Thus, a feature defining "a first", "a second", etc. may explicitly or implicitly include one or more such feature. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art in a specific case.

The invention will be described in detail below with reference to the drawings in connection with embodiments.

Referring to fig. 1-7, in the embodiment of the invention, a rotatable telescopic rod comprises an upper outer pipe 3 and a lower outer pipe 5, a handshake sleeve is sleeved outside the upper outer pipe 3, a spanner lock 4 is arranged outside the joint of the upper outer pipe 3 and the lower outer pipe 5, the spanner lock 4 is used for locking the upper outer pipe 3 and the lower outer pipe 5 after being telescopic to a proper size to avoid the influence of the back-and-forth shrinkage of the upper outer pipe 3 and the lower outer pipe 5, an upper inner pipe 7 is arranged inside the upper outer pipe 3, the upper end of the upper inner pipe 7 is connected with a handle 1, an upper fixing sleeve 11 is connected between the lower end of the handle 1 and the upper outer pipe 3, a limit sleeve 8 is connected between the lower end of the upper outer pipe 3 and the upper end of the lower outer pipe 5, a lower inner pipe 6 is arranged inside the limit sleeve 8, the lower end of the lower outer pipe 5 is connected with a lower fixing sleeve 9, the lower fixing sleeve 9 is composed of an A sleeve at the upper end part and a B sleeve at the lower end part, the middle part of the lower fixing sleeve 9 is provided with a butterfly-shaped clamp spring 10, the outer side of the lower end of the lower section inner core tube 6 is provided with a key slot 11 matched with the butterfly-shaped clamp spring 10, when the lower section inner core tube is installed, the first dish-shaped clamp spring 10 is installed in the key slot 11 at the upper end, the A sleeve is sleeved, the second key slot 11 is sleeved with the second clamp spring, then the B sleeve is sleeved, the lower section inner core tube 6 is inserted into the lower section outer tube 5, the lower end of the B sleeve is provided with a step clamped at the edge of the lower section outer tube 5, the lower section outer tube 5 is matched with the lower fixing sleeve 9, the lower section inner core tube 6 can rotate in the lower section outer tube 5 but cannot slide out, in order to ensure that the lower section inner core tube 6 and a product are normally used, the lower section inner core tube 6 exceeds a part of the lower section outer tube 5, the upper section inner core pipe 7 and the lower section inner core pipe 6 are special pipes.

The working principle of the invention is as follows: the upper section inner core pipe 7 in this device is controlled by the handle 1 of telescopic link, whole telescopic link comprises 4 pipes, but two bore different upper section outer tube 3 and lower section outer tube 5 and two different insertable complex upper section inner core pipe 7 and lower section inner core pipe 6, the fixed cooperation is done with handle 1 to upper section inner core pipe 7 in this device, handle 1 end is equipped with the plug that mutually supports with upper section inner core pipe 7, then cooperate with it, later it is inserted in upper section outer tube 3 with handle 1 through last fixed cover 11 clamp, the fixed combination of upper fixed cover 11 and upper section outer tube 3 is realized, thereby make handle 1 drive upper section inner core pipe 7 rotate and can not slide in upper section outer tube 3, and then make the synchronous rotation of lower section inner core pipe 6 mutually supports with upper section inner core pipe 7, because upper section outer tube 3 inner wall is equipped with 3 protruding muscle positions, stop collar 8 outer wall is equipped with the muscle groove mutually supports with protruding muscle position, and then make stop collar 8 and upper section outer tube 3 can form a whole, so when lower section outer tube 5 is the same, can not rotate the outer tube 5 when can not slide in the upper section outer tube 5, the same time when the outer tube is rotated down, the outer tube is rotated, thereby can not rotate in the outer tube is realized.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
