Problems solved by technology

[0003] Since the blade needs to overcome the friction force and the resistance of the steel ball when it is unfolded, it is generally necessary to use both hands to pull the nail (the nail is located on the blade) and the plate (the plate is located on the back of the blade) to unfold the blade, which is more convenient. laborious and inconvenient to use

Embodiment Construction

[0031] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0032] Such as Figure 1 to Figure 4 As shown, the quick opening folding knife of the present invention includes a handle 10 , a blade 20 , two ball assemblies 30 , an elastic arm 40 , a steel ball 50 and an opening mechanism 60 .

[0033] The handle 10 includes a first side piece 11 and a second side piece 12, and the first side piece 11 and the second side piece 12 surround a receiving groove 101;

[0034] One end of the blade 20 is pivotally connected to one end of the knife handle 10 through a rotating shaft and can be expanded and folded relative to the knife handle 10. The accommodating groove 101 is used to accommodate the blade 20 when the blade 20 is folded relative to the knife handle 10; The blade 20 is provided with a through hole 21 for inserting fingers. After the blade 20 is folded relative to the handle 10, the lower part of the through...

Abstract

The invention discloses a quick-opening folding knife. The quick-opening folding knife comprises a knife handle, a blade, two ball assemblies, an elastic arm, a steel ball and an opening mechanism. The knife handle comprises a first side sheet and a second side sheet, and a containing groove is defined by the first side sheet and the second side sheet. One end of the blade is connected to one end of the knife handle in a pivoted mode and can be folded and unfolded relative to the knife handle. The steel ball is installed on the side, close to the containing groove, of the first side sheet, and the steel ball is used for being matched with a concave portion in a clamped mode after the blade is folded relative to the knife handle. The opening mechanism comprises a movable piece, an installation base and the spring. The lower end of the installation base is provided with a first slope, the upper end of the movable piece is provided with a second slope, and the second slope is used for jacking the first slope when the movable piece moves upwards so that the installation based can move towards the side away from the containing groove. According to the quick-opening folding knife, a user can unfold the blade quickly by pulling a through hole in the blade with one hand.

Description

technical field [0001] The invention relates to a quick opening folding knife. Background technique [0002] Folding knives generally include a handle, a blade and a steel ball. The blade can be unfolded and folded relative to the handle. The steel ball is used to engage with the concave position of the blade when the blade is folded to prevent the blade from opening automatically. [0003] Since the blade needs to overcome the friction force and the resistance of the steel ball when it is unfolded, it is generally necessary to use both hands to pull the nail (the nail is located on the blade) and the plate (the plate is located on the back of the blade) to unfold the blade, which is more convenient. Laborious and inconvenient to use. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a quick-opening folding knife, which can quickly unfold the blade by pulling the through hole on th...
