Description

Technical Field

[0001] This utility model relates to the field of photographic accessories technology, and in particular to a quick-release mount and a quick-release assembly for shooting and photography. Background Technology

[0002] Photography is becoming increasingly widespread in people's daily lives, used to document their experiences. Photography can be done using devices such as mobile phones and cameras. To make photography more convenient, these devices are often mounted on tripods, shoulder straps, or shoulder straps to produce better results. To allow for quick mounting and dismounting of the device from these devices, quick-release mechanisms are commonly used. These mechanisms typically consist of a quick-release base and a quick-release plate. The base connects to the device, and the plate connects to the tripod, shoulder strap, or shoulder strap. The quick-release base and plate engage quickly to mount the device. However, traditional quick-release mechanisms require a spring to pull back the clamp holding the plate during the transition from a locked to an unlocked state. This additional spring complicates the overall structure of the quick-release base and adds unnecessary cost. Utility Model Content

[0003] The present invention provides a quick-release mount and a quick-release assembly for shooting and photography, in order to solve the technical problem that the quick-release mount in the quick-release assembly also needs to be equipped with a spring to drive the clamping block to flip outward, which makes the overall structure of the quick-release mount more complicated.

[0004] First aspect This utility model discloses a quick-release base, comprising: Base; A turntable, rotatably connected to the base, has a mounting surface; A locking part is disposed on the turntable and rotates synchronously with the turntable. The locking part is used to fix the quick-release plate to the mounting surface. The locking part is provided with a first magnetic element. The base is provided with a second magnetic component, which includes a first magnetic end and a second magnetic end that are spaced apart. One of the first magnetic end and the second magnetic end is magnetically attracted to the first magnetic component, and the other is magnetically repelled by the first magnetic component. The turntable is rotatable relative to the base between a first position and a second position. When the turntable is in the first position, the first magnetic element interacts with the first magnetic end, causing the locking part to move forward relative to the mounting surface to fix the quick-release plate to the mounting surface. When the turntable is in the second position, the first magnetic element interacts with the second magnetic end, causing the locking part to move in the opposite direction relative to the mounting surface to release the quick-release plate.

[0005] In one embodiment, a stop block is provided on the mounting surface opposite to the locking part. When the turntable is in the first position, the locking part and the stop block are used together to clamp the quick-release plate.

[0006] In one embodiment, the turntable is provided with a channel for the latch to extend and retract, the channel being connected to the inner cavity of the base.

[0007] In one embodiment, the locking part is flipped on the turntable, and the locking part includes a locking block and a connecting block connected together. The locking block moves in and out of the channel as the locking part flips. The turntable has a limiting groove on the side facing away from the mounting surface for accommodating and fixing the connecting block. The limiting groove extends radially along the turntable, and one end of the limiting groove communicates with the channel.

[0008] In one embodiment, the first magnetic element includes a first magnet, the second magnetic element includes a second magnet and a third magnet, the first magnetic active end is formed on the second magnet, and the second magnetic active end is formed on the third magnet.

[0009] In one embodiment, there is one second magnet and two third magnets, with the two third magnets located on either side of the second magnet. When the turntable rotates forward from the first position, the first magnet interacts with the third magnet on one side, causing the locking part to retract into the mounting surface. When the turntable rotates in the reverse direction from the first position, the first magnet interacts with the third magnet on the other side, causing the locking part to retract into the mounting surface.

[0010] In one embodiment, the base is further provided with a locking member. When the turntable is in the first position, the locking member can be moved to engage with the turntable, thereby fixing the turntable in the first position; the locking member can also be moved in the opposite direction to release the engagement.

[0011] In one embodiment, a reset member is provided between the base and the turntable. The reset member accumulates or releases a reset force along the circumference of the turntable. The reset force released by the reset member can drive the turntable to automatically rotate and reset to the first position of the turntable.

[0012] In one embodiment, at the junction of the turntable and the base, one of the turntable and the base is provided with a locking block, and the other is provided with a locking groove. The locking block is radially aligned and engaged with the locking groove and can rotate within the locking groove. At least one of the locking block and the locking groove is annular.

