Moreover, the elastic element 320 may include an expansion spring clamped in the lock-catch retaining groove 3122, one end of the expansion spring abuts against the retaining protrusion 201, and the other end abuts against the lock-catch block body on the side wall of the shaft-cover retaining groove 202 with the retaining hole 204. The telescopic spring can be limited through the lock catch limiting groove 3122 formed in the lock catch connecting block 312, and the telescopic spring is prevented from deviating or separating in the using process. In addition, a connection limiting column 318 is further protruded from the bottom wall of the lock latch limiting groove 3122, and one end of the retractable spring can be sleeved on the connection limiting column 318. The elastic member 320 may be a retractable elastic structure such as a leaf spring or an elastic shaft, in addition to a retractable spring.

In addition, the resilient attachment structure 300 may include latch cover structures 330 hinged to opposite slot sidewalls of the shaft cover recess 222. Moreover, the latch cover structure 330 may include a latch cover plate 332 covering the shaft cover groove 222 and covering the shaft cover limiting groove 202, and a latch shifting block 334 protruding from one side of the bottom of the latch cover plate 332, wherein the latch shifting block 334 is correspondingly abutted against the end of the latch connecting block 312 near the limiting hole 204. The shaft cover groove 222, the shaft cover limiting groove 202, the latch connecting piece 310, the elastic piece 320 and the like can be covered by hinging the latch cover structure 330 on the shaft cover groove 222 so as to hide and protect the parts, and meanwhile, the latch connecting piece 312 is conveniently pressed by the latch shifting block 334 of the latch cover structure 330, so that the latch 314 of the latch connecting piece 310 stretches and retracts to be separated from the latch connection with the upper floor brush cover 112, and the unlocking of the brush shaft cover 200 and the upper floor brush cover 112 is realized. That is, by rotating the lock cover 332, the lock dial 334 presses the lock connecting block 312, so that the elastic member 320 is compressed, thereby contracting the lock connecting block 312 and the lock tongue 314 thereof. Furthermore, the latch driver 334 abuts against the latch connector 312, so that the elastic force of the elastic member 320 can act against the latch driver 334 and the latch cover 332, and the latch cover 332 can be automatically reset when the rotation of the latch cover 332 is released.

Moreover, the latch cover structure 330 may include a cover plate rotating shaft 336 protruding from two opposite sides of the latch cover plate 332; meanwhile, two opposite side walls of the shaft cover groove 222 are respectively provided with a shaft hole, so that the two cover plate rotating shafts 336 are correspondingly arranged in the two shaft holes one by one, and the lock catch cover plate 332 can stably and reliably rotate in the shaft cover groove 222.

Moreover, the latch cover structure 330 may include a latch shifting block 334 obliquely disposed on each of two sides of the bottom of the latch cover 332, a latch wedge 316 is correspondingly obliquely disposed on each of two sides of the latch connecting block 312 close to the limiting hole 204, and the two latch shifting blocks 334 are abutted against the two latch wedges 316 one by one. The locking wedge 316 extends from the direction of the bolt 314 to the direction of the elastic element 320; correspondingly, the lock catch shifting block 334 extends obliquely downward from the direction of the elastic member 320 to the direction of the lock tongue 314. When the side of the latch cover plate 332 away from the latch driver 334 is lifted, the latch cover plate 332 rotates around the cover plate rotating shaft 336, so that the latch driver 334 on the other side of the latch cover plate 332 presses downward, at this time, the latch driver 334 presses downward along the inclined surface of the latch wedge 316, so that the latch wedge 316 moves in a direction away from the limiting hole 204 and the latch hole 102, that is, the latch connector block 312 moves in a direction close to the elastic member 320 to press the elastic member 320 to compress the elastic member, so that the latch 314 at the end of the latch connector block 312 retracts from the limiting hole 204 and the latch hole 102, that is, the latch connector 310 is separated from the floor brush upper cover 112, thereby unlocking the floor brush upper cover 112 and the brush shaft cover 200. And after the brush shaft cover 200 is unlocked, the brush shaft cover 200 can be removed from the upper cover 112 of the floor brush, and then the brush shaft assembly 120 can be removed from the main body 110 of the floor brush for cleaning. After the brush shaft assembly 120 is cleaned, the brush shaft assembly 120 may be installed in the floor brush body 110.

In addition, the brush shaft cover 200 may include a shaft cover installation portion 210 formed in an arc shape, and a shaft cover connection portion 220 protruded from a side of the shaft cover installation portion 210, wherein the elastic connection structure 300 is disposed on the shaft cover connection portion 220, and the shaft cover installation portion 210 is covered above the brush shaft assembly 120.
