Folding saw capable of being opened automatically

Abstract

The invention discloses a folding saw capable of being opened automatically, which comprises a handle and at least one saw blade folded in the handle by rotation, and an elastic clamping mechanism for clamping the free rotation of the saw blade and an ejection mechanism for providing automatic ejection power for the saw blade are arranged at connecting end parts of the handle and the saw blade. Compared with the prior art, the folding saw has the following benefits: 1) the folding saw has compact and reasonable overall structure, easy manufacture and convenient operation; and 2) the folding saw can be operated by single handle, be opened automatically, realize high safety, prevent the automatic folding back due to the action of external force, avoid damages and be further conductive to popularization in a plurality of fields.

Description

technical field [0001] The invention relates to a folding saw, which belongs to the technical field of sawtooth tools, in particular to a folding saw that can be opened automatically. Background technique [0002] At present, in many industries, such as interior decoration, carpentry or gardening, etc., it is often necessary to use a portable saw in the work process, especially a portable folder. In the prior art, the folding document generally includes a handle and a saw blade that is folded in the handle. When in use, grasp the handle and the saw blade with both hands to open the saw blade to the outside. Although the folding document of this structure is simple in structure, However, it cannot be operated with one hand when it is opened, which sometimes causes inconvenience during actual operation. Therefore, the relevant industry has developed and produced a type of folding saw that can be automatically opened, and the purpose of opening the saw blade with one hand is r...

Problems solved by technology

In the prior art, the folding document generally includes a handle and a saw blade that is folded in the handle. When in use, grasp the handle and the saw blade with both hands to open the saw blade to the outside. Although the folding document of this structure is simple in structure, However, it cannot be operated with one hand when it is opened, which sometimes causes inconvenience during actual operation

Therefore, the relevant industry has developed and produced a type of folding saw that can be automatically opened, and the purpose of opening the saw blade with one hand is realized by setting an automatic opening device, so as to facilitate actual use and operation. However, there are some folding saws that can be automatically opened at present. Defects, such as the possibility of injury due to excessive elastic force when the saw blade pops out, or the saw blade is easily turned and folded back under force during use, causing damage, etc. Therefore, the safety of use is not high enough and needs to be improved
