Description

Technical Field

[0001] This invention belongs to the field of chemical air filter technology, and specifically relates to a chemical air filter. Background Technology

[0002] Industrial development has led to a significant increase in the emission of chemical pollutants such as volatile organic compounds (VOCs), nitrogen oxides, sulfides, formaldehyde, and ammonia into the atmosphere. Simultaneously, indoor decoration, furniture release, and the operation of electronic devices have exacerbated the problem of chemical pollution in enclosed spaces. These chemical pollutants not only cause a decline in indoor air quality but can also enter the human body through respiration. Long-term exposure can easily induce respiratory diseases, allergic reactions, and even increase the risk of cancer, posing a serious threat to human health. Therefore, there is an urgent need for efficient air purification technologies to remove chemical pollutants from the air. Chemical air filters are one such technology; they utilize chemical filter media to filter polluted gases, offering a significantly more effective filtration compared to traditional filtration methods, greatly improving the treatment efficiency of polluted gases.

[0003] However, existing chemical air filters are composed of an outer filter cover and an inner filter cover, with chemical filter media filled between the outer and inner filter covers, and then fastened by a tension screw. This assembly method requires tools to complete both disassembly and assembly, and the tension screw needs to be twisted repeatedly, which is very inconvenient to use and makes it difficult to clean and replace the chemical filter media. Summary of the Invention

[0004] This invention provides a chemical air filter, which aims to solve the problem that existing chemical air filters require tools to disassemble and assemble, and require repeated twisting of the tension screw, making them very inconvenient to use, and consequently difficult to clean and replace the chemical filter media.

[0005] This invention provides a chemical air filter, comprising a mounting plate with several filter inlets. An inner filter cover is fixed to the back of the mounting plate, which completely covers the filter inlets. A frame is attached to the back of the mounting plate, and the frame covers the outside of the inner filter cover. Several outer filter covers are installed on the frame, each corresponding to the outer of the inner filter cover. Chemical filter media particles are filled in the gap between the inner and outer filter covers. Several supports are installed on the frame, and the supports are connected to the mounting plate via a connecting module. The connecting module includes a connecting post A, with a T-shaped opening at its upper end. A T-shaped rod slides into the T-shaped opening. After the outer filter cover and mounting plate are assembled, the bottom of the T-shaped rod is flush with the upper end inside the T-shaped opening, and the upper end of the T-shaped rod extends out of the connecting post A and is fixed to the bracket. An annular opening is provided at the lower end of the connecting post A. A connecting component is installed on the outside of the connecting post A, comprising a connecting platform and a fastening module. The connecting platform supports the connecting post A, and its lower end is fixed to the mounting plate. The fastening module includes a fastening unit and a spiral beryllium copper wire. The fastening unit is installed on the connecting platform, with one side serving as a guide end. The guide end includes a conical platform, and the inclined wall of the conical platform is angled downwards towards the side closest to the connecting post A. The unit can switch between a fastened state and an open state. When the fastening unit is in the fastened state, one side of the guide end on the fastening unit is inserted into the annular opening to fasten the connecting post A. When the fastening unit is in the open state, one side of the guide end on the fastening unit moves out of the annular opening to loosen the connecting post A. The connector also includes a traction unit, which is installed on the connecting platform and connected to the fastening unit. One side of the spiral beryllium copper wire is mounted on the connecting platform or the traction unit, and the other side of the spiral beryllium copper wire is connected to or in close contact with the fastening unit. The spiral beryllium copper wire gives the fastening unit the momentum to maintain the fastened state. The operation of the traction unit can pull the fastening unit to change, so that the fastening unit can be switched to the open state. The traction unit includes a rotating ring and a moving platform that are connected to each other. The rotating ring is screwed onto the connecting platform, one side of the moving platform is screwed onto the connecting platform, and the other side of the moving platform is screwed onto the fastening unit. The rotating ring can pull the moving platform to rotate, thereby pulling the fastening unit to move. The connecting platform is ring-shaped, and the rotating ring is screwed onto the outer circumference of the connecting platform. The traction unit also includes a connecting plate, which is assembled between the rotating ring and the changing platform. The connecting plate can pull the changing platform to rotate. The connecting plate is arched and arches towards the inside of the connecting platform.

