It effectively improves the rapid clamping and positioning during the processing of aircraft seat armrests, while also having the advantages of multi-directional adjustment and stable clamping.

[0025] refer to Figure 2The outer diameter of the round hole 606 is smaller than the diameter of the steel ball 607, preventing the steel ball 607 from falling out of the round hole 606. The surface of the fixing sleeve 608 fits into the mounting hole 2. The fixing sleeve 608 has a tapered hole 609 inside, which can be used to lock the steel ball 607 in place. The fixing sleeve 608 is internally threaded with a hexagonal socket head cap screw 610. A second tapered block 611 is fixedly connected to the bottom of the hexagonal socket head cap screw 610. The bottom of the fixing sleeve 608 has an opening groove 612, which allows the hexagonal socket head cap screw 610 to drive the second tapered block 611 to move upward. The second conical block 611 expands the bottom of the fixing sleeve 608 through the engagement of the opening slot 612, so that the fixing sleeve 608 is fixed inside the mounting hole 2. The surface of the insertion tube 601 is fixedly fitted with a fixing nut 613. The interiors of the first fixing plate 3, the second fixing plate 4 and the L-shaped stop block 5 are all threadedly connected to the insertion tube 601. The surface of the insertion tube 601 is provided with external threads. The interiors of the first fixing plate 3, the second fixing plate 4 and the L-shaped stop block 5 are all provided with threaded holes that are compatible with the external threads of the insertion tube 601. The fixing nut 613 can be turned with a wrench, and the insertion tube 601 can be installed with less effort.

[0026] refer to Figure 3 The top of the second fixing plate 4 is fixedly connected to the first screw 7. The surface of the first screw 7 is fitted with an L-shaped push block 8. The inside of the L-shaped push block 8 is provided with a through groove 9 that matches the first screw 7. The top of the first screw 7 is threadedly connected to the first nut 10. Pulling the L-shaped push block 8 allows it to rotate and slide on the surface of the first screw 7 through the cooperation of the through groove 9, so that one end of the L-shaped push block 8 contacts and limits the handrail. Then, the first nut 10 is turned to limit and fix the L-shaped push block 8, and it is also convenient to limit and block the two sides of the handrail.

[0027] refer to Figure 4The top of the first fixed plate 3 has a groove 24. The top of the groove 24 is rotatably connected to a rotating plate 11 via a pin. The top of the rotating plate 11 is fixedly connected to a sliding sleeve 12. An internally threaded tube 13 is fitted inside the sliding sleeve 12. Slider blocks 14 are fixedly connected to both sides of the internally threaded tube 13. The inside of the sliding sleeve 12 has a groove that matches the internally threaded tube 13 and the sliders 14. A rubber top block 15 is fixedly connected to one end of the internally threaded tube 13. A limit ring 16 is fixedly connected to one end of the internally threaded tube 13. A threaded shaft 17 is threadedly connected inside the internally threaded tube 13. The top of the rotating plate 11 is bolted with... Motor 18, the output end of motor 18 is bolted to threaded shaft 17 via coupling. Rotating rotating plate 11 causes rotating plate 11 to rotate at the top of groove 24 via pin. Then, tightening second nut 20, through the cooperation of second screw 19, limits and fixes rotating plate 11, and facilitates the rotation adjustment of rotating plate 11 before limiting and fixing. Then, start motor 18 to drive threaded shaft 17 to rotate forward, causing threaded shaft 17 to drive internal thread tube 13 to slide inside the slide groove. Then, internal thread tube 13 drives rubber top block 15 to contact the handrail, thereby effectively facilitating quick positioning of the handrail.

[0028] refer to Figure 4 Two second screws 19 are fixedly connected to the top of the groove 24. The surface of the second screws 19 is threaded with a second nut 20. The interior of the rotating plate 11 has two arc-shaped grooves 21 that are adapted to the second screws 19. By setting the arc-shaped grooves 21, the rotation of the rotating plate 11 can be maintained without affecting the rotation.

[0029] refer to Figure 1 Two U-shaped grooves 22 are provided on both sides of the base plate 1. The mounting bolts 23 are installed inside the U-shaped grooves 22. By setting the mounting bolts 23, the base plate 1 can be easily installed.

[0030] Brief description of usage: The user inserts the fixing sleeve 608 into the matching mounting hole 2, then uses a hex wrench to tighten the internal hex bolt 610, causing the internal hex bolt 610 to move the second conical block 611 upwards. Simultaneously, the second conical block 611 expands the bottom of the fixing sleeve 608 through the engagement of the opening slot 612, fixing the fixing sleeve 608 inside the mounting hole 2. Pressing the push rod 602 compresses the spring 603, while the first conical block 605... Release the limiting force on steel ball 607, causing it to retract into the insertion tube 601. Then, insert the insertion tube 601 into the fixing sleeve 608. Next, release the push rod 602, and the spring 603 will drive the push rod 602 to return to its original position. This will cause the push rod 602 to drive the first conical block 605 to push out steel ball 607, allowing steel ball 607 to limit the insertion tube 601 through the engagement of the conical hole 609. This facilitates the alignment of the first fixing plate 3, the second fixing plate 4, and the L-shaped stop block 5 with the mounting hole 2. Quickly install and remove the handrail by aligning the back of the handrail with the L-shaped stop 5. Then, pull the L-shaped push block 8 to rotate and slide on the surface of the first screw 7 through the through groove 9, so that one end of the L-shaped push block 8 contacts and limits the handrail. Then, tighten the first nut 10 to limit and fix the L-shaped push block 8, which also facilitates limiting and blocking both sides of the handrail. Next, rotate the rotating plate 11 so that the rotating plate 11 rotates on the top of the groove 24 through the pin. Then, tighten the second nut 20 to limit and fix the rotating plate 11 through the cooperation of the second screw 19, which also facilitates the rotation and adjustment of the rotating plate 11 before limiting and fixing it. Then, start the motor 18 to drive the threaded shaft 17 to rotate forward, so that the threaded shaft 17 drives the internal threaded tube 13 to slide inside the slide groove. Then, the internal threaded tube 13 drives the rubber top block 15 to contact the handrail, which can effectively facilitate the quick positioning of the handrail. Starting the motor 18 to drive the threaded shaft 17 to rotate in reverse can release the limit and facilitate the quick clamping and positioning of the handrail.
