Detailed description of the invention
Illustrate the present invention below in conjunction with accompanying drawing, as shown in Figure 1, the present invention includes casing 5, handle 1, also comprise the shaking device be fixed on casing 5, mechanical reduction gear, rack gearing, geared assembly 6; Described rack gearing comprises tooth bar 4, and the bottom of described tooth bar 4 is fixed with jaw leaf spring 11; Described shaking device comprises the driving shaft 16 with line shaft 17 coaxial rotation, described driving shaft 16 is arranged the bevel gear 15 simultaneously rotated, the lower end of described driving shaft 16 arranges bumper 13, and nail extracting device 9 arranges corresponding bumper 13, and bumper 13 structure as shown in Figure 7; Described mechanical reduction gear comprises the gear train that multiple coaxial gear wheel and pinion form, as gear train 1, gear train 2 18, gear train 38, gear train 47, the present embodiment is only a kind of gear transmission mode, in concrete gear drive, gear quantity and gearratio should change to some extent according to different specifications, also can adopt other the kind of drive, final-stage gear is rack drives gear, and the rotation of driving shaft 16 is passed to tooth bar 4 by it; Bevel gear 15 on described driving shaft 16, gear train 1, gear train 2 18, gear train 38, gear train 47 engage successively; The output gear of gear train 47 and rack drives gear, by the transmission step by step of gear, reduced by the high rotating speed of driving shaft 16, the rotation of bevel gear is delivered to tooth bar 4 the most at last; Described geared assembly 6 is delivered on tooth bar 4 by the rotation of rack drives gear; Described geared assembly 6 is connected with driving lever 2, by the movement of driving lever 2 mesh control device 6, controls the engagement of rack drives wheel and rack 4 with this; Described nail extracting device comprises clamp 10, and the inclined-plane, outside of described clamp 10 abuts with the endoporus of described jaw leaf spring 11; The interior hole width of described jaw leaf spring 11 be less than clamp 10 closed after width; The end of described tooth bar 4 is shrinkage pool 19, and described tooth bar 4 is connected with restoring spring 3.
Be illustrated in figure 2 a kind of geared assembly schematic diagram, the meshing gear 23 that rotates through of final-stage gear 21 passes to tooth bar 4, meshing gear is fixing on bearings 22, bearing arranged outside bearing cap 24, bearing cap 24 is connected with driving lever 2, carry out moving axially of mesh control gear by stirring driving lever 2, and then control engaging of final-stage gear 21 and tooth bar 4; The end of tooth bar 4 arranges shrinkage pool 19, and when meshing gear and shrinkage pool 19 position consistency, due to not engagement, under the elastic force effect of return spring 25, geared assembly 6 and tooth bar 4 disengage, and tooth bar then, under the pulling force effect of restoring spring 3, gets back to home position.
Fig. 3, Fig. 4 are another geared assembly schematic diagram, the rotation of this device final-stage gear 21 needs to pass to tooth bar 4 by meshing gear 23, meshing gear 23 is fixing on bearings 22, bearing arranged outside bearing cap 24, bearing cap 24 is connected with driving lever 2, carry out moving axially of mesh control gear by stirring driving lever 2, and then control engaging of final-stage gear 21 and tooth bar 4; This structure is provided with conjugate control mechanism as shown in Figure 2 too.
Geared assembly of the present invention is not limited only to two kinds of forms recited above, can also be other modes, controls final-stage gear and engaging of tooth bar etc. as adopted the mode of active pin shaft.
Fig. 5 is nail extracting device structural representation; Clamp 10 are fixed on clamping plate by bearing pin 96; Arrange roller bearing 97 between two clamp 10, the top of clamp 10 arranges inclined-plane 93, and described inclined-plane 93 is corresponding with the push-and-pull inclined-plane 981 in the push-and-pull portion 98 of pull bar 99; The arranged outside leaf spring 91 on clamp 10 top, described leaf spring 91 is fixed between the outside on clamping plate and clamp 10 top by plate spring pin roll 92; The lower outside of clamp 10 arranges inclined-plane 94 to ensure that clamp 10 insert in the endoporus of jaw leaf spring 11, the interior hole width of described jaw leaf spring 11 be less than clamp 10 closed after width; Under the compressing of described endoporus, clamp 10 close; Described jaw leaf spring 11 as shown in Figure 6, is the shape of a hoof, and namely dimension D 1 is interior hole width, and dimension D 2 is the width after clamp 10 close; Parts 100 are ailhead.
Described line shaft 17 can be the output shaft of electric drill, also can be the output shaft of air drill, can also be the output shaft of motor.
Principle of the present invention is: driving shaft rotates, line shaft and bevel gear coaxial rotation by the driving of line shaft; Initiatively the tip of the axis transmits vibrations to nail extracting device by bumper, and the clamp of nail extracting device open owing to being subject to the effect of leaf spring, under shock effect, clamp press down in the both sides of nail in case nail pulling time clamp nail; The rotation of bevel gear drives multiple geared system, is finally delivered to rack drives gear; Geared assembly controls the engagement of rack drives wheel and rack; When after the engagement of rack drives wheel and rack, tooth bar can move downward, and due to relative motion, nail extracting device lifts; The clamp of nail extracting device close owing to being subject to the size restriction of jaw leaf spring endoporus; After the clamp of nail extracting device and jaw leaf spring disengage, due to the effect on the push-and-pull inclined-plane of pull bar and the inclined-plane of clamp upper inner, clamp still clamp nail; When shrinkage pool and the rack drives Gear Contact of tooth bar end, due to not engagement, meshing gear departs from tooth bar under the action of the spring, and tooth bar also playbacks under the action of the spring.Now, nail has been extracted.
The distance of nail pulling is relevant with the length of tooth bar.
