DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

(10) First, please refer to FIG. 1 to FIG. 6. The tripod comprises: an outer tube 10, an intermediate tube 20, an inner tube 30, two positioning members 40, a connecting joint 50, a knob 60, a clamping device 70 and a leg set 80. The outer tube 10, the intermediate tube 20 and the inner tube 30 are sequentially sleeved on each other so that the intermediate tube 20 can perform coaxial telescopic movement along the inner tube of the outer tube 10 inside the outer tube 10. And the inner tube 30 can expand and contract coaxially along the intermediate tube 20. Furthermore, the outer tube 10 and the intermediate tube 20 are combined with a positioning member 40, and the intermediate tube 20 and the inner tube 30 are also combined with a positioning member 40. By controlling the positioning member 40 loosened or locked, the intermediate tube 20 or the inner tube 30 can be fixed after the telescopic movement. Moreover, the inner tube 30 is provided with a first engaging disk 31 and the first engaging disk 31 has a through aperture 311 at the center. A locking rod 51 extends above the connecting joint 50 and a second engaging disk 52 is disposed at one side of the connecting joint 50 and provided with a bolt 53. The bolt 53 penetrates the through aperture 311 and then protrudes from the other side of the first engaging disk 31 so that the connecting joint 50 can be pivoted on the first engaging disk 31 of the inner tube 30 by the insertion of the bolt 53. The knob 60 has a threaded aperture 61 configured for engaging with the bolt 53 on the other side of the first engaging disk 31 such that the connecting joint 50 can be adjusted to a predetermined angle on the first engaging disk 31. Then, the second engaging disk 52 and the knob 60 together clamp and position the connecting joint 50 on the first engaging disk 31. The clamping device 70 has a back member 71, a side member 72 and a slidable member 73. A first locking aperture 711 and a second locking aperture 721 are respectively disposed on the side member 72 and the back member 71, and one of locking apertures is utilizes for engaging with the locking rod 51 of the connecting joint 50 to lock the clamping device 70. Therefore, the image capture device 90 is able to be mounted in different directions. The leg set 80 is mounted below the outer tube 10 and has a plurality of supporting legs 81. Each supporting leg 81 has a first surface 811 and a second surface 812, and the second surface 812 further has a recess 813. As shown in FIG. 8, each recess 813 is also provided with a pivoted grounding nail 82 which can be turned out or folded inwards.

(11) In addition, the positioning member 40 is a tightening sleeve, and the threaded aperture 61 of the knob 60 is provided by a mounted nut. The knob 60 is provided with a stopping member 62, the bolt 53 is provided with a stopping edge 531, and the stopping member 62 jackets onto the bolt 53 and makes contact with the stopping edge 531 to prevent the knob 60 from falling off from the bolt 53. The stopping member 62 is a hollow sleeve with an inner stopping edge 621 and an opening 622. When the stopping member 62 enters is pushed into the knob 60, the opening 622 allows the inner stopping edge 621 to pass the stopping edge 531, which achieves the combination of the stopping member 62 and the bolt 53.

(12) For actual operation, first adjusting the length and swing angle of the tripod, then placing the image capture device 90 in the clamping device 70, and opening the supporting legs 81 to set up the tripod on the ground. The tripod lifts up the image capture device 90 which is suitable for recording and shooting the growth of plants, as shown in FIG. 7. In addition, the use of the grounding nail 82, as shown in FIG. 8, supports the tripod to be more stable. Furthermore, the intermediate tube 20, the inner tube 30 are able to retract and the supporting leg 81, the grounding nail 82 are able to fold back, shown in FIG. 9, to reduce its size, so that the tripod carrying or storing more convenient.

(13) With the structure of the above specific embodiment, the following benefits can be obtained: The tripod structure is a tripod dedicated to the image capture device 90 especially for long time period image recording such as plant growth. The height and swing angle of the tripod are adjustable, so the tripod in actual use can be more handy. Last, the intermediate tube 20, the inner tube 30 sequentially retracted back and the supporting leg 81, the grounding nail 82 can be folded up to reduce its size, so that the tripod can be carried or stored more convenient and space-free.

(14) Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
