Fixed connection, one side of the main shaft 4 is fixedly connected with a positioning switch 6, one side of the sliding sleeve 5 is provided with a positioning hole 7, the positioning switch 6 is movably connected with the positioning hole 7, and the surface of the main shaft 4 is sleeved with a position above the sliding sleeve 5. The inner wall of the extension tube 8 is fixedly connected with the limit ring 9, the main shaft 4 is movably connected with the limit ring 9, the surface of the main shaft 4 is fixedly connected with a spacer ring 10 located under the limit ring 9, the surface of the main shaft 4 is sleeved A compression spring 11 is connected between the limit ring 9 and the spacer ring 10. One end of the main shaft 4 is provided with an installation groove 12 located above the limit ring 9. The inner wall of the installation groove 12 is fixedly connected with a first spring 13. One side of the spring 13 is fixedly connected with a clamping post 14 , one side of the elongated cylinder 8 is provided with a socket 15 , the clamping post 14 is inserted into the socket 15 , and the inner wall of the socket 15 is provided with a start switch 16 .

In this embodiment, by setting the ductile steel wire 3 with hair, when cleaning the inner wall of the flask, the steel wire 3 with ductility with hair is extended into the flask, and then the positioning switch 6 is pressed, and the steel wire with ductility with hair 3 will pull the sliding sleeve 5 down. , at this time, the ductile steel wire 3 with hair is in the unfolded state, so that it can be fully contacted with the inner wall of the flask. At this time, only the inner wall of the flask can be cleaned by rotating the elongated cylinder 8, and the cleaning effect is good, and the bottle mouth needs to be relatively clean. When cleaning the narrow part, it is only necessary to pull the sliding sleeve 5 upward, so that the ductile steel wire 3 with hair is in a shrinking state. Because the volume of the brush head is fixed, when cleaning flasks of different sizes, it will cause the problem of incomplete cleaning. When cleaning flasks with a deeper depth, just press the start switch 16, and the clamping column 14 is disengaged at this time. The socket 15, under the elastic force of the compression spring 11, pushes the main shaft 4 to move downward through the spacer ring 10, so that the main shaft 4 protrudes from the inside of the extension cylinder 8, so that the overall length of the brush can be increased, so that it can be deeper At the same time, when the extension cylinder 8 is pressed, the compression spring 11 can provide a buffer to prevent excessive pressure on the bottom of the flask by the ductile steel wire 3, and avoid the damage of the flask. When cleaning flasks with a high height, it is necessary to replace the brushes of different lengths, which is inconvenient for the staff to use. When the cleaning is completed, after cleaning the brushes, the sliding sleeve 5 can be pulled to make the positioning switch 6 stuck in the positioning hole 7 In this way, the ductile steel wire 3 with hair can be contracted, and at the same time, the extension cylinder 8 can be pressed, so that the clamping post 14 is stuck inside the insertion hole 15, so that the overall length of the brush can be shortened, so as to reduce the space occupied by it, and it is very convenient to carry. .

Example 2

Please refer to Figures 1-4, and further improvements have been made on the basis of Embodiment 1: the radius of the lower end face of the positioning post 2 is smaller than the radius of the upper end face, which facilitates the installation of the ductile steel wire 3 with hair so that it is located on the inner wall of the fixing sleeve 1 , the positioning switch 6 includes a positioning seat 61, the inner wall of the positioning seat 61 is provided with a positioning spring 62, and one side of the positioning spring 62 is fixedly connected with a pressing column 63. When unfolding the ductile steel wire 3 with hair, just press the pressing column 63 , the pressing post 63 can be separated from the positioning hole 7 . When shrinking, only the sliding sleeve 5 needs to be pulled, and the pressing post 63 can be stuck on the inner wall of the positioning hole 7 under the push of the positioning spring 62 .

The main shaft 4 is a T-shaped shaft, the diameter of the upper end face of the main shaft 4 is larger than the radius of the lower end face, and the installation groove 12 is located on the upper end side of the main shaft 4. Setting the main shaft 4 into a T-shaped shaft can make the main shaft 4 extend from the inside of the extension cylinder 8. When it comes out, it can be blocked by the limit ring 9 to prevent its extended position from being too long, resulting in the phenomenon that the reset is not smooth.

Example 3

Please refer to FIG. 1, 2, 3, 5 or 6, and further improvements are made on the basis of Embodiment 1: the start switch 16 includes a second spring 161 and a start column 162, and the second spring 161 is socketed with the start column 162, And the surface of the starting column 162 is sleeved with a spacer 163. When adjusting the length, you only need to press the starting column 162, and the starting column 162 pushes the clamping column 14 out of the insertion hole 15. The function of adjusting the length, when shrinking, is pushed by the first spring 13, the clamping post 14 is clamped inside the socket 15, and at the same time, under the pushing of the second spring 161, it can prevent the activation post 162 and the clamping post 14 Contacts.

The surface of the extension cylinder 8 is sleeved with a rubber sleeve 17, and the surface of the rubber sleeve 17 is provided with a resistance increasing thread.
