Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles or simulated racing cars, in particular to a device for quickly assembling and disassembling a steering wheel for a vehicle or simulated racing car. Background Art

[0002] In existing racing and simulated racing systems, the role of quick release cannot be ignored. In racing and simulated racing, the steering wheel is a device that needs to be frequently disassembled and replaced, so a device is needed to allow the steering wheel to be quickly removed and installed. This device is the quick release. It is usually divided into two parts, one part is installed at the front end of the steering rod of a real car or the front end of the base of the simulated racing system, and the other part is installed at the back of the steering wheel. The two parts can be docked to allow the steering wheel to be installed on the base of the racing car or simulated racing car. However, in the existing technology, the docking installation and disassembly of the two parts require multiple manual operations, and the installation is not convenient and quick. On the other hand, the two parts are not stable after installation and there are problems such as shaking. Utility Model Content

[0003] In response to the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a quick installation and removal device for a steering wheel of a vehicle or simulated racing car, which occupies a small space. After the steering wheel connecting portion and the base connecting portion are connected, the rotation is transmitted through the engagement of the steel ball and the first and second docking teeth. The first and second docking teeth are in staggered contact and tightly fit, and the connection between the two is stable and not easy to shake after the connection, so that the steel ball and the second connecting seat have a tendency to be relatively pressed, further reducing the sliding and shaking after the steering wheel is installed. Through the cooperation of the second elastic member and the inner ring, the inner ring blocks one end of the steel ball hole on the first connecting seat, so that the steel ball blocks the reset of the pull ring. Therefore, when installing the steering wheel, there is no need to manually pull the pull ring or other components. It is only necessary to align the steering wheel connecting portion with the base connecting portion and insert it to lock the steel ball. The installation is convenient, fast and labor-saving.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A device for quickly installing and removing a steering wheel for a vehicle or a simulated racing car comprises a steering wheel connecting portion and a base connecting portion, wherein one end of the steering wheel connecting portion is connected to the steering wheel and the other end is detachably connected to the base connecting portion, one end of the base connecting portion is connected to the vehicle or the simulated racing car and the other end is detachably connected to the steering wheel connecting portion, the steering wheel connecting portion comprises a first connecting seat, a pull ring and an inner ring, the first connecting seat is cylindrical, a plurality of through-hole steel ball holes are provided on the side wall of the first connecting seat, the plurality of steel ball holes are evenly spaced along the circumference of the first connecting seat, and each steel ball hole is evenly spaced. A steel ball is placed inside, the pull ring is movably sleeved on the outside of the first connecting seat, and the inner ring is movably arranged inside the first connecting seat. The pull ring and the inner ring limit or release the limit of the steel ball from the inside and outside of the first connecting seat respectively through their respective movements. One end of the base connecting part can be inserted into the first connecting seat to push open the inner ring. Under the limitation of the pull ring, a part of the steel ball is stuck in the base connecting part and the other part remains in the steel ball hole, thereby realizing the relative fixation of the base connecting part and the steering wheel connecting part. The limitation of the steel ball is released by moving the pull ring, and one end of the base connecting part can be pulled out from the first connecting seat.

[0006] As a further improvement of the above technical solution:

[0007] The steering wheel connection part also includes a second elastic member for resetting the inner ring. One end of the second elastic member is fixed relative to the first connecting seat, and the other end contacts one end surface of the inner ring. When the second elastic member is in a natural state and is not subject to external force, the inner ring blocks one end of the steel ball hole on the inner surface of the first connecting seat.

[0008] The steering wheel connection part also includes a steering wheel connection piece and a first elastic piece for resetting the pull ring. One end of the first connecting seat is connected to the steering wheel connection piece, which is used to connect to the steering wheel. The first elastic piece is located between the steering wheel connection piece and the pull ring.

[0009] The pull ring includes a steel ball matching part, one end of the steel ball matching part is a locking part, and the other end is a steel ball groove part. The inner diameter of the locking part is not less than the outer diameter of the first connecting seat. The inner surface of the steel ball groove part is provided with an annular groove. The groove is circumferentially arranged along the inner surface of the pull ring. The groove can be used for steel balls to be inserted. The inner diameter of the steel ball groove part is larger than the inner diameter of the locking part. When the first elastic part is in a natural state and is not subject to external force, the locking part faces and contacts the steel ball.

