DETAILED DESCRIPTION

[0013] See also Figure 1-5 The present embodiment is an adjustable high-strength comb frame 2 structure, comprising a bracket 1 and a comb frame 2, wherein the bracket 1 is provided with a slot matching the comb frame 2, the slot is arranged through the bracket 1, a gear 10 is arranged in the bracket 1, a rack 11 is arranged at one end of the comb frame 2 facing the bracket 1, the rack 11 is meshed with the gear 10, a rotating shaft 9 is arranged at the center of the gear 10, the rotating shaft 9 is fixedly connected with the gear 10, both ends of the rotating shaft 9 are rotatably connected with the bracket 1, one end of the rotating shaft 9 extends out of the side wall of the bracket 1 and is provided with a ratchet 5, and the side wall of the bracket 1 is also provided with a pawl 6 matching with the ratchet 5, when the pawl 6 overlaps with the ratchet 5, the comb frame 2 cannot move outward. The comb frame 2 of the present invention is made of aviation aluminum alloy material, which has high strength and rigidity.

[0014] Preferably, the other end of the rotating shaft 9 extends out of the side wall of the bracket 1 and is provided with a locking nut 12, and the locking nut 12 is used to lock the rotating shaft 9 so that the rotating shaft 9 cannot rotate.

[0015] Preferably, a pin hole is provided at the other end of the rotating shaft 9, and the pin hole is used to install a pin so as to manually rotate the rotating shaft 9.

[0016] Preferably, the rotating shaft 9 is located outside the ratchet 5 and is equipped with an end plate 8, and the end plate 8 is connected to the rotating shaft 9 by bolts, so that the end plate 8 can prevent the shaft from being strangled.

[0017] Preferably, the pawl 6 is rotatably connected to the bracket 1 via a fixed shaft 7 , and a torsion spring is provided between the pawl 6 and the fixed shaft 7 , so that the pawl hook portion of the pawl 6 is tightly attached to the ratchet 5 .

[0018] Preferably, the comb frame 2 includes two vertical support plates, and one end of the two support plates facing the bracket 1 is provided with a toothed structure, which is processed into a shape matching the gear 10, and the toothed structures of the two support plates are meshed with the gear 10 at the same time.
