[0002] A mop is a cleaning tool commonly used in daily life. At present, the cleaning head of a mop usually comprises a cleaning cover for mopping the ground, a cleaning rod clamped in the cleaning cover, and a connecting end connected with the cleaning rod by a screw.

[0003] In the prior art, there is a cleaning head disclosed in application number 202120208809.9, in which the mop cleaning head includes a cleaning member, and the mop cleaning head also includes: a clamping member, the clamping member includes two clamping parts arranged opposite to each other; a connecting member, the connecting member includes a clamped part and a connecting part, the clamped part is located between the two clamping parts, and the connecting part is used to connect to the mop body; wherein, the two clamping parts jointly clamp the clamped part and the cleaning member. The clamping member corresponds to the cleaning rod. Since the cleaning rod has a fixed length, in actual application, if the length of the cleaning rod is long, it is easy to cause inconvenience in transportation and the cleaning head cannot be used in narrow areas. If the length of the cleaning rod is too short, the size of the cleaning cover of its outer jacket will be too short, which will result in a smaller area that can be cleaned and cannot be used in scenes where a large area is cleaned.

One end of the connecting rod 1 is provided with a connecting hole 3 for fixedly connecting to a mop rod, and the other end of the connecting rod 1 is fixedly connected to the middle position of the cleaning rod 2 through a first connecting end 23. The cleaning rod 2 comprises a middle fixed sleeve 4 and two telescopic sections 5 that are respectively movably sleeved on both ends of the fixed sleeve 4. Two stepped positioning and return structures corresponding to the telescopic sections 5 are provided in the cleaning rod 2. The stepped positioning and return structures are used to control the elastic pressing and extension of the fixed sleeve 4 and the telescopic section 5. When the telescopic section 5 is pressed in the fixed sleeve 4, the telescopic section 5 contracts in the fixed sleeve 4. When the telescopic section 5 is pressed in the fixed sleeve 4 again, the telescopic section 5 elastically extends, and the cleaning rod 2 is built into the provided cleaning sleeve.

[0027] The telescopic joint 5 is limited in sliding movement in the sliding chamber 6 provided in the fixed sleeve 4, and a pressure spring 7 is provided between the telescopic joint 5 and the sliding chamber 6. The two ends of the pressure spring 7 respectively abut against the bottom of the telescopic joint 5 and the bottom wall of the sliding chamber 6. The pressure spring 7 is used to generate an outward elastic force on the telescopic joint 5. A mounting groove 8 is provided at the bottom of the sliding chamber 6, and a limit adjustment rod 9 is movably installed in the mounting groove 8. One end of the limit adjustment rod 9 is movably hinged to the inner wall of the mounting groove 8, and the other end of the limit adjustment rod 9 is provided with a radially protruding roller 10; a square adjustment chamber 26 is provided in the telescopic joint 5, and an inner wall of the square adjustment chamber 26 is provided with a stepped positioning groove 11, and the stepped positioning groove 11 and the roller 10 constitute a guide rail.

[0028] like Figure 6 As shown, the stepped positioning slot 11 includes an inner position 13 close to the limit adjustment rod 9 and an outer position 12 away from the adjustment rod. Figure 7 As shown, when the roller 10 is in the inner gear position 13, the telescopic joint 5 is retracted into the sliding chamber 6. Figure 8 As shown, when the roller 10 slides to the outer gear position 12, the telescopic section 5 extends outward relative to the fixed sleeve 4. Figure 6-8As shown, the inner gear position 13 is composed of a first gear arc portion 14 and a first inner guide inclined wall 15, the first gear arc portion 14 and the roller 10 form a limiting fit, the first inner guide inclined wall 15 is inclined to one side relative to the first gear arc portion 14, and the first inner guide inclined wall 15 is used for the roller 10 to slide along a fixed side direction when it disengages from the first gear arc portion 14, and the outer gear position 12 is composed of a second gear arc portion 16 and a second inner guide inclined wall 17, the second inner guide inclined wall 17 is inclined to one side relative to the second gear arc portion 16, the first inner guide inclined wall 15 and the second inner guide inclined wall 17 are used to control the roller 10 to perform guide rail movement along the stepped locking groove 11 in a fixed direction of either clockwise or counterclockwise, and the first gear arc portion 14 and the second gear arc portion 16 are used to control the gear position of the roller 10 to be fixed.

[0029] like Figure 9 As shown, the bottom of the telescopic joint 5 is provided with a radially protruding positioning flange 18, and the positioning flange 18 forms a limiting fit with the annular limiting portion 19 provided on the outer side of the fixing sleeve 4. Figure 2 As shown, each of the telescopic sections 5 is provided with two axial track grooves 20 extending along the length direction of the telescopic section 5. The axial track grooves 20 cooperate with the track protrusions provided in the fixed sleeve 4 to form an axial guide rail. The axial track grooves 20 are used to prevent the telescopic section 5 from rotating circumferentially relative to the fixed sleeve 4.

[0030] like Figure 1-3 As shown, a glass scraper assembly 22 is fixedly mounted on the other side of the connecting rod 1. The glass scraper assembly 22 includes a second connecting end 24 connected to the end of the connecting rod 1 and a glass scraper 25 mounted on the end of the second connecting end 24. The first connecting end 23 and the second connecting end 24 are connected to the same end of the connecting rod 1 in a branch-like manner. A mounting bevel 21 is provided on one side of the second connecting end 24. The mounting bevel 21 fits the glass scraper 25. The mounting bevel 21 and the glass scraper 25 are fixedly mounted via a threaded connection assembly. Compared to a general telescopic structure, the stepped locking return structure described in this application has the function of contracting and popping out by repeated pressing. Moreover, the length after popping out is fixed and has good stability. In actual applications, it has a better stability effect and is highly practical.

[0031] Operating principle: as in this embodiment Figure 6-8 As shown, when the telescopic joint 5 is not initially pressed, the roller 10 is located at Figure 7 In the inner gear position 13 shown, since the end of the first inner guide inclined surface wall 15 is offset to one side relative to the first outer first gear arc portion 14, when the telescopic joint 5 is pressed again, the roller 10 moves along the first inner guide inclined surface wall 15 to the inner gear position 13. Figure 7When the roller 10 slides along the stepped locking groove 11 from the inner gear position 13 to the outer gear position 12, the telescopic rod is released, and the roller 10 is now incorporated into the second gear arc portion 16. When pressed again, the second inner guide inclined wall 17 is tilted to one side relative to the second gear arc portion 16, thereby achieving directional gear adjustment of the roller 10.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to provide an exhaustive list of implementation methods. However, any obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
