[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:
