Abstract: A folding knife, comprising: a handle; a blade assembly pivotably connected to one end of the handle, the blade assembly being configured to be rotatable relative to the handle; a locking mechanism configured to be engageable with the blade assembly, wherein the folding knife is configured such that: the blade assembly has at least two states, the blade assembly is switched between different states by rotating, the locking mechanism, when engaged with the blade assembly, locks the blade assembly in a current state, and the locking mechanism, when disengaged from the blade assembly, is able to unlock the blade assembly.

Abstract: A storage box is provided. The storage box includes two first side walls, a second side wall and a bottom wall. The two first side walls are connected to two sides of the second side wall, respectively; and the two first side walls are opposite to each other. The second side wall and the two first side walls are fixedly connected to the bottom wall, respectively; and the bottom wall, the second side wall and the two first side walls are enclosed together to form a first accommodation space.

Abstract: A package arrangement includes a support board. The support board is formed of at least two layers of plate laminated and affixed together. Adjacent two plates of the at least two layers of plate define therebetween a cavity for receiving at least part of a hand tool. Each plate of the at least two layers of plate is fabricated from a material satisfying recycling requirements for the same class of materials.

Abstract: A stacking system is provided. The stacking system includes a first stacking device and a second stacking device being arranged in a stacked configuration. The first stacking device is provided with a first fitting structure, the second stacking device is provided with a second fitting structure, the first fitting structure and the second fitting structure have a locked state and a released state. In the locked state, the first fitting structure and the second fitting structure are locked to connect the first stacking device and the second stacking device. In the released state, the first fitting structure and the second fitting structure are released from each other.

Abstract: The present disclosure provides a storage system, which includes a chassis, a supporting frame and at least one intermediate plate movably connected to the supporting frame. The supporting frame includes a first folding mechanism connected to the chassis and a second folding mechanism. The intermediate plate is capable of rotating along with the first folding mechanism and/or the second folding mechanism. The first folding mechanism and the second folding mechanism can move close to the chassis through a space, so that the storage system is switched to the folded state.

Abstract: A glue gun, including: a main body, one end of the main body formed as an accommodation part for accommodating a glue cylinder; a first handle and a second handle, the first handle coupled to the second handle by a pivot pin shaft, one of the first handle and the second handle configured as a fixed handle, the other configured as a movable handle pivotable relative to the fixed handle, the fixed handle coupled to the other end of the main body, wherein the movable handle is provided with an actuating member, the actuating member configured to push a push member of the glue gun; at least one of the actuating member and the pivot pin shaft is configured to be adjustable in position to vary a distance between the actuating member and the pivot pin shaft, resulting in a switching between at least two gear positions.

Abstract: A cutting tool includes a bearing member, a first cutting member, a second cutting member, a manipulation member, an avoidance part and a measuring member. The first cutting member is fixedly disposed on one side of the bearing member. The second cutting member is pivotable about a first axle provided on the bearing member, and the manipulation member is pivotable about a second axle provided on the bearing member. The manipulation member and the second cutting member make up an effort-saving lever, in which the manipulation member drives the second cutting member to move. The cutting tool may further include a handle. The handle is configured to be insertable into and positionable at an end of the manipulation member away from the second axle.

Abstract: A shelving apparatus includes a shelving member, horizontal support members, vertical support members and structural support members. The shelving member is able to store items. The horizontal support members are configured to support the shelving member. The horizontal support members include first horizontal beams and second horizontal beams, which are arranged in opposition horizontally. The vertical support members are configured to be able to support the first horizontal beams and the second horizontal beams. The vertical support members include first vertical posts and second vertical posts, which are arranged in opposition horizontally. The structural support members include vertical-post bracing struts provided between the first vertical posts and the second vertical posts. One end of the vertical-post bracing struts is provided with locating mechanisms.

Abstract: A ratchet mechanism includes: a first member having an annular surface provided with a plurality of teeth arranged parallel to its axial direction; a second member configured to be rotatable relative to a circumferential direction of the annular surface; at least two first drive transmission members arranged on the second member, each including at least one ratchet tooth, the first drive transmission members being configured to be engaged with the teeth to transmit motion between the first member and the second member, where the ratchet tooth of each of the first drive transmission members is in different engaged states with the teeth.
