Description

Technical Field

[0001] This application belongs to the field of joystick technology, and more specifically, relates to a joystick, a handle, and an arcade game. Background Technology

[0002] The joystick controls in-game actions through the directional output of its axis. Specifically, the joystick includes a joystick ball, a joystick axis, four microswitches, and a circuit board. The four microswitches are located in the four cardinal directions of the joystick axis: forward, backward, left, and right. Adjacent microswitches form four diagonal directions: left-forward, left-backward, right-forward, and right-backward. The four microswitches are electrically connected to the circuit board and correspond to control in eight directions: the four cardinal directions and the four diagonal directions. Moving the joystick ball in a specific direction causes the joystick axis to rotate, triggering one or two microswitches, and the circuit board outputs the corresponding directional control. For example, moving the joystick ball forward causes the joystick axis to rotate, triggering the microswitch located directly behind the joystick, and the circuit board outputs directional control for forward movement. Similarly, moving the joystick ball to the right front causes the joystick axis to rotate, triggering the two microswitches located to the left and rear, and the circuit board outputs directional control for right front movement.

[0003] Existing joysticks use spring-loaded microswitches, which consist of a spring and a contact. The joystick shaft triggers the microswitch by pressing the contact against the spring. Because these microswitches have a relatively long spring (compared to the contact size), arranging four microswitches allows the joystick shaft to easily and effectively trigger both forward and diagonal microswitches, achieving directional output in eight directions. However, using spring-loaded microswitches results in significant noise, especially when using the joystick at home at night, as the noise can disturb family members and neighbors. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a joystick, handle and arcade machine that aims to achieve directional output control in eight directions while reducing the noise of joystick operation.

[0005] To achieve the above objectives, the embodiments of this application provide the following technical solutions: A joystick, comprising: Base; A rocker shaft is rotatably connected to the base, and the rocker shaft is fitted with a trigger and a limiting element. A micro switch is fixed on the base. There are four micro switches, which are respectively located in the four positive directions of the trigger. Four oblique directions are formed between two adjacent micro switches. Each micro switch is a mechanical axis push button switch and includes a fixed base and a key shaft protruding from the fixed base. The key shaft can trigger the micro switch when it is pressed by the trigger. A retaining ring is used to limit the rotation angle of the rocker arm shaft; The rocker arm axis has a positive rotation angle and an oblique rotation angle. The positive rotation angle refers to the maximum rotation angle of the rocker arm axis in any positive direction, and the oblique rotation angle refers to the maximum rotation angle of the rocker arm axis in any oblique direction, satisfying the following: tanθ1=K*tanθ2, 0.67≤K<1, Wherein, θ1 is the positive rotation angle of the rocker axis, and θ2 is the oblique rotation angle of the rocker axis.

[0006] Optionally, the joystick satisfies the following conditions: the forward rotation angle is less than the oblique rotation angle, the forward rotation angle is 7.5°-9°, and the oblique rotation angle is 8.1°-11°.

[0007] Optionally, the trigger element is cylindrical and the gap S between its outer surface and the key shaft satisfies: mm.

[0008] Optionally, the trigger element is cylindrical and the gap S between its outer surface and the key shaft satisfies: mm.

[0009] Optionally, the trigger element is cylindrical and satisfies: , Where r is the radius of the trigger element, and B is the distance from the surface of the key shaft facing the trigger element to the center of the rocker shaft.

[0010] Optionally, the fixing seat is provided with a fixing strip on its periphery, and the base is provided with a fixing groove that cooperates with the fixing strip.

[0011] Optionally, the base includes a substrate and limiting members connecting the substrate. There are four limiting members and they are arranged corresponding to the micro switch. Each limiting member includes a first baffle and a second baffle located on both sides of the micro switch. Both the first baffle and the second baffle are provided with the fixing groove.

[0012] Optionally, the rocker arm includes a circuit board, and the micro switch is electrically connected to the circuit board via a conductive sheet; The conductive sheet has a fixing groove at one end away from the circuit board. When the fixing strip is inserted into the fixing groove, the pin of the micro switch is placed into the fixing groove.

[0013] A handle, including a joystick as described above.

[0014] An arcade machine, including a joystick as described above.

