The technical scheme that adopts for achieving the above object is a kind of terminal device, and this device comprises connecting screw rod, the attaching nut who is connected with connecting screw rod and be arranged on binding ring in the attaching nut;
Described binding ring is an elastic metallic ring jaggy;
Described attaching nut's inwall is provided with internal thread and internal thread clearing end, and the top bore of described internal thread clearing end is greater than its terminal bore, and the top of described elastic metallic ring and described internal thread clearing end mates.
End the corresponding attaching nut of described connecting screw rod is provided with a blind hole.
Described elastic metallic ring one end is provided with chamfering along the outer of elastic metallic ring, the top coupling of described chamfering and described internal thread clearing end.
The described elastic metallic ring other end is provided with chamfering along the outer of elastic metallic ring, is equipped with an inclined-plane in the blind hole port of described connecting screw rod along port inner wall, the chamfering of the described elastic metallic ring other end and described inclined-plane coupling.
The other end of described connecting screw rod also is provided with a connector, also is provided with a connecting hole on connector.
The beneficial effects of the utility model are: the inwall the attaching nut is provided with internal thread and internal thread clearing end, the top bore of its internal thread clearing end is greater than its tail end bore, the elastic metallic ring set put in the attaching nut and with the top coupling, again connecting screw rod is screwed into the metallic power line that the attaching nut tightens in the elastic metallic ring and gets final product.When the terminal device is separated with lead, want earlier connecting screw rod to be back-outed in the attaching nut, block the attaching nut on the other hand, another hand is provided with female direction with lead toward the attaching nut and releases, take out the elastic metallic ring, again lead and attaching nut are separately got final product; This device is reusable, and is very convenient during use, do not need specific purpose tool can reach the purpose of locking, and simple to operate, safe and reliable, simultaneously, the user not only saves time but also laborsaving in use, has improved operating efficiency greatly.

[embodiment]
For the technical solution of the utility model is described in further detail, do detailed explanation below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model provides a kind of terminal device, and this device comprises connecting screw rod 1, the attaching nut 3 who is connected with connecting screw rod 1 and be arranged on binding ring in the attaching nut 3; Described binding ring is one jagged 21 elastic metallic ring 2, and as shown in Figure 3, wherein elastic metallic ring 2 adopts and shrinks the preferred metal making, as copper sheet, iron plate or metal alloy; Described attaching nut's 3 inwall is provided with internal thread 31 and internal thread clearing end 32, and the top bore d2 of described internal thread clearing end 32 is greater than its terminal bore d1, and described elastic metallic ring 2 mates with the top of described internal thread clearing end 32.
As shown in Figure 4, connecting screw rod 1 corresponding attaching nut's 3 a end is provided with a blind hole 13.
As shown in Figure 3, elastic metallic ring 2 one ends are provided with chamfering 22 along the outer of elastic metallic ring 2, the top coupling of described chamfering 22 and described internal thread clearing end 32.
Elastic metallic ring 2 other ends are provided with chamfering 23 along the outer of elastic metallic ring 2, are equipped with an inclined-plane 14 in the port of the blind hole 13 of described connecting screw rod 1 along port inner wall, as shown in Figure 4; The chamfering 23 of described elastic metallic ring 2 other ends and described inclined-plane 14 couplings.
The other end of connecting screw rod 1 is provided with a connector 11, also is provided with a connecting hole 12 on connector 11.
Use the terminal method of terminal device of the present utility model as follows:
This method comprises the following step:
