Tool pliers

Abstract

The invention relates to tools of the field of machinery manufacturing, in particular to a pair of tool pliers. The pair of tool pliers comprises a pliers mouth portion and a hand holding portion, wherein the hand holding portion comprises a left handle and a right handle, an inner cavity is formed in any one of the handles, an electricity detection device is stored in the inner cavity, and can stretch out outwards and contract, the electricity detection device comprises a contact terminal and a detection device body connected to the rear end of the contact terminal, the detection device body comprises a first resistor, a luminous element, a second resistor, a conducting element and a hand touch electrode, the first resistor, the luminous element, the second resistor, the conducting element and the hand touch electrode are connected in series in sequence, and the hand touch electrode is connected with a conducting contact arranged on the outer side of the hand holding portion through wires. According to the pair of tool pliers, a test pencil and a pair of tool pliers are integrated, the electricity detection portion is arranged on the tool pliers body in a telescopic mode, and is stored in the cavity of the handle of the tool pliers body when not used, and the pair of tool pliers has good practicability.

Description

technical field [0001] The invention relates to tools in the field of machine manufacturing, in particular to a tool pliers. Background technique [0002] Tool pliers are a tool that is often used in the mechanical field to rotate and fasten bolts, nuts and clamping objects. There are many nut connectors on many large electrical equipment. Large electrical equipment is in disrepair due to aging equipment. The reason is that the leakage of internal wires often occurs. At present, when disassembling and assembling these large electrical equipment, the current tool pliers generally require an electrician to use a measuring point pen to measure the power of the equipment shell and tightening nut, and can arrange after eliminating potential safety hazards. Relevant personnel disassemble and repair the equipment, and the work efficiency is low. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a device that combines the function of a voltage m...

[0002] Tool pliers are a tool often used in the mechanical field to rotate and fasten bolts, nuts and clamp objects. There are many nut connectors on many large electrical equipment. Due to the aging of equipment, large electrical equipment has been in disrepair for a long time. Because of the reason, the phenomenon of internal wire leakage often occurs. When disassembling and assembling these large electrical equipment, the current tool pliers generally require electricians to use a measuring point pen to measure the current of the equipment shell and fastening nuts, and then arrange them after eliminating potential safety hazards. Relevant personnel disassemble and overhaul the equipment, and the work efficiency is low