[0010] The steering wheel connection part also includes a plurality of first docking teeth, one end of the first docking teeth is fixedly connected to the end face of the first connecting seat away from one end of the steering wheel connecting member, and the other end is cantilevered in a direction away from the first connecting seat. The plurality of first docking teeth are arranged at intervals along the circumference of the first connecting seat, and the base connection part includes a plurality of second docking teeth. After the steering wheel connection part and the base connection part are connected, the plurality of first docking teeth and the plurality of second docking teeth are staggered and engaged.

[0011] The base connection portion also includes a second connection seat and a base connection piece. The second connection seat is cylindrical, and the outer diameter of the second connection seat is not larger than the inner diameter of the first connection seat. The base connection piece is used to connect the base of a vehicle or a simulated racing car. One end of the second connection seat is fixedly connected to the base connection piece, and the outer surface of the other end is provided with a plurality of steel ball grooves for inserting steel balls. The plurality of steel ball grooves are evenly spaced along the circumference of the second connection seat, and the number of steel ball grooves is equal to the number of steel balls. The outer surface of the second connection seat close to one end of the base connection piece is provided with a plurality of second docking teeth. The second docking teeth are a structure protruding from the outer surface of the second connection seat, and the plurality of second docking teeth are arranged at intervals along the circumference of the second connection seat.

[0012] A positioning piece is provided on the steering wheel connection part, and a positioning groove is provided on the base connection part. During installation, anti-error installation is achieved by aligning the positioning piece and the positioning groove. The positioning groove is a groove provided on the outer surface of the second connecting seat. The positioning groove is located between two adjacent second docking teeth. The length direction of the positioning groove is parallel to the axial direction of the second connecting seat. One end of the positioning groove is on the end of the second connecting seat away from the base connecting piece, and the other end is in the middle of the second connecting seat. The positioning piece passes through a first docking tooth and protrudes from the inner surface of the first docking tooth.

[0013] A PCB circuit board is arranged in each of the first connecting seat and the base connecting part. When the steering wheel connecting part and the base connecting part are connected, the circuits of the PCB circuit board in the first connecting seat and the PCB circuit board in the base connecting part are connected by pins.

[0014] The bottom surface of the steel ball groove does not completely fit the steel ball, so that the pressure exerted by the steel ball on the second connecting seat is directed to one end of the steering wheel connecting piece.

[0015] The beneficial effects of the utility model are:

[0016] (1) It takes up less space and will not interfere with the steering wheel shift paddles, clutch paddles, etc. when installed on the steering wheel. It is easy to process and manufacture, and does not require the use of hard and difficult-to-process materials such as stainless steel.

[0017] (2) After the steering wheel connection part and the base connection part are connected, the rotation is transmitted through the engagement of the steel ball and the first docking teeth and the second docking teeth. The first docking teeth and the second docking teeth are staggered in contact and tightly fitted. The connection between the two is stable and not easy to shake after the connection.

[0018] (3) Through the cooperation of the second elastic member and the inner ring, the inner ring blocks one end of the steel ball hole on the first connecting seat, so that the steel ball blocks the reset of the pull ring. Therefore, when installing the steering wheel, there is no need to manually pull the pull ring or other components. It is only necessary to align the steering wheel connection part with the base connection part and insert it to allow the locking part to lock the steel ball. The installation is convenient, fast and labor-saving.

[0019] (4) The positioning parts and positioning slots are provided to prevent wrong insertion, thereby further improving the speed and accuracy of installation.

[0020] (5) The bottom surface of the steel ball groove does not completely fit the steel ball, so that the pressure exerted by the steel ball on the second connecting seat is parallel or substantially parallel to the horizontal plane, and the direction of the pressure points to one end of the steering wheel connector. The second connecting seat generates a reaction force of the same magnitude and opposite direction on the steel ball. In this way, the steel ball and the second connecting seat tend to be relatively pressed, further reducing the sliding and shaking after the steering wheel is installed.

[0030] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0032] A device for quickly installing and removing a steering wheel for a vehicle or a simulated racing car, such as Figure 1 As shown, it includes a steering wheel connection part 1 and a base connection part 2, one end of the steering wheel connection part 1 is connected to the steering wheel 6, and the other end is detachably connected to the base connection part 2, one end of the base connection part 2 is connected to the base 7 of the vehicle or simulated racing car, and the other end is detachably connected to the steering wheel connection part 1.

