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.

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.

The present invention discloses a folding knife, which belongs to the field of manual cutting tools. Conventional folding knives suffer from the drawbacks of cumbersome operation of the locking mechanism for preventing accidental folding, and potential safety hazards as fingers are located in the folding path of the blade during folding. In the present invention, a finger control part protrudes from a side surface of a front end of a handle part for a finger to apply an unlocking force rearward. The handle part is provided with a forward force application contour feature. A distance between the finger control part and the forward force application contour feature is adapted to allow that fingers of a single hand are able to manipulate the finger control part as the same hand grips and controls the forward force application contour feature, and the hand applies a forward control force to the forward force application contour feature as the fingers apply the unlocking force rearward to the finger control part. Therefore, by gripping the forward force application contour feature with one hand and using a finger of the same hand to apply the unlocking force rearward to the finger control part, the hand is caused to apply the forward control force to the forward force application contour feature. The opposing directions of the unlocking force and the control force cause the handle part to be squeezed and controlled in the hand, thereby allowing the fingers to avoid the folding path and then perform the operation of folding or unfolding the folding part.

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.
