A tool device comprises a first module and a second module that can be detached from the first module, the first module having a receptacle and the second module having an insertion part that can be inserted in the receptacle along an insertion axis. The insertion part can be rotated in the receptacle about the insertion axis between a locked position and an enabled position, the receptacle having a first projection and the insertion part having a second projection. In the locked position, the second projection engages behind the first projection in the direction of the insertion axis, and in the enabled position, the first projection enables the second projection to pass in the direction of the insertion axis, the receptacle preventing an activation of the tool device in an initial position and allowing activation of the tool device in a pressed-on position.

Tool device

Tool device&#x2014;with module attachments

The invention relates to a device for driving a securing element into a substrate, having a mechanical energy store for storing mechanical energy; an energy transmitting element for transmitting energy from the mechanical energy store to the securing element; an energy transmitting device for transmitting energy from an energy source to the mechanical energy store; a housing with a first and a second housing part, said first housing part being connected to the second housing part in order to form an interior between the first and second housing part, the mechanical energy store being arranged in said interior; and an intermediate element, by means of which the mechanical energy store can be secured to the first housing part at least temporarily while energy is stored in the mechanical energy store.

Driving-in device

A fastener driving tool comprises a hand-held casing having a movable and drivable energy transmission element including a driving member, wherein the driving member acts to drive a fastener, a locking element, and a sensor member for determining an operational state of the fastener driving tool, wherein a driving process is released only if the operational state prevails, wherein the locking member is arranged in a locking manner in a path of the energy transmission element if the non-operational state prevails, wherein, once a driving process has been triggered, the locking member can stop the energy transmission element.

Fastener driving tool with safety lock

The invention concerns a driving tool comprising a motor, in particular, an electric motor, a gas spring with an elastically compressible gas volume, and a firing piston, wherein the gas spring can be tensioned via a tensioning device with the motor, so as to accelerate after a release from a tensioned state the firing piston in a firing direction, wherein at least one part of the tensioning device is located within the gas volume of the gas spring.

Fastener driving tool

According to one aspect of the application, a device for driving a fastening element into a substrate has an energy-transfer element for transferring energy to the fastening element. The energy-transfer element can move preferably between a starting position and a setting position, wherein the energy-transfer element is located, before a driving-in procedure, in the starting position and, after the driving-in procedure, in the setting position. According to another aspect of the application, the device comprises a mechanical-energy storage device for storing mechanical energy. The energy-transfer element is then suitable preferably for transferring energy from the mechanical-energy storage device to the fastening element.