[0006] Furthermore, a sealing element is installed between the mounting plate and the outer filter cover. The sealing element includes a sealing groove reserved on the back of the mounting plate and located on the side of the filter inlet, and a sealing strip fixed to the opening of the outer filter cover. The sealing strip is engaged in the sealing groove.

[0007] Furthermore, the fastening unit includes a transmission column and a connecting column B that are connected to each other. The angle between the transmission column and the connecting column B is 90 degrees. The side of the connecting column B that is farther from the transmission column is connected to the guide end. A groove is reserved on the moving platform. A protrusion is installed on the transmission column. The protrusion is movable in the groove. When the rotating ring pulls the moving platform to rotate, the protrusion can move in the groove to pull one side of the guide end on the fastening unit to move out of the annular opening.

[0008] Furthermore, the fastening module also includes an assembly table, which is mounted on the connecting table and has a pre-reserved assembly opening. The connecting post B can pass through the assembly opening. One side of the spiral beryllium copper wire is tightly attached to the assembly table, and the other side of the spiral beryllium copper wire is tightly attached to the guide end. When the protrusion moves in the groove, the connecting post B moves in the assembly opening. The guide end can press the spiral beryllium copper wire to shorten so that one side of the guide end on the fastening unit moves out of the annular opening.

[0009] Furthermore, the connector also includes a constraint rod, which is installed on the connecting platform. The rotating ring has a waist-shaped groove that extends along the rotation direction of the rotating ring, and the constraint rod can be embedded in the waist-shaped groove.

[0010] Furthermore, the connector also includes a constraint platform B, which is mounted on the connector platform and can constrain the traction unit from moving off the connector platform.

[0011] Furthermore, several fastening modules are installed in a ring along the connecting platform, and the fastening units on the fastening modules are all connected to the traction unit.

[0012] The beneficial effects of this invention are as follows: This invention supports the connecting post A via a connecting platform. A fastening module with a spiral beryllium copper wire provides the fastening unit with the momentum to maintain its fastened position. The spiral beryllium copper wire keeps the fastening unit engaged in the annular opening on the connecting post A. When the connecting post A is fastened to the connecting platform, the fastening unit has a guide end on one side, which includes a conical platform. When the connecting post A moves towards the connecting platform, the bottom of the connecting post A adheres tightly to the inclined wall of the conical platform. Moving along the inclined wall of the conical platform, it presses the fastening unit towards the side farther from the connecting post A. The spiral beryllium copper wire shortens, and as the connecting post A moves downwards, the fastening unit moves outwards. When the connecting post A presses downwards until the annular opening is directly opposite the fastening unit, the fastening unit is secured. One side of the fastening unit, equipped with a guide end, moves into the annular opening with the assistance of a spiral beryllium copper wire. During this process, there is no need to drive the fastening module; simply pressing the connecting post A downwards toward the connecting platform is sufficient for rapid fastening. Furthermore, a traction unit is installed on the connecting platform, which is connected to the fastening unit. When the connecting post A needs to be disassembled, the traction unit is driven, pulling the fastening unit out of the annular opening. At this point, the connecting post A can be quickly removed by pulling it outwards. After the connecting post A is removed, there is no need to re-drive the traction unit; the fastening unit automatically returns to its fastened position with the assistance of the spiral beryllium copper wire. This allows for rapid fastening of the connecting post A the next time it needs to be fastened, ensuring the rapid assembly and disassembly of the connecting post A and its stability. This facilitates operation and makes it easier to replace the internal chemical filter media particles.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] Reference Figure 1 , Figure 2 and Figure 4 This invention provides a chemical air filter, comprising a mounting plate 1 with several filter inlets 2 pre-drilled on it. An inner filter cover 3 is fixed to the back of the mounting plate 1, completely covering the filter inlets 2. A frame 4 is attached to the back of the mounting plate 1, covering the outer side of the inner filter cover 3. Several outer filter covers 5 are mounted on the frame 4, each corresponding to the outer side of the inner filter cover 3. Chemical filter media particles are filled in the gap between the inner filter cover 3 and the outer filter covers 5. Several supports 6 are mounted on the frame 4, and the supports 6 are L-shaped. The supports 6 are connected to the mounting plate 1 via a connecting module 7, which is used for the rapid assembly and disassembly of the mounting plate 1 and the frame 4 to facilitate cleaning of the filter interior.

