The present invention specific work process be：In original state, the arc scraping blade 6 positioned at both sides is in the present apparatus simultaneously Centre position, and realize that the initial position of the arc scraping blade 6 of both sides is located on the same line, the at this time lower end of two connecting rods 7 To central reduction, tension spring 8 is in unstretched condition.

When using the present apparatus, first determine whether which kind of skin disease patient belongs to, it is different according to different skin disease settings Pressure value sets different pressure values to meet different patients, realize it is different it is clear scrape depth, pressure is realized under the action of air pump 28 Pressure increase in power case 2 can push piston 4 to be moved downward in sleeve 3 after the pressure increase in forbay 2, and at this In a motion process, moving downward for piston 4 drives strut 5 to be moved downward along straight slot 27, and moving downward for strut 5 can make The fixed arc scraping blade 6 in 5 one end of strut move downward, arc scraping blade 6 moves downward the lower end in contact that can cause arc scraping blade 6 Skin, when arc scraping blade 6 contacts skin, meeting driving device integrally moves upwards, and presses down on frame 17 with hand at this time, frame 17 stress of frame moves downward, and moving downward for frame 17 can drive supporting leg 20 to move downward, and this motion process can cause supporting leg 20 are pressed down against compression spring 22, and compression spring 22 is shunk, and the fixation of pressurization its underpart is realized during compression spring 22 is shunk Rubber pad 21 so that rubber pad 21 is fitted closely with skin, and during frame 17 is pressed down against, due to skin phase The arc scraping blade 6 of contact can be driven arc scraping blade 6 to transport upwards by the resistance from skin under the action of this resistance It is dynamic, so as to the pressure that forbay 2 is overcome to be provided, and during this compression skin overcomes the pressure in forbay 2, meeting Realize that arc scraping blade 6 drives strut 5 to move upwards, and moving upwards for strut 5 can be moved upwards with piston 4 in sleeve 3, And moving upwards for piston 4, it can cause piston 4, sleeve 3, increase with the pressure in one airtight cavity of composition of forbay 2, and This increase process can cause the power for compressing skin downwards also to increase, the depth being cut into so as to fulfill arc scraping blade 6 in skin Variation, from the requirement that with people's satisfaction different patients are scraped clearly with different depth cutaneous lesions region.

When cut skin arc scraping blade 6 reach preset depth after, open simultaneously at this time stepper motor 10 with not The driving motor of complete gear 16, and the requirement of the rotating speed of this two motors is that the rotating speed of driving motor will be far longer than stepping The rotating speed of motor 10 after preferred stepper motor 10 rotates, can realize that stepper motor 10 drives roller 9 to rotate, and the rotation of roller 9 It can drive and realize that the first rope 11 is slowly wound on roller, so as to fulfill the tightening of the first rope 11, and in 9 turns of this roller During dynamic realization the first rope 11 tightening, two hinged connecting rods 7 can be downward under the action of the first rope 11 Movement, during at this, even 7 articulated position of connecting rod is stretched downwards under the action of the first rope 11, two inclined connecting rods 7 have the tendency that being drawn as horizontal, and this motion process can then realize that connecting rod 7 pushes the supporting rod 1 hinged with it outward, branch Strut 1 moves under the action of connecting rod 7 to both sides.

First sliding block 18 at 1 both ends of supporting rod can be realized corresponding during supporting rod 1 is moved to both sides The Slideslip from inside to outside of the first sliding groove 19, and this motion process can then realize that the fixed forbay 2 of institute is outside on each supporting rod 1 Side is moved, so as to which institute fixed sleeve 3, piston 4 and arc scraping blade 6 on forbay 2 be driven to move outward, so as to fulfill right The clear of lesion region skin is scraped.

And in this motion process, since the driving motor on partial gear 16 realizes rotation simultaneously, motor turns It is dynamic that its output shaft can be driven to rotate, partial gear 16 is driven to rotate through transmission shaft, partial gear 16 during rotation, When the toothed portion of partial gear 16 starts to have contacted the gear 15 of lower section, the rotation of partial gear 16 can nibble Merging zone method Moving gear 15 rotates, and the rotation warp beam of this wheel drives reel 13 to rotate, and the rotation of reel 13 can realize that the second rope 14 exists The tightening of the second rope is wound and realized thereon, and can then realize that the second rope 14 pulls downward on lantern ring during this tightening 12, moving downward for lantern ring 12 can drive roller 9 to move downward, due to lantern ring 12 be sleeved on roller 9 therefore in lantern ring 12 have no effect on roller 9 rotation of itself while driving roller 9 downwards, and roller 9 is realized during roller 9 moves downward The first rope 11 is driven to move downward, and the connecting rod 7 for driving two upper ends hinged under the action of the first rope 11 moves downward, And cause connecting rod 7 that 1 time more lateral of supporting rod is pushed quickly to move, the stretching of tension spring 8 can be realized in this motion process, and make The trend and elastic potential energy of 8 existing rebound of tension spring.

After the toothless part of partial gear 16 is turned to 15 corresponding position of gear, due on partial gear 16 Tooth be no longer able to engagement and drive gear 15, at this time gear 15 be no longer influenced by the driving force from partial gear 16, therefore Realize that the hinged strut 5 in two upper ends, to middle shrinkage, is shunk under the action of tension spring 8 at this under 8 rebound effect of tension spring Motion process in, two supporting rods 1 are to intermediary movements and forbay 2 and arc scraping blade 6 fixed thereon is driven to be leaned on to centre Hold together, and during this draws close to centre, the blade of arc scraping blade 6 no longer travels forward, therefore this process will not be made The secondary injury of pairs of patient skin.

