[0039] The processing mechanism 2 includes a grinding unit 21 . The grinding unit 21 is located on the surface of the housing 11 . The grinding unit 21 is used to grind and remove the oxide layer on the circuit connector 14 .

[0040] As a further limitation of the processing mechanism 2 of the present invention, the grinding unit 21 includes two connecting boxes 2101, and the side surfaces of the two connecting boxes 2101 close to each other are fixedly connected to the upper surface and the bottom surface of the shell 11 respectively, and the interiors of the two connecting boxes 2101 are rotatably connected to the reciprocating screw rods 2102, and the outer surfaces of the two reciprocating screw rods 2102 are fixedly installed with connecting pieces 2103, and the interiors of the two connecting boxes 2101 are rotatably connected to the toothed shafts 2104, and the outer surfaces of the two toothed shafts 2104 are fixedly installed with rotating disks 2105, and the rotating disks 2105 and the connecting pieces 2103 constitute a Maltese cross movement mechanism, thereby driving the reciprocating screw rods 2102 to rotate intermittently, and the right end of the toothed shaft 2104 penetrates to the connecting rod. A rotating disk 2106 is fixedly installed on the outside of the connecting box 2101, and the outer surfaces of the two reciprocating screw rods 2102 are threadedly connected to moving blocks 2107, and the interiors of the two moving blocks 2107 are rotatably connected to rotating shafts 2108, and the ends of the two rotating shafts 2108 close to the toothed shaft 2104 are fixedly installed with first conical wheels 2109, and the inner walls of the two moving blocks 2107 are fixedly installed with bearing seats 2110, and the inner walls of the two bearing seats 2110 are rotatably connected to rotating shafts 2111, and the left ends of the two rotating shafts 2111 are fixedly installed with second conical wheels 2112, and the outer surfaces of the two second conical wheels 2112 are respectively meshed with the outer surfaces of the two first conical wheels 2109, and the two rotating shafts 21 The right end of each of the two rotating shafts 2108 is fixedly installed with a connecting gear 2113, and the outer surfaces of the two connecting gears 2113 are respectively meshed with the outer surfaces of the two toothed shafts 2104, and the ends of the two rotating shafts 2108 away from the toothed shafts 2104 are fixedly installed with rotating wheels 2114, and the front faces of the two rotating wheels 2114 are fixedly installed with connecting columns 2115, and the front faces of the two rotating wheels 2114 are provided with moving frames 2116, and the inner walls of the two moving frames 2116 are respectively slidably connected with the outer surfaces of the two connecting columns 2115, and the ends of the two moving frames 2116 close to each other are fixedly installed with grinding blocks 2117, and the backs of the two grinding blocks 2117 are in contact with the inner wall of the circuit connector 14. When a worker performs circuit breaker operation, the circuit breaker 14 is opened and closed.

The installation of the limit seats 2119 serves to limit the moving trajectory of the moving frames 2116, thereby preventing the moving frames 2116 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the moving frames 2116.

[0043] The specific implementation method of this embodiment is as follows: the worker first rotates the rotating disk 2106, so that the rotating disk 2106 drives the toothed shaft 2104 connected thereto to rotate, and then the toothed shaft 2104 drives the connecting gear 2113 meshing with it to rotate, and at the same time the connecting gear 2113 drives the rotating shaft 2111 and the second conical wheel 2112 to rotate, so that the second conical wheel 2112 drives the first conical wheel 2109, the rotating shaft 2108 and the rotating wheel 2114 to rotate, and then the rotating wheel 2114 drives the connecting column 2115 to rotate, and then under the restriction of the limit seat 2119, the connecting column 2115 drives the moving frame 2116 The movable frame 2116 moves up and down by reciprocating, so that the sanding block 2117 moves up and down, and the sanding block 2117 grinds the inner wall of the circuit connector 14 up and down. At the same time, during the rotation of the tooth shaft 2104, the tooth shaft 2104 drives the rotating disk 2105 to rotate, so that the rotating disk 2105 intermittently drives the connecting piece 2103 to rotate, and then the rotating disk 2105 drives the reciprocating screw rod 2102 to rotate, so that the reciprocating screw rod 2102 intermittently drives the movable block 2107 to move left and right, so as to grind different positions of the circuit connector 14, thereby ensuring the stability of the connection between the line and the circuit breaker.

The inner wall of each fixing seat 2220 is slidably connected to the outer surface of the tooth rod 2212. The installation of the fixing seat 2220 limits the moving trajectory of the tooth rod 2212, thereby preventing the tooth rod 2212 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the tooth rod 2212.

The ends away from each other are fixedly installed with a fixing disk 309. The worker rotates the fixing disk 309 to move the clamping block 306 toward the side close to each other, so as to clamp and fix the line. The sides away from each other of the two connection boxes 2101 are fixedly installed with a mounting bracket 310. The internal sliding connection of the two mounting brackets 310 is connected to a limiting rod 311. The two limiting rods 311 are both clamped in the inside of the fixing disk 309. The ends of the two limiting rods 311 away from the fixing disk 309 are fixedly installed with a locking block 312. The backs of the two locking blocks 312 are fixedly installed with two connecting springs 313.

Each slider 319 is slidably connected inside the sliding groove 320. The installation of the slider 319 and the sliding groove 320 serves to limit the moving trajectory of the clamping block 306, thereby preventing the clamping block 306 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the clamping block 306.

[0053] The specific implementation of this embodiment is as follows: after the processing of the processing mechanism 2 is completed, the worker inserts the circuit into the circuit connector 14, and then the worker rotates the fixing bolt 17 so that the fixing bolt 17 drives the fixing plate 18 to move to the side close to the circuit, so that the fixing plate 18 presses the circuit, so that the circuit contacts the circuit connector 14, and then the worker fills the airbag ring 301 with inert gas through the inflation tube 302, so that the outer surface of the airbag ring 301 contacts the outer surface of the circuit, and at the same time, the airbag ring 301 seals the connection box 2101, and then the worker rotates the fixing plate 309 so that the fixing plate 309 drives the rotating rod 307 and the rotating gear 308 to rotate, so that the rotating gear 308 drives the meshing with it. The rack ring 304 connected together rotates, thereby causing the rack ring 304 to drive the moving rod 305 to slide inside the rack ring 304, and at the same time, the moving rod 305 drives the clamping block 306 to move toward the side that is close to each other, so that the clamping block 306 clamps and limits the line to prevent the line from being separated from the circuit connector 14 due to external vibration. Then, the fixing spring 314 is pressed to make the moving column 315 move away from the locking block 312, and then the worker clamps the limiting rod 311 into the inside of the fixed disk 309, and then the worker loosens the fixing spring 314, so that the moving column 315 is clamped into the inside of the locking block 312 under the action of the fixing spring 314, and then the limiting rod 311 locks the fixed disk 309, ensuring a good limiting effect on the line.
