QUICK-CHANGE ASSEMBLY FOR HEAD AND BODY OF MULTIFUNCTIONAL POWER TOOL AND MULTIFUNCTIONAL POWER TOOL Russian patent published in 2024 - IPC B25F3/00 B25F5/02 B25D11/02 B25D17/08 B25B23/00 B23B45/02 B23B31/02 

FIELD: hand-held power tools.

SUBSTANCE: invention relates to a quick-detachable unit for a head and a body of a multifunctional electric tool. Assembly comprises tool body (100), torsion ring (200) located in the body, which axis is parallel to the socket axis, cartridge head (300) having the possibility of disconnection through torsion ring (200) connector (220), part (400), having the ability of elastic deformation and made with possibility of returning to initial position after rotation of torsion ring (200), retainers (500) of head (300), made with possibility of movement along straight line between first and second positions in direction perpendicular to axis of torsion ring (200), during rotation of torsion ring (200). In the first position, the locking element of each retainer (500) of head (300) is located on the movement path of the clamping platform of head (300) in connector (220), and in the second position, the locking element of each retainer (500) of head (300) is located outside the trajectory of movement of the clamping platform.

EFFECT: assembly design provides a smaller and simpler force applied manually for unlocking, design also provides for locking of butt contact for high stability and reduction of vibration during operation.
