Specifically, the first bottom line hook needle 31 protrudes into the first adjusting hole 322, so as to facilitate adjustment of the length of the first bottom line hook needle 31 extending relative to the first adjusting seat 321, and then an external fastener is used to pass through the first positioning hole 323 and abut against and fix the position of the first bottom line hook needle 31, and the fastener may be a bolt, a stud or a screw.
[0035] The first bottom line hook needle assembly 3 of the present embodiment further includes a first mounting seat 33, a first mounting hole 34 provided on the first mounting seat 33 and used in conjunction with the first adjustment slot 324, and mounting pieces 35 provided at both ends of the first mounting seat 33. External fasteners pass through the first adjustment slot 324 and are connected to the first mounting holes 34. The first mounting seat 33 is connected to the palm frame 2 through the mounting pieces 35. Specifically, the two ends of the first mounting seat 33 are respectively connected and fixed to the palm frame 2 through two mounting pieces 35. The first adjustment seat 321 is moved up and down relative to the first mounting seat 33 to fine-tune the height position. Then, external fasteners are used to pass through the first adjustment slot 324 and are connected to the first mounting holes 34 to achieve connection and fixation between the first adjustment seat 321 and the first mounting seat 33, and the adjustment effect is good.
[0036] The second adjusting member 42 of this embodiment includes a second adjusting seat 421, a second adjusting hole 422 disposed in the second adjusting seat 421, a second positioning hole 423 connected to the second adjusting hole 422, and a first adjusting gap 424 disposed between the second adjusting hole 422 and the second positioning hole 423. The second bottom line hook needle 41 protrudes into the second adjusting hole 422, so that the first adjusting gap 424 can be extended and deformed with the outer diameter of the second bottom line hook needle 41, so that an external fastener passes through the second positioning hole 423 to abut against and position the second bottom line hook needle 41. Specifically, the second bottom line hook needle 41 protrudes into the second adjusting hole 422, and the first adjusting gap 424 can be extended and deformed with the outer diameter of the second bottom line hook needle 41, and has good adaptability, so as to facilitate the replacement and use of second bottom line hook needles 41 of different sizes, and to facilitate the adjustment of the length of the second bottom line hook needle 41 extending relative to the second adjusting seat 421, and then an external fastener is used to pass through the second positioning hole 423 to abut against and fix the position of the second bottom line hook needle 41.
[0037] The second bottom line hook needle assembly 4 of this embodiment also includes a transmission rod 43 and an axis 44 sleeved on the outside of the transmission rod 43. The second adjustment seat 421 is provided with a through hole 425 and a gap groove 426 connected to the through hole 425 at one end close to the axis 44.
