Embodiment Construction

[0030] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0031] see Figure 1-Figure 2 , shows a kind of trigger 5 knife of a preferred embodiment of the present invention, and this trigger 5 knife comprises knife body 1, knife rest 2, blade 3, elastic member, trigger 5, transmission mechanism and block 81, wherein, knife rest 2. The blade 3, the elastic member and the transmission mechanism are all located in the inner cavity of the blade body 1, and the blade holder 2 is slidably connected with the blade body 1, so that the blade 3 can extend out of the blade body 1 along the first notch 15 of the blade body 1 or retract. Back in the knife body 1, the blade 3 is connected with the knife holder 2, the elas...

Abstract

The invention discloses a trigger knife. The trigger knife includes a knife body, a knife holder, a blade, an elastic member, a trigger, a transmission mechanism and a block. The knife holder and the knife body are slidably connected, the blade is connected to the knife holder, and the elastic member is used for The blade provides an elastic force to be retracted into the inner chamber of the knife body, and the trigger is rotatably arranged on the knife body, so that the trigger can move in the knife body, and its part is exposed to the knife body. The transmission mechanism includes a first rack, a first gear, a second Two gears and a second rack, the first gear and the second gear are pivotally connected with the knife body, the central axis of the rotating shaft is perpendicular to the sliding direction of the tool holder, the first rack is arranged on the trigger and meshes with the first gear, and the second gear is engaged with the first gear. The second rack is arranged on the tool holder and meshes with the second gear, and the extension direction of the second rack is the same as the sliding direction of the tool holder; the tool holder is provided with a groove, and the extension direction of the groove is the same as the extension direction of the tool holder. When the blade is extended into place, the stop abuts against the wall of the groove. The trigger knife is easy to cut and has a longer distance.

Description

technical field [0001] The invention relates to the technical field of hand-held safety knives, in particular to a trigger knife. Background technique [0002] The trigger knife is a kind of knife among hand-held safety knives. Its blade can be retracted into the knife body, and its blade can extend out of the knife body when in use, thus improving the safety of the trigger knife. [0003] For example, a safety cutting knife disclosed by the patent application number CN201010230575.4 specifically includes a housing, a detachable blade protective sleeve placed at the end of the housing, and a blade fixedly connected to the rotating knife rest. The two ends of the tension spring are respectively connected to the housing and the slider, and the two ends of the tension spring are respectively connected to the housing and the sliding knife holder. One end of the trigger is connected to the housing through the fulcrum E, and the other end of the trigger can move up and down around...
