Description

Technical Field

[0001] This invention relates to the field of monitoring equipment technology, specifically to a smart power grid monitoring device. Background Technology

[0002] A power grid is a general term for a power system composed of power generation, transmission, transformation, distribution, and consumption. Its core function is to realize the production, transmission, distribution, and use of electricity. Among these, the main role of the transmission link is to efficiently and over long distances transmit the electricity generated by power plants to load centers or distribution networks. Long overhead transmission lines are one of the core facilities of the transmission link. As a core component of the power system, the safe and stable operation of long overhead transmission lines is directly related to the reliability of power supply. Suspension clamps, as key hardware of overhead lines, mainly undertake the functions of fixing conductors and transmitting loads. The reliability of their connection with the conductor depends on the preload of the bolts. The mechanical pressure generated by the bolt tightening ensures that the suspension clamps are in close contact with the conductors, maintaining extremely low contact resistance and preventing local overheating caused by poor contact during current transmission.

[0003] Current smart power grid monitoring equipment often encounters long overhead lines where conductor vibration due to wind can cause fatigue and loosening of the bolts or nuts in the suspension clamps. This leads to a decrease in contact pressure and an increase in gap between the clamp and the conductor, resulting in a sharp increase in contact resistance. It is difficult to detect and tighten loose bolts or nuts in real time, which may lead to serious accidents. Secondly, the heat dissipation of nearby equipment (such as transformers and reactors on towers) or high temperatures in hot weather may cause the surface temperature of the suspension clamps to be higher than normal. In this case, the monitoring equipment may make misjudgments, which may lead to over-inspection or missed inspection.

[0004] To address the above issues, a smart power grid monitoring device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a smart power grid monitoring device. By using this device, the problems mentioned above are solved, such as the easy fatigue loosening of the bolts or nuts of the suspension clamps, which leads to a decrease in contact pressure and an increase in gap between the clamp and the conductor, a sharp increase in contact resistance, difficulty in detecting and tightening loose bolts or nuts in real time, and the possibility of misjudgment by the monitoring device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A smart power grid monitoring device includes a clamp body and a conductor installed inside the clamp body. A screw is threaded through one side of the clamp body, and a nut is threaded onto the surface of the screw, with the nut in contact with the clamp body. A housing is fixedly installed at one end of the clamp body, and a pressing member is threaded through one end of the housing. A guide shell is fixedly installed inside the housing, and a moving block is slidably connected inside the guide shell. A distance sensor is embedded in one side of the moving block. Lever pushers are correspondingly installed on both sides of the housing. One end of the lever pusher is slidably connected to the guide shell and in contact with the moving block. A fixing clamp is installed at the other end of the lever pusher, and both fixing clamps are slidably connected to one end of the screw and the surface of the nut. An insulation shell is fixedly installed on one side of the housing, and a heat-conducting member is fixedly installed at one end of the insulation shell, with one end of the heat-conducting member in contact with the surface of the clamp body. An expansion member is installed inside the insulation shell, and an elastic plate is fixedly installed at one end of the expansion member, with the elastic plate slidably connected to the housing and the guide shell. Pressure sensors are installed at one end and one side of the elastic plate. Both the pressure sensor and the distance sensor are electrically connected to the pressing member via a controller.

[0008] Furthermore, the housing has a first sliding groove through both sides, a limiting plate through one side of the housing, and one end of the limiting plate through one side of the guide shell. The elastic plate is slidably connected to the limiting plate. Abutting plates are fixedly installed on both sides of the housing. Both abutting plates are in contact with the wire clamp body. A second sliding groove is through one side of each of the two abutting plates. A first bolt is slidably connected inside the second sliding groove and is threadedly connected to the wire clamp body. Two connecting rings are installed at one end of the housing. L-shaped grooves are correspondingly opened on both sides of the housing. Positioning rods are fixedly installed on both sides of the housing.

[0009] Furthermore, the pressing component includes a cylinder and a pressing block fixed to one end of the cylinder. The cylinder is connected through to one end of the housing, and the pressing block is slidably connected to the guide shell.

[0010] Furthermore, a third sliding groove is provided through both sides of the guide shell.

[0011] Furthermore, a push plate is fixedly installed on one side of the movable block. The push plate is slidably connected to the third slide groove and the first slide groove, and the push plate is in contact with the lever pusher.

[0012] Furthermore, the lever pusher includes a rotating plate and a fourth sliding groove extending through the surface of the rotating plate. The positioning rod is slidably connected to the fourth sliding groove. A support rod is fixedly installed on one side of the rotating plate near its end. An L-shaped plate is installed on one side of the rotating plate and is slidably connected to an L-shaped groove. An inclined groove is extended through one side of the L-shaped plate, and the support rod is slidably connected to the inclined groove. Several first springs are fixedly installed on one side of the L-shaped plate and are fixedly connected to the L-shaped groove. A crossbar is fixedly installed on one side of the L-shaped plate. The crossbar is slidably connected to the first and third sliding grooves, and the pusher plate is in contact with the crossbar. Two contact plates are fixedly installed on both sides of the crossbar. Both contact plates are slidably connected to the guide shell. Three rollers rotate between the two contact plates, and all three rollers are in contact with the third sliding groove.

[0013] Furthermore, a hinge seat is fixedly installed on one side of the fixing clamp, and the hinge seat is rotatably connected to the rotating plate.

[0014] Furthermore, the heat-conducting component includes a heat-conducting block and an L-shaped heat-conducting plate fixed to one side of the heat-conducting block. The heat-conducting block is in contact with the surface of the wire clamp body. An insulation plate is installed on the surface of the L-shaped heat-conducting plate. The L-shaped heat-conducting plate is connected through to one end of the insulation shell. Support plates are fixedly installed on both sides of the insulation plate. Both support plates are in contact with the shell. Two second bolts are connected through to one side of each support plate. Both second bolts are threaded to the shell.

[0015] Furthermore, the expansion member includes a first metal plate and a second metal plate fixed to one side of the first metal plate. The first metal plate is fixedly connected to an L-shaped heat-conducting plate, and guide rods are connected through one side of both the first and second metal plates.

[0016] Furthermore, the elastic plate includes a first sliding plate and several second springs fixedly connected inside one end of the first sliding plate. The first sliding plate is slidably connected to a limiting plate. A connecting plate is slidably connected to one end of the first sliding plate. The connecting plate is fixedly connected to the second springs. A second sliding plate is fixedly installed on one side of the connecting plate. The second sliding plate is slidably connected to the limiting plate. A rectangular block is fixedly installed on one side of the second sliding plate. The rectangular block is slidably connected to the limiting plate. An inclined plate is fixedly installed on one side of the rectangular block.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] When the clamp itself generates heat, the heat is transferred to the expansion component through the heat-conducting component. At this time, the expansion component expands due to heat, which can push the elastic plate to move to the right. The movement of the elastic plate to the right can drive the pressure sensor to move. If the pressure sensor does not move unimpeded, it will not transmit a signal to the controller, and the pressing component will not be activated. Therefore, it can be concluded that the overheating of the clamp body is caused by the heat from sunlight or heat dissipation around the transformer, and not by the increased resistance between the clamp body and the wire caused by the screw or nut being loose.

[0019] When the screw or nut loosens, the lever amplifies the slight tilt of the loosening, causing the moving block to move upwards. Due to the loosening, the gap between the clamp body and the wire increases, increasing the resistance between them. This causes the clamp body to overheat. The heat-conducting component transfers heat to the expansion component, causing it to expand and push the elastic plate to the right. This movement of the elastic plate moves the pressure sensor. When the moving block reaches the restricted position, it prevents the screw or nut from further loosening and separating, thus ensuring pressure transmission. When the sensor contacts the moving block, the controller controls the pressing component to move downwards, pushing the elastic plate to the left and causing the moving block to move downwards to reset. The moving block pushes the fixed clamp, causing the screw and nut to rotate relative to each other, generating axial preload, making the connection or fastening tighter. Therefore, it can monitor the overheating phenomenon caused by the wire and clamp body due to the loosening of the screw or nut, and can also tighten the screw and nut. Thus, it can achieve accurate fault differentiation, and complete the closed-loop process by tightening the screw and nut to ensure the stable operation of long overhead lines.

[0032] 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.

