[0047] The handle 2 is arranged at one end of the support tube 1.
[0048] In use, the thin tube 6 is placed in the first limiting groove 11, at this time, the thin tube 6 still has a part outside the first limiting groove 11, the outer wall of this part is tightly attached to the inner wall of the thick tube 7. The thin tube 6 and the supporting tube 1 are inserted into the thick tube 7, through the support of the supporting tube 1, the welding position of the thin tube 6 and the thick tube 7 of the medical water jet is tightly attached, so as to ensure the welding quality between the thin tube 6 and the thick tube 7, and further ensure the product quality of the medical water jet.
[0049] Please refer to Figure 1 and Figure 3 , at least a part of the side surface of the handle 2 is parallel to the plane where the opening of the first limiting groove 11 is located.
[0050] In this embodiment, the handle 2 is a rectangular body, the top surface is parallel to the plane where the opening of the first limiting groove 11 is located. By such arrangement, the position of the thin tube 6 inside the thick tube 7 can be reminded to the worker, and at the same time, due to the arrangement of the handle 2, the relative position of the thin tube 6 and the thick tube 7 can also be adjusted by rotating the handle 2.
[0051] Specifically, the handle 2 is provided with a insertion hole 21, one end of the supporting tube 1 is inserted into the insertion hole 21. Through such structure, the handle 2 and the supporting tube 1 are connected together.
[0052] The insertion hole 21 is provided with a limiting part 211, the limiting part 211 is used for limiting the relative rotation of the supporting tube 1 relative to the insertion hole 21, the shape of the end of the supporting tube 1 inserted into the insertion hole 21 is matched with the insertion hole 21.
[0053] Generally, in order to match the shape inside the thick tube 7, the cross section of the supporting tube 1 at the position where the first limiting groove 11 is not arranged is usually circular, the supporting tube 1 is inserted into the insertion hole 21, in order to avoid the relative rotation of the supporting tube 1 and the insertion hole 21, so that the top surface of the handle 2 is not parallel to the plane where the opening of the first limiting groove 11 is located, the limiting part 211 is arranged, in this embodiment, the limiting part 211 is a plane arranged on the inner wall of the insertion hole 21, the shape of the end of the supporting tube 1 is matched with the insertion hole 21, so that the limiting part 211 limits the relative rotation of the supporting tube 1 in the insertion hole 21.
[0054] In this embodiment, the end of the first limiting groove 11 away from the handle 2 extends to the end of the supporting tube 1.
[0055] Since the end of the thick tube 7 is provided with a through hole 71, and the end of the thin tube 6 also needs to be arranged corresponding to the through hole 71, therefore the supporting tube 1 cannot be arranged too long, the first limiting groove 11 is arranged to extend to the end of the supporting tube 1 away from the handle 2, when the thin tube 6 is in the first limiting groove 11, the end of the thin tube 6 can be extended out of the first limiting groove 11.
