Fig. 3 is and the structural representation of the matching used nut of fastening spanner of nut in the utility model;

Wherein, 1-nut body, 2-internal thread, 3-limiting section, 4-clamping limb, 5-No. bis-clamping limbs, 6-deep-slotted chip breaker, 7-No. bis-deep-slotted chip breakers, 8-circular groove, 9-outside screw, 10-outside screw.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:

Shown in composition graphs 1, a kind of fastening spanner of nut, the front end of the front end and No. two clamping limbs 5 that comprise a clamping limb 4 and No. two clamping limbs 5, clamping limb 4 is for being articulated and connected.

A clamping limb 4 is provided with a deep-slotted chip breaker 6, No. two clamping limbs 5 is provided with No. two deep-slotted chip breakers 7, deep-slotted chip breaker 6 and No. two deep-slotted chip breakers 7 are oppositely arranged, in a deep-slotted chip breaker 6 and No. two deep-slotted chip breakers 7, be equipped with internal thread segment.

A deep-slotted chip breaker 6 and No. two deep-slotted chip breakers 7 meet following relation, that is:

When a deep-slotted chip breaker 6 and No. two deep-slotted chip breakers 7 in conjunction with time form a complete circular groove 8, and the internal thread segment in a deep-slotted chip breaker 6 and the internal thread segment in No. two deep-slotted chip breakers 7 are combined to form the internal thread 10 of circular groove, as shown in Figure 2.

In addition, the utility model gives a kind of and the above-mentioned nut matching used nut of fastening spanner.

As shown in Figure 3, a kind of nut, comprises nut body 1, arranges internal thread 2 in nut body 1; Outside screw 9 it is provided with outside nut body 1; It is provided with limiting section 3 in nut body 1 front end.

Preferably, this limiting section 3 is a boss protruding from nut body 1.

Wherein, the internal thread 10 of circular groove mates with outside screw 9 phase of nut body 1 arranged outside.

When carrying out nut and be connected with bolt, a clamping limb 4 and No. two clamping limbs 5 are placed on limiting section 3 place, then a clamping limb 4 and No. two clamping limbs 5 are drawn close to centre, nut body 1 is in the circular groove 8 formed by a deep-slotted chip breaker 6 and No. two deep-slotted chip breakers 7, hold a clamping limb 4 and No. two clamping limbs 5 with a firm grip and turn, to realize the connection of nut and bolt.

Nut screw up with bolt together with after, by a clamping limb 4 and No. two clamping limbs 5 separately, remove the fastening spanner of nut. Nut in the utility model is disposable nut, cannot dismantle after being connected with bolt.

Certainly; more than illustrate and it is only better embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this specification sheets; all equivalent replacement, the obviously variant made, all drops within the essential scope of this specification sheets, ought to be subject to protection of the present utility model.