[0033] To address the technical issue of potential misjudgments by monitoring equipment, such as... Figures 1-11 As shown, the following preferred technical solutions are provided:

[0034] like Figures 1-3 and Figure 11As shown, a smart power grid monitoring device includes a clamp body 1 and a conductor 2 installed inside the clamp body 1. The clamp body 1 serves to fix the conductor 2 and transmit loads. A screw 3 is threaded through one side of the clamp body 1, and a nut 4 is threaded onto the surface of the screw 3. The nut 4 is in contact with the clamp body 1. The mechanical pressure generated by the tightening of the screw 3 and the nut 4 ensures a tight contact between the clamp body 1 and the conductor 2, maintaining an extremely low contact resistance, ideally close to the resistance of the conductor 2 itself. This prevents localized overheating due to poor contact during current transmission. One end of the clamp body 1 is fixedly mounted with a housing 5, which is fixed to the pole. A pressing member 6 is connected through one end of the housing 5. A guide shell 7 is fixedly mounted inside the housing 5. A moving block 8 is slidably connected inside the guide shell 7. The force pushed by the pressing member 6 can make the moving block 8 return to its initial position, which can tighten and fix the screw 3 and nut 4. A distance sensor 9 is embedded on one side of the moving block 8. The distance sensor 9 is used to monitor the distance between the moving block 8 and the pressing member 6 in real time, which can ensure that the screw 3 or nut 4 can be corrected in time when it is loose.

[0035] Lever pushers 10 are installed on both sides of the housing 5. One end of the lever pusher 10 is slidably connected to the guide housing 7 and is in contact with the moving block 8. The lever pusher 10 amplifies the slight tilt of the loose screw 3 or nut 4 into the upward movement of the moving block 8, solving the problem of difficulty in detecting slight loosening. A fixing clip 20 is installed on the other end of the lever pusher 10, and the fixing clip 20 is slidably connected to one end of the screw 3 and the surface of the nut 4. When the screw 3 or nut 4 becomes loose, the fixing clip 20 tilts, and the lever pusher 10 amplifies the slight tilt of the loose screw 3 or nut 4 into the upward movement of the moving block 8. The upward movement of the housing 5 is achieved by fixing an insulation shell 30 on one side of the housing 5. A heat-conducting component 40 is fixedly installed at one end of the insulation shell 30, and one end of the heat-conducting component 40 is in contact with the surface of the wire clamp body 1. An expansion component 50 is installed inside the insulation shell 30. The expansion component 50 can expand when heated and contract when cooled. An elastic plate 60 is fixedly installed at one end of the expansion component 50, and the elastic plate 60 is slidably connected to the housing 5 and the guide shell 7. The heat generated on the surface of the wire clamp body 1 is transferred to the expansion component 50 through the heat-conducting component 40. The expansion component 50 expands when heated, which can drive the elastic plate 60 to move. A pressure sensor 70 is installed at one end and one side of the elastic plate 60.

[0036] The pressure sensor 70 and distance sensor 9 work together to more accurately monitor whether the screw 3 or nut 4 is loose. In rainy or snowy weather, the surface of the clamp body 1 may be cold due to the influence of the external environment. When the screw 3 or nut 4 is loose, the fixing clamp 20 tilts. The lever pusher 10 amplifies the slight tilt of the loose screw 3 or nut 4 into the upward movement of the moving block 8. The distance sensor 9 can monitor the distance between the moving block 8 and the lower pressure member 6. The distance sensor 9 is set with a preset threshold to detect when the screw 3 or nut 4 is loose and transmits the signal to the controller. The controller controls the lower pressure member 6 to push the moving block 8 to move, which allows the screw 3 and nut 4 to rotate relative to each other. When the screw 3 and nut 4 rotate relative to each other in the tightening direction of the threads, the threads of the two will gradually mesh and press together, generating axial preload, thus making the connection or fastening state tighter. Both the pressure sensor 70 and the distance sensor 9 are electrically connected to the lower pressure member 6 through the controller.

[0037] In the first scenario: when the clamp body 1 generates heat, the heat-conducting component 40, in contact with the clamp body 1, transfers heat to the expansion component 50. The expansion component 50 expands due to heat, pushing the elastic plate 60 to the right. This movement of the elastic plate 60 to the right causes the pressure sensor 70 to move. If the pressure sensor 70 moves without obstruction, it will not transmit a signal to the controller (not shown in the figure). In this case, the pressing component 6 will not activate. Therefore, it can be concluded that the overheating of the clamp body 1 is caused by sunlight or heat dissipation from around the transformer, and not by the increased resistance between the clamp body 1 and the wire 2 due to the loosening of the screw 3 or nut 4.

