Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1 to 7, in an embodiment of the present invention, a telescopic rotating shaft includes a sleeve shaft 1 and a telescopic shaft 2, a sliding hole 3 is formed in a lower end surface of the sleeve shaft 1, the telescopic shaft 2 is slidably installed in the sliding hole 3, a rotating groove 4 is separately formed in a middle portion of the sleeve shaft 1, the rotating groove 4 is communicated with the sliding hole 3, a threaded ring 5 is rotatably installed in the rotating groove 4, the threaded ring 5 is in threaded connection with the telescopic shaft 2, and the telescopic shaft 2 can be controlled to slide upwards or downwards in the sliding hole 3 by rotating the threaded ring 5.

In this embodiment, the cross section of the telescopic shaft 2 is similar to a waist circle, two arc edges are connected through two straight edges, and the cross section of the telescopic shaft 2 in the cross section of the sliding hole 3 is the same, so that the telescopic shaft 2 cannot rotate in the sliding hole 3, and the telescopic shaft 2 can be in threaded fit with the threaded ring 5.

In this embodiment, the front end face fixed mounting has first slider 6 in the slide opening 3, and first spout 7 has been seted up to the front end face of telescopic shaft 2, and first slider 6 and first spout 7 sliding fit can carry out spacingly to the slip of telescopic shaft 2 through first slider 6 and first spout 7 sliding fit.

In this embodiment, the outer end surface of the sleeve shaft 1 is provided with the second chute 8, the outer end surface of the sleeve shaft 1 is provided with the protective ring 9 in a sliding manner, the inner cavity of the protective ring 9 is fixedly provided with the second slider 10, the second slider 10 is in sliding fit with the second chute 8, and in the normal use process, the protective ring 9 can be sleeved on the outer side of the rotating groove 4, so that the threaded ring 5 cannot rotate in the use process.

In this embodiment, the outer surface of the thread ring 5 is fixedly provided with a friction protrusion, which is convenient for people to rotate the thread ring 5.

The working principle of the utility model is as follows:

when the length of the telescopic shaft 2 extending out of the sliding hole 3 needs to be adjusted, a user firstly needs to slide the protective ring 9 upwards to expose the rotating groove 4 on the surface of the sleeve shaft 1, at this time, the user can see the thread ring 5 in the rotating groove 4, then, the user holds the thread ring 5 with a hand and then rotates the thread ring 5, as the thread ring 5 is in threaded connection with the telescopic rod, when the thread ring 5 rotates, the telescopic shaft 2 can slide upwards or downwards in the sliding hole 3 according to the rotating direction of the thread ring 5, at this time, the user needs to slide the telescopic shaft 2 downwards in the sliding hole 3, the telescopic shaft 2 can slowly extend out of the sliding hole 3, so that the overall length of the sleeve shaft 1 and the telescopic shaft 2 can be increased, when the first sliding block 6 slides to the uppermost end of the first sliding groove 7, the telescopic shaft 2 extends out to the maximum distance, and when the telescopic shaft 2 is adjusted to the proper length, the user firstly releases the thread ring 5, then the protective ring 9 is released, the protective ring 9 falls down to block the thread ring 5.
