Description

Technical Field

[0001] The invention relates to the technical field of grinding and polishing, and in particular to a filter housing polishing device. Background Art

[0002] During the processing of the filter housing, a flat and smooth surface needs to be obtained, which is generally achieved through polishing. The polishing process includes grinding, polishing and restoration. Grinding is usually done by pre-treating the surface with water sandpaper to remove surface dirt, oxidation, fine scratches and surface defects, and then polishing the ground surface with a polishing agent and a polishing disc to make it smooth, and finally coloring and restoring it.

[0003] For example, the patent with application number 202322065878.0 and name “A cavity filter housing polishing device” “adds a dust collecting shell and a dust suction mechanism, and opens multiple dust suction ports inside the dust collecting shell, which can timely absorb the generated dust and fine particles to prevent them from adhering to the surface of the outer shell or entering the interior of the equipment. This can effectively reduce the risk of pollution and blockage and keep the outer shell clean. These fans form an airflow channel through the dust collecting shell and the protective shell to achieve air intake and exhaust circulation.”

[0004] Although the dust generated during polishing can be sucked away by adding a dust collecting shell and a dust suction mechanism, in the actual operation process, the applicant found that the above patent and the existing filter housing polishing equipment have at least the following deficiencies: since in the polishing process, dust is only generated when the sandpaper grinds the surface, and no dust is generated when the polishing agent is polished, the dust particles can indeed be sucked away by the dust suction mechanism during the sandpaper grinding process, but in the process of suction, since the dust particles move from bottom to top, they will constantly collide with the sandpaper, which will seriously affect the effect of sandpaper grinding and cannot really avoid the interference of dust particles on grinding; furthermore, dust will not be generated during the polishing process of the polishing agent, and the polishing will partially splash onto the polishing equipment during the polishing process, which will easily cause the vents on the equipment to be blocked, and the dust suction mechanism will produce an upward suction force on the polishing agent, causing more polishing agent to enter the equipment and more easily block the vents, unless after the grinding is completed, the polishing equipment without vents is replaced, so that the polishing agent can avoid clogging the vents, but such operation requires the use of two devices in conjunction, which will inevitably increase the cost. It can be seen from this that how to implement the grinding process and polishing process on the same polishing equipment, so as to avoid the adverse effects of dust particles on grinding during the grinding process and prevent the polishing agent from clogging the equipment vents during the polishing process, is a technical problem that needs to be solved urgently. Summary of the invention

[0005] The object of the present invention is to provide a filter housing polishing device to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solution: a filter housing polishing device, comprising a housing, and further comprising:

[0018] In the filter housing polishing device, a gear is fixedly mounted on one end of the blade, a plurality of hiding holes corresponding to the plurality of blades are opened on the outer ring plate, and the blades are arranged in the hiding holes so as to rotate around the axis of the gear.

[0019] The above-mentioned filter housing polishing equipment, the linkage includes a slide plate and a rotating plate, the slide plate is slidably connected to the inner plate, one end of the rotating plate is rotatably connected to the slide plate, and the other end is rotatably connected to the hiding hole through an axle, and the rotating plate is provided with meshing teeth that mesh with the gear.

The inner plate is also provided with multiple insertion holes corresponding to the multiple slides one by one, and the slides are connected to the insertion holes. During the downward movement of the inner plate, the rotating plate rotates while pulling the slides to slide toward the inner wall of the insertion hole until the slide and the insertion hole clamp the grinding disk.

[0021] The filter housing polishing device mentioned above has a gap between the inner plate and the outer ring plate for inserting the polishing disc, and an extrusion edge is formed on the rotating plate. During the upward movement of the inner plate, the rotating plate is driven to rotate around the axis so that the extrusion edge squeezes the polishing disc to clamp and fix the polishing disc in the gap.

