The utility model discloses a foldable knife, which comprises a knife handle and a knife blade hinged between the front end of the knife handle. The end of the knife blade is provided with a connecting part, a switch installation hole is arranged on the knife handle above the right side of the installation hole and close to the location of the installation hole, a switch is installed in the installation hole, and a limited post is fixed between the knife handle above the installation hole, and a connecting part is arranged in front of the switch installation hole. A limited slot is arranged on one side of the end, and a groove is arranged on the upper end face of the connecting part. When the blade is fully opened, the bottom of the slot is offset by the limit column. The switch includes a variable diameter shaft, a pin and a dialer. The larger diameter end of the variable diameter shaft is adjacent to one end of the pin and the larger diameter end of the variable diameter shaft offsets the groove when the blade is fully opened. The utility model can clamp the connecting part in the groove of the connecting part by clamping the groove of the changing diameter axis of the switch on the limiting column at the same time after the blade is fully opened. When the blade needs to be closed, only one hand is needed to press one end of the changing diameter axis of the switch to move the smaller end of the changing diameter axis to the groove, because the changing diameter axis does not move to the groove at this time. In contact with the groove, the blade can be closed under its own gravity.
【技术实现步骤摘要】
一种可折叠刀
本技术涉及刀具结构
，特别是一种可折叠刀。
技术介绍
可折叠刀是一种刀具，指刀身能够自动弹出的刀。可折叠刀分为能缩回和不能缩回两种类型。原有的小刀轴锁结构在开刀的时候经常出现卡顿的现象，开刀不顺畅，使用不方便。
技术实现思路
本技术的目的是要解决现有技术中存在的不足，提供一种可折叠刀。为达到上述目的，本技术是按照以下技术方案实施的：一种可折叠刀，包括刀柄和铰连接在刀柄前端之间的刀片，所述刀片的末端设有连接部，所述刀柄末端内设有拨片，所述连接部中部开设有通孔，所述刀柄前端开设有用于安装转轴的安装孔，所述刀片的连接部末端放置于刀柄前端内且安装孔与通孔对应时通过转轴将刀片和刀柄连接，所述安装孔的右上方且靠近安装孔位置的刀柄上开设有开关安装孔，开关安装孔内安装有开关，开关安装孔前端且位于安装孔上方的刀柄之间固定有限位柱，所述连接部前端一侧开设有限位卡槽，连接部上端面开设有凹槽，限位卡槽底部在刀片完全打开时与限位柱相抵，所述开关包括变径轴、销钉和拨片，所述销钉一端固定在开关安装孔内，拨片固定在销钉另一端，变径轴一端位于刀柄外、另一端贯穿刀柄一侧的开关安装孔，...
