The specific embodiment
Figure 1 shows that a kind of screw tool corresponding to this first suitable novel embodiment.Described screw tool comprises a main component 2, and plural screw 1 is installed in the fastener 3 in order to clamp corresponding screw 1 on the main component 2, keeper 5, and a flexible member 8.
Described main component 2 is roughly cylindrical shape, and is provided with the depressed part 14 of plural lengthwise type accepting groove 13 to accommodate corresponding screw 1 respectively and to be positioned at accepting groove 13 next doors on its outer surface.Described main component 2 also is provided with a perforation 15, and this front surface of boring a hole 15 autonomous agent spares 2 extends to its rear surface.
Described keeper 5 is to be contained in the perforation 15 of main component 2 and to be provided with the accommodate corresponding screw 1 of plural locating slot 6 with part.Relative two walls of each locating slot 6 are provided with a pair of pin-and-hole 16.The outer surface of described keeper 5 is provided with plural perforate 17.Described each perforate 17 communicates with adjacent two pin-and-holes 16.Described keeper 5 is provided with accepting hole 18 in the one end, and this accepting hole 18 communicates with described plural locating slot 6.A level and smooth locating surface 10 is located in the described accepting hole 18, and is provided with perpendicular to the axis direction of keeper 5.
Described plural screw 1 is provided with a work head 19 and the end 20 with respect to work head 19.Described end 20 is positioned in the corresponding locating slot 6 and is provided with a supporting surface 21.Described screw tool also is provided with plural pin 25 corresponding to corresponding screw 1, in the time of in screw 1 is contained in corresponding locating slot 6, the perforate 17 that pin is 25 self-align 5 is inserted through the pore 29 of each screw 1 and navigates in the corresponding a pair of pin-and-hole 16 of each locating slot 6, and screw 1 just can rotate to duty shown in Figure 5 from off working state shown in Figure 3 round pin 25 like this.
Described fastener 3 has two double and be set on the depressed part 14 of fastener 3.Thereby described fastener 3 also is provided with plural draw-in groove 22 makes screw 1 to locate with the corresponding screw 1 of buckle.
Described flexible member 8 is a spring in the present embodiment, and is provided with a level and smooth end face 12 and a plurality of flexure strip 9 that extends forwards, backwards from described level and smooth end face 12.Described level and smooth end face 12 is to be fitted on the described location 10.Other was corresponding in the described locating slot 6 in 9 minutes for described flexure strip.With reference to Fig. 3 and Fig. 4, with one of them screw 1 is example, when described screw 1 is in off working state, flexure strip 9 is " a " with the contact point of the end 20 of corresponding screw 1, this moment, flexure strip 9 gave screw 1 one torques that carry out counterclockwise rotating around relative pin 25, shown in arrow " A ", so screw 1 is by in the locating slot 6 of the accepting groove that is pressed in main component 2 13 of safety and keeper 5.With reference to Fig. 5, when screw 1 is in running order, flexure strip 9 is " b " with the contact point of the end 20 of corresponding screw 1, this moment, flexure strip 9 gave 1 one on screw around relative pin 25 and carry out right handed torque, shown in arrow " B ", like this flexure strip 9 just with screw 1 tightly press to locating surface 10, thereby guaranteed the security reliability of screw 1 work.