[0024] Beneficial effect: In the above technical scheme, a filter housing polishing device provided by the present invention drives multiple linkage parts to rotate multiple blades when relative movement occurs between the inner plate and the outer ring plate. The rotation of the blades enables the blades to be flipped to the outside of the outer ring plate and to be flipped into the inside of the outer ring plate. When the blades are located on the outside of the outer ring plate, downward airflow can be generated as the blades rotate. The technical effect produced is that the downward airflow can blow away the dust particles generated during grinding so as not to affect the grinding effect. When the blades are located inside the outer ring plate, the rotation of the blades cannot form a downward airflow. The technical effect produced is that if the downward airflow still exists The polishing agent will be blown away during polishing. Therefore, the blades of the present invention are automatically hidden inside the outer ring plate during polishing, which can effectively avoid the downward airflow that affects the polishing effect. At the same time, there will be no problem of the polishing agent blocking the vent of the equipment. Moreover, the fixation of the polishing disc and the grinding disc is achieved by the cooperation of the linkage and the inner plate. Therefore, the present invention only needs the same polishing equipment to realize the grinding process and the polishing process, and can blow the dust particles in during the grinding process to avoid the adverse effect of the dust particles on the grinding. In addition, the polishing agent will not block the vent of the equipment during the polishing process, which can effectively solve the shortcomings of the prior art.

[0025] In the present invention, the rotation of the blade is passively realized when the grinding disc and the polishing disc are installed, so that the blade automatically flips to the outside of the outer ring plate when the grinding disc is installed, and automatically flips to the inside of the outer ring plate when the grinding disc is removed and the polishing disc is installed, eliminating the operation of adjusting the position of the blade separately;

[0026] Furthermore, the fixation of the polishing disc and the grinding disc during installation is achieved through the cooperation between the linkage and the inner plate, so that the linkage can not only control the position of the blade, but also fix the polishing disc and the grinding disc, producing an unexpected technical effect, without the need to set up a separate fixing mechanism;

[0027] Secondly, grinding and polishing are all done by this equipment, and only the polishing disc and grinding disc need to be replaced, which saves costs;

[0028] At the same time, in the prior art, when removing the grinding disc, the hands are removed at the bottom of the grinding disc, which is very easy to come into contact with the grinding disc. Since the grinding disc will generate high temperature during grinding, it is very easy to scald the operator when the grinding disc is removed immediately. However, the present invention only requires rotating the fastening ring to eliminate the squeezing force of the linkage on the grinding disc. Under the action of its own gravity, the grinding disc will automatically fall and be removed. The fastening ring is far away from the grinding disc, so the grinding disc will not come into contact with the hands, and there will be no risk of scalding the operator, thereby improving operational safety.

DETAILED DESCRIPTION

[0046] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] like Figure 1-14 As shown, a filter housing polishing device provided by an embodiment of the present invention includes a housing, and further includes:

[0048] An outer ring plate 6 is rotatably disposed in the housing, and a plurality of blades 24 arranged circumferentially are rotatably disposed on the outer ring plate 6;

[0049] The inner plate 5 is sleeved in the outer ring plate 6, and the inner plate 5 and the plurality of blades 24 are linked by a linking member;

[0050] The shaft rod 3 is axially slidable, the bottom of the shaft rod 3 is fixedly connected to the axis of the inner plate 5, and the shaft rod 3 is connected to the motor 15 through the coupling tube 14;

[0051] A fastening ring 4, which is screwed onto the shaft 3 and is used to lock the shaft 3 at an upper limit position and a lower limit position;

[0052] A grinding disc 26 for grinding the housing surface;

[0053] A polishing disc 25, which is used to polish the housing surface;

[0054] When the shaft 3 drives the inner plate 5 to move to the lower limit position, the multiple linkages clamp the grinding disc 26 and drive the multiple blades 24 to flip downward so that the shaft 3 drives the grinding disc 26 to rotate during grinding, driving the multiple blades 24 to rotate to form a downward airflow to blow away the dust particles;

[0055] When the shaft 3 drives the inner plate 5 to move to the upper limit position, multiple linkages clamp and fix the polishing disc 25 while driving multiple blades 24 to flip upward into the outer ring plate 6 so that the shaft 3 drives the polishing disc 25 to rotate and the blades 24 will not form a downward airflow to blow away the polishing agent during polishing.

