The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As Fig. 1-shown in Figure 5, the preferred embodiment of the folder that the utility model provides comprises protecgulum 2, bonnet 1 and handle 3, protecgulum 2 and bonnet 1 are hinged by rotating shaft 5, the two ear seats (unmarked among the figure) of the lower end of bonnet 1 and handle 3 are hinged by rotating shaft 6, as shown in Figure 6 and Figure 7, protecgulum 2 is provided with two deep trouths (unmarked among the figure) that pass for described two ear seats.The top of the protecgulum 2 that handle 3 surrounds is provided with a screw 21.Interior hexagonal screw 11 is located at screw 21, and the upper end of interior hexagonal screw 11 has a groove, and the operation of offering groove on protecgulum 2 has in addition been omitted in this design.Fix shaft 8 is along the length direction setting of handle 3, the groove correspondence on fix shaft 8 and the interior hexagonal screw 11 so that fix shaft 8 can be extracted insertion out when moving up and down from this groove, thus corresponding realization protecgulum 2 and bonnet 1 open locking.
As shown in Figure 6 and Figure 7, locating dowel pin 9, bearing 4, spring 10, lock shaft 7 are located in the handle 3 from the top down successively, and wherein, spring 10 is a compression spring.As shown in Figure 8, overlook sight, bearing 4 ovalizes, and be fixed in (as shown in Figure 1) in the handle 3 by the two-screw 12 that is located at handle 3 both sides.As shown in figure 10, the middle part of fix shaft 8 is to the certain position of outer lug circle 81.Again as shown in Figure 1, fix shaft 8 vertically passes the hole 41 in the bearing 4, the hole 71 (as shown in Figure 9) in the lock shaft 7, and nest 81 is between bearing 4 and lock shaft 7, and spring 10 is set on the fix shaft 8 between nest 81 and the lock shaft 7.
