Then, the first round tube 51 on the sleeve 41 is pushed to move towards the inside of the sleeve 31, at this time, since the second sealing blocks 59 are clamped on the inner wall of the ring groove 32, the first round tube 51 is pushed to move left to press and fix the spring telescopic rod 513 to shrink, and the first sealing blocks 55 on the left end of the first round tube are driven to move left and are pushed to slide and spread on the left end face of the inner wall of the sleeve 31, so that the four first sealing blocks 55 on the first round tube 51 are clamped between the four spread second sealing blocks 59 to form a ring body, and the tightness of the inner wall of the sleeve 31 after being connected with the sleeve 41 is increased.
And when the four first sealing blocks 55 are clamped between the four expanded second sealing blocks 59, the first spring telescopic rod 45 driving one end of the L-shaped abutting toothed plate 44 on the sleeve 41 is clamped between the conical arc plate 511 and the baffle 512, the sleeve 41 and the sleeve 31 after being abutted are fixed, and then the sleeve 31 and the sleeve 41 are connected through threads by rotating the nut sleeve 46, namely, the connection of the sleeve 31 and the sleeve 41 is completed.
After the four first sealing blocks 55 are clamped between the four unfolded second sealing blocks 59, a trigger rod 610 on the right end face of the first sealing block 55 is inserted into the arc-shaped hollow block 61 along a socket formed in the surface of the arc-shaped hollow block 61, and abuts against one end of a deflection plate 69 far away from the inclined plane push plate 63, the abutting force of the deflection plate 69 on the L-shaped inserting rod 65 is relieved through the deflection of the deflection plate 69, at the moment, the L-shaped inserting rod 65 extends out of the inside of the arc-shaped hollow block 61 under the action of the pushing force of the fourth spring telescopic rod 64 and is inserted into a socket formed in the end face of the arc-shaped hollow block 66, locking of the contact end face of the arc-shaped hollow block 66 and the arc-shaped hollow block 61 is completed, dislocation between the arc-shaped hollow block 66 and the arc-shaped hollow block 61 is avoided, and stability of connection between the arc-shaped hollow block 66 and the arc-shaped hollow block 61 is ensured.
When two cables are required to be disassembled, the internal thread pipe 47 is rotated to drive the rotary gear 48 to rotate, the L-shaped abutting toothed plate 44 is pulled to move left, the power spring telescopic rod 62 is abutted and pushed to compress when the L-shaped abutting toothed plate 44 moves left, the inclined plane push plate 63 is pushed to move left to squeeze one end of the L-shaped inserting rod 65 when the power spring telescopic rod 62 is compressed, the L-shaped inserting rod 65 is pulled out of the connecting arc block 66 and moves towards the direction close to the power spring telescopic rod 62, and after the inclined plane push plate 63 and the L-shaped inserting rod 65 are separated, the L-shaped inserting rod 65 abuts against one end of the clamping plate 67 far away from the trigger rod 610;
and in the process of moving left the L-shaped abutting toothed plate 44, the abutting is performed on the outer wall of the conical arc plate 511, because the spring shrinkage tube 510 is in the shortest compression length, when the L-shaped abutting toothed plate 44 moves left, the first spring expansion rod 45 on the left end of the L-shaped abutting toothed plate is compressed and moves to the left side of the conical arc plate 511, the nut sleeve 46 is rotated to separate from the threads 33 on the outer wall of the sleeve 31, and then the sleeve 41 is pulled left by a user, so that after the first spring expansion rod 45 on the left end of the sleeve 41 extrudes the conical arc plate 511 to move right and be clamped in the cambered surface groove on the left side of the baffle 512, the first spring expansion rod 45 is guaranteed to move right to the right side of the baffle 512, and the sleeve 41 and the sleeve 31 are separated.