[0013] In one embodiment, the slot is an annular slot, and the annular slot is provided with a first limiting block and a second limiting block that are circumferentially adjacent and spaced apart. When the turntable is in the first position, the slot abuts against the first limiting block on one side of the turntable's circumference; when the turntable is in the second position, the slot abuts against the second limiting block on the other opposite side of the turntable's circumference.

[0014] Second aspect This utility model provides a quick-release assembly for taking photographs, comprising: Quick-release plate for mounting shooting equipment; and As described in any of the preceding embodiments, the quick-release plate is fixed to the mounting surface by the locking portion.

[0015] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects: This utility model provides a quick-release base and a quick-release assembly for photography. The quick-release base and quick-release plate constitute the quick-release assembly. The quick-release base locks and unlocks the locking part by means of a turntable and a base rotating relative to each other, in conjunction with a magnetic component, thereby locking and releasing the quick-release plate. Since the quick-release base of this application drives the movement of the locking part solely through the interaction between the first and second magnetic components, compared to the traditional one-button trigger flip-locking locking part, the elastic structure connected to the locking part is eliminated. On the one hand, the volume and installation space of the magnetic component are smaller than those of the elastic component, simplifying the overall structure of the quick-release base to some extent and reducing unnecessary costs. On the other hand, the magnetic force of the magnetic component is independent of its volume (related to the material). Given a fixed installation space, users can choose magnetic components of different magnetic strengths, and the locking force of the same quick-release base can be changed by replacing the magnetic component to meet more user needs. Furthermore, regarding the unlocking process of the quick-release base, the user only needs to rotate the quick-release plate or the shooting device to rotate the turntable relative to the base, achieving one-click unlocking. Therefore, the quick-release base of this application does not require an additional unlocking button to achieve one-click unlocking, making operation convenient and quick, and further simplifying the overall structure of the quick-release base. In summary, the quick-release base of this application has the advantages of simplified structure, low processing cost, and convenient operation, improving the customer's operating experience and the practicality of the quick-release base.

[0019] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0020] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" 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 application based on the specific circumstances.

[0022] Reference Figure 1-4This application provides a quick-release assembly 1 for photographic equipment. The quick-release assembly 1 includes a quick-release base 10 and a quick-release plate 20 that can be quickly assembled. One of the quick-release base 10 and the quick-release plate 20 is used to install the shooting equipment, and the other is used to connect to a support device. The quick-release base 10 is used to fix the quick-release plate 20 and includes a base 100, a turntable 200, and a locking part 300. The base 100 serves as the supporting body of the quick-release base 10. The turntable 200 is rotatably connected to the base 100 and has a mounting surface 210 for assembling the quick-release plate 20. The mounting surface 210 is located on the side of the turntable 200 facing away from the base 100. The locking part 300 is disposed on the turntable 200 and rotates synchronously with the turntable 200. The locking part 300 is used to fix the quick-release plate 20 to the mounting surface 210. The locking part 300 is provided with a first magnetic element 410, and the base 100 is provided with a second magnetic element 420. The second magnetic element 420 includes a first magnetic end and a second magnetic end spaced apart. One of the first magnetic end and the second magnetic end is magnetically attracted to the first magnetic element 410, and the other is magnetically repelled by the first magnetic element 410. Here, the first magnetic element 410 and the second magnetic element 420 constitute a magnetic assembly 400, and the first magnetic end and the second magnetic end have opposite magnetic properties. The turntable 200 is rotatable relative to the base 100 between a first position and a second position. Figure 1 and Figure 3 This illustrates that when the turntable 200 is in the first position, the first magnetic component 410 is aligned with and interacts with the first magnetic end, causing the locking part 300 to move forward relative to the mounting surface 210 to fix the quick-release plate 20 to the mounting surface 210. Figure 2 and Figure 4 The illustration shows that when the turntable is in the second position, the first magnetic component 410 and the second magnetic end are aligned and interact, causing the locking part 300 to move in the opposite direction relative to the mounting surface 210 to release the quick-release plate 20. It is worth noting that both the first magnetic component 410 and the second magnetic component 420 can be combinations of magnets, or combinations of magnets and metal blocks. The requirement is that the second magnetic component 420 has two magnetically opposite ends, such that the force between the first magnetic component 410 and the first magnetic end is opposite to the force between the first magnetic component 410 and the second magnetic end.

