[0054] Reference Figure 1 and Figure 2As shown, this embodiment provides a clamping fixture, which includes a first bracket 100, a second bracket 200, and a clamping assembly 300. The first bracket 100 and the second bracket 200 are rotatably connected. The clamping assembly 300 includes a clamping bracket 310, a fixed clamping plate 320, a clamping drive member 330, and a movable clamping plate 340. The clamping bracket 310 is rotatably mounted on the second bracket 200, and the rotation direction of the clamping bracket 310 is perpendicular to the rotation direction of the second bracket 200. The fixed clamping plate 320 and the clamping drive member 330 are both mounted on the clamping bracket 310, and the clamping drive member 330 is connected to the movable clamping plate 340. The clamping drive member 330 drives the movable clamping plate 340 to move and press the plate to be transferred (not shown) onto the fixed clamping plate 320.

[0055] When the clamping fixture needs to clamp the board to be transferred (e.g., copper busbar) and adjust the angle, firstly, the angles of the second bracket 200 and the clamping bracket 310 are adjusted so that the board to be transferred is located between the fixed clamping plate 320 and the movable clamping plate 340; then, the clamping drive 330 is controlled to drive the movable clamping plate 340 to move and press the board to be transferred onto the fixed clamping plate 320, which is suitable for clamping boards of different thicknesses. Both the movable clamping plate 340 and the fixed clamping plate 320 have a large contact area with the board to be transferred, making the clamping of the board to be transferred by the movable clamping plate 340 and the fixed clamping plate 320 stable and reliable; finally, the angles of the second bracket 200 and the clamping bracket 310 are adjusted so that the board to be transferred is suitable for subsequent operations (e.g., fastening the copper busbar into the cabinet of the switch cabinet), which helps to reduce manpower and save effort, and shortens the time.

[0056] In some embodiments, the rotation direction of the clamping bracket 310 is set to the horizontal direction, and the rotation direction of the second bracket 200 is set to the vertical direction. For example, before installation, the copper busbar is placed horizontally, in other words, its length extends horizontally; after installation, the copper busbar is placed vertically, in other words, its length extends vertically. After the clamping assembly 300 clamps the horizontally placed copper busbar, the second bracket 200 can be rotated first to disengage the copper busbar from the fixture or tray; then the clamping bracket 310 is rotated 90° to place the copper busbar vertically, and the second bracket 200 is rotated to transfer the copper busbar into the switch cabinet.

[0057] In one feasible implementation, the first bracket 100 includes a first rod portion 110 and a second rod portion 120 arranged at an angle. The second rod portion 120 is rotatably connected to the second bracket 200. For example, the end of the second rod portion 120 away from the first rod portion 110 is rotatably connected to the second bracket 200. In this embodiment, the first bracket 100 is composed of the first rod portion 110 and the second rod portion 120, which is beneficial for the clamping assembly 300 to maintain a suitable height and for the clamping fixture to transfer the plate to be installed into the cabinet, such as the cabinet of a switch cabinet.

[0058] For example, the length direction of the first rod portion 110 can be extended in the vertical direction, and the length direction of the second rod portion 120 can be extended in the horizontal direction.

[0059] For example, the first support 100 can be a rectangular tube.

[0060] In one feasible implementation, the second support 200 includes a straight rod portion 210, the first end of which is rotatably connected to the second rod portion 120, and the second end of which is rotatably connected to the clamping support 310. The structure is compact and helps to reduce the risk of interference between the second support 200 and the cabinet.

[0061] For example, the length direction of the straight rod portion 210 can extend in the horizontal direction.

[0062] For example, the straight rod portion 210 can be configured as a rectangular tube.

[0063] In one feasible embodiment, the clamping fixture further includes a first rotating shaft 410 rotatably connected to the first bracket 100. One end of the first rotating shaft 410 is provided with a first flange 411. The second bracket 200 includes a second flange 220. The first flange 411 and the second flange 220 are flange-connected for easy assembly.

[0064] For example, the second flange 220 is located at the first end of the straight rod portion 210.

[0065] For example, the first rotating shaft 410 can be rotatably connected to the first bracket 100 via a bearing or a sliding sleeve. The first bracket 100 further includes a fixing seat 130, which is located at the end of the second rod portion 120 away from the first rod portion 110. A bearing or a sliding sleeve can be installed inside the fixing seat 130.

