Description

TECHNICAL FIELD

[0001] The present application relates to the field of connectors, in particular to a locking and anti-loosening mechanism for a connector. BACKGROUND

[0002] The disengagement connector is usually used to realize the connection of the plug and the socket, and the connector usually comprises one of the plug and the socket for connecting with the external socket or plug. Taking the connector provided with the socket as an example, the socket on the connector is connected with the external plug. Since there is a gap between the socket and the plug, the socket and the plug are prone to loosening, and the connector needs to realize the locking and unlocking between the plug and the socket through the locking mechanism. The locking mechanism comprises a transmission pin, and the transmission shaft is rotated in different directions to realize the compression or decompression between the socket and the plug, so as to realize the locking and unlocking of the connector.

[0003] In the vibration environment, the transmission shaft is kept in place by the friction between the transmission threads, but the friction is small, and when the vibration level is high, the transmission shaft will loosen, affecting the cooperation between the plug and the socket.

[0004] In order to realize the anti-loosening of the connector, the fuse (thin steel wire, thin rope, etc.) or the anti-loosening pin is usually used to avoid the loosening of the transmission shaft. When the plug is reinserted, the fuse and the anti-loosening pin need to be removed first, and then the plug is reinserted, and the fuse or the anti-loosening pin is inserted again, which is inconvenient to operate. SUMMARY

[0005] The present application is proposed to overcome the deficiencies of the prior art, and a locking and anti-loosening mechanism for a connector is provided to solve the technical problem of inconvenient operation of the anti-loosening structure in the locking mechanism of the connector in the prior art.

[0006] In order to realize the above technical target, the locking and anti-loosening mechanism for the connector comprises a fixed disc, a rotating disc rotatable relative to the axis of the fixed disc, and a transmission shaft, the transmission shaft is connected with the connector, the fixed disc is sleeved between the transmission shaft and the rotating disc, the fixed disc is provided with a through hole in the radial direction, the through hole is provided with an anti-loosening assembly, the anti-loosening assembly comprises a stop head which can be extended and retracted in the radial direction of the fixed disc, the transmission shaft is provided with a plurality of tooth grooves in the circumferential direction, the rotating disc is rotatable relative to the fixed disc between a first position and a second position, When the rotating disc is in the first position, the stop head can be extended and retracted in the radial direction of the fixed disc; When the rotating disc is in the second position, the rotating disc presses the anti-loosening assembly to limit the retraction of the stop head, and the stop head is stopped in the tooth groove to limit the rotation of the transmission shaft.

[0007] The locking and anti-loosening mechanism of the connector of the present invention has an anti-loosening component provided in the radial through hole of the fixed plate. The rotating plate can rotate relative to the fixed plate between a first position and a second position. When the rotating plate is in the first position, the stop head can extend and retract radially on the fixed plate, so that the drive shaft can rotate freely relative to the fixed plate. This allows the operator to rotate the drive shaft to lock or unlock the connector. When the rotating plate is in the second position, the anti-loosening component restricts the rotation of the drive shaft, thereby locking the connector in the locked position and preventing loosening. The locking and anti-loosening mechanism can achieve free rotation or locking of the drive shaft simply by switching the position of the rotating plate, which is convenient to operate.

[0008] Preferably, the anti-loosening component includes a top post, a top block, and a first elastic element. The top post and the top block can move radially along the fixed disk in the through hole. The stop head is disposed at the end of the top post away from the top block. The first elastic element is disposed between the top post and the top block so that the stop head can extend and retract radially in the fixed disk. The rotating disk is in a second position, and the rotating disk presses against the top block. The elastic force of the first elastic element restricts the retraction of the stop head. Alternatively, the top block stops the top post and restricts the retraction of the stop head.

[0009] By adopting the aforementioned technical solution, a structure is used to enable the stop head of the anti-loosening component to extend and retract radially relative to the through hole in the fixed plate, thereby reducing the design difficulty of the anti-loosening component.

