Unrelated person malfunction equipment, with electrical junction box 2 wherein while being flexibly connected, lid 9 is provided with lock, can on lid 9 one sides
Further to increase the safety coefficient at scene.
Further Anti-rope drop 3 is stone dead wire, cotton or flexible plastic material, can increase the service life of Anti-rope drop.
Further power outlet 8 includes two-phase and three-phase socket, can meet the different power taking demands in scene.
The further inner ring of slack adjuster 5 is provided with anti-skidding rubber ring with the contact surface of cable 10, cable can be avoided to occur
Loosen and cause plug from falling, in use, ensureing Anti-rope drop（3）Length inserted less than the fixed position of slack adjuster 5 to power supply
First 6 length, so ensure that attaching plug 6 consolidates connection with socket 8 all the time.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
For art personnel；On the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