[0066] In this embodiment, reference continues to be made to... Figure 1 and Figure 2 As shown, the clamping fixture also includes a first stop assembly 420, which is mounted on the first bracket 100 or the second bracket 200. The first stop assembly 420 is used to stop the rotation between the second bracket 200 and the first bracket 100. Taking the copper busbar as an example, when the copper busbar is transferred into the cabinet of the switchgear and is suitable for fastening, the first stop assembly 420 can be controlled to stop the second bracket 200 relative to the first bracket 100. Even if the second bracket 200 remains fixed relative to the first bracket 100, the risk of the copper busbar moving during fastening is reduced, which helps to shorten the installation time of the copper busbar.

[0067] In one feasible embodiment, the first stop assembly 420 includes a first support base 421, a first stop drive member 422, a connecting rod 423, and a sliding rod 424. The first support base 421 is disposed on the first bracket 100, for example, the first support base 421 is disposed on the second rod portion 120, and the first support base 421 is provided with a sliding hole 4211; the first stop drive member 422 is disposed on the first support base 421; the first end of the connecting rod 423 is hinged to the first stop drive member 422; the sliding rod 424 slides through the sliding hole 4211, and the first end of the sliding rod 424 is hinged to the second end of the connecting rod 423. The first stop drive member 422 can drive the sliding rod 424 to slide and press against the first flange 411 via the connecting rod 423, for example, the second end of the sliding rod 424 presses against the periphery of the first flange 411, thereby achieving the stop of the second bracket 200 relative to the first bracket 100.

[0068] For example, the first support base 421 is provided with a relief groove 4212 that communicates with the sliding hole 4211, and the connecting rod 423 is provided in the relief groove 4212, which helps to improve the structural compactness of the first stop assembly 420.

[0069] For example, the first stop drive 422 includes, but is not limited to, a cylinder.

[0070] In this embodiment, reference is made to Figure 1 As shown, the clamping fixture also includes a handle 520, which is provided on the second bracket 200, for example on the straight rod portion 210, to facilitate the rotation of the second bracket 200.

[0071] In this embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 As shown, the clamping bracket 310 includes a first support beam 311, a second support beam 312, and a third support beam 313. The second support beam 312 is located at the first end of the first support beam 311, and a fixed clamping plate 320 is mounted on the second support beam 312. The third support beam 313 is located at the second end of the first support beam 311, and the second support beam 312 and the third support beam 313 are parallel to each other. A clamping drive member 330 is mounted on the third support beam 313. In this embodiment, the clamping bracket 310 supports the fixed clamping plate 320 via the second support beam 312, and supports the clamping drive member 330 and the movable clamping plate 340 via the third support beam 313. The second support beam 312 and the third support beam 313 are connected via the first support beam 311, resulting in a compact structure that facilitates the movement of the plate to be transferred within the clamping bracket 310. It is understood that a space can be formed between the first support beam 311, the second support beam 312, and the third support beam 313 to allow for the movement of the plate to be transferred.

[0072] For example, the first support beam 311, the second support beam 312, and the third support beam 313 may be arranged in a C-shape. It is understood that the first end of the first support beam 311 is connected to the first end of the second support beam 312, and the second end of the first support beam 311 is connected to the first end of the third support beam 313.

[0073] For example, the second support beam 312 and the third support beam 313 are both arranged perpendicularly to the first support beam 311, which is beneficial for the positioning and assembly of the fixed clamping plate 320 and the movable clamping plate 340, improving the parallelism between the fixed clamping plate 320 and the movable clamping plate 340 and the clamping stability of the plate to be transferred.

[0074] For example, the first support beam 311, the second support beam 312, and the third support beam 313 can be configured as rectangular tubes. In some embodiments, the first and second ends of the first support beam 311, the first end of the second support beam 312, and the first end of the third support beam 313 are all beveled, which provides a larger welding area and allows for the formation of a connecting channel between the rectangular tubes, resulting in a neat appearance and improving the structural strength of the clamping bracket 310.

[0075] For example, the second end of the second support beam 312 is covered with a sealing plate 314.

[0076] In one feasible implementation, the fixed clamping plate 320 and the movable clamping plate 340 are both located between the second support beam 312 and the third support beam 313, which is compact and allows the clamping bracket 310 to provide good support for the fixed clamping plate 320 and the movable clamping plate 340, making it convenient for the fixed clamping plate 320 and the movable clamping plate 340 to clamp the plate to be transferred.

