[0024] Please refer to Figure 1-5 A telescopic support rod comprises a rod body 1 and a fixing sleeve 2 arranged at one end of the rod body 1, the rod body 1 is a telescopic rod, the rod body 1 comprises a first rod body 11, a second rod body 12, a fixing member 13 and a movable member 14, the second rod body 12 is partially located in the first rod body 11, the fixing member 13 is fixedly arranged on the first rod body 11, and the movable member 14 is arranged on the fixing member 13, an external thread is arranged on the outer wall of the fixing member 13, and an internal thread is arranged on the inner wall of the movable member 14, and the internal thread and the external thread are used in combination, that is, the movable member 14 can rotate and move on the fixing sleeve 2 by utilizing the characteristics of the thread, and a plurality of cracks 15 are arranged at one end of the fixing member 13, and the cracks 15 are evenly spaced on the fixing member 13, and the cracks 15 divide this end of the fixing member 13 into a plurality of clamping heads 16, and a first inclined surface 17 is arranged on the outer wall of the clamping head 16, and a second inclined surface 18 is arranged on the inner wall of the movable member 14, and the second inclined surface 18 is used in combination with the first inclined surface 17.

[0025] Specifically, due to the design of the split 15, when the second inclined surface 18 contacts the first inclined surface 17, the second inclined surface 18 will squeeze the first inclined surface 17, so that the clamping head 16 presses the second rod body 12 to lock the second rod body 12, so that the second rod member is fixed to the first rod member; when the second inclined surface 18 separates from the first inclined surface 17, the second inclined surface 18 will loosen the first inclined surface 17, so that the clamping head 16 loosens the second rod member, thereby unlocking the second rod member, so that the second rod member can move in the first rod member, that is, the length of the rod body 1 is adjustable. In other words, by rotating the movable part 14, the second inclined surface 18 is moved closer to (away from) the first inclined surface 17 to achieve the purpose of locking (unlocking) the second rod member, and the function of extending or shortening the rod body 1 can be realized, thereby achieving stable support for trees 3 of different heights, and has the characteristics of easy installation and firm support, so that the trees 3 can have sufficient and reliable support with the bottom soil, thereby improving the survival rate of the trees 3.

[0026] In this embodiment, the fixing sleeve 2 includes a connecting piece 21, a first semicircular sleeve 22, a second semicircular sleeve 23 and a screw 24. The connecting piece 21 is arranged on the second rod body 12; a connecting port 25 is arranged at the end of the first semicircular sleeve 22, and a connecting head 26 is arranged at the end of the second semicircular sleeve 23. The connecting head 26 is used in conjunction with the connecting port 25. A through hole 27 penetrating the first semicircular sleeve 22 is also arranged at the end of the first semicircular sleeve 22, and a threaded hole 28 penetrating the second semicircular sleeve 23 is also arranged at the end of the second semicircular sleeve 23; a clamping block 29 is arranged at the end of the screw 24.

[0027] Specifically, the connecting member 21, the first semicircular sleeve 22, and the second semicircular sleeve 23 are provided with connecting holes at corresponding positions. The first semicircular sleeve 22 and the second semicircular sleeve 23 are movably connected to the connecting member 21 through a connecting shaft. One end of the first semicircular sleeve 22 and the second semicircular sleeve 23 can rotate around the connecting member 21, and the other end of the first semicircular sleeve 22 and the second semicircular sleeve 23 are connected together through a connecting head 26, a connecting port 25 and a fastener.

[0028] In this embodiment, a lower rotating handle 19 is provided at the other end of the rod body 1. Specifically, the lower rotating handle 19 is fixedly connected to the first rod body 111. The lower rotating handle 19 is a conical structure that is wide at the top and narrow at the bottom. A spiral blade 110 is provided on the outer surface of the lower rotating handle 19. The spiral blade 110 is also a conical structure that is wide at the top and narrow at the bottom. The spiral blade 110 enables the lower rotating handle 19 to be inserted into the soil more labor-savingly and conveniently when rotating downward. After insertion, the spiral blade 110 is subjected to the squeezing force from the soil, so that the lower rotating handle 19 is not easily pulled out, and is convenient to fix.

[0029] In this embodiment, the first rod body 11 and the second rod body 12 are stainless steel hollow pipes. Compared with wooden support rods, stainless steel pipes are not easily corroded or damaged and can be reused.

[0030] The utility model is a telescopic support rod, and its working principle is described in conjunction with the accompanying drawings:

[0031] When in use, first rotate the movable part 14 to loosen the second rod body 12, adjust the length of the telescopic support rod according to the different heights of the trees 3, open the first semicircular sleeve 22 and the second semicircular sleeve 23, insert the telescopic support rod into the soil around the tree 3 through the lower rotating handle 19, adjust the first semicircular sleeve 22 and the second semicircular sleeve 23, insert the connecting head 26 into the connecting port 25, align the through hole 27 and the threaded hole 28, assemble the fasteners into the through hole 27 and the threaded hole 28, fix the first semicircular sleeve 22 and the second semicircular sleeve 23 together through the fasteners, and finally rotate the screw rod 24 to adjust the clamping block 29 so that the clamping block 29 fits tightly against the tree 3 to fix the tree 3.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
