[0033] The invention provides a clamp for hoisting a battery.

[0034] Reference Figure 1 to Figure 3 In an embodiment of the present invention, a clamp for hoisting a battery includes:

[0035] A frame 10, wherein the frame 10 includes a first bracket 11 and a second bracket 12 which are arranged opposite to each other;

[0036] The clamping mechanism 20 includes a guide assembly 21, a first clamping assembly 22, and a second clamping assembly 23 arranged opposite to the first clamping assembly 22. The first clamping assembly 22 and the second clamping assembly 23 are slidably connected to the guide assembly 21. The two ends of the guide assembly 21 are respectively connected to the first bracket 11 and the second bracket 12. The first clamping assembly 22 and the second clamping assembly 23 can move toward or away from each other along the guide assembly 21 to clamp or release the battery.

[0037] The transmission assembly 30 is disposed on the first bracket 11 and the second bracket 12. The transmission assembly 30 is transmission-connected to the first clamping assembly 22 and the second clamping assembly 23. The transmission assembly 30 is used to drive the first clamping assembly 22 and the second clamping assembly 23 to move toward or away from each other to clamp or release the battery.

[0038] This scheme describes a clamp for hoisting batteries, the main purpose of which is to safely and efficiently clamp and move batteries by mechanical means. It mainly consists of three parts: a frame 10, a clamping mechanism 20 and a transmission assembly 30. The frame 10 is the basic supporting structure of the entire device, and it includes two first brackets 11 and second brackets 12 arranged opposite to each other. A certain distance is maintained between the two brackets to provide an installation position for the clamping mechanism 30. The frame 10 not only supports the entire device, but also serves as an interface for connecting external lifting equipment (such as a crane hook) to ensure that the entire device can move stably during the hoisting process. Guide assembly 21 This is a slide rail system or guide rod, and its two ends are respectively fixed to the first bracket 11 and the second bracket 12. The function of the guide assembly 21 is to provide a path for the first clamping assembly 22 and the second clamping assembly 23 to move along a straight line. The first clamping assembly 22 and the second clamping assembly 23 are arranged symmetrically, and they can move toward or away from each other along the guide assembly 21. When the battery needs to be clamped, the two groups of clamping assemblies will move closer to each other; and when the battery needs to be released, they will separate. The design of the clamping assembly should take into account the protection of the battery surface to avoid damage. The transmission assembly 30 is arranged between the first bracket 11 and the second bracket 12. The transmission assembly 30 is responsible for transmitting power to the first clamping assembly 22 and the second clamping assembly 23 so that they can move in a predetermined manner. This is usually achieved by mechanical means such as motor-driven gears, chains, belts, etc. Specifically, the entire device is first moved above the battery to be hoisted or to an appropriate position. The transmission assembly 30 is used to drive the first clamping assembly 22 and the second clamping assembly 23 to move toward each other along the guide assembly 21 until a space suitable for clamping the target battery is formed between the two. Continue to control the two clamping assemblies to move closer through the transmission assembly 30 until they fit tightly on both sides of the battery, thereby achieving safe fixation of the battery. After clamping is completed, an external lifting device (such as a crane) can be connected to the frame 10 to smoothly lift and transfer the battery to a designated location. After reaching the destination, the transmission assembly 30 is operated in reverse to separate the two clamping assemblies, thereby releasing the battery. The double-sided clamping method adopted in this solution increases the grasping stability, reduces the risks caused by single-point suspension, and improves the safety of operation. By adjusting the distance between the clamping assemblies, the device can handle batteries of different sizes. Mechanized operation improves work efficiency and reduces labor costs. The guide assembly 20 ensures accuracy during the clamping process and helps prevent damage to the battery.

[0039] Furthermore, the rack 10 is also provided with a plurality of lifting rings, which are arranged at intervals on the rack for allowing a lifting rope to pass through. An external lifting device (such as a crane) can be used to connect to the lifting rope to smoothly lift and transfer the battery to a designated location.