[0015] The advantages of the joystick, handle, and arcade machine provided in this application are as follows: Compared with the prior art, the joystick provided in this application uses a mechanical shaft push-button switch instead of the existing spring-loaded microswitch, which can effectively reduce the noise of the joystick and improve its lifespan. By limiting the rotation angle of the joystick axis, eight-directional output control can be achieved, and it is ensured that the microswitch in the positive direction will not be damaged when the joystick is used for diagonal control operations.

[0022] 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 that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] Please combine Figures 1 to 9 The joystick provided in this application, as well as the handle and arcade machine using the joystick, are described by way of example.

[0024] The joystick includes a base 10, a joystick shaft 20 rotatably connected to the base 10, and a microswitch 30 fixed to the base 10. It is understood that the joystick also includes a circuit board 50 and a retaining ring 40.

[0025] Please refer to Figure 3 and Figure 4 A rocker ball 22 is fixed to the top of the rocker shaft 20. The rocker ball 22 is used for pushing, pulling, and rotating by hand. The rocker ball 22 and the rocker shaft 20 can be integrally formed from the same material, or they can be two structural parts fixedly connected by welding or other methods, or they can be two structural parts connected by screws. There is no limitation here.

[0026] A hemispherical component 23 is fitted onto the rocker shaft 20. The base plate 11 has a spherical groove that mates with the hemispherical component 23. The hemispherical component 23 is placed in the spherical groove and can rotate omnidirectionally relative to the spherical groove, so that the rocker shaft 20 can rotate omnidirectionally relative to the base plate 11. The center of the spherical groove / hemispherical component 23 is the rotation center of the rocker shaft 20.

[0027] A centering member 24, typically a spring, is fitted onto the rocker shaft 20. The centering member 24 keeps the rocker shaft 20 centered and perpendicular to the base plate 11. When the rocker shaft 20 rotates under external force, the centering member 24 undergoes elastic deformation. After the external force disappears, the centering member 24, under the action of elastic restoring force, returns the rocker shaft 20 to its centered state.

[0028] A trigger element 21 and a limiting element 25 are sleeved on the rocker shaft 20. The trigger element 21 is used to press against the micro switch 30, and the limiting element 25 cooperates with the retaining ring 40 to limit the rotation angle of the rocker shaft 20. In this embodiment, the trigger element 21 and the limiting element 25 are integrally formed. In other embodiments, the trigger element 21 and the limiting element 25 may also be two independent structural components that are fixed to the rocker shaft 20 by welding or snap-fitting, which is not limited here.

[0029] Combination Figure 4 In terms of orientation, the hemispherical component 23 is located at the top of the rocker shaft 20, and the centering component 24, the trigger component 21, and the limiting component 25 are sequentially sleeved on the rocker shaft 20 and rotate synchronously with the rocker shaft 20.

[0030] Please refer to Figure 2 and Figure 4 The microswitch 30 has four parallel ring joystick axes 20. The microswitch 30 is electrically connected to the circuit board 50, which can be achieved through wires, conductive plates 51, or other conductors. The microswitch 30 has two states: on and off. Under normal conditions, the microswitch 30 is in the off state. When the microswitch 30 is triggered, it sends a direction signal to the circuit board 50. The circuit board 50 receives the direction signal and outputs the corresponding directional control for the game.

[0031] Please refer to Figure 3 and Figure 4The retaining ring 40 is detachably connected to the base 10. The retaining ring 40 is used to limit the rotation angle of the rocker shaft 20. In this embodiment, the retaining ring 40 and the base 10 are screwed together by fasteners. In other embodiments, the retaining ring 40 and the base 10 can also be connected by snap-fit ​​or other means, which is not limited here. In this embodiment, the retaining ring 40 and the base 10 are located on both sides of the micro switch 30, and the retaining ring 40 and the base 10 are detachably connected to enclose and fix the micro switch 30 within it. The detachable connection of the retaining ring 40 and the base 10 facilitates the assembly and subsequent maintenance of the micro switch 30. The retaining ring 40 has a limiting hole 401 in the center, which limits the maximum angle that the rocker shaft 20 can rotate, thereby effectively preventing the micro switch 30 from being damaged by excessive rotation angle of the rocker shaft 20.

