Description

Technical Field

[0001] The utility model relates to the technical field of mechanical product fixing, and particularly relates to a disassembly and assembly tool for anti-falling screws. Background Technique

[0002] For example, in the prior art with the patent publication number CN219953906U and the patent name of an anti-drop screw, by extending both sides of the torsion fastener to form an extension part, the shape of the torsion fastener is increased in bending, so that the width of the torsion fastener in the first direction can be changed without changing the rod diameter of the screw body, and the torque of the anti-drop screw is increased to achieve a better tightening state. The above implementation structure is relatively complex, and the screw belongs to a special type, with a complex structure and high cost.

[0003] Another example is the prior art with the patent publication number CN218397947U and the patent name of a disassembly and assembly tool for anti-falling screws. The device body includes a rotating handle, a tool rod and an anti-falling device. A tool rod is connected to the middle position on one side of the outer wall of the rotating handle. The tool rod is made of iron and passes through the rotating handle through threads. The bottom of the tool rod is connected with an anti-falling device. The anti-falling device includes a magnet, a sleeve, a threaded hole, a cone head and a threaded rod. The bottom of the tool rod is connected with a threaded rod. The sleeve is connected to the threaded rod through threads. A threaded hole is provided at the bottom of the threaded rod. The cone head is connected to the threaded hole through threads. For this disassembly and assembly tool for anti-falling screws, through the setting of the anti-falling device, it is attracted by magnetic force, and the screw is limited by the sleeve, so that the screw will not fall during the disassembly and assembly of the screw, which is convenient for installing the screw and removing and collecting it. The above "disassembly and assembly tool for anti-falling screws" is of the sleeve type and is not suitable for application scenarios with smaller sizes such as self-tapping screws and screws.

[0004] Therefore, when the traditional screw is directly matched with the screwdriver, the screw is prone to swing during installation, and the orientation is inaccurate during tightening, which affects the tightening efficiency. At the same time, the screw is easy to fall off, enter the closed space of the equipment and become a safety hazard and a source of abnormal noise, and also increases the workload of taking it out. For this reason, this application proposes a disassembly and assembly tool for anti-falling screws to solve the above deficiencies. Content of the Utility Model

[0008] A magnetic wire is arranged at the contact position between the bottom of the screwdriver and the self-tapping screw, and the magnetic wire is connected to the first blind hole and can drive the self-tapping screw to rotate.

[0009] In this application, a first blind hole is provided in the self-tapping screw, and a magnetic wire connected to the first blind hole is arranged at the bottom of the screwdriver. Then, the bottom of the screwdriver itself cooperates with the first notch of the self-tapping screw, which can prevent the self-tapping screw from swinging, shaking, and inaccurate positioning. At the same time, the screwdriver directly magnetically adsorbs the self-tapping screw, so as to achieve the functions of preventing falling and accurate orientation; thereby improving the working efficiency of installing and removing screws and avoiding the extra workload caused by the falling of screws; the weight of the self-tapping screw is reduced by about 4% due to the blind hole, which has a certain cost advantage.

[0010] As a further solution of the utility model: the screwdriver includes a tool shank, and a cutter tooth is arranged at the bottom of the tool shank. The cutter tooth is conical and cooperates with the first notch.

[0011] As a further solution of the utility model: a fine hole is provided inside the tool shank, and the magnetic wire is fixed in the fine hole, and the end of the magnetic wire extends out of the fine hole.

[0012] As a further solution of the utility model: the bottom of the self-tapping screw is designed with a conical structure.