[0040] Reference Figure 1 to Figure 3In an embodiment of the present invention, the clamp also includes a connecting component 40, and the connecting component 40 includes a first connecting member 41 and a second connecting member 42. The first connecting member 41 is extended along the length direction of the first bracket 11 and is arranged on the first bracket 11, and the second connecting member 42 is extended along the length direction of the second bracket 12 and is arranged on the second bracket 12. The first clamping component 22 is connected to the first connecting member 41, and the second clamping component 23 is connected to the second connecting member 42. The transmission component 30 is transmission-connected to the first connecting member 41 and the second connecting member 42, so that the first connecting member 41 and the second connecting member 42 can move toward each other or move away from each other, so as to drive the first clamping component 22 and the second clamping component 23 to move toward each other or move away from each other along the guide component 21.

[0041] The connecting assembly 40 includes a first connecting member 41 and a second connecting member 42. The first connecting member 41 is fixed on the first bracket 11 and extends along its length direction, and is used to connect the first clamping assembly 22. The second connecting member 42 is fixed on the second bracket 12 and extends along its length direction, and is used to connect the second clamping assembly 23. The design of the first connecting member 41 and the second connecting member 42 allows them to move toward or away from each other with the action of the transmission assembly 30, thereby driving the corresponding clamping assembly to move. The transmission assembly 30 is arranged between the first bracket 11 and the second bracket 12. The transmission assembly 30 is directly connected to the first connecting member 41 and the second connecting member 42, and drives the connecting member and the clamping assembly connected thereto to move through a mechanical transmission method (such as a gear, a chain, etc.). By introducing the connecting assembly 40, the stability of the clamping assembly during the movement is ensured, and the deviation that may be caused by relying solely on the guide assembly is reduced. The connecting assembly 40 is directly connected to the transmission assembly 30, and can transmit power more accurately, thereby improving the accuracy of the clamping action. Due to the flexible design of the connecting member, it can adapt to batteries of different sizes by adjusting its length, thereby increasing the scope of application of the device. The clear functional division between the components is also conducive to quickly locating the problem during later maintenance. It is understandable that the connector can be a slider connector, each connector can be designed as a slider, which is mounted on the bracket and can slide along the guide rail or groove on the bracket; or the connector can be a section of rack, which meshes with the gear in the transmission assembly. When the gear rotates, the rack moves in a straight line; or the connector can be a nut mounted on a fixed screw. One end of the screw is connected to the transmission assembly, such as a motor, and the nut is driven to move axially by rotating the screw. In this embodiment, preferably, the connector is a rigid rod-shaped structure extending along the length of the bracket. This design can provide stability and strength while ensuring that the clamping assembly can move accurately along a predetermined path. One end of the connector is fixed to the bracket and the other end is connected to the clamping assembly. The fixing point may be achieved by welding, bolting or other mechanical fastening methods. The long rod serves as a force transmission medium to transmit the power generated by the transmission assembly 30 to the clamping assemblies 22 and 23, so that they can move toward or away from each other. Although the main guiding function is provided by the guide assembly 21, the long rod itself can also play a certain auxiliary guiding role, especially maintaining its linear motion when the clamping assembly is subjected to lateral forces. Because the long rod is rigid, it helps to reduce shaking during the clamping process and improve the stability of the entire system. The length of the long rod can be adjusted as needed to accommodate batteries of different sizes.

[0042] Reference Figure 1 to Figure 3In an embodiment of the present invention, the transmission assembly 30 includes a first lever body 31 with opposite thread rotation directions and a second lever body 32 connected to the first lever body 31, the other end of the first lever body 31 is connected to the first bracket 11, and the other end of the second lever body 32 is connected to the second bracket 12.

