Description

Technical Field

[0001] This invention relates to the field of unmanned equipment technology, and more specifically, to a dispersing device, system, and unmanned equipment. Background Technology

[0002] Unmanned equipment, such as drones or unmanned vehicles, is widely used in plant protection technology, specifically for operations such as seed sowing and watering. Unmanned equipment used for sowing seeds, fertilizers, and other materials needs to be equipped with a sowing system. This system typically includes a hopper, a feeding device, and a sowing device. The hopper, connected to the sowing device via the feeding device, stores seeds and other materials. The feeding device transports the material from the hopper to the sowing device, which then spreads the material. The sowing device includes a motor and a rotating disc connected to the motor's drive. The motor drives the disc to oscillate back and forth, thus dispersing the material.

[0003] Existing seeding devices employ a swing-type swivel disc. The motor is connected to the disc via a crank-connecting rod mechanism. The motor only needs to rotate rapidly in one direction to drive the crank-connecting rod mechanism, converting the motor's circular motion into the reciprocating oscillation of the disc. However, this transmission method has a complex structure, faces numerous reliability challenges, and is costly. Summary of the Invention

[0004] This invention provides a novel oscillating spraying device with a spinning disc. The output shaft of a motor directly drives the spinning disc, and the reciprocating oscillation of the disc can be achieved by controlling the forward and reverse rotation of the motor's output shaft. However, using the forward and reverse rotation of the motor's output shaft to drive the spinning disc reciprocating requires the motor to constantly stop and accelerate in the opposite direction, resulting in extremely high power consumption and severe heat generation. This not only affects the battery's range of powering the motor but also easily burns out the motor.

[0005] The seeding device provided by this invention can be used in the seeding system of unmanned equipment. The seeding device can reduce the power consumption of the motor, improve the problem of severe motor overheating, thereby helping to extend the battery life that provides power to the motor, effectively improve the problem of motor burnout, and ensure that the elastic potential energy released by the elastic element is fully converted into the kinetic energy of the reverse swing of the disc.

[0020] In an optional embodiment, the elastic element includes a spring, with connectors at both ends of the spring. Each connector has a helical groove, and the connector is fixed to the spring when the spring's coil is screwed into the helical groove.

[0021] In an alternative embodiment, the connector is provided with a flange, and the end of the spring abuts against the flange, which is used to prevent the spring from displacing axially.

[0022] In an optional embodiment, the support member has a first side and a second side that are opposite to each other, the swivel disc is disposed on the first side, the motor is mounted on the second side, and the output shaft of the motor passes through the support member and is connected to the swivel disc.

[0023] In an optional embodiment, the slinger includes a disc body and a paddle connected to one side of the disc body. The output shaft of the motor is connected to the disc body. The paddle swings with the disc body and is used to spread the material. The elastic element is located on the side of the disc body away from the paddle.

[0024] In an optional embodiment, the support member is provided with a receiving groove, and the elastic member is at least partially located within the receiving groove.

[0025] In an optional embodiment, the spreading device further includes a shielding cover connected to the support member. The shielding cover is used to shield the opening of the receiving groove, and the elastic member and the throwing disc are located on opposite sides of the shielding cover.

[0026] In an optional implementation, the spreading device includes at least two elastic elements.

[0027] In an optional embodiment, at least two elastic elements include a first elastic element and a second elastic element. When the spinning disc is in the middle position, the length extension directions of both the first and second elastic elements point to the swing center of the spinning disc. When the first and second elastic elements release elastic potential energy, they can cooperate to drive the spinning disc to swing in the opposite direction.

[0028] In an optional embodiment, the first elastic element and the second elastic element are centrally symmetrically distributed about the swing center of the swivel disc.

[0033] The beneficial effects of the spreading device in this embodiment of the invention include: the spreading device provided in this embodiment of the invention includes a motor, a spinning disc, and an elastic element. The spinning disc is connected to the output shaft of the motor. When the spreading device is working, the output shaft of the motor drives the spinning disc to reciprocate through forward and reverse rotation. The first end of the elastic element is connected to a fixed position and rotatably connected to a solid at the fixed position. The second end of the elastic element is rotatably connected to the spinning disc or a oscillating element that oscillates synchronously with the spinning disc. When the spinning disc oscillates, the second end of the elastic element oscillates with the spinning disc. The oscillating motion of the spinning disc can be converted into axial deformation of the elastic element, and the elastic element can drive the spinning disc to oscillate in the opposite direction when releasing elastic potential energy. In this way, the variable length of the elastic element can be used to directly absorb and release energy during the circular motion of the spinning disc. The energy loss during the energy conversion process is small, that is, unnecessary energy loss is avoided, the energy conversion rate is improved, and more energy can be converted into the elastic potential energy of the elastic element. Thus, the elastic potential energy of the elastic element can be used to fully reduce the energy consumption of the motor driving the spinning disc to reciprocate.

