Therefore, the above terms should not be construed as a limitation on this utility model. Secondly, the term "a" should be understood as "at least one" or "one or more," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. The term "a" should not be construed as a limitation on the quantity.

[0093] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 49 A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the storage device includes a folding storage box 10 and a telescopic pull rod 20 and a set of wheels 30 mounted on the folding storage box 10, and the user can pull the storage device by the telescopic pull rod 20.

[0094] Specifically, the telescopic rod 20 has an extended state and a retracted state, and the telescopic rod 20 can switch between the extended state and the retracted state. When the telescopic rod 20 is in the extended state, the telescopic rod 20 has a higher height dimension, so that the user can pull the storage device by the telescopic rod 20. When the telescopic rod 20 is in the retracted state, the telescopic rod 20 has a lower height dimension. For example, the top of the telescopic rod 20 may not protrude from the top of the folding storage box 10, so that the storage device can occupy less space.

[0095] In a specific example of the storage device of this utility model, the folding storage box 10 has an unfolded state and a folded state. The folding storage box 10 can switch between the unfolded state and the folded state. When the folding storage box 10 is in the unfolded state, it forms a storage cavity 11 for storing items. When the folding storage box 10 is in the folded state, it has a smaller size, and the storage device can occupy less space.

[0096] Reference Appendix Figures 1 to 36 , Figures 45 to 49The folding storage box 10 includes a front panel 12, a rear panel 13, two foldable side panels 14 in the middle, and a foldable bottom panel 15 in the middle. The front panel 12 and the rear panel 13 are arranged facing each other. One of the opposite sides of the side panel 14 is rotatably mounted to one side of the front panel 12 and one side of the rear panel 13, respectively. The other side panel 14 is rotatably mounted to the other side of the front panel 12 and the other side of the rear panel 13, respectively. One side of the bottom panel 15 is rotatably mounted to the bottom of the front panel 12. When the folding storage box 10 is in the folded state, both the side panels 14 and the bottom panel 15 are folded, and the folded side panels 14 and the folded bottom panel 15 are sandwiched between the front panel 12 and the rear panel 13. When the folding storage box 10 is in the unfolded state, both the side panels 14 and the bottom panel 15 are unfolded, and the edges of the unfolded bottom panel 15 rest against the bottom of the front panel 12, the bottom of the rear panel 13, and the bottom of the two side panels 14, respectively. Thus, the front panel 12, the rear panel 13, the two side panels 14, and the bottom panel 15 form the storage cavity 11 for storing items.

[0097] Unlike existing technologies, in this specific example of the storage device of this utility model, by designing the base plate 15 to be foldable in the middle, the storage cavity 11 formed by the unfolded folding storage box 10 has a larger capacity without increasing the height and width dimensions of the front plate 12 and the rear plate 13, or the height dimension of the side plate 14. In other words, since the height and width dimensions of the front plate 12 and the rear plate 13, as well as the height dimension of the side plate 14, are not increased, even if the width dimension of the side plate 14 and the length dimension of the base plate 15 are increased, the size of the folding storage box 10 after folding will not increase, thus making the folding storage box 10 smaller in size after folding.

[0098] Reference Appendix Figures 1 to 7The side panel 14 includes a first upright plate 141 and a second upright plate 142. One side of the first upright plate 141 and one side of the second upright plate 142 are rotatably mounted so that the middle of the side panel 14 is foldable. The side of the first upright plate 141 facing away from the second upright plate 142 is rotatably mounted to one side of the front panel 12, and the side of the second upright plate 142 facing away from the first upright plate 141 is rotatably mounted to one side of the rear panel 13. Thus, the opposite sides of the side panel 14 are rotatably mounted to one side of the front panel 12 and one side of the rear panel 13, respectively. By allowing the first upright plate 141 and the second upright plate 142 to rotate relative to each other, the side panel 14 can be folded and unfolded. It is understood that when the side panel 14 is folded, the first upright panel 141 and the second upright panel 142 are stacked, and the side panel 14 has a smaller width dimension so that both side panels 14 can be sandwiched between the front panel 12 and the rear panel 13. When the side panel 14 is unfolded, the first upright panel 141 and the second upright panel 142 are side by side, and the side panel 14 has a larger width dimension so that the storage cavity 11 of the folding storage box 10 has a larger capacity.

[0099] Reference Appendix Figure 4 , Figure 6 , Figure 8 , Figures 29 to 32 The base plate 15 includes a main base plate 151 and a secondary base plate 152 rotatably mounted on the main base plate 151. The side of the main base plate 151 facing away from the secondary base plate 152 is rotatably mounted to the bottom of the front plate 12. Specifically, the side of the main base plate 151 facing away from the secondary base plate 152 can be rotatably mounted to the bottom of the front plate 12 by having a convex shaft on each opposite side of the side of the main base plate 151 facing away from the secondary base plate 152, and a groove on each opposite side of the bottom of the front plate 12. Each convex shaft of the main base plate 151 is respectively disposed in each groove of the front plate 12, and each convex shaft of the main base plate 151 is configured to rotate within each groove of the front plate 12.

[0100] The base plate 15 can be folded and unfolded by allowing the main base plate 151 and the sub-base plate 152 to rotate relative to each other. Understandably, when the base plate 15 is folded, the main base plate 151 and the secondary base plate 152 are stacked, and the base plate 15 has a smaller size. This prevents the base plate 15 from protruding from the top of the front plate 12 after it is stacked on top of the front plate 12, thus ensuring that the storage device in the folded state has a smaller size. When the base plate 15 is unfolded, the main base plate 151 and the secondary base plate 152 are side by side, and the base plate 15 has a larger size. This allows the edges of the base plate 15 to rest against the bottom of the front plate 12, the bottom of the rear plate 13, and the bottoms of the two side plates 14, respectively. The front plate 12, the rear plate 13, the two side plates 14, and the base plate 15 together form the storage cavity 11, ensuring the load-bearing capacity of the base plate 15.