[0010] Preferably, the anti-loosening component includes a top post and a first elastic element. The stop head is disposed at one end of the top post near the drive shaft, and the other end of the top post is provided with a top head that cooperates with the rotating disk. The top post also includes a circumferentially protruding support ring. The hole wall of the through hole near the drive shaft extends inward to form a limiting ring. The limiting ring divides the through hole into a first through hole and a second through hole that penetrates the limiting ring. The first elastic element is disposed between the support ring and the limiting ring. The stop head slides in the second through hole and extends and retracts radially in the fixed disk. The rotating disk is in the second position, and the rotating disk presses against the top head to restrict the retraction of the stop head.

[0011] By adopting the aforementioned technical solution, another structure is used to enable the stop head of the anti-loosening component to extend and retract radially relative to the through hole in the fixed plate, thereby reducing the design difficulty of the anti-loosening component.

[0012] Preferably, the rotating disk includes a base disk and a boss protruding from the base disk toward the fixed disk, the base disk having a first surface facing the fixed disk. The boss has a second surface higher than the first surface, and the rotating disk is in a second position where the second surface presses against the anti-loosening component.

[0013] By adopting the aforementioned technical solution, by setting a boss on the rotating disk that protrudes towards the fixed disk, the rotating disk can have different mating relationships with the anti-loosening component in the first and second positions, thus simplifying the design difficulty of the rotating disk.

[0014] Preferably, the second surface is arranged in an arc shape concentric with the rotation axis of the rotating disk.

[0015] By adopting the aforementioned technical solution, the straight-line distance between the second surface and the rotation axis of the rotating disk remains unchanged when the second surface rotates, so that the second surface can exert a consistent pressure on the anti-loosening component throughout the entire process of contacting the anti-loosening component.

[0016] Preferably, the fixed disk has a limiting groove on the side facing the rotating disk, and the rotating disk has a positioning component. Part of the positioning component is located in the limiting groove. The limiting groove has a first end and a second end that are spaced apart along the circumference of the fixed disk. The limiting groove has a positioning groove at the first end and the second end respectively that cooperates with the positioning component. The positioning component is located at the first end to place the rotating disk in a first position, and the positioning component is located at the second end to place the rotating disk in a second position.

[0017] By adopting the aforementioned technical solution, the positioning component cooperates with the limiting groove on the fixed plate to enable the rotating plate to rotate between the first and second positions relative to the fixed plate.

[0018] Preferably, the positioning component includes a housing, a positioning head, and a second elastic element. The second elastic element is pre-tightened between the housing and the positioning head so that the positioning head can extend and retract relative to the housing. The positioning head cooperates with the positioning groove to achieve positioning.

[0019] Using the aforementioned technical solution, the extension and retraction of the positioning head gives it a distinct tactile feel when entering and exiting the positioning groove. This allows the operator to more clearly know whether the rotating disk is in the first or second position. At the same time, the positioning head is pushed against the positioning groove by the pre-tightening force of the second elastic element, making it difficult for the rotating disk to detach from the first or second position.

[0020] Preferably, the device also includes a handwheel that is axially spaced from the fixed disk and is non-rotatably connected to the drive shaft.

[0021] By adopting the aforementioned technical solution, a handwheel is set at an axial distance from the fixed plate, and the handwheel is non-rotatably connected to the drive shaft. The operator can lock or unlock the connector by rotating the handwheel to drive the drive shaft to rotate. The operation is simpler and less strenuous for the operator.

[0022] Preferably, the drive shaft rotates in a first direction to lock the connector, and rotates in a second direction opposite to the first direction to unlock the connector. The tooth groove includes a first sidewall facing the first direction and a second sidewall facing the second direction. The first sidewall is constructed as a steep slope, and the second sidewall is constructed as a gentle slope.

[0023] By adopting the aforementioned technical solution, the drive shaft can tighten the connector with less effort, but loosen it with more effort. As a result, when the locking and anti-loosening mechanism locks the connector and the rotating disk is in the second position, it is more difficult for the drive shaft to push the anti-loosening component back, thereby further improving the anti-loosening capability of the locking and anti-loosening mechanism.

[0024] Preferably, the rotating disk is sleeved on the outside of the fixed disk, the fixed disk has a central hole in its axial direction, and the transmission shaft is sleeved in the central hole.

