[0044] Refer to Figure 1 And Figure 3The top of the high-altitude operation frame 201 and the protection beam 203 is provided with a sliding hole 204, and the size of the sliding hole 204 is greater than the size of the protection rod 202. Therefore, the protection rod 202 is more smooth during disassembly and assembly. The top of the protection rod 202 is fixedly connected with a handle 2021. The operator can hold the handle 2021 to pull the protection rod 202.
