DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 9 As shown, the present invention includes a front rotating mechanism 1 and a rear rotating mechanism 2 arranged in front and back and rotatably connected, the front rotating mechanism 1 includes a branch pressing ring a101 and a branch pressing ring b103 fixed on the left and right sides of the front end surface of the connecting plate a102, the rear rotating mechanism 2 includes a branch pressing ring c202 fixed on the right front end of the connecting plate b201 and a barrel cover 203 on the left rear end, the barrel cover 203 is provided with meshing teeth 4 and a rotating column 3 is fixed on the front end surface of the meshing teeth 4; An insert sleeve 104 is arranged on the rear end face of the connecting plate a102 at a position corresponding to the position of the branch pressing ring b103. An engagement groove 401 which can adapt to the engagement teeth 4 is arranged on the built-in rear end face of the insert sleeve 104. The two are engaged to limit the rotation angle of the rotating mechanism. Of course, the division value of the rotation angle is related to the number of teeth of the engagement teeth 4. The insert sleeve 104 and the branch pressing ring b103 are penetrated from front to back to form a cavity. When the rotating column 3 is inserted into the cavity, the insert sleeve 104 is completely inserted into the cylinder cover 203. The front rotating mechanism 1 and the rear rotating mechanism 2 are both made of plastic material that is molded by one-time injection molding, that is, only two sets of injection molds are needed during manufacturing, and the relevant components on the rotating mechanism are not installed and fixed later.

[0020] refer to Figure 5 The cavity formed by the insert 104, the connecting plate a102 and the pressing ring b103 includes a straight cylinder cavity 2031 located in front of the meshing groove 401, and two narrower clamping cavities 2032 are arranged in front of the straight cylinder cavity 2031. A positioning cavity 2033 with a cavity wall concave into an arc shape is separated between the front and rear clamping cavities 2032. The inner diameters of the clamping cavity 2032 and the positioning cavity 2033 are both smaller than the inner diameter of the straight cylinder cavity 2031. Of course, an inclined transition cavity wall is also arranged between the straight cylinder cavity 2031 and the clamping cavity 2032 for easy buffering. A travel clamping cavity 2034 smaller than its diameter is arranged in front of the positioning cavity 2032 to prevent the rear rotating mechanism 2 from falling off, and a travel cavity 2035 larger than its diameter is arranged at the front end of the travel clamping cavity 2034.

[0021] refer to Figure 6 The rotating column 3 includes a bearing column 301 arranged at the front end of the meshing tooth 4, and the front end of the bearing column 301 is provided with two locking columns 302 separated by an intermediate positioning arc ring 303. The positioning arc ring 303 protrudes outward into an arc shape along the outer wall of the front and rear side locking columns 302, that is, when the positioning arc ring 303 moves forward, it will definitely undergo elastic deformation due to the extrusion of the locking cavity 2032; the positioning cavity 2033 is adapted to the positioning arc ring 303, which is the key point for the front and rear limit of the device to prevent movement, and plays a clamping role; the front end of the locking column 302 is provided with a stroke column 304 smaller than its diameter, and the other end of the stroke column 304 is provided with a clamping head 305, and the clamping head 305 is cut into a two-petal structure and its outer diameter is larger than the stroke clamping cavity 2034. The two-petal structure facilitates the plastic material to be squeezed and deformed when passing from the back to the front, and then passes through the cavity of the front rotating mechanism 1.

[0022] refer to Figure 7 When the rotating column 3 is fully inserted into the cavity, the device is in a state of being limited and unable to rotate; the rear end face of the insert cylinder 104 is in contact with the bottom surface inside the cylinder cover 203, the straight cylinder cavity 2031 is in clearance with the bearing column 301, and the positioning cavity 2032 is in clearance with the positioning column 302; the positioning cavity 2033 is clamped with the positioning arc ring 303 and is clamped by the positioning cavity 2032 with a smaller inner diameter at the front and rear. Of course, when the positioning arc ring 303 passes through the rear end positioning cavity 2032, due to the elastic properties of the plastic itself and the hollow effect of the deformation hole groove 5, the positioning arc ring 303 can undergo partial elastic deformation to reduce the diameter, and the stroke column 304 extends out of the stroke cavity 2035 outside the stroke clamping cavity 2034, and the clamping head 305 is located in the stroke cavity 2035 and the two are not in contact.

[0023] refer to Fig.10 When the positioning arc ring 303 is located in the straight cylindrical cavity 2031 and the chuck 305 is still located in the stroke cavity 2035, the meshing groove 401 can be separated from the meshing teeth 4 in an interlaced manner front and back. At this time, the front rotating mechanism 1 and the rear rotating mechanism 2 can rotate freely, that is, the deflection angles of the two can be adjusted so that the branches grow along a predetermined trajectory.

[0024] The external shapes of the branch pressing ring a101, the branch pressing ring b103 and the branch pressing ring c202 are completely consistent, all extending from the concave arc in the middle to both ends, which is conducive to supporting the branches, and the interiors are all hollow structures to reduce the overall weight. The front ends of the three are flush and the front and rear centers are located in the same plane, so the branch pressing ring c202 at the rear end will be slightly larger than the other two; it can effectively prevent the branches from being dislocated and then detached.

[0025] The connecting plate a102 and the connecting plate b201 are both in a curved inferior arc shape. Compared with a straight line, the inferior arc shape can smoothly transition along the bending direction of the branch, while improving the bearing capacity of the connecting plate and preventing rigid breakage.

[0026] The rear end surface of the barrel cover 203 is provided with a plurality of through-holes to further reduce the weight of the main body.

[0027] A deformation hole groove 5 is provided on the rear end surface of the barrel cover 203. The deformation hole groove 5 extends from the rear end surface to the inside of the stroke column 304 and the inner diameter gradually decreases, which is conducive to the slight deformation of the rotating column 3 body under compression in the cavity.

[0028] The two-piece clamp 305 has a diameter that gradually decreases from the back to the front and is truncated into a cone shape, so as to facilitate passing through the cavity.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