[0077] For example, the side of the second support beam 312 facing the third support beam 313 is in contact with the fixed clamping plate 320, which helps to improve the connection stability between the second support beam 312 and the fixed clamping plate 320, and facilitates positioning and assembly, which helps to improve the clamping stability of the fixed clamping plate 320 and the movable clamping plate 340 on the plate to be transferred.

[0078] For example, a reinforcing rib 315 is provided between the fixed clamping plate 320 and the second support beam 312 to improve the connection stability between the two, which is beneficial to improving the clamping stability of the fixed clamping plate 320 and the movable clamping plate 340 for the plate to be transferred. In some embodiments, at least one reinforcing rib 315 is connected to both adjacent sides of the side of the second support beam 312 that is in contact with the fixed clamping plate 320, for example, two to four.

[0079] In one feasible implementation, both the fixed clamping plate 320 and the movable clamping plate 340 are provided with a first anti-slip pad 350. Both the fixed clamping plate 320 and the movable clamping plate 340 can clamp the plate to be transferred through the first anti-slip pad 350, which helps to improve the clamping stability of the fixed clamping plate 320 and the movable clamping plate 340 on the plate to be transferred.

[0080] For example, the first anti-slip pad 350 may be made of resin material.

[0081] For example, the fixed clamping plate 320 is provided with a first folded edge 321, and the movable clamping plate 340 is provided with a second folded edge 341. One of the two first anti-slip pads 350 is located inside the first folded edge 321, and the other is located inside the second folded edge 341. This facilitates the positioning and assembly of the first anti-slip pads 350 and improves the structural strength of the fixed clamping plate 320 and the movable clamping plate 340.

[0082] For example, both the fixed clamping plate 320 and the movable clamping plate 340 are rectangular plates. The fixed clamping plate 320 has first flanges 321 on both sides along the length of the second support beam 312, and the movable clamping plate 340 has second flanges 341 on both sides along the length of the third support beam 313. When the distance between the two first flanges 321 and the distance between the two second flanges 341 are both greater than the width of the plate to be transferred, it helps to reduce the risk of the plate to be transferred coming into contact with the first flanges 321 and the second flanges 341 when it is clamped by the two first anti-slip pads 350.

[0083] In one feasible embodiment, the clamping drive 330 is a telescopic drive, such as a cylinder or electric cylinder. The fixed end of the clamping drive 330 abuts against the side of the third support beam 313 facing the second support beam 312, and the telescopic end of the clamping drive 330 is connected to the movable clamping plate 340, which facilitates the positioning and assembly of the clamping drive 330 and results in a compact structure. Furthermore, the alignment of the side of the second support beam 312 facing the third support beam 313 with the fixed clamping plate 320 helps reduce the torque exerted on the clamping bracket 310 when the fixed clamping plate 320 and the movable clamping plate 340 clamp the plate to be transferred, thereby improving the clamping stability of the fixed clamping plate 320 and the movable clamping plate 340 on the plate to be transferred. Of course, the clamping drive 330 can also be other drive components; this embodiment does not limit its use.

[0084] For example, the telescopic direction of the telescopic end of the clamping drive member 330 is the same as the length direction of the first support beam 311.

[0085] For example, the clamping bracket 310 further includes a reinforcing plate 316. The first support beam 311 and the third support beam 313 are both fixedly connected to the reinforcing plate 316. The fixed end of the clamping drive member 330 is fastened to the reinforcing plate 316 via a first screw (not shown), facilitating the fixed connection between the clamping drive member 330 and the clamping bracket 310. The reinforcing plate 316 also helps to strengthen the structural strength of the clamping bracket 310. In some embodiments, the reinforcing plate 316 can be a bent plate, including a first plate portion (not shown) and a second plate portion (not shown) arranged at an angle. The first plate portion covers the second end opening of the third support beam 313, and both the first support beam 311 and the third support beam 313 are in contact with the second plate portion. The first support beam 311 and the third support beam 313 can both be fixedly connected to the reinforcing plate 316 by welding.

[0086] In one feasible embodiment, the clamping bracket 310 further includes a connecting seat 317, which is disposed on the third support beam 313 and is rotatably connected to the second bracket 200. The structure is simple and facilitates the assembly of the clamping bracket 310 onto the second bracket 200.

