s1, when the pipe bodies (1) are connected with each other, the embedded ring (9) is embedded into the mounting groove (2), the embedded ring (9) penetrates through the air bag (3), the embedded ring (9) extrudes the pressing rod (7), the pressing rod (7) moves to drive the piston (6) to move, the piston (6) moves to extrude the air in the groove bodies (5) into the air bag (3) through the air pipe (8), the air bag (3) bulges to enable the embedded ring (9) to be gapless with the mounting groove (2), so that the connection tightness is good, and when the clamping rod (13) moves to one side of the clamping hole (4), the clamping rod (13) is inserted into the clamping hole (4), so that quick connection between protection pipes is completed, and the sealing effect is good after connection;

s2, filling fire extinguishing agent in the storage block (15), injecting air pressure through the air inlet block (19) to enable the air pressure in the air storage block (17) to be slightly larger than the external air pressure, enabling the sealing plate (23) to seal the matched plate (20) through the second spring (22) to ensure air tightness, melting the film (35) at high temperature when a fire happens, enabling the opening (16) to be opened, enabling the fire extinguishing agent in the air storage block (17) to fall from the opening (16) under the high pressure influence under the condition that the film (35) is not limited, enabling a fire source to be blocked, avoiding the fire from being diffused into the other pipe body (1), and protecting the protection pipe effectively;

s3, the third spring (28) enables the winding wheel (27) to wind the binding belt (24), when a cable is inserted, the binding belt (24) is pulled up, the third spring (28) rotates to store force, after the cable is inserted, the binding belt (24) is loosened, the third spring (28) enables the binding belt (24) to play a certain stabilizing role on the cable, and therefore the cable is kept in a straight state in the protective tube, and the cable placement effect is improved;

s4, the iron plate (34) is attached to the ground through the fourth spring (33), the annular iron wire (31) is connected with the iron sheet (30), and the pipe body (1) is grounded through the lead (32), so that generated static electricity is effectively released to the ground through the lead (32), and the influence of static electricity accumulation on the cable is avoided.

7. The method for using an anti-static power cable protection tube according to claim 6, wherein said step S1 further comprises the steps of:

s11, one end of the air pipe (8) is communicated with the inner ring and the outer ring of the air bag (3), and when the air bag is disassembled, the clamping rod (13) is pressed, so that the embedded ring (9) is not limited any more;

the step S2 further includes the steps of:

s21, the film (35) can bear high air pressure, and the film (35) is gradually softened at high temperature, so that the film (35) is easy to fall off.