[0032] With the base 10 placed horizontally as a reference, four microswitches 30 are located in the four positive directions of the joystick axis 20: forward, backward, left, and right. Adjacent microswitches 30 form four diagonal directions: left-forward, left-backward, right-forward, and right-backward. The four microswitches 30 are electrically connected to the circuit board 50 and correspond to control in eight directions, namely the four positive directions and the four diagonal directions. An external force moves the joystick ball 22 in a specific direction, causing the joystick axis 20 to rotate, thus triggering one or two microswitches 30. The circuit board 50 then outputs the corresponding directional control. For example, moving the joystick ball 22 forward causes the joystick axis 20 to rotate, triggering the microswitch 30 located directly behind it, and the circuit board 50 outputs directional control for the game to move forward. Similarly, moving the joystick ball 22 to the right front causes the joystick axis 20 to rotate, triggering the two microswitches 30 located to the left and rear, and the circuit board 50 outputs directional control for the game to move to the right front.

[0033] In this embodiment, each micro switch 30 is a mechanical shaft button and includes a fixed base 31 and a key shaft 32 protruding from the fixed base 31. The rocker shaft 20 rotates relative to the base 10 and presses against the key shaft 32 of one or two micro switches 30 to trigger the micro switch 30.

[0034] Mechanical key switches are an existing design, available in various types such as brown, blue, white, black, red, and silver. They are commonly used in computer mechanical keyboards. Figure 7 and Figure 8Two types of mechanical axis push-button switches are shown. The mechanical axis push-button switch includes a base 31, a key shaft 32, a spring, and pins mounted on the base 31. The key shaft 32 slides on the base 31. There are two pins, one of which is a spring plate. When the spring plate abuts against the other pin, the microswitch 30 is triggered. The key shaft 32 has a plate, and the key shaft 32 is elastically connected to the base 31 via a spring. Under no external force, the plate of the key shaft 32 separates the two pins, keeping the microswitch 30 in the closed state. At this time, the spring plate is in an elastic deformation state. When the key shaft 32 is pressed into the base 31 under external force, the plate moves downward, and the spring plate returns to its original position under the action of elastic restoring force, abutting against the other pin, thereby triggering the microswitch 30. After the external force is removed, the key shaft 32 returns to its original position under the action of the spring, causing the microswitch 30 to return to the closed state.

[0035] Mechanical axis push-button switches use low voltage (3.3V~5V) and low current (1mA~10mA), and are characterized by no mechanical noise and long life (70 million cycles).

[0036] The joystick provided in this embodiment, as well as the handle and arcade machine using the joystick, uses a mechanical shaft button switch instead of the existing spring-loaded micro switch 30, which can effectively reduce the noise of the joystick and improve its lifespan.

[0037] In this embodiment, the retaining ring 40 has a limiting hole 401. When the wall of the limiting hole 401 abuts against the limiting member 25, it restricts the further rotation of the rocker shaft 20. In other words, the wall of the limiting hole 401 limits the maximum angle that the rocker shaft 20 can rotate. For example, when a person moves the rocker ball 22 to the left, the rocker shaft 20 rotates to the left with the center of rotation of the hemispherical member 23 as the center of rotation. The trigger member 21 presses against the micro switch 30 on its right side and triggers the micro switch 30. After the rocker shaft 20 rotates to the left to a specific angle, the limiting member 25 abuts against the retaining ring 40, thus restricting the further rotation of the rocker shaft 20. This specific angle is the maximum angle of the rocker shaft 20 in this direction (leftward rotation).

[0038] It should be noted that when the limiting hole 401 is circular, the maximum angle of rotation of the rocker arm 20 from the center position in all directions is the same. However, when the limiting hole 401 is irregularly shaped, the maximum angle of rotation of the rocker arm 20 in different directions may be different.