[0087] For example, the connecting seat 317 includes two spaced-apart connecting plates 3171, with a plurality of limiting rods 3172 between the connecting plates 3171. It is understood that the two ends of the limiting rods 3172 abut against the two connecting plates 3171 one-to-one. The limiting rods 3172 can be fastened to the connecting plates 3171 via second screw fasteners 3173. It is understood that the connecting seat 317 is hinged to the second bracket 200 via the two connecting plates 3171 for easy assembly. The second bracket 200 can be inserted between the two connecting plates 3171.

[0088] Exemplarily, the connecting seat 317 further includes a connecting block 3174, with at least two limiting rods 3172 passing through the connecting block 3174, and the connecting block 3174 abutting against both connecting plates 3171; the clamping bracket 310 further includes a reinforcing plate 318, which is fixedly attached to the side of the third support beam 313 facing away from the second support beam 312. Exemplarily, the clamping bracket 310 also includes a third threaded connector (not shown), which passes through the third support beam 313 and the reinforcing plate 318 and is fastened to the connecting block 3174. The reinforcing plate 318 helps reduce the risk of stress concentration in the third support beam 313 and improves the structural stability of the clamping bracket 310. It is understood that the head of the third threaded connector can be pressed against the side wall of the rectangular tubular third support beam 313 that is attached to the reinforcing plate 318.

[0089] In this embodiment, reference is made to Figure 1 , Figure 4 and Figure 5As shown, the clamping fixture also includes a second rotating shaft 430 that is rotatably connected to the second bracket 200. The second rotating shaft 430 is rotatably or fixedly connected to the clamping bracket 310.

[0090] For example, the second rotating shaft 430 passes through the connecting plate 3171.

[0091] Exemplarily, the second rotating shaft 430 can be rotatably connected to the second bracket 200 via a bearing or a sliding sleeve. Exemplarily, the second rotating shaft 430 is provided with two first sliding sleeves 441, which can be T-shaped sleeves. One end of each first sliding sleeve 441 has a positioning platform, and the two first sliding sleeves 441 are symmetrically arranged. The second end of the straight rod portion 210 is provided with a second sliding sleeve 442, and the length direction of the second sliding sleeve 442 is perpendicular to the length direction of the straight rod portion 210. Exemplarily, the second end of the straight rod portion 210 has a through hole, and the second sliding sleeve 442 is inserted into the through hole, with both ends of the second sliding sleeve 442 protruding from the straight rod portion 210. The first sliding sleeve 441 is slidably inserted into the second sliding sleeve 442, and the positioning platform abuts against the corresponding end of the second sliding sleeve 442. Exemplarily, the second sliding sleeve 442 can be welded to the straight rod portion 210.

[0092] For example, the rectangular tubular straight rod portion 210 has two through holes corresponding one-to-one with the second sliding sleeve 442. A reinforcing ring 211 is provided at the outer end of each through hole in the straight rod portion 210. The reinforcing ring 211 is welded to the straight rod portion 210 to improve the structural strength of the second support 200. For example, the weld point between the second sliding sleeve 442 and the straight rod portion 210 and the weld point between the reinforcing ring 211 and the straight rod portion 210 can be the same weld point; in other words, this weld point is located between the outer periphery of the second sliding sleeve 442 and the inner periphery of the reinforcing ring 211 for easy assembly. For example, a weld point can also be provided between the outer ring of the reinforcing ring 211 and the straight rod portion 210.

[0093] For example, both the first sliding sleeve 441 and the second sliding sleeve 442 are located between the two connecting plates 3171.

[0094] For example, to prevent the second rotating shaft 430 from disengaging from the first sliding sleeve 441 and the connecting plate 3171, a limiting groove 431 is provided on the periphery of one end of the second rotating shaft 430. The limiting groove 431 is located on the side of the connecting plate 3171 at the corresponding end that faces away from the first sliding sleeve 441. The clamping fixture also includes a limiting member 451, which is inserted into the limiting groove 431 and is fastened to the connecting plate 3171 at the corresponding end by at least two fourth screws 452. It can be understood that the second rotating shaft 430 can rotate with the connecting plate 3171.

[0095] In this embodiment, reference is made to Figure 1 and Figure 4As shown, the clamping fixture also includes a rotation drive 510, which is located between the clamping bracket 310 and the second bracket 200. The rotation drive 510 is used to drive the clamping bracket 310 to rotate, which facilitates the adjustment of the angle of the plate to be transferred and saves manpower.

[0096] For example, the rotation drive 510 includes, but is not limited to, a cylinder or an electric cylinder. The fixed end of the rotation drive 510 is hinged to the second bracket 200. The telescopic end of the rotation drive 510 is hinged to the clamping bracket 310; for example, the telescopic end of the rotation drive 510 is hinged to two connecting plates 3171.

[0097] In this embodiment, reference is made to Figure 4 As shown, the clamping fixture also includes a second stop assembly 460, which is used to stop the rotation between the second bracket 200 and the clamping bracket 310. The second stop assembly 460, in conjunction with the rotation drive member 510, helps to maintain the clamping bracket 310 at the required angle relative to the second bracket 200, ensuring stability and reliability.

[0098] For example, the second stop assembly 460 includes a second fixing block 461 disposed on the second bracket 200, a limiting screw connector 462 passing through the second fixing block 461, and two limiting screw sleeves 463 sleeved on the limiting screw connector 462. The second fixing block 461 is sandwiched between the limiting screw sleeves 463. It can be understood that the limiting screw connector 462 is fastened to the limiting screw sleeves 463. The position of the limiting screw connector 462 is adjusted so that the head of the limiting screw connector 462 abuts against the straight edge of the connecting plate 3171, thereby achieving the stop of the clamping bracket 310 relative to the second bracket 200.

[0099] For example, taking the connecting plate 3171 as having two adjacent and mutually perpendicular straight edges, the angle of the first connecting plate 3171 relative to the second bracket 200 when the head of the limiting screw 462 abuts against one of the two straight edges is set as α, and the angle of the first connecting plate 3171 relative to the second bracket 200 when the head of the limiting screw 462 abuts against the other of the two straight edges is set as β, α-β=90°, which is beneficial for rotating the horizontally placed plate to be transferred to a vertically placed position.

[0100] For example, two second stop components 460 are provided and are configured one-to-one with the connecting plate 3171.

[0101] For example, the second stop assembly 460 includes at least one limiting screw 462, such as two.

[0102] In this embodiment, reference is made to Figure 1As shown, the clamping fixture also includes a control component 600. The clamping drive 330, the first stop drive 422, and the rotation drive 510 are all electrically connected to the control component 600. The control component 600 is used to control the operation of the clamping drive 330, the first stop drive 422, and the rotation drive 510. In this embodiment, the control component 600 includes at least three control elements, including but not limited to levers or buttons. For example, the control element corresponding to the clamping drive 330 can be a lever, the control element corresponding to the first stop drive 422 can be a button, and the control element corresponding to the rotation drive 510 can be a lever.

[0103] For example, the control component 600 may be located on the first bracket 100, or for example, on the second rod portion 120, for convenient operation.

[0104] Reference Figures 6 to 8 As shown, this embodiment also provides a clamping device, which includes a power-assisted robot 700 and the aforementioned clamping fixture. The end of the power-assisted robot 700 is detachably connected to the clamping fixture, and the power-assisted robot 700 is used to transfer the clamping fixture. In this embodiment, the power-assisted robot 700, in conjunction with the clamping fixture, facilitates the transfer and angle adjustment of the workpiece to be transferred, reduces manpower and effort, and shortens the time required.

