Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail below by embodiment.
Embodiment one:
Please refer to Fig. 1-Fig. 3, a kind of fastener embodiment one of the utility model is a screw, specifically comprises bar portion 2 and head 1, bar portion 2 is provided with outside thread, head 1 one side is fixed on bar portion 2 one ends, and another side has the auxiliary section 11 that cooperates with setting tool, and auxiliary section 11 also comprises at least one limited part.Wherein, head 1 comprises hexagon head, round end, square spigot, countersunk head etc., the auxiliary section is the position that directly contacts with setting tool on the fastening piece with the power effect, the auxiliary section can be the groove that is positioned at head 1 centre, as six prismatic grooves, cross recess, straight groove etc., can also be the face that utilizes head 1 outer ledge setting tool, first-class as hexagonal.
Further, the auxiliary section that embodiment one selects for use is the groove that is positioned at head 1 centre, and this groove is a hexagon groove 11.
Further, hexagon groove 11 has bottom surface and cell wall, and limited part is positioned on bottom surface and/or the cell wall, that is, limited part can be arranged on the bottom surface of hexagon groove 11, also can be arranged on cell wall, can also be arranged on bottom surface and cell wall simultaneously.And the quantity of limited part is not limited to concrete numeral, can determine the quantity of limited part according to actual needs.Wherein, embodiment's one limited part is preferably projection, and is arranged on hexagon groove 11 bottom surfaces, is the cylindrical bump 12 that is provided with to upper process from the bottom surface further.Wherein, the shape of limited part should only not be confined to the cylindrical bump 12 that embodiment one is provided, and can also replace with other shapes, as bumping square, trapezoidal projection or irregularly shaped projection etc.
Be provided with limited part among the embodiment one, promptly cylindrical bump 12, and conventional instrument is not owing to there is the holding part of ccontaining cylindrical bump 12, so in the six prismatic grooves 11 of can not packing into, and then can't open this fastening piece.
Embodiment two
The fastening piece that the utility model embodiment two provides has increased a nut that is spirally connected with bar portion 2 and has formed a kind of bolt on embodiment one basis, clamp by nut and 1 pair of agent of head, and it is more firm to make that fastening piece connects.
Embodiment three
Please refer to Fig. 4, the utility model embodiment three provides a kind of instrument 3 that is used for installing or dismantle the fastening piece that embodiment one and embodiment two provide, this instrument 3 comprises handle 31 and the assembly department that cooperates with the auxiliary section that is positioned at fastener head 1, assembly department is fixed on handle 31 1 ends, and assembly department comprises the corresponding holding part of limited part at least one and the auxiliary section.Concrete, this handle 31 is used for the hand-held and application of force of operator, and this assembly department is used for accurately locating with the fastening piece auxiliary section, and this holding part then is in order to hold the limited part of above-mentioned fastening piece.
Because the hexagon groove 11 and the cylindrical bump 12 that are provided with on the fastening piece that embodiment one and embodiment two provide, therefore the assembly department on embodiment three the instrument 3 is six prisms 32, holding part is preferably groove, further, the circular trough 321 of holding part for matching with cylindrical bump 12.
Using process is: at first circular trough 321 is alignd with cylindrical bump 12 on the fastening piece, with in the six prismatic 32 hexagon grooves 11 that insert on the fastening pieces, last rotatable handle 31 is given the fastening piece application of force, the dismounting fastening piece then.