[0101] Continue to refer to the appendix Figures 29 to 32The base plate main board 151 has a row of first main board spindles 1511, a row of first main board shaft grooves 1512, and a row of first main board mounting arms 1513. The row of first main board spindles 1511 and the row of first main board shaft grooves 1512 are staggered, that is, there is a first main board shaft groove 1512 between two adjacent first main board spindles 1511, and there is a first main board spindle 1511 between two adjacent first main board shaft grooves 1512. The first main board mounting arms 1513 are located above the first main board shaft grooves 1512. The base plate sub-plate 152 has a row of first sub-plate rotating shafts 1521, a row of first sub-plate shaft grooves 1522, and a row of first sub-plate abutment arms 1523. The row of first sub-plate rotating shafts 1521 and the row of first sub-plate shaft grooves 1522 are staggered, that is, a first sub-plate shaft groove 1522 is provided between two adjacent first sub-plate rotating shafts 1521, and a first sub-plate rotating shaft 1521 is provided between two adjacent first sub-plate shaft grooves 1522. The first sub-plate abutment arms 1523 are located above the first sub-plate shaft grooves 1522. A row of first mainboard rotating shafts 1511 of the base plate main plate 151 extends to a row of first sub-plate shaft grooves 1522 of the base plate sub-plate 152, and a row of first sub-plate rotating shafts 1521 of the base plate sub-plate 152 extends to a row of first mainboard shaft grooves 1512 of the base plate main plate 151. The base plate 15 further includes a base plate mounting shaft 153, which is mounted in the shaft holes of the first main plate pivot 1511 of the main plate 151 and the shaft holes of the first secondary plate pivot 1521 of the secondary plate 152. Thus, the main plate 151 and the secondary plate 152 are rotatably mounted, allowing the middle portion of the base plate 15 to be folded. When the base plate 15 is unfolded, the first main plate abutment arms 1513 of the main plate 151 rest against the first secondary plate pivots 1521 of the secondary plate 152, and the first secondary plate abutment arms 1523 of the secondary plate 152 rest against the first main plate pivots 1511 of the main plate 151. This arrangement helps to improve the load-bearing capacity of the base plate 15.

[0102] Preferably, the base plate 15 further includes a base plate pull cord 154, which is disposed on the side of the base plate sub-plate 152 adjacent to the base plate main plate 151. When the folding storage box 10 is in the unfolded state, the base plate pull cord 154 is located in the storage cavity 11 of the folding storage box 10. The user can pull the base plate 15 upwards using the base plate pull cord 154 to rotate the base plate 15 relative to the front plate 12, thereby facilitating the folding of the base plate 15. After the base plate 15 is folded and stacked on the front plate 12, the base plate pull cord 154 faces the rear plate 13. The user can pull the base plate 15 downwards using the base plate pull cord 154 to rotate the base plate 15 relative to the front plate 12, thereby facilitating the unfolding of the base plate 15. It is worth mentioning that the specific manner in which the bottom plate pull cord 154 is set on the bottom plate sub-plate 152 is not limited in the storage device of this utility model, as long as one end of the bottom plate pull cord 154 can be reliably installed on the bottom plate sub-plate 152. Optionally, in other examples of the storage device of this utility model, the bottom plate pull cord 154 can be set on the side of the bottom plate main plate 151 adjacent to the bottom plate sub-plate 152.

[0103] Reference Appendix Figures 1 to 8 , Figures 33 to 36 , Figures 45 to 49 The rear panel 13 has an upward-opening rear panel cavity 131. The folding storage box 10 further includes a centrally foldable top panel 16, one side of which is rotatably and slidably mounted to the rear panel 13. When the top panel 16 is folded, it can be housed within the rear panel cavity 131 of the rear panel 13. When the top panel 16 is unfolded, its edges rest against the top of the front panel 12, the top of the rear panel 13, and the tops of the two side panels 14, respectively, to close the opening of the storage cavity 11 of the folding storage box 10 and ensure the load-bearing capacity of the top panel 16.

[0104] In this specific example of the storage device of this utility model, by designing the top plate 16 to be foldable in the middle, on the one hand, without increasing the height and width of the front plate 12 and the rear plate 13, and without increasing the height of the side plates 14, the unfolded top plate 16 can close the opening of the storage cavity 11 of the folding storage box 10, and each edge of the top plate 16 can rest against the top of the front plate 12, the top of the rear plate 13, and the tops of the two side plates 14, respectively, to ensure the load-bearing capacity of the top plate 16. That is to say, since the height and width of the front plate 12 and the rear plate 13, and the height of the side plates 14 are not increased, even if the length of the top plate 16 is increased, the size of the folding storage box 10 after folding will not increase, thus making the folding storage box 10 have a small size after folding.

[0105] Reference Appendix Figures 23 to 28 The rear plate 13 includes a rear plate main board 134 and a baffle 135, the baffle 135 being stacked on the rear plate main board 134, and a rear plate cavity 131 formed between the rear plate main board 134 and the baffle 135. In a specific example of the storage device of this utility model, after the baffle 135 is stacked on the rear plate main board 134, screws are used to install the baffle 135 and the rear plate main board 134, thereby forming the rear plate cavity 131 between the rear plate main board 134 and the baffle 135. After the folded top plate 16 is received in the rear plate cavity 131 of the rear plate 13, the rear plate main board 134 and the baffle 135 are located on opposite sides of the top plate 16. A wheel 30 is respectively installed on opposite sides of the bottom of the rear plate main board 134.

[0106] In this specific example of the storage device of the present invention, the rear main plate 134 has a rear plate arm 1341 on each of its opposite sides, and the side of the second upright plate 142 of the side plate 14 facing away from the first upright plate 141 is rotatably mounted to the rear plate arm 1341 of the rear main plate 134, thereby rotatably mounting the side plate 14 to the rear plate 13.

[0107] Continue to refer to the appendix Figure 3 , Figures 5 to 7 , Figures 33 to 36 , Figures 45 to 49The top plate 16 includes a main top plate 161 and a secondary top plate 162 rotatably mounted on the main top plate 161. The side of the main top plate 161 facing away from the secondary top plate 162 is rotatably and slidably mounted on the rear plate 13. Specifically, the side of the main top plate 161 facing away from the secondary top plate 162 can be rotatably mounted on the rear plate 13 by having a convex shaft on each opposite side of the side of the main top plate 161 facing away from the secondary top plate 162, and a groove on each opposite side of the rear plate 13. The two grooves are located on opposite sides of the rear plate cavity 131, and each convex shaft of the main top plate 161 is respectively disposed in each groove of the rear plate 13, and each convex shaft of the main top plate 161 is configured to slide and rotate within each groove of the rear plate 13.

