The invention relates to a snap joint type lead sealing electronic unsealing device. The snap joint type lead sealing electronic unsealing device comprises a gun body which is divided into a holding cavity, a gun barrel and a bore; a thermal insulation channel composed of ceramic thermal insulation sheets is arranged at the inner wall of the gun barrel, and a trigger is arranged on the communication side of the holding cavity and the bore and movably connected with a first connecting rod; and a second connecting rod is movably connected behind the first connecting rod, the back end of the second connecting rod is movably connected with a fixed shaft which is arranged on a sliding block, and a reset spring is connected to the middle portion of the second connecting rod. The sliding block slides left and right in a sliding way arranged in the bore, a thermal insulation connecting rod connected with a heating pipe is arranged on the front side of the sliding block, and the front end of the thermal insulation connecting rod and the back end of the heating pipe are connected in a clamped manner; and the heating pipe can stretch out and draw back along the thermal insulation channel, and the heating pipe is connected with a switch and an external power circuit. By means of the snap joint type lead sealing electronic unsealing device, a hot melting principle is adopted for melting a seal at a moment so as to achieve the unsealing effect, it can be guaranteed that unsealing operation is completed within three seconds, the snap joint type lead sealing electronic unsealing device is convenient and rapid, the unsealing efficiency is greatly improved, and the self structure of a watch is not damaged.