During two supporting rods 1 are to intermediary movements, the articulated position of two struts 5 can be caused to move upwards, and This, which is moved upwards, to drive, and the first rope 11 is pulled up, and the first rope can be realized during the first rope 11 stretches 11 drive rollers 9 move upwards, and moving upwards for roller 9 can be so that be placed in the rectangular shaped slider 23 of 9 both sides of roller in sliding rail 24 It moves up and down, and stepper motor 10 continues the first rope 11 of tightening of driving roller 9 during this, when the mistake that roller 9 moves upwards Cheng Zhonghui drives lantern ring 12 to move upwards, and moving upwards for lantern ring 12, the second rope 14 can be driven to move upwards, at this In motion process, the second rope 14 is stretched by lantern ring 12 so that the second rope 14 being wrapped on reel 13 drives reel 13 rotate backward, and since reel 13 and gear 15 are co-axially mounted, the rotation of reel 13 can realize the reset of gear 15.

After the skin of completion side is scraped clearly, the present apparatus is rotated so that the arc scraping blade 6 of both sides scrapes the skin of respective side, So as to fulfill to entire diseased region and clear scrape.

The present apparatus, which compares traditional skin scraper, following benefit：

1st, the present apparatus provides the preset pressure value set by an air pump 28 for forbay 2 so that the present apparatus is in clear rossing It moves downward piston 4 before skin under the action of atmospheric pressure first, and causes the arc scraping blade 6 ined succession on piston 4 and skin phase Place is met, meeting after arc scraping blade 6 touches skin, skin can provide a reaction force, and this reaction to arc scraping blade 6 Power can cause the stopping of arc scraping blade 6 for touching hair skin first to move downward, and those made touch skin not yet Arc scraping blade 6 then moves down, until all arc scraping blades 6 all touch skin, and at this time due to each sleeve 3 It entirely connects therefore, the pressure in each sleeve 3 is also the same, therefore arc scraping blade 6 touches the power of skin It is certain, had not only can guarantee that the present apparatus can more perfectly be bonded the skin of out-of-flatness position simultaneously but also can guarantee skin in this way The uniform force during clear scrape effectively avoids scraper and manually scrapes caused secondary injury clearly.

2nd, the present apparatus employs the mode of bidirectional-movement during scraping clearly, that is, at initial position, makes first The blade for obtaining the arc scraper plate of the left and right sides is on same horizontal plane, and separately both sides are carried out at the same time clearly two parts to the left and right It scrapes, and the lesion region of homonymy scrapes only carried out the region of half clearly, but the clear time trend for scraping large area is the same, it is this It scrapes mode clearly effectively to solve during skin is scraped clearly, the skin pine that skin occurs due to being scratched by scraper It is dynamic, and this loosening effect can realize the fold that skin is caused when skin is scraped clearly, and this fold is easily to cause to scrape To the secondary injury of skin, tradition solves to be that a hand is wanted to carry out pressing to ensure that skin will not wrinkle clever brother during this problem knife Realization is scraped clearly, but this mode is not laborsaving, in the present apparatus, is scraped clearly using two-way simultaneous, even if the arc scraping blade 6 of both sides is clear Scrape tool simultaneously again for offside it is clear scrape provide effective pressing effect realize scrape clearly during be not in that skin loosens, So as to avoid the secondary injury to skin.

3rd, traditional skin, which is scraped clearly, is usually used scraper in one reciprocating motion of skin surface progress while realizes forward It promotes, the benefit done so is exactly that reciprocal being advanced slowly is that the grinding on surface is carried out to skin, by being slowly ground Lesion region on skin loosens, the advantage of doing so is that avoiding directly carrying out scraping clearly that skin is caused to damage, existing skin Scraper is typically all to use disposably to scrape clearly, such to scrape mode clearly, is directly scraped using blade, scrapes process clearly to suffering from The skin damage of person is huge, while cannot guarantee that cutaneous lesions area is thorough with that can scrape clearly, and present apparatus simulation people Work is scraped clearly, realizes that clear scrape carries out realizing that skin scrapes clearly in the process more human nature with grinding jointly by reciprocal being slowly advanced Change.

4th, the present apparatus drives roller 9 to rotate by a stepper motor 10 in lasting rotation, and roller 9 slowly realize by rotation The lasting drop-down of first rope 11 connecting rod 7 hinged to two pushes so as to fulfill the left and right to supporting rod 1, due to Stepper motor 10 is to continue rotation therefore, is the continuous passage to two 1 initial positions of supporting rod during this, is exactly this The process slowly elapsed forward of device, partial gear 16 is engaged with gear 15 drives reel 13 to be driven through the second rope 14 Roller 9 moves down, and partial gear 16 is not engaged with gear 15, and the reset of roller 9 is realized under the action of tension spring 8, this process is To move back and forth, and the motion process that this is moved back and forth is a process at regular time and quantity, and here it is the present apparatus to carry out mill skin Process, since the rotating speed of partial gear 16 is higher than 10 rotating speed of stepper motor, every time be slowly advanced during into Multiple reciprocating motion of having gone, which is realized, scrapes clearly more thoroughly, but also clear scrape more mild, hommization.

Present inventive concept is novel, and clever structure is highly practical, realizes that each arc scraping blade contacts skin by forbay Power be all wait it is big, and pass through arc scraping blade with left and right be carried out at the same time it is clear scrape ensure that it is clear scrape skin during it is more comfortable And hommization, while realize that skin is scraped clearly more thorough by the way of being back and forth slowly advanced.