[0025] By adopting the aforementioned technical solution, the rotating disk is located on the outermost side, making it convenient for operators to operate; the drive shaft is located on the innermost side, which protects the drive shaft from external dust and moisture corrosion.

[0026] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0030] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" or "a number" means two or more, unless otherwise expressly defined.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] Example 1: like Figures 1 to 8 As shown, the locking and anti-loosening mechanism for the connector proposed in this embodiment of the invention includes a fixed disk 100, a rotating disk 200 rotatable relative to the axis of the fixed disk 100, and a drive shaft 300. The drive shaft 300 drives and connects the connector. The fixed disk 100 is sleeved between the drive shaft 300 and the rotating disk 200. The fixed disk 100 has a through hole 110 in its radial direction, and an anti-loosening component 400 is provided in the through hole 110. The anti-loosening component 400 includes a stop head 411 that can extend and retract in the radial direction of the fixed disk 100, and the drive shaft 300 has a plurality of toothed grooves 310 in its circumferential direction that cooperate with the stop head 411.

[0034] The rotation of the drive shaft 300 in one direction can cause the socket on the connector to press the plug, thereby locking the connector. The rotation of the drive shaft 300 in another direction can cause the socket on the connector to release the plug, thereby unlocking the connector.

[0035] The rotating disk 200 can rotate relative to the fixed disk 100 between a first position and a second position. In the first position, the stop head 411 can extend and retract radially on the fixed disk 100. When the drive shaft 300 rotates, the toothed groove 310 pushes the stop head 411 back, allowing the drive shaft 300 to rotate relative to the fixed disk 100, thereby locking or unlocking the connector. In the second position, the rotating disk 200 presses against the anti-loosening component 400, restricting the retraction of the stop head 411. The stop head 411 stops in the toothed groove 310, restricting the rotation of the drive shaft 300.

[0036] The locking and anti-loosening mechanism also includes a flange 700, a fixed plate 100 fixedly disposed relative to the flange 700, a rotating plate 200 rotatably connected to the flange 700, and a drive shaft 300 passing through the flange 700 for drive connection with the connector, so that the rotation of the drive shaft 300 causes the connector to be in a locked or unlocked state.

[0037] The locking and anti-loosening mechanism of the present invention has an anti-loosening component 400 provided in the radial through hole 110 of the fixed disk 100. The rotating disk 200 can rotate relative to the fixed disk 100 between a first position and a second position. When the rotating disk 200 is in the first position, the stop head 411 can extend and retract radially in the fixed disk 100, so that the transmission shaft 300 can rotate freely relative to the fixed disk 100. This allows the operator to rotate the transmission shaft 300 to lock or unlock the connector. When the rotating disk 200 is in the second position, the anti-loosening component 400 restricts the rotation of the transmission shaft 300, thereby locking the connector in the locked position and preventing loosening. The locking and anti-loosening mechanism can achieve free rotation or locking of the transmission shaft 300 simply by switching the position of the rotating disk 200, which is convenient to operate.

[0038] Example 2: Based on Example 1, such as Figures 4 to 7 As shown in this embodiment, one structure of the anti-loosening component 400 is described. The anti-loosening component 400 includes a top post 410, a top block 420, and a first elastic member 430. The top post 410 and the top block 420 can move radially along the fixed disk 100 in the through hole 110. A stop head 411 is disposed at the end of the top post 410 away from the top block 420. The first elastic member 430 is disposed between the top post 410 and the top block 420 so that the stop head 411 can extend and retract radially in the fixed disk 100. The rotating disk 200 is in a second position. The rotating disk 200 presses the top block 420 to compress the first elastic member 430. The elastic force of the first elastic member 430 restricts the stop head 411 from retracting.

[0039] The top post 410 and the top block 420 are slidably engaged with the through hole 110. The top block 420 is used to engage with the rotating disk 200. When the rotating disk 200 is in the first position, there is a large gap between the top block 420 and the top post 410, which allows the stop head 411 to extend and retract radially in the fixed disk 100. The rotational tendency of the drive shaft 300 can cause the tooth groove 310 to push the stop head 411 back out of the tooth groove 310, so that the drive shaft 300 can rotate relative to the fixed disk 100. The elastic element can be compressed and released, thereby allowing the stop head 411 to extend and retract radially in the fixed disk 100. When the rotating disk 200 is in the second position, the top block 420 is pressed by the rotating disk 200, which reduces the gap between the top block 420 and the top column 410, and puts the first elastic member 430 in a compressed state. The elastic force of the first elastic member 430 restricts the stop head 411 from retracting and disengaging from the tooth groove 310, so that the stop head 411 stops in the tooth groove 310 and restricts the rotation of the transmission shaft 300.

[0040] In some other embodiments, the top block 420 may stop the top post 410, thereby limiting the retraction of the stop head 411. Specifically, the top block 420 is compressed by the rotating disk 200, reducing the gap between the top block 420 and the top post 410. This gap is so small that the retraction of the stop head 411 cannot disengage from the tooth groove 310.

[0041] In this embodiment, the first elastic element 430 is a compression spring.

[0042] In this embodiment, a structure is used to enable the stop head 411 of the anti-loosening component 400 to extend and retract radially relative to the through hole 110 in the fixed plate 100, thereby reducing the design difficulty of the anti-loosening component 400.

[0043] Example 3: Based on Embodiment 1, another structure of the anti-loosening component 400 will be described, which differs from Embodiment 2 in that, as Figure 8 As shown, in this embodiment, the anti-loosening component 400 includes a top post 410 and a first elastic element 430. A stop head 411 is disposed at one end of the top post 410 near the drive shaft 300. The other end of the top post 410 is provided with a top head 412 that cooperates with the rotating disk 200. The top post 410 also includes a circumferentially protruding support ring 414. The hole wall of the through hole 110 near the drive shaft 300 extends inward to form a limiting ring 120. The limiting ring 120 divides the through hole 110 into a first through hole 111 and a second through hole 112 that penetrates the limiting ring 120. The first elastic element 430 is disposed between the support ring 414 and the limiting ring 120. The stop head 411 slides in the second through hole 112 and extends and retracts radially in the fixed disk 100. The rotating disk 200 is in the second position. The rotating disk 200 presses the top head 412 and restricts the stop head 411 from retracting.

[0044] The diameter of the second through hole 112 is smaller than that of the first through hole 111, and the support ring 414 slides in the first through hole 111. The rotational tendency of the drive shaft 300 causes the tooth groove 310 to push the stop head 411 back and disengage from the tooth groove 310, thereby enabling the drive shaft 300 to rotate relative to the fixed disk 100.

[0045] The top column 410 also includes a connecting rod 413 that connects the stop head 411 and the top head 412, and a support ring 414 is provided to protrude in the circumferential direction of the connecting rod 413.

[0046] In some other embodiments, the first elastic element 430 may also be pre-tightened between the support ring 414 and the limiting ring 120. The elastic force of the first elastic element 430 causes the stop head 411 to retract and have a certain distance from the tooth groove 310, so that the stop head 411 does not restrict the rotation of the drive shaft 300 relative to the fixed disk 100.

[0047] When the rotating disk 200 is in the second position, the rotating disk 200 presses the top head 412, causing the top column 410 to move toward the drive shaft 300. The stop head 411 extends into the second through hole 112 and stops in the tooth groove 310, thereby restricting the rotation of the drive shaft 300.

[0048] In this embodiment, the first elastic element 430 is a compression spring.

[0049] In this embodiment, the stop head 411 of the anti-loosening component 400 can extend and retract radially relative to the through hole 110 in the fixing plate 100 through another structure, thereby reducing the design difficulty of the anti-loosening component 400.

[0050] Example 4: Based on embodiments one to three, such as Figures 4 to 7 As shown, in this embodiment, the rotating disk 200 includes a base disk 210 and a boss 220 protruding from the base disk 210 toward the fixed disk 100. The base disk 210 has a first surface 211 facing the fixed disk 100, and the boss 220 has a second surface 221 higher than the first surface 211. The rotating disk 200 is in a second position, and the second surface 221 presses against the anti-loosening component 400.

