Embodiment Construction

[0009] The nail-holding magnetic head screwdriver includes a magnetic head screwdriver body, and a nail holder is arranged on the magnetic head screwdriver body. The nail holder is looped on the guide ring 2 of the magnetic head screwdriver body taper rod 1 and bonded to the guide ring 2. And the noose 3 that length is greater than the guide ring length constitutes. During specific manufacturing, the guide ring 2 is passed on the screwdriver rod 1 along the flat surface of the flat head screwdriver; The noose 3 is glued on the guide ring 2 that has been installed on the screwdriver rod 1 then. The guide ring 2 is made of high-elastic plastics; the height is 10mm; the inner diameter before loading is less than the diameter of the tapered rod (1); the skin thickness is 2mm; an axial seam is arranged. Noose 3 is made of high elastic latex. The length is equal to the sum of the 2 heights of the guide ring, the head length of the magnetic head screwdriver body, and the length of ...

Abstract

The invention relates to a hand tool, in particular to a nail-holding magnetic head screwdriver. The problem that an existing magnetic head screwdriver cannot absorb and hold copper and aluminum screws and cannot absorb and hold iron screws regularly is solved. The nail-holding magnetic head screwdriver comprises a magnetic head screwdriver body, the magnetic head screwdriver body is provided with a nail-holding device, and the nail-holding device is formed by a guide ring annularly sleeving a cone rod of the magnetic head screwdriver body and a rope sleeve fixedly adhering to the guide ring and having the length larger than that of the guide ring. The guide ring and the rope sleeve are made of elastic materials. The nail-holding magnetic head screwdriver has the advantages that the screws are held reliably, installed and positioned accurately and absorbed conveniently after being dismantled, and the nail-holding magnetic head screwdriver is suitable for installation and dismantling of the screws at the sunken positions.

Description

technical field [0001] The invention relates to a hand tool, in particular to a nail-holding magnetic head screwdriver. Background technique [0002] There are two types of screw mounting positions for electrical products: protruding and recessed. The screw in the recessed position is not easy to identify when installing; it is inconvenient to grasp when removing. People first magnetize the screwdriver head, and use the ferromagnetism of the iron screw to attract the screw for loading and unloading. In recent years, on this basis, a magnetic layer has been coated on the screwdriver head, and a magnetic head screwdriver has been developed, which greatly facilitates the loading and unloading of the screw in the recessed position; but there are still copper-aluminum screws that cannot be held and the holding is not correct. Disadvantages of being on the front line. Contents of the invention [0003] The invention solves the problems that the existing magnetic head screwdri...
