Labor-saving binder clip

Abstract

The invention relates to an effort-saving binder clip. The effort-saving binder clip comprises a clamping part, a rear part, a rod component which is made of a rod, when the binder clip is used, a first rod component passes through a first hole, the first rod component abuts against one end, located on the opening side of an A part, of the first clamping part, a first fulcrum is formed through abutting, a gap is formed on a portion, located in a region between the first fulcrum and a pivoting part, of the first rod component and the first clamping part, when the binder clip is used, a second rod component penetrates through a second hole, the second rod component abuts against the end, located on the opening side of a C part, of a second clamping part, a second fulcrum is formed through abutting, and a gap exists in the portion, located in a region between the second fulcrum and the pivoting part, of the second rod component and the second clamping part. The labor-saving purpose can be achieved without additionally providing protruding fulcrums on the clamping part or the rod components, and production and machining can be greatly simplified while the labor-saving purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of long tail clips, in particular to a labor-saving long tail clip. Background technique [0002] The long tail clip is a kind of clip that is widely used in daily office or life. The structure usually includes a clamping part, a rear part, and a rod member made of a rod. There are two clamping parts, and the rear part is located at one end of the clamping part. The two clamping parts are connected, and the two clamping parts form an openable opening at the other end, and the other end of each clamping part is provided with a pivoting part. Corresponding settings, for the convenience of description, the two clamping parts and the two rod members can be respectively referred to as the first clamping part, the second clamping part, the first rod member, and the second rod member. When the long tail clip is used One end of the first rod member and one end of the second rod member both exceed the rear part, and...

AI Technical Summary

Problems solved by technology

The long tail clip roughly has the above structure. It can be seen that the structure is very simple, there are few parts, and there is very little room for structural adjustment. It becomes very difficult to adjust the structure or further improve the structure.

[0003] In order to achieve the purpose of labor saving, the usual practice in the prior art is to set a fulcrum between the clamping part and the rod member. By setting the fulcrum, the power arm is long and the resistance arm is short, but it is necessary to additionally set a protrusion on the clamping part or the rod member. The fulcrum increases the complexity of production and processing. This type of structure is such as the Japanese invention patent JP3117841U that has been published for a long time. -09-15, however, until now, this technology is still continued in the industry, without a fundamental breakthrough, such as the recently published Chinese invention patent application CN109228731A, Chinese invention patent CN208263788U, etc., it can be seen that the labor-saving design in the industry The status quo of the current state of mind has been fixed, and there is no further breakthrough
