[0002] A laser projector is a machine that emits vertical and / or horizontal visible lasers and marks horizontal or vertical lines on the target surface. The laser lines can be accurately projected onto the work object, making the construction process more convenient and time-saving.

[0003] However, in the prior art, the casing of the laser line projector currently on the market needs to be provided with a slide groove so that the sliding switch can be connected to the internal clamp lock through a connecting rod or a screw.

In addition, the position of the laser line projector needs to be moved when the worker is working, and the traditional equipment does not have an anti-accidental touch mechanism. Therefore, when the worker moves, he accidentally touches the switch, causing the casing to separate from the laser line projector, thereby causing the laser line projector to fall, resulting in damage to the laser line projector.

[0034] Working principle:

[0035] When in use, first align the body 1 of the line thrower with the groove on the casing 2 and install it on the casing 2. At this time, the body 1 of the line thrower can be fixed on the casing 2 through the locking mechanism 4. By manually pushing the sliding plate 41 in the sliding groove 46, the sliding plate 41 is forced to drive the main magnet 42 to move. A secondary magnet 43 attracted to the main magnet 42 is provided inside the casing 2, and the secondary magnet 43 is installed on the lock 44. Therefore, when the main magnet 42 moves, the secondary magnet 43 attracted to the main magnet 42 is forced to move synchronously, thereby making the lock 44 slides on the casing 2, and when the lock 44 moves, it contacts the clamping foot 45, thereby driving the clamping foot 45 to move, and under the continuous movement of the sliding plate 41, the sliding plate 41 slides to the locking position, and the protrusion on the lock 44 slides into the groove on the casing 2, thereby limiting the position of the lock 44, and when the lock 44 moves to the groove of the casing 2, the clamping foot 45 synchronously locks the line casting instrument body 1, at this time the line casting instrument body 1 and the casing 2 complete the locking work, and the line casting work can be carried out at this time.

[0036] When the line throwing instrument body 1 is working, in order to prevent the worker from accidentally touching the locking mechanism 4 and causing the line throwing instrument body 1 to fall off from the casing 2, the blocking mechanism 3 can be used to block the sliding plate 41 in the locking mechanism 4. When the worker completes the locking mechanism 4, the sliding shell 34 slides upward, forcing the lower block 33 on the sliding shell 34 to contact the upper block 32 of the upper cover 31, and at the same time, the trigger 37 is manually pressed to force the trigger 37 to drive the rotating drum 312 to rotate. The rotating drum 312 is fixed to the casing 2 through the fixed shaft 313, so as to limit the rotating drum 31 2, a torsion spring 310 is fixed on the rotating cylinder 312, so when the rotating cylinder 312 rotates, the torsion spring 310 is compressed, and the rotating limit plate 38 forces the limit plate 38 to move to the bottom of the fixed block 39, at which time the pressure on the trigger 37 can be released, and the compressed torsion spring 310 releases its elasticity at this time, forcing the rotating cylinder 312 to drive the trigger 37 to reset and contact the limit plate 38, thereby limiting the position of the limit plate 38, thereby limiting the position of the sliding shell 34, so that the sliding shell 34 covers the sliding plate 41.

[0037] When the line casting work is completed and the line casting instrument body 1 needs to be separated from the casing 2, the trigger 37 is pressed again to force the trigger 37 to release the limit plate 38. At this time, the limit plate 38 simultaneously releases the restriction on the fixed block 39, so that the sliding shell 34 can slide downward. At the same time, a top spring 36 is fixed on the fixed block 39. Therefore, when the fixed block 39 is about to contact the baffle 35, the elastic action of the top spring 36 forces the sliding shell 34 to slow down the downward speed to reduce the impact of the sliding shell 34 on the baffle 35. At this time, the handle on the upper cover 31 can be pulled to lift the upper cover 31 upward, forcing the sliding plate 41 to be exposed. At this time, the sliding plate 41 can be manually pushed to separate the line casting instrument body 1 from the casing 2.
