Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is further illustrated。

As shown in Figures 1 to 3, the universal Phillips screwdriver of one of the present invention, including cylinder 1, cutter head 2, four knife bars 3, fixed disks 5 with take over a business 9, described four knife bar 3 one end are all hinged with cutter head 2 sidewall, angle between the adjacent knife bar 3 of each two is 90 degree, four knife bars 3 and cutter head 2 constitute the body of tool bit of Phillips screwdriver, for matching with Philip's head screw groove；Described knife bar 3 other end is all hinged with connecting rod 4, and described connecting rod 4 one end and fixed disk 5 are hinged。

The inner chamber of described cylinder 1 is fixedly installed location dish 6, and the upper surface of described fixed disk 5 is fixedly installed two pull bars 8, and described pull bar 8 one end is fixedly installed on the lower surface of 9 after the pilot hole 6-1 of location dish 6；The upper surface of described cutter head 2 is further fixedly arranged on location bar 7, and bar 7 one end, location is fixedly installed on the lower surface of location dish 6。

Described cylinder 1 lateral wall is additionally provided with the outer jacket casing 11 of at least three, the bottom of described outer jacket casing 11 is provided with the outer knife bar 11-1 matched with knife bar 3, the outer wall of described cylinder 1 is threadeded mutually with the inwall of the outer knife bar 11-1 of n-th, the outer wall of the outer knife bar 11-1 of n-th and the inwall of N+1 outer knife bar 11-1 are mutually threaded, the inwall of the outer wall of N+1 outer knife bar 11-1 and N+2 outer knife bar 11-1 is mutually threaded, it should be noted that N is more than or equal to 1。

Further, the upper surface taking over a business 9 described in is fixedly installed draw ring 10。

Further, the inner chamber of described cylinder 1 is fixedly installed restraining position ring block 12, and spacing ring 12 is positioned at the surface of location dish 6；When taking over a business 9 decline, take over a business 9 with the upper surface of spacing ring 12 time, taking over a business 9 cannot decline, and meanwhile, takes over a business the upper surface of 9 with the outer face of cylinder 1 upper end with being in same level。

Further, described fixed disk 5 is circumferentially evenly arranged with four bar groove 5-2 matched with connecting rod 4, and the sidewall of bar groove 5-2 and connecting rod 4 one end are hinged, when angle between the knife bar 3 being arranged oppositely is maximum, connecting rod 4 is all hidden oneself in bar groove 5-2, and namely 4 one-tenth of connecting rod is horizontally disposed with。

When using the present invention, owing to cutter head is fixedly connected with location dish by positioning bar, cutter head cannot move along with pull bar；Therefore, by pulling pull bar to drive fixed disk to move up and down, due to hinged mutually between knife bar and cutter head, between knife bar and connecting rod, between connecting rod and fixed disk, thus realizing adjusting the angle between the knife bar that each two is oppositely arranged；Rotate outer jacket casing simultaneously, make outer knife bar and knife bar be combined, in order to match from different Philip's head screw grooves, be greatly user-friendly to, become general Philip's head screw the Knife tool, and easily take care of, it is not easy to lose。It addition, this simple in construction, reasonable in design, low cost of manufacture。

The above is only the better embodiment of the present invention, therefore all equivalences done according to the structure described in present patent application scope, feature and principle change or modify, and are all included within the scope of present patent application。
