[0047] The implementation principle of a multifunctional breaker hammer that is easy to disassemble and assemble in an embodiment of the present application is as follows: when crushing, first insert the steel chisel 300 into the sliding hole 131, and then rotate the drive ring 420, the drive ring 420 drives the drive block 430 to rotate, and the drive block 430 drives the limit rod 410 to be inserted into the limit groove 310; at this time, the locking spring 442 drives the locking rod 441 to slide, and the locking rod 441 is inserted into one of the locking grooves 133, thereby reducing the rotation of the drive ring 420 during operation.

[0048] When the driving ring 420 rotates, the protrusion is driven to rotate at the same time. As the protrusion rotates, the protrusion is separated from the circular plate 650, and the vibrating spring 630 releases its elastic force to restore the free state and drives the circular plate 650 to approach the driving ring 420.

[0049] When the driving ring 420 rotates, the rotating ring 522 is driven to rotate through the synchronous rod 524, and the rotating ring 522 drives the winding rope 523 to squeeze the dust cover 510, so that the dust cover 510 shrinks and fits with the steel drill 300, reducing the entry of dust during the working process.

[0050] When the crushing work is in progress, the hydraulic cylinder drives the steel drill 300 to slide and vibrate to complete the crushing. During the sliding process of the steel drill 300, the dust cover 510 is driven to slide, and the dust cover 510 and the steel drill 300 are displaced. The dust cover 510 scrapes off the dust attached to the surface of the steel drill 300, and the vibrator spring 630 drives the dust cover 510 to reciprocate to further scrape off the dust.

[0051] When removing the steel bar 300, the pulling block is pulled, the locking rod 441 is pulled out of the locking groove 133, and then the driving ring 420 is rotated in the opposite direction. The driving ring 420 with the protrusion 620 squeezes the circular plate 650, so that the circular plate 650 drives the fixing rod 610 to slide, so that the dust cover 510 further scrapes off the dust on the steel bar 300; then the steel bar 300 is pulled out, and the limit groove 310 of the steel bar 300 abuts against the chamfer of the limit rod 410, so that the limit rod 410 retracts into the sliding hole 132.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
