Specific implementation mode

The utility model is further illustrated in conjunction with the drawings and specific embodiments.

Referring to figs. 1 to Fig. 4, the present embodiment provides a kind of adjustable line-throwing appliance, including launching tube 1, it is set to 1 rear end of launching tube Compression gas tank 2, on launching tube 1 for opening and closing the trigger device 3 of compression gas tank 2, the slide bar 4 in launching tube 1, even The rope bar 5 of splicing 6, the launching tube 1 include for installing the matrix part 11 of slide bar, connection matrix part 11 for installing rope bar 5 guide cylinder 12, it is described rope bar 5 include ontology 51, set on 51 rear end of ontology annular recess 52, be set to ontology 51 on it is close At fastening part for connecting the columned interconnecting piece 53 of rope 6, set close to one end of matrix part 11 in the guide cylinder 12 It is useful for the holding device of holding rope bar annular recess 52, the holding device includes annular seating 121, evenly distributedly opens up In the pilot hole 122 on 121 inner ring of annular seating, the spring 123 in pilot hole 122, the steel on 123 free end of spring Pearl 124, when spring 123 in a free state, steel ball 124 stretch out annular seating 121 length be less than 1/3 diameter, can set For 1/4 diameter, the guide cylinder 12 is equipped with the notch 125 of cylindrical screw threadiness, and the interconnecting piece 53 is located in notch 125, The both ends of the notch 125 are less than 240 degree with the angle in the guide cylinder center of circle and more than 60 degree, specifically can be set as 180 degree.Institute State guide cylinder 12 and be connected with the mode that matrix part 11 is connected through a screw thread, the mode that the annular seating 121 is connected through a screw thread with Guide cylinder 12 is connected.12 inner wall of the guide cylinder is equipped with and is led along one of 12 axle center array of guide cylinder based on notch 125 To groove 126, the rope bar 5 is equipped with the spherical surface hill 54 coordinated with guiding groove 126.

Above-mentioned guiding groove can be arranged to multiple, and spherical surface hill can be slightly smaller than guiding groove, as spherical surface is convex The gap risen and be oriented between groove is 0.1mm, can ensure the smoothness of rope bar sliding in this way；The both ends of above-mentioned notch 125 It is less than 240 degree with the angle in the guide cylinder center of circle and more than 60 degree, multiple guide cylinders, each guiding can be made according to actual needs The spiral angle of the notch 125 of cylinder is different, is replaced with realizing, so that it is guaranteed that transmitting is accurate.

In use, interconnecting piece is filled in along notch, bar of restricting this when can be rotated slowly along the notch of cylindrical screw threadiness, Until annular recess is caught in holding device, to realize holding, this holding is slight, after slide bar hits rope bar, card The state of setting will release.

The holding of rope bar, and circular helix may be implemented by the setting of restrict bar, guide cylinder for this adjustable line-throwing appliance The setting of the spiral angle of the notch of shape may be implemented the adjusting of rope bar rotation size, be conducive to the adjusting of accuracy, Er Qieke So that range is farther, injection angle is more accurate, it is more accurate to project curve；Further, more than one guiding groove is set And spherical surface hill, can be connected portion, rotation when rope bar projects be realized, to improve range, precision；Further, lead to It crosses the guide cylinder and is connected with the mode that matrix part is connected through a screw thread, the mode and guiding that the annular seating is connected through a screw thread Cylinder is connected, and can be convenient to dismantle in this way, and be also convenient for the assembly in annular seating.

Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art answers This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details On the utility model can be made a variety of changes, be the scope of protection of the utility model.