[0043] One end of the first lever body 31 is connected to the first bracket 11, and the other end is connected to the second lever body 32. The first lever body 31 has a left-handed thread. One end of the second lever body 32 is connected to the second bracket 12, and the other end is connected to the first lever body 31. The second lever body 32 has a right-handed thread. The two lever bodies are connected together by a gear or other mechanical device in the middle to ensure that they can rotate at the same time but in opposite directions. The first connecting member 41 and the second connecting member 42 are respectively fixed to the first lever body 31 and the second lever body 32 by nuts, and these nuts are matched with the threads on the respective lever bodies. Specifically, the first lever body 31 and the second lever body 32 are driven to rotate by a motor or other power source. Since the threads of the two are opposite in rotation, when the first lever body 31 rotates clockwise, the second lever body 32 rotates counterclockwise, and vice versa. When the first lever body 31 and the second lever body 32 rotate, the nut will move along the lever body. Since the threads are opposite in rotation, the two nuts will move toward each other, driving the first connecting member 41 and the second connecting member 42 to move toward each other. The movement of the first connecting member 41 and the second connecting member 42 further drives the first clamping assembly 22 and the second clamping assembly 23 to move toward each other until the battery is tightly clamped. Use an external lifting device connected to the top of the frame 10 to smoothly lift the battery and transfer it to the designated location. After arriving at the destination, reverse the transmission assembly 30 to rotate the first lever body 31 and the second lever body 32 in the opposite direction, so that the clamping assembly is separated and the battery is safely lowered. Very precise linear motion control can be achieved using threaded transmission, which is very important for applications that require fine adjustment. The two lever bodies are driven simultaneously by a common drive shaft, which ensures that the two clamping assemblies can move toward or away from each other synchronously, thereby improving the stability and reliability of the clamping. Compared with complex multi-component systems, this design is simpler, reduces failure points, and improves the reliability and maintenance convenience of the system. The clamping force and stroke can be adjusted by changing the thread pitch or the design of the nut to adapt to batteries of different sizes and weights. Synchronous clamping and loosening actions can be completed quickly, improving work efficiency. It is understandable that the first bar body 31 and the second bar body 32 have threads with different rotation directions, respectively (for example, the first bar body 31 is a left-handed thread, and the second bar body 32 is a right-handed thread). One end of each connecting member 40 has an internal threaded hole, which cooperates with the external thread on the corresponding bar body. The internal threaded hole of the first connecting member 41 is engaged with the left-handed thread of the first bar body 31, and the internal threaded hole of the second connecting member 42 is engaged with the right-handed thread of the second bar body 32. Further, the first bar body 31 is supported on the first connecting member 41 through the first guide seat, further providing sufficient strength for the installation of the first bar body 31, and the second bar body 32 is supported on the second connecting member 42 through the second guide seat, further providing sufficient strength for the installation of the second bar body 32. The first guide seat and the second guide seat not only fix the positions of the first bar body 31 and the second bar body 32, but also bear the role of distributing the load-bearing of the first bar body 31 and the second bar body 32 to the frame 10, thereby ensuring the stability of the entire system.The first guide seat and the second guide seat are connected and installed on the frame 10 by means of bolts and nuts.

[0044] Reference Figure 1 to Figure 3 In the embodiment of the present invention, the transmission assembly 30 also includes a locking assembly 33, and the locking assembly 33 includes a locking seat 331, a locking bolt and a locking handle 332. The locking seat 331 is connected to the first lever body 31 through the locking bolt, and the locking handle 332 is connected to the locking seat 331. The locking handle 332 can enable the locking seat 331 to have a position locked with the first lever body 31 and a position unlocked with the first lever body 31.

[0045] In addition to the first lever body 31 and the second lever body 32, the transmission assembly 30 also includes a locking assembly 33. The main function of this locking assembly 33 is to lock the position of the first lever body 31 after clamping the battery to prevent the clamping from loosening due to vibration or other external forces during transportation. When the first lever body 31 and the second lever body 32 rotate, the first connecting member 41 and the second connecting member 42 will move toward each other, driving the first clamping assembly 22 and the second clamping assembly 23 to move toward each other until the battery is tightly clamped. Once the battery is clamped, the operator can use the locking handle 332 to lock the locking seat 331 with the first lever body 31. The specific operation is to tighten the locking bolt by rotating the locking handle 332, thereby fixing the locking seat 331 at the current position of the first lever body 31. Use an external lifting device connected to the top of the rack 10 to smoothly lift the battery and transfer it to the designated location. After arriving at the destination, first reverse the locking handle 332 to release the locking state between the locking seat 331 and the first lever body 31. Then, the transmission assembly 30 is operated in reverse to rotate the first bar body 31 and the second bar body 32 in the opposite direction, so that the clamping assembly is separated and the battery is safely put down. The locking assembly 33 is used to lock the position of the bar body after clamping the battery, ensuring that the clamping will not be loosened due to vibration or other external forces during transportation, thereby improving the overall safety. The locking mechanism can provide additional support to prevent the clamping assembly from accidentally moving during transportation. It is understandable that when the locking position is locked, when the locking handle 332 is operated to a certain position, a tight connection is formed between the locking seat 331 and the first bar body 31, so that the first bar body 31 cannot move relative to the locking seat 331. The implementation method can be threaded locking. When the locking handle 332 rotates, the locking seat 331 is pressed against the first bar body 31 through the thread, generating sufficient friction or mechanical clamping force to prevent it from moving; it can also be wedge locking. The locking handle 332 pushes a wedge block to make it in close contact with the first bar body 31, and the friction is increased through the inclined surface of the wedge block to achieve a locking effect. In the unlocked position, when the locking handle 332 is operated to another specific position, the connection between the locking seat 331 and the first lever body 31 is loosened, allowing the first lever body 31 to move freely relative to the locking seat 331. The implementation method can be thread locking, reverse rotation of the locking handle 332 to loosen the threaded connection between the locking seat 331 and the first lever body 31, reducing friction or mechanical clamping force; or wedge locking, reverse operation of the locking handle 332 to loosen the wedge block and reduce the contact pressure with the first lever body 31.

