Detailed description of the invention
Below only with embodiment, the enforcement aspect that the present invention is possible is described, but and be not used to limit the present invention institute for protect category, first give chat bright.
As shown in Figure 1 a, 1 b, a preferred embodiment of the present invention, it comprises six square bars 1, wrenching bar 2, bracing frame 3, pin 4, tail cap 5 and O type silica gel ring 6.
As shown in Figure 2, six square bar 1 two are respectively equipped with 6mm six side 7 and 5mm six side 8.
As shown in Fig. 3 and Fig. 3 a, wrenching bar 2 has a head and an afterbody, and described afterbody has one first groove 11, has several second groove 10 in described first groove.Preferably having ladder hole 9, first groove 11 in described head is cylindrical groove, and the second groove 10 is triangular groove.
As shown in Figure 4, Figure 5, be provided with first through hole 13 passed for spicule in the middle of bracing frame 3, have several several openings 12 installed for pin 4 around described first through hole 13, described sector open 12 is communicated with described first through hole 13.Preferably opening 12 is sector open, three openings 12.
As shown in Figure 6, Figure 7, tail cap 5 has second through hole 15 passed for spicule; Described tail cap 5 second through hole 15 middle part is provided with cannelure 14, damped ring 6 and is located in described cannelure; Preferably described damped ring is O type silica gel ring.
As shown in Figure 1 a, 1 b, during installation, six square bars 1 are fixed on wrenching bar 2 through ladder hole 9.Each pin 4 is installed in each opening 12(respectively movably as sector open) on, and be movably installed in respectively in each second groove (as triangular groove) 10.By pin 4, support member 2 is fixed in the first groove 11 thus, and near the first groove 11 bottom land.Described tail cap 5 is fixed in the first groove 11, and near the first groove 11 notch.
Thus as shown in Figure 8, when specifically using, be by spicule 16(column type or Rhizoma Sparganii type) insert in first, second through hole 13,15 of tail cap 5 and bracing frame 3 centre, can fill, get spicule 16.Because spicule 16 is when penetrating the second through hole 15 and through damped ring 6, therefore adding resistance, playing damping action, producing the first chucking power.When spicule 16 penetrates the first through hole 13, extruding pin 4, again because pin 4 is fixed in the second groove 10 movably, therefore pin 4 is mobile in the second groove 10 inside, produce extruding to the second groove 10 inwall, therefore the second groove 10 inwall produces one second chucking power by pin 4 pairs of spicules 16.By the effect of first, second chucking power, spicule is non-slip in hole, can fill easily, get spicule 16(column type or Rhizoma Sparganii type).Because six square bar 1 two are respectively equipped with 6mm six side and 5mm six side, so can fill, get the soket head cap screw of different size.