[0056] The filter housing polishing equipment provided in this embodiment is used to perform two processes of grinding and polishing on the filter housing in sequence, so as to solve the technical problem that the dust particles generated during grinding do not affect the continuous grinding, and the technical problem that the polishing agent does not clog the equipment or the polishing agent is blown away during polishing. Specifically, in this embodiment, the bottom surface of the grinding disc 26 is a sandpaper surface, which is used to grind the filter housing, and the polishing disc 25 is used to polish the filter housing with the polishing agent. The fixation of the polishing disc 25 and the grinding disc 26 is achieved by the cooperation of the linkage and the inner plate 5 (the specific implementation method is described in detail below). The motor 15 is fixedly installed in the housing, and the power output end of the motor 15 is coaxially fixedly connected to the coupling tube 14. The shaft rod 3 and the coupling tube 14 are connected with a sliding key so that the shaft rod 3 can both slide axially and be driven to rotate by the coupling tube 14. By starting the motor 15 The coupling tube 14 is driven to rotate, and the coupling tube 14 in turn drives the shaft rod 3 to rotate. The bottom of the shaft rod 3 is axially fixedly connected to the inner plate 5, so that when the shaft rod 3 rotates, the inner plate 5 is driven to rotate synchronously. Similarly, when the shaft rod 3 moves axially up and down, it can drive the inner plate 5 to move up and down synchronously. The shaft rod 3 has an upper limit position and a lower limit position. The fastening ring 4 is used to lock the shaft rod 3 at the upper limit position and the lower limit position. When the shaft rod 3 is locked, it cannot move axially and can only be driven to rotate by the coupling tube 14. At this time, the inner plate 5 is also axially locked and cannot move axially and can only rotate. The outer ring plate 6 and the inner plate 5 are in a sleeve relationship, and the inner plate 5 is located on the inner side of the outer ring plate 6. The outer ring plate 6 is rotatably connected to the shell and cannot move axially. Therefore, when the shaft rod 3 drives the inner plate 5 to move axially, the outer ring plate 6 remains in motion, thereby causing relative movement between the inner plate 5 and the outer ring plate 6. The multiple blades 24 arranged on the outer ring plate 6 are connected to the inner plate 5 through multiple linkages. When relative movement occurs between the inner plate 5 and the outer ring plate 6, the multiple linkages drive the multiple blades 24 to rotate. The rotation of the blades 24 enables the blades 24 to flip to the outside of the outer ring plate 6 or to flip into the inside of the outer ring plate 6. When the blades When the blade 24 is located outside the outer ring plate 6, a downward airflow can be generated as the blade 24 rotates. The technical effect is that the downward airflow can blow away the dust particles generated during grinding to avoid affecting the grinding effect. When the blade 24 is located inside the outer ring plate 6, the rotation of the blade 24 cannot form a downward airflow. The technical effect is that if the downward airflow still exists, the polishing agent will be blown away during polishing. Therefore, in the present invention, the blade 24 is automatically hidden inside the outer ring plate 6 during polishing, which can effectively avoid the generation of downward airflow and affect the polishing effect. At the same time, there will be no problem of polishing agent clogging the air vents of the equipment.

[0057] In the present invention, the rotation of the blade 24 is passively realized when the grinding disc 26 and the polishing disc 25 are installed, so that the blade 24 automatically flips to the outside of the outer ring plate 6 when the grinding disc 26 is installed, and the blade 24 automatically flips to the inside of the outer ring plate 6 when the grinding disc 26 is removed and the polishing disc 25 is installed, eliminating the operation of adjusting the position of the blade 24 separately, and the blade 24 can generate airflow only when the blade 24 is required to generate downward airflow, which is also one of the innovations of the present invention; the second innovation is that the fixation of the polishing disc 25 and the grinding disc 26 during installation is achieved by the mutual cooperation of the linkage and the inner plate 5, so that the linkage can not only control the position of the blade 24, but also fix the polishing disc 25 and the grinding disc 26, producing an unexpected technical effect, and no separate The third innovation is that grinding and polishing are both completed by the device, and only the polishing disc 25 and the grinding disc 26 need to be replaced, which saves costs; the fourth innovation is that in the prior art, when removing the grinding disc 26, the hands are removed at the bottom of the grinding disc 26, which is very easy to touch the grinding disc 26. Since the grinding disc 26 will generate high temperature during grinding, it is very easy to scald the operator when the grinding disc 26 is removed immediately. However, the present invention only needs to rotate the fastening ring 4 to make the squeezing force of the linkage on the grinding disc 26 disappear. Under the action of its own gravity, the grinding disc 26 will automatically fall and be removed. Moreover, the fastening ring 4 is far away from the grinding disc 26, so the grinding disc 26 will not contact the hands, and thus there will be no risk of scalding the operator, thereby improving the safety of operation.

