[0029] In the embodiment, when the height of the metal piece needs to be adjusted according to the height of the metal piece, the motor 5 is started, the motor 5 drives the lead screw 4 to rotate, and the lifting seat 6 moves along the lifting groove 3 due to the threaded connection between the lead screw 4 and the lifting seat 6. The lifting seat 6 drives the suspension arm 7 to move, and the electric hoist 8 moves along with the suspension arm 7, so as to adjust the height of the suspension arm 7 and the electric hoist 8. When the suspension arm 7 moves, the support plate 9 and the reinforcing rod 10 also move. The reinforcing rod 10 supports the suspension arm 7, the support plate 9 drives the limit block 11 to move along the limit groove 13, the limit block 11 drives the gyro wheel 12 to move, and the gyro wheel 12 rotates, so as to reduce the friction between the limit block 11 and the limit groove 13.

Since the electric hoist 8 is a mature product in the prior art, its specific structure and working principle are not described here. When the gyro wheel 12 needs to be disassembled, repaired or replaced, the motor 5 is started, the limit block 11 drives the gyro wheel 12 to move downward, and the limit block 11 is moved to the overhaul opening 14. At this time, the gyro wheel 12 moves to the overhaul opening 14, the gyro wheel 12 is rotated, the gyro wheel 12 drives the rotating ring 21 to rotate, and the rotating ring 21 is separated from the connecting rod 20 due to the threaded connection between the rotating ring 21 and the connecting rod 20. The gyro wheel 12 can be disassembled, and the replaced gyro wheel 12 can be installed by using the reverse operation.

[0030] Please refer to Figures 1-5 As an embodiment for illuminating the working area: a plurality of illuminating lamps 15 are symmetrically fixed on the suspension arm 7, a driving plate 16 is slidably connected on the suspension arm 7 through a track structure, an electric push rod 17 is fixed on the suspension arm 7, the driving end of the electric push rod 17 is fixedly connected with the driving plate 16, a plurality of connecting arms 18 are respectively fixed on both sides of the driving plate 16, and a cleaning sponge 19 is fixed on each connecting arm 18.

[0031] More specifically, the plurality of lighting lamps 15 can be turned on to increase the brightness of the working area. When the exterior of the lighting lamp 15 needs to be cleaned, the electric push rod 17 is started to drive the driving plate 16 to move back and forth along the sliding connection with the suspension arm 7. The driving plate 16 drives the plurality of connecting arms 18 to move back and forth, and the connecting arms 18 drive the cleaning sponge 19 to move back and forth, so that the cleaning sponge 19 wipes the exterior of the lighting lamp 15 back and forth, thereby cleaning the dust and other impurities adhered to the exterior of the lighting lamp 15.

[0032] In summary, when the height of the suspended arm 7 needs to be adjusted according to the height of the lifted metal part, the motor 5 is started to drive the screw rod 4 to rotate. Since the screw rod 4 is threadedly connected with the lifting seat 6, the lifting seat 6 moves along the lifting groove 3, the lifting seat 6 drives the suspension arm 7 to move, and the suspension arm 7 drives the electric hoist 8 to move, thereby adjusting the height of the suspension arm 7 and the electric hoist 8. When the suspension arm 7 moves, the support plate 9 and the reinforcing rod 10 are also moved. The reinforcing rod 10 supports the suspension arm 7, the support plate 9 drives the limiting block 11 to move along the limiting groove 13, the limiting block 11 drives the roller 12 to move, and the roller 12 rotates, thereby reducing the friction between the limiting block 11 and the limiting groove 13. The electric hoist 8 is started to load and unload the metal workpiece. Since the electric hoist 8 is a mature product in the prior art, its specific structure and working principle are not described here. When the roller 12 needs to be disassembled, repaired or replaced, the motor 5 is started to drive the limiting block 11 to move downward, and the limiting block 11 is moved to the maintenance opening 14. At this time, the roller 12 moves to the maintenance opening 14, the roller 12 is rotated, the roller 12 drives the rotating ring 21 to rotate, since the rotating ring 21 is threadedly connected with the connecting rod 20, the rotating ring 21 is separated from the connecting rod 20, and the roller 12 can be disassembled. The replaced roller 12 can be installed by using the opposite operation.

[0033] The plurality of lighting lamps 15 can be turned on to increase the brightness of the working area. When the exterior of the lighting lamp 15 needs to be cleaned, the electric push rod 17 is started to drive the driving plate 16 to move back and forth along the sliding connection with the suspension arm 7. The driving plate 16 drives the plurality of connecting arms 18 to move back and forth, and the connecting arms 18 drive the cleaning sponge 19 to move back and forth, so that the cleaning sponge 19 wipes the exterior of the lighting lamp 15 back and forth, thereby cleaning the dust and other impurities adhered to the exterior of the lighting lamp 15.
