Description

Technical Field

[0001] The present application relates to the field of extruders, and in particular to an adjustable base of an extruder. Background Art

[0002] The extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material and form it through the die.

[0003] A traditional extruder includes a base, on which a barrel is installed, a screw is arranged in the barrel, a die is arranged at one end of the barrel, a gear box is connected to the base at the other end of the barrel, and the output shaft of the gear box is transmission connected to the screw, and a drive motor is fixedly connected to the end of the gear box away from the barrel, and the output shaft of the drive motor is transmission connected to the input shaft of the gear box.

[0004] The position of the base of the extruder for installing the barrel is often fixed. When replacing a longer barrel, the barrel will extend out of the base, affecting the stability of the barrel when the extruder is working. Summary of the invention

[0005] In order to enable the extruder base to adapt to barrels of more different specifications, the present application provides an adjustable base for the extruder.

[0006] The adjustable base of the extruder provided in this application adopts the following technical solution:

[0007] An adjustable base for an extruder comprises a base, on which a first slide for receiving a gear box and a second slide for receiving a driving motor are slidably arranged, a limiting assembly for fixing the first slide is arranged on the base, a connecting rod is hinged on the first slide, a sliding seat is slidably arranged on the second slide, the connecting rod is detachably connected to the slide, and a control assembly for controlling the movement of the slide is arranged on the second slide.

[0008] By adopting the above technical solution, when the operator needs to replace a longer barrel on the base, and the length originally reserved for the barrel on the base is insufficient, the operator releases the position limiting effect of the first slide on the base through the limit assembly. Since the first slide and the second slide are fixed by a connecting rod, the operator moves the first slide and drives the second slide to move synchronously, thereby driving the drive motor and the gear box to move synchronously, and leaving more space for installing the barrel to accommodate more barrels of different lengths. When the operator needs to replace a drive motor or gear box of different power, the operator needs to adjust the spacing between the first slide and the second slide through the control assembly to separate the drive motor from the input shaft of the gear box, which is convenient for the replacement and installation of the drive motor or the gear box.

[0009] Optionally, the limiting component includes a limiting rod hinged to the first sliding table. A support plate is fixedly connected to the base. A plurality of first limiting grooves for inserting the limiting rod are formed in the support plate at positions corresponding to the limiting rod. A limiting nut for pressing against the support plate is threadedly connected to the limiting rod.

[0010] By adopting the above technical solution, the operator pushes the first sliding table to move on the base. After the first sliding table moves to a suitable position, the operator flips the limiting rod so that the limiting rod is clamped in the corresponding first limiting groove. Then, the operator tightens the limiting nut so that the limiting nut presses against the support plate, realizing the position fixation of the first sliding table on the base.

[0011] Optionally, a second limiting groove for inserting the limiting rod is formed in the first sliding table. An insertion cylinder is fixedly connected to the limiting nut. The insertion cylinder is sleeved on the limiting rod. First through holes for inserting the insertion cylinder are formed in the support plate at positions corresponding to each of the first limiting grooves. The diameter of the first through hole is larger than the width of the first limiting groove. A second through hole for inserting the insertion cylinder is formed in the first sliding table at a position corresponding to the second limiting groove. The diameter of the second through hole is larger than the width of the second limiting groove.

[0012] By adopting the above technical solution, after the operator moves the first sliding table to a suitable position, the second limiting groove is aligned with the first limiting groove at the corresponding position, and the second through hole is aligned with the corresponding first through hole. The operator flips the limiting rod into the second limiting groove and the first limiting groove at the corresponding position. Then, the operator turns the limiting nut so that the limiting nut pushes the insertion cylinder into the first through hole and the second through hole. By providing the insertion cylinder, on the one hand, it restricts the limiting rod from disengaging from the first through hole and the second through hole; on the other hand, the insertion cylinder bears the shear force between the first through hole and the second through hole, reducing the deformation of the limiting rod due to force.

[0013] Optionally, the control component includes a first screw rod rotatably connected to the second sliding table. A connecting plate is fixedly connected to the sliding seat. The first screw rod penetrates through the connecting plate and is threadedly connected to the connecting plate.

[0014] By adopting the above technical solution, the operator rotates the first screw rod to adjust the position of the sliding seat on the second sliding table, thereby adjusting the distance between the first sliding table and the second sliding table to facilitate the installation and disassembly of the driving motor and the gearbox.

[0015] Optionally, a first rack is fixedly connected to the connecting rod, a second rack for cooperating with the first rack is fixedly connected to the sliding seat, a slider is slidably arranged on the second sliding table, a pressing plate is fixedly connected to the slider, a first inclined surface is arranged on one side of the pressing plate facing the connecting rod, and the first inclined surface inclines away from the slider on the side facing the first sliding table. A second inclined surface cooperating with the first inclined surface is arranged on the connecting rod. A locking rod is hinged to the pressing plate, a vertical plate is fixedly connected to the connecting rod, a locking groove for the locking rod to pass through is formed in the vertical plate, and a locking nut for pressing against the vertical plate is threadedly connected to the locking rod.

[0016] By adopting the above technical solution, during the fixing process of the first sliding table and the second sliding table, the operator adjusts the distance between the first sliding table and the second sliding table, then the operator flips the connecting rod to make the first rack on the connecting rod cooperate with the second rack on the sliding seat, then the operator slides the slider to press the first inclined surface against the second inclined surface, so that the first rack is pressed against the second rack. The operator flips the locking rod to insert the locking rod into the locking groove, and finally the operator turns the locking nut to press the locking nut against the vertical plate to fix the position between the first sliding table and the second sliding table. The operator can fine-tune the position distance between the first sliding table and the second sliding table by rotating the first stud.

[0017] Optionally, a lifting platform is slidably arranged vertically on the second sliding table. The driving motor is fixedly connected to the lifting platform through a mounting bracket. An adjusting unit for finely adjusting the position of the mounting bracket is arranged on the lifting platform. A lifter for driving the lifting platform to lift is arranged on the second sliding seat, and a control motor for driving the input shaft of the lifter to rotate is arranged on the second sliding table.

[0018] By adopting the above technical solution, the operator starts the control motor to drive the lifting platform to lift and adjusts the position of the mounting bracket through the adjusting unit so that the output shaft of the driving motor is aligned with the input shaft of the gearbox to adapt to more driving motors and gearboxes of different specifications.

[0019] Optionally, the adjusting unit includes two second studs rotatably connected to the lifting platform. The two second studs are parallel to each other. Two moving seats are slidably arranged on the lifting platform along the axial direction of the second studs. The moving seats correspond to the second studs one by one. The second studs penetrate through the corresponding moving seats and are threadedly connected to the corresponding moving seats. Ear plates are fixedly connected to both of the two moving seats. A sleeve rod is hinged to one of the ear plates. An inner rod is slidably inserted into the sleeve rod. The inner rod is hinged to the other ear plate. The mounting bracket is fixed to the sleeve rod.

[0020] By adopting the above technical solution, the operator rotates the two second studs respectively to adjust the positions of the two ear plates, and further adjusts the horizontal angle and position of the sleeve rod, so as to adjust the horizontal angle and position of the driving motor.

[0021] Optionally, a turning plate is hinged on the mounting frame, a pushing block for pushing the turning plate is slidably arranged on the mounting frame, a third stud is rotatably connected to the mounting frame, and the axial direction of the third stud is parallel to the sliding direction of the pushing block. The third stud penetrates through the pushing block and is threadedly connected to the pushing block.

[0022] By adopting the above technical solution, the operator rotates the third stud to drive the pushing block to move, and the pushing block pushes the turning plate, thereby adjusting the angle of the turning plate and realizing the adjustment of the inclination angle of the driving motor in the vertical plane.

[0023] Optionally, a wing plate is hinged on the turning plate, a limiting wheel is rotatably connected to one end of the wing plate away from the turning plate, a limiting block is arranged on the pushing block, and a third inclined surface for the limiting wheel to abut against is arranged on the lower surface of the limiting block, so that the side of the third inclined surface close to the pushing block inclines towards the mounting frame. A rotating seat is hinged on the turning plate, a control rod is rotatably connected to the rotating seat, and a screw sleeve is hinged on the wing plate. The control rod is threadedly connected to the screw sleeve.

[0024] By adopting the above technical solution, the operator drives the wing plate to turn by rotating the control rod, and further drives the limiting wheel to turn, so that the limiting wheel abuts against the third inclined surface, thereby restricting the upward turning of the turning plate, improving the stability of the turning plate on the mounting frame, and further improving the mounting stability of the driving motor on the second sliding table.

[0025] Optionally, a base is slidably arranged on the turning plate, the pressing plate and the control rod are both hinged on the base, a column is fixedly connected to the limiting block, and a long hole for the column to pass through is arranged on the base. The length direction of the long hole is perpendicular to the sliding direction of the base.

[0026] By adopting the above technical solution, the column is inserted into the long hole, so that the movement of the pushing block can drive the base to move synchronously, and the limiting wheel can directly turn and abut against the third inclined surface.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0039] The following is further detailed description of this application in combination with the Figures 1-8 accompanying drawings.

[0040] The embodiment of this application discloses an adjustable base for an extruder. As Figure 1 , the adjustable base for the extruder includes a rectangular base 1. The barrel 11 for installing the extruder is arranged on the base 1. A gearbox 12 and a driving motor 13 are arranged at one end of the upper surface of the base 1. The output shaft of the driving motor 13 is in transmission connection with the input shaft of the gearbox 12, and the output shaft of the gearbox 12 is in transmission connection with the screw in the barrel 11. Support bases 14 are fixedly connected to both sides of the base 1 along its width direction. Slide rails 15 are fixedly connected to the upper surfaces of the two support bases 14, and the length directions of the two slide rails 15 are parallel to the length direction of the base 1. A first slide table 16 and a second slide table 17 are arranged above the base 1. The first slide table 16 and the second slide table 17 are both slidably arranged on the two slide rails 15, and the first slide table 16 and the second slide table 17 are arranged at intervals along the length direction of the base 1. The gearbox 12 is installed on the upper surface of the first slide table 16, and the driving motor 13 is installed on the upper surface of the second slide table 17.

[0041] As Figure 2The first slide 16 is provided with a limit assembly 2 for preventing itself from sliding on the two guide rails 74 on both sides along the width direction of the base 1. The limit assembly 2 includes a horizontal plate 21 fixedly connected to the upper end of the side wall of the first slide 16. A limit rod 22 is hinged on the horizontal plate 21 through a first rotating shaft, and the axial direction of the first rotating shaft is parallel to the length direction of the base 1. A second limit groove 23 for inserting the limit rod 22 is provided on the horizontal plate 21. The second limit groove 23 is open on the side away from the first slide 16. The horizontal plate 21 is provided with a second through hole 24 at one end away from the opening of the second limit groove 23, and the diameter of the second through hole 24 is greater than the groove width of the second limit groove 23.

[0042] A rectangular support plate 25 is fixedly connected to the side of the support seat 14 facing away from the base 1, and the length direction of the support plate 25 is parallel to the length direction of the base 1. The support plate 25 is provided with a plurality of first limiting grooves 26 for inserting the limiting rods 22. The plurality of first limiting grooves 26 are evenly arranged along the length direction of the support plate 25, and the side of each first limiting groove 26 facing away from the base 1 is open. The support plate 25 is provided with a first through hole 27 corresponding to each first limiting groove 26, and the diameter of each first through hole 27 is greater than the groove width of the first limiting groove 26.

[0043] A limiting nut 28 for contacting the lower surface of the support plate 25 is threadedly connected to the limiting rod 22, and an insert 29 is coaxially fixedly connected to one end of the limiting nut 28 facing the first rotating shaft, and the insert 29 is sleeved on the limiting rod 22. The diameter of the first through hole 27 is the same as the diameter of the second through hole 24, and the outer diameter of the insert 29 is the same. When the operator moves the first slide 16 to a suitable position, the second limiting groove 23 is aligned with the first limiting groove 26 at the corresponding position, and the second through hole 24 is aligned with the first through hole 27 at the corresponding position. The operator flips the limit rod 22 so that the limit rod 22 is inserted into the first limit groove 26 and the second limit groove 23, and the insert 29 is aligned with the first through hole 27 and the second through hole 24. The operator screws the limit nut 28 so that the limit nut 28 inserts the insert 29 into the first through hole 27 and the second through hole 24, and the limit nut 28 is pressed against the lower surface of the support plate 25, so that the position of the first slide 16 is fixed on the base 1. The insert 29 is inserted into the first through hole 27 and the second through hole 24, so that the limit rod 22 is limited from being separated from the first through hole 27 and the second through hole 24, and the insert 29 bears the shear force between the support plate 25 and the cross plate 21, so as to reduce the deformation of the limit rod 22 caused by excessive force. The provision of the insert 29 is conducive to improving the stability of the first slide 16 when it is fixed on the base 1.

[0044] like Figure 1 and Figure 3, the first slide 16 is hinged with connecting rods 3 through second rotating shafts on both sides along the width direction of the base 1, and the axial directions of the two second rotating shafts are parallel to the height direction of the base 1. The second slide 17 is slidably provided with slides 31 on both sides along the width direction of the base 1, and the connecting rods 3 are detachably connected to the corresponding slides 31. The sliding directions of the two slides 31 are parallel to the sliding direction of the second slide 17, and the two slides 31 are fixedly connected by a connecting plate 34. A control component 32 for controlling the movement of the slide 31 is provided on the second slide 17, and the control component 32 includes a first stud 33 rotatably connected to the second slide 17, and the axial direction of the first stud 33 is parallel to the moving direction of the second slide 17. The first stud 33 passes through the connecting plate 34 and is threadedly connected to the connecting plate 34. The operator adjusts the position of the slide 31 on the second slide 17 by rotating the first stud 33.

[0045] like Figure 3 and Figure 4 , a first rack 4 is fixedly connected to the side of the connecting rod 3 facing the corresponding slide 31, and a second rack 41 for cooperating with the first rack 4 is fixedly connected to the slide 31. Slide blocks 42 are slidably provided on both sides of the second slide 17 along the width direction of the base 1, and the sliding direction of the slide block 42 is parallel to the sliding direction of the second slide 17. A pressing plate 43 is fixedly connected to the slider 42, and the pressing plate 43 is spaced apart from the slide 31. A first inclined surface 44 is provided on the side of the pressing plate 43 facing the first slide 16, and the first inclined surface 44 is inclined in a direction away from the slide 31 on the side of the connecting rod 3 away from the first rack 4. A second inclined surface 45 for cooperating with the first inclined surface 44 is provided on the side of the connecting rod 3 away from the first rack 4. A locking rod 47 is hinged on the pressing plate 43 through a third rotating shaft, and the axial direction of the third rotating shaft is parallel to the height direction of the base 1. A vertical plate 46 is fixedly connected to the side of the connecting rod 3 away from the first rack 4 , and a locking groove 48 for inserting a locking rod 47 is formed on the side of the vertical plate 46 away from the connecting rod 3 . A locking nut 49 is threadedly connected to the locking rod 47 for tightening the vertical plate 46 .

[0046] The operator flips the connecting rod 3 toward the corresponding slide seat 31 so that the first rack 4 and the second rack 41 are engaged with each other. Then the operator moves the slider 42 so that the end of the connecting rod 3 away from the first slide 16 can be inserted into the gap between the pressure plate 43 and the slider 42, and the first inclined surface 44 abuts against the second inclined surface 45. The operator flips the locking rod 47 so that the locking rod 47 is inserted into the locking groove 48. Finally, the operator tightens the locking nut 49 so that the locking nut 49 is pressed against the vertical plate 46. The first inclined surface 44 applies a force toward the slide seat 31 to the second inclined surface 45, so that the first rack 4 is pressed against the second rack 41, maintaining the mating stability of the first rack 4 and the second rack 41, thereby improving the connection stability between the first slide 16 and the second slide 17.

[0047] As Figure 1 and Figure 3 As shown in Figure 1 and Figure 3 , a lifting platform 5 is slidably arranged vertically on the upper surface of the second sliding table 17. A lifter 51 for controlling the lifting of the lifting platform 5 is fixedly connected to the second sliding table 17. The lifter 51 is a screw lifter 51. A control motor 52 is fixedly connected to the second sliding table 17, and the output shaft of the control motor 52 is fixedly connected coaxially with the input shaft of the lifter 51. An installation frame 53 for fixing the driving motor 13 is arranged on the lifting platform 5. An adjusting unit 6 for adjusting the horizontal position and angle of the installation frame 53 is arranged on the lifting platform 5.

