Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of filter membrane, in particular to a high-efficiency filter membrane assembly. BACKGROUND

[0002] As the core carrier of medium separation technology, filter membrane (full name: microporous filter membrane) is widely used in various fields due to its advantages of retaining impurities by membrane pores and simple processing flow. The structure sealing of high-efficiency filter membrane assembly, as an integrated application unit of filter membrane, directly determines the filtration precision and operation stability. The core structure of the existing filter membrane assembly usually includes a membrane shell and an end cover. The connection mode of the two is mainly hoop connection. Two semicircular hoops are spliced at the connection of the membrane shell and the end cover. The fastening is realized by tightening the bolts at both ends of the hoop. At the same time, a sealing ring is arranged at the joint surface of the membrane shell and the end cover. The sealing ring is elastically deformed by the pressing force of the hoop to fill the gap between the joint surfaces and achieve sealing. However, before tightening the bolts, the first hoop body and the second hoop body are easy to rotate or fall off relative to the membrane shell, resulting in that the installation is not quick and convenient.

[0003] Chinese patent CN218012089U discloses a quick-assembly membrane shell of a water treatment device. An annular groove is formed on the connecting cylinder. A rubber sleeve is arranged in the annular groove, and a gap is left between the rubber sleeve and the first fixed step. During installation, the first hoop body and the second hoop body are first inserted into the gap, so that the first hoop body and the second hoop body can be limited, preventing the first hoop body and the second hoop body from falling off quickly. The distance of the gap is less than the thickness of the first hoop body and the second hoop body. The rubber sleeve can extrude the first hoop body and the second hoop body, further preventing the first hoop body and the second hoop body from falling off. However, during the process of inserting the first hoop body and the second hoop body into the gap and tightening the bolts, the first hoop body and the second hoop body will slide against the surface of the sealing ring, which will push the sealing ring to move, causing the sealing ring to deviate from the preset sealing position of the membrane shell and the end cover. The sealing ring is not pressed uniformly with the joint surface of the membrane shell and the end cover, and gaps appear in some areas, which eventually leads to a decline in sealing effect and affects the normal use of the filter membrane assembly.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] An embodiment of a high-efficiency filtration membrane module of the present invention, such as... Figures 1 to 13 As shown.

[0021] A high-efficiency filtration membrane module includes a membrane housing 100 and two end caps 200. The membrane housing 100 is vertically oriented, and the two end caps 200 are respectively fitted onto both ends of the membrane housing 100. A sealing ring 300 is fitted at the connection between the end cap 200 and the membrane housing 100. A clamping assembly 400 is provided on the sealing ring 300. The clamping assembly 400 includes two clamping bodies and two connecting members 430. The two clamping bodies are semi-circular structures and can be mated together. The two connecting members 430 are respectively located at the mating points of the two clamping bodies.

[0022] The two clamping bodies are referred to as the first clamping body 410 and the second clamping body 420, respectively. The connecting member 430 includes a first rotating plate 431, a second rotating plate 432, a first centering plate 433, and a second centering plate 434. The first rotating plate 431 is rotatably mounted on the first clamping body 410 via a first rotating sleeve 435, and the second rotating plate 432 is rotatably mounted on the second clamping body 420 via a second rotating sleeve 436. Both the first rotating sleeve 435 and the second rotating sleeve 436 are arranged vertically and can be connected by a pin. The surfaces of the first centering plate 433 and the second centering plate 434 are rough and elastic. The first centering plate 433 is fixedly mounted on the first clamping body 410, and the second centering plate 434 is fixedly mounted on the second clamping body 420. The first centering plate 433 can abut against the second rotating sleeve 436, and the second centering plate 434 can abut against the first rotating sleeve 435.

[0023] The clamp assembly 400 has a first state and a second state. In the first state, both the first rotating sleeve 435 and the second rotating sleeve 436 abut against the sealing ring 300 and can rotate relative to the sealing ring 300 in a vertical direction. In the second state, the second rotating sleeve 436 abuts against the first centering plate 433 and the two can rotate relative to each other, and the first rotating sleeve 435 abuts against the second centering plate 434 and the two can rotate relative to each other.

[0024] In this embodiment, the first rotating plate 431 and the first clamping body 410 are configured as separate units with a rotatable fit, and the second rotating plate 432 and the second clamping body 420 are configured as separate units with a rotatable fit. When installing the clamping assembly 400, the operator first places the end cap 200 onto one end of the diaphragm housing 100, and then places a sealing ring 300 at the connection between the end cap 200 and the diaphragm housing 100. Then, the first clamping body 410 and the second clamping body 420 are clamped at the sealing ring 300, and the first clamping body 410 and the second clamping body 420 are gradually brought closer together for docking. At this time, the clamping assembly 400 is in the first state. The first rotating sleeve 435 and the second rotating sleeve 436 are both in contact with the sealing ring 300, and the first rotating sleeve 435 and the second rotating sleeve 436 can rotate relative to the sealing ring 300 in the vertical direction, so that rolling friction occurs between the sealing ring 300 and the first rotating sleeve 435 and the second rotating sleeve 436. This prevents the first clamping body 410 and the second clamping body 420 from pushing the sealing ring 300 to move synchronously during the docking process, causing the sealing ring 300 to shift, thereby improving the tightness of the fit between the sealing ring 300 and the membrane shell 100 and the end cap 200.

[0025] During the process of the first clamping body 410 and the second clamping body 420 gradually approaching and docking, when the first centering plate 433 abuts against the second rotating sleeve 436, and the second centering plate 434 abuts against the first rotating sleeve 435, the first clamping body 410 and the second clamping body 420 have basically reached their final docking position. The surfaces of both the first centering plate 433 and the second centering plate 434 are roughened to increase the friction between the first centering plate 433 and the second rotating sleeve 436, and between the second centering plate 434 and the first rotating sleeve 435. This pre-fixes the first clamping body 410 and the second clamping body 420, preventing them from falling off. Afterwards, the first rotating plate 431 and the second rotating plate 432 can be manually rotated.

[0026] See Figure 12 and Figure 13 As shown, the first rotating plate 431 and the second rotating plate 432 are brought closer together in the vertical direction. Rotation of the first rotating plate 431 causes the second centering plate 434 to move via the first rotating sleeve 435, which in turn moves the second clamping body 420. Rotation of the second rotating plate 432 causes the first centering plate 433 to move via the second rotating sleeve 436, which in turn moves the first clamping body 410, further bringing the first clamping body 410 and the second clamping body 420 closer together, enabling a tight fit and reducing alignment adjustment time during installation, thus improving installation efficiency. Finally, a pin passing through the first rotating sleeve 435 and the second rotating sleeve 436 completes the connection.

[0027] In a further embodiment, the first clamping body 410 is provided with a first mating sleeve 411 for rotatably engaging with the first rotating sleeve 435, and the second clamping body 420 is provided with a second mating sleeve 421 for rotatably engaging with the second rotating sleeve 436. Both the first mating sleeve 411 and the second mating sleeve 421 are provided with snap-fit ​​sleeves 422, which are retractable relative to their corresponding first and second mating sleeves 411 and 421. The snap-fit ​​sleeve 422 and the second rotating sleeve 436 on the first mating sleeve 411 are arranged sequentially around the circumferential direction of the first clamping body 410, and the snap-fit ​​sleeve 422 on the first mating sleeve 411 is wedge-shaped at the end near the second rotating sleeve 436 around the circumferential direction of the first clamping body 410. The snap-fit ​​sleeve 422 and the first rotating sleeve 435 on the second mating sleeve 421 are arranged sequentially around the circumferential direction of the second clamping body 420, and the snap-fit ​​sleeve 422 on the second mating sleeve 421 is wedge-shaped at the end near the first rotating sleeve 435 around the circumferential direction of the second clamping body 420.

[0028] The device comprises two first rotating sleeves 435 and two second rotating sleeves 436. The two first rotating sleeves 435 are arranged vertically on the first rotating plate 431, and the two second rotating sleeves 436 are arranged vertically on the second rotating plate 432. The first rotating sleeves 435 and the second rotating sleeves 436 are alternately distributed vertically.

[0029] Specifically, the first mating sleeve 411 and the second mating sleeve 421 are both connected to their corresponding snap-fit ​​sleeves 422 through the first elastic element 412. The first elastic element 412 is arranged in the vertical direction and is a spring.

[0030] In this embodiment, by providing snap-fit ​​sleeves 422 on both the first mating sleeve 411 and the second mating sleeve 421, during the docking process of the first clamping body 410 and the second clamping body 420, the first rotating sleeve 435 on the first rotating plate 431 will gradually approach the snap-fit ​​sleeve 422 on the second mating sleeve 421 and pass through the wedge-shaped surface on the snap-fit ​​sleeve 422, causing the snap-fit ​​sleeve 422 to be compressed back into the second mating sleeve 421. Similarly, the second rotating sleeve 436 on the second rotating plate 432 will gradually approach the snap-fit ​​sleeve 422 on the first mating sleeve 411 and pass through the wedge-shaped surface on the snap-fit ​​sleeve 422, causing the snap-fit ​​sleeve 422 to be compressed back into the first mating sleeve 411. Before the first clamping body 410 and the second clamping body 420 complete docking, the first mating sleeve 411 will not be completely coaxial with the second rotating sleeve 436, and the second mating sleeve 421 will not be completely coaxial with the first rotating sleeve 435, that is, the snap-fit ​​sleeve 422 is in a compressed state. After the first clamping body 410 and the second clamping body 420 are connected, the first mating sleeve 411 will be coaxial with the second rotating sleeve 436, and the second mating sleeve 421 will also be coaxial with the first rotating sleeve 435. At this time, the snap-fit ​​sleeve 422 on the first mating sleeve 411 and the snap-fit ​​sleeve 422 on the second mating sleeve 421 will be reset under the action of the first elastic element 412, so that the snap-fit ​​sleeve 422 on the first mating sleeve 411 can automatically insert into the second rotating sleeve 436, and the snap-fit ​​sleeve 422 on the second mating sleeve 421 can automatically insert into the first rotating sleeve 435. Before the pin is inserted, the first clamping body 410 and the second clamping body 420 are further locked to prevent the first clamping body 410 and the second clamping body 420 from falling off.

[0031] In a further embodiment, when the clamp assembly 400 switches from the first state to the second state, the arc length corresponding to the angle of rotation of the first rotating sleeve 435 and the second rotating sleeve 436 around the vertical direction is equal to the arc length traversed by the first rotating sleeve 435 and the second rotating sleeve 436 on the sealing ring 300.

[0032] In use, the diameters of the first rotating sleeve 435 and the second rotating sleeve 436 can be adjusted by changing the diameter of the diaphragm housing 100. This ensures that when the sealing ring 300 is fitted between the diaphragm housing 100 and the end cap 200, the sealing ring 300 will fit the diameter of the diaphragm housing 100 and adhere to the connection between the diaphragm housing 100 and the end cap 200. From the initial contact between the first rotating sleeve 435 and the second rotating sleeve 436 and the sealing ring 300, to the contact between the first rotating sleeve 435 and the second centering plate 434, and the contact between the second rotating sleeve 436 and the first centering plate 433, the first rotating sleeve 435 and the second rotating sleeve 436 can always roll relative to the sealing ring 300. That is, when the clamp assembly 400 switches from the first state to the second state, the arc length corresponding to the angle of rotation of the first rotating sleeve 435 and the second rotating sleeve 436 around the vertical direction is equal to the arc length traversed by the first rotating sleeve 435 and the second rotating sleeve 436 on the sealing ring 300.

[0033] In another possible embodiment, two adjusting members 440 are provided on the inner ring of the first clamp body 410 and the inner ring of the second clamp body 420. The two adjusting members 440 are arranged face to face in the vertical direction, and the sealing ring 300 is located between the two adjusting members 440.

[0034] The adjusting component 440 includes a first adjusting ring 441 and two second adjusting rings 442. The first adjusting ring 441 has a semi-circular structure and is coaxially arranged with its corresponding first clamp body 410 or second clamp body 420. Both second adjusting rings 442 have an arc-shaped structure and are coaxially arranged with the first adjusting ring 441. Both second adjusting rings 442 in the same adjusting component 440 are connected to the first rotating plate 431 on their corresponding first clamp body 410, or to the second rotating plate 432 on their corresponding second clamp body 420, via a connecting rope 443. In the vertical direction, the first adjusting ring 441 is located between the second adjusting rings 442 and the sealing ring 300, and abuts against both the second adjusting rings 442 and the sealing ring 300. The surfaces of the first adjusting rings 441 and 442 that abut against each other are both inclined surfaces.

