Bendable hard type water tube

A bendable hard type water tube comprising:

• a first tube;
• a second tube;
• a first seat being a round piece-like body, and a predetermined portion on a periphery thereof being firmly secured to one end of the first tube;
• a first outer side extending from a periphery of the first seat and being connected to the first tube;
• a top edge of the first outer side being extended with a second outer side having a proper height and having an inner diameter larger than that of the first outer side;
• thereby, a first water channel being formed between the first seat and the first and second outer sides;
• an opening being formed at a connection of the first outer side and the first tube so as to communicate the first water channel and the first tube;
• a second seat having a shape approximately corresponding to the piece-like body of the first seat;
• a predetermined portion at the periphery thereof being firmly secured to one end of the second tube;
• a periphery of the second seat being extended to a predetermined length vertically to be aforementioned as a first inner side which being connected to the second tube;
• a top edge of the first inner side being extended with a second inner side having a predetermined height;
• an outer diameter of the second inner side being smaller than an outer diameter of the first inner side, but corresponding to an inner diameter of the first outer side;
• thereby, a second water channel being formed between the second seat and the first and second inner sides;
• an opening being formed at a connection of the first inner side and the second tube so as to communicate the second water channel and the second tube;
• a second inner side being inserted into the first outer side with a predetermined depth so that the first outer side encloses the second inner side;
• a top edge of the second outer side resisting against a top edge of the first inner side;
• thereby, an interior of the first tube, an interior of the second tube, the first water channel and the second water channel being communicated with one another;
• a first buckle having a predetermined height and being a hollow cylinder;
• a plurality of radial teeth being arranged at a periphery of an inner wall of the cylinder;
• one end thereof being firmly secured to a lateral side of the first seat and being in the first water channel;
• the other end thereof being an open end and resisting against the second seat;
• a second buckle having a predetermined height and being a round ring with an outer radius smaller than the distance between the central axis of the first buckle and an outer edge of the teeth;
• one end thereof being firmly secured to a lateral side of the second seat and in the second water channel;
• the other end thereof being arranged with a plurality of teeth that are arranged normally along a periphery of the round ring;
• a rotary shaft being a round cylinder with a length approximately equal to the height of the first buckle;
• one end thereof being concentric with the second buckle and they are firmly secured to the second seat by the same side;
• the other end thereof being pivotally installed at a center of the connection between the first buckle and the first seat;
• a third buckle being a round cylinder with a predetermined height and coaxially enclosing the rotary shaft;
• a plurality of teeth being arranged at a lateral side of a circumference thereof;
• each tooth being corresponding to and engaged with teeth of the first buckle and the second buckle;
• an elastic body being installed between the first buckle and the third buckle;
• two end thereof resisting against a connecting end of the first buckle and the third buckle;
• and
• a press being installed at the second seat opposite the second buckle and including a cover and a resisting portion;
• wherein the resisting portion is a rod protruded with a predetermined length toward the second seat and being formed a predetermined portion at a lateral side of the cover;
• the resisting portion passes through an opening installed at the second seat and being located between the second buckle and the rotary shaft;
• thereby, the press moving reciprocally along a long axis of the rotary shaft and then pushing the third buckle through the resisting portion.
