[0033] It also includes a vertical force-applying shaft 41, which extends outward from the inside of the sealing seat 33 through the outer extension block 34. A second transverse fixing arm 42 is fixedly provided at the outer end of the force-applying shaft 41, and two pulling arms 39 are respectively rotatably provided on both sides of the second transverse fixing arm 42.

[0034] The sealing seat 33 has an inner cavity 51, the inner side of the force-applying shaft 41 extends into the inner cavity 51, and the inner end of the force-applying shaft 41 is fixedly provided with a moving block 52 that matches the inner cavity 51; a first spring 53 is provided between the bottom of the inner cavity 51 and the moving block 52, and the force-applying shaft 41 can be moved upward by the first spring 53, so that the two clamping blocks 37 remain in an open state.

[0035] The bottom of the inner cavity 51 is fixedly provided with a top block 54, which is fitted by the first spring 53. The top block 54 and the inner wall of the inner cavity 51 form a space for the first spring 53 to compress.

[0036] The movable block 52 has a recessed surface 521 on one side; the sealing seat 33 has a side opening 61, and a side block 62 is fixedly installed in the side opening 61. A locking block 63 is movably installed in the side block 62, and the head of the locking block 63 matches the recessed surface 521.

[0037] A second spring 64 is provided between the fixed outer frame 32 and the locking block 63, and the locking block 63 is pushed towards the inner cavity 51 by the second spring 64;

[0038] A horizontal pull shaft 65 is fixedly installed on the side of the locking block 63 away from the inner cavity 51.

[0046] 5. When it is necessary to remove the inverter body 11, hold the grip block 66 and pull it outward to separate the locking block 63 from the recessed surface 521. The moving block 52 moves upward quickly under the push of the first spring 53, so that the two clamping blocks 37 can quickly release the clamping state of the positioning plug rod 21. Then the inverter body 11 can be removed.
