[0024] In this embodiment, the rotating seat 201 is arranged in the middle of the connecting rod 105, which facilitates the folding of the connecting rod 105 and the carrying of the device, reduces the space occupied by the device during storage and transportation, facilitates storage and management, and improves the convenience of the device. By installing the support block 202 in the middle of the connecting rod 105, it is beneficial to provide support for the connecting rod 105 and ensure the stability of the connecting rod 105. At the same time, the limiting pin 204 is passed through the interior of the limiting hole 203, which is beneficial to limiting. The tension of the tension spring 206 is used to fix the limiting pin 204 with the fixing bolt 205, thereby ensuring the stability and reliability of the limiting pin 204 in limiting the position. The connecting plate 207 facilitates the installation of the tension spring 206.

[0025] Example 2

[0026] like Figure 1-Figure 4 As shown, the cleaning assembly 3 includes a mounting plate 301, the side of the mounting plate 301 is connected to the side of the connecting rod 105, a spring 302 is installed at the bottom of the mounting plate 301, the bottom of the spring 302 is connected to a cleaning plate 303, a scraper 304 and a cleaning brush 305 are installed at the bottom of the cleaning plate 303, the scraper 304 and the cleaning brush 305 are arranged above the measuring wheel 101, a rotating shaft 102 is installed inside the measuring wheel 101, a counter 103 is installed on the outside of one end of the rotating shaft 102, a display screen 104 is installed on the top of the counter 103, a hand grip 106 is installed on the top of the connecting rod 105, rotating shafts 108 are installed on both sides of the connecting rod 105, and support plates 107 are installed on the sides of the rotating shaft 108.