[0046] Reference Figure 1 to Figure 3 In an embodiment of the present invention, the clamp further includes a handwheel assembly 50, and the handwheel assembly 50 includes a handwheel 51 and a handle 52. The handwheel 51 is provided at one end of the first lever body 31, and the handle 52 is rotatably mounted on the handwheel 51.

[0047] This design allows the operator to drive the first lever body 31 and the second lever body 32 by manually rotating the handle 52, thereby realizing the movement of the clamping assembly toward or away from each other. The handwheel assembly 50 allows the operator to easily control the movement of the clamping assembly by manually rotating the handle 52 without relying on an electric or pneumatic system. Through manual operation, the operator can feel the clamping force more intuitively and avoid accidents caused by failures of the automation system. The handwheel assembly 50 is suitable for occasions where there is no power supply or air source, which increases the scope of application of the system. The mechanical structure of manual operation is relatively simple and easy to maintain and inspect.

[0048] Reference Figure 1 to Figure 3 In the embodiment of the present invention, the guide assembly 21 includes a first guide member 211 and a second guide member 212 spaced apart from the first guide member 211, both ends of the first guide member 211 and the second guide member 212 are respectively connected to the first bracket 11 and the second bracket 12, the first clamping assembly 22 includes a first clamping member 221 and a second clamping member 222, the second clamping assembly 23 includes a third clamping member 231 and a fourth clamping member 232, the first clamping member 221 and the second clamping member 222 are spaced apart from each other along the length direction of the first connecting member 41. On the first connecting member 41, the third clamping member 231 and the fourth clamping member 232 are arranged on the second connecting member 42 at intervals along the length direction of the second connecting member 42, the first clamping member 221 and the third clamping member 231 are transmission-connected to the first guide member 211, the second clamping member 222 and the fourth clamping member 232 are transmission-connected to the second guide member 212, and an accommodating space is constructed between the first clamping member 221, the second clamping member 222, the third clamping member 231 and the fourth clamping member 232, and the accommodating space is used to place batteries.

