Fig. 1 to Fig. 4 is the structural schematic diagram of the present invention.
A kind of pressing expansion type ear-picking device, including shell 1 are from top to bottom disposed with hollow cylindrical in shell 1
Push rod 2, sliding pawl set 3, spring 4, the upper end of push rod 2 stretches out 1 upper port of shell, pressing, 1 upper end inner wall of shell is facilitated vertically to project
There are key rib 11, key rib 11 to be constituted by being equipped with the middle rib tenon 14 being slightly recessed between a left rib tenon 12, right rib tenon 13 and both sides of the chest tenon, respectively
The bottom of rib tenon is respectively provided with rib oblique 15, is equipped with a keyway 16 between adjacent key rib 11,2 lower end of push rod is provided with upper gnawing tooth 21, pushes away
2 lower end outer wall of bar is equidistantly equipped with key prominent 22, and key prominent 22 is corresponded to embedded at keyway 16 in middle rib tenon 14, and the key on push rod 2 is prominent
22 can slide in keyway 16 and middle rib tenon 14, to define that push rod 2 is only capable of vertical upper and lower displacement, the key lever on sliding pawl set 3
In 31 insertion push rods 2, keep sliding pawl set 3 more accurate with 2 concentricity of push rod, it is convex corresponding to being equipped at keyway 16 that sliding pawl covers 3 outer walls
Key 32,32 upper end of convex key are equipped with the inclined-plane being adapted to rib oblique 15, which is equally used cooperatively with upper gnawing tooth 21, under sliding pawl set 3
End face center is equipped with mounting hole 33, and 1 lower end of shell is connected with tube head 5, and 4 one end of spring is connected with tube head 5, the other end and cunning
Pawl covers 3 lower faces and is connected, and 1 lower end of shell is provided with earpick mechanism 6, and earpick mechanism 6 includes pillar 61 and main shaft 62, shield
61 lower end of pipe is set as breathing space 63, and breathing space 63 is vertically equipped with bar shaped fluting 64, and 62 lower end of main shaft is equipped with tapered protrusion 65,
Main shaft 62 places pillar 61, spring 4, is fixedly connected with the mounting hole 33 on sliding pawl set 3, tapered protrusion 65 is supported into breathing space 63
In bellmouth 66, principle that the present invention mainly uses：The anti-self-lock mechanism in inclined-plane, the fixed-axis rotation of grinding tooth, sliding block are along rail sliding, bullet
The conversion of spring energy, as shown in figure 4, a is that convex key 32 coordinates original state with key rib 11 in Fig. 4, the taper of main shaft 62 is convex at this time
65 bottoms for being in bellmouth 66 are played, breathing space 63 does not expand, at this time stretches into earpick mechanism 6 in external auditory canal, stretches into certain
After depth, push rod 2 is pressed down on, the upper gnawing tooth 21 of push rod 2 presses against the convex key 32 of sliding pawl set axially movable, critical until reaching
Point B, such as b in Fig. 4, the peak of convex key 32 is in contact with the minimum point of right rib tenon 13 at this time, under the recovery force effect of spring,
Rib oblique 15 opposite sliding of the upper gnawing tooth 21 along right rib tenon 13 is crossed on the inclined-plane of convex key 32, until convex key 32 slides into keyway 16,
Unde the action of the restoring force of the spring, push rod 2 and sliding pawl set 3 can be moved upwards along keyway 16, and sliding pawl set 3 can pull main shaft 62 upward
Mobile, breathing space 63 is strutted and is flared to and be bonded with external auditory canal by tapered protrusion 65, when key is dashed forward 22 upper ends and 16 upper end of keyway
Stop movement after offseting, such as c in Fig. 4, pulls out earpick mechanism 6 and can will be attached to earwaxing on external auditory canal and take out of, earpick machine
Structure 6 presses down on push rod 2 again after being taken out in external auditory canal, and the upper gnawing tooth 21 of push rod 2 presses against the convex key 32 of sliding pawl set in an axial direction
Movement, until reaching critical point A, such as d in Fig. 4, the peak of convex key 32 is in contact with the minimum point of left rib tenon 12 at this time, in bullet
Under the recovery force effect of spring, rib oblique 15 opposite sliding of the upper gnawing tooth 21 along left rib tenon 12 is crossed on the inclined-plane of convex key 32, is fallen therewith
Enter in the groove of middle rib tenon 14 and right rib tenon 13 and stop sliding, the tapered protrusion 65 of main shaft 62 retreats to the most lower of bellmouth 66
End, breathing space 63 is used because natural resiliency from softened state is become being closed convenient for next time, simple in structure, safe, will not will
Depths is pushed in earwaxing for external auditory canal side mouthful to, and cleaning effect is good.
In embodiment, the number of bar shaped fluting 64 is four, and four bar shaped flutings 64 are pair with the axis of pillar 61
Axis is claimed to be distributed at axial symmetry, the angle between adjacent bar fluting 64 is 90 °, the expansion of more convenient breathing space 63.
In embodiment, 61 lower end of pillar is provided with the soft convex ribs 67 of a circle, plays the role of scraping to external auditory canal, will earwax
Scraping is got off, while soft convex ribs will not injure skin of external auditory canal.
In embodiment, pillar 61 is made of soft rubber, and there is certain flexibility and elasticity will not injure external ear simultaneously
Road skin.