[0033] The steering wheel connection portion 1 includes a first connection seat 11, a pull ring 12, a first elastic member 13, a pull ring retaining ring 14, a steel ball 15, an inner ring 16, a second elastic member 17, a first docking tooth 18, and a steering wheel connection member 19. The first connection seat 11 is cylindrical, with the steering wheel connection member 19 coaxially and integrally connected to one end of the first connection seat 11. The cross-section of the steering wheel connection member 19 is triangular and is used to connect to the steering wheel 6. The steering wheel connection member 19 can be connected to the steering wheel 6 via three screws, taking up little space and not affecting the position design of the various paddle structures on the back of the steering wheel 6. The other end of the first connection seat 11 is connected to a plurality of first docking teeth 18. One end of the first docking teeth 18 is fixedly connected to the end surface of the first connection seat 11, and the other end extends away from the first connection seat 11. The plurality of first docking teeth 18 are arranged at intervals along the circumference of the first connection seat 11.

[0034] A plurality of through-hole steel ball holes are provided on the side wall of the middle portion of the first connecting seat 11 , that is, the steel ball holes pass through the side wall of the first connecting seat 11 . The plurality of steel ball holes are evenly spaced along the circumference of the first connecting seat 11 , and a steel ball 15 is placed in each steel ball hole.

[0035] The pull ring 12 is movably sleeved on the outside of the first connecting seat 11, and the inner ring 16 is movably set inside the first connecting seat 11. The pull ring 12 and the inner ring 16 limit or release the limit of the steel ball 15 from the inside and outside of the first connecting seat 11 respectively through their respective movements, so as to lock the steel ball 15 to prevent it from moving or release the lock of the steel ball 15 so that the steel ball 15 can move within a certain range.

[0036] The pull ring 12 is movably sleeved between the pull ring limiting protrusion 111 and the pull ring limiting retaining ring 14. Specifically, the outer surface of the middle portion of the first connecting seat 11 is provided with a pull ring limiting protrusion 111 and a pull ring limiting retaining ring 14. The pull ring limiting protrusion 111 is a protrusion fixedly provided on the outer surface of the first connecting seat 11, and the pull ring limiting protrusion 111 is arranged along the circumference of the first connecting seat 11. In other words, the pull ring limiting protrusion 111 is an annular structure coaxial with the first connecting seat 11, and the inner ring of the pull ring limiting protrusion 111 is sleeved on the outside of the first connecting seat 11. The outer surface of the middle portion of the first connecting seat 11 is also provided with a groove, which is arranged along the circumference of the first connecting seat 11. The groove and the pull ring limiting protrusion 111 are arranged at intervals. The groove is used to install the pull ring limiting retaining ring 14. After installation, the pull ring limiting retaining ring 14 protrudes from the outer surface of the first connecting seat 11. Preferably, the pull ring limiting protrusion 111 is located between the steering wheel connector 19 and the pull ring limiting retaining ring 14. The pull ring limiting protrusion 111 and the pull ring limiting retaining ring 14 play a limiting role, so that the pull ring 12 can only axially reciprocate between the pull ring limiting protrusion 111 and the pull ring limiting retaining ring 14.

[0037] A circle of the steel ball holes is located between the pull ring limiting protrusion 111 and the pull ring limiting retaining ring 14.