[0035] The inner ring of the first clamp body 410 and the inner ring of the second clamp body 420 each have two grooves 413. The two grooves 413 are arranged sequentially in the vertical direction. The adjusting member 440 is arranged in a one-to-one correspondence with the grooves 413, and the adjusting member 440 is located in the groove 413 that is arranged in relation to it.

[0036] In this embodiment, by setting an adjusting member 440, when the first rotating plate 431 and the second rotating plate 432 are manually rotated, the first rotating plate 431 and the second rotating plate 432 in the same connecting member 430 rotate slightly in the vertical direction, constantly moving closer and further away from each other. When the first rotating plate 431 and the second rotating plate 432 in the same connecting member 430 move closer to each other in the vertical direction, the tension on the connecting rope 443 increases, and a tension is applied to the second adjusting ring 442 through the connecting rope 443. The second adjusting ring 442 further transmits the force to the first adjusting ring 441 through the inclined surface that cooperates with the first adjusting ring 441, and finally the sealing ring 300 is squeezed by the first adjusting ring 441. Conversely, when the first rotating plate 431 and the second rotating plate 432 in the same connector 430 move away from each other in the vertical direction, the tension on the connecting rope 443 decreases. Consequently, the tension applied to the second adjusting ring 442 through the connecting rope 443 and the force transmitted to the first adjusting ring 441 also decrease, causing the sealing ring 300 to reset under its own elasticity. This process repeats, causing the sealing ring 300 to continuously switch between compression and recovery deformation, fine-tuning its position, eliminating any wrinkles or misalignments that may exist on the sealing ring 300, and further improving the sealing tightness.

[0037] After the first rotating plate 431 and the second rotating plate 432 in the same connector 430 rotate slightly several times in the vertical direction, the rotation amplitude is increased, causing the first centering plate 433 to move the first clamping body 410, and the second centering plate 434 to move the second clamping body 420, thus aligning the first clamping body 410 and the second clamping body 420 into place. It should be noted that even with increased rotation amplitude of the first rotating plate 431 and the second rotating plate 432 in the vertical direction, the force exerted on the sealing ring 300 will not cause significant deformation of the sealing ring 300, and will not affect the sealing effect of the sealing ring 300 between the end cap 200 and the diaphragm shell 100.

[0038] In a further embodiment, the connector 430 further includes a clamping assembly 450, which includes a main frame 451 and two clamping rods 452. The main frame 451 is detachably mounted at the joint between the first clamping body 410 and the second clamping body 420. Specifically, bolts can be used to mount the main frame 451 at the joint between the first clamping body 410 and the second clamping body 420.

[0039] Two clamping rods 452 are sequentially arranged on the main frame 451 along the reference axis, and can move closer to or further away from each other along the reference axis, which is the tangent direction of the first clamping body 410. The end face of the first rotating plate 431 facing the first clamping body 410 is called the first end face, and the end face of the second rotating plate 432 facing the second clamping body 420 is called the second end face. The two clamping rods 452 abut against the first end face and the second end face, respectively. When the two clamping rods 452 move closer to each other on the main frame 451 along the reference axis, the first rotating plate 431 and the second rotating plate 432 can rotate around the vertical direction and move closer to each other. When the two clamping rods 452 move further away from each other on the main frame 451 along the reference axis, the first rotating plate 431 and the second rotating plate 432 can rotate around the vertical direction and move further away from each other.

[0040] The clamping assembly 450 also includes a screw 453, which is arranged on the main frame 451 along the reference axis and can rotate around its own axis. The screw 453 is screwed with two clamping rods 452, and the rotation of the screw 453 around its own axis can make the two clamping rods 452 move closer or further away from each other along the reference axis.

[0041] The clamping assembly 450 also includes a motor and a temperature sensing element. The motor is fixedly mounted on the main frame 451 and can drive the screw 453 to rotate around its own axis. The temperature sensing element is mounted on the main frame 451 and includes a temperature sensor and a control module. The temperature sensor is electrically connected to the motor through the control module. The temperature sensor is used to sense the temperature of the diaphragm housing 100 and convert it into an output signal that is transmitted to the control module, which then starts and stops the motor. A drive gear is fixedly mounted at the output end of the motor, and a driven gear is coaxially and fixedly connected to the screw 453. The drive gear meshes with the driven gear.

