Description

Technical Field

[0001] This application belongs to the field of automation equipment technology, and in particular relates to a position-adjustable platform structure suitable for automation equipment. Background Technology

[0002] Currently, in automated production equipment, a support platform is typically used at the processing position to support the materials to be processed. When the materials to be processed are relatively small, the support platform is generally also relatively small in size to enable high-speed operation. Most of these small support platforms do not have adjustable components designed to adjust the height of the support platform.

[0003] The aforementioned small-volume support platform is typically mounted on a mobile base using multiple screws. If, after installation, the support surface of the support platform is found to be skewed relative to the working surface, the support surface is usually adjusted by adding or removing shims at the screw mounting points. This process is cumbersome, labor-intensive, and time-consuming. Utility Model Content

[0004] The purpose of this application is to provide a position-adjustable platform structure to solve the problems of cumbersome operation and time-consuming labor when adjusting the bearing surface of the existing bearing platform.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] An adjustable platform structure includes a base, a support platform, and at least two sets of connecting components, wherein...

[0007] The carrying platform is configured to carry materials.

[0008] At least two sets of connecting components are configured to fix the support platform to the base, at least two sets of connecting components are configured to be symmetrically distributed relative to the support platform, and each set of connecting components is also configured to adjust the height of the position of the support platform where the set of connecting components is located relative to the base.

[0009] By symmetrically setting at least two sets of connecting components between the base and the bearing platform, the relative fixation between the bearing platform and the base is achieved. At the same time, the height of the bearing platform relative to the base at the position of each connecting component can be adjusted, thereby adjusting the levelness of the bearing platform. This is convenient, time-saving, and labor-saving.

[0010] Optionally, each connection assembly includes a support member, a first locking assembly, and a second locking assembly, wherein,

[0011] The support member is adjustable in height and mounted on the base; the support member is configured to support the load-bearing platform.

[0012] The first locking assembly is configured to lock or release the support relative to the base, such that the support is in a locked state and a released state. The first end of the second locking assembly is connected to the support, and the second end of the second locking assembly is connected to the bearing platform. The second locking assembly is configured to lock or release the bearing platform relative to the support.

[0013] With the support in the loosened state, adjust the height of the support relative to the base to adjust the levelness of the load-bearing platform.

[0014] The cooperation of the support member, the first locking assembly, and the base enables the support member to be locked or released relative to the base, thereby allowing the support member to be adjusted in height relative to the base. The cooperation of the support member, the second locking assembly, and the bearing platform enables the bearing platform and the support member to be connected as one unit, ensuring that the position of the bearing platform relative to the support member does not change when the height of the support member is adjusted, thereby improving the adjustment accuracy of the level of the bearing platform.

[0015] Optionally, the support includes a first adjusting screw sleeve, which has an external thread and an internal through hole. The base has a first threaded hole, and the first adjusting screw sleeve is screwed to the base through the engagement of the external thread and the first threaded hole.

[0016] The second locking assembly includes a first bolt, a threaded groove is provided on the bearing platform, the shank of the first bolt passes through the inner through hole of the first adjusting sleeve from bottom to top and is screwed into the threaded groove on the bearing platform, and the first adjusting sleeve protrudes from the base to support the bearing platform;

[0017] A first tensioning assembly is provided between the first bolt and the first adjusting sleeve. The first tensioning assembly is configured to provide tension force to keep the load-bearing platform and the support in a taut state at all times.

[0018] With the support member in the loosened state, rotate the first adjusting sleeve to raise or lower it relative to the base, thereby raising or lowering the bearing platform to adjust the level of the bearing platform.

[0019] By screwing the first adjusting sleeve onto the base, the relative lifting of the first adjusting sleeve to the base is achieved; by cooperating with the first bolt, the first adjusting sleeve, and the bearing platform, the first adjusting sleeve and the bearing platform can be locked or loosened; by setting the first tensioning component, it is ensured that the position of the bearing platform relative to the support will not change after the first bolt is locked; a support with a simple structure, small footprint, and easy adjustment is provided.

[0020] Optionally, the first tensioning assembly includes a first elastic element, which is sleeved on the first bolt. The first end of the first elastic element abuts against the head protrusion at the lower end of the first bolt, and the second end of the first elastic element abuts against the first adjusting sleeve.