[0039] The maximum rotation angle of the joystick axis 20 needs to be set to ensure that it can trigger the target microswitches 30 corresponding to the forward and diagonal directions without damaging other microswitches 30. The joystick is used to output operation signals in eight directions; therefore, this embodiment focuses on describing the rotation angles in these eight directions. Four microswitches 30 are located in the four forward directions of the trigger 21, with the diagonal direction forming a 45° angle with the forward direction. Since the four microswitches 30 are located in the four forward directions of the trigger 21, the distance / rotation angle required for the joystick axis 20 to trigger the microswitches 30 from the forward direction is relatively small (equivalent to the right-angled side of a right triangle), while the distance / rotation angle required for the joystick axis 20 to simultaneously trigger two microswitches 30 from the diagonal direction is relatively large (equivalent to the hypotenuse of a right triangle). When the limiting hole 401 is circular (the maximum angle of rotation of the rocker shaft 20 from the center position is the same in all directions), if the diameter of the limiting hole 401 is small, the maximum angle of rotation of the rocker shaft 20 in the forward direction can just trigger the micro switch 30 corresponding to that direction. However, if the rocker shaft 20 rotates to its maximum angle in the oblique direction, it cannot trigger the two micro switches 30 corresponding to that oblique direction. Conversely, if the diameter of the limiting hole 401 is large, and the maximum angle of rotation of the rocker shaft 20 in the oblique direction can just trigger the two micro switches 30 corresponding to that direction, when the rocker shaft 20 rotates to that maximum angle in the forward direction, the distance that the trigger 21 moves after pressing against the micro switch 30 exceeds the designed stroke of the micro switch 30, which may damage the micro switch 30.

[0040] Combination Figure 9 On the horizontal projection, a rectangle is drawn with the four microswitches 30 as its sides. The center of the trigger 21 is initially located at the center O of this rectangle (the dotted circle in the figure represents the initial position of the trigger 21). The center O of this rectangle is also the position of the axis when the rocker shaft 20 is in the centered state. The height H from the center O of the trigger 21 to the rotation center of the rocker shaft 20 is the height of the height of the rocker shaft 20. When the rocker shaft 20 rotates forward to the position that triggers the microswitches 30, the center of the trigger 21 moves to position C1, and the corresponding positive rotation angle θ1 of the rocker shaft 20 is given. L1 is the distance from point O to C1. When the rocker shaft 20 rotates to the right front to the position that triggers the two microswitches 30 in front and to the right, the center of the trigger 21 moves to position C2, and the corresponding oblique rotation angle θ2 of the rocker shaft 20 is given. L2 is the distance from point O to C2, and the angle between L1 and L2 is A. Ideally, the parameters satisfy: L1=H*tanθ1, L2=H*tanθ2, L1=L2*cosA.

[0041] Generally, the line connecting the four microswitches 30 forms a square, and the angle between L1 and L2 is A = 45 degrees. Further derivation shows that: tanθ1 = tanθ2 * cos45.

[0042] Under the aforementioned conditions, the joystick will not damage the microswitch 30 in the forward direction when performing diagonal control operations.

[0043] Considering that the micro switch 30 has a certain trigger stroke range (in this embodiment, the trigger stroke of the micro switch 30 is 1.5-2.5mm), Figure 9 The dashed line of the rectangle indicates the position of the key shaft 32 when the micro switch 30 is triggered. Considering the influence of the size of the trigger element 21 on the rotation angle of the rocker shaft 20, after multiple experiments, the above relationship is corrected as follows: tanθ1=K*tanθ2, 0.67≤K<1.

[0044] It should be noted that, with the positions and dimensions of the trigger 21 and the micro switch 30 fixed, the control of the aforementioned maximum rotation angle is achieved through the limiting hole 401 of the retaining ring 40. The size and shape of the limiting hole 401, and its cooperation with the limiting member 25, ensure that the rotation of the rocker shaft 20 meets the aforementioned conditions.

[0045] The distance between the wall of the limiting hole 401 and the center is different in the forward and oblique directions. It can be understood that the distance B1 from the hole wall to the rotation axis of the rocker shaft 20 in the forward direction and the distance B2 from the contact point of the trigger 21 and the micro switch 30 to the rotation axis of the rocker shaft 20 are linearly related. This relationship is obtained by converting it with the height of the rotation center, which will not be discussed in detail here.

[0046] Figure 4 In the structure shown, the limiting hole 401 is a chamfered rectangle, so that the distance from the center of the limiting hole 401 to the wall of the hole in the oblique direction is greater than the distance from it to the wall of the hole in the normal direction. Figure 5 In the structure shown, the limiting hole 401 is approximately circular, and its length in the forward direction is less than its length in the oblique direction. Those skilled in the art can determine the shape and size of the limiting hole 401 according to the above-mentioned angle, but no single limitation is made here.

