[0017] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0018] With reference to Figures 1 to 4 A combined tool box 100 comprises a box body 10 with a holding opening 101 and a locking opening 102, a locking member 20 rotatably installed on the box body 10, and a swing reset member 30 installed on the box body 10 and capable of driving the locking member 20 to embrace the center from one side of the box body 10, and the swing reset member 30 is preferably a torsion spring. The locking member 20 comprises a main body 201, a touch portion 202 arranged at one end of the main body 201, and a locking portion 203 arranged at the other end of the main body 201. The touch portion 202 is located at the holding opening 101, and the locking portion 203 is located at one side of the locking opening 102 of the adjacent box body 10. The main body 201 of the locking member 20 is hinged to the box body 10 through a pin shaft 40, the swing reset member 30 is sleeved on the pin shaft 40, one end of the swing reset member 30 is connected to the pin shaft 40, and the other end is connected to the main body 201.

[0019] With reference to Figures 5 to 11 The locking opening 102 is provided with an inclined limiting portion 50, when the adjacent box body 10 is locked, the locking portion 203 of the locking member 20 extends into the locking opening 102 of the lower box body 10 and engages with the inclined limiting portion 50.

[0020] Further, the side surface of the box body 10 is provided with a first inclined extrusion surface 103, and the locking portion 203 is provided with a second inclined extrusion surface 204 corresponding to the first inclined extrusion surface 103.

[0021] Further, the bottom of the box body 10 is provided with a protruding support portion 60, and the top of the box body 10 is provided with a recessed portion 70. When the two box bodies 10 are stacked, the support portion 60 at the bottom of the box body 10 is matched with the recessed portion 70 at the top of the adjacent box body 10, and the bottom surface of the support portion 60 is flush with the end of the locking member 20.

[0022] In some embodiments, the top of the box 10 is provided with a handle 80, which is arranged in a rotatable folding state. The recess 70 is provided with a groove 90, and the handle 80 can be stored in the groove 90 when not in use. When two adjacent boxes 10 are stacked, the user will habitually lift the box 10 by the handle 80 during the stacking operation, and place the lifted box 10 above the lower box 10. When the user releases the handle 80, the support portion 60 of the upper box is fitted with the recess 70 of the lower box, and at the same time, the self-gravity of the upper box can lock the two stacked boxes 10 with each other. At this time, the handle 80 in the groove 90 of the lower box is covered by the upper box and is not exposed.

[0023] Through the above structure design, when the adjacent boxes 10 are stacked, the locking portion 203 is automatically locked with the locking port 102 on the adjacent box 10, so that the adjacent stacked boxes 10 are locked and fixed with each other. When the user applies a touch action to the touch portion 202, the touch portion 202 can drive the locking portion 203 to change from the embracing state to the open state, so that the locking portion 203 is separated from the locking port 102 on the adjacent box 10, and the locking state between the adjacent stacked boxes 10 is released.

[0024] The locking process between the two adjacent boxes 10 and the process of releasing the locking state will be described in detail below in combination with specific structures.

[0025] When the adjacent boxes 10 are stacked, the upper box is set as 10a, and the lower box is set as 10b. After the upper box 10a is stacked on the top of the lower box 10b, the support portion 60 at the bottom of the upper box 10a is aligned with the recess 70 at the top of the lower box 10b. At this time, the locking member 20 on the upper box 10a is aligned with the locking port 102 on the lower box 10b. Under the action of the gravity of the upper box 10a, the second inclined pressing surface 204 of the locking portion 203 on the upper box 10a is in contact with the first inclined pressing surface 103 on the lower box 10b. Under the action of the gravity of the upper box 10a, the first inclined pressing surface 103 exerts a pressing force on the second inclined pressing surface 204, so that the locking portion 203 on the upper box 10a expands toward one side of the lower box 10b. When the second inclined pressing surface 204 of the locking portion 203 is separated from the first inclined pressing surface 103 on the lower box 10b, the swing reset member 30 drives the locking portion 203 to embrace the middle portion of the lower box 10b, and locks with the locking port 102 on the lower box 10b.

[0026] When the unlocked state of the two stacked boxes needs to be released, a hand applies a touch action to the touch part 202. Specifically, the hand is inserted into the holding opening 101 of the upper box 10a and pushes the touch part 202. The touch part 202 drives the locking part 203 to change from the embracing state to the open state, so that the locking part 203 is separated from the locking opening 102 on the lower box 10b. The locking state between the stacked adjacent boxes is released. After the hand lifts the upper box 10a through the holding opening 101, the upper box 10a can be separated from the lower box 10b.

[0027] When the multiple boxes 10 of the combined tool box are stacked, the support part 60 and the recessed part 70 of two adjacent boxes 10 are aligned. Under the action of the gravity of the box 10, the locking part 20 installed thereon is automatically locked with the locking opening 102 on the adjacent box. When the two adjacent boxes 10 need to be separated, the hand is inserted into the holding opening 101 and pushes the touch part 202 of the locking part 20. The locking state of the locking part 203 of the locking part 20 and the locking opening 102 on the adjacent box 10 is automatically released. At the same time, the lifting force applied by the hand at the holding opening 101 can drive the upper box and the lower box to be separated. The boxes of the combined tool box can be automatically locked when stacked, and the locking state between the adjacent boxes is automatically released when lifted. The locking action and the locking state release action between the two boxes 10 are omitted. The operation is convenient and fast.

[0028] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
