No additional power supply is required, and it is not restricted by the region. The flexibility and scope of use are improved. The support column 1 is supported by the support base 3 to improve the stability of the support column 1. At the same time, the support column 1 and the support base 3 are connected by multiple adjustment rods 4, and a triangular stable structure can be formed in all directions, which greatly improves the overall stability of the ladder.

[0061] In the process of tightening the wire rope 804, the fixed pulley group 801 and the movable pulley group 802 are close to each other, and the support column 1 is slidably arranged inside the guide hole 204 of the support column to achieve the purpose of lifting and lowering the lifting slide 2. Of course, the more strands the pulley group has, the more labor-saving it is. As the number of strands increases, it can achieve the purpose of saving labor for the staff, making it convenient for the operators to lift and lower at any time. When a certain height is reached, the winding limit pin 807 on the winding wheel 803 is pulled out and abutted against the winding handle 806 on the winding wheel 803, and the lifting slide 2 can be prevented from lifting and lowering, which is convenient for the workers to work and improves the convenience of use.

[0062] The upper end of the upper adjusting rod 401 is fixedly connected to the upper threaded head 605 by a thread, and the upper adjusting rod 401 and the lower adjusting rod 402 are screwed together by threads, so the overall length of the adjusting rod 4 can be adjusted, and the lower adjusting rod 402 is threadedly connected to the lower threaded head 707, which is convenient for disassembly and assembly of the adjusting rod 4, and the workbench mounting groove 901 is inserted into the lifting slide 2 and clamped in the groove on the upper side of the insulating platform support arm 206, which is convenient for disassembly and assembly of the insulating workbench 9, and the support column mounting column 306 can be directly inserted into the driving slide groove 101 of the support column 1, which is convenient for removing the support column 1 from the support base 3, so it is convenient to disassemble and assemble the entire device, and convenient for later transportation and carrying.

[0063] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0064] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0065] The above description shows and describes several preferred embodiments of the present invention, but as mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field. Changes and variations made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
