MOVABLE MULTI-DIRECTIONAL LIGHT STAND BACKGROUND OF THE INVENTION 5 1. Fields of the invention The present invention relates to a movable multi-directional light stand, especially to an adjustable and retractable light stand that can rotate in a horizontal plane so as to light in different directions. 2. Descriptions of Related Art 10 Generally, while camping or working outdoors at night, an illumination device is used for lighting. Thus there is a plurality of outdoor illumination device with different designs available now. For example, a fixed floor light is one of them. Such light is inconvenient because it is unable to adjust the height of the light. Thus insufficient 15 light is available or users need to- adjust surrounding elements in use. This is extremely inconvenient and annoying for users. In order to overcome above shortcomings, a foldable light stand is provided. The light stand is composed of a support base, a top support 20 rod, a hollow middle support rod and a light rod disposed on the top support rod. The support base includes three support feet, a connection seat, a central support rod and a movable fastening sleeve. The three support feet are pivoted to the connection seat and the central support 2 rod is assembled with a central hole of the connection seat. The hollow middle support rod is inserted into the central support rod. The central support rod and the middle support rod are assembled and disassembled with each other by a fastening nut. The top support rod is connected with 5 the middle support rod and is able to be received in the middle support rod. The light rod is connected with the top support rod. The disadvantage of above design is in that the light rod is unable to rotate an angle in a plane vertically so that the height of the light is unable to be adjusted. Moreover, the light rod is unable to fold and this is 10 inconvenient for storage. Thus there is a need to provide a light stand without disadvantages mentioned above while with better lighting effect and higher practice value. 15 SUMMARY OF THE INVENTION Therefore it is a primary object of the present invention to provide a movable multi-directional light stand that is adjustable and retractable. 20 At the same time, the light stand can rotate in a horizontal plane so as to light various areas from different directions. In order to achieve above object, the movable multi-directional light 3 stand includes a retractable top support rod that can be received into and connected with a hollow middle support rod. A mounting slot is disposed on a wall of the top support rod, along an axial direction of the support rod. A sleeve with external threads is disposed around the top of the top 5 support rod and is having a guiding slot corresponding to the mounting slot of the top support rod. A retractable light rod is pivoted to the wall of the top support rod that is disposed with the mounting slot. The retractable light rod consists of a hollow outer tube and an inner tube. The inner tube is having a hook and sliding in the outer tube. An 10 adjustment nut has threads engaging corresponding external threads of the sleeve so as to support the outer tube, locate the retractable light rod in the mounting slot and adjust the height of the light. The movable multi-directional light stand of the present invention 15 further includes a top head nut with internal threads and a stud on the top of the top head nut. Thus the top head nut is disassembled or assembled with the sleeve by the internal threads engaging with the external threads. The stud matches a screw hole on one end of the top support rod. 20 The movable multi-directional light stand of the present invention is further disposed with a connection seat that has an axial through hole and external threads for fastening on the upper part thereof. The top end of the middle support inserts into the through hole and the bottom end of 4 the top support rod inserts into the middle support rod. By the fastening nut engaging the external threads for fastening, the middle support rod is connected with and fixed on the connection seat. 5 In the movable multi-directional light stand of the present invention, a locating hole is disposed on one end of the outer tube of the retractable light rod while the other end thereof is arranged with a locating pin. The inner tube is disposed with a sliding slot for the locating pin of the outer tube to slide therein while a locating pin is arranged at one end of the 10 inner tube that is mounted into the outer tube correspondingly. Thereby, the extension length of the retractable light rod can be adjusted. Moreover, both the outer tube and the inner tube of the movable multi-directional light stand can be designed into a cone-shaped post so 15 that the inner tube presses and leans against the outer tube tightly by the cone angle while being pulled out.

The support feet (11) are pivoted to the pivot seat (12) and the central support 10 rod (13) is assembled with and located onto the pivot seat (12) while the fastening nut (14) is disposed around the central support rod (13). The middle support rod (2) is correspondingly mounted into the central support rod (13). By the fastening nut (14), the middle support rod (2) and the central support rod (13) are assembled and disassembled with 15 each other.. The top support rod (3) is a rod that can be retracted into or extended from the middle support rod (2) and is disposed with a mounting slot (31) on a wall thereof, along an axial direction. The retractable light rod (4) consists of a hollow outer tube (41) and an inner tube (42). The inner tube (42) is having a hook (421) and is sliding inside 20 the outer tube (41). One end of the outer tube (41) is in the mounting slot (31), pivoted to the wall of the top support rod (3). A connection seat (5) with an axial through hole is disposed around the middle support rod (2). The upper part of the connection seat (5) is arranged with external 7 threads for fastening. The fastening nut (6) engages the external threads for fastening on the upper part of the connection seat (5) correspondingly. The sleeve (7) is a tube arranged with external threads so as to be disposed around the top of the top support rod (3). A guiding slot (71) 5 corresponding to the mounting slot (31) of the top support rod (3) is arranged at the sleeve (7). The adjustment nut (8) is with threads adapted to engage the external threads of the sleeve (7) so as to support the retractable light rod (4) and locate the retractable light rod (4) in the mounting slot (31). The top head nut (9) is disposed with internal threads 10 corresponding to the external threads of the sleeve (7) for disassembling or securing with each other. A stud (91) that matches one end of the top support rod (3) is arranged on the top of the top head nut (9). From Fig. 1 to Fig. 7, while adjusting the angle between the 15 retractable light rod (4) and the horizontal plane, the retractable light rod (4) is rotated counterclockwise. The adjustment nut (8) is also rotated to move forward for supporting the outer tube (41) of the retractable light rod (4). Thus one end of the retractable light rod (4) is moved upward and the light hanging on the end thereof is moving away from the ground. 20 When the retractable light rod (4) is rotated clockwise and the adjustment nut (8) is also rotated, the adjustment nut (8) is also rotated to move downward for supporting the outer tube (41) of the retractable light rod (4). And the end of the retractable light rod (4) is moving 8 toward the ground. The height of the light hanging on the end of the retractable light rod (4) is reduced, more close to the ground.