[0023] It should be understood that the movement of the locking part 300 relative to the mounting surface 210 includes at least the following three situations: First, when the locking part 300 is laterally slidably connected to the turntable 200, the locking part 300 slides back and forth laterally relative to the mounting surface 210; Second, when the locking part 300 is longitudinally slidably connected to the turntable 200, the locking part 300 moves up and down relative to the mounting surface 210; Third, when the locking part 300 is rotatably connected to the turntable 200, the locking part 300 rotates up and down relative to the mounting surface 210.

[0024] The quick-release base 10 and quick-release assembly 1 provided by this utility model consist of a quick-release base 10 and a quick-release plate 20. The quick-release base 10, through the relative rotation between the turntable 200 and the base 100, cooperates with the magnetic component 400 to lock and unlock the latching part 300, thereby locking and releasing the quick-release plate 20. Since the quick-release base 10 of this application drives the movement of the latching part 300 only through the interaction between the first magnetic component 410 and the second magnetic component 420, compared with the traditional one-button trigger locking latching part 300, the elastic structure connected to the latching part 300 is eliminated. On the one hand, the volume and installation space of the magnetic component are generally smaller than those of the elastic structure, which simplifies the overall structure of the quick-release base 10 to a certain extent, reducing unnecessary costs. On the other hand, the magnetic force of the magnetic component is independent of its volume (related to the material). Given a fixed installation space, users can choose magnetic components with different magnetic strengths. The same quick-release base 10 can change the locking force by replacing the magnetic component to meet more user needs. Furthermore, regarding the unlocking process of the quick-release mount 10, the user only needs to rotate the quick-release plate 20 or the shooting device to rotate the turntable 200 relative to the base 100, achieving one-click unlocking. Therefore, the quick-release mount 10 of this application does not require an additional unlocking button to achieve one-click unlocking, making operation convenient and quick, and further simplifying the overall structure of the quick-release mount 10. In summary, the quick-release mount 10 of this application has the advantages of simplified structure, low processing cost, and convenient operation, improving the customer's operating experience and the practicality of the quick-release mount 10.

[0025] Alternatively, in one embodiment, in conjunction with reference to Figure 1 and Figure 2 A stop 220 is provided on the mounting surface 210, opposite to the locking part 300. When the turntable 200 is in the first position, the locking part 300 extends out of the mounting surface 210 and forms a clamping space with the stop 220, together clamping the quick-release plate 20. At this time, the user only needs to rotate the turntable 200 to the second position, and the locking part 300 retracts into the mounting surface 210 to release the quick-release plate 20. It should be noted that in other embodiments, the locking part 300 can extend out of the mounting surface and engage with the corresponding slot of the quick-release plate 20 to lock the quick-release plate 20 onto the mounting surface 210. In this case, the stop 220 is not required, and the quick-release plate 20 can be locked independently by the locking part 300. Therefore, in this application, the presence or absence of the stop 220 is not limited, and any structure in which the locking part 300 can lock the quick-release plate 20 after extending out of the mounting surface 210 should be included.

[0026] Alternatively, in one embodiment, in conjunction with reference 1 and Figure 2On the mounting surface 210, two guide blocks 230 are provided on the left and right sides of the locking part 300 and the stop block 220. The inner sides of the two guide blocks 230 form a first dovetail groove 240, which guides the quick-release plate 20 to slide into the mounting, allowing the quick-release plate 20 to slide and quickly connect with the quick-release seat 10. Here, the first dovetail groove 240 not only guides the sliding quick-release but also improves the tightness of the quick-release plate 20 with its dovetail edge, especially suitable for common AKA quick-release systems. Of course, in other embodiments, the presence or absence of guide blocks 230 and first dovetail grooves 240 is not limited. Optionally, in one embodiment, the quick-release plate 20 can also be circular, and the number of locking parts 300 can be multiple and distributed circumferentially along the turntable to enhance the assembly stability of the quick-release plate 20. Therefore, in this application, the shape of the quick-release plate 20 is not limited.