[0058] The working principle is as follows: first, the fastening ring 4 is rotated to the initial position, at which time the shaft 3 is located between the upper limit position and the lower limit position, and then the grinding disc 26 is put on the inner plate 5, and then a downward force is applied to the shaft 3 to make the shaft 3 move downward, and in the process of the shaft 3 moving downward, the inner plate 5 is driven to move downward synchronously, and because the outer ring plate 6 is stationary, the process of the inner plate 5 moving downward drives the linkage to clamp the grinding disc 26 while driving the corresponding blades 24 to flip downward so that multiple blades 24 are synchronously flipped to the outside of the outer ring plate 6, and after the linkage clamps the grinding disc 26, the fastening ring 4 is rotated so that the fastening ring 4 axially locks the shaft 3 in the lower limit position, thereby making the inner plate 5 also axially locked, thereby keeping the grinding disc 26 clamped and fixed, and multiple blades 24 remain flipped on the outside of the grinding disc 26 as shown in the figure. Fig. 9 , 11As shown in Figures 1, 12, 13, and 14, the motor 15 is then started to drive the coupling tube 14 to rotate, the coupling tube 14 drives the shaft rod 3 to rotate, the shaft rod 3 drives the inner plate 5 to rotate, the inner plate 5 drives the outer ring plate 6 to rotate through the linkage while driving the grinding disc 26 to rotate, the rotation of the outer ring plate 6 drives multiple blades 24 to rotate and generate a downward airflow, the rotation of the grinding disc 26 realizes the grinding of the filter housing, and the dust particles generated during the grinding process are blown away by the airflow generated by the blades 24, thereby not affecting the quality of continuous grinding; after the grinding is completed, the fastening ring 4 is rotated in the opposite direction to release the axial locking of the shaft rod 3, at this time the grinding disc 26 falls off under the action of its own gravity, and then the polishing disc 25 is put on the inner plate 5, at this time the round side of the polishing disc 25 is located between the inner plate 5 and the outer ring plate 6, and then an upward force is applied to the shaft rod 3, the shaft rod 3 The inner plate 5 is driven to move upward. During the upward movement of the inner plate 5, the linkage is driven to clamp and fix the polishing disc 25 while driving the blades 24 to rotate to the inside of the outer ring plate 6. After the linkage clamps the polishing disc 25, the fastening ring 4 is rotated in the opposite direction so that the fastening ring 4 axially locks the shaft 3 at the upper limit position, so that the inner plate 5 is also axially locked, thereby keeping the polishing disc 25 clamped and fixed, and the multiple blades 24 remain in the state of being located inside the outer ring plate 6. Then the motor 15 is started again to drive the polishing disc 25 to rotate for polishing. Since the multiple blades 24 are located inside the outer ring plate 6, no downward airflow is generated during rotation, and the polishing agent is not blown away. In addition, the present invention does not generate upward airflow, so the polishing agent will not enter the interior of the equipment, and will not block the equipment vents. The present invention does not require the provision of vents. It can be seen that the present invention only needs the same polishing equipment to realize the grinding process and the polishing process, and can blow away the dust particles during the grinding process to avoid the adverse effects of the dust particles on the grinding. In addition, the polishing agent will not clog the air holes of the equipment during the polishing process, which can effectively solve the shortcomings of the prior art.

[0059] In this embodiment, the shell includes an upper shell 1 and a lower shell 2 that are fixedly connected, the lower shell 2 includes a fixedly arranged lower cover 201, a fixed plate 13 is fixedly connected to the lower cover 201 through a second connecting column 12, the shaft 3 slides through the fixed plate 13 and the lower cover 201 in sequence, the fastening ring 4 is screwed on the shaft 3 through a thread 301, the fastening ring 4 is located between the fixed plate 13 and the lower cover 201, and there is a height difference between the fixed plate 13 and the lower cover 201, which is used to provide an operating space for rotating the fastening ring 4, the number of the second connecting columns 12 is at least two to maintain the firmness between the fixed plate 13 and the lower cover 201, and a connecting plate 202 is fixedly installed on the lower shell 2, and a plurality of first connecting columns are fixedly installed between the connecting plate 202 and the upper shell 1 11 is used to realize the fixed connection between the upper shell 1 and the lower shell 2. A vertical plate is also fixedly installed between the connecting plate 202 and the upper shell 1. The vertical plate and the upper shell 1 are connected as a whole. A handle 16 is fixedly installed on the vertical plate and the upper shell 1. When the inner plate 5 moves to the upper limit position, the fastening ring 4 squeezes the lower cover 201 so that the shaft rod 3 cannot move downward. At the same time, the linkage clamps the polishing disk 25 so that the shaft rod 3 cannot move upward, thereby realizing that the shaft rod 3 is locked in the upper limit position and cannot move axially; when the inner plate 5 moves to the lower limit position, the fastening ring 4 squeezes the fixed plate 13 so that the shaft rod 3 cannot continue to move upward. At the same time, the linkage clamps the grinding disk 26 so that the shaft rod 3 cannot move downward, thereby realizing that the shaft rod 3 is locked in the lower limit position and cannot move axially.

