The telescopic rod is lengthened to the required length, and then the telescopic screw 27 is inserted into the inner hole 29 of the nearest telescopic screw, so that the telescopic rod can not be contracted and lengthened under the condition of stress, and the heavy object can be borne.

In a specific embodiment, the first supporting rod 1 is provided with a glass brush 20 for wiping glass, the glass brush 20 is provided with a water pipe fixing structure for fixing a water pipe 21, one end of the water pipe 21 is fixed on the glass brush, the other end of the water pipe is connected with a rubber ball 23, and the rubber ball 23 is connected with a one-way valve 24 and then is connected with a water inlet pipe. By squeezing the rubber ball 23, the space volume in the rubber ball 23 is reduced, water is squeezed into the water pipe 21, after the rubber ball 23 is restored to the normal state, the air pressure in the rubber ball 23 is reduced, external water enters the rubber ball 23 through the one-way valve 24 under the action of atmospheric pressure, the rubber ball 23 is squeezed again, the space volume in the rubber ball 23 is reduced, water is squeezed into the water pipe 21, and the steps are repeated, so that the cleaning fluid or clear water is sprayed on the glass, as shown in fig. 14. The rubber ball 23 can be placed in the armpit by foot or by hand. This configuration of the rubber bulb 23 is known in the art and is useful in a sphygmomanometer for a doctor, as is the case with the pressurized rubber bulb 23 pinched by the doctor's hand.

In a specific embodiment, the first supporting rod 1 is provided with a camera fixing structure for fixing the camera 22, one end of the camera 22 is aligned with the glass, and the other end of the camera 22 is connected with a notebook computer and other equipment, so that the place where the eyes can not see can be seen, and the glass in the place where the eyes can not see can be smeared completely. Therefore, the tool rod can be bent into different shapes through a plurality of rotating structures, and places which can not be reached by a common method can be reached, particularly the outer side of the window glass, and the outer side of the window glass is wiped clean. The tool bar can be used to carry a glass brush 20 to wipe the glass clean, which is a common half-open window, and can be extended from the upper openable window to the lower wiping glass in the case of a floor window.

In addition, in the household life, there are many places where long poles are needed for doing things, and some poles that need to be bent for doing things, such as a fork 19, as shown in fig. 13, which can be done by the poles.
