  7. The laser level assembly (10, 11, 1010, 1011, 3010) of claim 6, wherein when the door (2400) is in the closed position, the door blocks the pinion (2061) from disengagement from the rack (2062), and wherein when the door (2400) is in the open position, the door does not block the pinion (2061) from disengagement from the rack (2062).
  8. The laser level assembly (10, 11, 1010, 1011, 3010) of claim 6 or claim 7, wherein the door (2400) is at a top end of the attachment bracket (2230).
  9. The laser level assembly (10, 11, 1010, 1011, 3010) of any preceding claim, wherein the movable bracket (2320) comprises a biasing member that biases the movable bracket away from the attachment bracket (2230) to facilitate movement of the movable bracket relative to the attachment bracket.
  10. The laser level assembly (10, 11, 1010, 1011, 3010) of any preceding claim, wherein the attachment bracket (2230) comprises magnets (227).
  11. The laser level assembly (10, 11, 1010, 1011, 3010) of any preceding claim, wherein the movable bracket (2320) comprises a battery receptacle configured to receive a battery pack (250, 251).
  12. The laser level assembly (10, 11, 1010, 1011, 3010) of any preceding claim, wherein the clutch (2070) comprises a first clutch part (2085) with first teeth (2086) and a second clutch part (2088) with second teeth (2089), wherein the first teeth and second teeth are selectively engaged.
  13. The laser level assembly (10, 11, 1010, 1011, 3010) of claim 12 when directly or indirectly dependent on claim 2, wherein the pinion (2061) is integral with the second clutch part (2088).

Description

The present invention relates to construction tools such as a construction laser level. There are various existing laser levels. It is desired to provide a laser level assembly with a unique construction. US 2021/0285767 describes a laser level system including a laser level, the laser level projecting at least one laser line. The system also includes a bracket on which the laser level is mounted and a battery pack. The bracket includes a battery pack receptacle into which the battery pack is removably coupled. The battery pack powers the laser level. The battery pack has a maximum initial battery pack voltage (measured without a workload) of at least 18 volts. The system also includes at least one electrical conductor which delivers power from the battery pack in the battery pack receptacle to the laser level.
