[0050] Furthermore, in this embodiment, a circular ring 25 is provided at the geometric center position of the end of each rotating module 221, and the end of the wire rope 24 away from the return spring 23 passes through the circular ring 25 and is connected to the slider 224; by providing the circular ring 25, the wire rope 24 is always in the center line position.

[0051] Furthermore, in this embodiment, the rotating module 221 includes a ring 2212 and a rotating shaft 2213. A rotating groove 2214 is opened on the outer peripheral wall of the rotating shaft 2213. The rotating groove 2214 is adapted to the ring 2212. The ring 2212 is sleeved on the rotating shaft 2213. The ring 2212 is located in the rotating groove 2214. The ring 2212 and the rotating shaft 2213 can rotate relative to each other; the ends of the two adjacent connecting rods 21 are respectively connected to the outer peripheral walls of the ring 2212 and the rotating shaft 2213.

[0052] Specifically, the end of one connecting rod 21 is connected to the outer peripheral wall of the ring 2212, and the end of the other connecting rod 21 is connected to the outer peripheral wall of the rotating shaft 2213. The center line of the ring 2212 and the center line of the rotating shaft 2213 are both set parallel to the Y direction, and the center line of the ring 2212 and the center line of the rotating shaft 2213 are both set perpendicular to the center line of the connecting rod 21.

A second positioning hole is opened in the rotating groove 2214, and the second positioning hole extends radially inwardly along the rotating shaft 2213. The first positioning hole and the second positioning hole are arranged correspondingly, and the first positioning hole and the second positioning hole are connected to form a pin hole 2211.

[0055] Continue to refer to Figure 1 In this embodiment, a rectangular frame 212 is provided at the end of the connecting rod 21 located at the second end of the rod body assembly 20, and a handle 213 is provided in the rectangular frame 212. The two ends of the handle 213 are slidably connected to the two opposite inner walls of the rectangular frame 212 respectively, and the handle 213 can slide relative to the rectangular frame 212. The end of the wire rope 24 away from the reset spring 23 passes through the rectangular frame 212 and is connected to the handle 213.

[0056] Specifically, Figure 1 Taking the shown position as an example, a rectangular frame 212 is provided at the right end of the rightmost connecting rod 21, and slide rails are provided on the two opposite inner walls of the rectangular frame 212. The opposite ends of the handle 213 are respectively inserted into the two slide rails, and the handle 213 can slide along the slide rails.

[0057] The use process of the adjustable connecting rod brush 1 provided in this embodiment is: the bracket spring 11 is stretched or squeezed by two adjustment plates 12 at the same time to adjust the distance between the upper and lower brush heads 131.

[0058] When the handle 213 is pulled, the return spring 23 is stretched, and the wire rope 24 drives the slider 224 to move rightward. The slider 224 drives the latch 222 to slide through the coil spring 223. When the latch 222 slides out of the pin hole 2211, the two adjacent connecting rods 21 can rotate relative to each other.

[0059] When the handle 213 is released, the return spring 23 pulls back the wire rope 24, and the wire rope 24 drives the slider 224 to return to its original position. The pin 222 of the two adjacent connecting rods 21 that remain in a straight state will return to the pin hole 2211, ensuring that the connecting rods 21 on both sides of the rotating module 221 here maintain rigidity; and the pin 222 with a preset angle sandwiched between the two adjacent connecting rods 21 will be stuck on the outside of the pin hole 2211, and the spiral spring 223 will be compressed, so as not to affect the smooth pulling back of the wire rope 24 and the return of the pin 222 in other parts to the pin hole 2211. The pin 222 is stuck in the rotating unit 22 outside the pin hole 2211, and the rotating module 221 here can rotate smoothly. Under the constraint of the ring 25, the wire rope 24 will always be at the center line position of the connecting rod 21.
