Description

Laser level meter Technical Field The present application relates to laser levels, and more particularly to laser levels having a rotating base. Background The laser level is an optical level and plumb alignment device, and generally comprises a housing, a plumb body suspended in the housing, and a laser generating part mounted on the plumb body. Because operators need to make level with different height references in the operation process, height adjusting components such as a tripod and the like are configured for use in many cases. However, users often need to prepare the adaptive height adjusting parts by themselves, so that the users often have inconvenience, and laser level meters with bases (with height adjusting functions) are also appeared on the market, but the products are large in size and inconvenient to store and carry. Accordingly, there is a need for improvements to optimize the technical problems existing in the prior art. Disclosure of Invention The application aims to solve the problem that a laser level with a base is inconvenient to store and carry. In order to solve the technical problems, the application provides a laser level, which comprises a shell, a laser generator, a base and a base, wherein the laser generator is positioned in the shell and can generate a lower plumb beam emitted to the outside of the shell and/or a laser surface containing the lower plumb beam, the base is pivotably assembled to the shell and provided with an attachment part for external installation, the shell is provided with a lower opening for the lower plumb beam and/or the laser surface to emit, a yielding space is formed below the lower opening and above the bottom surface, the base can rotate between a first position and a second position relative to the shell, and when the base is positioned at the first position, the attachment part is positioned in the yielding space.
