Description

Technical Field

[0001] The utility model relates to the technical field of diving grippers, in particular to a gripper for diving. Background Art

[0002] Diving is an activity that enters the water surface or below with or without professional tools for underwater exploration, salvage, repair, and underwater engineering operations. It has gradually developed into a leisure sport with underwater activities as the main content to achieve the purpose of physical exercise and leisure entertainment; while a gripper is a device that holds an object and then manipulates the object. It can clamp and release an object while performing certain actions. Sports equipment often imitates human movements. In the case of a gripper, it imitates the movement of fingers. The "fingers" themselves do not belong to the gripper. They are only special customized tools for gripping objects, called "clip pieces".

[0003] The existing Chinese patent with the reference publication number of CN108098820B discloses an underwater manual gripper for a humanoid manned submersible, including a jaw assembly, a pressure-resistant shell of the submersible, and a gripper body; wherein, the upper part of the gripper body passes through the pressure-resistant shell of the submersible, and the lower part of the gripper body is in the external seawater environment. The bottom of the gripper body is connected to the jaw assembly, and the jaw assembly is completely in the seawater environment; the force transmission and direction conversion are carried out by using a gear rack, and the axial gripping force generated by the driver is converted into a circumferential torque through the gear rack structure, and the jaws are driven to open and close by the torque. And the gear components are all in the seawater environment, so that the external seawater pressure is in a balanced state on the gear components and cannot have a negative impact on the driver's gripping force, greatly reducing the driving force required for the movement of the jaws.

[0004] Although this structure has the effect of making the external seawater pressure in a balanced state on the gear components and not having a negative impact on the driver's gripping force, its structure is complex and the manufacturing cost is relatively high. In general situations, most items are grabbed manually by divers. This structure does not conform to the human grasping design. When performing manual grasping, its structure needs to be processed and improved, increasing the process and reducing the work efficiency. Therefore, the inventor of the present invention has proposed a gripper for diving to solve the above-mentioned technical problems. Summary of the Utility Model

[0005] The utility model aims to provide a technical solution that can solve the above problems to overcome the above deficiencies.

[0006] A clamping device for diving, comprising a base, clamping jaws and a fixing plate. The clamping jaws are mounted on the surface of the base through a first movable rod and a second movable rod. The clamping jaws are respectively mounted at the left and right ends of the base. One end of the first movable rod abuts against the surface of the base. One end of the first movable rod abuts against the surface of the base through a retracting and releasing gear. A reversing assembly for assisting the retracting and releasing gear to change direction is mounted at one end of the base. A magnetic attraction block for gripping a magnetizable metal is connected to the surface of the clamping jaw. The magnetic attraction block and the clamping jaw are of a detachable structure. One end of the clamping jaw is in an arc shape, and the arc shape is consistent with the surface curvature of the magnetic attraction block. A driving assembly for driving the reversing assembly to operate is connected to the surface of the base;

[0007] This device integrates multiple components such as a base, clamping jaws, movable rods, retracting and releasing gears, a reversing assembly, a driving assembly, and a magnetic attraction block, achieving efficient and flexible gripping of magnetizable metals. The clamping jaws are connected to the base through a first movable rod and a second movable rod. This structure is not only stable but also can adjust the opening and closing degree of the clamping jaws according to needs to adapt to magnetizable metals of different sizes. At the same time, the arc-shaped design at both ends of the clamping jaws matches the curvature of the magnetic attraction block, ensuring a tight fit between the magnetic attraction block and the magnetizable metal, improving the stability and accuracy of gripping;

[0008] The combined use of the retracting and releasing gear and the reversing assembly makes the opening and closing actions of the clamping jaws smoother and more precise. The reversing assembly can assist the retracting and releasing gear to achieve the reversing function, thereby controlling the opening and closing direction of the clamping jaws, which is crucial for accurately gripping and releasing magnetizable metals. The driving assembly provides power support for the entire device, ensuring the smooth progress of various operations;

[0009] The detachable structure design between the magnetic attraction block and the clamping jaw provides convenient space for users. Users can choose whether to install the magnetic attraction block or replace the magnetic attraction block with different magnetic forces according to actual needs to adapt to different types of magnetizable metals. This design increases the flexibility of use;

[0010] The magnetic attraction block used in this structure, during underwater operation, due to the water pressure exerting pressure on the surface of the magnetic attraction block, can make the connection between the magnetic attraction block and the clamping jaw more stable, reducing the probability of the magnetic attraction block falling off the surface of the clamping jaw.

