Embodiment Construction

[0028] The invention provides a hexagon socket screw fastener, such as figure 1 and figure 2 As mentioned above, it includes a rotary cap 1 and a hexagonal column 2. The rotary cap 1 is used to extend into the fastening groove of the wrench to drive the rotary cap 1 to rotate. It includes an inner ring gear 3, a sun gear 4, and a planetary gear 5 meshing with both the inner ring gear 3 and the sun gear 4. The inner ring gear 3 is arranged on the rotating cap 1, and the sun gear 4 is rotatably connected to the rotating cap 1. The sun gear 4 is detachably connected with the hexagonal column 2, and the inner ring gear 3 drives the sun gear 4 to rotate through the planetary gear 5 to make the hexagonal column 2 rotate. On the one hand, the rotary cap 1 is detachably connected to the hexagonal column 2, which is convenient for replacing the hexagonal column 2 of different lengths and radial dimensions, not only suitable for occasions where the installation of hexagonal socket hea...

Abstract

The invention discloses a hexagonal socket screw fastener, which solves the problems of low disassembly and assembly efficiency and inconvenient operation of the internal hexagonal screw. The hexagonal groove of the hexagonal screw drives the hexagonal screw to rotate. It also includes the inner ring gear, the sun gear and the planetary gear meshing with the inner ring gear and the sun gear. The inner gear ring is set on the rotating cap, and the sun gear is connected to the On the rotating cap, the sun gear is detachably connected to the hexagonal column, and the inner ring gear drives the sun gear to rotate through the planetary gear to make the hexagonal column rotate. The invention is not only convenient to operate but also has a wide application range.

Description

technical field [0001] The invention relates to an inner hexagon screw fastener. Background technique [0002] The installation and disassembly of hexagonal screws generally use hexagonal wrench. The traditional hexagonal wrench includes a handle and a connector. The handle and connector have the same size and are vertically integrated. When in use, insert the connector into the hexagonal groove of the hexagonal screw. , and then turn the handle to tighten the hexagonal screw. When the space around the hexagonal screw is narrow, the wrench cannot reach in. Even if it can, the hexagonal screw cannot be tightened due to the limited rotation of the handle. In the groove, the obliquely placed connector is easy to damage the groove wall of the hexagonal groove, and eventually the hexagonal screw is necrotic and cannot be disassembled. Carrying all specifications of the Allen key increases the burden on the operator. [0003] In order to solve the above-mentioned problems, the p...
