摘要： A tool includes a barrel, a guiding wire, and an electrically conductive member. The barrel is made of electrically conductive material. The guiding wire is disposed in the barrel. The barrel and the guiding wire are directly or indirectly connected to two opposite electrodes of a power source. The electrically conductive member is connected to an outer periphery of the guiding wire and is electrically connected to the guiding wire. The electrically conductive member is disposed between the barrel and the guiding wire and is spaced from the barrel. When the power source is activated, an electric arc is generated between the electrically conductive member and the barrel.

摘要： A blowtorch includes a casing and a control unit. The control unit includes an activate button and a lock button. The lock button is switchable between a first lock position and an intermediate position, or between the intermediate position and a second lock position. The activate button is switchable between a standby position and an activation position when the lock button is in the intermediate position. The lock button contacts the activate button and restricts the activate button to hold in the activation position when the activate button is in the activation position and the lock button is in the first lock position or the second lock position.

摘要： A fuel-burning device includes a container defining a receptacle and having an opening which is at an end of the receptacle. The opening has a first width. The fuel-burning device also includes a fixing mechanism mounted in the container through a fixing member. The fixing member has an end resiliently fixed on a periphery of the receptacle. The fixing member is radially compressible. When the fixing member is not compressed, the end thereof has a second width which is greater than the first width. The end of the fixing member is compressible to a third width which is smaller than the first width.
