Laser straight liner
First Claim
1. A laser level, comprising:
- a foundation (1) with at least one battery provided therein,a base (2) with at least one laser projection module (3) mounted thereon,wherein said base (2) and said foundation (1) are connected in a way that allows for 360 degrees rotation of said base relative to said foundation, and wherein one side of said foundation (1) that faces said base (2) is provided with anode and cathode conduction rings (11) that are connected to said battery, and wherein one side of said base (2) that faces said foundation (1) is provided with two contact pieces (21) that connect to said at least one laser projection module (3) and that connect to the anode and cathode conduction rings (11) to provide a conduction-wire-free connection between said laser projection modules (3) and said batteries; and
said laser level further including a columnar cavity in the middle of both said foundation (1) and said base (2), wherein an upper-end shell (22) of said cavity for said base (2) and a lower-end shell (12) of said cavity for said foundation (1) are both made of transparent materials.

Abstract
The utility model relates to a kind of laser straight liner, including a foundation and a base, wherein said foundation is provided with batteries and said base is provided with at least one laser projection module. Said base and said foundation are connected in the way that is 360 degrees rotatable. One side of said foundation that faces said base is provided with the anode and cathode conduction rings that can connect batteries, and one side of said base that faces said foundation is provided with two contact pieces that can connect various laser projection modules and also can touch the anode and cathode conduction rings, thus realizing the conduction-wire-free connection between said laser projection modules and said batteries. This utility model makes said laser projection modules freely rotatable on said foundation, and thus the rotated angle during marking can be accurately controlled, ingenious and reasonable in design and convenient in operation. The lower-end transparent shell of cavity is provided with a cross scale, and the crossing point of said cross scale can be superposed with the intersection projection of the counter-extension lines of the laser beams emitted by various said laser projection modules, thus ensuring a accurate positioning.