[0011] Furthermore, the reversing assembly includes a reversing bolt and a turntable. The surface of the reversing bolt is in a threaded shape. One end of the reversing bolt abuts against the surface of the turntable. The reversing bolt and the retracting and releasing gear are meshed. When the reversing bolt rotates, it drives the retracting and releasing gear, thereby pulling the first movable rod and causing it to drive the clamping jaw to move. During this process, the second movable rod receives the acting force of the clamping jaw movement and has the effect of limiting the position of the clamping jaw and increasing the supporting point of the clamping jaw, playing a role in stabilizing the clamping jaw;

[0012] The commutation component includes a direction-changing bolt and a turntable. The surface of the direction-changing bolt is designed in a thread shape, which enables the direction-changing bolt to generate stable axial force and friction when rotating. At the same time, the direction-changing bolt is meshed with the retracting and extending gear, ensuring stable and reliable transmission between the direction-changing bolt and the retracting and extending gear. When the direction-changing bolt rotates, it can accurately drive the retracting and extending gear to rotate accordingly, thus achieving precise control of the transmission path.

[0013] Secondly, the meshing setting also improves the transmission efficiency and reduces energy loss. Since the contact area between the direction-changing bolt and the retracting and extending gear is large and tight, power can be transmitted more effectively, making the entire transmission system more efficient. Moreover, the design also has a certain self-locking function. When the direction-changing bolt is tightened, due to the biting action of the thread, a certain pre-tightening force will be generated, causing the direction-changing bolt to maintain close contact with the turntable and between the direction-changing bolt and the retracting and extending gear, thus preventing loosening or falling off caused by vibration or external force.

[0014] Furthermore, the driving component includes a driving motor and a connecting key. One end of the driving motor is an output shaft, and the connecting key is installed on the surface of the output shaft. One end of the connecting key extends to the surface of the turntable, and the turntable is installed on the outer side of the connecting key. The direction-changing bolt, turntable, driving motor, and output shaft are coaxially arranged. One end of the driving motor is provided with a reinforcing rib and a positioning convex block.

[0015] The addition of the reinforcing rib significantly enhances the structural strength of the driving motor, enabling it to withstand a working environment with a greater working load. This structural reinforcement not only extends the service life of the motor but also improves the reliability and stability of the overall component. At the same time, the reinforcing rib can effectively disperse the vibration and stress generated by the motor during operation, reducing noise and wear caused by vibration.

[0016] The positioning convex block plays a positioning role. The positioning convex block ensures the precise position of the driving motor during installation, facilitating the operation of components such as the output shaft, connecting key, turntable, and direction-changing bolt on the same axis. This coaxial arrangement not only ensures smooth power transmission without obstruction but also avoids performance degradation and faults caused by component misalignment or loosening. In addition, the positioning convex block simplifies the installation process and improves work efficiency.

[0017] Furthermore, mounting plates are provided at both the left and right ends of the base. A number of mounting holes for connecting external screws are provided on the surface of the mounting plates, and the driving component is located between two adjacent mounting plates. This layout enables the driving component to be supported by the two mounting plates on both sides, thereby enhancing its structural stability and reliability. During operation, the driving component may be affected by various forces and vibrations, and this layout can effectively disperse these forces and vibrations, reducing the wear and failure rate of the driving component.

[0018] Secondly, placing the drive component between the mounting plates is also beneficial for improving space utilization. In a limited space, a reasonable layout can enable each component to be arranged compactly and orderly, avoiding waste of space. At the same time, this layout also helps to reduce the volume and weight, improving the portability and flexibility of the device.

[0019] Furthermore, one end of the magnetic attraction block is connected with a mounting structure for assisting the connection between the magnetic attraction block and the clamping jaw. The mounting structure includes a plug rod, a rubber clamping block, and a rubber clamping plate. The rubber clamping block is in a circular arc convex shape and is located on the outer side of the plug rod. The rubber clamping plate is installed at one end of the plug rod and has a diameter larger than that of the plug rod.