[0038] In the second scenario: when screw 3 or nut 4 loosens, screw 3 or nut 4 will tilt relatively, causing the fixing clamp 20 to tilt. The lever pusher 10 amplifies the slight tilt of screw 3 or nut 4, causing the moving block 8 to move upward. Due to the loosening of screw 3 or nut 4, the gap between the clamp body 1 and the wire 2 increases. At this time, the resistance between the clamp body 1 and the wire 2 increases, and the clamp body 1 itself undergoes an overheating reaction. Since the heat-conducting component 40 is in contact with the clamp body 1, the heat-conducting component 40 transfers heat to the expansion component 50. The expansion component 50 expands due to heat, which can push the elastic plate 60 to move to the right. The movement of the elastic plate 60 to the right can drive the pressure sensor 70 to move. At this time, when the moving block 8 moves to the restricted position, it can prevent screw 3 or nut 4 from continuing to loosen and causing separation.

[0039] When the pressure sensor 70 contacts the moving block 8, the pressure sensor 70 transmits a signal to the controller. The controller then controls the pressing member 6 to move downward, pushing the elastic plate 60 to the left and causing the moving block 8 to move downward to reset. The moving block 8 pushes the lever push member 10, which in turn drives the fixing clamp 20 to rotate relative to the screw 3 and nut 4. When the screw 3 and nut 4 rotate relative to each other in the tightening direction of the threads, the threads of the two will gradually mesh and tighten, generating axial preload, thus making the connection or fastening state tighter. Therefore, it can monitor the overheating phenomenon caused by the loosening of the screw 3 or nut 4 between the wire 2 and the clamp body 1, and it can also tighten the screw 3 and nut 4.

[0040] The third scenario: When the clamp body 1 generates heat, the heat-conducting component 40, in contact with the clamp body 1, transfers heat to the expansion component 50. The expansion component 50 expands due to the heat, pushing the elastic plate 60 to the right. This movement of the elastic plate 60 moves the pressure sensor 70. If the pressure sensor 70 moves unimpeded, and simultaneously the screw 3 or nut 4 loosens, it will tilt, causing the clamp 20 to tilt. The lever pusher 10 then corrects this slight tilting of the screw 3 or nut 4. The amplification causes the moving block 8 to move upward. The upward movement of the moving block 8 will squeeze the pressure sensor 70. At this time, the pressure sensor 70 transmits a signal to the controller. The controller then controls the pressing part 6 to move downward, pushing the elastic plate 60 to move to the left, and causing the moving block 8 to move downward to reset. The moving block 8 pushes the lever push part 10 to drive the fixing clamp 20, causing the screw 3 and nut 4 to rotate relative to each other and tighten. Therefore, it is possible to monitor the overheating caused by the clamp body 1 due to environmental influences and the overheating caused by the loosening of the screw 3 or nut 4, which increases the resistance between the clamp body 1 and the wire 2.

[0041] In the fourth scenario, during rainy or snowy weather, the pressure sensor 70 and distance sensor 9 work together to more accurately monitor whether the screw 3 or nut 4 has become loose. During rainy or snowy weather, the surface of the clamp body 1 may experience low temperatures due to environmental factors. If the screw 3 or nut 4 becomes loose, the fixing clamp 20 will tilt. The lever pusher 10 amplifies the slight tilt of the loose screw 3 or nut 4, causing the moving block 8 to move upwards. The distance sensor 9 can monitor the distance between the moving block 8 and the lower pressure member 6. The distance sensor 9 is set with a preset threshold to detect when the screw 3 or nut 4 has become loose, transmitting the signal to the controller. The controller then controls the lower pressure member 6 to push the moving block 8, allowing the screw 3 and nut 4 to rotate relative to each other. When the screw 3 and nut 4 rotate relative to each other in the tightening direction of the threads, their threads gradually mesh and tighten, generating axial preload, thus making the connection or fastening more secure. This ensures the normal operation of long overhead lines and prevents misjudgments by the monitoring equipment.