[0017] Reference Figure 4 and Figure 5 A sealing element is installed between the mounting plate 1 and the outer filter cover 5. The sealing element includes a sealing groove 11 reserved on the back of the mounting plate 1 and located on the side of the filter inlet 2, and a sealing strip 41 fixed to the opening of the outer filter cover 5. The sealing strip 41 is engaged in the sealing groove 11 to ensure the sealing between the outer filter cover 5 and the mounting plate 1.

[0018] Reference Figure 2 , Figure 3 and Figures 6-9 The connecting module 7 includes a connecting post A610, with a T-shaped opening at the upper end of the connecting post A610. A T-shaped rod 620 is slidably fastened into the T-shaped opening. After the outer filter cover 5 and the mounting plate 1 are assembled, the bottom of the T-shaped rod 620 is tightly fitted to the upper end inside the T-shaped opening, and the upper end of the T-shaped rod 620 extends out of the connecting post A610 and is fixedly connected to the bracket 6. An annular opening 6101 is reserved at the lower end of the connecting post A610, and a connecting component is installed on the outside of the connecting post A610. The connecting component includes... The connecting platform 61 and the fastening module 62 are used to support the connecting post A610. The lower end of the connecting platform 61 is fixed to the mounting plate 1. The fastening module 62 includes a fastening unit 621 and a spiral beryllium copper wire 622. The fastening unit 621 is installed on the connecting platform 61. One side of the fastening unit 621 is a guide end 6211. The guide end 6211 includes a conical platform 62111. The inclined wall of the conical platform 62111 is inclined from top to bottom towards the side closest to the connecting post A610. Assume that the fastening unit 621 can switch between a fastened state and an open state. When the fastening unit 621 is in the fastened state, the guide end 6211 on the fastening unit 621 is inserted into the annular opening 6101 to fasten the connecting post A610. When the fastening unit 621 is in the open state, the guide end 6211 on the fastening unit 621 moves out of the annular opening 6101 to loosen the connecting post A610. The connector also includes a traction unit 63. Installed on the connecting platform 61, the traction unit 63 and the fastening unit 621 are connected. One side of the spiral beryllium copper wire 622 is mounted on the connecting platform 61 or the traction unit 63, and the other side of the spiral beryllium copper wire 622 is connected to or in close contact with the fastening unit 621. The spiral beryllium copper wire 622 gives the fastening unit 621 the momentum to maintain the fastened state. The operation of the traction unit 63 can pull the fastening unit 621 to move, so that the fastening unit 621 can be switched to the open state. The fastening module 62 also includes an assembly platform 623, which is mounted on the connecting platform 61. One side of the spiral beryllium copper wire 622 is tightly attached to the assembly platform 623, and the other side of the spiral beryllium copper wire 622 is connected to or tightly attached to the fastening unit 621. That is, the spiral beryllium copper wire 622 is mounted on the connecting platform 61 via the assembly platform 623, which facilitates the assembly of the fastening unit 621 and ensures that the fastening unit 621 has the momentum to maintain its fastened state. Furthermore, the spiral beryllium copper wire 622 can also be mounted on the connecting platform 61 or the traction unit 63.

[0019] The connecting platform 61 supports the connecting post A610. The fastening module 62, with its spiral beryllium copper wire 622, allows the fastening unit 621 to maintain its fastened position. The spiral beryllium copper wire 622 keeps the fastening unit 621 engaged in the annular opening 6101 on the connecting post A610. When the connecting post A610 is fastened to the connecting platform 61, the fastening unit 621 has a guide end 6211 on one side. Furthermore, the guide end 6211 includes a conical platform 62111. When the connecting post A610 moves towards one side of the connecting platform 61, the bottom of the connecting post A610 is tightly attached to the inclined wall of the conical platform 62111, and moves on the inclined wall of the conical platform 62111, thereby pressing the fastening unit 621 to move towards the side farther from the connecting post A610. The spiral beryllium copper wire 622 shortens, and the fastening unit 621 moves outward as the connecting post A610 presses downward. When the annular opening 6101 is aligned with the fastening unit 621, one side of the fastening unit 621, equipped with the guide end 6211, moves into the annular opening 6101 with the assistance of the spiral beryllium copper wire 622. During this process, it is not necessary to drive the fastening module 62; simply pressing the connecting post A610 downwards towards the connecting platform 61 achieves rapid fastening. Furthermore, by installing a traction unit 63 on the connecting platform 61, which is connected to the fastening unit 621, when the connecting post A610 needs to be disassembled... Drive the traction unit 63, and the traction fastening unit 621 moves out of the annular opening 6101. At this moment, the connecting post A610 can be quickly removed by pulling it outward. After removing the connecting post A610, there is no need to drive the traction unit 63 again. With the cooperation of the spiral beryllium copper wire 622, the fastening unit 621 will automatically return to the fastened state so that the connecting post A610 can be quickly fastened next time. This ensures that the assembly and disassembly of the connecting post A610 is quick and stable, which is convenient for operation.