[0020] As the core component of the connection, the plug rod ensures a firm connection between the magnetic attraction block and the clamping jaw. Its design is simple and effective, and it can bear and transmit sufficient force, making the magnetic attraction block not easy to loosen or fall off during the working process. The setting of the rubber clamping block increases the friction between the plug rod and the clamping jaw, further improving the stability of the connection. The rubber material has good elasticity and wear resistance, and can relieve the stress generated by vibration or impact to a certain extent, thereby protecting the connection structure from damage.

[0021] At the same time, the circular arc convex shape design of the rubber clamping block also makes it easier to fit with the contact surface of the clamping jaw, improving the sealing and stability of the connection. The installation of the rubber clamping plate not only increases the diameter of the end of the plug rod, making the connection more firm, but also plays a role in limiting and fixing. The material and shape of the rubber clamping plate are similar to those of the rubber clamping block, and it also has good elasticity and wear resistance. During the installation process, the rubber clamping plate can be tightly clamped into the corresponding position of the clamping jaw to prevent the accidental pulling out or loosening of the plug rod.

[0022] Furthermore, a connection structure for mating installation with the mounting structure is provided inside the clamping jaw. The connection structure includes a connection groove, a clamping groove, and a limiting groove. The shapes and positions of the connection groove, the clamping groove, and the limiting groove are the same as those of the plug rod, the rubber clamping block, and the rubber clamping plate. This design ensures the precise docking and firm connection between the clamping jaw and the mounting structure. The plug rod can be accurately inserted into the connection groove to form a preliminary fixation; the rubber clamping block can be tightly clamped into the clamping groove to increase the tightness and stability of the connection; and the cooperation between the rubber clamping plate and the limiting groove further restricts the lateral movement of the clamping jaw and the magnetic attraction block, ensuring that they will not loosen or fall off during the working process.

[0023] Secondly, the design of this structure also takes into account the convenience and efficiency of installation. Since the shapes and positions of the components match each other, no complex adjustments and calibrations are required during installation. Simply insert the insertion rod, rubber clamping block, and rubber clamping plate. During the insertion process, they can be respectively aligned and inserted into the corresponding slots, greatly saving installation time and labor costs. In addition, the use of rubber material also brings additional advantages. Rubber has certain elasticity and toughness, which can absorb and relieve the impact and vibration during installation to a certain extent, protecting the clamping jaws and the installation structure from damage. At the same time, rubber also has good sealing performance, which can prevent impurities such as dust and moisture from entering the connection part and affecting the stability and reliability of the connection.

[0024] Furthermore, the fixed plate is installed on the surface of the base, and both the first movable rod and the second movable rod are connected to the fixed plate through locking screws. Adopting this connection method significantly enhances the stability of the structure. The fixed plate, as a bridge connecting the base and the first and second movable rods, its strong structure can effectively disperse and bear the force transmitted from the movable rods, thus ensuring the stability of the entire device during operation. The locking screws, through their limiting effect, limit the movable rods on the fixed plate, further enhancing the firmness of the connection, preventing the movable rods from loosening or falling off during use, and at the same time leaving space for the first and second movable rods to rotate, avoiding the first and second movable rods being locked on the fixed plate and causing the clamping jaws to be unable to move.

[0025] Secondly, this design provides good adjustment flexibility. Since the first and second movable rods are connected to the fixed plate through locking screws, the position or angle of the movable rods can be easily adjusted according to needs. This flexibility enables the entire device to adapt to different working scenarios and requirements, improving its versatility and practicality. In addition, this connection method also facilitates the maintenance and replacement of components. When the movable rods or the fixed plate are worn or damaged, simply loosen the locking screws to easily remove and replace the new components, without the need to disassemble the entire device on a large scale. This not only saves maintenance time and costs but also extends the service life of the device.