[0042] Specifically, the screw 453 is provided with a first threaded section and a second threaded section. The first threaded section is used to screw onto one of the clamping rods 452, and the second threaded section is used to screw onto the other clamping rod 452. The helical directions of the first threaded section and the second threaded section are opposite.

[0043] Furthermore, the clamping assembly 450 also includes a limiting rod 454, which is disposed on the main frame 451 along the reference axis and slides in engagement with the two clamping rods 452. By setting the limiting rod 454, the movement of the two clamping rods 452 along the reference axis is limited, making the movement of the clamping rods 452 more stable.

[0044] In this embodiment, by setting up a clamping assembly 450, the movement of the two clamping rods 452 can be controlled according to the temperature inside the membrane housing 100 during use, dynamically adjusting the pressure of the sealing ring 300 and compensating for the thermal expansion and contraction deformation of the sealing ring 300.

[0045] Specifically, after the first clamp body 410 and the second clamp body 420 are connected, the main frame body 451 is installed at the connection point of the first clamp body 410 and the second clamp body 420 using bolts. The screw 453 is driven by a motor to rotate, so that the two clamping rods 452 abut against the first end face and the second end face respectively. The first rotating plate 431 and the second rotating plate 432 rotate around the vertical direction and move closer to each other, increasing the tension of the connecting rope 443. Through the transmission of force between the connecting rope 443, the second adjusting ring 442 and the first adjusting ring 441, the force of the first adjusting ring 441 on the sealing ring 300 is increased to a certain extent.

[0046] During use, when the temperature of the medium (gas) to be filtered increases, the sealing ring 300 may expand (vertically) due to thermal expansion and contraction. Therefore, when the temperature sensor detects a rise in temperature inside the membrane housing 100, the temperature sensor will drive the motor to start via the control module, and the motor will drive the screw 453 to rotate, causing the two clamping rods 452 to move away from each other along the reference axis. This reduces the tension of the connecting rope 443 on the second adjusting ring 442, and reduces the force exerted by the first adjusting ring 441 on the sealing ring 300. Similarly, when the temperature of the medium (gas) to be filtered decreases, the sealing ring 300 may shrink (vertically) due to thermal expansion and contraction. Therefore, when the temperature sensor detects a decrease in temperature inside the membrane housing 100, the temperature sensor will drive the motor to start through the control module, and the motor will drive the screw 453 to rotate, causing the two clamping rods 452 to move closer to each other along the reference axis. This will increase the tension of the connecting rope 443 on the second adjusting ring 442, and increase the force of the first adjusting ring 441 on the sealing ring 300, compensating for the cold shrinkage deformation of the sealing ring 300 and ensuring that the sealing pressure always adapts to temperature changes.

[0047] Based on the above embodiments, the specific working process is as follows: When installing the clamp assembly 400, the operator first attaches the end cap 200 to one end of the diaphragm housing 100, and then applies the sealing ring 300 at the connection between the end cap 200 and the diaphragm housing 100. Then, the first clamping body 410 and the second clamping body 420 are clamped at the sealing ring 300, and the first clamping body 410 and the second clamping body 420 are gradually brought closer together for docking. At this time, the clamping assembly 400 is in the first state. The first rotating sleeve 435 and the second rotating sleeve 436 are both in contact with the sealing ring 300, and the first rotating sleeve 435 and the second rotating sleeve 436 can rotate relative to the sealing ring 300 in the vertical direction, so that rolling friction occurs between the sealing ring 300 and the first rotating sleeve 435 and the second rotating sleeve 436. This prevents the first clamping body 410 and the second clamping body 420 from pushing the sealing ring 300 to move synchronously during the docking process, causing the sealing ring 300 to shift, thereby improving the tightness of the fit between the sealing ring 300 and the membrane shell 100 and the end cap 200.