[0048] As Figure 5 As shown in Figure 5 , the adjusting unit 6 includes two second studs 61 rotatably connected to the upper surface of the lifting platform 5. The axial directions of the two second studs 61 are parallel to the width direction of the base 1. The two second studs 61 are arranged at intervals along the length direction of the base 1 on the lifting platform 5, and the installation frame 53 is located between the two second studs 61. Moving seats 62 are slidably arranged on the upper surface of the lifting platform 5 corresponding to the positions of the two second studs 61. The sliding directions of the two moving seats 62 are parallel to the axial direction of the second studs 61. The second studs 61 penetrate through the corresponding moving seats 62 and are threadedly connected to the corresponding moving seats 62. Ear plates 63 are fixedly connected to both of the two moving seats 62. One of the ear plates 63 is hinged with a sleeve rod 65 through a fourth rotating shaft, and the other ear plate 63 is hinged with an inner rod 66 through a fifth rotating shaft. The axial directions of the fourth rotating shaft and the fifth rotating shaft are both parallel to the height direction of the base 1. The sleeve rod 65 and the inner rod 66 are parallel to each other, and the inner rod 66 is slidably inserted into the sleeve rod 65 along its own axis direction. The operator rotates the two second studs 61 to adjust the horizontal position and horizontal angle of the sleeve rod 65, and further adjusts the horizontal position and angle of the mounting seat and the driving motor 13.

[0049] As Figure 5 and Figure 6, the mounting bracket 53 is fixedly connected above the sleeve rod 65. The upper surface of the mounting bracket 53 is hinged with a rectangular turning plate 7 through a sixth rotating shaft. The length direction of the turning plate 7 is parallel to the axial direction of the sixth rotating shaft, and the axial direction of the sixth rotating shaft is parallel to the width direction of the base 1. The driving motor 13 is fixedly connected to the upper surface of the turning plate 7. A pushing block 72 is slidably arranged on the upper surface of the mounting bracket 53 along the length direction of the base 1. A third stud 71 is rotatably connected to the upper surface of the mounting bracket 53, and the axial direction of the third stud 71 is parallel to the moving direction of the pushing block 72. The third stud 71 penetrates through the pushing block 72 and is threadedly connected to the pushing block 72. A plurality of rollers 73 are rotatably connected to the upper surface of the pushing block 72, and the plurality of rollers 73 are coaxially arranged. A guide rail 74 is fixedly connected to the side of the turning plate 7 facing the mounting bracket 53. The length direction of the guide rail 74 is parallel to the width direction of the turning plate 7, and a fourth inclined surface 75 for the rollers 73 to abut against is arranged on the guide rail 74, and the side of the fourth inclined surface 75 away from the sixth rotating shaft is inclined towards the turning plate 7. The operator adjusts the distance between the pushing block 72 and the sixth rotating shaft by rotating the third stud 71, thereby realizing the vertical angle adjustment of the turning plate 7, and further adjusting the vertical angle of the driving motor 13.

[0050] As Figure 7 and Figure 8 , pedestals 8 are slidably arranged on both sides of the turning plate 7 along its own length direction. The sliding direction of the pedestals 8 is parallel to the width direction of the turning plate 7. A column 81 is fixedly connected to the pushing block 72 corresponding to the position of the pedestal 8. A long hole 82 for the column 81 to be inserted into is formed in the pedestal 8. The length direction of the long hole 82 is perpendicular to the upper surface of the turning plate 7, and the lower end of the long hole 82 is open. The column 81 is inserted into the long hole 82, so that the pedestal 8 can move synchronously with the pushing block 72.

[0051] The upper end of the pedestal 8 is hinged with a wing plate 83 through a seventh rotating shaft. The axial direction of the seventh rotating shaft is parallel to the width direction of the turning plate 7. A limiting wheel 84 is rotatably connected to the end of the wing plate 83 away from the pedestal 8, and the axial direction of the limiting wheel 84 is perpendicular to the sliding direction of the pedestal 8. A rotating seat 85 is hinged to the pedestal 8 through an eighth rotating shaft, and a control rod 87 is rotatably connected to the rotating seat 85. A screw sleeve 86 is hinged to the wing plate 83 through a ninth rotating shaft. The control rod 87 is threadedly connected to the screw sleeve 86. The axial directions of the eighth rotating shaft and the ninth rotating shaft are both parallel to the axial direction of the seventh rotating shaft. Limiting blocks 88 are fixedly connected to both ends of the pushing block 72 along the length direction of the turning plate 7. Third inclined surfaces 89 for the limiting wheels 84 to abut against are arranged on the lower surfaces of the two limiting blocks 88, and the side of the third inclined surface 89 close to the pushing block 72 is inclined downward.