[0026] From the perspective of cost-effectiveness, this connection method is relatively simple and low-cost. The locking screws, as common fasteners, have relatively low costs and are easy to obtain. At the same time, due to the relatively simple connection structure, the manufacturing and assembly processes are also more efficient and economical. While reducing the manufacturing cost, it simplifies the installation process, achieving the effect and function of convenient installation.

[0027] Furthermore, the surface of the clamping jaw is provided with anti-slip lines for increasing the friction of grasping. The anti-slip lines are in a wedge-shaped structure. The wedge-shaped anti-slip lines arranged on the surface of the clamping jaw mainly have the advantages of enhancing the grasping friction and improving the clamping stability. The design of the wedge-shaped structure can increase the roughness of the contact surface, thereby generating greater friction when clamping an object, preventing the object from sliding or moving in the clamping jaw. This design is applicable to the occasions where stable clamping is required underwater, and can effectively ensure the accuracy and safety of clamping. In addition, the wedge-shaped structure also has a certain self-locking function, which can resist external impact forces to a certain extent and further improve the clamping stability.

[0028] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0029] 1. It realizes the efficient and flexible grasping of magnetizable metals. The clamping jaw is connected to the base through the first movable rod and the second movable rod. This structure is not only stable but also can adjust the opening and closing degree of the clamping jaw according to requirements to adapt to magnetizable metals of different sizes. At the same time, the arc surface design at both ends of the clamping jaw matches the radian of the magnetic attraction block, ensuring the close fit between the magnetic attraction block and the magnetizable metal, and improving the stability and accuracy of grasping;

[0030] 2. The combined use of the retracting and extending gear and the commutation component makes the opening and closing actions of the clamping jaw smoother and more precise. The commutation component can assist the retracting and extending gear to achieve the commutation function, thereby controlling the opening and closing direction of the clamping jaw, which is crucial for accurately grasping and releasing magnetizable metals. The driving component provides power support for the entire device to ensure the smooth progress of various operations;

[0031] 3. The detachable structure design between the magnetic attraction block and the clamping jaw provides convenient space for users. Users can choose whether to install the magnetic attraction block or replace the magnetic attraction block with different magnetic forces according to actual needs to adapt to different types of magnetizable metals. This design increases the flexibility of use and facilitates the manual holding and clamping process;

[0032] 4. The magnetic attraction block adopted in this structure is in an arc shape. When operating underwater, since the water pressure exerts pressure on the surface of the magnetic attraction block, the connection between the magnetic attraction block and the clamping jaw can be made more stable, reducing the probability of the magnetic attraction block falling off the surface of the clamping jaw.

Specific embodiments

[0040] The following further describes the present utility model in detail in conjunction with the accompanying drawings and specific embodiments.

[0041] In this embodiment, please refer to Figures 1-6 , a diving gripper specifically implemented therein includes a base 1, jaws 2 and a fixed plate 3. The jaws 2 are installed on the surface of the base 1 through a first movable rod 4 and a second movable rod 5. The jaws 2 are respectively installed at the left and right ends of the base 1. One end of the first movable rod 4 abuts against the surface of the base 1, and one end of the first movable rod 4 abuts against the surface of the base 1 through a retracting and extending gear 6. A direction - changing assembly for assisting the retracting and extending gear 6 to change direction is installed at one end of the base 1. A magnetic attraction block 7 for gripping a magnetizable metal is connected to the surface of the jaws 2. The magnetic attraction block 7 and the jaws 2 are of a detachable structure. One end of the jaws 2 is in an arc shape, and the arc shape is consistent with the surface curvature of the magnetic attraction block 7. A driving assembly for driving the operation of the direction - changing assembly is connected to the surface of the base 1;

[0042] This device integrates multiple components such as a base 1, jaws 2, movable rods, a retracting and extending gear 6, a direction - changing assembly, a driving assembly, and a magnetic attraction block 7, realizing efficient and flexible gripping of magnetizable metals. The jaws 2 are connected to the base 1 through a first movable rod 4 and a second movable rod 5. This structure is not only stable but also can adjust the opening and closing degree of the jaws 2 according to requirements to adapt to magnetizable metals of different sizes. At the same time, the arc - shaped design at both ends of the jaws 2 matches the curvature of the magnetic attraction block 7, ensuring a tight fit between the magnetic attraction block 7 and the magnetizable metal, improving the stability and accuracy of gripping;

