[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 5 As shown, the utility model provides a toothbrush that is easy to replace the brush head, including a brush head 1 and a sleeve 8, a brush handle 7 is slidably provided in the sleeve 8, and a sliding clamping mechanism is provided between the two sides of the brush handle 7 and the inner wall of the sleeve 8, an insertion groove 3 is provided at one end of the brush handle 7, a support plate 2 is fixed to one side of the brush head 1, and the support plate 2 is inserted in the groove 3, a slot 4 is provided on the side wall of the groove 3, an inserting plate 5 is fixed to one side of the support plate 2, and the inserting plate 5 is inserted in the slot 4, and the support plate 2 can be horizontally limited by inserting the inserting plate 5 in the slot 4, and a limiting mechanism 6 is provided between one side of the inserting plate 5 and the brush handle 7, and the inserting plate 5 can be limited by the limiting mechanism 6, so that the support plate 2 can be limited, so that the brush head 1 can be installed on the brush handle 7.

[0021] Among them, an anti-slip cover 9 is provided on one side of the sleeve 8, which can prevent the hand from slipping when holding the sleeve 8 for brushing teeth.

[0022] A collar 10 is fixed at one end of the sleeve 8, and the toothbrush can be conveniently hung by the collar 10.

[0023] Among them, the sliding clamping mechanism includes an arc-shaped slide groove 11 and an arc-shaped rubber protrusion 12. The arc-shaped slide groove 11 is opened on both sides of the brush handle 7, and the arc-shaped rubber protrusion 12 is fixed on both sides above the inner wall of the sleeve 8, and the arc-shaped rubber protrusion 12 is inserted in the arc-shaped slide groove 11. By pulling the brush handle 7 to slide in the sleeve 8, when the brush handle 7 moves to a suitable position, the brush handle 7 is rotated again. At this time, the arc-shaped rubber protrusion 12 will be separated from the arc-shaped slide groove 11 and come into conflict with the outer wall of the brush handle 7, so that the brush handle 7 can be clamped and limited. In this way, the length of the brush handle 7 can be adjusted, which is convenient for different people to use.

[0024] Among them, the limiting mechanism 6 includes a limiting hole 62 and an annular plate 61. The limiting hole 62 is opened on one side of the plug plate 5. The annular plate 61 is fixed to the side wall of the brush handle 7. A slide plate 63 is slidably provided in the annular plate 61. One end of the slide plate 63 passes through the annular plate 61 and the limiting hole 62 and is fixed to the limiting plate 64. By placing the limiting plate 64 on one side of the plug plate 5, the plug plate 5 can be limited. A side rod 65 is fixed to the side wall of the slide plate 63. One end of the side rod 65 passes through the side wall of the annular plate 61 and is fixed to the connecting rod 64. Plate 67, the side rod 65 is covered with a spring 66, one end of the spring 66 is fixed to the side wall of the connecting plate 67, the side wall of the connecting plate 67 is provided with anti-slip grooves, and the other end of the spring 66 is fixed to the side wall of the annular plate 61. When the brush head 1 needs to be disassembled, it is only necessary to press the connecting plate 67. Pressing the connecting plate 67 can drive the slide plate 63 to move, and the movement of the slide plate 63 can drive the limit plate 64 to move, and then pull the support plate 2 outward to pull the limit plate 64 out along the limit hole 62.

[0025] The working principle and usage process of the present invention are as follows: by inserting one end of the support plate 2 of the brush head 1 into the groove 3, the inserting plate 5 can be limited by the limiting mechanism 6, so that the brush head 1 can be installed on the brush handle 7. When the brush head 1 needs to be replaced, it is only necessary to press the connecting plate 67 and then pull the support plate 2 outward to pull the limiting plate 64 out along the limiting hole 62, and then install the support plate 2 of a new brush head 1 on the brush handle 7.
