The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Refer to Fig. 1 to Fig. 3, a kind of safety diving cutter 100 of the utility model, comprise blade 10 and be fixed on the double-edged razor blade 20 on blade 10, these double-edged razor blade 20 one sides have linear pattern blade 21, another side has sawtooth pattern blade 22, described blade 10 is also provided with a secure shroud 30 and a movable shield 40, these secure shroud 30 stationary shroud are in linear pattern blade 21 1 sides, this movable shield 40 be articulated in opening or closing on blade 10 and shade in sawtooth pattern blade 22 1 sides, between secure shroud 30 and linear pattern blade 21 and between movable shield 40 and sawtooth pattern blade 22, be reserved with cutting room 50.
Described blade 10 comprises front blade 11 and the rear blade 12 being divided into two, and this forward and backward blade 11,12 includes annular grip part 110, blade installation slot 111 and from blade, 111 grooves is installed and to the same side, given prominence to the extension forward and backward secure shroud 112,113 that then roundabout bending is extended; This annular grip part 110 facilitates diver to carry and grips in use; Described forward and backward secure shroud 112 all has circular connecting portion 1121 and long handle shape cover body 1122, and the junction of described connecting portion 1121 and blade installation slot 111 convexes with lock part 1123; Particularly, described annular grip part 110 is provided with installing hole 1124 with the junction of blade installation slot 111, and blade installation slot 111 is also provided with pivoted hole 1125 with secure shroud 30 junctions.
Described movable shield 40 comprises front movable shield 41 and rear movable shield 42, the lever arm 44 that forward and backward movable shield 41,42 all has circular pivot portion 43 and extended by pivot part 43, this lever arm 44 is provided with pivot part 43 junctions the snapclose sheet 45 matching with the lock part 1123 of blade 10.
Particularly, described double-edged razor blade 20 lower ends are provided with fixing hole 23; Preferably, described double-edged razor blade 20 is to form with high strength titanium alloy or zirconia ceramics manufacture, can resist invading Erosion and can not getting rusty of seawater, has avoided the trouble of the maintenance work that the cutter of steel blade must carry out after each diving.