[0021] The elastic force provided by the first elastic element ensures that the load-bearing platform and the support are always in a tensioned state; this provides a first tensioning component that is simple in structure, easy to implement, and low in cost.

[0022] Optionally, a threaded sleeve is screwed into the threaded groove, and the shank of the first bolt is screwed into the internal threaded hole of the threaded sleeve.

[0023] By screwing a threaded sleeve into the threaded groove and screwing the first bolt into the threaded sleeve, the bearing platform can be protected, avoiding direct threaded connection between the bearing platform and the first bolt, which would reduce the movement accuracy and damage the threads after long-term operation.

[0024] Optionally, the first locking assembly includes a pressure block and at least two tightening screws. The side of the pressure block has a first semi-threaded hole in the vertical direction, and the side of the base has a second semi-threaded hole in the vertical direction. The first semi-threaded hole and the second semi-threaded hole are closed to form a first threaded hole. The at least two tightening screws pass through the pressure block in the second direction and are threadedly connected to the base to install the pressure block on the base in a tight or loose manner.

[0025] When the pressure block is tightly installed on the base, the friction between the first adjusting screw sleeve and the first threaded hole increases, so that the first adjusting screw sleeve is fixed relative to the base;

[0026] When the pressure block is loosened and installed on the base, there is a gap between the pressure block and the base so that the first adjusting sleeve can rotate within the first threaded hole.

[0027] By using the pressure block and at least two tightening screws, the friction between the first adjusting sleeve and the first threaded hole can be increased or decreased, thereby enabling the pressure block to be installed on the base tightly or loosely. This provides a first locking assembly that is simple in structure, easy to process, and low in cost. At the same time, the pressure block and the base are designed as separate structures, which facilitates the maintenance and replacement of parts in the later stages and helps to reduce the cost of use.

[0028] Optionally, the support includes a second adjusting screw sleeve, which has an external thread and an internal thread hole. A third thread hole is provided on the base. The second adjusting screw sleeve is screwed to the base through the engagement of the external thread and the third thread hole. The second locking assembly includes a second bolt. A first stepped hole is provided on the bearing platform. The shank of the second bolt passes through the first stepped hole from top to bottom and is screwed into the internal thread hole. The end face of the second adjusting screw sleeve protrudes from the base to support the bearing platform.

[0029] With the support in the loosened state, rotate the second adjusting sleeve to raise or lower it relative to the base, thereby raising or lowering the bearing platform to adjust its levelness.

[0030] By screwing the second adjusting sleeve onto the base, the relative lifting and lowering of the second adjusting sleeve to the base is achieved; the cooperation of the second bolt, the first adjusting sleeve, and the bearing platform enables the locking or loosening of the second adjusting sleeve and the bearing platform; simultaneously, by passing the second bolt from top to bottom through the bearing platform and then screwing it into the internal thread hole of the second adjusting sleeve, the second bolt can be directly controlled from the bearing platform, facilitating the locking and loosening of the second bolt; this provides a support component with a simple structure, small footprint, and easy adjustment.

[0031] Optionally, a deformation gap extending along a first direction is provided on the base for each connecting assembly. The deformation gap communicates with the corresponding third threaded hole. The first locking assembly includes at least one tightening screw, which passes through the deformation gap along a second direction and is screwed onto the base. The second direction is perpendicular to the first direction.

[0032] With the support in the locked state, at least one tightening screw is configured to provide a compressive force in the second direction that reduces the deformation gap, thereby fixing the second adjusting sleeve relative to the base.

[0033] With the support member in the loosened state, at least one tightening screw releases the compressive force on the deformation gap, allowing the second adjusting sleeve to rise and fall relative to the base.

[0034] By cooperating with the deformation gap and at least one tightening screw, the friction between the second adjusting sleeve and the third threaded hole can be increased or decreased, thereby enabling the second adjusting sleeve to be locked or loosened on the base. This provides a first locking component that is simple in structure, easy to implement, and highly reliable. At the same time, the deformation gap and the base are designed as an integral structure, which is convenient for processing and can ensure processing accuracy, thereby improving the adjustment accuracy of the bearing platform.

