[0028] like Figure 2 , Figure 4 As shown, the fixing mechanism 2 includes a button 21, the outer side of the button 21 is movably sleeved on the inner wall of the left side of the handle 1, an L-shaped rod 24 is fixedly connected to the axis of the lower surface of the button 21, the left end of the L-shaped rod 24 is slidably connected to a connecting rod 25, the middle part of the front and rear sides of the connecting rod 25 is rotatably connected to the position of the inner cavity on the right side of the handle 1 close to the left side, the left side of the connecting rod 25 is slidably connected to a fixed block 26, and the outer side of the fixed block 26 is movably sleeved on the lower side of the connecting head 3.

[0029] It should be noted that the connecting rod 25 is rotated in the middle, so that when the connecting rod 25 rotates, the two sides move in opposite directions. Pressing the button 21 causes the connecting rod 25 to rotate, and the rotation of the connecting rod 25 drives the fixing block 26 to move upward.

[0030] like Figure 2 , Figure 4 As shown, four annularly distributed hollow rods 22 are fixedly connected to the lower surface of the button 21 near the edge, the inner sides of the four hollow rods 22 are movably sleeved with first limit rods 23, the lower ends of the first limit rods 23 are fixedly connected to the lower surface of the inner cavity on the right side of the handle 1, the outer walls of the four hollow rods 22 are fixedly connected with circular plates near the bottom, the outer walls of the four first limit rods 23 are movably sleeved with first springs 27, and the first springs 27 are located on the lower side of the circular plate.

[0031] It should be noted that when the button 21 moves downward, it pushes the circular plate on the hollow rod 22, causing the first spring 27 to be compressed. When the button 21 is released, the first spring 27 pushes the hollow rod 22, causing the button 21 to reset.

[0032] like Figure 2 , Figure 4 As shown, the second limiting rod 28 is movably sleeved on the front and rear sides of the upper side of the fixing block 26 , and the upper and lower ends of the second limiting rod 28 are fixedly connected to the upper and lower sides of the inner wall of the connector 3 .

[0033] It should be noted that the second limiting rod 28 is used to limit the fixing block 26 so that the fixing block 26 can only move up and down, thereby preventing the moving route of the fixing block 26 from deviating.

[0034] like Figure 4 As shown, the outer walls of the two second limiting rods 28 are movably sleeved with second springs 29 , and the second springs 29 are located on the upper side of the fixing block 26 .

[0035] It should be noted that the second spring 29 pushes the fixing block 26 downward, so that the fixing block 26 is close to the bottom of the connector 3, thereby preventing the fixing block 26 from shaking.

[0036] like Figure 3 , Figure 5 As shown, the connecting mechanism 4 includes a connecting sleeve 41, the right side of the replacement tool head 5 is fixedly connected to the left side of the connecting sleeve 41, the outer wall of the connecting sleeve 41 is movably sleeved on the outside of the connecting head 3, the outer side of the fixing block 26 near the lower side is movably sleeved in the socket opened at the lower side of the connecting sleeve 41 near the right side, and the fixing block 26 is in the shape of a right-angled trapezoid, and the inclined surface of the fixing block 26 faces the lower left side.

[0037] It should be noted that when the fixing block 26 is movably sleeved into the inner side of the socket, the connecting sleeve 41 is fixed to the outer side of the connector 3. The shape of the fixing block 26 causes the connecting sleeve 41 to be movably sleeved to the outer side of the connector 3 from the left side. The right side of the connecting sleeve 41 can push the fixing block 26 upward until the socket is aligned with the fixing block 26. The second spring 29 pushes the fixing block 26 to return to its original position. The installation of the connecting sleeve 41 can be completed without pressing the button 21.

[0038] like Figure 5 As shown, a plurality of evenly distributed rubber strips 42 are embedded in the inner wall of the connecting sleeve 41 near the right side.

[0039] It should be noted that the rubber strip 42 is used to fill the gap between the connecting sleeve 41 and the connecting head 3 to prevent the connecting head 3 from shaking inside the connecting sleeve 41 .

[0040] like Figure 3 , Figure 5 As shown, four annularly distributed clamping strips 44 are movably sleeved on the inner wall of the connecting sleeve 41 near the left side, and the four clamping strips 44 are fixedly connected to the sides away from each other with spring sheets 43, and the spring sheets 43 are located near the left side of the inner cavity of the side wall of the connecting sleeve 41, and four annularly distributed clamping grooves 45 are opened on the outer wall of the left side convex column of the connecting head 3, and the outer side of the clamping strip 44 is movably sleeved on the inner side of the clamping groove 45, and the right side of the clamping strip 44 is wedge-shaped.

