The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It will be appreciated by those skilled in the art that features from the examples and embodiments described below may be combined with each other without conflict.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Words such as "upper," "lower," "front," "rear," and the like, which indicate orientation or positional relationships, are used solely to facilitate the description of the invention and to simplify the description, and do not indicate or imply that the referenced devices/elements must have a particular orientation or be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention.

The utility model provides a pair of electric tool battery package release mechanism, as shown in fig. 1-3, wherein this electric tool includes electric tool casing 8 and battery package 7. The upper end side of the battery pack 7 is provided with a battery pack groove. The housing 8 is provided with a locking member 6, the locking member 6 has two locking ends, a rotating shaft 9 is arranged between the two locking ends, and the rotating shaft 9 is relatively rotatably fixed in the housing 8. Locking piece 6 can rotate into battery package recess and carry on spacingly to the battery package, also can rotate out battery package recess and carry out the unblock to the battery package.

The housing is provided with guide ribs 4, and the guide ribs 4 are arranged in a direction parallel to the battery pack 7. The locking mechanism further includes a switch member 3, which switch member 3 is engageable with the guide rib 4 and is movable thereon in a direction parallel to the battery pack 7. The switch member 3 is provided with a switch groove 10 opposite to the groove on the battery pack 7, and the switch groove 10 is matched with the locking member 6. The preferred adoption of this embodiment is equipped with two battery package recesses on the battery package, switches and is equipped with two switching grooves on the piece, and the arbitrary end of two locking ends of locking piece all simultaneously with the battery package recess with switch the groove fit, and switch in piece and the locking piece the fitting surface in groove and switch the piece and the recess fitting surface of battery package all be located the homonymy of locking piece rotation axis. A second elastic member 5 is arranged between the locking member 6 and the switching member 3, and the second elastic member 5 is in a compressed state and can press and hold the locking member 6 in a locking position.

The unlocking mechanism further comprises a switch button 2, which switch button 2 is rotatably mounted on the housing 8. The switch button 2 has an operating end for the switch button and a mating end for mating with the switch 3. The rotation axis 11 of the switch button 2 is located between the operating end of the switch button 2 and the other end cooperating with the switch 3.

The engaging end of the switch button 2 abuts against the switch member 3 and can exert a force on the switch member in a direction opposite to the direction of the elastic force exerted by the second elastic member 5 on the locking member 6, i.e. the switch member 3 is restricted from moving in a direction away from the operating end of the switch button. A first elastic element 1 is arranged between the operating end of the switching button 2 and the shell 8, and the first elastic element 1 is in a compressed state.

In the locking state, the locking piece is clamped in the groove of the battery pack and clamped in the switching groove of the switching piece, the switching piece is kept at a relatively stable position under the action of the second elastic force and the matching end of the switching button, and the switching button is kept at a stable position under the action of the first elastic force and the switching piece at the moment, so that the battery pack is reliably locked.

When the unlocking is carried out, the switching button is pressed to compress the first elastic piece, the switching button rotates around the rotating shaft, and the other end of the switching button matched with the switching piece generates an acting force for overcoming the elastic force of the second elastic piece, so that the switching piece horizontally moves towards the direction close to the switching button. The horizontal movement of the switching piece enables the locking piece to rotate around the rotation shaft of the switching piece, and finally, the part, matched with the groove of the battery pack, of the lower part of the locking piece rotates to be separated from the groove of the battery pack, so that the locking of the battery pack is released, and the battery pack can be detached from the electric tool. After the switching button is loosened, the switching button is reset under the action of the first elastic piece, and after the acting force applied to the switching piece is cancelled by the matching end of the switching button, the switching piece and the locking piece automatically recover to the locking state under the action of the second elastic force.

So the utility model provides an electric tool battery package release mechanism, this locking mechanical system simple operation and easily installation.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