[0047] The wall of the limiting hole 401 is inclined so that when the limiting member 25 abuts against the retaining ring 40, the limiting member 25 and the wall of the limiting hole 401 are in surface contact. Preferably, the inclination angle of the wall of the limiting hole 401 in the forward and inclined directions corresponds to the rotation angle of the rocker shaft 20, that is, the inclination angle in the forward direction is θ1 and the inclination angle in the inclined direction is θ2. The wall of the limiting hole 401 has an arc transition from the forward to the inclined direction to ensure the smooth operation of the rocker shaft 20 moving from the forward to the inclined direction.

[0048] Therefore, the joystick provided in this embodiment, as well as the handle and arcade machine using this joystick, uses a mechanical shaft push-button switch instead of the existing spring-loaded microswitch 30 for the joystick's microswitch 30, which can effectively reduce the joystick's noise and improve its lifespan. By limiting the rotation angle of the joystick shaft 20, eight-directional output control can be achieved, ensuring that the microswitch 30 in the forward direction will not be damaged when the joystick is used for diagonal control operations.

[0049] In another embodiment of this application, the joystick satisfies the following: the forward rotation angle θ1 is less than the oblique rotation angle θ2, the forward rotation angle θ1 is 7.5°-9°, and the oblique rotation angle θ2 is 8.1°-11°.

[0050] Those skilled in the art can set the forward rotation angle θ1 to 7.5°, 7.6°, 7.65°, 7.7°, 7.8°, 8.0°, 8.1°, 8.2°, 8.3°, 8.4°, 8.45°, 8.5°, 8.6°, 8.8°, 8.9°, 9.0°, etc., depending on the actual situation. The oblique rotation angle θ2, while satisfying that it is greater than the forward rotation angle θ1, can be selected as 8.1°, 8.5°, 8.6°, 8.65°, 8.7°, 8.8°, 9.0°, 9.2°, 9.3°, 9.4°, 9.6°, 9.8°, 10.0°, 10.2°, 10.3°, 10.5°, 10.6°, 10.8°, 10.85°, 10.9°, 11.0°, etc.

[0051] In another embodiment of this application, the trigger 21 is cylindrical, and the gap S between its outer surface and the key shaft 32 is in the range of 0-0.8 mm. It should be noted that this dimension is based on the measurement when the rocker shaft 20 is in the centered state. With the position of the micro switch 30 fixed, the larger the diameter of the trigger 21, the smaller the angle θ1 that the trigger 21 rotates from the centered state (point O) to the state of triggering the micro switch 30, and the shorter the distance moved from the forward to the oblique direction (the distance C1-C2), making the rocker arm more sensitive to control. If the gap is too small, it is easy to cause misoperation due to small disturbances in the rocker arm; therefore, the diameter of the trigger 21 needs to be controlled within a certain range. After multiple experiments, the rocker arm has good control performance when the gap S between the trigger 21 and the key shaft 32 is in the range of 0-0.8 mm. The gap between the trigger 21 and the key shaft 32 is further preferably in the range of 0.1-0.3 mm. Those skilled in the art can adjust the gap between the trigger element 21 and the key shaft 32 by adjusting the position of the micro switch 30 or adjusting the diameter of the trigger element 21. The gap S between the trigger element 21 and the key shaft 32 can be set to 0.1mm, 0.11mm, 0.12mm, 0.13mm, 0.14mm, 0.15mm, 0.16mm, 0.18mm, 0.2mm, 0.22mm, 0.23mm, 0.24mm, 0.25mm, 0.26mm, 0.27mm, 0.28mm, 0.29mm, or 0.3mm.

[0052] In another embodiment of this application, the trigger 21 is cylindrical and satisfies: , Where r is the radius of the trigger 21, and B is the distance from the surface of the key shaft 32 facing the trigger 21 to the center of the rocker shaft 20.