[0035] Optionally, a protective sleeve is provided in the first stepped hole, and the protective sleeve has a second stepped hole. The shank of the second bolt passes through the second stepped hole and is screwed into the internal threaded hole. A second elastic element is provided between the head of the second bolt and the protective sleeve. The second elastic element is configured to provide tension force to keep the bearing platform and the support in a taut state. The first end of the second elastic element abuts against the head protrusion at the upper end of the second bolt, and the second end of the second elastic element abuts against the stepped surface of the second stepped hole.

[0036] By setting a protective sleeve, direct contact between the second bolt and the bearing platform is avoided, which can protect the bearing platform, extend its service life, and ensure the adjustment accuracy of the bearing platform after long-term use. The elastic force provided by the second elastic element keeps the bearing platform and the support in a taut state, ensuring that the position of the bearing platform relative to the support does not change after the second bolt is tightened.

[0037] Optionally, the end face of the support protruding from the base is set as hemispherical, and a spherical washer is embedded in the bottom surface of the bearing platform. The concave surface of the spherical washer fits the hemispherical end face of the support, and a through hole is opened on the spherical washer for the second locking component to pass through.

[0038] By matching the end faces of the spherical washer and the support, the adjustment accuracy of the load-bearing platform can be guaranteed; at the same time, direct contact between the support and the load-bearing platform is avoided, which protects the load-bearing platform and prevents wear from affecting the adjustment accuracy of the load-bearing platform.

[0053] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] Currently, in automated production equipment, a support platform is typically used at the processing position to support the materials to be processed. When the materials to be processed are relatively small, the support platform is generally also relatively small in size to enable high-speed operation. Most of these small support platforms do not have adjustable components designed to adjust the height of the support platform.

[0055] The aforementioned small-volume support platform is typically mounted on a mobile base using multiple screws. If, after installation, the support surface of the support platform is found to be skewed relative to the working surface, the support surface is usually adjusted by adding or removing shims at the screw mounting points. This process is cumbersome, labor-intensive, and time-consuming.

[0056] Therefore, this application proposes a position-adjustable platform structure, please refer to [link / reference]. Figure 1 As shown in the figure, an adjustable platform structure provided in this application embodiment includes a base 10, a support platform 20, and at least two sets of connecting components 30. The support platform 20 is configured to support materials, and the at least two sets of connecting components 30 are configured to fix the support platform 20 on the base 10. The at least two sets of connecting components 30 are configured to be symmetrically distributed relative to the support platform 20. Each set of connecting components 30 is also configured to adjust the height of the position of the set of connecting components 30 on the support platform 20 relative to the base 10.

[0057] As can be seen, by symmetrically arranging at least two sets of connecting components 30 between the base 10 and the bearing platform 20, the relative fixation between the bearing platform 20 and the base 10 is achieved. At the same time, the height of the bearing platform 20 relative to the base 10 at the position of each connecting component 30 can be adjusted, thereby achieving the adjustment of the level of the bearing platform 20. This is convenient to operate and saves time and effort.

[0058] Specifically, the connection components 30 can be configured as two, three, four, five, six or more sets, as long as they can provide balanced support for the bearing platform 20.

[0059] Please see Figure 2 and Figure 3 As shown, in one embodiment, each connecting assembly 30 includes a support member 31, a first locking assembly 32, and a second locking assembly 33. The support member 31 is adjustablely mounted on the base 10 and is configured to support the bearing platform 20. The first locking assembly 32 is configured to lock or release the support member 31 relative to the base 10, so that the support member 31 is in a locked state and a released state. The first end of the second locking assembly 33 is connected to the support member 31, and the second end of the second locking assembly 33 is connected to the bearing platform 20. The second locking assembly 33 is configured to lock or release the bearing platform 20 relative to the support member 31. When the support member 31 is in the released state, the height of the support member 31 relative to the base 10 is adjusted to adjust the levelness of the bearing platform 20.

[0060] As can be seen, through the cooperation of the support member 31, the first locking component 32 and the base 10, the support member 31 can be locked or released relative to the base 10, thereby enabling the support member 31 to be adjusted in height relative to the base 10; through the cooperation of the support member 31, the second locking component 33 and the bearing platform 20, the bearing platform 20 and the support member 31 are connected as one unit, so as to ensure that the position of the bearing platform 20 relative to the support member 31 does not change when the height of the support member 31 is adjusted, thereby improving the adjustment accuracy of the level of the bearing platform 20.

