Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings: Example

[0022] A portable, easy-to-deploy tool, such as Figure 1-5 As shown, it includes a support rod 1; a lower mounting rod 2 is provided at the lower end of the support rod 1, and the lower mounting rod 2 is connected to the lower end of the support rod 1 through a sliding adjustment block 4; an upper mounting rod 3 is provided at the upper end of the support rod 1, and the upper mounting rod 3 is connected to the upper end of the support rod 1 through a sliding adjustment block 4; support seats 5 are fixedly installed on both sides of the lower end of the lower mounting rod 2.

[0023] The support rod 1 includes a lower support rod 11 and an upper support rod 12. The upper end of the lower support rod 11 and one side of the lower end of the upper support rod 12 are fixedly hinged by a hinge member 13. A snap-fit ​​rod 14 and a snap-fit ​​shaft 15 are respectively fixedly provided at the lower end of the upper support rod 12 and the upper end of the lower support rod 11 away from the hinge member 13. The snap-fit ​​rod 14 and the snap-fit ​​shaft 15 are snapped together. The lower end of the lower support rod 11 and the upper end of the upper support rod 12 are also provided with sliding grooves 16. The bottom of the two sliding grooves 16 are respectively provided with clearance grooves that penetrate the upper support rod 12 and the lower support rod 11.

[0024] The lower mounting rod 2 includes a rod body 21 with a central cavity, and an opening at the upper end of the rod body 21 communicating with the cavity. A winding shaft 23 is rotatably mounted in the cavity of the rod body 21 via a bearing 22. A printing cloth 24 is wound on the winding shaft 23, and one end of the printing cloth 24 is fixedly connected to the winding shaft 23. A connecting rod 25 is provided at the upper end of the rod body 21, and the other end of the printing cloth 24 passes through the opening at the upper end of the rod body 21 and is fixedly connected to the connecting rod 25. Scroll springs 26, which are fixedly connected to the rod body 21, are also fixedly provided at both ends of the winding shaft 23.

[0025] The sliding adjustment block includes a slider 41 that is slidably disposed in the slide groove 16 provided in the upper mounting rod 3 and the lower mounting rod 2; a connecting plate 42 that is fixedly connected to the lower mounting rod 2 and the upper mounting rod 3 is provided on the side of the slider 41 away from the slide groove 16; a locking shaft 43 that protrudes from the end face of the connecting plate 42 near the slider 41, passes through the slider 41, passes through the clearance groove provided at the bottom of the slide groove 16, and extends to the other end of the support rod 1; a threaded shaft section is provided on the end of the locking shaft 43 away from the connecting plate 42, and a locking nut 44 is engaged with the threaded shaft section.

[0026] Working principle:

[0027] This utility model's easy-to-unfold unfolding tool unfolds by unfolding the lower support rod 11 and the upper support rod 12 along the hinge 13. Then, the lower support rod 11 and the upper support rod 12 are locked together by the locking rod 14 and the locking shaft 15. Next, the locking nut 44 is rotated to loosen it. After loosening, the upper mounting rod 3 and the lower mounting rod 2 are pushed towards both ends of the support rod 1. The lower mounting rod 2 and the upper mounting rod 3 move towards both ends along the sliding groove 16 under the action of the slider 41. Then, the lower mounting rod 2 and the upper mounting rod 3, which are fixedly mounted on the connecting plate 42, are rotated to make them perpendicular to the support rod 1. Finally, the locking nut 44 is rotated... 4. Pull the locking shaft 43, which drives the connecting plate 42 fixed thereto, causing the connecting plate 42 to clamp the slider 41; making the slider 41 unable to move and the connecting plate 42 unable to rotate, thereby locking and fixing the lower mounting rod 2 and the upper mounting rod 3; then place the lower mounting rod 2 on the ground through the support base 5, pull the connecting rod 25 upward, and the connecting rod 25 causes the inkjet cloth 24 rolled up in the cavity of the rod body 21 to extend out, and then connect the connecting hole on the connecting rod 25 to the connecting shaft 31 on the upper mounting rod 3, so that the connecting shaft 31 is inserted into the connecting hole to fix the connecting rod 25; then unfold the inkjet cloth 24 connected to the connecting rod 25 for display.

[0028] After the display is complete and it needs to be packed away, the connecting hole of the connecting rod 25 is separated from the connecting shaft 31 of the upper mounting rod 3. Then, the winding shaft 23 rotates under the action of the spiral spring 26 to wind up the inkjet cloth 24, so that the inkjet cloth 24 is wound into the cavity of the rod body 21. The inkjet cloth 24 drives the connecting rod 25 to move to the upper end of the rod body 21. Then, the operator rotates the locking nut 44 to loosen the locking nut 44 from the locking shaft 43. Then, the upper mounting rod 3 and the lower mounting rod 2 can be rotated to connect the upper mounting rod 3 and the lower mounting rod 2 with the support. With the support rod 1 parallel, the lower mounting rod 2 is pushed upward and the upper mounting rod 3 is pushed downward, so that the lower mounting rod 2 and the upper mounting rod 3 move along the slide groove 16 to the middle of the support rod 1 under the guidance of the slider 41; then the lower mounting rod 2 and the upper mounting rod 3 are locked and fixed by rotating the locking nut 44; finally, the snap-fit ​​rod 14 and snap-fit ​​shaft 15 between the lower support rod 11 and the upper support rod 12 are disengaged, and the support rod 1 is folded through the hinge 13; the display equipment is now stored, reducing the overall volume of the display equipment and making it easy to carry.

[0029] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
