Description
Technical field
The present invention relates to portable cutting device technical field.
Background technology
At present; in some nature, non-natural disasters; the emergency such as often occur the human body protection, Ore or some the hard steel cards that are collapsed main, wherein great majority be certain position of human body by hard objects card master, such as armored concrete, clump, iron and steel shell, Ore etc..At present for the rescue of this type of disaster to use cutting tool.Although and this type of instrument has reasonable cutting effect for hard thing, but all there is shortcoming: when close to human body, saw blade significantly moves back and forth and can hurt human body, causes secondary injury.And take additive method to replace cutting tool, and inefficient, it is possible to lead to miss best rescue time, aggravate disaster affected people traumatic condition, even cause more serious casualty accident.
Utility model content
The technical problem to be solved, it it is the technical deficiency for above-mentioned existence, a kind of frequency low-amplitude rescue saw is provided, human body is encountered when cutting hard thing, can do the reciprocating motion of frequency low-amplitude, and the skin of human body is stretched in suitable scope and not damaged, the effect of " cut firmly protect soft " thus reach, achieve rescue saw human body not to be damaged when cutting object, to ensure the safety of disaster affected people in rescue operations.
The technical solution used in the present invention is: provide a kind of frequency low-amplitude rescue saw, including actuator, actuating unit, shell；Described actuator includes two saw blades be arrangeding in parallel；Each saw blade is connected with the slide on shell by the slide block of sidewall；The fixing end of two saw blades is rotationally connected with the effort end of a lever plate respectively；The both ends supporting axle and the shell of each lever plate are rotationally connected；The laborsaving end of each lever plate is rotationally connected respectively through the both ends of connecting plate and a seesaw；Rotating shaft two ends in the middle part of described seesaw and shell are rotationally connected；Described actuating unit includes drive motor and coaxial eccentric；Described drive motor and shell are fixed；Described eccentric eccentric shaft and seesaw end are rotationally connected with the two ends of an arm-tie respectively.
Different from traditional rescue cast-cutting saw significantly cutting mode, the saw blade that frequency low-amplitude rescue saw two directions of motion of employing are contrary does the reciprocating motion of frequency low-amplitude, utilize the pliability feature than human body skin pliability difference of hard objects, frequency low-amplitude moves back and forth only can stretched skin within the specific limits, make skin and saw blade resonance, do not result in damage；Hard objects contacts with the saw blade of frequency low-amplitude, can be cut into fine particle, thus reaching the purpose of protection disaster affected people.
Optimizing the technical program further, the sawtooth of two saw blades of frequency low-amplitude rescue saw is in opposite direction.
Object is applied the reverse cut power that an equity is big by double; two saw blades, it is possible to the cutting force retroaction to saw body when preventing from cutting, and makes hand-held more stable, and can improve cutting efficiency.
Optimize the technical program further, each lever plate of frequency low-amplitude rescue saw is equipped with the spacing groove supporting axle；Described support axle both ends and lever plate are fastened by nut.
Change and support axle position in spacing groove, it is possible to regulate the length of two arm of forces of lever plate, such that it is able to change the motion amplitude of saw blade.Can determine that below hard objects when no signs of life, it is possible to by increasing the motion amplitude of saw blade, improve cutting efficiency.
Optimizing the technical program further, the shell of frequency low-amplitude rescue saw is fixed with saw holder, described saw holder includes the loop-shaped handle being fixed on outer casing top surface and " q " the shape handle being fixed on the shell side relative with saw blade.
The invention has the beneficial effects as follows: use frequency low-amplitude rescue saw, human body is encountered when cutting hard thing, saw blade can do the reciprocating motion of frequency low-amplitude, and the skin of human body is stretched in suitable scope and not damaged, the effect of " cut firmly protect soft " thus reach, achieve rescue saw human body not to be damaged when cutting object, to ensure the safety of disaster affected people in rescue operations；In the process of cutting, saw body is stable, and also can change cutting efficiency by adjustment saw blade reciprocation amplitude, to adapt to different rescue environment.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Shown in Fig. 1, Fig. 2, frequency low-amplitude rescue saw includes actuator, actuating unit, shell 7；Actuator includes two saw blades be arrangeding in parallel 1；Each saw blade 1 is slidably connected with the chute 3 on shell 7 by the slide block 2 of sidewall；The fixing end of two saw blades 1 is rotationally connected with the effort end 5 of a lever plate 4 respectively；The both ends supporting axle 6 and the shell 7 of each lever plate 4 are rotationally connected；The laborsaving end 8 of each lever plate 4 is rotationally connected respectively through the both ends of connecting plate 9 and a seesaw 10；Rotating shaft 11 two ends in the middle part of seesaw 10 and shell 7 are rotationally connected；Actuating unit includes drive motor 12 and coaxial eccentric 13；Drive motor 12 is fixed with shell 7；Eccentric shaft 14 and seesaw 10 end of described eccentric 13 are rotationally connected with the two ends of an arm-tie 15 respectively；The sawtooth 16 of two saw blades 1 of frequency low-amplitude rescue saw is in opposite direction；Each lever plate 4 of frequency low-amplitude rescue saw is equipped with the spacing groove 17 supporting axle 6；Support axle 6 both ends to be fastened by nut 18 with lever plate 4；Being fixed with saw holder on shell 7, saw holder includes the loop-shaped handle 19 being fixed on shell 7 end face and " q " the shape handle 20 being fixed on shell 7 side relative with saw blade 1.
When drive motor 12 starts, eccentric shaft 14 and arm-tie 15 link, and drive seesaw 10 reciprocally swinging, it is possible to the rotating speed regulating drive motor 12 as required controls the frequency that seesaw 10 swings.Seesaw 10 swings, and drives the connecting plate 9 at two ends, thus driving two lever plates 4 to do reciprocally swinging in opposite direction, two saw blades 1 do reciprocating motion in opposite direction.
Panasonic supports the nut 18 at axle 6 two ends, moves supporting axle 6 to the effort end 5 of lever plate 5, it is possible to reduce the reciprocating amplitude of saw blade 1；Move supporting axle 6 to the laborsaving end 8 of lever plate 5, it is possible to increase the reciprocating amplitude of saw blade 1；By adjusting the reciprocating amplitude of saw blade 1, the cutting efficiency of saw blade 1 can be changed, when it should be noted that the side supporting axle 6 close laborsaving end spacing groove 17 in, the reciprocating amplitude of saw blade 1 is the amplitude peak that the pliability of human body skin can bear.
When using frequency low-amplitude rescue saw, two handss of user grip loop-shaped handle 19 and " q " handle 20 respectively, the resistance rotary switch 21 controlling drive motor 12 may be mounted on loop-shaped handle 19, user can control resistance rotary switch 21 according to rescue environment, thus controlling the rotating speed of drive motor 12, improving or reducing cutting efficiency.
