Now lift preferred embodiment and conjunction with figs. is described as follows:

At first, see also Fig. 3 to shown in Figure 5, a kind of Double safety tightening tool of the utility model is characterized in that:

This fastener 10 is one-body molded and is the lamellar body 11 of KanXing Zhuan, and central authorities form an open space, system can supply two

pressing mechanisms

20,30 are provided with, and this

pressing mechanism

20,30 is a main pressing mechanism 20 and a pressing mechanism 30, wherein main pressing mechanism 20 is to comprise a pressing tablet 21 and a torque spring 22, wherein, the side of this pressing tablet 21 is established a storage tank 23 and a through hole 24, stretched through for the axle hinged arm 25 that this torque spring 22 is located in and a head end is established grinding tooth 251 and to fix this pressing tablet 21 between the two side faces of lamellar body 11, and front end is established a stopper section 211 under this pressing tablet 21, can end with bead 111 cards of lamellar body 11 bottom surface settings, this time pressing mechanism 30 is to be connected in main pressing mechanism 20 in addition, and be to comprise a double-action plate 31 and a little torque spring 32, wherein the little axle hinged arm 35 that double-action plate 31 sides also establish that a little storage tank 33 and a little through hole 34 also are located in for this little torque spring 32 and a head end is established grinding tooth 351 stretched through and fixed this double-action plate 31 between the two side faces of lamellar body 11, and front end is established a stopper section 311 under this double-action plate 31, can end with bead 112 cards of lamellar body 11 bottom surface settings; In view of the above, rope two

pressing mechanisms

20,30 that stretched through, firmly restraint of loads, and have the double insurance that can avoid rope to get loose suddenly or rupture.

When assembling, see also Fig. 4 and Fig. 5 and cooperate shown in Figure 3, at first these lamellar body 11 body series are one-body molded, and utilize axle hinged

arm

25,35 two

pressing mechanisms

20,30 to be fixed between the dual side-edge of lamellar body 11 in axle pivot mode, promptly utilize this

hinged arm

25,35 to pass the set through hole 24,34 of this torque spring 22, little torque spring 32 and pressing tablet 21, double-action plate 31, and pressing tablet 21, double-action plate 31 and torque spring 22, little torque spring 32 are fixed in the open space of lamellar body 11, so overall package is finished fastener 10 bodies of the utility model.

When operation is implemented, see also Fig. 6 to Fig. 9 and continue to consult Fig. 4, shown in Figure 5, the stopper section 211 of this pressing tablet 21,311 with the bead 111 of lamellar body 11,112 the two can block backstop mutually, as shown in Figure 6, and when rope 40 desires that the two passes through since then, at first, must earlier the pressing tablet 21 of this main pressing mechanism 20 be pushed, make its pressing tablet 21 be subjected to the big spacing of upspringing of torque spring 25, and this time pressing mechanism 30 double-action plate 31 that can drive this time pressing mechanism 30 when pressing because of the pressing tablet 21 of this main pressing mechanism 20 is subjected to the little torque spring 32 big spacing of also upspringing, as shown in Figure 7, so can for this rope 40 since then spacing stretched through easily, and after stretch through, decontroling pressing tablet 21 pushes, make its home position of rebounding, so can only compress this rope 40, as shown in Figure 8.

And what deserves to be mentioned is, the

pressing mechanism

20,30 of the utility model is a dual security insurance, promptly this rope 40 only is subjected to the outpost of the tax office, two roads, structure design so, not only this rope 40 firmly can be clamped, more can place rope 40 and get loose suddenly, perhaps the danger of fracture suddenly thoroughly provides the guarantee of user's safety.