[0034] The seeding system of this invention includes all the beneficial effects of the aforementioned seeding device. For example, it utilizes the variable length of the elastic element to directly absorb and release energy during the circular motion of the spinning disc. This results in less energy loss during the energy conversion process, thus avoiding unnecessary energy loss and improving the energy conversion rate. More energy can be converted into the elastic potential energy of the elastic element, thereby fully reducing the energy consumption of the motor-driven spinning disc reciprocating.

[0035] The unmanned equipment in this embodiment of the invention includes all the beneficial effects of the aforementioned seeding system. For example, by utilizing the variable length of the elastic element, energy is directly absorbed and released during the circular motion of the spinning disc. There is less energy loss during the energy conversion process, which avoids unnecessary energy loss and improves the energy conversion rate. More energy can be converted into the elastic potential energy of the elastic element, thereby making full use of the elastic potential energy of the elastic element to reduce the energy consumption of the motor-driven spinning disc reciprocating.

[0057] Please refer to Figure 1 This embodiment provides an unmanned device, which may refer to a drone; of course, in other embodiments, the unmanned device may also refer to an unmanned vehicle, which is not specifically limited here.

[0058] Please refer to Figure 1 and Figure 2 The unmanned equipment includes an unmanned equipment body and a spreading system 110 installed on the unmanned equipment body. Specifically, the unmanned equipment body includes a load support 100, and the spreading system 110 is mounted on the load support 100. The spreading system 110 includes a material bin 111, a feeding device 112, and a spreading device 020. The material bin 111 is mounted on the load support 100 and connected to the spreading device 020 via the feeding device 112. The material bin 111 is used to store seeds and other materials. The feeding device 112 receives the materials output from the material bin 111 and transports the received materials to the spreading device 020, which then spreads the materials. The unmanned equipment body can refer to the unmanned aerial vehicle (UAV) itself.

[0059] It should be understood that the feeding device 112 is not a necessary structure. In other embodiments, the material bin 111 may not be connected to the spreading device 020 through the feeding device 112. That is, the material output from the material bin 111 does not need to be conveyed by the feeding device 112, but falls directly to the spreading device 020 for spreading.

[0060] Please refer to Figure 2 and Figure 3 The spreading device 020 of this embodiment includes a material cover 113, a motor 200, a support member 400, and a slinging disc 300. The material cover 113 is provided with a material inlet 114 and is connected between the feeding device 112 and the support member 400. The slinging disc 300 is located between the material cover 113 and the support member 400. The motor 200 is mounted on the support member 400, and the output shaft of the motor 200 is connected to the slinging disc 300 for driving the slinging disc 300 to swing back and forth around its own swing center on both sides of a set axis a. The swinging slinging disc 300 can spread the material that falls from the material inlet 114 into the space between the material cover 113 and the support member 400.

[0061] Furthermore, the support member 400 has a first side and a second side distributed opposite to each other. The first side is distributed opposite to the material cover 113. The slinger 300 is disposed on the first side, and the motor 200 is mounted on the second side. The output shaft of the motor 200 passes through the support member 400 and is connected to the slinger 300. This arrangement improves the integration of the spreading device 020.

[0062] The slinging disc 300 includes a disc body 310 and a paddle 320 connected to one side of the disc body 310. The output shaft of the motor 200 is connected to the disc body 310. The paddle 320 is distributed opposite to the material inlet 114 and swings with the disc body 310 to scatter the material.

[0063] Alternatively, in some embodiments, the motor 200 can be connected to the swivel disc 300 via a reducer 201, which is not specifically limited here.

[0064] In related technologies, the output shaft of motor 200 is used to drive the swivel disc 300 to swing back and forth in both forward and reverse directions. This requires motor 200 to stop and accelerate in reverse frequently, resulting in extremely high power consumption and severe heat generation of motor 200. This not only affects the battery life that provides power to motor 200, but also easily burns out motor 200.

[0065] To improve the above issues, please refer to Figure 4The spreading device 020 in this embodiment also includes an elastic element 510. The first end of the elastic element 510 is connected to a fixed position and rotatably connected to a solid at the fixed position. Specifically, the first end of the elastic element 510 is rotatably connected to a support member 400, i.e., the solid at the fixed position refers to the support member 400. The second end of the elastic element 510 is rotatably connected to a swaying disc 300 or a swaying member that swings synchronously with the swaying disc 300. When the swaying disc 300 swings, the second end of the elastic element 510 swings with the swaying disc 300, and at the same time, the second end also rotates around the position to which it is connected. The first end of the elastic element 510 does not swing with the swaying disc 300, but it also rotates around the fixed position to which it is connected. Thus, the elastic element 510 can always maintain a straight shape during the swinging process of its second end. The swinging motion of the swaying disc 300 can be converted into the axial deformation of the elastic element 510, and the elastic element 510 can drive the swaying disc 300 to swing in the opposite direction when releasing elastic potential energy. This configuration allows the elastic deformation of the elastic element 510 to absorb and store energy, enabling the elastic element 510 to match the oscillation frequency of the swivel disc 300. This assists the swivel disc 300 in deceleration and reverse acceleration, reducing energy consumption during sudden stops and reverse acceleration of the motor 200. It also improves the problem of severe overheating of the motor 200, thereby extending the battery life that powers the motor 200 and effectively mitigating the problem of motor burnout. Furthermore, there is no need to set up additional motion conversion mechanisms to convert the circular motion of the swivel disc 300 into linear motion (e.g., slide rail assembly, gear rack, etc.). The variable length of the elastic element 510 allows for direct absorption and release of energy during the circular motion, avoiding unnecessary energy loss. More energy can be converted into the elastic potential energy of the elastic element 510, thus effectively reducing the energy consumption of the motor 200 driving the swivel disc 300 to reciprocate.

[0066] Further, please refer to Figure 5 Extending along the length of the swing axis of the swivel disc 300, the elastic element 510 is located between the support member 400 and the swivel disc 300. Specifically, the elastic element 510 is positioned on a plane parallel to the swing plane of the swivel disc 300. The elastic element 510 is located on the side of the disc body 310 of the swivel disc 300 away from the paddle 320, and the direction of the elastic force provided by the elastic element 510 is perpendicular to the output shaft axis of the motor 200. This arrangement avoids interference from the elastic element 510 in distributing materials by the swivel disc 300 and ensures that the elastic potential energy of the elastic element 510 is converted as much as possible into the power for the reverse swing of the swivel disc 300, thus improving efficiency.

[0067] Of course, in other embodiments, the elastic element 510 may also be disposed on a plane that is not parallel to the swing plane of the swivel disc 300.

[0068] Alternatively, in other embodiments, the first end of the elastic member 510 may also be rotatably connected to the load support 100, etc., without being specifically limited here.

[0069] In this embodiment, please refer to Figure 5 and Figure 6 The swinging component includes a swing arm 610 mounted on the output shaft of the motor 200. The swing disc 300 is connected to the output shaft of the motor 200 via the swing arm 610. The second end of the elastic element 510 is rotatably connected to the end of the swing arm 610. With this configuration, the elastic element 510 can reliably drive the swing disc 300 to swing in the opposite direction.

[0070] Furthermore, the spreading device 020 includes two elastic elements 510, namely a first elastic element 511 and a second elastic element 512. Along the length extension direction of the swing axis of the spinning disc 300, a swing arm 610 is located between the support member 400 and the spinning disc 300. The middle part of the swing arm 610 is connected to the output shaft of the motor 200, and the middle part of the swing arm 610 is also drive-connected to the spinning disc 300, so that the output shaft of the motor 200 is drive-connected to the disc body 310 of the spinning disc 300 through the swing arm 610. The two ends of the swing arm 610 along its length extension direction are respectively connected to the second end of the first elastic element 511 and the second end of the second elastic element 512. With this configuration, the two elastic elements 510 can reliably drive the spinning disc 300 to swing in opposite directions.