[0061] In practical applications, the support member 31, the first locking assembly 32, and the second locking assembly 33 can adopt different structural forms as needed. For specific structural details, please refer to the following embodiment:

[0062] Example 1

[0063] Please see Figures 3 to 5As shown, in one embodiment, the support member 31 includes a first adjusting screw sleeve 310, which has an external thread and an internal through hole 311. The base 10 has a first threaded hole, and the first adjusting screw sleeve 310 is screwed to the base 10 through the engagement of the external thread and the first threaded hole. The second locking assembly 33 includes a first bolt 330, and the bearing platform 20 has a threaded groove 200. The shank of the first bolt 330 passes through the internal through hole 311 of the first adjusting screw sleeve 310 from bottom to top and is screwed to the bearing platform 20. Within the threaded groove 200 on the base 10, a first adjusting sleeve 310 protrudes from the base 10 to support the bearing platform 20. A first tensioning assembly is provided between the first bolt 330 and the first adjusting sleeve 310. The first tensioning assembly is configured to provide tension force that keeps the bearing platform 20 and the support member 31 in a taut state. When the support member 31 is in a loose state, rotating the first adjusting sleeve 310 causes the first adjusting sleeve 310 to rise or fall relative to the base 10, thereby driving the bearing platform 20 to rise or fall to adjust the level of the bearing platform 20.

[0064] Specifically, the bottom of the first adjusting screw sleeve 310 is provided with an outer polygon that facilitates the rotation of the first adjusting screw sleeve 310.

[0065] Specifically, an inner polygonal opening is provided on the bottom surface of the head of the first bolt 330 at the lower end to facilitate the rotation of the first bolt 330.

[0066] As can be seen, by screwing the first adjusting sleeve 310 onto the base 10, the first adjusting sleeve 310 can be raised or lowered relative to the base 10; by cooperating with the first bolt 330, the first adjusting sleeve 310, and the bearing platform 20, the first adjusting sleeve 310 and the bearing platform 20 can be locked or loosened; by setting the first tensioning component, it is ensured that the position of the bearing platform 20 relative to the support member 31 will not change after the first bolt 330 is locked; a support member 31 with a simple structure, small space occupation, and easy adjustment is provided.

[0067] In one embodiment, the first tensioning assembly includes a first elastic element 331, which is sleeved on the first bolt 330. The first end of the first elastic element 331 abuts against the head protrusion at the lower end of the first bolt 330, and the second end of the first elastic element 331 abuts against the first adjusting sleeve 310.

[0068] It can be seen that the elastic force provided by the first elastic element 331 keeps the bearing platform 20 and the support element 31 in a taut state at all times; thus, a first tensioning component with a simple structure, easy implementation and low cost is provided.

[0069] Specifically, the bottom surface of the first adjusting screw sleeve 310 is provided with a mounting hole 312, which is a stepped hole. The first tensioning assembly also includes a first protective sleeve 332 and a first washer 333. The first protective sleeve 332 is assembled in the mounting hole 312, and the first washer 333 is installed in the mounting hole 312 on the bottom surface of the first protective sleeve 332. The second end of the first elastic member 331 abuts against the first washer 333.

[0070] It can be seen that by setting the first protective sleeve 332 and the first gasket 333, the first elastic element 331 is prevented from directly contacting the support element 31, thus protecting the support element 31.

[0071] Specifically, the first elastic element 331 may be a helical spring, multiple stacked disc springs, elastic pads, or other elastic components.

[0072] In one embodiment, a threaded sleeve 201 is threaded into the threaded groove 200, and the shank of the first bolt 330 is threaded into the internal threaded hole of the threaded sleeve 201.

[0073] It can be seen that by screwing the sleeve 201 into the threaded groove 200 and screwing the first bolt 330 into the sleeve 201, the bearing platform 20 can be protected, avoiding direct threaded connection between the bearing platform 20 and the first bolt 330, which would cause a decrease in movement accuracy and damage to the threads after long-term operation.