[0038] The pull ring 12 is resettable by the first elastic member 13. Specifically, the pull ring 12 is divided into three parts, namely, the elastic member matching part 121, the steel ball matching part 122 and the limiting part 123 which are sequentially connected along the axial direction. Figure 3 and 4As shown, the elastic member mating portion 121 is closer to the pull ring limiting protrusion 111 than the steel ball mating portion 122. The diameter of the inner surface of the elastic member mating portion 121 is larger than the outer diameter of the middle portion of the first connecting seat 11, so that a space for accommodating the first elastic member 13 is formed between the inner surface of the elastic member mating portion 121 and the outer surface of the first connecting seat 11. One end of the steel ball mating portion 122 is a locking portion 1221, and the other end is a steel ball groove portion 1222. The inner surface of the locking portion 1221 is in contact with the outer surface of the first connecting seat 11. The inner surface of the steel ball groove portion 1222 is provided with an annular groove that runs along the circumference of the inner surface of the pull ring 12. The groove is suitable for inserting the steel ball 15. In other words, the inner diameter of the steel ball groove portion 1222 is larger than the inner diameter of the locking portion 1221. The inner surfaces of the locking portion 1221 and the steel ball groove portion 1222 are smoothly connected and transitioned to form an inclined transition surface, that is, the inner diameter of the middle portion of the steel ball matching portion 122 gradually increases from the steering wheel connector 19 toward the base connector 2. The inner surface of the limiting portion 123 contacts and fits the first connecting seat 11, and the limiting portion 123 can contact the pull ring limiting retaining ring 14. The first elastic member 13 is located between the outer surface of the first connecting seat 11 and the elastic member matching portion 121. One end of the first elastic member 13 contacts the pull ring limiting protrusion 111, and the other end contacts the end surface of the steel ball matching portion 122. When the first elastic member 13 is in a natural state and is not subject to external force, the locking portion 1221 is opposite to and contacts the steel ball 15.

[0039] In order to facilitate manual operation of the pull ring 12 , a circular handle 124 protruding from the pull ring 12 is provided on the outer surface of the pull ring 12 .

[0040] Inner ring 16 is annular and positioned within first connector 11. Inner ring 16 is movable axially along first connector 11. One end of second elastic member 17 is fixed relative to first connector 11, while the other end contacts one end surface of inner ring 16. Second elastic member 17 is positioned between steering wheel connector 19 and inner ring 16. Furthermore, second elastic member 17 is positioned between steering wheel connector 19 and a circle of steel ball holes. When second elastic member 17 is in its natural state and not subject to external forces, inner ring 16 blocks one end of the steel ball holes on the inner surface of first connector 11, preventing steel balls 15 from falling out of the inner surface of first connector 11.

[0041] In this embodiment, the first elastic member 13 and the second elastic member 17 are both springs.

[0042] The base connection part 2 is as follows Figure 5As shown, it includes a second connecting seat 21, a base connecting member 22 and a plurality of second docking teeth 23. The second connecting seat 21 is cylindrical, and the outer diameter of the second connecting seat 21 is not greater than the inner diameter of the first connecting seat 11. The base connecting member 22 is fixedly connected to the base 7 of the vehicle or simulated racing car. One end of the second connecting seat 21 is fixedly connected to the base connecting member 22, and the outer surface of the other end is provided with a plurality of steel ball grooves 24 for inserting steel balls 15. The plurality of steel ball grooves 24 are evenly spaced along the circumference of the second connecting seat 21. The number of steel ball grooves 24 is equal to the number of steel balls 15. The outer surface of the second connecting seat 21 near one end of the base connecting member 22 is provided with a plurality of second docking teeth 23. The second docking teeth 23 are a structure protruding from the outer surface of the second connecting seat 21. The plurality of second docking teeth 23 are spaced along the circumference of the second connecting seat 21.

[0043] During the connection process between the steering wheel connection part 1 and the base connection part 2, under the elastic force of the first elastic member 13, the pull ring 12 will give the steel ball 15 a radial pressure directed toward the central axis of the first connection seat 11. Preferably, the bottom surface of the steel ball groove 24 or the groove surface of the steel ball groove 24 includes at least two curved surfaces with different curvatures, and each curved surface is smoothly connected, so that after the steering wheel connection part 1 and the base connection part 2 are connected, the bottom surface of the steel ball groove 24 does not completely fit the steel ball 15, and the pressure exerted by the steel ball 15 on the second connection seat 21 is parallel or substantially parallel to the horizontal plane, and the direction of the pressure is directed to one end of the steering wheel connection part 19. At this time, the second connection seat 21 generates a reaction force of the same size and opposite direction on the steel ball 15. In this way, the steel ball 15 and the second connection seat 21 tend to be relatively pressed, further reducing the sliding and shaking after the steering wheel 6 is installed. As Figure 9 As shown, the steel ball 15 contacts and presses against the left side portion a of the steel ball groove 24. The right side of the steel ball groove 24 is not in contact with the steel ball 15, with a gap b between them. Clearly, the pressure exerted by the steel ball 15 on the second connecting seat 21 is caused by the pressure exerted by the pull ring 12 on the steel ball 15.

