Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] like Figure 1 , Figure 2 As shown, a lever toolbox includes a lid 1, a box body 2 with an open top, a latch 3, a lever 4, a base plate 5, a movable cover 6, and a support rod 7.

[0047] The tie rod 4 includes a horizontal tie rod 41 and two longitudinal telescopic rods 42, with the longitudinal telescopic rods 42 and the horizontal tie rod 41 fixed at both ends; that is, the double tie rod technology in the prior art;

[0048] The base plate 5 includes an accommodating cavity 51 with openings at the top and bottom, telescopic rod cavities 52 located on both sides of the accommodating cavity 51, and a support rod hole 53; the telescopic rod cavity 52 has an upper opening and an end opening at one end.

[0049] The movable cover 6 is provided with four upper-opening support cavities 61, which can also be called rod cavities;

[0050] The rear of the lid 1 and the rear of the body 2 are pivotally connected. The latch 3 is hinged to the lid 1 and locks the lid 1 and the body 2 together. The longitudinal telescopic rod 42 is located in the telescopic rod cavity 52 and the longitudinal telescopic rod 42 is engaged with the end opening of the telescopic rod cavity 52. ​​The base plate 5 is attached to the bottom plate of the body 2 and fixed with screws. The bottom plate of the body 2 closes the upper opening of the accommodating cavity 51. When in use, the support rod 7 is detachably connected to the support rod hole 53. When stored or moved, the support rod 7 is embedded in the support cavity 61. The movable cover 6 is engaged with the lower opening of the accommodating cavity 51 and is detachable. The support cavity 61 and the bottom plate of the body 2 fix the support rod 7.

[0051] The width of the support cavity 61 is smaller than the diameter of the support rod 7, and the depth of the support cavity 61 is less than or equal to the radius of the support rod 7. This design facilitates the placement and removal of the support rod.

[0052] As a further improvement of the present invention: the base plate 5 is provided with positioning grooves 54 on both sides in the width direction;

[0053] The bottom plate of the box 2 is provided with two positioning blocks 21 along the width direction.

[0054] The positioning block 21 and the positioning groove 54 are engaged. This design prevents the base plate 5 from shifting relative to the housing 2.

[0055] As a further improvement of the present invention: the bottom plate of the box body 2 and the opposite part of the accommodating cavity 51 are provided with fixing plates 22, and the fixing plates 22 are provided with four arc-shaped slots;

[0056] The arc-shaped groove fits into the support rod 7 to prevent the support rod 7 from wobbling.

With this design, the support rod 7 provides a firm support and effectively prevents the box body 2 from shaking.

[0058] As a further improvement to the present invention: such as Figure 9 , Figure 10 As shown, the support rod hole 53 includes a slanted rod hole portion 531, a circular ring plate portion 532, an axial guide groove 533 provided on the circular ring plate portion 532, a stop block 534 on the upper end face, and an upper hole portion 535.

[0059] like Figure 11 As shown, the support rod 7 includes a rod body 71, a head 72, and a radial locking block 73 disposed on the head;

[0060] The rod body 71 is fitted into the inclined rod hole 531, and the end is supported by an annular plate 532. The radial locking block 73 is guided into the upper hole 535 through the axial guide groove, and the annular plate 532 is slidably engaged. The radial locking block 73 and the stop block 534 are engaged to stop the rod. This design not only makes disassembly and assembly convenient, but also prevents the support rod 7 from loosening.

[0061] As a further improvement to the present invention: such as Figure 1 , Figure 12 , Figure 14 As shown, the wall panel at one end of the accommodating cavity 51 is provided with a hinge groove 511, and the other end is provided with a hollow locking cavity 512 with openings at the top and bottom. A static hinge seat 5111 is provided in the middle of the hinge groove 511, and a locking rod 5121 is provided in the locking cavity 512.

[0062] One end of the movable cover 6 is provided with a hinge cavity 62 and a suspended cavity 63, and the other end is provided with two movable hinge seats 64. The suspended cavity 63 is located above the hinge cavity 62. The suspended cavity 63 is provided with stationary shaft seats 631 located on both sides of the hinge cavity 62. The wall plate of the suspended cavity 63 is provided with a torsion spring arm groove 632.

[0063] It also includes a fixed shaft 81, a torsion spring 82, and a movable locking element 83.

[0064] like Figure 14 As shown, the movable locking component 83 includes an operating plate 831, two movable shaft seats 832, a tongue arm 833 and a locking tongue 834 provided on the movable shaft seats; the tongue arm 833 is perpendicular to the operating plate 831, and the locking tongue 834 is perpendicular to the tongue arm 833; the tongue arm 833 between the two movable shaft seats 832 and the operating plate 821 form a torsion spring cavity;

[0065] The torsion spring 82 is located between the two movable shaft seats 832, the fixed shaft 81 passes through the movable shaft seat 832 and the torsion spring 82, and both ends of the fixed shaft 81 are fixed to the stationary shaft seat 631 in the suspended cavity. One torsion arm of the torsion spring 82 is engaged with the torsion spring arm groove 632, and the other end is attached to the operating plate 831. The operating plate 831 moves in the hinge cavity 632, the tongue arm 833 extends out of the suspended cavity 63, the tongue arm 833 extends into the locking seat, and the locking tongue 834 is engaged with the locking rod 5121. The stationary hinge seat 5111 is located between the two movable hinge seats 64 and is hinged together by a shaft.

[0066] As a further improvement of the present invention: one end of the movable cover 6 is provided with a handle 65, and the handle 65 is connected to one end of the hinge cavity 62; the base plate 5 is provided with a clearance cavity 56; the clearance cavity 56 is connected to the locking cavity 512, and the handle 65 corresponds to the clearance cavity 56.

[0067] like Figure 7As shown, in the closed and locked state, the movable cover 6 closes the lower opening of the accommodating cavity. When removing the movable cover 6, press the operating plate 831, and the movable locking member 83 rotates clockwise, causing the locking tongue 834 to disengage from the locking rod 5121. Since the operating plate 831 drives one end of the torsion spring 82, the torsion spring 82 stores force. After the hand leaves the operating plate 831, the movable locking member 83 automatically rotates counterclockwise and resets. Then, drive the handle 65 by hand, and the movable cover 6 rotates clockwise, opening the accommodating cavity 51. The support rod 7 can be removed and placed from the movable cover 6.

[0068] During assembly, the movable cover 6 rotates in the opposite direction, and the locking tongue 834 enters the locking seat 513. The locking tongue 834 and the locking rod 5121 slide together, and the torsion spring stores force. After the locking tongue slides past the locking rod 5121, under the action of the torsion spring, the locking tongue 834 and the locking rod 5121 are engaged, and the assembly is completed.

[0069] As a further improvement of the present invention: the box cover 1 is provided with a hollow outer opening cover expansion groove 1A at both ends, and the cover expansion groove 1A is located on the top plate, front wall plate and rear wall plate of the box cover 1.

[0070] The front wall panel of the box 2 is provided with a front expansion groove 2A and the rear wall panel is provided with a rear expansion groove 2B.