[0074] Please see Figure 2 and Figure 4 As shown, in one embodiment, the first locking assembly 32 includes a pressure block 320 and at least two tightening screws 321. The pressure block 320 has a first semi-threaded hole on its side along the vertical direction, and the base 10 has a second semi-threaded hole on its side along the vertical direction. The first semi-threaded hole and the second semi-threaded hole are joined to form a first threaded hole. The at least two tightening screws 321 are respectively positioned along a second direction (…). Figure 2 The first adjusting sleeve 310 (in the Y1 direction) passes through the pressure block 320 and is threadedly connected to the base 10 to install the pressure block 320 on the base 10 either close or loosely; when the pressure block 320 is installed close to the base 10, the friction between the first adjusting sleeve 310 and the first threaded hole increases, so that the first adjusting sleeve 310 is fixed relative to the base 10; when the pressure block 320 is loosely installed on the base 10, there is a gap between the pressure block 320 and the base 10, so that the first adjusting sleeve 310 can rotate in the first threaded hole.

[0075] Specifically, the first locking component 32 includes components along a first direction ( Figure 2 Two tightening screws 321 are spaced apart in the X1 direction, with the first direction perpendicular to the second direction.

[0076] It can be seen that by cooperating with the pressure block 320 and at least two tightening screws 321, the friction between the first adjusting sleeve 310 and the first threaded hole can be increased or decreased, thereby realizing the pressure block 320 being installed tightly or loosely on the base 10; a first locking component 32 with simple structure, easy to process and low cost is provided. At the same time, the pressure block 320 and the base 10 are designed as separate structures, which facilitates the maintenance and replacement of parts in the later stage and helps to reduce the cost of use.

[0077] The position-adjustable platform structure provided in this embodiment is equipped with three sets of connecting components 30 arranged in an isosceles triangle. In use, the three sets of connecting components 30 fix the bearing platform 20 on the base 10. When it is necessary to adjust the level of the bearing platform 20, first loosen the tightening screw 321 of the connecting component 30 to be adjusted, so that the first adjusting sleeve 310 can rotate in the first threaded hole. By rotating the first adjusting sleeve 310 and cooperating with the first threaded hole, the height of the first adjusting sleeve 310 is adjusted to adjust the level of the bearing platform 20. After adjustment, tighten the tightening screw 321.

[0078] Example 2

[0079] Please see Figures 6 to 9 As shown, in one embodiment, the support member 31 includes a second adjusting screw sleeve 313, which has an external thread and an internal thread hole. The base 10 has a third thread hole. The second adjusting screw sleeve 313 is screwed to the base 10 through the engagement of the external thread and the third thread hole. The second locking assembly 33 includes a second bolt 334. The bearing platform 20 has a first stepped hole 202. The shank of the second bolt 334 passes through the first stepped hole 202 from top to bottom and is screwed into the internal thread hole. The end face of the second adjusting screw sleeve 313 protrudes from the base 10 to support the bearing platform 20. When the support member 31 is in the loosened state, rotating the second adjusting screw sleeve 313 causes the second adjusting screw sleeve 313 to rise and fall relative to the base 10, thereby driving the bearing platform 20 to rise and fall to adjust the level of the bearing platform 20.

[0080] Specifically, the bottom of the second adjusting screw sleeve 313 is provided with an outer polygon that facilitates the rotation of the second adjusting screw sleeve 313.

[0081] Specifically, the head end face of the second bolt 334 is provided with an inner polygonal opening to facilitate the rotation of the second bolt 334.

[0082] As can be seen, by screwing the second adjusting sleeve 313 onto the base 10, the second adjusting sleeve 313 can be raised or lowered relative to the base 10; through the cooperation of the second bolt 334, the first adjusting sleeve 313, and the bearing platform 20, the second adjusting sleeve 313 can be locked or loosened from the bearing platform 20; at the same time, by passing the second bolt 334 from top to bottom through the bearing platform 20 and then screwing it into the internal thread hole of the second adjusting sleeve 313, the second bolt 334 can be directly controlled from the bearing platform 20, which facilitates the locking and loosening of the second bolt 334; a support member 31 with a simple structure, small space occupation, and easy adjustment is provided.

