[0013] The advantages of this invention compared to existing technologies are as follows: By pulling the connecting plate, the connecting plate drives the movable sleeve to slide via the insert rod. The movable sleeve drives the second placement plate and the first placement plate to rotate sequentially via the rotating mechanism. The second placement plate can rotate via the limiting mechanism. The two first placement plates and the second placement plate are fixed by the fixing rod, spring one, and auxiliary fixing mechanism. During the rotation of the first and second placement plates, the auxiliary fixing mechanism drives the transmission mechanism one and the transmission mechanism two, causing the first fixed sleeve to extend out of the groove one and the second fixed sleeve to rotate, thereby facilitating the retrieval of tools. The movable sleeve is fixed by the sleeve fixing mechanism, allowing the placement rack to be folded for easy carrying. Specifically, as follows:

[0014] 1. Pull the connecting plate. The connecting plate drives the movable sleeve to move through the insert rod. The movable sleeve drives the rotating shaft one and rotating shaft two to rotate through the rotating mechanism, so that the first placement plate and the second placement plate change from a vertical state to a horizontal state.

[0015] 2. The limiting mechanism can limit the rotation of the second rotating shaft, so that after the rotation is completed, the second placement plate can move upward with the movable sleeve, thereby realizing the layering of the placement rack.

[0016] 3. After the first and second placement plates change from a vertical to a horizontal state, spring one pushes the fixing rod into the limiting hole on the movable sleeve. The rack two at one end of the fixing rod slides and drives the gear three to rotate. The rotation of the gear three drives the rack three at one end of the slide rod to slide. The rack three moves away from the gear three. Spring two pushes the slide rod to slide. The slide rod drives the L-shaped rod to slide, thereby inserting it into the corresponding insertion hole one.

[0017] 4. The movement of the L-shaped rod drives the movement of moving rod one and moving rod two. The movement of rack four and rack five on moving rod one and moving rod two drives the rotation of gear four and gear five. The rotation of gear four drives the stud to rotate. The stud drives the fixed sleeve one to move horizontally through the threaded sleeve, so that the fixed sleeve one extends out of the groove one, thus not interfering with the rotation of the second placement plate. Gear five drives the fixed shaft to rotate, thereby driving the fixed sleeve two to rotate, so that the fixed sleeve two changes from a vertical state to a horizontal state, making it easier to pick up the tool.

[0018] 5. The movable sleeve moves the slider upward. When it contacts the fixed groove on the fixed sleeve, the spring causes the slider to slide, and the slider enters the fixed groove, fixing the movable sleeve on the fixed sleeve, thus completing the opening of the placement rack.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 5 Appendix Figure 11 Appendix Figure 13As shown, a foldable tool holder for power equipment maintenance includes a base 1. The base 1 has four fixed sleeves 2 at its four corners. A first placement plate 3 and a second placement plate 4 are respectively provided on both sides of the fixed sleeves 2. The fixed sleeves 2 have sliding holes 5 and sliding grooves 6 that mate with the first placement plates 3 and 4. The first placement plate 3 has rotating shafts 7 located within the sliding holes 5 on both sides, and the second placement plate 4 has rotating shafts 8 located within the sliding grooves 6 on both sides. A movable sleeve 9 is movably inserted into the fixed sleeve 2. The movable sleeve 9 has a rotating mechanism 12 that allows the movable sleeve 9 to slide and drive the rotating shafts 7 and 8 to rotate. The fixed sleeve 2 has a limiting mechanism 13 located within the sliding grooves 6 that cooperates with the second placement plate 4 to rotate first and then slide. A fixed rod 14 is movably inserted into the rotating shafts 7 and 8. A spring 15 is provided between the fixed rod 14 and the rotating shafts 7 and 8. The movable sleeve 9 is provided with a limiting hole that cooperates with the fixed rod 14. The first placement plate 3 and the second placement plate 4 are provided with an auxiliary fixing mechanism 32 triggered by the fixed rod 14. The movable sleeve 9 is provided with a through hole 16 that cooperates with the fixed rod 14. The first placement plate 3 and the second placement plate 4 are respectively provided with a first groove 17 and a second groove. A first fixing sleeve 19 is slidably provided in the first groove 17, and a second fixing sleeve 20 is rotatably provided in the second groove. The first placement plate 3 is provided with a first transmission mechanism 21 that moves the auxiliary fixing mechanism 32 to drive the first fixing sleeve 19 to slide. The second placement plate 4 is provided with a second transmission mechanism 22 that moves the auxiliary fixing mechanism 32 to drive the second fixing sleeve 20 to rotate. The movable sleeve 9 is provided with a connecting plate 10. The bottom surface of the connecting plate 10 is provided with a first insertion rod 11 that cooperates with the movable sleeve 9. The movable sleeve 9 is provided with a sleeve fixing mechanism 23 that is triggered by the first insertion rod 11 to cooperate with the fixed sleeve 2.

