Abstract
The utility model discloses the electric soldering pliers for preventing hands from scalding, which is characterized in that a main plier handle and the front end of an auxiliary plier handle are hinged with a connecting pin through a connecting link; a conductive block is arranged on the main plier handle and the front lateral side of the auxiliary plier handle; a bulge is arranged on one inner side of the conductive block, while a notch is arranged on the other inner side of the conductive block; a tabletting for pressing wires is arranged at the upper part of the bulge; a fixed retaining screw of the tabletting is arranged on the auxiliary plier handle; a notch is arranged at the other side of the conductive block; a contact piece is arranged at the contact part of the conductive block at the front inner side of the main plier handle. The utility model has the advantages of simple structure, convenient use, prevention from scalding hands for long term use, and long service life.
Description
Technical field
The utility model relates to a kind of welding tool, is a kind of electrode holders of scalding one's hand of preventing specifically.
Background technology
Electrode holders are in use owing to clamp the overheated and hot of handle, directly influence operating personnel's condition of work, also influence welding quality, there are problems such as weak point in service life, application number is that 00257197.8 non scalding hand electric welding tongs having belongs to technical scheme preferably, pincers are designed the ventilating duct on the skin around helical form, and its radiating effect is better.But aspects such as its structure still are not too desirable.
Summary of the invention
The utility model mainly solves the heat that electrode holders produce in the welding operation process, the heat that especially directly passes to handle reduces to greatest extent, keeps the long-time technical problem of using non-scald on hand.
The utility model is realized as follows.
The main pincers that the outside is provided with the insulation protection cover and secondary pincers between be connected with connecting pin by connecting rod; pincers are provided with spring support and spring and spring protection cover to the rear end; its front end master clamps between handle and the secondary pincers handle; secondary pincers are provided with conducting block to a side; the conducting block both sides are provided with projection and depression; projection top is provided with the compressing tablet of pushing down lead; and last compressing tablet fixed screw is pushed down lead with secondary pincers; keep the energising of conducting block and lead; the depression of conducting block opposite side mainly is the folder welding rod, and the front end inboard of main pincers handle is provided with contact chip.
That a kind of non scalding hand electric welding tongs having that the utility model provides has is simple in structure, easy to use, use advantages such as non-scald on hand for a long time.