[0043] The combined use of the retractable gear and the reversing component makes the opening and closing actions of the jaw 2 smoother and more precise. The reversing component can assist the retractable gear 6 to achieve the reversing function, thereby controlling the opening and closing direction of the jaw, which is crucial for accurately grasping and releasing magnetizable metals. The drive component provides power support for the entire device, ensuring the smooth progress of various operations;

[0044] The detachable structure design between the magnetic attraction block 7 and the jaw 2 provides a convenient space for users. Users can choose whether to install the magnetic attraction block 7 or replace the magnetic attraction block 7 with different magnetic force magnitudes according to actual needs to adapt to different types of magnetizable metals, which increases the flexibility of use;

[0045] When the magnetic attraction block 7 used in this structure is operating underwater, since the water pressure exerts pressure on the surface of the magnetic attraction block 7, the connection between the magnetic attraction block 7 and the jaw 2 can be made more stable, reducing the probability of the magnetic attraction block 7 falling off the surface of the jaw 2.

[0046] The reversing component includes a reversing bolt 8 and a turntable 9. The surface of the reversing bolt 8 is in a threaded shape. One end of the reversing bolt 8 abuts against the surface of the turntable 9. The reversing bolt 8 is meshed with the retractable gear 6. When the reversing bolt 8 rotates, it drives the retractable gear 6, thereby pulling the first movable rod 4, which in turn drives the jaw 2 to move. During this process, the second movable rod 5 is affected by the movement of the jaw 2 and has the effect of limiting the position of the jaw 2 and increasing the support point of the jaw 2, playing a role in stabilizing the jaw 2;

[0047] The reversing component includes a reversing bolt 8 and a turntable 9. The surface of the reversing bolt 8 is designed in a threaded shape. This design enables the reversing bolt 8 to generate stable axial force and friction force when rotating. At the same time, the reversing bolt 8 and the retractable gear 6 are meshed, ensuring stable and reliable transmission between the reversing bolt 8 and the retractable gear 6. When the reversing bolt 8 rotates, it can accurately drive the retractable gear 6 to rotate accordingly, thereby achieving precise control of the transmission path;

[0048] Secondly, the meshing setting also improves the transmission efficiency and reduces energy loss. Since the contact area between the reversing bolt 8 and the retractable gear 6 is large and tight, power can be transmitted more effectively, making the entire transmission system more efficient. Moreover, the design also has a certain self-locking function. When the reversing bolt 8 is tightened, due to the biting action of the threads, a certain pre-tightening force will be generated, keeping the contact between the reversing bolt 8 and the turntable 9 as well as between the reversing bolt 8 and the retractable gear 6 tight, thus preventing loosening or falling off caused by vibration or external forces.

[0049] The driving assembly includes a driving motor 10 and a connecting key 11. One end of the driving motor 10 is an output shaft 12. The connecting key 11 is installed on the surface of the output shaft 12. One end of the connecting key 11 extends to the surface of the turntable 9. The turntable 9 is installed on the outer side of the connecting key 11. The steering bolt 8, the turntable 9, the driving motor 10 and the output shaft 12 are coaxially arranged. One end of the driving motor 10 is provided with a reinforcing rib 13 and a positioning bump 14;

[0050] The addition of the reinforcing rib 13 significantly enhances the structural strength of the driving motor 10, enabling it to withstand a working environment with a greater working load. This structural reinforcement not only extends the service life of the motor but also improves the reliability and stability of the overall assembly. At the same time, the reinforcing rib 13 can effectively disperse the vibration and stress generated during the operation of the motor, reducing the noise and wear caused by vibration;

[0051] The positioning bump 14 serves a positioning function. The positioning bump 14 ensures the precise position of the driving motor 10 during the installation process, facilitating the operation of components such as the output shaft 12, the connecting key 11, the turntable 9, and the steering bolt 8 on the same axis. This coaxial arrangement not only ensures smooth power transmission without obstruction but also avoids performance degradation and faults caused by component misalignment or loosening. In addition, the positioning bump 14 simplifies the installation process and improves work efficiency.

