[0023] 1. When the utility model is in use, a staff member pulls the pull rod to separate the brake pad from the winding roller, and then another staff member pulls the device sub-body to pull the protective net out of the device main body. When it is pulled out to a suitable length, the staff member releases the pull rod, and under the reset action of the spring, the brake pad is tightly attached to the winding roller, thereby playing a braking role. When disassembling and transporting at a later time, the staff member still pulls the pull rod to separate the brake pad from the winding roller, and then rotates the winding roller, so that the protective net can be rolled up inside the device main body, and then the device sub-body can be embedded in the fixing part, thereby reducing the size of the device, making it more convenient to carry and transport, and it can be freely adjusted according to the length used in the application scenario, which is more practical.
