The electric glue gun 100 also has a constant speed mode, and when the electric glue gun 100 is in the constant speed mode, the user can operate the trigger 16 to cause the electric glue gun 100 to output a predetermined, constant power. Specifically, the electric glue gun 100 is provided with a memory chip 18 having a memory function, as shown in fig. 7, the memory chip 18 is electrically connected to the speed regulating switch 17, and the memory chip 18 is also connected to a memory switch 181. When the user operates the trigger 16 to continue operation and needs to continue operation at a certain fixed output power, the memory switch 181 can be activated when the electric glue gun 100 is at that output power. At this time, the memory chip 18 can obtain the output signal of the electric glue gun 100 at the output power, and can control the output power of the electric glue gun 100 according to the signal. When the user starts the electric glue gun 100 again for operation, the electric glue gun 100 can directly enter the preset output power of the memory chip 18 and output at a constant speed only by touching the trigger 16. At this time, the speed regulation function of the trigger 16 is disabled, and when the user needs to enter the speed regulation mode again, the electric glue gun 100 automatically enters the speed regulation mode only by operating the memory switch 181 again.