[0052] Both the left and right ends of the base 1 are provided with mounting plates 15. The surface of the mounting plates 15 is provided with a plurality of mounting holes 16 for connecting external screws. The driving assembly is located between two adjacent mounting plates 15. This layout enables the driving assembly to be supported by the two mounting plates 15 on both sides, thereby enhancing the structural stability and reliability. During operation, the driving assembly may be affected by various forces and vibrations, and this layout can effectively disperse these forces and vibrations, reducing the wear and failure rate of the driving assembly;

[0053] Secondly, placing the driving assembly between the mounting plates 15 is also conducive to improving space utilization. In a limited space, a reasonable layout can enable each component to be arranged compactly and orderly, avoiding waste of space. At the same time, this layout also helps to reduce volume and weight, improving the portability and flexibility of the equipment.

[0054] One end of the magnetic attraction block 7 is connected with a mounting structure for connecting the auxiliary magnetic attraction block 7 and the clamping jaw 2. The mounting structure includes a plug rod 17, a rubber clamping block 18, and a rubber clamping plate 19. The rubber clamping block 18 is in the shape of an arc convex and is located on the outer side of the plug rod 17. The rubber clamping plate 19 is installed at one end of the plug rod 17 and has a diameter larger than that of the plug rod 17;

[0055] The insertion rod 17 serves as the core component for connection, ensuring a firm connection between the magnetic attraction block 7 and the clamping jaw 2. Its design is simple and effective, capable of withstanding and transmitting sufficient force, making the magnetic attraction block 7 not prone to loosening or falling off during operation. The setting of the rubber clamping block 18 increases the friction between the insertion rod 17 and the clamping jaw 2, further improving the connection stability. The rubber material has good elasticity and wear resistance, and can relieve the stress generated by vibration or impact to a certain extent, thus protecting the connection structure from damage;

[0056] Meanwhile, the arc convex design of the rubber clamping block 18 also makes it easier to fit with the contact surface of the clamping jaw 2, improving the connection tightness and stability. The installation of the rubber clamping plate 19 not only increases the diameter of the end of the insertion rod 17, making the connection more firm, but also plays a role in limiting and fixing. The material and shape of the rubber clamping plate 19 are similar to those of the rubber clamping block 18, and it also has good elasticity and wear resistance. During the installation process, the rubber clamping plate 19 can be tightly clamped into the corresponding position of the clamping jaw 2 to prevent the accidental pulling out or loosening of the insertion rod 17.

[0057] A connection structure for mating installation with the installation structure is provided inside the clamping jaw 2. The connection structure includes a connection groove 20, a clamping groove 21, and a limiting groove 22. The shapes and positions of the connection groove 20, the clamping groove 21, and the limiting groove 22 are consistent with the shapes and positions of the insertion rod 17, the rubber clamping block 18, and the rubber clamping plate 19; this design ensures the precise docking and firm connection between the clamping jaw 2 and the installation structure. The insertion rod 17 can be accurately inserted into the connection groove 20 to form a preliminary fixation; the rubber clamping block 18 can be tightly clamped into the clamping groove 21 to increase the tightness and stability of the connection; and the cooperation between the rubber clamping plate 19 and the limiting groove 22 further restricts the lateral movement of the clamping jaw 2 and the magnetic attraction block 7, ensuring that they will not loosen or fall off during operation;

[0058] Secondly, the design of this structure also takes into account the convenience and efficiency of installation. Since the shapes and positions of the components match each other, no complex adjustment and calibration are required during installation. Simply insert the insertion rod 17, the rubber clamping block 18, and the rubber clamping plate 19. During the insertion process, they can be respectively aligned and inserted into the corresponding slots, greatly saving installation time and labor costs; in addition, the use of rubber material also brings additional advantages. Rubber has certain elasticity and toughness, and can absorb and relieve the impact and vibration during the installation process to a certain extent, protecting the clamping jaw 2 and the installation structure from damage. At the same time, the rubber also has good sealing performance, which can prevent impurities such as dust and moisture from entering the connection part and affecting the connection stability and reliability.

