[0002] Ship is a general term for various vessels. Ships are vehicles that can sail or anchor in waters for transportation or operations. They have different technical performance, equipment and structural types according to different usage requirements.

[0003] Ships are man-made vehicles that mainly operate in geographical waters. In addition, civilian ships are generally called ships, military ships are called warships, and small ships are called boats or boats. They are generally called ships or boats. The interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that uses external or self-contained energy. The appearance is generally a streamlined envelope that is conducive to overcoming fluid resistance. The materials are constantly updated with the advancement of science and technology. In the early days, they were natural materials such as wood, bamboo, and hemp. In modern times, they are mostly steel, aluminum, fiberglass, acrylic and various composite materials.

[0004] In the process of shipbuilding industry production, in order to improve the utilization of ship space, the wiring of many equipment boxes will be arranged very compactly, especially the conventional thin wires are placed in the corners, and the plug row in the corner cannot use conventional screwdrivers. Therefore, the connected wires will easily loosen and need to be removed and reinstalled. However, since the wiring is in the corner, it is not easy for ordinary straight screwdrivers to extend the blade into the contact point. For this reason, an adjustable screwdriver device is needed to facilitate the adjustment of the bending angle of the blade, so as to facilitate the insertion into the wiring and make the wiring firm. Summary of the invention

[0005] The purpose of the present invention is to provide an adjustable screwdriver device to overcome the defect that the bending angle of the blade of a conventional screwdriver is not easy to adjust.

[0006] The technical solution to achieve the above purpose is: an adjustable screwdriver device includes a handle, the bottom end of the handle is connected to a handle, the upper end of the side wall of the handle is connected to a driving mechanism, the side wall of the handle is provided with a supporting and limiting mechanism, and the bottom end of the handle is installed with a rotating mechanism.

[0007] Preferably, the driving mechanism includes a connecting ring, a screw, a clamping ring, a connecting block, a rack and a sliding hole, the upper end of the side wall of the tool handle is connected to a connecting ring, the side wall of the connecting ring is threadedly connected to a screw, the bottom end of the side wall of the screw is connected to two clamping rings, the side wall of the screw passes through the side wall of the connecting block, the connecting block is located between the two clamping rings, the side wall of the connecting block is connected to a rack, and the side wall of the rack is provided with a plurality of sliding holes distributed in an array.