[0042] like Figures 8-10 As shown, the heat-conducting component 40 includes a heat-conducting block 401 and an L-shaped heat-conducting plate 402 fixed to one side of the heat-conducting block 401. The heat-conducting block 401 is in contact with the surface of the wire clamp body 1. An insulation plate 403 is installed on the surface of the L-shaped heat-conducting plate 402. The insulation plate 403 can insulate the L-shaped heat-conducting plate 402, reducing heat loss during heat conduction. The L-shaped heat-conducting plate 402 is connected to one end of the insulation shell 30. Supports are fixedly installed on both sides of the insulation plate 403. Plate 404, both support plates 404 are in contact with the housing 5. Two second bolts 405 are connected through one side of each support plate 404. The two second bolts 405 are threaded to the housing 5. The support plates 404 are fixed to both sides of the housing 5 by the second bolts 405, which can fix the insulation plate 403 and facilitate disassembly. The heat generated on the surface of the wire clamp body 1 is transferred to the expansion member 50 through the heat conducting block 401 and the L-shaped heat conducting plate 402.

[0043] The expansion member 50 includes a first metal plate 501 and a second metal plate 502 fixed to one side of the first metal plate 501. The first metal plate 501 is fixedly connected to the L-shaped heat-conducting plate 402. Guide rods 503 are connected through one side of both the first metal plate 501 and the second metal plate 502. One end of both the first metal plate 501 and the second metal plate 502 is a bent structure. The first metal plate 501 and the second metal plate 502 are made of two metals with significantly different coefficients of thermal expansion, such as copper with high CTE and steel with low CTE, through rolling or welding. When the first metal plate 501 is heated and expands, it will drive the second metal plate 502 to bend to the right. At this time, it will push the guide rod 503 to move to the right. The guide rod 503 can push the elastic plate 60 to move to the right. When the first metal plate 501 and the second metal plate 502 cool and shrink, they can drive the guide rod 503 back to the initial position.

[0044] The elastic plate 60 includes a first sliding plate 601 and several second springs 602 fixedly connected inside one end of the first sliding plate 601. The first sliding plate 601 is slidably connected to the limiting plate 52. A connecting plate 603 is slidably connected to one end of the first sliding plate 601. The connecting plate 603 is fixedly connected to the second springs 602. A second sliding plate 604 is fixedly installed on one side of the connecting plate 603. The second sliding plate 604 is slidably connected to the limiting plate 52. A rectangular block 605 is fixedly installed on one side of the second sliding plate 604. The rectangular block 605 is slidably connected to the limiting plate 52. A sloping plate 606 is fixedly installed on one side of the rectangular block 605.

[0045] When the pressure sensor 70 contacts the moving block 8, the output end of the cylinder 61 pushes the lower pressure block 62 to move downward inside the guide shell 7. At this time, the continuous movement of the lower pressure block 62 can push the inclined plate 606 to move the second slide plate 604 and the pressure sensor 70 to the left. At this time, the second spring 602 will be squeezed. Since the second slide plate 604 extends from one end of the inclined plate 606, the inclined plate 606 will only abut against the surface of the lower pressure block 62, and the pressure sensor 70 will not contact the lower pressure block 62.

[0046] To solve the technical problem of not being able to immediately tighten and fix the screw 3 and nut 4, such as Figures 3-5 As shown, the following preferred technical solutions are provided:

[0047] The housing 5 has first sliding grooves 51 extending through both sides. A limiting plate 52 is connected through one side of the housing 5, and one end of the limiting plate 52 is connected through one side of the guide housing 7. The elastic plate 60 is slidably connected to the limiting plate 52. The limiting plate 52 can limit the movement of the elastic plate 60, so that the elastic plate 60 can always be in a lateral movement state. The housing 5 has two abutting plates 53 fixedly installed on both sides. Both abutting plates 53 are in contact with the wire clamp body 1. A second sliding groove 54 is extended through one side of each abutting plate 53. A first bolt 55 is slidably connected inside the second sliding groove 54. The first bolt 55 is threadedly connected to the clamp body 1. The housing 5 can be fixed to one end of the clamp body 1 by the two first bolts 55, which also facilitates disassembly. The first bolt 55 can move inside the second slide groove 54, which can drive the abutment plate 53 to move, and the housing 5 can be fixed in different positions to improve applicability. Two connecting rings 56 are installed at one end of the housing 5. L-shaped grooves 57 are opened on both sides of the housing 5. Positioning rods 58 are fixedly installed on both sides of the housing 5. The two connecting rings 56 can be fixed to the poles and towers of long overhead lines.