[0108] The top plate 16 can be folded and unfolded by allowing the main top plate 161 and the secondary top plate 162 to rotate relative to each other. It is understood that when the top plate 16 is folded, the main top plate 161 and the secondary top plate 162 are stacked, and the top plate 16 has a smaller size, allowing it to be fully housed within the rear cavity 131 of the rear plate 13. When the top plate 16 is unfolded, the main top plate 161 and the secondary top plate 162 are side-by-side, and the top plate 16 has a larger size, allowing its edges to rest against the top of the front plate 12, the top of the rear plate 13, and the tops of the two side plates 14, respectively. This allows the top plate 16 to close the opening of the storage cavity 11 of the folding storage box 10 and ensure its load-bearing capacity.

[0109] Continue to refer to the appendix Figures 33 to 36The top plate mainboard 161 has a row of second mainboard pivots 1611, a row of second mainboard shaft grooves 1612, and a row of second mainboard support arms 1613. The row of second mainboard pivots 1611 and the row of second mainboard shaft grooves 1612 are staggered, that is, there is a second mainboard shaft groove 1612 between two adjacent second mainboard pivots 1611, and there is a second mainboard pivot 1611 between two adjacent second mainboard shaft grooves 1612. The second mainboard support arms 1613 are located above the second mainboard shaft grooves 1612. The top sub-plate 162 has a row of second sub-plate pivots 1621, a row of second sub-plate shaft grooves 1622, and a row of second sub-plate abutment arms 1623. The row of second sub-plate pivots 1621 and the row of second sub-plate shaft grooves 1622 are staggered, that is, a second sub-plate shaft groove 1622 is provided between two adjacent second sub-plate pivots 1621, and a second sub-plate pivot 1621 is provided between two adjacent second sub-plate shaft grooves 1622. The second sub-plate abutment arms 1623 are located above the second sub-plate shaft grooves 1622. A row of second main board pivots 1611 of the top main board 161 extends to a row of second sub-plate shaft grooves 1622 of the top sub-plate 162, and a row of second sub-plate pivots 1621 of the top sub-plate 162 extends to a row of second main board shaft grooves 1612 of the top main board 161. The top plate 16 further includes a top plate mounting shaft 163, which is mounted in the shaft holes of each of the second main plate pivots 1611 of the top plate main plate 161 and the shaft holes of each of the second secondary plate pivots 1621 of the top plate sub-plate 162. Thus, the top plate main plate 161 and the top plate sub-plate 162 are rotatably mounted, allowing the middle portion of the top plate 16 to be folded. When the top plate 16 is unfolded, each of the second main plate abutment arms 1613 of the top plate main plate 161 rests against each of the second secondary plate pivots 1621 of the top plate sub-plate 162, and each of the second secondary plate abutment arms 1623 of the top plate sub-plate 162 rests against each of the second main plate pivots 1611 of the top plate main plate 161. This arrangement helps to improve the load-bearing capacity of the top plate 16.

[0110] Preferably, the top plate 16 further includes a first top plate pull rope 164, which is disposed on the side of the main top plate 161 adjacent to the sub-top plate 162. (See attached diagram) Figures 45 to 49After the top plate 16 is unfolded, the first top plate pull cord 164 is exposed above the top plate 16. The user can pull the top plate 16 upwards using the first top plate pull cord 164. When the user pulls the top plate 16 upwards using the first top plate pull cord 164, on the one hand, the top plate 16 rotates relative to the rear plate 13. On the other hand, based on the weight of the top plate sub-plate 162, the top plate 16 automatically folds. When the top plate 16 rotates to the vertical position of the top plate main plate 161, the top plate sub-plate 162 is stacked on the top plate main plate 161, which facilitates the top plate 16 being housed in the rear plate cavity 131 of the rear plate 13. After the top plate 16 is housed in the rear plate cavity 131 of the rear plate 13, the first top plate pull cord 164 is exposed outside the rear plate cavity 131 of the rear plate 13, so that the user can pull the top plate 16 by the first top plate pull cord 164, causing the top plate 16 to slide out of the rear plate cavity 131 of the rear plate 13.

[0111] In addition, the top plate 16 further includes a second top plate pull rope 165, which is disposed on the side of the top plate sub-plate 162 opposite to the top plate main plate 161. The user can pull the top plate 16 upward by the second top plate pull rope 165 to open the cavity of the storage cavity 11 of the folding storage box 10.

[0112] It is worth mentioning that the specific manner in which the first top plate pull rope 164 is set on the main top plate 161 and the specific manner in which the second top plate pull rope 165 is set on the secondary top plate 162 are not limited in the storage device of this utility model, as long as one end of the first top plate pull rope 164 can be reliably installed on the main top plate 161 and one end of the second top plate pull rope 165 can be reliably installed on the secondary top plate 162.

[0113] Reference Appendix Figures 8 to 11The top of the side plate 14 has a pin cavity 143, and the top plate main plate 161 has at least one sliding groove 1614. The sliding groove 1614 has a top opening 16141 on the top surface of the top plate main plate 161 and a side opening 16142 on the side of the top plate main plate 161. After the top plate 16 is unfolded and the opening of the storage cavity 11 of the folding storage box 10 is closed, the position of the side opening 16142 of the sliding groove 1614 of the top plate main plate 161 corresponds to the position of the pin cavity 143 of the side plate 14. The top plate 16 further includes at least one pin element 166, the pin element 166 having an actuating end 1661 and an insertion end 1662 opposite to each other, the pin element 166 being slidably mounted in the slide groove 1614 of the main plate 161 of the top plate, the actuating end 1661 of the pin element 166 being located in the top opening 16141 of the slide groove 1614, and the insertion end 1662 of the pin element 166 being able to extend into the pin cavity 143 of the side plate 14 through the side opening 16142 of the slide groove 1614.

[0114] In other words, the insertion end 1662 of the latch element 166 can extend into and retract from the latch cavity 143 of the side plate 14. When the insertion end 1662 of the latch element 166 extends into the latch cavity 143 of the side plate 14, the latch element 166 locks the top plate 16 and the side plate 14 to prevent the top plate 16 from opening the opening of the storage cavity 11 of the folding storage box 10. When the insertion end 1662 of the latch element 166 retracts from the latch cavity 143 of the side plate 14, the latch element 166 releases the top plate 16 and the side plate 14 to allow the top plate 16 to close the opening of the storage cavity 11 of the folding storage box 10.

