Insulated picking clamp forged with pure copper

Abstract

An insulated picking pliers made of pure copper, including an upper jaw and a lower jaw. There is a channel inside the clamp to accommodate the wires. Fixing frames are installed on both sides of the lower jaw respectively. A hinge shaft is installed on the fixing frame. The upper jaw is installed on the hinge shaft. The rear end of the upper jaw is a pressure handle. A return spring set is arranged between the jaws; the advantages of the present invention are ingenious and reasonable, beautiful structure, durable, convenient operation, safe and reliable, good insulation performance, and the advantages of continuous operation without burning hands.

Description

technical field [0001] The invention relates to the technical field of welding tooling, in particular to an insulated picking pliers forged from pure copper. Background technique [0002] Strain picking pliers are hand-held insulating appliances used to hold and manipulate electrodes during electrode arc welding and to ensure electrical connection with electrodes. It can be used to quickly install the welding rod and remove the remaining welding rod stub, and clamp the welding rod at any specified position, so that the welding rod can be welded to only 50mm long. However, since the bacteria picking forceps mainly rely on the spring force to hold the welding rod, there are many problems due to the weak clamping during use, such as: overheating occurs, oxides are formed on the contact surface, resulting in unstable conduction current, and bacteria picking The fast heating of the clamps will cause damage, and the burning sensation in the hands of the operator will make people ...

Problems solved by technology

However, since the bacteria picking forceps mainly rely on the spring force to hold the welding rod, there are many problems due to the weak clamping during use, such as: overheating occurs, oxides are formed on the contact surface, resulting in unstable conduction current, and bacteria picking Fast heating of the forceps will cause damage, and the burning sensation of the operator's hands is strong, which makes people tired and uncomfortable

The hinged connection between the upper jaw and the lower jaw of the strain picking forceps is not very firm, and the situation that the upper jaw deviates from the lower jaw often occurs, which brings a lot of inconvenience to people's operation, and the traditional strain picking pincers are harmful to the human body. There are many defects in the protection, the handle is easy to conduct electricity, and there is often an electric shock