[0049] When the first bar body 31 and the second bar body 32 rotate, the first connecting member 41 and the second connecting member 42 will move toward each other. The first clamping member 221 and the second clamping member 222 on the first connecting member 41, and the third clamping member 231 and the fourth clamping member 232 on the second connecting member 42, respectively move toward each other along the first guide member 211 and the second guide member 212. The accommodation space between the first clamping member 221 and the third clamping member 231, and the second clamping member 222 and the fourth clamping member 232 gradually decreases until the battery is tightly clamped. Once the battery is clamped, the operator uses the locking handle 332 to lock the locking seat 331 with the first bar body 31 to prevent it from loosening during transportation. Use an external lifting device connected to the top of the rack 10 to smoothly lift the battery and transfer it to the designated location. After arriving at the destination, first reversely operate the locking handle 332 to release the locking state between the locking seat 331 and the first bar body 31. Then, the transmission assembly 30 is operated in reverse to rotate the first lever body 31 and the second lever body 32 in the opposite direction, so that the clamping assembly is separated and the battery is safely put down. The four clamping members (the first clamping member 221, the second clamping member 222, the third clamping member 231 and the fourth clamping member 232) are guided by two guide members (the first guide member 211 and the second guide member 212) to ensure linear motion and stability during the clamping process. The design of multiple clamping members can distribute the clamping force more evenly, reduce local pressure on the battery, and protect the battery surface. By adjusting the relative position of the first connecting member 41 and the second connecting member 42, batteries of different sizes can be adapted. The clear functional division between the components is also conducive to quickly locating the problem during later maintenance. A stable clamping surface is formed by four clamping members, which can better fix the battery, especially when handling larger or heavier batteries. It is understandable that the guide member can be a linear guide composed of a guide rail and a slider. The guide rail is fixed on the bracket, and the slider is mounted on the clamping member, which can slide along the guide rail in a straight line direction; it can also be a sliding rod, which is composed of a smooth metal rod (usually steel or stainless steel) and a matching linear bearing. The linear bearing is mounted on the clamping member and slides along the metal rod; it can also be a linear shaft, which is composed of a linear shaft and a matching linear bearing. The linear bearing is mounted on the clamping member and slides along the linear shaft; it can also be a sliding bearing, which is composed of a guide rail and a sliding bearing. The sliding bearing is mounted on the clamping member and slides along the guide rail. It is understood that the clamping member can be a clamping jaw type, which is usually composed of two or more movable arms that can move toward each other to clamp the object. The opening and closing degree of the clamping jaw can be adjusted to accommodate batteries of different sizes. By accurately controlling the movement of the clamping jaw, high-precision clamping can be achieved. The inside of the clamping jaw can be covered with a soft material (such as rubber or polyurethane) to prevent scratching the battery surface; it can also be a suction cup clamp that uses a vacuum suction cup to absorb the battery surface.

[0050] Reference Figure 1 to Figure 3In the embodiment of the present invention, the clamp also includes a limit assembly 60, and the limit assembly 60 includes a first limit member 61, a second limit member 62, a third limit member 63 and a fourth limit member 64. The first limit member 61 is arranged on the first clamping member 221, the second limit member 62 is arranged on the second clamping member 222, the third limit member 63 is arranged on the third clamping member 231, and the fourth limit member 64 is arranged on the fourth clamping member 232. The first limit member 61, the second limit member 62, the third limit member 63 and the fourth limit member 64 enclose the limit space.

[0051] The limiting assembly 60 includes four limiting members (a first limiting member 61, a second limiting member 62, a third limiting member 63 and a fourth limiting member 64), which are respectively mounted on four clamping members. The limiting space formed by the four limiting members ensures that the battery will not move or fall off during the clamping process, thereby improving the overall stability. A stable clamping surface and limiting space are formed by four clamping members and four limiting members, which can better fix the battery, especially when handling larger or heavier batteries. The limiting assembly 60 further enhances the stability of the clamping and ensures that the battery always remains in the correct position during the entire handling process. It can be understood that the limiting member can be a fixed baffle, which is made of a rigid material (such as a metal plate) and is mounted on the clamping member; it can also be an adjustable baffle, which is composed of a baffle with an adjustable position, usually adjusted by a bolt or a sliding mechanism.

[0052] Reference Figure 1 to Figure 3 In the embodiment of the present invention, the first limiting member 61 includes a first mounting portion 611 and a first limiting portion 612. The first mounting portion 611 is extended along the length direction of the first connecting member 41. The first mounting portion 611 is connected to the first limiting portion 612 and the first clamping member 221 respectively.

[0053] The second position-limiting member 62 includes a second mounting portion 621 and a second position-limiting portion 622. The second mounting portion 621 is extended along the length direction of the first connecting member 41. The second mounting portion 621 is connected to the second position-limiting portion 622 and the second clamping member 222 respectively.

[0054] The third limiting member 63 includes a third mounting portion 631 and a third limiting portion 632. The third mounting portion 631 is extended along the length direction of the second connecting member 42. The third mounting portion 631 is connected to the third limiting portion 632 and the third clamping member 231 respectively.

[0055] The fourth position-limiting member 64 includes a fourth mounting portion 641 and a fourth position-limiting portion 642. The fourth mounting portion 641 is extended along the length direction of the second connecting member 42. The fourth mounting portion 641 is connected to the fourth position-limiting portion 642 and the fourth clamping member 232 respectively.

[0056] The first limiting portion 612 , the second limiting portion 622 , the third limiting portion 632 , and the fourth limiting portion 642 together form the limiting space.