[0027] Furthermore, in one embodiment, combined with Figure 1 and Figure 2 The inner side of the stop block 220 and the inner side of the latching part 300 form a second dovetail groove 250. It can be understood that the locking end of the latching part 300 is hook-shaped to further improve the connection stability between the quick-release base 10 and the quick-release plate 20. Furthermore, the first dovetail groove 240 and the second dovetail groove 250 enclose a square assembly space, which can restrict the forward, backward, left, right, and circumferential swaying of the quick-release plate 20, thereby improving the assembly stability of the quick-release plate 20 and stabilizing the shooting position of the shooting device. It should be understood that in other embodiments, the latching part 300 and the stop block 220 can be upright blocks, and both can jointly clamp the quick-release plate 20 at the first position of the turntable 200. Therefore, the shapes of the latching part 300 and the stop block 220 are not limited, and the presence or absence of the second dovetail groove 250 is not limited.

[0028] Optionally, in one embodiment, combined with Figure 4 and Figure 5 The turntable 200 is provided with a channel 260 for the locking part 300 to extend and retract, and the channel 260 is connected to the inner cavity 110 of the base 100.

[0029] Optionally, in one embodiment, combined with Figure 4 and Figure 5The locking part 300 is rotatably mounted on the turntable 200. The locking part 300 includes a locking block 310 and a connecting block 320 connected together. The locking block 310 moves in and out of the channel 260 as the locking part 300 rotates. The turntable 200 has a limiting groove 270 on the side facing away from the mounting surface 210 for accommodating and fixing the connecting block 320. The limiting groove 270 extends radially along the turntable 200 to one end of the limiting groove 270, which connects to the channel 260. The limiting groove 270 limits the connecting block 320, thereby stably positioning the locking part 300 on one side of the turntable 200 and preventing the locking part 300 from shifting left or right during synchronous rotation with the turntable 200. In other words, the limiting groove 270 serves to prevent the locking part 300 from shifting. Here, the locking part 300 is mounted on the turntable 200 in a rocker-like posture, allowing it to swing up and down relative to the turntable 200. In other embodiments, the locking part 300 can be rotatably connected to one side of the turntable 200 via a shaft, with the shaft passing laterally through the middle of the locking part 300 and the turntable 200. This also allows the locking part 300 to be mounted on the turntable 200 in a rocker-like posture, eliminating the need for the limiting groove 270, while still providing anti-displacement functionality. Therefore, in this application, the presence or absence of the limiting groove 270 is not limited.

[0030] It should be noted that, since the locking part 300 is rotatably mounted on the turntable 200 in a rocker-like posture, in this embodiment, when the magnetic component 400 is positioned near the locking block 310, Figure 5 This illustrates that when the turntable 200 is in the first position, the first magnetic end of the first magnetic component 410 and the first magnetic end of the second magnetic component 420 are aligned and repulsed, causing the locking block 310 to flip inward to fix the quick-release plate 20 to the mounting surface 210. Figure 6 The diagram illustrates that when the turntable 200 is in the second position, the second magnetic ends of the first magnetic element 410 and the second magnetic element 420 are aligned and attracted, causing the locking block 310 to flip outward in the opposite direction to release the quick-release plate 20. Optionally, according to the rocker principle, in another embodiment, the magnetic component 400 can also be located on the side away from the locking block 310 (not shown). When the turntable 200 is in the first position, the first magnetic ends of the first magnetic element 410 and the second magnetic element 420 are aligned and attracted, causing the locking block 310 to flip inward in the forward direction to fix the quick-release plate 20 to the mounting surface 210; when the turntable 200 is in the second position, the first magnetic ends of the first magnetic element 410 and the second magnetic element 420 are aligned and repelled, causing the locking block 310 to flip outward in the opposite direction to release the quick-release plate 20.