[0115] In the storage device of this utility model, the user can apply force to the pin element 166 through the actuating end 1661 of the pin element 166, so that the pin element 166 slides in the groove 1614 of the top plate main board 161, thereby allowing the insertion end 1662 of the pin element 166 to extend into or exit the pin cavity 143 of the side plate 14.

[0116] Preferably, in the appendix Figures 1 to 49 In this specific example of the storage device of the present invention shown, the pin cavity 143 of the side plate 14 is formed at the top of the first upright plate 141, that is, the pin element 166 is used to lock the top plate 16 to the first upright plate 141 of the side plate 14.

[0117] In the appendix Figures 1 to 49In this specific example of the storage device of the present invention, the top plate main board 161 has a groove 1614 on each of its opposite sides. Correspondingly, the top plate 16 includes two pin elements 166. Each of the grooves 1614 of the top plate main board 161 is provided with a pin element 166. In this way, each pin element 166 can lock the top plate 16 and each of the side plates 14 on the opposite sides of the top plate main board 161.

[0118] Reference Appendix Figure 12 , Figures 14 to 22 The front panel 12 includes a front panel main board 121 with a front panel through hole 1211. When the folding storage box 10 is in the unfolded state, the front panel through hole 1211 of the front panel main board 121 connects to the storage cavity 11 of the folding storage box 10. Thus, the user can store items into the storage cavity 11 of the folding storage box 10 through the front panel through hole 1211, and can also retrieve items from the storage cavity 11 of the folding storage box 10 through the front panel through hole 1211. A wheel 30 is respectively installed on each opposite side of the bottom of the front panel main board 121. In this specific example of the storage device of the present invention, the front panel 121 has a front panel arm 1215 on each of its opposite sides, and the side of the first upright plate 141 of the side plate 14 that is away from the second upright plate 142 is rotatably mounted to the front panel arm 1215 of the front panel 121, thereby rotatably mounting the side plate 14 to the front panel 12.

[0119] The front panel 12 further includes at least one door panel 122, which is operably mounted on the front panel main board 121. The door panel 122 is used to open and close the front panel through hole 1211 of the front panel main board 121. When the door panel 122 opens the front panel through hole 1211 of the front panel main board 121, the user can store items into the storage cavity 11 of the folding storage box 10 through the front panel through hole 1211 of the front panel main board 121, or take items out of the storage cavity 11 of the folding storage box 10 through the front panel through hole 1211 of the front panel 12.

[0120] In this specific example of the storage device of the present invention, the door panel 122 is slidably mounted on the front panel main board 121, that is, by driving the door panel 122 to slide relative to the front panel main board 121, the door panel 122 can be allowed to open or close the front panel through hole 1211 of the front panel main board 121.

[0121] Specifically, the front panel main board 121 has a pair of limiting grooves 1212 and a pair of guide posts 1213. The upper and lower sides of the front panel through-hole 1211 of the front panel main board 121 are respectively provided with the limiting groove 1212, and the guide posts 1213 protrude into the limiting grooves 1212. The upper and lower sides of the door panel 122 are respectively provided with guide grooves 1221. The upper and lower sides of the door panel 122 are slidably mounted on the respective limiting grooves 1212 of the front panel main board 121, and each guide post 1213 of the front panel main board 121 extends to the respective guide grooves 1221 of the door panel 122, so as to slidably mount the door panel 122 to the front panel main board 121. With this structure, the sliding direction of the door panel 122 is restricted to the horizontal direction, while preventing the door panel 122 from tilting during sliding, thus making the sliding process of the door panel 122 smoother.

[0122] Furthermore, the front panel 12 includes at least one door lock 123, the door lock 123 includes a door lock body 1231 and a door lock spring 1232, the middle part of the door lock body 1231 is rotatably mounted on the front panel main board 121, one end of the door lock spring 1232 abuts against the front panel main board 121, the other end of the door lock spring 1232 abuts against the top of the door lock body 1231, and the bottom of the door lock body 1231 has a door lock protrusion 12311. In order to ensure that the two ends of the door lock spring 1232 reliably abut against the top of the front panel main board 121 and the door lock body 1231 respectively, in a specific example of the storage device of this utility model, the front panel main board 121 has at least one first blind hole 1216, the top of the door lock body 1231 has a first protrusion 12312, the first protrusion 12312 of the door lock body 1231 protrudes into one end of the door lock spring 1232, and the other end of the door lock spring 1232 extends into the first blind hole 1216 of the front panel main board 121.

[0123] The top of the door panel 122 has a lock groove 1222. The lock protrusion 12311 of the lock body 1231 can extend into and retract from the lock groove 1222 of the door panel 122. When the lock protrusion 12311 of the lock body 1231 extends into the lock groove 1222 of the door panel 122, the door panel 122 is prevented from sliding relative to the front panel main board 121, that is, the door panel 122 is prevented from opening. When the lock protrusion 12311 of the lock body 1231 retracts from the lock groove 1222 of the door panel 122, the door panel 122 is allowed to slide relative to the front panel main board 121, that is, the door panel 122 is allowed to open.

[0124] Furthermore, the front panel 12 includes at least one pushing part 124, which is used to push the door panel 122 to slide a certain distance when the door lock protrusion 12311 of the door lock body 1231 exits the lock groove 1222 of the door panel 122, so as to facilitate the user to pull the door panel 122.

[0125] Specifically, the pushing part 124 includes a pushing block 1241 and a pushing spring 1242. The pushing block 1241 is slidably mounted on the front panel main board 121. One end of the pushing spring 1242 abuts against the front panel main board 121, and the other end of the pushing spring 1242 abuts against the pushing block 1241. When the door panel 221 is closed, the door panel 122 pushes the pushing block 1241 to slide relative to the front panel main board 121, thereby compressing the pushing spring 1242 and deforming it. When the door lock cam 12311 of the door lock body 1231 exits the lock groove 1222 of the door panel 122, the pushing spring 1242 pushes the pushing block 1241 to slide, so that the pushing block 1241 pushes the door panel 122 to slide a certain distance, so that the user can pull the door panel 122.

[0126] The specific manner in which the push block 1241 is slidably mounted on the front panel main board 121 is not limited in the storage device of this utility model. For example, in this specific example of the storage device of this utility model, refer to the attached... Figure 15 and Figure 17 The push block 1241 has a sliding wing 12411 on each of its opposite sides, and the front panel main board 121 has a pair of adjacent slide rails 1217 on its side. Each of the sliding wings 12411 of the push block 1241 extends to each of the slide rails 1217 of the front panel main board 121, and each of the sliding wings 12411 of the push block 1241 can slide along each of the slide rails 1217 of the front panel main board 121 to slidably mount the push block 1241 to the front panel main board 121.