[0044] After the steering wheel connection portion 1 and the base connection portion 2 are connected, the second connection seat 21 is inserted into the first connection seat 11. The plurality of first docking teeth 18 and the plurality of second docking teeth 23 are interlocked, i.e., each first docking tooth 18 is inserted between two adjacent second docking teeth 23, and each second docking tooth 23 is inserted between two adjacent first docking teeth 18. Preferably, the side surfaces of the first docking teeth 18 and the second docking teeth 23 are inclined surfaces. The side surface of the first docking tooth 18 refers to the surface of the first docking tooth 18 facing the adjacent first docking tooth 18. Similarly, the side surface of the second docking tooth 23 refers to the surface of the second docking tooth 23 facing the adjacent second docking tooth 23. After engagement, the side surface of the first docking tooth 18 contacts the side surface of the second docking tooth 23. The inclined side surface of the first docking tooth 18 creates a groove between two adjacent first docking teeth 18 that is approximately an isosceles trapezoid, with the end of the groove closer to the first connection seat 11 being smaller than the end farther away from the first connection seat 11. Similarly, the side surfaces of the second docking teeth 23 are inclined, so that the groove between two adjacent second docking teeth 23 is an isosceles trapezoid, and the end of the groove closer to the base connector 22 is smaller than the end farther away from the base connector 22. In this way, the first docking teeth 18 and the second docking teeth 23 can dock and engage smoothly, and after docking and tightening, the steering wheel connecting part 1 and the base connecting part 2 will not loosen or shake.

[0045] In addition, this solution has an anti-misinsertion design, which allows the operator to quickly and accurately align the steering wheel connection part 1 with the base connection part 2. Specifically, a positioning groove 25 is provided on the second connection seat 21. The positioning groove 25 is a groove provided on the outer surface of the second connection seat 21. The positioning groove 25 is located between two adjacent second docking teeth 23. The length direction of the positioning groove 25 is parallel to the axial direction of the second connection seat 21. One end of the positioning groove 25 is on the end of the second connection seat 21 away from the base connection member 22, and the other end is in the middle of the second connection seat 21. A positioning member 10 that can cooperate with the positioning groove 25 is provided on the first connection seat 11. The positioning member 10 passes through a first docking tooth 18 and protrudes from the inner surface of the first docking tooth 18. The inner surface of the first docking tooth 18 refers to the surface located on the side close to the inside of the first connection seat 11. In other words, the length direction of the positioning member 10 is parallel to a radial direction of the first connection seat 11. When the steering wheel connection part 1 is aligned with the base connection part 2 and the steering wheel connection part 1 is inserted into the base connection part 2, the base connection part 2 can be inserted into the steering wheel connection part 1 only when the positioning member 10 is aligned with the positioning groove 25. Specifically, one end of the positioning member 10 protruding from the inner surface of the first docking tooth 18 is inserted into the positioning groove 25 from one end of the positioning groove 25 at the end of the second connection seat 21, and the positioning member 10 moves relative to the positioning groove 25 along the length direction of the positioning groove 25. If the positioning member 10 is not aligned with the positioning groove 25, the positioning member 10 will be blocked by the end of the second connection seat 21, hindering the base connection part 2 from being inserted into the steering wheel connection part 1. Furthermore, the positioning groove 25 and the positioning member 10 are painted to facilitate faster identification. In this embodiment, the positioning member 10 is a top screw.

[0046] A PCB circuit board 5 is arranged in each of the first connecting seat 11 and the second connecting seat 21. Figure 3 As shown. When the steering wheel connection part 1 and the base connection part 2 are connected, the circuits of the PCB circuit board 5 in the first connection seat 11 and the PCB circuit board 5 in the second connection seat 21 are connected by pins, thereby realizing the circuit connection between the steering wheel 6 and the vehicle or the simulated racing car body. A sleeve 4 for mounting the PCB circuit board 5 is provided in the first connection seat 11. The sleeve 4 is cylindrical, and the PCB circuit board 5 is mounted in the sleeve 4. The sleeve 4 is sleeved in the first connection seat 11 and is connected to the first connection seat 11 through connecting wings protruding from its outer surface. The outer diameter of the sleeve 4 is smaller than the inner diameter of the first connection seat 11. The second elastic member 17 and the inner ring 16 are both located between the sleeve 4 and the first connection seat 11. The sleeve 4 provides support for one end of the second elastic member 17, that is, one end of the second elastic member 17 contacts the connecting wings at the end of the sleeve 4, and the other end contacts the inner ring 16.