[0041] It should be noted that the spring sheet 43 pushes the clamping strip 44, causing the clamping strip 44 to clamp the connector 3, thereby preventing the connector 3 from being worn out due to repeated plugging and unplugging, increasing the gap between the connecting sleeve 41 and the connector 3, causing the connector 3 to shake on the inside of the connecting sleeve 41, and the clamping groove 45 is used to fix the connector 3, causing the clamping strip 44 to be stuck on the inside of the clamping groove 45, thereby preventing the connector 3 from rotating on the inside of the connecting sleeve 41 due to excessive wear of the lower side socket of the connecting sleeve 41. The shape of the clamping strip 44 is convenient for the clamping strip 44 to easily slide into the inside of the clamping groove 45 when installing the connecting sleeve 41.

[0042] The working principle of the utility model is as follows: first, the rotation position of the connecting rod 25 is located in the middle, so that when the connecting rod 25 rotates, the moving directions of the two sides are opposite, and the button 21 is pressed to cause the connecting rod 25 to rotate, and the rotation of the connecting rod 25 drives the fixed block 26 to move up. When the button 21 moves down, it pushes the circular plate on the hollow rod 22, causing the first spring 27 to be compressed. When the button 21 is released, the first spring 27 pushes the hollow rod 22, causing the button 21 to reset. The second limit rod 28 is used to limit the fixed block 26, so that the fixed block 26 can only move up and down to prevent the moving route of the fixed block 26 from deviating. The second spring 29 pushes the fixed block 26 downward, causing the fixed block 26 to be close to the bottom of the connector 3. The fixing block 26 is prevented from shaking. When the fixing block 26 is movably sleeved into the inner side of the socket, the connecting sleeve 41 is fixed to the outer side of the connecting head 3. The shape of the fixing block 26 causes the connecting sleeve 41 to be movably sleeved on the outer side of the connecting head 3 from the left side. The right side of the connecting sleeve 41 can push the fixing block 26 to move up until the socket is aligned with the fixing block 26. The second spring 29 pushes the fixing block 26 to reset. The installation of the connecting sleeve 41 can be completed without pressing the button 21. The fixing between the handle 1 and the replacement tool head 5 is completed by movably sleeved the connecting sleeve 41 on the outer side of the connecting head 3. The button 21 is pressed to disengage the fixing block 26 from the socket on the lower side of the connecting sleeve 41, completing the connection between the handle 1 and the replacement tool The separation between the heads 5 achieves the purpose of quickly installing and disassembling the handle 1 and the replacement tool head 5. By installing the connecting sleeve 41 of the same specification on the tool heads 5 with different functions, the purpose of quickly replacing the function of the tool brush is achieved. A single handle 1 corresponds to multiple replacement tool heads 5, realizing the replacement of different functions and improving the adaptability of the tool brush. Finally, the rubber strip 42 is used to fill the gap between the connecting sleeve 41 and the connecting head 3 to prevent the connecting head 3 from shaking inside the connecting sleeve 41. The spring sheet 43 pushes the clamping strip 44, causing the clamping strip 44 to clamp the connecting head 3 to prevent the connecting head 3 from being worn due to repeated plugging and unplugging, thereby increasing the gap between the connecting sleeve 41 and the connecting head 3. The connector 3 is made to shake on the inner side of the connecting sleeve 41. The card slot 45 is used to fix the connector 3, so that the card strip 44 is stuck on the inner side of the card slot 45, to prevent the connector 3 from rotating on the inner side of the connecting sleeve 41 due to excessive wear of the lower side socket of the connecting sleeve 41. The shape of the card strip 44 is convenient for installing the connecting sleeve 41. The card strip 44 can easily slide into the inner side of the card slot 45, and the gap between the connecting sleeve 41 and the connector 3 is filled by the rubber strip 42. The spring sheet 43 pushes the card strip 44 to clamp the left side boss of the connector 3, so that the connector 3 is fixed on the inner side of the connecting sleeve 41, to avoid frequent plugging and unplugging of the connector 3, causing it to wear, causing the connector 3 to shake in the connecting sleeve 41, affecting the use of the tool brush.