[0127] Reference Appendix Figure 2 , Figure 5 , Figure 7 and Figure 13The folding storage box 10 further includes at least one flip-over compartment 17, which has a compartment 171 with a side opening. The bottom of the flip-over compartment 17 is rotatably mounted to the back plate 13, and the back plate 13 opens and closes the opening of the compartment 171 of the flip-over compartment 17. The compartment 171 of the flip-over compartment 17 is used to store small items. Because the bottom of the flip-over compartment 17 is rotatably mounted to the back plate 13, the flip-over compartment 17 can be operated whether the folding storage box 10 is in the folded state or the unfolded state, allowing the user to store small items in the compartment 171 of the flip-over compartment 17 and retrieve these items from the compartment 171 of the flip-over compartment 17.

[0128] Preferably, the rear plate 13 has a rear plate groove 132, the size of which matches the size of the flipping compartment 17. When the flipping compartment 17 is entirely located in the rear plate groove 132 of the rear plate 13, the flipping compartment 17 can be reliably held in the rear plate groove 132 of the rear plate 13 based on the friction generated between the flipping compartment 17 and the rear plate 13.

[0129] In the appendix Figures 1 to 49 In this specific example of the storage device of the present invention shown, the rear plate 13 has two rear plate slots 132, which are arranged along the height direction of the rear plate 13. Correspondingly, the number of flip-over compartments 17 is also two. One flip-over compartment 17 can be flipped to one of the rear plate slots 132 of the rear plate 13, and the other flip-over compartment 17 can be flipped to the other rear plate slot 132 of the rear plate 13.

[0130] Reference Appendix Figures 23 to 28At least one rear plate arm 1341 of the rear plate main board 134 of the rear plate 13 has a plate hole 13411, and at least one front plate arm 1215 of the front plate main board 121 has a locking arm 12151, the locking arm 12151 has a locking hole 121511, and the position of the locking arm 12151 of the front plate arm 1215 corresponds to the position of the plate hole 13411 of the rear plate arm 1341. The folding storage box 10 includes at least one plate lock 18, which includes a plate lock body 181 and a plate lock spring 182. The middle part of the plate lock body 181 is rotatably mounted to the rear plate arm 1341, and the plate lock body 181 is located in the plate hole 13411 of the rear plate arm 1341. One end of the plate lock body 181 has a plate lock protrusion 1811. One end of the plate lock spring 182 abuts against the rear plate main plate 134, and the other end of the plate lock spring 182 abuts against the other end of the plate lock body 181. When the folding storage box 10 is in the folded state, the locking arm 12151 of the front panel arm 1215 of the front panel main board 121 is inserted into the inner side of the rear panel arm 1341 of the rear panel main board 134, and the locking protrusion 1811 of the locking body 181 extends into the lock hole 121511 of the locking arm 12151 to prevent the front panel 12 and the rear panel 13 from moving away from each other, thereby ensuring that the folding storage box 10 is reliably maintained in the folded state. When the locking protrusion 1811 of the locking body 181 exits the lock hole 121511 of the locking arm 12151, the front panel 12 and the rear panel 13 can move away from each other, so that the folding storage box 10 can switch to the unfolded state.

[0131] Preferably, the plate lock body 181 has a second protrusion 1812 and a second blind hole 1813 formed in the second protrusion 1812, and one end of the plate lock spring 182 extends into the second blind hole 1813 of the plate lock body 181, so that the plate lock spring 182 can be reliably disposed between the plate lock body 181 and the rear plate main board 134.

[0132] In the appendix Figures 1 to 49In this specific example of the storage device of the present invention, the two rear plate arms 1341 of the rear plate main board 134 each have a plate hole 13411. The folding storage box 10 includes two plate locks 18. The plate lock bodies 181 of the two plate locks 18 are rotatably mounted on the two rear plate arms 1341 of the rear plate main board 134 and are respectively located in the two plate holes 13411. Correspondingly, the two front plate arms 1215 of the front plate main board 121 each have a locking arm 12151. After the folding storage box 10 is switched to the folded state, the two plate locks 18 lock the opposite sides of the front plate 12 on the opposite sides of the rear plate 13, so that the folding storage box 10 is reliably kept in the folded state.

[0133] Continue to refer to the appendix Figures 1 to 7 , Figure 12 , Figure 13 , Figures 37 to 44 The telescopic lever 20 includes a handle assembly 21 and two telescopic rod assemblies 22. The handle assembly 21 includes a handle 211, a button 212, a compression spring 213, and an unlocking unit 214. Each telescopic rod assembly 22 includes an outer tube 221, an inner tube 222, a first locking unit 223, a transmission rod 224, a sleeve 225, and a second locking unit 226.

[0134] Specifically, the handle 211 has a receiving cavity 2111, a button hole 2112, and two mounting holes 2113. The button hole 2112 communicates with the receiving cavity 2111 at the middle of the handle 211, and the mounting holes 2113 communicate with the receiving cavity 2111 at the ends of the handle 211. The button 212 is pressably mounted in the button hole 2112 of the handle 211. The bottom of the button 212 is located in the receiving cavity 2111 of the handle 211, and the top of the button 212 extends through the button hole 2112 of the handle 211 to the top of the handle 211. Thus, the button 212 is pressably mounted in the button hole 2112 of the handle 211, meaning that the user can press the button 212 from the outside of the handle 211, allowing the button 212 to move relative to the handle 211. The compression spring 213 is located in the receiving cavity 2111 of the handle 211. The opposite ends of the compression spring 213 abut against the handle 211 and the button 212 respectively. When the button 212 is pressed, the handle 211 and the button 212 cooperate to compress the compression spring 213. When the button 212 is released, the compression spring 213 can push the button 212 upward relative to the handle 211 to reset during the process of returning to the initial state. The unlocking unit 214 is housed in the receiving cavity 2111 of the handle 211. The unlocking unit 214 includes two inner levers 2141 and two outer levers 2142. The middle portions of the two inner levers 2141 and the middle portions of the two outer levers 2142 are rotatably mounted on the handle 211. The two inner levers 2141 are symmetrical to each other, and the two outer levers 2142 are symmetrical to each other. The inner end and outer end of the inner lever 2141 extend to the bottom of the button 212 and the bottom of the inner end of the outer lever 2142, respectively. The outer end of the outer lever 2142 extends to the top of the mounting hole 2113 of the handle 211.