[0051] The second surface 221 being higher than the first surface 211 means that, based on the first surface 211 and with the direction of the protrusion of the boss 220 as the height direction, the second surface 221 is higher than the first surface 211 in this height direction.

[0052] The boss 220 can be integrally formed on the base plate 210, and the boss 220 can also be fixedly connected to the base plate 210.

[0053] Since the first surface 211 is lower than the second surface 221, when the rotating disk 200 is in the first position, there is a certain gap between the anti-loosening component 400 and the first surface 211. This gap allows the stop head 411 to extend and retract radially in the fixed disk 100. When the rotating disk 200 is in the second position, the second surface 211 is higher than the first surface 211, thereby reducing the range of motion of the stop head 411 and thus limiting the retraction of the stop head 411.

[0054] By providing a boss 220 protruding towards the fixed disk 100 on the rotating disk 200, the rotating disk 200 can have different mating relationships with the anti-loosening component 400 in the first position and the second position, which simplifies the design difficulty of the rotating disk 200.

[0055] In this embodiment, three sets of anti-loosening components 400 are provided, and the three sets of anti-loosening components 400 are circumferentially spaced on the fixed disk 100. Correspondingly, three bosses 220 are provided, and the three bosses 220 are circumferentially spaced on the rotating disk 200. The three bosses 220 are respectively corresponding to the three sets of anti-loosening components 400.

[0056] In this preferred embodiment, the first surface 211 and the second surface 221 are smoothly connected.

[0057] Specifically, the boss 220 also has a transition surface 222 connecting the first surface 211 and the second surface 221. The height of the transition surface 222 gradually increases from the first surface 211 to the second surface 221, and the transition surface 222 smoothly transitions to the first surface 211 and the second surface 221 respectively.

[0058] This design reduces the resistance between the rotating disk 200 and the anti-loosening component 400 when the disk 200 rotates, making the rotation of the disk 200 easier and smoother.

[0059] In another preferred embodiment, the second surface 221 is arranged in an arc shape concentric with the rotation axis Z1 of the rotating disk 200.

[0060] With this configuration, the straight-line distance between the second surface 221 and the rotation axis Z1 of the rotating disk 200 remains constant when the second surface 221 rotates, so that the second surface 221 can exert a consistent pressure on the anti-loosening component 400 throughout the entire process of contacting the anti-loosening component 400.

[0061] Example 5: Based on Examples 1 to 4, such as Figures 1 to 3 As shown, in this embodiment, the fixed disk 100 is provided with a limiting groove 130 on the side facing the rotating disk 200, and the rotating disk 200 is provided with a positioning component 500. Part of the positioning component 500 is located in the limiting groove 130. The limiting groove 130 has a first end 131 and a second end 132 that are spaced apart along the circumference of the fixed disk 100. The limiting groove 130 is provided with positioning grooves 133 that cooperate with the positioning component 500 at the first end 131 and the second end 132, respectively. The positioning component 500 is located at the first end 131 to make the rotating disk 200 a first position, and the positioning component 500 is located at the second end 132 to make the rotating disk 200 a second position.

[0062] By cooperating with the positioning component 500 and the limiting groove 130 on the fixed disk 100, the rotating disk 200 can rotate relative to the fixed disk 100 between the first position and the second position.

[0063] In this preferred embodiment, the positioning component 500 includes a housing 510, a positioning head 520, and a second elastic member (not shown). The second elastic member is pre-tightened between the housing 510 and the positioning head 520 so that the positioning head 520 can extend and retract relative to the housing 510. The positioning head 520 cooperates with the positioning groove 133 to achieve positioning.

[0064] In this embodiment, the second elastic element is a compression spring, and the positioning head 520 is a steel column.

[0065] The extension and retraction of the positioning head 520 gives it a distinct tactile feel when entering and exiting the positioning groove 133, allowing the operator to more clearly know whether the rotating disk 200 is in the first or second position. At the same time, the positioning head 520 is pushed against the positioning groove 133 by the pre-tightening force of the second elastic element, making it difficult for the rotating disk 200 to disengage from the first or second position.