[0035] The working principle of this invention: In the initial state, spring 15 is in a compressed state. By moving the connecting plate 10, the connecting plate 10 drives the movable sleeve 9 to move upward through the insert rod 11. The slide groove 25 on the movable sleeve 9 moves upward, and the rack 27 in the slide groove 25 contacts the gear 26 on the rotating shaft 8. The rotating shaft 8 is limited by the limiting mechanism 13. The rack 27 moves upward and drives the gear 26 to rotate, thereby driving the second placement plate 4 to rotate. When the second placement plate 4 changes from a vertical state to a horizontal state, the fixing rod 14 enters the through hole 16 on the movable sleeve 9. The fixing rod 14 moves and drives the auxiliary fixing mechanism 32. The auxiliary fixing mechanism 32 further fixes the second placement plate 4. At this time, the limiting mechanism 13 no longer limits the rotating shaft 8. The second placement plate 4 moves upward with the movable sleeve 9, away from the slide groove 16. Then the rack 27 in the slide groove 24 and the gear 26 in the slide groove 25 contact the gear 26 on the rotating shaft 8. Gear 26 on shaft 7 contacts, and then the movable sleeve 9 drives the first placement plate 3 to rise through rack 27 and gear 26, reaching one end of the sliding hole 5. Rack 27 rises and drives gear 26 to rotate, thereby rotating the first placement plate 3. When the first placement plate 3 changes from a vertical state to a horizontal state, the fixing rod 14 enters the through hole 16 on the movable sleeve 9. The fixing rod 14 moves to drive the auxiliary fixing mechanism 32, which further fixes the first placement plate 3. The auxiliary fixing mechanism 32 drives the transmission mechanism 21 and the transmission mechanism 22, respectively causing the fixing sleeve 19 to translate and the fixing sleeve 20 to rotate. By setting the fixing sleeve 19 in the groove 17, it will not affect the rotation of the second placement plate 4. By making the fixing sleeve 20 rotate, it is convenient to take out the tool. The movable sleeve 9 is fixed on the fixing sleeve 2 by the sleeve fixing mechanism 23.

[0036] Combined with appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 8 As shown, the rotating mechanism 12 includes a second groove 24 and a third groove 25 that respectively cooperate with the first rotating shaft 7 and the second rotating shaft 8. One end of the first rotating shaft 7 and the second rotating shaft 8 is provided with a gear 26, and the second groove 24 and the third groove 25 are provided with a rack 27 that cooperates with the gear 26.

[0037] Working principle of rotating mechanism 12: When the movable sleeve 9 moves upward, the rack 27 in the second slide groove 24 and the third slide groove 25 moves upward. The rack 27 drives the gear 26 on the rotating shaft 7 and the rotating shaft 8 to rotate, thereby driving the first placement plate 3 and the second placement plate 4 to rotate.