[0135] The inner tube 222 is movably extended to an outer tube cavity 2211 of the outer tube 221. The top of the inner tube 222 is mounted in the mounting hole 2113 of the handle 211. The first locking unit 223 is mounted at the bottom of the inner tube 222. The transmission rod 224 is movably mounted vertically in an inner tube cavity 2221 of the inner tube 222, with the bottom of the transmission rod 224 abutting against the first locking unit 223. The top of the transmission rod 224 extends through the mounting hole 2113 of the handle 211 to the receiving cavity 2111, and abuts against the outer end of the outer lever 2142. The outer tube 221 is movably extended to a sleeve cavity 2251 of the sleeve 225. The second locking unit 226 is mounted at the bottom of the outer tube 221 and can abut against the first locking unit 223. The sleeve 225 is fixedly installed on the rear panel 13 to provide the telescopic pull rod 20 to the folding storage box 30. Specifically, the sleeve 225 is fixedly installed on the main board 134 of the rear panel.

[0136] When the button 212 is pressed down, on the one hand, the button 212 and the handle 211 cooperate to compress the compression spring 213, causing the compression spring 213 to deform and accumulate elastic potential energy. On the other hand, the button 212 pushes down the inner end of the inner lever 2141, causing the outer end of the inner lever 2141 to move upward. The outer end of the inner lever 2141 pushes the inner end of the outer lever 2142 to move upward, causing the outer end of the outer lever 2142 to move downward. The outer end of the outer lever 2142 pushes down the transmission rod 224. During the downward movement, the transmission rod 224 acts on the first locking unit 223, causing the first locking unit 223 to switch from a locked state to an unlocked state. The first locking unit 223 releases the outer tube 221, allowing the inner tube 222 to move relative to the outer tube 221, thereby allowing the telescopic lever 20 to switch from the retracted state to the extended state.

[0137] After the button 212 is released, on the one hand, the compression spring 213 pushes the button 212 during the process of returning to its initial state, so that the button 212 is reset. On the other hand, the first locking unit 224 can switch from the unlocked state to the locked state. During this process, the first locking unit 223 pushes the transmission rod 224 to move upward, the transmission rod 224 pushes the outer end of the outer lever 2142 to move upward, so that the inner end of the outer lever 2142 moves downward, and the inner end of the outer lever 2142 pushes the outer end of the inner lever 2141 to move downward, so that the inner end of the inner lever 2141 moves upward.

[0138] In the storage device of this utility model, the middle part of the inner lever 2141 and the middle part of the outer lever 2142 are rotatably mounted on the handle 211. This allows the handle assembly 21 to adopt a "lever" scheme. That is, when the button 212 is pressed, the inner lever 2141 and the outer lever 2142 cooperate with each other, allowing the outer end of the outer lever 2142 to move downward. In this way, the handle assembly 21 will not "get stuck" and there is no need to fill the receiving cavity 2111 of the handle 211 with lubricating oil. Therefore, the handle assembly 21 has higher reliability, lower cost, and does not need to consider sealing issues.

[0139] Specifically, see the attached document. Figures 37 to 44 The inner lever 2141 includes an inner rod 21411 and a pair of first pivots 21412, the pair of first pivots 21412 extending outward integrally from opposite sides of the middle portion of the inner rod 21411. The outer lever 2142 includes an outer rod 21421 and a pair of second pivots 21422, the pair of second pivots 21422 extending outward integrally from opposite sides of the middle portion of the outer rod 21421. The handle 211 has two pairs of first rotating holes 2114 and two pairs of second rotating holes 2115. A pair of first rotating shafts 21412 of the inner lever 2141 are rotatably mounted in the pair of first rotating holes 2114 of the handle 211, so as to rotatably mount the middle part of the inner lever 2141 to the handle 211. A pair of second rotating shafts 21422 of the outer lever 2142 are rotatably mounted in the pair of second rotating holes 2115 of the handle 211, so as to rotatably mount the middle part of the outer lever 2142 to the handle 211.

[0140] Further, the handle 211 includes a top cover 2116 and a bottom shell 2117, the top cover 2116 and the bottom shell 2117 being mounted to each other to form the receiving cavity 2111, the first rotating hole 2114 and the second rotating hole 2115 of the handle 2111 between the top cover 2116 and the bottom shell 2117, wherein the button hole 2112 of the handle 211 is formed in the middle of the top cover 2116 so that the button hole 2112 communicates with the receiving cavity 2111 in the middle of the handle 211, the mounting hole 2113 of the handle 211 is formed at the end of the bottom shell 2117 so that the mounting hole 2113 communicates with the receiving cavity 2111 at the end of the handle 211, and the first rotating hole 2114 and the second rotating hole 2115 of the handle 211 are both formed between the top cover 2116 and the bottom shell 2117.

[0141] Specifically, along the length of the bottom shell 2117, the bottom shell 2117 is provided with four pairs of shaft grooves 21171. Each pair of first rotating shafts 21412 of the two inner levers 2141 are respectively disposed in the two pairs of shaft grooves 21171 located in the middle of the bottom shell 2117. Each pair of second rotating shafts 21422 of the two outer levers 2142 are respectively disposed in the two pairs of shaft grooves 21171 located at the ends of the bottom shell 2117. After the top cover 2116 is installed on the bottom shell 2117, the top cover 2116 seals the openings of the shaft grooves 21171 of the bottom shell 2117. The two pairs of shaft grooves 21171 located in the middle of the bottom shell 2117 form the two pairs of first rotating holes 2114 of the handle 211, and the two pairs of shaft grooves 21171 located at the ends of the bottom shell 2117 form the two pairs of second rotating holes 2115 of the handle 211. Thus, a pair of first rotating shafts 21412 of the inner lever 2141 are rotatably mounted in a pair of first rotating holes 2114 of the handle 211, and a pair of second rotating shafts 21422 of the outer lever 2142 are rotatably mounted in a pair of second rotating holes 2115 of the handle 211.