[0066] In some other embodiments, the limiting groove 130 may be disposed on the rotating disk, and the positioning component 500 may be disposed on the fixed disk.

[0067] Example 6: Based on Examples 1 to 5, such as Figure 1 , Figure 2 As shown, in this embodiment, the locking and anti-loosening mechanism also includes a handwheel 600 that is axially spaced from the fixed disk 100, and the handwheel 600 is non-rotatably connected to the transmission shaft 300.

[0068] In this embodiment, the drive shaft 300 is provided with a connecting groove 313, and the handwheel 600 is connected to the drive shaft 300 by a connecting key 610, so that the handwheel 600 and the drive shaft 300 are non-rotatably connected.

[0069] In some other embodiments, the handwheel 600 and the drive shaft 300 can also be fixedly connected. The fixed connection methods include, but are not limited to, radial connection with screws, riveting, snap-fitting, etc.

[0070] The outer diameter of the handwheel 600 is larger than the diameter of the drive shaft 300.

[0071] When the rotating disk 200 is in the first position, the operator can rotate the handwheel 600 to drive the drive shaft 300 to rotate, thereby locking or unlocking the connector. After locking the connector, the operator can rotate the rotating disk 200 to the second position. Since the drive shaft 300 is restricted from rotating by the anti-loosening component 500, the connector is restricted to the locked state, and correspondingly, the handwheel 600 cannot be rotated either.

[0072] By setting a handwheel 600 that is axially spaced from the fixed plate 100 and is non-rotatably connected to the drive shaft 300, the operator can lock or unlock the connector by rotating the handwheel 600 to drive the drive shaft 300 to rotate, making the operation simpler and less strenuous.

[0073] Example 7: Based on Examples 1 to 6, such as Figures 4 to 8As shown, in this embodiment, the drive shaft 300 rotates in a first direction to lock the connector, and rotates in a second direction opposite to the first direction to unlock the connector. The toothed groove 310 includes a first sidewall 311 facing the first direction and a second sidewall 312 facing the second direction. The first sidewall 311 is constructed as a steep slope, and the second sidewall 312 is constructed as a gentle slope.

[0074] refer to Figure 4 , Figure 6 As shown, the first direction is the counterclockwise rotation direction, and the second direction is the clockwise rotation direction.

[0075] Specifically, the center line of the cross-section of the first sidewall 311 and the tooth groove 310 forms an angle α, and the center line of the cross-section of the second sidewall 312 and the tooth groove 310 forms an angle β, where α < 45° and β > 45°.

[0076] In this embodiment, α = 35° and β = 60°.

[0077] In some other embodiments, α and β may also be other angles.

[0078] It should be noted that the centerline of the cross-section of the tooth groove 310 refers to the line connecting the bottom of the tooth groove 310 and the axis of the drive shaft 300. When the bottom of the groove is an arc-shaped surface, the lowest point of the arc-shaped surface is connected to the axis of the drive shaft 300. When the bottom of the groove is a plane, the center of the plane is connected to the axis of the drive shaft 300. When the bottom of the groove is an irregular surface, its lowest point is connected to the axis of the drive shaft 300.

[0079] With the above settings, the drive shaft 300 requires less effort when locking the connector and more effort when unlocking it. As a result, when the locking anti-loosening mechanism locks the connector and the rotating disk 200 is in the second position, it is more difficult for the drive shaft 300 to push the anti-loosening component 400 back, further improving the anti-loosening capability of the locking anti-loosening mechanism.

[0080] Example 8: Based on Examples 1 to 7, such as Figure 1 As shown, in this embodiment, the rotating disk 200 is sleeved on the outside of the fixed disk 100, the fixed disk 100 has a central hole in its axial direction, and the transmission shaft 300 is sleeved in the central hole.

[0081] In this way, the rotating disk 200 is on the outermost side, making it convenient for operators to operate; the drive shaft 300 is on the innermost side, which protects the drive shaft 300 from external dust and moisture corrosion.

[0082] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