[0038] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 4As shown, the limiting mechanism 13 includes a sliding groove 6 with a rotating groove 28 located on the inner wall of the end. A sector block 29 is rotatably disposed in the rotating groove 28. A gear 30 is rotatably disposed on the inner wall of one end of the sliding groove 6. A sector gear 31 that cooperates with the gear 30 is disposed on the sector block 29. A gear groove 65 that cooperates with the gear 30 is disposed on the rotating shaft 8.

[0039] Working principle of limiting mechanism 13: In the initial state, sector block 29 and slide 6 together limit the rotating shaft 8. The rack 27 in slide 3 25 moves and drives gear 26 to rotate. Gear 26 rotates and drives gear 30 to rotate. Gear 30 rotates and drives sector gear 31 on sector block 29 to rotate. Sector block 29 gradually enters the rotating groove 28. When the second placement plate 4 is in a horizontal state, sector block 29 is completely entered into the rotating groove 28.

[0040] Combined with appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 As shown, the auxiliary fixing mechanism 32 includes a rack 33 at one end of a fixing rod 14, a gear 34 rotatably disposed within the first placement plate 3 and the second placement plate 4, a sliding rod 35 slidably disposed within the first placement plate 3 and the second placement plate 4, a rack 36 at one end of the sliding rod 35 meshing with the gear 34, a spring 37 between the sliding rod 35 and the first placement plate 3 and the second placement plate 4, an L-shaped rod 38 slidably disposed within the first placement plate 3 and the second placement plate 4 and connected to the sliding rod 35, a connecting post 68 at one end of the gear 34, a transmission gear 57 disposed on the connecting post 68, a transmission rod 46 disposed on one side of the L-shaped rod 38, a transmission rack 18 on the transmission rod 46 that meshes with the transmission gear 57, and staggered limiting blocks 39 disposed on the bottom surface of the first placement plate 3 and the second placement plate 4, each limiting block 39 having an insertion hole that meshes with the L-shaped rod 38.

[0041] Working principle of auxiliary fixing mechanism 32: In the initial state, spring 2 37 is in a compressed state, the movable sleeve 9 moves upward, and the rack 1 27 in the slide groove 3 25 drives the gear 1 26 on the rotating shaft 2 8 to rotate. When the second placement plate 4 is in a horizontal state, the through hole 16 on the movable sleeve 9 is on the same plane as the fixed rod 14. Spring 1 15 pushes the fixed rod 14 into the through hole 16. The rack 2 33 at one end of the fixed rod 14 drives the gear 3 34 to rotate. The gear 3 34 drives the rack 3 36 at one end of the slide rod 35 to move. When the rack 3 36 is no longer in contact with the gear 3 34, spring 2 37 pushes the slide rod 35 to slide horizontally. The slide rod 35 drives L The L-shaped rod 38 moves horizontally, causing it to enter the insertion hole 1 on the other second placement plate 4. At this time, the transmission rack 18 on the transmission rod 46 meshes with the transmission gear 57. When it is necessary to release the fixation, the movable sleeve 9 moves downward, and the insertion rod 11 pushes the fixing rod 14 to move horizontally. The fixing rod 14 drives the gear 34 to rotate through the rack 2 33. The gear 34 drives the transmission gear 57 to rotate through the connecting column 68. The rotation of the transmission gear 57 drives the transmission rod 46 to move horizontally, thereby moving the L-shaped rod 38 away from the insertion hole 1 on the other second placement plate 4. Then the first placement plate 3 works on the same principle as above, and will not be described in detail.

[0042] Combined with appendix Figure 6 Appendix Figure 7 As shown, the transmission mechanism 21 includes a movable rod 40 that is slidably disposed in the first placement plate 3 and connected to an L-shaped rod 38 on one side. The fixed sleeve 19 has a threaded sleeve 41 on one side, and a stud 42 is threadedly connected to the threaded sleeve 41. A gear 43 is provided at one end of the stud 42, and a rack 44 that meshes with the gear 43 is provided on the movable rod 40.