[0031] Optimally, in one embodiment, combining Figure 3 and Figure 4The base 100 is provided with a locking member 500. When the turntable 200 is in the first position, the locking member 500 can be moved to engage with the turntable 200, thereby fixing the turntable 200 in the first position and restricting the relative rotation between the turntable 200 and the base 100. The locking member 500 can also be moved in the opposite direction to release the engagement, thereby releasing the rotation restriction of the turntable 200, and the turntable 200 rotates relative to the base 100 to the second position. In this embodiment, the edge of the turntable 200 is provided with a snap-fit ​​groove 280. The locking member 500 is slidably connected to the base 100. When the turntable 200 is in the first position, the locking member 500 can move radially relative to the base 100 along the turntable 200 to engage with the snap-fit ​​groove 280, thereby restricting the rotation of the turntable 200 and maintaining the locked state of the quick-release seat 10. When a user needs to unlock the quick-release base 10, they must first move the locking element 500 to release the rotation restriction of the turntable 200 before they can rotate the turntable 200 to unlock the quick-release base 10. Therefore, the locking element 500 serves to prevent accidental unlocking of the quick-release base 10. It should be noted that in other embodiments, the presence or absence of the locking element 500 is not limited; the presence or absence of the locking groove 280 is not limited. Any structure that enables the locking element 500 to engage and restrict the rotation of the turntable 200 should be included.

[0032] Alternatively, in one embodiment, in conjunction with reference to Figure 3 and Figure 7 A reset member 600 is provided between the base 100 and the turntable 200. The reset member 600 accumulates or releases a reset force along the circumference of the turntable 200. The reset force released by the reset member 600 can drive the turntable 200 to automatically rotate and reset to the first position, improving the ease of operation of the quick-release base 10. Of course, in other embodiments, the reset member 600 is not required, and the turntable 200 can be switched between the first and second positions by manually controlling the rotation.

[0033] Optionally, in one embodiment, reference is made to... Figure 3 , Figure 7 and Figure 8The turntable 200 rotates relative to the base 100 around the rotating shaft 700. The axis of the rotating shaft 700 is perpendicular to the mounting surface 210, that is, the axis of the rotating shaft 700 is parallel to the thickness direction of the base 100. The reset component 600 includes a telescopic spring 610. The inner cavity 110 of the base 100 is provided with an arc-shaped limiting groove 120, which surrounds the rotating shaft 700 and is used to house the telescopic spring 610, thereby limiting the lateral displacement of the telescopic spring 610 during extension and retraction. Here, the protrusion 101 of the base 100 is aligned and engaged with the limiting arc-shaped limiting groove 120. The two ends of the telescopic spring 610 are respectively connected to the inner sidewall of the arc-shaped limiting groove 120 and the protrusion 101, so that the telescopic spring 610 is connected between the turntable 200 and the base 100. In one embodiment, the reset component 600 includes a torsion spring (not shown), which is passed through the rotating shaft 700 and can also achieve circumferential force storage or release. Since the telescopic spring 610 and the torsion spring are positioned differently, this application only needs to use at least one of them to achieve the purpose of circumferential force storage or release. It should be understood that in other embodiments, the reset member 600 may also adopt a coil spring, elastic rubber, or other structure capable of providing circumferential reset force.

[0034] Alternatively, in one embodiment, in conjunction with reference to Figure 5 and Figure 6 At the connection point between the base 100 and the turntable 200, one of the turntable 200 and the base 100 is provided with a locking block 290, and the other is provided with a locking groove 130. The locking block 290 engages radially with the turntable 200 in the locking groove 130 and can rotate within the locking groove 130; at least one of the locking block 290 and the locking groove 130 is annular. It should be noted that the rotatable connection between the locking groove 130 and the locking block 290 here enables the turntable 200 to rotatably connect to the base 100. Combined with the rotating shaft 700, this further enhances the stability of the rotatable connection between the turntable 200 and the base 100. Moreover, the design of the locking block 290 and the locking groove 130 engaging radially with the turntable 200 provides a function to prevent rotational detachment. Therefore, in other embodiments, at least one of the two rotational methods, namely the rotating shaft 700 connection and the engagement of the locking groove 130 and the locking block 290, is sufficient; the engagement direction of the locking block 290 and the locking groove 130 is not limited.

