[0021] See Figures 1 to 10As shown, a toilet brush with replaceable brush head and spherical clamping includes a brush rod 1 and a replaceable brush head 2, a movable guide rod 3 is arranged in the brush rod 1, the brush rod is inserted by an upper rod 11 and a lower rod 12, the lower rod 12 is spliced by a front half rod 121 and a rear half rod 122; a push button 4 for controlling the movement of the guide rod is arranged on the brush rod 1, a long slot 123 is opened on the front half rod 121, a connecting block 41 on the back of the push button 4 passes through the long slot 13 and is fixedly connected with the guide rod 3, and the push button 4 can drive the guide rod 3 to move. A guide ring 13 matched with the guide rod 3 is installed in the brush rod 1, which ensures that the guide rod 3 can move stably and will not shake. A blocking piece 14 is further arranged in the lower rod 12 for limiting the movement of the guide rod 3.
[0022] A brush head mounting hole 5 is opened at the bottom of the brush rod 1, a sleeve 31 is connected at the bottom of the guide rod 3, a spring plate 15 passing through the sleeve 31 is arranged on the inner wall of the brush rod 1, a reset spring 6 is arranged between the spring plate 15 and the upper inner wall of the sleeve 31, the lower part of the sleeve 31 is opened and a brush head clamp support shaft 32 is arranged, below the spring plate 15, brush head clamp fixing shafts 16 are arranged on the inner walls of the front half rod 121 and the rear half rod 122, and the two brush head clamp fixing shafts 16 are coaxially arranged, two symmetrically arranged brush head clamps 7 are rotatably installed on the brush head clamp fixing shafts 16, a recess 71 accommodating the brush head clamp support shaft 32 is opened in the middle of the inner side surface of the brush head clamp 7, and an installation ring 72 cooperating with the brush head clamp fixing shaft 16 is arranged on the top of the brush head clamp 7; the replaceable brush head 2 includes a connecting plate 21, the center of the connecting plate 21 is a hollow hemispherical shape, an upper shell 22 is installed thereon, finally forming a spherical crown body with a height greater than a radius, the inside of the spherical crown body is hollow, a cleaning sponge 23 is fixed to the lower part of the connecting plate 21, and the outer surface of the lower part of the brush head clamp 7 is a spherical surface 73 cooperating with the inner wall of the hollow hemispherical center of the upper shell 22 and the connecting plate 21.
