The specific embodiment

Now lift following examples and by reference to the accompanying drawings structure of the present utility model and effect be elaborated.Yet, having in the utility model field and know that usually the knowledgeable should be able to understand, these detailed descriptions and implement the cited specific embodiment of the utility model only are used for explanation the utility model, are not be used to limiting scope of patent protection of the present utility model.

As Fig. 1～shown in Figure 5, the automatic clipping device 10 that the utility model one preferred embodiment provides includes a driver 20, a gear unit 30, and one prunes unit 40.

Driver 20 includes a shell 22 in appearance, and a driving shaft 24 that can opposite shell 22 rotates centered by an axis L, and an end of shell 22 has an internal thread part 222, and an end of driving shaft 24 has an outer toothed portion 242.In the present embodiment, driver 20 is an air motor, and its internal structure and operating principle belong to known techniques, holds the applicant in this not narration in detail.Driver 20 is not limited with air motor, can be also electro-motor, perhaps the rotating driver of other kinds.

Gear unit 30 includes a train of reduction gears 32, a tumbler 34, a bearing 36, and a branch sleeve 38.

Train of reduction gears 32 includes an internal gear 322, three external gears 324 and three axostylus axostyles 326, internal gear 322 has an external thread part 322a, the rear section of external thread part 322a is bolted in the internal thread part 222 of the shell 22 of driver 20, the outer toothed portion 242 of each 324 whiles of external gear with internal gear 322 and driving shaft 24 meshes, the rear section of each axostylus axostyle 326 is inserted in respectively each external gear 324 central authorities, thereby each axostylus axostyle 326 is off-axis L.Thus, internal gear 322 is fixing with the shell 22 of driver 20, and each external gear 324 can be activated that axle 24 drives and rotation and simultaneously around driving shaft 24 revolution, and each axostylus axostyle 326 is also around driving shaft 24 revolution simultaneously.Wherein, the number of external gear 324 can give increase and decrease, and at least one external gear 324 collocation one axostylus axostyles can be reached its effect.

Tumbler 34 has a cylindrical body 342, and the base 344 and the projection 346 that are connected in integratedly respectively body 342 2 ends, body 342 and base 344 joining places are provided with the groove 342a of a ring-type, 344 of bases are provided with the three axial inserting hole 344a that are parallel to body 342, the acting as to be beneficial to of groove 342a is drilled with each inserting hole 344a, but tumbler 34 also can not have groove 342a.The front section of the axostylus axostyle 326 of train of reduction gears 32 is inserted in respectively each inserting hole 344a.Thus, each external gear 324 and axostylus axostyle 326 can drive tumbler 34 when rotating and rotate centered by axis L, and projection 346 is off-axis L, so projection 346 can be made circular motion when tumbler 34 rotation.It is worth mentioning that, each axostylus axostyle 326 also can be one-body molded with base 344, and is perhaps one-body molded with each external gear 324 respectively.Automatically clipping device 10 also can not include train of reduction gears 32, and directly turns tumbler 34 by driving shaft 24.

Bearing 36 is the roller bearing of commonly using, and is sheathed on the body 342 of tumbler 34.Branch sleeve 38 has an internal thread part 382, and the rear section of internal thread part 382 is the external thread part 322a that is bolted in internal gear 322.Wherein, branch sleeve 38 also can be one-body molded with the shell 22 of driver 20.

Prune unit 40 and include a shell 50, two trimming assemblies 60, and a swing component 70.

Shell 50 is by one first shell spare 51, one second shell spare 52, and five screws 53 of two shell spares 51,52 combinations are formed, one end of shell 50 has the external thread part 55 that an opening 54 and that is positioned at the first shell spare 51 is positioned at opening 54 peripheries, bearing 36 plugs are located at opening 54, and external thread part 55 is bolted in the internal thread part 382 of branch sleeve 38, thus, shell 50 is fixing with the shell 22 of driver 20.The other end of shell 50 have two be positioned at the second shell spare 52 and centered by axis L and symmetrical outer surface 56(as shown in Figure 4), two outer surfaces 56 from shell 50 ends towards tilting to extend away from the direction of axis L and towards the direction of driver 20.In addition, shell 50 inside have an accommodation space 57, and two centered by axis L and symmetrical through hole 58, and two through holes 58 from accommodation space 57 towards away from the direction of axis L and tilt to extend towards the direction away from driver 20.

Each trimming assembly 60 includes the second blade 62, a swing arm 64, that one first blade 61, the one and first blade 61 be stacked and is arranged in two blades 61, the first pivot 66 of 62, and second pivot 68 that is arranged in swing arm 64.2 first blades 61 are fixedly arranged on respectively two outer surfaces 56, and two swing arms 64 are arranged in respectively two through holes 58.Each second blade 62 is for to be hubbed at outside shell 50 by the first pivot 66, and has a service portion 622 and a junction 624 that lays respectively at the first pivot 66 2 sides, and further from axis L, and connecting portion 624 is provided with a long slot bore 626 to connecting portion 624 than service portion 622.Each swing arm 64 is hubbed at shell 50 by the second pivot 68, and have the first end 641 and the second end 642 that lay respectively at the second pivot 68 2 sides, first end 641 is positioned at accommodation space 57, and the second end 642 for being located in the long slot bore 626 of the second blade 62 with relatively rotating.

Swing component 70 is hubbed at shell 50 and is positioned at accommodation space 57 by one the 3rd pivot 80, swing component 70 has one first fluting 71 and 1 second fluting 72 that lays respectively at the 3rd pivot 80 2 sides, the projection 346 of tumbler 34 is located in the first fluting 71, swing to drive swing component 70 when tumbler 34 rotates, the first end 641 of two swing arms 64 is located in the second fluting 72, swing driven by swing component 70, and drive simultaneously 2 second blades 62 swings.

Thus, driver 20 is as long as continue to drive tumbler 34 rotations, swing component 70 and two swing arms 64 are reciprocally swinging constantly, and then makes 2 second blade 62 sustained oscillations and move with its service portion 622 and common the generation as the pruning of scissors of 2 first blades 61 respectively.Thus, clipping device 10 not only is applicable to prune carpet wool automatically, and then forms pattern on carpet, the more important thing is, and lightweight, little, the long service life of vibration of automatic clipping device 10, and operate smooth and easy.

It is worth mentioning that, the second blade 62 of each trimming assembly 60 is not limited with aforementioned forms with the connected mode of swing arm 64, as long as the second blade 62 can join with swing arm 64 with relatively rotating, for example long slot bore can be changed and be located at swing arm 64 and make the second blade 62 be arranged in long slot bore.

In the present embodiment, each first pivot 66 is one to be bolted in the bolt of shell 50, and each trimming assembly 60 also includes a Compress Spring 69 that is sheathed on the first pivot 66, and two ends of Compress Spring 69 are connected to respectively the first pivot 66 and the second blade 62.Thus, the Compress Spring 69 of each trimming assembly 60 can provide elastic force to make two

blades

61,62 gap unlikely excessive and lose shearing function, and the user can adapt to by rotating the first pivot 66 elastic force of Compress Spring 69.Yet, aforementionedly be characterized as be used to the performance that makes automatic clipping device 10 better, be not the necessary condition of its effect, therefore, each first pivot 66 is not limited to bolt, and each trimming assembly 60 also can not include Compress Spring 69.

At last, must again illustrate, the constituent components that the utility model discloses in the aforementioned embodiment only for illustrating, is not the scope that limits this case, and substituting or changing of other equivalent elements also should be contained by the scope of patent protection of this case.
