1. The present utility model relates to the technical field of soldering tin bars, in particular to a new type of tin bar.

2. But the tin bars currently used still have the following problems in use:

3. Most of the existing tin bars are covered with plastic film to isolate the air and reduce the oxidation of the outer wall, but the method of covering with plastic film makes it very inconvenient to use, and the film needs to be killed, and the film is torn off without welding. The part that arrives will also be oxidized, resulting in the worse the welding effect of the back of the soldered tin strip, and the torn film cannot be reused, resulting in waste.

Technical implementation elements:

4. The purpose of the new tin item is to overcome the shortcomings of the prior art and provide a new type of tin bar, which effectively solves the deficiencies of the prior art.

5. The new type of tin bar is realized by the following technical solutions: a new type of tin bar, including a storage handle, a strip-shaped sliding hole is opened at the center of the top surface of the storage handle, and an extrusion seat is slidably connected to the inner wall of the storage handle One end of the storage handle is fixedly connected with a clamping sleeve, the side of the clamping sleeve close to the inner wall of the storage handle is fixedly connected with a sealing film sleeve, and the side of the clamping sleeve away from the storage handle is fixedly connected with a film sealing edge , the inner wall of the sealing film sleeve is covered with soldering tin strips.

6. Optionally, a connecting column is fixedly connected to the center of the top of the outer wall of the extrusion seat, a push button is fixedly connected to the top of the connecting column, and the position of the connecting column corresponds to the position of the strip-shaped sliding hole, The diameter of the connecting column is equal to the width of the inner wall of the strip-shaped sliding hole, the connecting column is slidably connected to the inner wall of the strip-shaped sliding hole, the length of the connecting column is equal to the thickness of the inner wall of the strip-shaped sliding hole, and the push button Make full contact with the surface of the outer wall of the storage handle.

7. Optionally, the extrusion seat is a hollow sleeve structure, the top and bottom of the inner wall of the extrusion seat are provided with rounded corners, and the sealing film sleeve passes through the inner wall of the extrusion seat. , the size of the inner wall of the extrusion seat is adapted to the size of the outer wall of the soldering tin bar, the edge of the soldering tin bar near the extrusion seat is a rounded structure, and the size of the inner wall of the sealing film sleeve is the same as that of the soldering tin bar. The dimensions of the outer walls are equal, and the dimensions of the outer wall of the sealing film sleeve are not smaller than the dimensions of the inner wall of the extrusion seat.
