Description

Technical Field

[0001] The present invention relates to the technical field of mechanical tools, and in particular to a screw installation auxiliary tool. Background Art

[0002] In the fields of electrical engineering, mechanical installation, infrastructure construction, etc., screws are essential basic parts. In the field of screw installation, the hand-held screw installation method is generally adopted, that is, the installation method of holding the screw in one hand and the hand drill in the other hand, but this operation is easy to accidentally injure the hand, and it is also easy to cause problems such as screws falling off and tilting, which reduces the work efficiency, affects the construction quality, and even endangers the safety of people or equipment.

[0003] CN109352574A discloses a quick auxiliary tool for automatic screw feeding, which is mainly composed of a suction cup, a screwdriver positioner, a machine base, and a screw clamping block. The characteristics are that the suction cup is installed at the bottom of the machine base to fix the machine base at the position required by the user; the screwdriver positioner is installed in the machine base through a spring and can move up and down; the screw clamping block is located on one side of the machine base, and a screw slide is provided in the screw clamping block, which directly passes through the center of the machine base and is used to place the screws to be used. In this patent, the screws are loaded from the L-shaped screw slide, which cannot ensure that the screws are exactly vertically entered into the center of the machine base, and multiple screws are put in at a time, and there is no obstruction between the multiple screws, so the purpose of installing one screw at a time cannot be achieved.