[0020] Reference Figure 8 and Figure 9 The traction unit 63 includes a rotating ring 631 and a moving platform 632 connected to each other. The rotating ring 631 is screwed onto the connecting platform 61, one side of the moving platform 632 is screwed onto the connecting platform 61, and the other side of the moving platform 632 is screwed onto the fastening unit 621. The rotating ring 631 can pull the moving platform 632 to rotate, thereby pulling the fastening unit 621 to move.

[0021] When the rotating ring 631 moves, it pulls the rotating platform 632 to rotate. The side of the rotating platform 632 connected to the fastening unit 621 moves, which in turn pulls the fastening unit 621 to move, so that the guide end 6211 on the fastening unit 621 moves out of the annular opening 6101, thereby achieving the purpose of quickly disassembling the connecting column A610, enhancing the smoothness of the movement of the fastening unit 621, and thus speeding up the disassembly rate of the connecting column A610.

[0022] The connecting platform 61 is circular, and the rotating ring 631 is screwed onto the outer circumference of the connecting platform 61. This structure reduces the area occupied by the connecting platform 61 and the rotating ring 631, and enhances the ease of movement of the rotating ring 631, thereby reducing the area occupied by the connecting parts and enhancing the ease of operation of the connecting parts.

[0023] Several fastening modules 62 are installed circumferentially along the connecting platform 61, and the fastening units 621 on the fastening modules 62 are all connected to the traction unit 63. This structure can perform multiple fastenings on the connecting column A610 from the circumference of the connecting platform 61, further enhancing the stability of the fastening of the connecting column A610. Multiple fastenings can prevent the connecting column A610 from not being aligned with the connecting platform 61, enhancing the matching of the connecting column A610 and achieving rapid and accurate fastening. Moreover, the movement of the traction unit 63 can move several fastening units 621 at the same time, further enhancing the convenience of the connection operation.

[0024] The traction unit 63 also includes a connecting piece 633, which is assembled between the rotating ring 631 and the moving platform 632. The connecting piece 633 can pull the moving platform 632 to rotate. This structure increases the connection distance between the rotating ring 631 and the moving platform 632 to prevent interference with other components when the rotating ring 631 and the moving platform 632 are moving, thus enhancing the suitability of the connecting structure.

[0025] The connecting piece 633 is arched, and the arched connecting piece 633 arches towards the inner side of the connecting platform 61. The arching of the connecting piece 633 towards the inner side of the connecting platform 61 increases the force exerted by the rotating ring 631 on the moving platform 632 towards the outside of the connecting platform 61 when it rotates, making it easier to pull the moving platform 632 to rotate and enhancing the smoothness of the connecting parts control.

[0026] The connector also includes a constraint rod 64, which is mounted on the connector platform 61. The rotating ring 631 has a pre-drilled slot 63111 extending along the rotational direction of the rotating ring 631, and the constraint rod 64 can be fitted into the slot 63111. This structure prevents the rotating ring 631 from over-rotating and damaging the traction unit 63, thus enhancing the reliability of the connector.

[0027] Several constraint rods 64 and several waist-shaped grooves 63111 are installed, and several constraint rods 64 and several waist-shaped grooves 63111 are paired with each other. This structure once again prevents the rotating ring 631 from rotating too much and causing damage to the traction unit 63, and further enhances the reliability of the connecting parts.

[0028] The fastening unit 621 includes a transmission column 6212 and a connecting column B6213 that are connected to each other. The angle between the transmission column 6212 and the connecting column B6213 is 90 degrees. The side of the connecting column B6213 that is farther away from the transmission column 6212 is connected to the guide end 6211. The moving platform 632 has a pre-reserved groove 6321. The transmission column 6212 is equipped with a protrusion 6214, which is movably installed in the groove 6321. When the rotating ring 631 pulls the moving platform 632 to rotate, the protrusion 6214 can move in the groove 6321 to pull one side of the guide end 6211 on the fastening unit 621 out of the annular opening 6101.

[0029] When the rotating platform 632 rotates, the protrusion 6214 can move within the groove 6321 on the rotating platform 632. Since the angle between the transmission column 6212 and the connecting column B6213 is ninety degrees, the rotation of the rotating platform 632 can become the moving stroke of the connecting column B6213, thereby allowing the guide end 6211 on the fastening unit 621 to move out of the annular opening 6101. The structure is simple, the movement is smooth, and the suitability of the connecting component structure is enhanced.

[0030] Reference Figure 8 and Figure 9 The assembly table 623 is mounted on the connecting table 61 and has a pre-reserved assembly opening. The connecting post B6213 can pass through the assembly opening. One side of the spiral beryllium copper wire 622 is tightly attached to the assembly table 623, and the other side of the spiral beryllium copper wire 622 is tightly attached to the guide end 6211. When the protrusion 6214 moves within the groove 6321, the connecting post B6213 moves within the assembly opening. The guide end 6211 can compress the spiral beryllium copper wire 622 to shorten it, allowing one side of the guide end 6211 on the fastening unit 621 to move out of the annular opening 6101. This structure allows the spiral beryllium copper wire 622 to cooperate with the fastening unit 621 via the assembly table 623, and prevents the assembly table 623 from interfering with the movement of the connecting post B6213 via the assembly opening, thus enhancing the suitability of the connector structure.

[0031] Both the drive column 6212 and the connecting column B6213 are columnar. This structure can reduce the weight and size of the fastening unit 621, and the columnar connecting column B6213 can move well within the assembly port, enhancing the smoothness of the connecting parts.

[0032] The guide end 6211 also includes a constraint platform A62112, which is mounted on the side of the conical platform 62111 furthest from the connecting post A610. The spiral beryllium copper wire 622 coincides with the central axis of the assembly port. The connecting post B6213 can pass through the assembly port and the spiral beryllium copper wire 622, which is tightly attached between the assembly platform 623 and the constraint platform A62112. This structure allows the connecting post B6213 to pass through the spiral beryllium copper wire 622, preventing interference between the spiral beryllium copper wire 622 and the connecting post B6213, reducing the size of the fastening module 62, and enhancing the suitability of the connector structure by constraining the spiral beryllium copper wire 622 through the installed constraint platform A62112. When the connecting post A610 is disassembled, the driving rotating ring 631 causes the constraint table A62112 to suppress the deformation of the spiral beryllium copper wire 622. The connecting post B6213 moves in the assembly port toward the side farther from the annular opening 6101, which allows the guide end 6211 on the fastening unit 621 to move out of the annular opening 6101.

[0033] The rotating ring 631 includes an assembly end 6311, which is ring-shaped and clamped to the outer surface of the connecting platform 61. The assembly end 6311 can rotate on the connecting platform 61 to pull the rotating platform 632 to rotate. This structure allows the assembly end 6311 to rotate on the connecting platform 61, thereby reducing the difficulty of the assembly end 6311 pulling the rotating platform 632 to rotate and enhancing the ease of operation of the connecting parts.

[0034] The rotating ring 631 also includes a traction end 6312, which is mounted on the outside of the mounting end 6311. This configuration allows the user to grasp the traction end 6312 to rotate the mounting end 6311, enhancing ease of operation.

[0035] Reference Figure 7 The inner surface of the connecting platform 61 has a pre-drilled assembly groove A611, and the upper surface of the connecting platform 61 has a pre-drilled assembly groove B612. The assembly platform 623 is assembled in the assembly groove B612, and one side of the guide end 6211 on the fastening unit 621 can pass through the assembly groove A611 and then be inserted into the annular opening 6101. This structure provides a range of assembly and adjustment for the assembly platform 623 and the fastening unit 621, enhancing the smoothness and stability of fastening and disassembly, thereby enhancing the reliability of the connecting parts control.

[0036] The upper end of the connecting platform 61 is also reserved with an assembly slot C613, in which a column is installed. The side of the movable platform 632 furthest from the protrusion 6214 is reserved with an assembly port A, which is screwed onto the column. This structure allows the movable platform 632 to be screwed onto the connecting platform 61, so that the movable platform 632 can pull the fastening unit 621 to move, thus enhancing the suitability of the connecting structure.

[0037] The rotating platform 632 has an assembly port B, and the assembly end 6311 has a connection port. Columns are installed on both sides of the connecting piece 633, and a pair of columns are screwed into the assembly port B and the connection port respectively. This structure enhances the stability and smoothness of the rotating platform 632 when the connecting piece 633 pulls it, preventing jamming and thus improving the reliability of the connecting components.

[0038] The connector also includes a constraint platform B65, which is mounted on the connector platform 61 and can constrain the traction unit 63 from moving off the connector platform 61. This architecture enhances the reliability of the connector's operation.

[0039] The constraint table B65 is sheet-like and arranged in groups, with each group of constraint tables B65 vertically mounted on the connecting table 61. This structure can constrain the traction unit 63 to the connecting table 61, thereby preventing the traction unit 63 from moving out of the connecting table 61 and further enhancing the reliability of the connecting parts.

[0040] In use, move the connecting column A610 toward the connecting platform 61 until the bottom of the connecting column A610 is in close contact with the inclined wall of the conical platform 62111. Move the connecting column A610 along the inclined wall toward the connecting platform 61, driving the fastening unit 621 toward the side farther from the connecting column A610; After the connecting column A610 is moved to the assembly position, the fastening unit 621 is pressed into the annular opening 6101 by the spiral beryllium copper wire 622; When the connecting post A610 is removed, the driving traction unit 63 and the traction fastening unit 621 suppress the deformation of the spiral beryllium copper wire 622 and move it out of the annular opening 6101 before removing the connecting post A610.

[0041] When fastening the connecting post A610 to the connecting platform 61, because the guide end 6211 on the fastening unit 621 includes a conical platform 62111, when the connecting post A610 moves toward one side of the connecting platform 61, the bottom of the connecting post A610 is tightly attached to the inclined wall of the conical platform 62111, and moves on the inclined wall of the conical platform 62111. Then, the fastening unit 621 is pressed to compress the deformation of the spiral beryllium copper wire 622, which moves toward the side farther away from the connecting post A610. When the connecting post A610 is pressed downward to the annular opening 6101 facing the fastening unit 621, one side of the guide end 6211 on the fastening unit 621 is pushed into the annular opening 6101 by the spiral beryllium copper wire 622. During this process, no operation is required on the fastening module 62. Only pressing the connecting post A610 downward toward the connecting platform 61 is needed to achieve the purpose of rapid fastening.

[0042] When disassembling the connecting post A610, the driving traction unit 63 and the traction fastening unit 621 suppress the deformation of the spiral beryllium copper wire 622 and move it out of the annular opening 6101. At this time, the connecting post A610 can be quickly removed by pulling it upwards. After removing the connecting post A610, there is no need to drive the traction unit 63 again. With the cooperation of the spiral beryllium copper wire 622, the fastening unit 621 automatically resets to the fastened state, which makes it easy to quickly fasten the connecting post A610 the next time it is fastened. This ensures the fastening and disassembly speed and reliability of the connecting post A610.

[0043] Reference Figure 10 When the connecting part is in the fastened state, the guide end 6211 on the fastening unit 621 extends to the outside of the assembly groove A611, the spiral beryllium copper wire 622 is in the extended state, and the protrusion 6214 on one side of the transmission column 6212 is at the innermost part of the groove 6321.

[0044] Reference Figure 11 When the connector needs to be switched to the open position, the drive assembly end 6311 rotates on the connecting table 61, and then the connecting piece 633 pulls the rotating table 632 to rotate, so that the protrusion 6214 on one side of the transmission column 6212 moves to the outer side of the groove 6321, and then pulls the fastening unit 621 to move to the side farther away from the annular opening 6101, and the spiral beryllium copper wire 622 is in the shortened position.