[0142] It is worth mentioning that the installation method of the top cover 2116 and the bottom shell 2117 is not limited in the storage device of this utility model. For example, in the attached... Figures 1 to 49 In this specific example of the storage device of the present invention, the top cover 2116 has a plurality of mounting posts 21161. After the top cover 2116 is stacked on the bottom shell 2117, the mounting posts 21161 abut against the bottom shell 2117. Thus, after passing through the through hole in the bottom shell 2117, the screw can extend to the threaded hole of the mounting post 21161 and be screwed into the mounting post 21161, thereby reliably installing the top cover 2116 and the bottom shell 2117.

[0143] To avoid the mounting post 21161 of the top cover 2116, the inner lever 2141 has a first clearance hole 21413, and the outer lever 2142 has a second clearance hole 21423. At least one mounting post 21161 of the top cover 2116 abuts against the bottom shell 2117 after passing through the first clearance hole 21413 of the inner lever 2141, and at least one mounting post 21161 of the top cover 2116 abuts against the bottom shell 2117 after passing through the second clearance hole 21423 of the outer lever 2142. In this way, the mounting post 21161 of the top cover 2116 will not affect the rotation of the inner lever 2141 and the outer lever 2142.

[0144] Further, see attached document. Figures 37 to 44 The inner ends of the two inner levers 2141 overlap in the height direction, and the inner ends of the two inner levers 2141 form a clearance space 2140 to avoid the compression spring 213. In this way, on the one hand, the button 212 can be designed to have a smaller size, so that when the button 212 is pressed, the button 212 is not subjected to force on one side. On the other hand, when the button 212 is pressed, the inner ends of the two inner levers 2141 can be pressed down by the button 212 at the same time, so that the outer ends of the two outer levers 2142 can move down synchronously and with the same amplitude, so as to ensure that the unlocking unit 214 can unlock the first locking unit 223.

[0145] Continue to refer to the appendix Figures 37 to 44 The inner lever 2141 further includes an extension arm 21414, a support arm 21415, and a rest arm 21416. The extension arm 21414 and the support arm 21415 extend outward integrally from opposite sides of the inner end of the inner rod 21411, and the rest arm 21416 extends outward integrally from the end of the extension arm opposite to the inner rod 21411. The abutting arm 21416 of one inner lever 2141 rests against the supporting arm 21415 of another inner lever 2141, such that the inner ends of the two inner levers 2141 overlap in the height direction, and the extension arm 21414 and the abutting arm 21416 of one inner lever 2141 together with the extension arm 21414 and the abutting arm 21416 of the other inner lever 2141 form the clearance space 2140.

[0146] Further, see attached document. Figures 37 to 44 The supporting arm 21415 and the collapsing arm 21416 of the inner lever 2141 each have a notch 21417. The supporting arm 21415 of one inner lever 2141 extends to the notch 21417 of the collapsing arm 21416 of the other inner lever 2141, and the extension arm 21414 of one inner lever 2141 extends to the notch 21417 of the supporting arm 21415 of the other inner lever 2141. In this way, the top surfaces of the inner ends of the two inner levers 2141 are flush. When the button 212 is pressed down, the button 212 can drive the inner ends of the two inner levers 2141 to move down synchronously and with the same amplitude. Thus, when the button 212 is pressed, the two first locking units 223 can switch from the locked state to the unlocked state simultaneously.

[0147] Reference Appendix Figures 37 to 44 The bottom shell 2117 has a guide post 21172 with a guide hole 211721. The button 212 has an insertion post 2121, which is movably inserted into the guide hole 21172 of the guide post 21172 of the bottom shell 2117. The compression spring 213 is fitted into the guide post 211722 of the bottom shell 2117 and the insertion post 2121 of the button 212. In this way, on the one hand, the bottom shell 211... 7 can guide the movement direction of the button 212. When the button 212 is pressed, the bottom shell 2117 can prevent the button 212 from tilting, ensuring that the button 212 can drive the inner ends of the two inner levers 2141 to move downward synchronously and with the same amplitude. On the other hand, the guide post 21172 of the bottom shell 2117 and the insert post 2121 of the button 212 can prevent the compression spring 213 from tilting or shifting, so that the opposite ends of the compression spring 213 can reliably abut against the handle 211 and the button 212.

[0148] Optionally, in another specific example of the storage device of this utility model, the guide post 21172 can be provided on the button 212, and correspondingly, the insert post 2121 can be provided on the bottom shell 2117.

[0149] Continue to refer to the appendix Figures 42 to 44The first locking unit 223 further includes a first lock body 2231, a first locking pin 2232, a first locking spring 2233, and a first insertion arm 2234. The first lock body 2231 is installed at the bottom of the inner tube 222 to mount the first locking unit 223 at the bottom of the inner tube 222. Specifically, the top of the first lock body 2231 is inserted into the inner tube cavity 2221 of the inner tube 222. Based on the friction generated between the first lock body 2231 and the inner wall of the inner tube 222, the first lock body 2231 can be installed at the bottom of the inner tube 222. The first lock body 2231 has a first longitudinal hole 22311 and a first transverse hole 22312. The first longitudinal hole 22311 extends from the top surface of the first lock body 2231 towards the bottom surface, and the first transverse hole 22312 extends from the bottom of the first longitudinal hole 22311 to the side surface of the first lock body 2231. The first locking pin 2232 has a first locking end 22321 and a first driven end 22322. The first locking pin 2232 has an upward-facing first insertion hole 22323 at the first driven end 22322. One of the four faces of the first locking pin 2232 that defines the first insertion hole 22323, facing away from the first locking end 22321, is an inclined surface, defined as a first driven inclined surface 22324. The first locking pin 2232 is movably mounted in the first transverse hole 22312 of the first lock body 2231. The first locking spring 2233 is disposed in the first transverse hole 22312 of the first lock body 2231, and the opposite ends of the first locking spring 2233 abut against the first lock body 2231 and the first locking pin 2232, respectively. The bottom of the first insertion arm 2234 has a first driving slope 22341. The bottom of the first insertion arm 2234 extends through the first longitudinal hole 22311 of the first lock body 2231 to the first insertion hole 22323 of the first locking pin 2232. The first driving slope 22341 of the first insertion arm 2234 and the first driven slope 22324 of the first locking pin 2232 fit together. The top of the first insertion arm 2234 abuts against the transmission rod 224.The bottom of the outer tube 221 has an outer tube locking hole 2212, which is connected to the outer tube cavity 2211. The first locking end 22321 of the first locking pin 2232 can extend into and exit the outer tube locking hole 2212 of the outer tube 221. When the first locking end 22321 of the first locking pin 2232 extends into the outer tube locking hole 2212 of the outer tube 221, the first locking unit 223 is in the locked state, at which time the first locking unit 223 locks the outer tube 221. When the first locking end 22321 of the first locking pin 2232 exits the outer tube locking hole 2212 of the outer tube 221, the first locking unit 223 is in the unlocked state, at which time the first locking unit 223 releases the outer tube 221.

