Description

Locking assembly and electric tool

Technical Field

The present disclosure relates to a locking assembly and a power tool.

Background

The prior art tamper generally uses a four-stroke internal combustion engine as its power component. However, the internal combustion engine uses fuel oil as fuel, and has great pollution. Motorized replacement of the power components of the tamper is currently a trend.

In electric tamper machines, an electric motor and a battery pack for supplying electric power to the motor are typically included.

Thus, unless otherwise indicated, features of the various implementations/embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concepts of the present disclosure.

The use of cross-hatching and/or shading in the drawings is typically used to clarify the boundaries between adjacent components. As such, the presence or absence of cross-hatching or shading does not convey or represent any preference or requirement for a particular material, material property, dimension, proportion, commonality between illustrated components, and/or any other characteristic, attribute, property, etc. of a component, unless indicated. In addition, in the drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. While the exemplary embodiments may be variously implemented, the specific process sequences may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in reverse order from that described. Moreover, like reference numerals designate like parts.

When an element is referred to as being "on" or "over", "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements present. For this reason, the term "connected" may refer to physical connections, electrical connections, and the like, with or without intermediate components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "under … …," under … …, "" under … …, "" lower, "" above … …, "" upper, "" above … …, "" upper "and" side (e.g., as in "sidewall") to describe one component's relationship to another (other) component as illustrated in the figures. In addition to the orientations depicted in the drawings, the spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below … …" may encompass both an orientation of "above" and "below". Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Fig. 5 is a schematic structural view of a second fastener according to one embodiment of the present disclosure. Fig. 6 is a schematic view of another angular configuration of a second fastener according to one embodiment of the present disclosure.

As shown in fig. 1 and 2, the second fastening member 920 is connected to the first fastening member 910 and is capable of rotating along a first axis relative to the first fastening member 910.

That is, the locking assembly 900 of the present disclosure reduces space occupation and solves the technical problems in the related art by dividing the prior art fasteners into two and enabling relative rotation between the two fasteners, thereby achieving folding between the first fastener and the second fastener.

As shown in fig. 5 and 6, the second fastening part 920 includes a hand-held part 921 such that an external force is applied to the second fastening part 920 through the hand-held part 921 during a locking process and an unlocking process, wherein the external force may include a locking force, which is a force applied toward the first member, and an unlocking force, which is a force applied away from the first member.
