The main body mechanism 1 also includes a plastic snap ring 105, which is movably mounted on the outer end of the connecting rod 103, and the plastic snap ring 105 is located in front of the auxiliary telescopic inner rod 102. The main body mechanism 1 also includes a plastic locking protrusion 106, which is fixedly mounted on the inner end of the plastic snap ring 105, and the plastic locking protrusion 106 is movably connected with the snap-fit ​​groove 104. During the use of the telescopic rod body 101, the user puts the plastic snap ring 105 on the outer end of the connecting rod 103, and the user inserts the auxiliary telescopic inner rod 102 into the connecting cavity 203 inside the telescopic rod body 101. By pulling the auxiliary telescopic inner rod 102, the length of the auxiliary telescopic inner rod 102 extended is adjusted, and when it is adjusted to a suitable length After that, the user holds the auxiliary telescopic inner rod 102 and rotates it to the left, and the auxiliary telescopic inner rod 102 drives the connecting rod 103 to rotate, so that the plastic locking protrusion 106 on the plastic snap ring 105 is embedded in the engaging groove 104 on the connecting rod 103, thereby positioning the plastic snap ring 105. During the rotation process of the auxiliary telescopic inner rod 102, the plastic snap ring 105 is driven to rotate, so that the external threaded strip 202 on the plastic snap ring 105 is fully in contact with the inner wall of the telescopic rod body 101 for friction, thereby fixing the auxiliary telescopic inner rod 102 to the telescopic rod body 101, and the telescopic inner rod 102 can be used.