[0035] Optionally, refer to Figure 7In one embodiment, the first magnetic element 410 includes a first magnet 411, and the second magnetic element 420 includes a second magnet 421 and a third magnet 422. A first magnetic action end is formed on the second magnet 421, and a second magnetic action end is formed on the third magnet 422. The second magnet 421 and the third magnet 422 have opposite magnetic properties. Of course, since magnets and metals can attract or repel each other, in other embodiments, the second magnet 421 and the third magnet 422 can be replaced by magnets and metals or steel ingots that repel each other, as long as one of the forces between the first magnet 411 and the second magnet 421 and the first magnet 411 and the third magnet 422 is attracted and the other is repelled. Alternatively, the second magnetic element 420 can also be composed of a bar magnet with opposing S and N poles (i.e., corresponding first and second magnetic action ends). When the turntable 200 is in the first position, the first magnetic element 410 interacts with one of the S / N poles; when the turntable 200 rotates 180 degrees to the second position, the first magnetic element 410 interacts with the other of the S / N poles. Therefore, in this application, the material and quantity of the first magnetic element 410 and the second magnetic element 420 are not limited.

[0036] Optionally, in one embodiment, the slot 130 is an annular groove 131, which is provided with a first limiting block (not shown) and a second limiting block 132 that are circumferentially adjacent. When the turntable 200 is in the first position, the locking block 290 abuts against the first limiting block on one side of the circumference; when the turntable 200 is in the second position, the locking block 290 abuts against the second limiting block 132 on the other side of the circumference. It should be noted that in this embodiment, the turntable 200 rotates unidirectionally relative to the base 100 to unlock, and there is only one third magnet 422. The two limiting blocks are set to prevent the turntable 200 from rotating excessively and to restrict the rotation of the turntable 200 between the first and second positions. Of course, in other embodiments, since the locking member 500 is set in the first position, it can also restrict the rotation of the turntable 200, so the first limiting block may not be required; in another embodiment, the turntable 200 rotates unilaterally to unlock, so the first limiting block is not required; in addition, the magnetic interaction of the three magnets has a positioning and limiting function. Therefore, in this application, the setting of the first limit block or the second limit block 132 is not limited.

[0037] Optionally, in one embodiment (double-sided rotation unlocking), combined with Figure 3 , Figure 4 and Figure 7The system has one second magnet 421 and two third magnets 422, located on opposite sides of the second magnet 421. When the turntable 200 rotates forward from the first position, the first magnetic element 410 interacts with the third magnet 422 on one side, causing the locking part 300 to retract into the mounting surface 210, thus unlocking the quick-release seat 10. When the turntable 200 rotates backward from the first position, the first magnetic element 410 interacts with the third magnet 422 on the other side, causing the locking part 300 to retract into the mounting surface 210, thus unlocking the quick-release seat 10. The arrangement of two third magnets 422 allows the quick-release seat 10 to be unlocked by rotating from both sides, improving user convenience. Of course, in other embodiments, the number of third magnets 422 is one, and the turntable 200 can also unlock the quick-release seat 10 by rotating from only one side.

[0038] Alternatively, in one embodiment, in conjunction with reference to Figure 5-8 The locking part 300 has a first placement groove 330 on the side facing away from the mounting surface 210 for accommodating the first magnetic component 410; the base 100 has a second placement groove 140 on the side facing the locking part 300 for accommodating the second magnet 421; and the base 100 has a third placement groove 150 on the side facing the locking part 300 for accommodating the third magnet 422. The first magnetic component 410, the second magnet 421, and the third magnet 422 do not protrude from their respective wall surfaces. When the turntable 200 is in the first position ( Figure 5 As shown), the first magnetic element 410 and the second magnet 421 are kept apart, aligned but not in contact, and interact with each other; when the turntable 200 is in the second position ( Figure 6 As shown, the first magnetic element 410 and the third magnet 422 are spaced apart, aligned but not in contact, and interact with each other. It should be noted that this non-contact magnetic interaction (attraction or repulsion) helps the user operate the turntable 200 to achieve rotational misalignment between the two magnets, making rotation of the turntable 200 less strenuous. Of course, in other embodiments, without considering the rotational force, whether the magnets are in contact is not limited.

[0039] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