[0043] Working principle of transmission mechanism 121: The L-shaped rod 38 in the auxiliary fixing mechanism 32 moves, which drives the moving rod 140 to move. The moving rod 140 moves, which drives the rack 44 to move. The rack 44 drives the gear 43 to rotate. The gear 43 drives the stud 42 to rotate. The rotation of the stud 42 drives the threaded sleeve 41 to move horizontally, thereby causing the fixing sleeve 19 to move horizontally.

[0044] Combined with appendix Figure 5 Appendix Figure 6 As shown, the transmission mechanism 22 includes a movable rod 45 that is slidably disposed in the second placement plate 4 and connected to an L-shaped rod 38 on one side. One end of the fixed sleeve 20 is provided with a fixed shaft, and one end of the fixed shaft is provided with a gear 47. The movable rod 45 is provided with a rack 48 that meshes with the gear 47.

[0045] Working principle of transmission mechanism 22: The L-shaped rod 38 in the auxiliary fixing mechanism 32 moves, which drives the moving rod 2 45 to move. The rack 5 48 on the moving rod 2 45 moves, which drives the gear 5 47 to rotate. The rotation of the gear 5 47 drives the fixing sleeve 20 to rotate.

[0046] Combined with appendix Figure 2 Appendix Figure 11 As shown, the sleeve fixing mechanism 23 includes a slider 49 slidably disposed in the movable sleeve 9, an extension rod 50 on one side of the slider 49, a sector block 51 at one end of the extension rod 50, a spring 52 between the slider 49 and the movable sleeve 9, a drive groove 53 at one end of the insertion rod 11 that cooperates with the sector block 51, and a fixing groove in the fixed sleeve 2 that cooperates with the slider 49.

[0047] Working principle of sleeve fixing mechanism 23: In the initial state, spring 3 52 is in a compressed state. The connecting plate 10 drives the movable sleeve 9 to move upward through the insertion rod 11. When the slider 49 moves to the fixing groove on the fixed sleeve 2, spring 3 52 pushes the slider 49 into the fixing groove to complete the fixing of the movable sleeve 9.

[0048] Combined with appendix Figure 9 Appendix Figure 10 Appendix Figure 11 As shown, the insertion rod 11 is provided with a slot 54, and a locking block 55 is slidably provided in the slot 54. A spring 56 is provided between the locking block 55 and the slot 54. The connecting plate 10 is provided with a slot 2 extending into the insertion rod 11. An insertion rod 58 is movably inserted into the slot 2. The connecting plate 10 is provided with a connecting rod 66 connected to the insertion rod 58. A return spring 67 is provided between the connecting rod 66 and the connecting plate 10 and sleeved on the insertion rod 58. The locking block 55 is provided with a driving hole 59. The insertion rod 58 is provided with an inclined groove that cooperates with the driving hole 59. The fixed sleeve 2 and the movable sleeve 9 are provided with insertion holes 2 that cooperate with the locking block 55.

[0049] Working principle: In the initial state, spring 4 56 and return spring 67 are in the relaxed state. Pressing the connecting rod 66 causes the insert rod 2 58 to move downward. The return spring 67 is compressed and deformed. The insert rod 2 58 moves the locking block 55 through the inclined groove. The spring 4 56 is compressed and deformed. The locking block 55 moves away from the insertion hole 2 on the fixed sleeve 2 and the movable sleeve 9. Then the connecting plate 10 is lifted upward. The connecting plate 10 causes the insert rod 1 11 to move upward. The connecting rod 66 is released. The return spring 67 pushes the connecting rod 66 to reset. The locking block 55 is pushed against the inner wall of the movable sleeve 9 by the force of the spring 4 56. When the locking block 55 is connected to the other insertion hole 2 of the movable sleeve 9, the spring 4 56 pushes the locking block 55 to move, thus entering the insertion hole 2 on the movable sleeve 9.

