 27, and after the fixing strip 51 passes over the wedge-shaped block 27, the connecting interface 5 is abutted against the bottom wall of the accommodating cavity 231 and the two side walls of the accommodating cavity 231 in the sixth direction are reset, so that the wedge-shaped block 27 cooperates to limit the connecting interface 5 from moving away from the main body 21 in the direction perpendicular to the first reference surface 211. At the same time, limit bars 28 are respectively provided on the inner walls of the accommodating cavity 231 on both sides in the sixth direction. The limit bars 28 extend in a direction perpendicular to the first reference surface 211. When the connection interface 5 is inserted into the accommodating cavity 231, the two sides of the fixed bar 51 abut against the two limit bars 28 to limit the movement of the connection interface 5 relative to the rotating shaft seat 2 along the sixth direction. The two limit bars 28 are spaced apart in the fourth direction. When the connection interface 5 is inserted into the accommodating cavity 231, the two fixed bars 51 are located on the side where the two limit bars 28 are close to each other in the fourth direction, and the two fixed bars 51 abut against the two limit bars 28 in a one-to-one correspondence in the fourth direction. The limit bars 28 and the fixed bars 51 cooperate to limit the movement of the connection interface 5 relative to the rotating shaft seat 2 along the fourth direction, thereby achieving the clamping fixation of the connection interface 5 on the rotating shaft seat 2. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