[0060] Among them, the motor 15 is fixedly installed in the upper shell 1, the top of the upper shell 1 is the upper cover 101, and the upper cover 101 is provided with ventilation holes for heat dissipation of the motor 15. The power output end of the motor 15 is coaxially fixedly connected with the coupling tube 14, and the shaft rod 3 is slidably inserted in the coupling tube 14. A flat key 1401 is integrally provided inside the coupling tube 14, and an inner groove 303 for sliding insertion of the flat key 1401 is provided on the shaft rod 3. The sliding insertion cooperation between the flat key 1401 and the inner groove 303 enables the shaft rod 3 to move axially up and down and be driven to rotate by the coupling tube 14.

[0061] In this embodiment, an extension ring 601 is fixedly provided on the outer peripheral surface of the outer ring plate 6, and two limit members 203 arranged opposite to each other in an upper and lower direction are fixedly provided inside the lower shell 2. The extension ring 601 rotates and is located between the two limit members 203. The limit member 203 includes a ring body and a plurality of balls rollingly embedded in the ring body. The balls abut against the side surfaces of the extension ring 601. The ring body and the interior of the lower shell 2 are welded to limit the extension ring 601 and prevent the extension ring 601 from axial movement, so that the outer ring plate 6 cannot move axially. At the same time, the abutment between the balls and the extension ring 601 can effectively reduce friction and ensure smooth rotation of the outer ring plate 6.

[0062] Among them, a gear 23 is fixedly installed at one end of the blade 24, and a plurality of hiding holes 602 corresponding to the plurality of blades 24 are opened on the outer ring plate 6. The blade 24 is rotatably arranged in the hiding hole 602 around the axis of the gear 23. Specifically, two supporting cylinders 22 arranged opposite to each other are fixedly installed inside the blade 24, and the gear 23 is rotatably arranged between the two supporting cylinders 22. When the gear 23 rotates, the blade 24 is driven to rotate synchronously.

[0063] In this embodiment, the linkage includes a slide plate 20 and a rotating plate 19. The slide plate 20 is slidably connected to the inner plate 5. One end of the rotating plate 19 is rotatably connected to the slide plate 20, and the other end is rotatably connected to the hiding hole 602 through the shaft body 21. The shaft body 21 is fixedly connected or rotatably connected to the hiding hole 602. The rotating plate 19 is provided with meshing teeth 1901 that mesh with the gear 23. During the up and down movement of the inner plate 5, the rotating plate 19 is driven to rotate around the shaft body 21 so that the meshing teeth 1901 drive the gear 23 and the blade 24 to rotate. When the inner plate 5 moves down, the rotating plate 19 drives the blade 24 to flip downward to the outside of the outer ring plate 6. When the inner plate 5 moves up, the rotating plate 19 drives the blade 24 to flip upward to the inside of the outer ring plate 6. Among them, there are multiple meshing teeth 1901 and they are arranged circumferentially around the axis of the shaft body 21. The tooth groove on the gear 23 is inclined, so that the meshing teeth 1901 can effectively mesh with the gear 23 when rotating.

[0064] And the sliding plate 20 can be pulled to slide during the rotation of the rotating plate 19 .