[0053] In light of the foregoing, the diameter of the trigger element 21 affects the control sensitivity of the joystick. Through multiple experiments, a ratio between the radius r of the trigger element 21 and the distance B from the key shaft 32 to the center of the joystick shaft 20 is found to achieve good control performance within the range of 0.95-1. Those skilled in the art can specifically set this ratio to 0.95, 0.952, 0.955, 0.96, 0.965, 0.97, 0.978, 0.98, 0.982, 0.986, 0.99, 0.995, 1.0, etc., and no single limitation is made here.

[0054] In this embodiment, the radius of the trigger element 21 is 7.7-7.9 mm, and the distance B from the surface of the key shaft 32 facing the trigger element 21 to the center of the rocker shaft 20 is 7.9-8.1 mm. The trigger stroke of the micro switch 30 is 1.2-1.5 mm, and the maximum stroke is 3.5 mm.

[0055] In another embodiment of this application, please refer to Figures 5 to 8 The fixed base 31 is provided with a fixed strip 33, and the base 10 is provided with a fixed groove 101 that cooperates with the fixed strip 33.

[0056] The micro switch 30 is small in size, and its projection onto the four adjacent sides of the key shaft 32 is roughly rectangular, making its fixation relatively difficult. In this embodiment, the mounting base 31 is provided with a fixing strip 33, which is annular and surrounds the four adjacent sides of the key shaft 32. It should be noted that the fixing strip 33 is a conventional design of the micro switch 30. Using the fixing strip 33 as a connection point, a fixing groove 101 matching the fixing strip 33 is provided on the base 10. The fixing strip 33 inserts into the fixing groove 101, achieving a fixed assembly of the micro switch 30 and simplifying the structure. The fixing strip 33 is located on the side of the base body 311 and is inserted into the fixing groove 101.

[0057] In another embodiment of this application, please refer to Figure 5 The base 10 includes a base plate 11 and a fixing member 12 connecting the base plate 11. There are four fixing members 12 and they are arranged corresponding to the micro switch 30. The fixing member 12 includes a first baffle 121 and a second baffle 122 located on both sides of the micro switch 30. The first baffle 121 and the second baffle 122 are both provided with fixing grooves 101.

[0058] It is understood that the first baffle 121 and the second baffle 122 are located on both sides of the micro switch 30 on the key shaft 32, and the first baffle 121 and the second baffle 122 serve as the carriers of the fixing groove 101. In this embodiment, the substrate 11 is placed horizontally, the first baffle 121 and the second baffle 122 are perpendicular to the substrate 11, and the extension direction of the fixing groove 101 is also perpendicular to the substrate 11. During assembly, the substrate 11 is flat, and the fixing member 12 is located above the carrier plate. By aligning the fixing strips 33 on both sides of the base body with the two fixing grooves 101 of the fixing member 12 and inserting them downward into the corresponding fixing grooves 101, the micro switch 30 can be fixed, which is very convenient to operate.

[0059] In another embodiment of this application, please refer to Figure 2 and Figure 6 The micro switch 30 is electrically connected to the circuit board 50 via a conductive sheet 51. In other embodiments, the micro switch 30 can also be electrically connected to the circuit board 50 via a wire, or the pins of the micro switch 30 can be directly soldered to the circuit board 50.

[0060] In this embodiment, please refer to Figure 6 The conductive sheet 51 has a insertion slot at the end opposite to the circuit board 50. When the fixing strip 33 is inserted into the insertion slot, the pins of the micro switch 30 are placed into the insertion slot. Figure 5The circuit board 50 is placed horizontally on the side of the substrate 11 opposite to the micro switch 30, at the bottom in the viewing direction. A conductive sheet 51 connects to the circuit board 50 and extends upwards, with a socket groove at its upper end. The pins of the micro switch 30 extend horizontally and into the socket groove. Electrical connection between the pins of the micro switch 30 and the conductive sheet 51 can be achieved through contact between the pins and the socket groove, or through soldering. Preferably, the pins and the conductive sheet 51 are soldered together to ensure a secure connection and reduce the risk of the pins separating from the conductive sheet 51 due to vibration caused by the rocker shaft 20 pressing against the micro switch 30. The pins of the micro switch 30 are parallel to the circuit board 50, and the two ends of the conductive sheet 51 connect the pins and the circuit board 50, a reasonable design that simplifies the structure. The conductive sheet 51 connects to the pins of the micro switch 30 through the socket groove, simplifying assembly and facilitating subsequent soldering operations.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
