[0026] Reference Figures 1-4 A deformable medical cleaning brush, comprising: a No. 1 brush head 2 and two No. 2 brush heads 3, the No. 1 brush head 2 is in square structure with rounded edges, and the No. 2 brush heads 3 are both in arc structure, and the No. 1 brush head 2 and the two No. 2 brush heads 3 can form a complete circular structure after splicing.

[0027] Specifically, as Figure 2As shown, brush bristles 8 are provided on the sides of the first brush head 2 and the two second brush heads 3. Therefore, after the first brush head 2 and the two second brush heads 3 are assembled, the curved surface of the instrument can be cleaned through the side of the deformed circular brush head (i.e., brush bristles 8).

[0028] Furthermore, brush bristles 9 are provided at the bottom of both brush head 2 and the two brush heads 3, which can be used for daily surface cleaning.

[0029] Furthermore, slots 11 are provided on both sides of the first brush head 2, and inserts 7 are integrally connected to one side of each of the two second brush heads 3, and the inserts 7 can be inserted into the slots 11.

[0030] like Figure 1 As shown, two positioning components are set above the first brush head 2.

[0031] Specifically, such as Figure 4 As shown, the positioning frame 4 in the positioning assembly is fixed above the first brush head 2. The upper part of the positioning frame 4 is rotatably connected to the handle 16. The inner side of the positioning frame 4 is rotatably connected to the lead screw 17. The lead screw 17 is fixed to one end of the handle 16, and a slider 19 is threadedly connected to the outside of the lead screw 17. The slider 19 is slidably installed on the inner side of the positioning frame 4.

[0032] Furthermore, two guide rods 18 are fixed inside the positioning frame 4, both of which pass through the slider 19, and a positioning rod 20 is connected to one side of the bottom of the slider 19.

[0033] At the same time, such as Figure 2 As shown, positioning holes 10 are provided on the surface of the insert block 7 and the surface of the first brush head 2.

[0034] In this embodiment, after all the inserts 7 are inserted into the slots 11, the handle 16 is rotated to drive the lead screw 17 to rotate, causing the external slider 19 to move downward, which in turn drives the positioning rod 20 to move downward. During the movement, the slider 19 slides outside the two guide rods 18 at the same time. The two guide rods 18 can improve the stability of linear displacement. After the positioning rod 20 passes through the positioning hole 2 10 on the surface of the first brush head 2, it enters the positioning hole 2 10 on the surface of the insert 7, thereby fixing the insert 7 in the slots 11 and completing the assembly of the second brush head 3 and the first brush head 2.
