Description

Technical Field

[0001] The utility model relates to the technical field of dovetail clamps, in particular to a hollow dovetail clamp. Background Art

[0002] Dovetail clips are a commonly used type of stationery, mainly used to collect a stack of documents together. Dovetail clips are widely loved by people because they are easy to disassemble, recyclable, environmentally friendly and durable.

[0003] Regarding the existing patent number: CN201921447477.9, the patent name is: a hollow dovetail clip, which adopts an elastic clip main body that is set, and the two pressing handles are both rod-shaped curved structures, and are both formed in one piece by bending steel wire. It has a high non-obstruction rate, which greatly reduces the obstruction of the text or title on the document by the hollow dovetail clip, which is beneficial to document identification. However, when storing, multiple dovetail clips cannot be fixed to each other. When storing, the dovetail clips are easily dispersed, resulting in a larger occupied space, resulting in a reduction in the number that can be stored.

[0004] When the existing dovetail clips are stored, multiple dovetail clips cannot be fixed to each other. When stored, the dovetail clips are easily dispersed, resulting in a larger occupied space and a reduced number of dovetail clips that can be stored. Therefore, it does not meet the existing needs. In this regard, we propose a hollow dovetail clip. Utility Model Content