[0105] In this embodiment, reference is made to Figure 6As shown, the power-assisted manipulator 700 includes a base 710, a first support rod 720, a second support rod 730, a third bracket 740, a lifting drive component 750, a fourth bracket 760, and a rotating joint 770. The first ends of the first support rod 720 and the second ends of the second support rod 730 are rotatably connected to the base 710, and the second ends of the first support rod 720 and the second support rod 730 are rotatably connected to the third bracket 740. The first support rod 720 and the second support rod 730 are parallel to each other. The lifting drive component 750 is located between the base 710 and the second support rod 730. It can be understood that the base 710, the first support rod 720, the second support rod 730, and the third bracket 740 form a parallelogram linkage mechanism 423. In this embodiment, the rotation direction of the first support rod 720 and the second support rod 730 relative to the base 710 and the third bracket 740 can be set to the horizontal direction, and the line connecting the rotation center of the first end of the first support rod 720 and the rotation center of the first end of the second support rod 730 extends vertically. In this embodiment, the lifting drive 750 drives the second support rod 730 to rotate, which can drive the third bracket 740 to rise and fall. Further, the third bracket 740 is rotatably connected to the fourth bracket 760, and a rotating joint 770 is rotatably provided on the fourth bracket 760. The rotating joint 770 is detachably connected to the first bracket 100. It can be understood that the first bracket 100 can rotate relative to the fourth bracket 760 through the rotating joint 770. The rotation direction of the fourth bracket 760 relative to the third bracket 740 can be set to the vertical direction, and the rotation direction of the rotating joint 770 relative to the fourth bracket 760 can be set to the vertical direction. It is understandable that the third bracket 740, the fourth bracket 760, the first bracket 100 and the second bracket 200 are rotatably connected in sequence, which allows the clamping assembly 300 to adjust its position in the horizontal plane. This is beneficial for the clamping device to transfer the plate to be transferred at the required angle and orientation. In addition, in conjunction with the lifting drive component 750, the height of the clamping assembly 300 can be adjusted, which is even more beneficial for the transfer of the plate to be transferred.

[0106] For example, the lifting drive 750 includes, but is not limited to, a cylinder or an electric cylinder.

[0107] For example, a counterweight 731 may be provided on the second support rod 730 to reduce the driving force required for the lifting drive 750 to drive the second support rod 730 to rotate.

[0108] For example, the first bracket 100 and the rotary joint 770 are flange-connected, for instance, the end of the first rod portion 110 away from the second rod portion 120 is flange-connected to the rotary joint 770.

[0109] In this embodiment, reference is made to Figure 7 and Figure 8As shown, the clamping device also includes a third stop assembly 820 and a second stop assembly 460 for stopping the rotation between the third bracket 740 and the fourth bracket 760.

[0110] In one possible implementation, the third bracket 740 and the fourth bracket 760 are rotatably connected via a third rotating shaft 810. Exemplarily, the third bracket 740 is rotatably connected to the fourth bracket 760 via a bearing or a sliding sleeve, and the fourth bracket 760 is fixedly connected to the third rotating shaft 810.

[0111] In one feasible implementation, a stop disc 811 is provided on the third rotating shaft 810, and the third stop assembly 820 includes a second support base 821, a second stop drive member 822, and a stop clamping member 823. The second support base 821 is hinged to the third bracket 740, and a stop clamping part 8211 is provided on the second support base 821. The second stop drive member 822 is fixed on the second support base 821 and connected to the stop clamping member 823. The second stop drive member 822 is used to drive the stop clamping member 823 and the stop clamping part 8211 to clamp the stop disc 811, so as to achieve the stop of the fourth bracket 760 relative to the third bracket 740.

[0112] For example, the second stop drive member 822 includes, but is not limited to, a cylinder. For example, the stop clamping member 823 may be hinged to the telescopic end of the second stop drive member 822.

[0113] For example, both the stop clamping member 823 and the stop clamping part 8211 are provided with a second anti-slip pad 824. Both the stop clamping member 823 and the stop clamping part 8211 can clamp the stop plate 811 through the second anti-slip pad 824, which is beneficial to improve the stopping effect of the third stop assembly 820 on the third bracket 740.

[0114] In this embodiment, reference is made to Figure 7 As shown, the clamping device also includes a fourth stop assembly 830, which is used to stop the rotation between the fourth bracket 760 and the rotary joint 770. The fourth stop assembly 830 and the third stop assembly 820 have the same structure, and will not be described in detail in this embodiment.

[0115] Understandably, when the angles of the fourth bracket 760, the first bracket 100, and the second bracket 200 are adjusted so that the plate to be transferred held by the clamping assembly 300 reaches the desired position, such as the clamping assembly 300 clamping the copper busbar and transferring it into the cabinet of the switchgear and placing it in a position suitable for fastening, the first stop assembly 420 can be controlled to stop the second bracket 200 relative to the first bracket 100, the second stop assembly 460 can be controlled to stop the fourth bracket 760 relative to the third bracket 740, and the third stop assembly 820 can be controlled to stop the rotary joint 770 relative to the fourth bracket 760.

[0116] It is understandable that for connection methods not explicitly mentioned in the text, common connection methods such as threaded connection or welding can be used as needed.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