[0059] The fixed plate 3 is installed on the surface of the base 1, and both the first movable rod 4 and the second movable rod 5 are connected to the fixed plate 3 through locking screws 23. Adopting this connection method significantly enhances the structural stability. The fixed plate 3 serves as a bridge connecting the base 1, the first movable rod 4, and the second movable rod 5. Its strong structure can effectively disperse and bear the force transmitted from the movable rods, thereby ensuring the stability of the entire device during operation. The locking screws 23, through their limiting function, limit the movable rods on the fixed plate 3, further enhancing the firmness of the connection, preventing the loosening or detachment of the movable rods during use, and at the same time leaving a space for the first movable rod 4 and the second movable rod 5 to rotate, avoiding the first movable rod 4 and the second movable rod 5 being locked on the fixed plate 3, resulting in the inability to drive the jaw 2 to move.

[0060] Secondly, this design provides good adjustment flexibility. Since the first movable rod 4 and the second movable rod 5 are connected to the fixed plate 3 through locking screws 23, the position or angle of the movable rods can be easily adjusted according to needs. This flexibility enables the entire device to adapt to different working scenarios and requirements, improving its versatility and practicality. In addition, this connection method also facilitates the maintenance and replacement of components. When the movable rod or the fixed plate 3 is worn or damaged, the locking screw 23 can be simply loosened to easily remove and replace the new components without large-scale disassembly of the entire device. This not only saves maintenance time and cost but also extends the service life of the device.

[0061] Moreover, from the perspective of cost-effectiveness, this connection method is relatively simple and low-cost. The locking screw 23, as a common fastener, has a relatively low cost and is easily obtainable. At the same time, due to the relatively simple connection structure, the manufacturing and assembly processes are more efficient and economical. While reducing the manufacturing cost, it simplifies the installation process, achieving the effect and function of convenient installation.

[0062] The surface of the jaw 2 is provided with anti-slip lines 24 for increasing the clamping friction, and the anti-slip lines 24 are in a wedge-shaped structure. The wedge-shaped anti-slip lines 24 provided on the surface of the jaw 2 mainly reflect in enhancing the clamping friction and improving the clamping stability. The design of the wedge-shaped structure can increase the roughness of the contact surface, thereby generating greater friction when clamping an object, preventing the object from sliding or moving in the jaw 2. This design is applicable to occasions where stable clamping is required underwater, effectively ensuring the accuracy and safety of clamping. In addition, the wedge-shaped structure also has a certain self-locking function, which can resist external impact forces to a certain extent and further improve the clamping stability.

[0063] The design key points of the present utility model are as follows: This device integrates multiple components such as a base 1, a jaw 2, a movable rod, a retractable gear 6, a commutation component, a driving component, and a magnetic attraction block 7, achieving efficient and flexible grasping of magnetizable metals. The jaw 2 is connected to the base 1 through a first movable rod 4 and a second movable rod 5. This structure is not only stable but also can adjust the opening and closing degree of the jaw 2 according to requirements to adapt to magnetizable metals of different sizes. At the same time, the arc surface design at both ends of the jaw 2 matches the radian of the magnetic attraction block 7, ensuring a tight fit between the magnetic attraction block 7 and the magnetizable metal, and improving the stability and accuracy of grasping.

[0064] The combined use of the retractable gear and the commutation component makes the opening and closing action of the jaw 2 smoother and more precise. The commutation component can assist the retractable gear 6 to achieve the commutation function, thereby controlling the opening and closing direction of the jaw, which is crucial for accurately grasping and releasing magnetizable metals. The driving component provides power support for the entire device, ensuring the smooth progress of various operations.

[0065] The detachable structure design between the magnetic attraction block 7 and the jaw 2 provides convenient space for users. Users can choose whether to install the magnetic attraction block 7 or replace the magnetic attraction block 7 with different magnetic forces according to actual needs to adapt to different types of magnetizable metals. This design increases the flexibility of use.

[0066] The magnetic attraction block 7 adopted in this structure, during underwater operation, since the water pressure exerts pressure on the surface of the magnetic attraction block 7, the connection between the magnetic attraction block 7 and the jaw 2 can be made more stable, reducing the probability of the magnetic attraction block 7 falling off the surface of the jaw 2.
