Embodiment Construction

[0012] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] A magnetic suction arc-shaped pliers, which is formed by a left half pliers 1 and a right half pliers 7 hinged by a pliers shaft 3; the left half pliers 1 is integrally formed by a left pliers handle 2 and a right pliers head 4; 7 is integrally formed by the right pliers handle 8 and the left pliers head 9; the ends of the left pliers head 4 and the right pliers head 9 are provided with arc-shaped jaws 6 that form a corresponding fit; the left pliers head 4 and the right pliers head The upper and outer sides of 9 are respectively provided with magnetic strips 5, which are in contact with the arc-shaped jaws 6, and transmit the magnetism of the magnetic strips 5 to the arc-shaped jaws 6 for sucking screws and washers.

[0014] The arc radius of the arc jaw 6 is 10mm, the arc height is 3mm, and the chord length of the arc jaw 6 can also b...

Abstract

The invention belongs to the technical field of hand tools, and relates to magnetic arc-jaw tongs. The magnetic arc-jaw tongs are formed by hinging of a left half 1 and a right half 7 via a tong shaft 3. The left half 1 is composed of a left tong handle 2 and a left tong head 4 as a whole, and the right half 7 is composed of a right tong handle 8 and a left tong head 9 as a whole. Each of the left tong head 4 and the right tong head 9 is provided with an arc jaw 6. Magnetic stripes 5 are arranged at positions, close to the arc jaws 6, on the left tong head 4 and the right tong head 9. The arc jaws 6 can reliably clamp screws with various screw heads, matched washers penetratingly arranged on the screws can be attracted via magnetic attraction force, and the screws are mounted, dismounted, picked and placed at deep recesses reliably and efficiently. The magnetic arc-jaw tongs are used for reliably placing the screws in the deep recesses accurately and reliably as well as taking out the screws together with the washers.

Description

technical field [0001] The invention relates to a hand tool, in particular to a magnetic suction arc pliers. Background technique [0002] Screw connection is a commonly used detachable connection in engineering technology. Especially in power engineering and telecommunication engineering, it is often used as line connection. There are two positions of screw connection: prominent and deep. For the assembly and disassembly of hidden screws, because human fingers cannot touch the installation position, when tightening, the nail tail cannot be inserted into the screw hole accurately; when disassembling, the screw cannot be picked up at one time, especially the spring washer and flat washer equipped with the nail head. Hard to get. An effective assembly and disassembly tool is needed for the assembly and disassembly of the deep hidden screws. Contents of the invention [0003] In order to solve the problem of accurate and quick assembly and disassembly of hidden screws and...