[0083] As one implementation method, the base 10 has a corresponding third-direction ( ) opening on each set of connecting components 30. Figure 7 The deformation gap 11 extends in the X2 direction and communicates with the corresponding third threaded hole. The first locking assembly 32 includes at least one tightening screw 321, which extends in the fourth direction (X2 direction). Figure 7 The second adjusting sleeve 313 passes through the deformation gap 11 and is screwed onto the base 10 in the direction of Y2. The third direction is perpendicular to the fourth direction. When the support member 31 is in the locked state, at least one tightening screw 321 is configured to provide a compressive force in the fourth direction that reduces the deformation gap 11, thereby fixing the second adjusting sleeve 313 relative to the base 10. When the support member 31 is in the loosened state, at least one tightening screw 321 removes the compressive force on the deformation gap 11, thereby allowing the second adjusting sleeve 313 to be raised and lowered relative to the base 10.

[0084] It can be seen that by cooperating with the deformation gap 11 and at least one tightening screw 321, the friction between the second adjusting sleeve 313 and the third threaded hole can be increased or decreased, thereby enabling the second adjusting sleeve 313 to be locked or loosened on the base 10; a first locking component 32 with simple structure, easy implementation and high reliability is provided. At the same time, the deformation gap 11 and the base 10 are integrated into a single structure, which is easy to process and can ensure processing accuracy, thereby improving the adjustment accuracy of the bearing platform 20.

[0085] In one embodiment, a second protective sleeve 335 is provided in the first stepped hole 202, and the second protective sleeve 335 has a second stepped hole 336. The shank of the second bolt 334 passes through the second stepped hole 336 and is screwed into the internal thread hole of the second adjusting sleeve 313. A second elastic element 337 is provided between the head of the second bolt 334 and the second protective sleeve 335. The second elastic element 337 is configured to provide tension force to keep the bearing platform 20 and the support member 31 in a taut state. The first end of the second elastic element 337 abuts against the head protrusion at the upper end of the second bolt 334, and the second end of the second elastic element 337 abuts against the stepped surface of the second stepped hole 336.

[0086] Specifically, a second washer 338 is provided on the step surface of the second step hole 336 and fitted onto the second bolt 334, and the second end of the second elastic member 337 abuts against the second washer 338.

[0087] Specifically, the second elastic element 337 may be a helical spring, multiple stacked disc springs, elastic pads, or other elastic components.

[0088] It is evident that by setting the second protective sleeve 335 and the second gasket 338, direct contact between the second bolt 334 and the bearing platform 20 is avoided, which can protect the bearing platform 20, extend its service life, and ensure the adjustment accuracy of the bearing platform 20 after long-term use. The elastic force provided by the second elastic element 337 ensures that the bearing platform 20 and the support member 31 are always in a taut state, ensuring that the position of the bearing platform 20 relative to the support member 31 does not change after the second bolt 334 is tightened.

[0089] The position-adjustable platform structure provided in this embodiment is equipped with four sets of connecting components 30 arranged in a rectangle. In use, the four sets of connecting components 30 fix the bearing platform 20 on the base 10. When it is necessary to adjust the level of the bearing platform 20, first loosen the tightening screw 321 of the connecting component 30 to be adjusted, so that the second adjusting screw sleeve 313 can rotate in the third threaded hole. Rotate the second adjusting screw sleeve 313, and adjust the height of the second adjusting screw sleeve 313 through the cooperation between the second adjusting screw sleeve 313 and the third threaded hole to adjust the level of the bearing platform 20. After the adjustment is in place, tighten the tightening screw 321.

[0090] Please see Figure 3 , Figure 5 , Figure 7 and Figure 9 As shown, it should be noted that: as one implementation method, the support member 31 in the above embodiment 1 and embodiment 2 protrudes from the end face of the base 10 and is set as a hemispherical shape. The bottom surface of the bearing platform 20 is embedded with a spherical washer 40. The concave surface of the spherical washer 40 fits the hemispherical end face of the support member 31. The spherical washer 40 is provided with a through hole for the second locking component 33 to pass through.

[0091] It can be seen that the fit between the spherical washer 40 and the end face of the support 31 can ensure the adjustment accuracy of the bearing platform 20; at the same time, it avoids direct contact between the support 31 and the bearing platform 20, thus protecting the bearing platform 20 and preventing wear from affecting the adjustment accuracy of the bearing platform 20.

[0093] 1) It enables the adjustment of the level of the support platform, which is convenient to operate, saves time and effort, and has high adjustment accuracy;

[0094] 2) The connection components have a simple overall structure, occupy little space, have low cost, and have a long service life.

[0095] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