[0057] The limiting assembly 60 includes four limiting members (a first limiting member 61, a second limiting member 62, a third limiting member 63 and a fourth limiting member 64), each of which is composed of a mounting portion and a limiting portion. These limiting members are respectively installed on the four clamping members, and a limiting space is formed by the limiting portion to ensure that the battery is safely fixed in a limited space during the clamping process. This design can further improve the stability and safety of the clamping and prevent the battery from moving or falling off during transportation. It is understood that the mounting portion can be a plate-like structure, consisting of one or more metal plates, usually fixed to the connecting member by bolts, welding or other fastening methods; it can also be a sliding structure, consisting of a slide rail and a slider, and the slider can move on the slide rail to adjust the position of the mounting portion. It is understood that the limiting portion can be a fixed baffle, a fixed baffle made of a rigid material (such as a metal plate) and installed on the mounting portion; it can also be an elastic baffle, a baffle made of a material with a certain elasticity (such as a spring steel sheet or an elastic plastic). The elastic baffle can automatically adapt to batteries of different sizes and provide a certain buffering effect.

[0058] Reference Figure 1 to Figure 3 In the embodiment of the present invention, the first mounting portion 611, the second mounting portion 621, the third mounting portion 631 and the fourth mounting portion 641 are provided with mounting holes corresponding to the first clamping member 221, the second clamping member 222, the third clamping member 231 and the fourth clamping member 232, and the clamp also includes a fastener, which is passed through the mounting holes to lock the first mounting portion 611, the second mounting portion 621, the third mounting portion 631 and the fourth mounting portion 641 with the first clamping member 221, the second clamping member 222, the third clamping member 231 and the fourth clamping member 232 one by one.

[0059] The mounting portion of the limiter is firmly connected to the clamping member by fasteners to ensure that it will not loosen or fall off during clamping and handling. The firm connection between the limiter and the clamping member can prevent the battery from loosening due to vibration or other external forces during transportation, increasing the safety of the system. It is understood that the fastener can be a bolt and nut, consisting of a bolt (usually with threads) and a matching nut; or it can be a screw, a single screw directly screwed into the mounting hole.

[0060] Reference Figure 1 to Figure 3 In the embodiment of the present invention, the cross-sections of the first clamping member 221, the second clamping member 222, the third clamping member 231 and the fourth clamping member 232 are all "L" shaped.

[0061] The L-shaped cross section can provide two contact surfaces (horizontal and vertical), thereby increasing the contact area with the battery surface. This helps to distribute the clamping force more evenly, reduce local pressure, and improve the stability of the clamping. The L-shaped structure can better clamp the edge of the battery to prevent the battery from sliding or falling off due to vibration or other external forces during transportation. It can be understood that the first clamp 221 and the second clamp 222 are respectively located on one side of the battery, the horizontal part of the L-shape supports the bottom of the battery, and the vertical part fits the side of the battery. The third clamp 231 and the fourth clamp 232 are located on the other side of the battery, and the bottom of the battery is also supported by the horizontal part of the L-shape, and the vertical part fits the other side of the battery. Designing the cross section of the clamp to be "L" shaped can provide better clamping stability, support, and facilitate installation and adjustment. This design can also protect the battery surface, reduce damage, and simplify the manufacturing and maintenance process.

[0062] Reference Figure 1 to Figure 3 In the embodiment of the present invention, the first clamping member 221, the second clamping member 222, the third clamping member 231 and the fourth clamping member 232 are all provided with a plurality of through holes.

[0063] The first clamp 221 and the second clamp 222 are provided with a plurality of through holes, which can be used to fix the clamp to the connecting member by bolts, and can also be used to install the limiter. The third clamp 231 and the fourth clamp 232 are also provided with a plurality of through holes, which can be used to fine-tune the position of the clamp to adapt to batteries of different sizes. By providing through holes on the clamp, the weight of the clamp can be significantly reduced. This is particularly important for applications that require frequent movement or lifting, because lighter clamps can reduce the labor intensity of the operator and improve handling efficiency. Providing through holes can also reduce the amount of material used, thereby reducing manufacturing costs. Through holes can be used to install different fasteners (such as bolts, pins, etc.), thereby allowing the position of the clamp to be fine-tuned. This enables the fixture to adapt to batteries of different sizes and shapes. Multiple through holes provide multiple fixing points, and a suitable fixing position can be selected according to actual needs to improve the stability and reliability of the clamp.
