Abstract

The utility model relates to a structure for assembling a cutting nippers holding tube. Head ends of two relatively pivoted connecting parts are respectively pivoted with a blade part and insertion rods on the tail ends are penetrated in a holding tube. The utility model is characterized in that outer ends of the insertion rods are formed into a tapered part and an expanding connecting part; the surface of the expanding connecting part is formed into an elliptical surface which is expanded gradually, and the shape of the cross section from a cone-shaped is a gradually flat elliptical shape. The holding tube is matched with the outline of the expanding connecting part of the insertion rod and the hole tube is deformed and expanded into a flat elliptical tube, and the holding tube and the insertion tube are tight combined and assembled. Thus the assembly is stable, and swinging or falling off is not easy to occur. The holding tube needs not being processed into the flat tube for a second time, which enables the assembly to be fast and convenient.

Description

The assembled configuration that cutting nippers holds a writing brush or pen-write

The utility model relates to cutting nippers, refers in particular to the assembled configuration that a kind of follow-on cutting nippers holds a writing brush or pen-write.

The structure that cutting nippers commonly used holds a writing brush or pen-write is roughly two kinds, as shown in Figure 1-Figure 3 a kind of, head end by two connecting portions 10 that articulate relatively respectively articulates blade part 11, the inserted link 12 of tail end wears and holds a writing brush or pen-write 13, this openend 14 of 13 of holding a writing brush or pen-write is pressed into flat tube 15 earlier, the most grooves 16 of the necessary moulding in the surface of the inserted link 12 of flat, after in the flat tube 15 of inserted link 12 insertion holding rods 13, salient point 17 was sticked in the groove 16 of inserted link 12 in punching press flat tube 15 surfaces formed again, its major defect is: not only make 13 the program complexity of holding a writing brush or pen-write, it is more that assembling expends man-hour, and after its assembling, only utilize the interior salient point 17 of flat tube 15 to snap in groove 16 inside of inserted link 12, in the use during application of force, holding a writing brush or pen-write 13 is easy to generate and rocks, even comes off.Another kind of common features such as Fig. 4-shown in Figure 5, its inserted link 12 ' and hold a writing brush or pen-write and 13 ' be the pipe shape, after its combination of pegging graft, the same defective of rocking or coming off that easily produces in the use.

The assembled configuration that provides a kind of follow-on cutting nippers to hold a writing brush or pen-write is provided the purpose of this utility model.The inserted link that its cutting nippers tail end protrudes out is processed into special shape, overcomes the drawback of prior art, reaches the processing winding easily with in conjunction with firm purpose.

The purpose of this utility model is achieved in that the assembled configuration that a kind of cutting nippers holds a writing brush or pen-write, head end by two connecting portions that articulate relatively respectively articulates blade part, in the inserted link of tail end wears and holds a writing brush or pen-write, the outer end formation tapered portion and the expansion that it is characterized in that this inserted link meet portion, this expansion connects the ellipsoid of the surface formation flaring of portion, is gradually flat ellipse from its cross section shape of tapered portion.

Major advantage of the present utility model is: become the flattened oval Guan Ercheng winding of combining closely because the expansion that cooperates inserted link of holding a writing brush or pen-write connects portion's profile to both sides distortion expander, its winding is firm, do not shake or come off, and it holds a writing brush or pen-write and do not need secondary operations to become flat tube, make winding efficient and convenient.

Further specify below in conjunction with preferred embodiment and accompanying drawing.

Consult Fig. 6-Figure 12, the utility model respectively articulates blade part 11 by the head end of two connecting portions 10 that articulate relatively, the inserted link 42 of tail end wears and holds a writing brush or pen-write in 43, the outer end formation tapered portion 20 and the expansion that it is characterized in that this inserted link 42 meet portion 22, this expansion connects the ellipsoid 23 of the surface formation flaring of portion 22, from tapered portion 20 its cross section shapes is gradually flat ellipse, consults Fig. 9-Figure 11.During assembling, 43 the openend 24 of holding a writing brush or pen-write inserts from the conical pipe 20 of inserted link 42, hold a writing brush or pen-write 43 both sides connect the flat gradually of portion 22 with expansion, also become flat gradually, be tight affixed location and meet portion 22 with expansion, do not need punching press clamping again, have the effect that does not shake and come off in easy to assembly and the use.

Claims

1, the assembled configuration that holds a writing brush or pen-write of a kind of cutting nippers, head end by two connecting portions that articulate relatively respectively articulates blade part, in the inserted link of tail end wears and holds a writing brush or pen-write, the outer end formation tapered portion and the expansion that it is characterized in that this inserted link meet portion, this expansion connects the ellipsoid of the surface formation flaring of portion, is gradually flat ellipse from its cross section shape of tapered portion.
