Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1 to 6, the screw fixing mechanism for a rotary spanner according to the present invention comprises a housing 1 and a rotary spanner 2, wherein a protruding shaft 11 is provided on both front and rear end surfaces of the housing 1, a rotation hole 21 is provided on the rotary spanner 2, and the rotary spanner 2 is rotatably connected to the protruding shaft 11 of the housing 1 through the rotation hole 21. The upper end surface of the rotary wrench 2 extends leftward to form a flat-shaped force application side 22, a screw 3 is provided on the force application side 22, a nut 4 is provided on the upper end surface of the housing 1, and the screw 3 is screwed to the nut 4.
In order to facilitate the installation of the nut 4, an installation boss 12 is arranged on the upper end surface of the shell 1, a containing part 120 and a cavity 121 are arranged in the installation boss 12, the nut 4 is arranged in the containing part 120, and a tongue 122 abutted against the nut 4 is arranged on the cavity 121.
In order to facilitate the installation of the screw 3, the upper end face and the lower end face of the force application edge 22 of the rotary wrench are respectively provided with a boss 23 and a cone boss 24, wherein the cone boss 24 is matched with the accommodating part 120 on the shell installation boss 12. The boss 23 and the cone boss 24 are coaxially arranged, a first through hole is formed in the boss 23, a second through hole is formed in the cone boss 24, the first through hole is communicated with the second through hole, and the screw 3 is arranged in the first through hole.
In order to prevent the screw 3 from separating from the force application edge 22 of the rotary spanner, a limiting convex rib 232 is arranged on the inner wall of a first through hole of the boss 23.