[0048] During the docking process of the first clamping body 410 and the second clamping body 420, the first rotating sleeve 435 on the first rotating plate 431 will gradually approach the snap-fit ​​sleeve 422 provided on the second mating sleeve 421, and pass through the wedge-shaped surface on the snap-fit ​​sleeve 422, causing the snap-fit ​​sleeve 422 to be compressed back into the second mating sleeve 421. Similarly, the second rotating sleeve 436 on the second rotating plate 432 will gradually approach the snap-fit ​​sleeve 422 on the first mating sleeve 411, and pass through the wedge-shaped surface on the snap-fit ​​sleeve 422, causing the snap-fit ​​sleeve 422 to be compressed back into the first mating sleeve 411. Before the first clamping body 410 and the second clamping body 420 complete docking, the first mating sleeve 411 will not be completely coaxial with the second rotating sleeve 436, and the second mating sleeve 421 will not be completely coaxial with the first rotating sleeve 435, that is, the snap-fit ​​sleeve 422 is in a compressed state.

[0049] When the first pair of center plates 433 abuts against the second rotating sleeve 436, and the second pair of center plates 434 abuts against the first rotating sleeve 435, the first clamping body 410 and the second clamping body 420 essentially reach their final docking positions. The surfaces of both the first pair of center plates 433 and 434 are roughened to increase the friction between the first pair of center plates 433 and the second rotating sleeve 436, as well as the friction between the second pair of center plates 434 and the first rotating sleeve 435. This pre-fixes the first clamping body 410 and the second clamping body 420, preventing them from detaching. Simultaneously, the rotational arc lengths of the first rotating sleeve 435 and the second rotating sleeve 436 are equal to the arc length traversed on the sealing ring 300, ensuring constant rolling contact and avoiding sliding friction.

[0050] The first rotating plate 431 and the second rotating plate 432 can then be manually rotated. When manually rotating the first rotating plate 431 and the second rotating plate 432, the first rotating plate 431 and the second rotating plate 432 in the same connecting member 430 are first rotated slightly in the vertical direction, constantly moving closer and further away from each other. When the first rotating plate 431 and the second rotating plate 432 in the same connecting member 430 move closer to each other in the vertical direction, the tension on the connecting rope 443 increases, and a tension is applied to the second adjusting ring 442 through the connecting rope 443. The second adjusting ring 442 will further transmit the force to the first adjusting ring 441 through the inclined surface that cooperates with the first adjusting ring 441, and finally the sealing ring 300 is squeezed by the first adjusting ring 441. Conversely, when the first rotating plate 431 and the second rotating plate 432 in the same connector 430 move away from each other in the vertical direction, the tension on the connecting rope 443 decreases. Consequently, the tension applied to the second adjusting ring 442 through the connecting rope 443 and the force transmitted to the first adjusting ring 441 also decrease, causing the sealing ring 300 to reset under its own elasticity. This process repeats, causing the sealing ring 300 to continuously switch between compression and recovery deformation, fine-tuning its position, eliminating any wrinkles or misalignments that may exist on the sealing ring 300, and further improving the sealing tightness.

[0051] After the first rotating plate 431 and the second rotating plate 432 in the same connector 430 rotate slightly several times in the vertical direction, the rotation amplitude is increased, causing the first centering plate 433 to move the first clamping body 410, and the second centering plate 434 to move the second clamping body 420, thus aligning the first clamping body 410 and the second clamping body 420 into place. It should be noted that even with increased rotation amplitude of the first rotating plate 431 and the second rotating plate 432 in the vertical direction, the force exerted on the sealing ring 300 will not cause significant deformation of the sealing ring 300, and will not affect the sealing effect of the sealing ring 300 between the end cap 200 and the diaphragm shell 100.

[0052] After the first clamping body 410 and the second clamping body 420 are connected, the first mating sleeve 411 will be coaxial with the second rotating sleeve 436, and the second mating sleeve 421 will also be coaxial with the first rotating sleeve 435. At this time, the snap-fit ​​sleeves 422 on the first mating sleeve 411 and the second mating sleeve 421 will be reset under the action of the first elastic element 412, so that the snap-fit ​​sleeves 422 on the first mating sleeve 411 can automatically insert into the second rotating sleeve 436, and the snap-fit ​​sleeves 422 on the second mating sleeve 421 can automatically insert into the first rotating sleeve 435. Before the pin is inserted, the first clamping body 410 and the second clamping body 420 are further locked to prevent them from falling off. Finally, the pin is passed through the coaxial first rotating sleeve 435 and second rotating sleeve 436 to complete the final locking of the clamping assembly 400.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