[0050] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 9 Appendix Figure 10 Appendix Figure 12 As shown, the bottom surface of the connecting plate 10 is provided with a connecting block 60, the connecting block 60 is provided with a rotating groove, a rotating sleeve 61 is rotatably provided in the rotating groove on the first placement plate 3, a push block 62 is movably inserted into the rotating sleeve 61, a spring 63 is provided between the push block 62 and the rotating sleeve 61, a push block 64 is rotatably provided in the rotating groove on the second placement plate 4, a through groove is provided on one side of the first placement plate 3 and the second placement plate 4, and an extension plate located in the through groove is provided on the slide rod 35.

[0051] Working principle: In the initial state, spring 63 is in a relaxed state. When it is necessary to reset the auxiliary fixing mechanism, the connecting plate 10 is pushed down. The connecting plate 10 drives the connecting block 60 to move downward. The push block 62 located on the side of the first placement plate 3 first enters the through groove. Then, during the downward movement of the connecting plate 10, it gradually pushes the extension plate to move horizontally. As the distance between the connecting plate 10 and the first placement plate 3 gradually decreases, the push block 62 gradually slides into the rotating sleeve 61. The spring 63 is compressed and deformed, gradually pushing the rack 36 on the slide rod 35 to mesh with the gear 34.

[0052] In practical use, pressing the connecting rod 66 causes the insert rod 58 to move downwards, passing through the inclined groove and drive hole 59. The insert rod 58 then causes the locking block 55 to slide, separating it from the insertion hole 2 on the fixed sleeve 2 and the movable sleeve 9. Then, the connecting plate 10 is pushed upwards, causing the insert rod 58 to move upwards. When it reaches another insertion hole 2, the spring 4 56 pushes the locking block 55 to slide, allowing it to enter the insertion hole 2 on the movable sleeve 9. Continuing to push the connecting plate 10 causes the movable sleeve 9 to move upwards, where the rack 27 in the sliding groove 3 25 engages with the gear 1 on the rotating shaft 2 8. 26 meshes, rack 27 moves upward, driving shaft 8 to rotate, the second placement plate 4 changes from a vertical state to a horizontal state, fixing rod 14 moves, driving auxiliary fixing mechanism 32 to further fix the second placement plate 4, auxiliary fixing mechanism 32 drives transmission mechanism 22 to rotate fixing sleeve 20, limiting mechanism 13 changes from a closed state to an open state, then movable sleeve 9 drives the second placement plate 4 to move upward, through rack 27 on movable sleeve 9 and gear 26 on first placement plate 3, the first placement plate 3 first rises and then rotates, after the first placement plate 3 has rotated, auxiliary fixing mechanism 32 drives transmission mechanism 22 to rotate. The actuating mechanism 21 moves the fixed sleeve 19 horizontally, and the slider 49 enters the fixing groove in the fixed sleeve 2, thus fixing the movable sleeve 9. When folding is required, the connecting rod 66 is pressed, and the connecting rod 66 drives the insert rod 58 to move downward. Through the inclined groove and the driving hole 59, the insert rod 58 drives the locking block 55 to slide, and the locking block 55 separates from the second insertion hole on the movable sleeve 9. Then, the connecting plate 10 is pushed downward, and the insert rod 58 pushes the fixing rod 14 on the first placement plate 3 to move horizontally, so that it enters the rotating shaft 7. The L-shaped rod 38 on the auxiliary fixing mechanism 32 moves away from the second insertion hole on the other first placement plate 3. Then, the first placement plate 3 is rotated by rack 27 and gear 26, changing from a horizontal to a vertical state. Then, the second placement plate 4 is rotated by rack 27 and gear 26, changing from a horizontal to a vertical state. The limiting mechanism 13 returns to its initial position. Then, the auxiliary fixing mechanism 32 on the first placement plate 3 is reset by rotating sleeve 61, spring 63, and push block 62.
