[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0024] The following is combined with Figure 1-3 This application is further described in detail.

[0025] Reference Figure 1-2 , a pulley block adopts the following technical solution: it includes: a mounting seat, a first pulley 1 and two second pulleys 2, the first pulley 1 and the two second pulleys 2 are both arranged on one side of the mounting seat 1, the two second pulleys 2 are arranged in parallel, the two second pulleys 2 have the same axial direction, the first pulley 1 is arranged on one side of the middle position of the two second pulleys 2, the axial direction of the first pulley 1 is perpendicular to the axial direction of the second pulley 2, so that the first pulley 1 and the two second pulleys 2 are arranged perpendicularly to the axial direction, so that the cable can be guided in multiple directions, and when the first pulley 1 guides the cable, the two second pulleys 2 can guide and limit the cable, and then guide it through the first pulley 1; conversely, after the cable is guided by the first pulley 1, it can pass through the middle of the two second pulleys 2 and then turn to the side of any one of the second pulleys 2.

[0026] Reference Figure 1-2 The mounting seat includes a carrier plate 3, a mounting plate 5 and two mounting columns 4. The two mounting columns 4 are vertically arranged on the carrier plate 3. The two second pulleys 2 are respectively sleeved on the two mounting columns 4. The mounting plates 5 are respectively fixed to the suspended ends of the two mounting columns 4 by two bolts. In this way, the two second pulleys 2 are respectively installed by the two mounting columns 4, and the mounting plates 5 are fixed to the two mounting columns 4 by bolts, so that it is easy to disassemble and assemble. Of course, the mounting plates 5 can also be fixed by a clamping method.

[0027] Reference Figure 1 The mounting seat also includes two support plates 6, a mounting shaft 7 is arranged between the two support plates 6, the first pulley 1 is sleeved on the mounting shaft 7, and both sides of the two support plates 6 are provided with reinforcing ribs 61 connected to the carrier plate 3. In this way, the first pulley 1 is installed using the mounting shaft 7, and the two support plates 6 support the mounting shaft 7 from both sides, so that the first pulley 1 is more stable, and the setting of the reinforcing ribs 61 further improves the supporting strength of the support plates 6.
