The fastening column 2 is provided with a limiting groove 22 corresponding to the limiting block 32. The end cap 23 plays a role of abutting against the copper nose or the wire. The pull ring 24 facilitates the removal or insertion of the fastening column 2 into the first fixing hole 31. The limiting groove 22 is used in conjunction with the limiting block 32.

[0041] It is worth mentioning that the first spring 8 is arranged in the second counterbore 55 .

[0042] The use principle of the utility model is now described as follows:

[0043] Insert the fastening column 2 into the fixed end of the copper nose, overlap the limiting groove 22 with the limiting block 32, apply downward pressure to the fastening column 2, the fastening column 2 abuts against the trigger column 62, and pushes the trigger column 62 to move downward, so that the third spring 63 stores energy until the through hole 21 and the third through hole 53 are on the same center line, and the second spring 73 releases the elastic force to push the fixing column 7 out of the third through hole 53, and inserts it into the through hole 21, and provides support for the fixing column 7 through the third through hole 53, thereby ensuring that the fastening column 2 is stably connected to the fixing ring 5, and the first spring 8 applies a downward force, so that the end cap 23 is firmly attached to the copper bus 3, so that the wire or the copper nose is firmly and stably connected to the copper bus 3, thereby completing the fixing of the copper nose by the fastening column 2;

[0044] Hold the insulating plate 75 and apply an outward pulling force to make the fixing column 7 leave the through hole 21 and retract into the third through hole 53. As the fastening column 2 loses resistance, the third spring 63 releases the reaction force to push the trigger column 62 upward, and drives the fastening column 2 to rise a certain distance, and prevents the fixing column 7 from extending after losing the pulling force, thereby completing the removal steps of the copper nose;

[0045] Example 2

[0046] When the thickness of the copper nose is thin, after the through hole 21 at the bottom is fixed by the fixing column 7, the copper nose is still some distance away from the copper bus 3. At this time, it is necessary to hold the insulating plate 75 and apply an outward pulling force to make the fixing column 7 leave the through hole 21, and continue to apply downward pressure to the fastening column 2 to make the copper nose close to the copper bus 3, and then release the pulling force applied to the insulating plate 75, so as to fix the copper nose and adapt to the thickness of different copper noses. Similarly, the wire can be wrapped around the fastening column 2, and the wire and the copper nose are fixed in the same way, which will not be repeated here.

[0047] The above design scheme can make the product have the advantages of convenient operation, stable connection and improved work efficiency.