[0150] Continue to refer to the appendix Figures 42 to 44The second locking unit 226 further includes a second lock body 2261, a second locking pin 2262, a second locking spring 2263, and a second insertion arm 2264. The second lock body 2261 is installed at the bottom of the outer tube 221 to mount the second locking unit 226 at the bottom of the outer tube 221. Specifically, the top of the second lock body 2261 is inserted into the outer tube cavity 2211 of the outer tube 221, and based on the friction generated between the second lock body 2261 and the inner wall of the outer tube 221, the second lock body 2261 can be installed at the bottom of the outer tube 221. The second lock body 2261 has a second longitudinal hole 22611 and a second transverse hole 22612. The second longitudinal hole 22611 extends from the top surface of the second lock body 2261 towards the bottom surface, and the second transverse hole 22612 extends from the bottom of the second longitudinal hole 22611 to the side surface of the second lock body 2261. The second locking pin 2262 has a second locking end 22621 and a second driven end 22622. The second locking pin 2262 has an upward-facing second insertion hole 22623 at the second driven end 22622. One of the four faces of the second locking pin 2262 that defines the second insertion hole 22623, which is opposite to the second locking end 22621, is an inclined face, which is defined as a second driven inclined face 22624. The second locking pin 2262 is movably installed in the second transverse hole 22612 of the second lock body 2261. The second locking spring 2263 is disposed in the second transverse hole 22612 of the second lock body 2261, and the opposite ends of the second locking spring 2263 abut against the second lock body 2261 and the second locking pin 2262, respectively. The bottom of the second insertion arm 2264 has a second driving slope 22641. The bottom of the second insertion arm 2264 extends through the second longitudinal hole 22611 of the second lock body 2261 to the second insertion hole 22623 of the second locking pin 2262. The second driving slope 22641 of the second insertion arm 2264 and the second driven slope 22624 of the second locking pin 2262 fit together. The top of the second insertion arm 2264 abuts against the first lock body 2231.The bottom of the sleeve 225 has a sleeve locking hole 2252, which communicates with the sleeve cavity 2251. The second locking end 22621 of the second locking pin 2262 can extend into and exit the sleeve locking hole 2252 of the sleeve 225. When the second locking end 22621 of the second locking pin 2262 extends into the sleeve locking hole 2252 of the sleeve 225, the second locking unit 226 is in the locked state, at which time the second locking unit 226 locks the sleeve 225. When the second locking end 22621 of the second locking pin 2262 exits the sleeve locking hole 2252 of the sleeve 225, the second locking unit 226 is in the unlocked state, at which time the second locking unit 226 releases the sleeve.

[0151] When the telescopic rod 20 is in the retracted state, the first locking unit 223 is in the locked state. At this time, the first locking spring 2233 causes the first locking end 22321 of the first locking pin 2232 to extend into the outer tube locking hole 2212 of the outer tube 221, so as to prevent the inner tube 222 from moving relative to the outer tube 221. The second locking unit 226 is in the unlocked state. At this time, the second locking end 22621 of the second locking pin 2262 is blocked by the inner wall of the sleeve 225. The second locking pin 2262 and the second lock body 2261 cooperate to compress the second locking spring 2263, so that the second locking spring 2263 accumulates elastic potential energy due to compression.

[0152] When the button 212 is pressed down, on the one hand, the button 212 and the handle 211 cooperate to compress the compression spring 213, causing the compression spring 213 to deform and accumulate elastic potential energy. On the other hand, the button 212 pushes down the inner end of the inner lever 2141. The inner lever 2141 and the outer lever 2142 cooperate to move the outer end of the outer lever 2142 downward. During the downward movement of the outer end of the outer lever 2142, the transmission rod 224 is pushed downward. During the downward movement of the transmission rod 224, the first insertion arm 2234 is pushed downward. When the first insertion arm 2234's first driving inclined surface 22341 and the first driven inclined surface 22324 of the first locking pin 2232 cooperate with each other, the first locking pin 2232 moves within the first transverse hole 22312 of the first lock body 2231 and exits the outer tube locking hole 2212 at the bottom of the outer tube 221. The first locking pin 2232 and the first lock body 2231 compress the first locking spring 2233, causing the first locking spring 2233 to deform and accumulate elastic potential energy. At this time, the first locking unit 223 switches from the locked state to the unlocked state. After the inner tube 222 is pulled to move relative to the outer tube 221, the button 212 can be released. The compression spring 213 pushes the button 212 during the process of returning to the initial state, so that the button 212 is reset. After the inner tube 222 moves to the first locking end 22321 of the first locking pin 2232 of the first locking unit 223 and aligns with the outer tube locking hole 2212 at the top of the outer tube 221, the first locking spring 2233 pushes the first locking pin 2232 to move in the first transverse hole 22312 of the first lock body 2231 and extend into the outer tube locking hole 2212 at the top of the outer tube 221. The first locking unit 223 switches from the unlocked state to the locked state to prevent the inner tube 222 from moving relative to the outer tube 221. After the outer tube 221 is pulled to move relative to the sleeve 225, there is a gap between the first locking unit 223 and the bottom and the second insertion arm 2264 of the second locking unit 226. After the outer tube 221 moves to the position where the second locking end 22621 of the second locking pin 2262 of the second locking unit 226 is aligned with the sleeve locking hole 2252 of the sleeve 225, the second locking spring 2263 pushes the second locking pin 2262 to move in the second transverse hole 22612 of the second lock body 2261 and extend into the sleeve locking hole 2252 of the sleeve 225. The second locking unit 226 switches from the unlocked state to the locked state to prevent the outer tube 221 from moving relative to the sleeve 225.Through the above process, the telescopic rod 20 switches from the retracted state to the extended state. The process of switching the telescopic rod 20 from the extended state to the retracted state is the same as the process of switching the telescopic rod 20 from the retracted state to the extended state, and will not be described again.