[0052] The operator controls the wing plate 83 to turn downward by rotating the control rod 87, so that the limit wheel 84 abuts against the third inclined surface 89 on the lower surface of the limit block 88, restricting the turnover plate 7 from disengaging from the roller 73, improving the stability of the turnover plate 7 on the mounting frame 53, and further improving the mounting stability of the drive motor 13 on the mounting frame 53.

[0053] The implementation principle of the embodiment of the present application is as follows: When the operator needs to install a longer barrel 11 and the originally reserved installation position of the barrel 11 on the base 1 is not long enough, the operator needs to adjust the positions of the first sliding table 16 and the second sliding table 17 to vacate more space for installing the base barrel.

[0054] In the initial state, the first sliding table 16 and the second sliding table 17 are fixed to each other by the connecting rod 3, and the limiting rod 22 on the first sliding table 16 is inserted into the corresponding first limiting groove 26 and the second limiting groove 23. Before the operator moves the first sliding table 16, loosen each limiting nut 28 and make the inserting cylinder 29 disengage from the first through hole 27 and the second through hole 24. The operator turns over the limiting rod 22 to make the limiting rod 22 disengage from the first limiting groove 26 and the second limiting groove 23, thereby releasing the fixing effect between the first sliding table 16 and the base 1. The operator pushes the first sliding table 16 to a suitable position, aligns the second limiting groove 23 with the first limiting groove 26 at the corresponding position, and aligns the second through hole 24 with the first through hole 27 at the corresponding position. The operator turns over the limiting rod 22 to make the limiting rod 22 inserted into the first limiting groove 26 and the second limiting groove 23, and then the operator tightens the limiting nut 28 and makes the inserting cylinder 29 inserted into the first through hole 27 and the second through hole 24 to fix the position of the first sliding table 16 on the base 1.

[0055] When the operator needs to replace the gearbox 12 or the drive motor 13 of different specifications, the operator separates the first slide 16 and the second slide 17 so as to facilitate the operator to install and disassemble the gearbox 12 or the drive motor 13. When adjusting the distance between the first slide 16 and the second slide 17, the operator loosens the lock nut 49, turns the locking rod 47 out of the locking groove 48, and then the operator moves the slider 42 so that the connecting rod 3 is disengaged from the pressure plate 43. The operator turns the connecting rod 3 so that between the first rack 4 and the second rack 41, and then the operator adjusts the relative position between the connecting rod 3 and the slide base 31, and adjusts the relative position between the first rack 4 and the second rack 41. After completing the position adjustment between the connecting rod 3 and the slide base 31, the operator moves the slider 42 so that the connecting rod 3 is re-inserted between the pressure plate 43 and the slider 42, and the first inclined surface 44 abuts against the second inclined surface 45. The operator turns the locking rod 47 so that the locking rod 47 is re-inserted into the locking groove 48. Finally, the operator tightens the lock nut 49 so that the lock nut 49 abuts tightly against the vertical plate 46. At this time, the connecting rod 3 presses the first rack 4 against the second rack 41, restricting the relative displacement between the first slide 16 and the second slide 17, and realizing the rough adjustment of the position between the first slide 16 and the second slide 17. The operator finely adjusts the position between the first slide 16 and the second slide 17 by turning the first stud 33 to drive the two slide bases 31 to slide.

[0056] For drive motors 13 or gearboxes 12 of different size specifications, the operator can control the lift 51 driven by the motor 52 to control the lifting of the lifting platform to adjust the height of the drive motor 13; the operator can adjust the horizontal position and angle of the mounting bracket 53 by rotating the two second studs 61 to adjust the horizontal position and horizontal angle of the drive motor 13; the operator adjusts the position of the push block 72 by rotating the third stud 71, and further adjusts the vertical angle of the turning plate 7 to adjust the vertical angle of the drive motor 13. By adjusting the position and angle of the drive motor 13, more drive motors 13 of different sizes can be connected to the gearbox 12.

[0057] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
