Abstract

The utility model discloses a telescopic pistol welding tongs in which the shell is pistol-shaped. A cone-shaped tube is arranged on the front end of the external pistol shell. The symmetric guide grooves are arranged on the external pistol shell of the cone-shaped tube rear. The back end of the external pistol shell is provided with a welding line input pipe. A telescopic frame controlled through a spring is arranged inside the pistol in which the front end is provided with the symmetric connection columns working with the guide groove of the external pistol shell. A wiring pipe provided with a cone-shaped pipe fitting is fixed inside the cone-shaped pipe through a screw. The symmetric upper and lower clamping plates are installed and combined inside the gap between the inner wall of the cone-shaped pipe and the con-shaped pipe fitting, in which the rears are respectively provided with pin holes working with the connection column of the telescopic frame. A positioning groove arranged above the trigger fixed with the telescopic frame works with the button of the handle. When the utility is used, the handle is not hot, moreover the actual utilization of the welding strip can be improved and the welding strips can be saved as well.

Description

Telescopic non-scald on hand pistol electrode holders

Technical field

The utility model belongs to the improvement of electrode holders structure, particularly telescopic non-scald on hand pistol electrode holders.

Background technology

Traditional electrode holders are that soldering turret is connected as a single entity " one " font with handle, and the electrode holder line passes through from handle.When longer, the heat that the electrode holder line produces scalds one's hand handle in weld interval.In addition, traditional electrode holders use the utilization rate of welding rod lower.Be example with the welding rod that uses J422 type, φ 3.2mm, the total length of single welding rod is 350mm, and its maximum effectively utilizes length to be 335mm, and the actual length of using generally is about 290mm-310mm, on average uses length to be 300mm.Like this, the welding rod practical efficiency is 89.4%, wastes bigger.

Summary of the invention

The purpose of this utility model is to provide a kind of telescopic non-scald on hand pistol electrode holders, handle non-scald on hand in use, but also can improve the practical efficiency of welding rod, save welding rod.

The purpose of this utility model is achieved in that a kind of telescopic non-scald on hand pistol electrode holders, comprise fip holder and handle, the electrode holders shell that is made of insulating materials is a pistol-shaped, leading section at body of a gun shell is being provided with conical pipe, the gathering sill of symmetry is being set on the body of a gun shell at conical pipe rear portion, electrode holder line inlet wire pipe is being set in the rear end of body of a gun shell, spring controlled flexible framework is being set in body of a gun cavity, flexible framework front end is being provided with the joint pin of symmetry and is matching with gathering sill on the body of a gun shell, in conical pipe by bolt affixed have a wire barrel of tapered tube head, cooperate in the gap between the tapered tube head of conical pipe inwall and wire barrel and be installed with being much of, the pin-and-hole that its rear section of lower plate is not provided with matches with the binding post of flexible framework, and the locating slot that the trigger that is fixed together with flexible framework is provided with on it matches with the button that the handle upper spring is controlled.

When using the utility model, the electrode holder line is penetrated from the inlet wire pipe, the electrode holder line is connected on the wire barrel.Make clamping plate be retracted in the conical pipe fully and open by trigger squeeze, press the button, make button snap in the locating slot of trigger, this moment, trigger was locked.Welding rod is put into upper and lower clamping plate, slightly press earlier trigger squeeze, make the draw-in groove release button of trigger, spring controlled button ejects draw-in groove, spring promote flexible framework drive upper and lower clamping plate along the gap between the tapered tube head of conical pipe inwall and wire barrel to front slide, close up the welding rod head-clamp tight, and more than the release 15mm with welding rod, thereby use welding rod as much as possible.After welding rod had welded, cocking made upper and lower clamping plate retraction and opens mouth, withdraws from the welding rod head.During as the electric welding end-of-job, cocking presses the button, and upper and lower clamping plate retraction is positioned in the conical converging of insulating materials formation.Like this, electrode holders can be placed on the work optional position, and under the situation of powered-down not, soldering turret can not struck sparks yet, and is in state of insulation.Because the electrode holder line penetrates in the body of a gun cavity from the inlet wire pipe level on top, and the electrode holder line is separated with handle, the electrode holder line no longer passes from handle, when therefore working, holds handle and does not have hot problem.

Subordinate list is the contrast of the utility model product and original product serviceability.

Subordinate list

The utility model has also improved the practical efficiency of welding rod, saves welding rod, and is easy to use, safe and reliable.Of the present utility modelly be shaped to imitative pistol-shaped, not only moulding, novel structure are attractive in appearance, and the hand-holding part when having changed operation simultaneously and hold mode makes operator's feel very comfortable, and makes welding become more flexible.
