The utility model is characterized in that the long tail rod and the nut are welded into integration in a tadpole shape. When the utility model is used for construction, the long tail rod is clamped on the side face of a workpiece to form a fastening function naturally; each circle of rotation is effective no matter the utility model rotates towards the left or the right. The utility model has the advantages of high work efficiency, time saving, labor saving and convenient operation.

Description

Long-tail bar on-slip nut

The utility model relates to standard piece, refers to a kind of long-tail bar on-slip nut especially.

Existing general tightening nut, as Fig. 1: in the process of fastening connection piece, because fastener nut 2 is gapped between the bolt 1, be easy to generate and skid, be nut 2 with bolt 1 turn, often must be fixing one with spanner, could screw bolt 1 other end, under harsh conditions, not only increase labor intensity, lose time, and influence job schedule.

The purpose of this utility model is at the problems referred to above, provides a kind of and increases work efficiency, the long-tail bar on-slip nut that reduces labor intensity.

The purpose of this utility model is achieved in that a kind of long-tail bar on-slip nut comprises nut and long-tail bar, and it is characterized in that: long-tail bar and nut are integrally welded, are the tadpole shape.

This structure is when swivel bolt, and every circle all is effective fastening ring, improves 1 times of work efficiency, reduces labor intensity, reduces the use of other attached assistant engineer's tool, can improve especially big part fastening with severe environmental conditions under working efficiency, alleviate working strength of workers.

The utility model further specifies by the following drawings and embodiment:

Fig. 1 is prior art fastening piece figure

Fig. 2 is the utility model fastening piece figure

Referring to Fig. 2: a kind of long-tail bar on-slip nut comprises nut 2 and long-tail bar 4, and wherein long-tail bar 4 is integrally welded with nut 2, is the tadpole shape.On the basis of standard nut 2, utilize semi-finished product to add long-tail bar 4 of weldering during making, make long-tail bar 4 in screwing process, can be stuck on the side of workpiece 3, naturally no matter form fastening effect, be left-handed, dextrorotation, whenever rotating a circle all is effective rotation, increases work efficiency 1 times.

The utility model can be according to user's requirement, the screw thread of design different size standard and the long-tail bar 4 of selection different size.Long-tail bar 4 at least one, on the arbitrary position that is stuck in the fastener side, reach rotation effectively, stop nut 2 and take place in company with the situation of bolt 1 idle running.

The outer periphery of above-mentioned long-tail bar on-slip nut can be six sides, four directions, two sides, circle all can, it is simple in structure, it is convenient especially, time saving and energy saving to operate.

Claims (3)

1, a kind of long-tail bar on-slip nut comprises nut and long-tail bar, and it is characterized in that: long-tail bar and nut are integrally welded, are the tadpole shape.

2, long-tail bar on-slip nut as claimed in claim 1 is characterized in that: above-mentioned long-tail bar at least one.

3, long-tail bar on-slip nut as claimed in claim 1 is characterized in that: the outer periphery of above-mentioned long-tail bar on-slip nut can be six sides, four directions, two sides, circle and all can.