[0071] It should be understood that in other embodiments, the number of elastic elements 510 can be increased or decreased as needed, for example: please refer to Figure 7 The spreading device 020 includes an elastic element 510; or, please refer to Figure 8 The spreading device 020 includes four elastic elements 510, etc., which are not specifically limited here.

[0072] The connection method between the output shaft of the motor 200 and the swing arm 610, and the connection method between the swing arm 610 and the swivel disc 300, include but are not limited to plug-in, snap-fit, and welding, and are not specifically limited here.

[0073] It should be understood that in other embodiments, the swing arm 610 is connected to the output shaft of the motor 200, but not to the swivel disc 300, that is, the swivel disc 300 is not connected to the output shaft of the motor 200 via the swing arm 610.

[0074] In some implementation methods, please refer to Figure 9 and Figure 10 The output shaft of motor 200 is connected to the swing arm 610 via the output shaft of reducer 201. The swing arm 610 is connected to the swing plate 300, so that the driving force of motor 200 can be transmitted to swing plate 300 through reducer 201 and swing arm 610 to drive swing arm 610 and swing plate 300 to swing synchronously.

[0075] In this embodiment, please refer to Figure 6 The first elastic element 511 and the second elastic element 512 are centrally symmetrically distributed about the swing center of the swing disc 300. When the swing disc 300 swings, the radial forces exerted by the first elastic element 511 and the second elastic element 512 on the output shaft of the motor 200 can cancel each other out, and the first elastic element 511 and the second elastic element 512 extend or shorten synchronously. In this way, the shaft breakage problem can be improved, that is, the radial component of the force exerted by the first elastic element 511 on the output shaft of the motor 200 and the radial component of the force exerted by the second elastic element 512 on the output shaft of the motor 200 cancel each other out, reducing the risk of shaft breakage caused by the radial force pulling on the output shaft of the motor 200.

[0076] Of course, in embodiments where there are two or more elastic elements 510, it is not necessary for the multiple elastic elements 510 to be centrally symmetrically distributed around the swing center of the swing disc 300. That is, in other embodiments, the multiple elastic elements 510 do not need to be centrally symmetrically distributed around the swing center of the swing disc 300. For example, in other embodiments, the multiple elastic elements 510 may be distributed on the same side of the set axis a; or, in other embodiments, the multiple elastic elements 510 may be asymmetrically distributed on both sides of the set axis a; or, the multiple elastic elements 510 may be symmetrically but not centrally symmetrically distributed on both sides of the set axis a, etc., without specific limitations here.

[0077] In this embodiment, please refer to Figure 6When the spinning disc 300 is in the middle position, the length extension direction of the elastic element 510 points to the swing center of the spinning disc 300. Specifically, when the spinning disc 300 is in the middle position, the length extension directions of both the first elastic element 511 and the second elastic element 512 point to the swing center of the spinning disc 300, and the length extension directions of the first elastic element 511 and the second elastic element 512 coincide and are perpendicular to the set axis a. The first elastic element 511 and the second elastic element 512 are distributed symmetrically and at intervals along the horizontal direction on both sides of the set axis a. When the spinning disc 300 swings, the swing of the spinning disc 300 is converted into the axial deformation of the two elastic elements 510 respectively. When the two elastic elements 510 release elastic potential energy, they can cooperate to drive the spinning disc 300 to swing in the opposite direction. This configuration ensures that the two elastic elements 510, when releasing their elastic potential energy, are not in a state of mutual antagonism but rather cooperate with each other. This improves the problem of decreased energy conversion rate, specifically addressing the issue that the elastic potential energy released by one elastic element 510 is simultaneously converted into the kinetic energy of the slinger 300 and the elastic potential energy of the other elastic element 510. This further reduces the problem of less elastic potential energy from the elastic element 510 being converted into the kinetic energy of the slinger 300, ensuring that the motor 200 reliably reduces power consumption. Furthermore, the centripetal installation of the elastic elements 510 ensures that regardless of the direction the slinger 300 swings, the first elastic element 511 and the second elastic element 512 will extend simultaneously. The elastic potential energy released by both the first and second elastic elements 511 and 512 can provide the torque needed to restore the slinger 300 to its neutral position, thus ensuring that the first elastic element 511 and the second elastic element 512 cooperate with each other rather than antagonize each other.

[0078] Of course, in other embodiments, when the spinning disc 300 is in the middle position, the length extension direction of the elastic element 510 may not point to the swing center of the spinning disc 300; or, in other embodiments, when the spinning disc 300 is in the middle position, the length extension directions of the first elastic element 511 and the second elastic element 512 both point to the swing center of the spinning disc 300, the first elastic element 511 and the second elastic element 512 are symmetrically or asymmetrically distributed on both sides of the set axis a, and the length extension direction of the first elastic element 511 and the length extension direction of the second elastic element 512 do not coincide, nor are they perpendicular to the set axis a, which is not specifically limited here.

[0079] The two elastic elements 510 in this embodiment (i.e., the first elastic element 511 and the second elastic element 512) are similar in their own structure and in their connection with the swing arm 610 and the support 400. Only one of the elastic elements 510 will be described in detail here.

[0080] In this embodiment, please refer to Figure 5 , Figure 11 and Figure 12The elastic element 510 has a connector 520 at its second end, and the connector 520 has a first shaft hole 521. The swing arm 610 includes two spaced-apart clamping arms 611, each with a second shaft hole 612. The connector 520 is inserted between the two clamping arms 611, and the first shaft hole 521 and the second shaft hole 612 are opposite to each other and a first rotating shaft 613 passes through them. This arrangement ensures easy assembly and stable assembly of the elastic element 510 and the swing arm 610, and ensures that the second end of the elastic element 510 can rotate smoothly around the first rotating shaft 613.

[0081] Furthermore, the support member 400 includes a radial mounting wall 411 disposed on the output shaft of the motor 200, with a fixed position located on the mounting wall 411, and the second end of the elastic member 510 rotatably connected to the mounting wall 411. This arrangement ensures that the elastic member 510 is reliably disposed between the slinger 300 and the support member 400, effectively preventing the elastic member 510 from interfering with the slinger 300 in spreading materials.

[0082] Furthermore, a connecting seat 420 is provided at the fixed position of the mounting wall 411, and the first end of the elastic element 510 is rotatably connected to the support member 400 through the connecting seat 420. The setting of the connecting seat 420 ensures the reliability of the rotatable connection between the first end of the elastic element 510 and the fixed position.

[0083] Optionally, the first end of the elastic element 510 is also provided with a connector 520, and the connecting seat 420 is provided with a insertion hole 421 and a third shaft hole 422 communicating with the insertion hole 421. The connector 520 at the first end of the elastic element 510 is inserted into the insertion hole 421, and the first shaft hole 521 and the third shaft hole 422 are opposite to each other and a second rotating shaft 423 is passed through it. This arrangement ensures the ease of assembly and the stability of the assembly of the elastic element 510 and the connecting seat 420, and ensures that the first end of the elastic element 510 can rotate smoothly around the second rotating shaft 423.

[0084] The connection method between any end of the elastic element 510 and the corresponding connector 520 can be selected as needed; please refer to [reference needed]. Figure 5 and Figure 11 In this embodiment, the elastic element 510 includes a spring, and both ends of the spring are provided with connectors 520. Each connector 520 is provided with a helical groove 522. When the spring's coil is screwed into the helical groove 522, the connector 520 is fixed to the spring. This design ensures the ease of connection between the spring and the connector 520, as well as the stability after connection.

[0085] Furthermore, the connector 520 is connected to a retaining flange 523, and the end of the spring can abut against the retaining flange 523. The retaining flange 523 is used to prevent the spring from displacing along its axial direction. This design not only improves the stress concentration problem of the spring, but also ensures that the spring can adapt well to various complex and harsh working conditions such as vibration, high-frequency tension, and impact, thus greatly improving the life and reliability of the spring.

[0086] Of course, in other embodiments, the elastic element 510 includes a spring, and the connector 520 connected to its end is a hook formed by the spring itself; or, in other embodiments, the connector 520 is a hook, and the end of the spring is wound to form a constricted structure so that the hook is embedded in the constricted structure at the end of the spring, thereby reducing the problem of spring stress concentration.

[0087] In other embodiments, the elastic element 510 may also include elastic strips, etc., which are not specifically limited here.

[0088] In this embodiment, please refer to Figure 5 The support member 400 is provided with a receiving groove 410, and the elastic member 510 is at least partially located within the receiving groove 410. The groove wall of the receiving groove 410 is the aforementioned mounting wall 411, and the connecting seat 420 is connected to the groove wall of the receiving groove 410. The receiving groove 410 provides a smaller space for accommodating the elastic member 510 and allows the elastic member 510 to swing within the receiving groove 410. Assembling the elastic member 510 in a relatively small space makes it easier to seal and protect it compared to assembling it in a large space. For example, the size of the cover 430 connected to the support member 400 to cover the receiving groove 410 can be made smaller.

[0089] Furthermore, the connecting seat 420 is integrally formed onto the groove wall of the receiving groove 410. Of course, in other embodiments, the connection method between the connecting seat 420 and the groove wall of the receiving groove 410 can also be bonding, fastening with bolts or other fasteners, etc., which are not specifically limited here.

[0090] Furthermore, both elastic elements 510 are embedded in the receiving groove 410, that is, both the first elastic element 511 and the second elastic element 512 are embedded in the receiving groove 410.

[0091] Furthermore, please refer to Figure 5 and Figure 13 The spreading device 020 also includes a shielding cover 430, which is connected to the support member 400 and is used to shield the opening of the receiving groove 410. The elastic member 510 and the slinging disc 300 are located on opposite sides of the shielding cover 430. This arrangement allows the shielding cover 430 to shield the elastic member 510, reducing interference from the material and ensuring that the elastic member 510 reliably releases its elastic potential energy to drive the slinging disc 300 to swing in the opposite direction.

[0092] The connection methods between the cover 430 and the support 400 include, but are not limited to, snap-fit ​​and connection by fasteners such as bolts.

[0093] In this embodiment, both the first elastic element 511 and the second elastic element 512 are in a stretched state when the swivel disc 300 is stationary, and are also in a stretched state when oscillating; that is, the first elastic element 511 and the second elastic element 512 are in a stretched state whether they are stationary or oscillating, which is beneficial to improving the state stability of the first elastic element 511 and the second elastic element 512, and to ensuring the consistency of the elastic force provided by the first elastic element 511 and the second elastic element 512.

[0094] Of course, in other embodiments, the first elastic element 511 and the second elastic element 512 are both in a stretched state when the spinning disc 300 swings, and in a natural state (i.e., neither stretched nor compressed) when the spinning disc 300 is stationary; this setting can extend the service life of the first elastic element 511 and the second elastic element 512.

[0095] Alternatively, in other embodiments, the first elastic element 511 and the second elastic element 512 are both in a compressed state when the swivel disc 300 is stationary, and in a stretched state when it is oscillating.

[0096] It should be understood, please refer to Figure 14 In other embodiments, the second end of the elastic element 510 may also be connected to a position of the swivel disc 300 away from its swing center, and the elastic direction provided by the elastic element 510 is not perpendicular to the axial direction of the output shaft of the motor 200. For example, the second end of the first elastic element 511 and the second end of the second elastic element 512 are both connected to a position of the swivel disc 300 away from its swing center, and the first elastic element 511 and the second elastic element 512 are respectively located on both sides of the set axis a. When the swivel disc 300 swings, one of the first elastic element 511 and the second elastic element 512 extends and the other shortens. In this way, the first elastic element 511 and the second elastic element 512 can also be used to jointly drive the swivel disc 300 to swing in the opposite direction.

[0097] It should be noted that the stretching and shortening of each elastic element 510 in this embodiment refers to the change in its length, not the change in its elasticity. That is, stretching and compression do not mean that the elastic element 510 is in a state of providing tension or thrust.

[0098] The unmanned equipment in this embodiment can use the seeding system 110 to seed particulate materials such as seeds. The specific seeding process includes: the motor 200 drives the spinning disc 300 to swing back and forth, and during the swinging process of the spinning disc 300, the elastic element 510 undergoes elastic deformation, and the elastic potential energy released when the elastic element 510 recovers can be used to drive the spinning disc 300 to swing in the opposite direction.

[0099] In summary, the spreading device 020 of the present invention can be used in the spreading system 110 of unmanned equipment. The spreading device 020 can reduce the power consumption of the motor 200, improve the problem of severe heat generation of the motor 200, and thus help extend the battery life that provides power to the motor 200, effectively improving the problem of motor 200 burnout; moreover, it can ensure that the elastic potential energy released by the elastic member 510 is fully converted into the kinetic energy of the reverse swing of the swivel disc 300.

[0100] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
