A driving device of caulking gun includes a housing, a driving assembly, a threaded rod, and a transmission assembly. The housing defines an axial direction. The driving assembly is disposed on the housing and includes a motor assembly and a driving gear. The motor assembly and the driving gear are linked-up to rotate simultaneously. The threaded rod is slidably disposed on the housing and is nonrotatable with respect to the housing. The threaded rod is formed with a spiral groove. The transmission assembly is arranged in the housing and includes a transmission sleeve and a plurality of abutting members. The transmission sleeve is sleeved onto the threaded rod and is radially formed with a plurality of through holes. The abutting members are received in the through holes respectively. The transmission sleeve and the driving gear are linked-up.

A dispenser for compound-containing containers includes a receiving chamber for a container; at least one push rod displaceable relative to the receiving chamber; a motor for moving the at least one push rod; a control unit for controlling the motor; a main switch; an operation selection switch for setting a selected amount of the compound to be dispensed in one application run; and a sensor configured to detect movement of the push rod. The control unit is configured to store a missing amount of the compound when one application run is interrupted. The dispenser dispenses the missing amount of the compound when the main switch is actuated for finishing the interrupted application. If an application run gets interrupted, for example due to empty battery, the missing amount of the compound is dispensed instead of the preselected amount. This function allows the application to proceed without additional chemical or compound wastage.

A dispenser for compound-containing containers includes a receiving chamber for a container; at least one push rod displaceable relative to the receiving chamber; a motor for moving the at least one push rod; a control unit for controlling the motor; a main switch for activating the motor; and an operation selection switch for switching between different operation modes and having a discard position. The control twit is configured to dispense a predetermined discard amount of the compound when the operation selection switch is set to the discard position and the main switch is triggered. The dispenser provides an automated discard function, which helps the user to discard the correct amount of compound before starting normal applications. With the dispenser, a procedure of initializing a compound-containing container is improved, to increase the security of the application.

A trigger assembly can be used to activate a motor controller to cause a motorized device to respond in a certain manner. For example, when the motorized device is a power tool, based on a number of pulls of the trigger, the motor controller can run the power tool in a forward direction or a reverse direction. A power tool running in the forward direction can receive a tap of the trigger. A timer can be started upon detecting the pull of the trigger. Another tap of the trigger can be detected within a time period determined based on the timer. The power tool can be forced to perform a reverse operation when the other tap f the trigger is within the time period.
