[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Please refer to Figures 1-3 A hook for metal pickling, comprising a top rod 101, a hook frame 111 connected to the top of the top rod 101, a lifting device connected to the hook frame 111, thereby driving the top rod 101 to move, thereby realizing the horizontal movement of the parts and the immersion of the parts, two vertical rods 102 connected to the bottom of the two ends of the top rod 101, a fixed rod 103 connected between the two vertical rods 102, support frames 104 arrayed on the fixed rod 103, the support frames 104 being arranged at equal intervals on the two sides of the fixed rod 103, an inner rod 105 slidingly connected inside the fixed rod 103, in another embodiment, holes are arranged on the fixed rod 103 and the inner rod 105, for reducing the overall weight of the hook, strip-shaped grooves 106 being arranged at equal intervals on the two sides of the fixed rod 103, the strip-shaped grooves 106 and the fixed ends of the support frames 104 being located at the same height, the support frames 104 passing through the strip-shaped grooves 106 being connected to the two sides of the inner rod 105, when the inner rod 105 moves in the fixed rod 103, the position of the support frames 104 in the strip-shaped grooves 106 is adjusted, thereby adjusting the distance between the two support frames 104, and then clamping the parts from the inside, the clamping state being referred to Figure 1 and Figure 3 The adjacent two support frames 104 support the pickling parts.

[0028] The following provides a structure for adjusting the position of the inner rod 105 in the fixed rod 103: one of the vertical rods 102 is rotatably connected with a threaded rod 107, the threaded rod 107 is rotatable on the vertical rod 102, and a handle is arranged on the side away from the thread to facilitate manual gripping. By manually rotating the threaded rod 107, the threaded end of the threaded rod 107 is threadedly connected with the inner rod 105, and the position of the inner rod 105 in the fixed rod 103 is adjusted by rotating the threaded rod 107.

[0029] The end of the support frame 104 is connected with a anti-disengagement block 108, which is located at the top of the support frame 104, and is used to prevent the parts from disengaging from the support frame 104 during pickling.

[0030] Specifically, referring to Figure 3 , the support frame 104 is provided with a curved portion 109 for accommodating hollow tubular parts, the curved portion 109 is arranged downward, the support frame 104 is first arranged vertically downward, then arranged downwardly inclined, and finally arranged upwardly inclined, so that the placed parts are in an inclined state, at this time the liquid on the parts will flow to a lower position, thereby improving the speed of fluid discharge from the parts and improving the drying efficiency of the parts.

[0031] Specifically, referring to Figure 2 , the top of the adjacent two anti-disengagement blocks 108 is arranged in opposite directions, which can prevent the parts from disengaging from the two support frames 104, and has the effect of improving stability and safety.

[0032] When it is necessary to clean longer parts, the support frame 104 is too short to effectively support them. The following provides a structure for supporting longer parts: specifically, referring to Figure 1 , the parts are placed on multiple support frames 104, and since the support frame 104 has a curved portion 109, the parts will be located at the lowest position of the curved portion, thereby supporting the parts, and the two ends of the fixed rod 103 are connected with a baffle 110, which can protect the parts from disengaging from both sides.
