Embodiment

Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.

Shown in Fig. 1-3, a kind of ratchet-type cable cutter comprises the first in command 2 and the second in command 3 that flexibly connect through axis 1; The end that the said first in command's 2 end is provided with first blade, 4, the first blades 4 is provided with blade 7 through the inboard that rotating shaft 5 flexibly connects second blade, 6, the second blades 6 and first blade 4; The root that the outer ledge of second blade 6 is provided with master gear 8, the first blades 4 is provided with on first screw mandrel, 9, the first screw mandrels 9 and is with torsion spring 10; The right side of first screw mandrel 9 is provided with second screw mandrel 11; Second screw mandrel 11 is provided with switch latch 12, and an end of torsion spring 10 is stuck on first blade 4, and an other end of torsion spring 10 is connected on the switch latch 12; First blade 4 of second screw mandrel, 11 tops is provided with the 3rd screw mandrel 13; The second in command 3 who is connected first spring, 14, the three screw mandrels, 13 left sides between the 3rd screw mandrel 13 and the second in command 3 is provided with switch hole clipping 15, and the right side near axis 1 on the second in command 3 is provided with pinion 16; The outside of pinion 16 is resisted against on the master gear 8; Second spring 17 is set between the pinion 16 and the second in command 3, and the end of said first screw mandrel 9, second screw mandrel 11 and the 3rd screw mandrel 13 is protecting cover 18 fixedly, and protecting cover 18 is provided with and the corresponding grip switches 19 in switch hole clipping 15 positions.

The ratchet-type cable cutter of the utility model is covered with plastic casing on the said first in command 2 and the second in command's 3 the outer wall.

The ratchet-type cable cutter of the utility model; Said grip switches 19 comprises metal shell 20; Metal shell 20 bottoms are provided with drain pan 21; The inside of metal shell 20 is provided with the metal shaft 22 that matches with switch hole clipping 15, and the end of metal shaft 22 is provided with metal button 23, is with the 3rd spring 24 on the outer wall of metal shaft 22.

The ratchet-type cable cutter of the utility model is when concrete the use, and pull switch latch 12 is outwards released second blade 6, is stuck on the cable; Promote second blade 6 master gear 8 is contacted with pinion 16, through the operation first in command 2 and the second in command 3, the motion of pinion 16 just can drive the motion of master gear 8; Play first violin 2 with the second in command 3 when loosening, under the effect of first spring 14, outwards move the second in command 3; Pinion 16 playback, when holding handle once more with a firm grip, second spring 17 upwards promotes pinion 16; Pinion 16 is just combined closely with master gear 8, and drive master gear 8 moves together, like this back and forth movement through not stopping back and forth; The motion that second blade 6 does not stop under master gear 8 drives, the space between first blade 4 and second blade 6 is more and more littler, until cutting off cable.Pinion 16 keeps dynamic fit with switch latch 12, and after the second in command 3 coincide toward the first in command 2, switch latch 12 promoted toward the top then; The second in command 3 slowly unclamps earlier with the first in command 2 then, and the wedge angle of switch latch 12 leans on the radian edge of the second in command 3 upper ends, when sliding into the wedge angle of pinion 16; Force pinion 16 fully to separate with master gear 8; Prevent the inordinate wear of master gear 8 and pinion 16 no effects, guarantee fully that secondly end user easily rotates master gear 8 blades, is set in necessarily required shearing scope arbitrarily; Pull the first in command 2 and the second in command 3 then; Through torsion spring 10 and second spring, 17 flexible principles, force automatically reseting of switch latch 12 and pinion 16, pinion 16 will recover the shearing work state automatically with master gear 8 blades.Ragged edge at cable cutter also has protecting cover 18, and protecting cover 18 is fixing through first screw mandrel 9, second screw mandrel 11 and the 3rd screw mandrel 13 on first blade 4, on protecting cover 18; Grip switches 19 is installed, on the second in command 3, is provided with switch hole clipping 15, when the two grip merging of scissors; Press metal button 23, metal button 23 can promote metal shaft 22 and move downward, and metal shaft 22 just is stuck in switch hole clipping 15 the insides on the second in command 3; Scissors just can be in closed condition like this, is convenient for carrying.When just reusing the first in command 2 is moved with 3 liang of handles of the second in command a little, metal button 23 will withdraw from automatically and open the scissors handle, use this product.

The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection range of the utility model.