[0065] Specifically, the inner plate 5 is provided with slideways 501 corresponding to the multiple slideways 20 one by one, and the slideways 20 are slidably arranged in the slideways 501. The inner plate 5 is also provided with multiple insertion holes 502 corresponding to the multiple slideways 501 one by one, and the slideways 501 are connected with the insertion holes 502. When the inner plate 5 moves downward, the rotating plate 19 rotates and pulls the slideway 20 to slide toward the inner wall of the insertion hole 502 until the slideway 20 and the insertion hole 502 clamp the grinding disc 26. Specifically, the insertion hole 502 passes through the top and bottom of the inner plate 5, and the grinding disc 26 includes a plurality of clamping pieces 2601 that are fixedly arranged and correspond one-to-one to the plurality of insertion holes 502. When the grinding disc 26 is installed, the plurality of clamping pieces 2601 are inserted one-to-one into the plurality of insertion holes 502 from the bottom, and the arc edge of the grinding disc 26 is located on the outer side of the inner plate 5. When the slide plate 20 continuously slides toward the inner wall of the insertion hole 502, the outer side surface of the slide plate 20 continuously squeezes the clamping piece 2601 so that the plurality of clamping pieces 2601 are clamped and fixed in the insertion hole 502, thereby achieving fixed installation of the grinding disc 26. The side surface of the clamping piece 2601 is adapted to the side surface of the slide plate 20 and the side surface of the insertion hole 502, so that the clamping piece 2601 fits with the side surface of the slide plate 20 and the side surface of the insertion hole 502 when being clamped, so as to increase the contact area and improve firmness.

[0066] Furthermore, a gap 17 is formed between the inner plate 5 and the outer ring plate 6 for inserting the polishing disc 25, and an extrusion edge 1902 is formed on the rotating plate 19. When the inner plate 5 moves upward, the rotating plate 19 is driven to rotate around the shaft 21 so that the extrusion edge 1902 squeezes the polishing disc 25 and clamps and fixes the polishing disc 25 in the gap 17. Specifically, an inner ring plate is fixedly provided on the inner side of the polishing disc 25. When the polishing disc 25 is installed, the inner ring plate is inserted into the gap 17, and the inner wall of the inner ring plate fits the outer side of the inner plate 5. The polishing disc 25 is sleeved on the outer side of the outer ring plate 6. As the inner plate 5 moves upward, the rotating plate 19 is driven to rotate so that the extrusion edge 1902 continuously squeezes the inner ring plate on the polishing disc 25 until the inner ring plate on the polishing disc 25 is pressed by the extrusion edge 1902 and the inner plate 5 to fix the polishing disc 25.

[0067] A wing edge 302 is fixedly provided on the shaft rod 3, and a first ring 9 is slidably sleeved on the shaft rod 3. The first ring 9 is fixedly connected to the outer ring plate 6 through the first fixed plate 7. The inner side of the first ring 9 is also provided with a limiting groove for the wing edge 302 to slide into. Based on the sliding connection between the wing edge 302 and the limiting groove, the outer ring plate 6 can be driven to rotate synchronously when the shaft rod 3 rotates. This method can make the shaft rod 3 drive the inner plate 5 and the outer ring plate 6 to rotate at the same time, so that in the process of the inner plate 5 driving the outer ring plate 6 to rotate, the force of the linkage can be effectively shared to prevent the linkage from being damaged and deformed.

[0068] In addition, a second ring 10 is also sleeved on the shaft 3. The second ring 10 has the same structure as the first ring 9. The second ring 10 is fixedly connected to the inner plate 5 through the second fixing plate 8 so that the inner plate 5 can be driven to rotate synchronously when the shaft 3 rotates, thereby reducing the force between the bottom of the shaft 3 and the inner plate 5 and preventing the shaft 3 from generating radial deformation.

[0069] Among them, a plug-in tube 18 is fixedly installed at the center position of the inner plate 5, the bottom of the shaft 3 is inserted in the plug-in tube 18, and the plug-in tube 18 is inserted with a pin 1801, which passes through the shaft 3, so that when the shaft 3 rotates, the inner plate 5 can be driven to rotate through the plug-in tube 18 and the pin 1801.

[0070] In this embodiment, the thread 301 is divided into two sections, an upper section and a lower section, so that the number of turns of the fastening ring 4 can be effectively reduced when the position of the fixed shaft 3 is switched.

[0071] Each of the plurality of hiding holes 602 is provided with an escape opening 603 , which is communicated with the hiding holes 602 and is used to escape the rotating plate 19 so that the rotating plate 19 can rotate smoothly.

[0072] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