[0047] Based on the above structure, the working principle and process of the present invention are as follows: when the steering wheel connecting part 1 is in the initial state, the inner ring 16 blocks the steel ball hole, and the steel ball 15 cannot exceed the inner surface of the first connecting seat 11. A part of the steel ball 15 is located in the steel ball hole, and the other part falls into the groove of the steel ball groove portion 1222. At this time, due to the obstruction of the steel ball 15, the first elastic member 13 is in a compressed state and cannot be reset. That is, at this time, the first elastic member 13 has a thrust on the pull ring 12, and the pull ring 12 has a thrust on the steel ball 15. Figure 4 shown.

[0048] The steering wheel connector 19 of the steering wheel connector 1 is fixedly connected to the steering wheel 6 by bolts. When the steering wheel 6 needs to be installed on a vehicle or a simulated racing car, the end of the steering wheel connector 1 with the first docking teeth 18 is aligned with the second connecting seat 21 and inserted, so that the second connecting seat 21 is inserted into the first connecting seat 11. When the second connecting seat 21 is pushed into the first connecting seat 11, the second connecting seat 21 can contact and push one end of the inner ring 16, such as Figure 7 As shown, when the second connecting seat 21 moves relative to the first connecting seat 11 until the multiple steel ball grooves 24 are aligned with the multiple steel balls 15, the multiple steel balls 15 are respectively inserted into the multiple steel ball grooves 24 under the push of the pull ring 12. A portion of each steel ball 15 is inserted into the steel ball groove 24, and the other portion remains in the steel ball hole of the first connecting seat 11. In this way, the second connecting seat 21 and the first connecting seat 11 are relatively fixedly connected together, wherein the thrust of the pull ring 12 on the steel ball 15 is provided by the first elastic member 13, and the first elastic member 13 pushes the pull ring 12 to move axially ( Figure 7 Move to the right in the middle), until the locking portion 1221 faces the steel ball 15 and pushes it into the steel ball groove 24 (as shown in FIG. Figure 8 (as shown). After connection, the steering wheel 6 can drive the base connection portion 2 to rotate synchronously. At this point, the steel ball 15 contacts the locking portion 1221 at one end and the second connection seat 21 at the other end. The steel ball 15 is locked by the pull ring 12 and the second connection seat 21 and cannot move. After connection, the multiple first docking teeth 18 and the multiple second docking teeth 23 interlock. In this way, the steering wheel connection portion 1 and the base connection portion 2 can transmit rotation not only through the steel ball 15, but also through the interlocking engagement of the first docking teeth 18 and the second docking teeth 23.

[0049] When removing the steering wheel 6 from the vehicle or racing car, the handle 124 is first pulled or pushed, moving it toward the end of the steering wheel connector 19. This compresses the first elastic member 13, and as the handle 124 moves, the locking portion 1221 disengages from the steel ball 15. The groove of the steel ball groove 1222 faces the steel ball 15, and the steel ball 15 is now unlocked and can move within a certain range and fall into the groove of the steel ball groove 1222. The steering wheel 6 with the steering wheel connector 1 is then removed. Since the steel ball 15 is now unlocked, the relative fixed connection between the second connecting seat 21 and the first connecting seat 11 is also released. During removal, the first connecting seat 11 moves relative to the second connecting seat 21, and the second connecting seat 21 can push a portion of the steel ball 15 into the groove of the steel ball groove 1222 without hindering the relative movement of the second connecting seat 21. Simultaneously, the inner ring 16 moves under the action of the compressed second elastic member 17, re-blocking the steel ball hole and preventing the steel ball 15 from falling out. Finally, after taking out the steering wheel 6, the handle 124 is released. At this time, due to the obstruction of the steel ball 15, the pull ring 12 cannot be reset, the first elastic member 13 remains in the compressed state, and the steering wheel connecting part 1 returns to the initial state.