[0048] The pressing component 6 includes a cylinder 61 and a pressing block 62 fixed to one end of the cylinder 61. The cylinder 61 is connected through to one end of the housing 5. The pressing block 62 is slidably connected to the guide housing 7. The controller controls the output end of the cylinder 61 to push the pressing block 62 to move inside the guide housing 7. The downward movement of the pressing block 62 can push the moving block 8 to move. Furthermore, the side of one end of the pressing block 62 adopts an arc edge design, which can reduce the degree of wear. The guide housing 7 has a third sliding groove 71 through on both sides. The third sliding groove 71 can limit the movement of the moving block 8, so that the moving block 8 can only move up and down.

[0049] A push plate 81 is fixedly installed on one side of the movable block 8. The push plate 81 is slidably connected to the third slide groove 71 and the first slide groove 51. The push plate 81 is in contact with the lever push member 10. When the movable block 8 moves downward, the push plate 81 increases the contact area with the lever push member 10, which makes the lever push member 10 bear force evenly and can better tighten and fix the screw 3 and nut 4.

[0050] like Figures 4-6As shown, the lever pusher 10 includes a rotating plate 101 and a fourth sliding groove 102 extending through the surface of the rotating plate 101. A positioning rod 58 is slidably connected to the fourth sliding groove 102. A support rod 1011 is fixedly installed on the side of the rotating plate 101 near its end. An L-shaped plate 103 is installed on one side of the rotating plate 101, and the L-shaped plate 103 is slidably connected to an L-shaped groove 57. The L-shaped plate 103 is kept within the L-shaped groove 57 for limiting its movement. An inclined groove 104 extends through one side of the L-shaped plate 103, and the support rod 1011 is slidably connected to the inclined groove 104. Several first springs 1 are fixedly installed on one side of the L-shaped plate 103. 05. The first spring 105 can connect and provide elastic force, and can reset the L-shaped plate 103. The first spring 105 is fixedly connected to the L-shaped groove 57. A crossbar 106 is fixedly installed on one side of the L-shaped plate 103. The crossbar 106 is slidably connected to the first slide groove 51 and the third slide groove 71. The push plate 81 is in contact with the crossbar 106. Two contact plates 107 are fixedly installed on both sides of the crossbar 106. The two contact plates 107 are slidably connected to the guide shell 7. Three rollers 108 rotate between the two contact plates 107. The three rollers 108 are in contact with the third slide groove 71.

[0051] The roller 108 reduces friction with the third slide groove 71, allowing the crossbar 106 to move more easily. When the screw 3 or nut 4 loosens, it tilts relative to the ground, causing the fixing clamp 20 to tilt to the left. At this time, the rotating plate 101 rotates and moves upward. The L-shaped plate 103 moves upward through the cooperation of the support rod 1011 and the tilting groove 104. Since the length from the connecting end of the rotating plate 101 and the L-shaped plate 103 to the positioning rod 58 is greater than the length from the connecting end of the fixing clamp 20 and the connecting end of the rotating plate 101 to the positioning rod 58, the L-shaped plate 103 moves upward. Therefore, the slight tilt of the loose screw 3 or nut 4 amplifies the upward movement of the moving block 8. When the output end of the cylinder 61 pushes the lower pressure block 62 to move inside the guide shell 7, the downward movement of the lower pressure block 62 can push the moving block 8 to move. The push plate 81 pushes the L-shaped plate 103 to move downward. Therefore, the rotating plate 101 drives the fixing clamp 20 to reset. When the screw 3 and nut 4 rotate relative to each other in the tightening direction of the threads, the threads of the two will gradually mesh and press together, generating axial preload, thereby making the connection or fastening state tighter.

[0052] A hinge seat 201 is fixedly installed on one side of the fixed clamp 20. The hinge seat 201 is rotatably connected to the rotating plate 101. The hinge seat 201 connects the fixed clamp 20 and the rotating plate 101, so that the rotating plate 101 can rotate and move when the fixed clamp 20 is tilted.
