firstly, carrying a back box (1) behind the body through a strap (2), climbing to a steel frame of an electric power tower, starting a first servo motor (16) through a remote switch to drive the first servo motor to rotate anticlockwise with an L-shaped connecting plate (17), so that an attached top plate (29) is positioned at the horizontal position of the lower side of the back box (1), then controlling a second servo motor (18) to drive a first electric telescopic rod (19) to rotate anticlockwise, driving the attached top plate (29) to rotate to a vertical position through a connecting transverse plate (28), and then controlling the first electric telescopic rod (19) to extend to enable the attached top plate (29) to be abutted against the steel frame of the electric power tower, wherein a common magnet (26) connected on the transverse plate (28) is positioned above an inclined iron block (23), and the common magnet (26) has a magnetic force effect on the inclined iron block (23) attached on the top plate (29), the inclined iron block (23) drives the attached top plate (29) to rotate upwards relative to the connecting transverse plate (28), so that the attached top plate (29) always leans against the electric tower body climbed by workers, and the attached top plate (29) is movably connected with the connecting transverse plate (28), and the strip-shaped clamping plate (30) on the attached top plate (29) is also in a movable connection state, so that the climbing of the workers is prevented from being hindered;

when a worker climbs to a corresponding position and stops, the displacement sensing switch (9) senses that the displacement of the worker is unchanged, induction is generated, the extension control circuit of the second electric telescopic rod (25) is electrified, the countdown power switch (8) starts countdown at the moment, the situation that the worker is temporarily stopped is avoided, the position is locked when the worker reaches a set time, the second electric telescopic rod (25) is completely electrified and extends, the fixed tooth block (24) is abutted to the linkage gear (21) at the end of the shaft lever (22) to clamp the linkage gear (21), the shaft lever (22) cannot rotate, the attached top plate (29) cannot rotate relative to the connecting transverse plate (28), meanwhile, when the bar-shaped clamping plate (30) is positioned at the gap of the adjacent steel frames of the electric power tower and has a certain moving space, the bar-shaped clamping plate (30) is kept at a horizontal position under the action of the rebound hinge, and is inserted between adjacent steel frames of the power tower, at the moment, when a worker stays at the corresponding position to reach the set time of the countdown energizing switch (8), the countdown energizing switch (8) enables the electromagnet (36) at the position of each bar-shaped clamping plate (30) to be energized to generate magnetism, the electromagnet (36) generates attraction force on the limiting iron block (37), so that the limiting iron block (37) drives the connecting sliding column (63) to slide rightwards, the convex top blocks (32) on the bar-shaped clamping plates (30) are abutted to the matching convex blocks (38) on the connecting sliding sleeve (34), the bar-shaped clamping plates (30) at each position cannot rotate relative to the connecting sliding sleeve (34) so as to keep the bar-shaped clamping plates at the horizontal position, meanwhile, the countdown energizing switch (8) enables the self-locking motors (41) connected with the connecting sliding sleeves (34) which are paired and separated from each other to be started, and the self-locking motors (41) at the corresponding positions drive the rolling gears (43) to rotate through the set steering direction, the rolling gear (43) rolls along the fixed rack (42), so that the paired connecting sliding sleeves (34) slide together along the attached top plate (29) and approach together, the strip-shaped clamping plates (30) connected to the paired connecting sliding sleeves (34) move together to clamp the steel frame of the power tower at the position, the attached top plate (29) is fixedly butted with the power tower, the attached top plate (29) is fixed relative to the connecting transverse plate (28), the connecting transverse plate (28) is fixed relative to the back box (1) by means of the motor stop self-locking function at each position and is positioned at the lower side of the back box (1), and stable support is carried out to ensure that workers are stably and safely attached to the corresponding position of the power tower;

and thirdly, controlling a third servo motor (51) to rotate forwards through a remote switch, so that the third servo motor (51) drives the tool box (5) to rotate and deviate from a box opening (54) through a cross arm (52), then enabling the tool box (5) to rotate to a horizontal position relative to the cross arm (52) by hand, then controlling a third electric telescopic rod (53) to extend, just inserting the telescopic end of the third electric telescopic rod (53) to the lower side of a connecting convex plate (58), avoiding the tool box (5) in the horizontal position from rotating under the action of an elastic rotating shaft, further facilitating the tool box (5) to serve as an object carrying table, and conveniently classifying and placing different maintenance appliances by an inner tool box (6) rotatably connected with the inner side of the tool box (5).
