All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a double-axis tungsten wire winding machine, comprising: a fixed frame 1 and a catheter 2, the fixed frame 1 is installed on the wire walking device of the double-axis tungsten wire winding machine, the catheter 2 is provided with a flange on the side wall of the wire feeding end, a clamping plate 5 is movably connected on the surface of the fixed frame 1, and a plurality of groups of sharp cones 6 are provided on the inner wall of the clamping plate 5, and the plurality of groups of sharp cones 6 penetrate into the flange of the catheter 2, and two groups of clamping plates 5 are provided, and the two groups of clamping plates 5 are symmetrically distributed about the catheter 2.

[0024] When the pipe 2 is installed in the fixing frame 1, the two sets of clamps 5 are first separated to both sides, and then the pipe 2 is inserted into the fixing frame 1, and the end of the pipe 2 provided with the flange is set at the end of the fixing frame 1 where the clamps 5 are installed, and then the two sets of clamps 5 are closed toward the middle, so that the sharp cone 6 on the inner wall of the clamps 5 pierces the flange of the pipe 2, and the pipe 2 can be limited in the fixing frame 1. When the pipe 2 needs to be replaced, the two sets of clamps 5 are separated to both sides again, so that the sharp cone 6 is away from the flange of the pipe 2, and the limitation of the pipe 2 and the fixing frame 1 can be released, and then the old pipe 2 is taken out of the fixing frame 1, and the new pipe 2 is inserted into the fixing frame 1, and finally the two sets of clamps 5 are closed again, so that the sharp cone 6 pierces the new pipe 2 to limit the new pipe 2, and the replacement of the pipe 2 can be completed, making the replacement of the pipe 2 very convenient and quick.

[0025] Embodiment 2

[0026] On the basis of Example 1, in order to realize the connection between the splint 5 and the fixing frame 1, a connecting seat 3 is fixed to the top of the fixing frame 1, and a connecting groove 7 is opened on the surface of the connecting seat 3. A connecting rod 8 is movably inserted in the connecting groove 7, and a connecting plate 4 is fixed to the end of the connecting rod 8 extending out of the connecting groove 7, and a spring plate 9 is fixed to the end of the connecting rod 8 extending into the connecting groove 7. The spring plate 9 has a circular plate-like structure, and the diameter of the spring plate 9 is larger than the opening diameter of the connecting groove 7 on the surface of the connecting seat 3. The side of the connecting plate 4 is fixed to the splint 5.

[0027] The side of the splint 5 is fixed to the connecting plate 4, and the connecting rod 8 is fixed on the surface of the connecting plate 4. The other end of the connecting rod 8 extends into the connecting groove 7. The connecting groove 7 is opened on the side of the connecting seat 3 fixed to the top of the fixing frame 1. At the same time, a spring plate 9 is fixed to the end of the connecting rod 8 extending into the connecting groove 7. The diameter of the spring plate 9 is larger than the opening diameter of the connecting groove 7. When the two groups of splints 5 are separated to both sides, the connecting rod 8 extends a longer distance from the connecting groove 7, but the existence of the spring plate 9 prevents the connecting rod 8 from falling out of the connecting groove 7, thereby realizing the connection between the splint 5 and the fixing frame 1.

[0028] Embodiment 3

[0029] On the basis of the second embodiment, in order to achieve more labor-saving penetration of the pointed cone 6 into the flange of the catheter 2, a spring 10 is sleeved on the rod body of the connecting rod 8, one end of the spring 10 is against the surface of the spring plate 9, and the other end of the spring 10 is against the inner wall of the connecting groove 7.

[0030] When the two groups of splints 5 are separated to both sides, the two groups of connecting plates 4 are also separated to both sides, so that the connecting rod 8 extends a longer distance from the connecting groove 7, and then the spring plate 9 is close to the opening of the connecting groove 7. The movement of the spring plate 9 compresses the spring 10. When the catheter 2 is placed in the fixing frame 1, it is only necessary to loosen the connecting plate 4. The spring 10 quickly pushes the spring plate 9 back to its original position under the action of its own elasticity. The movement of the spring plate 9 causes the two groups of connecting plates 4 to close quickly through the connecting rod 8, and then the two groups of splints 5 are also quickly closed. The rapid closing of the splints 5 causes the pointed cone 6 to hit the catheter 2 at a faster speed, so that the pointed cone 6 automatically penetrates the flange of the catheter 2, achieving a more labor-saving way of making the pointed cone 6 penetrate the flange of the catheter 2.

[0031] Embodiment 4

[0032] On the basis of the third embodiment, in order to facilitate the separation of the two groups of clamping plates 5 to both sides, a handle 11 is fixed on the outer wall of the connecting plate 4 .

[0033] The outer wall of the connecting plate 4 is provided with a fixed handle 11. The two connecting plates 4 can be separated to both sides by simply pulling the two handles 11 to both sides, thereby driving the two clamping plates 5 to separate to both sides, thereby facilitating the separation of the two clamping plates 5 to both sides.

[0034] In actual use, when installing the catheter 2 in the fixing frame 1, first separate the two groups of clamps 5 to both sides, then insert the catheter 2 into the fixing frame 1, and make the end of the catheter 2 provided with the flange be set at the end of the fixing frame 1 provided with the clamp 5, then close the two groups of clamps 5 to the middle, so that the sharp cone 6 on the inner wall of the clamp 5 pierces the flange of the catheter 2, so that the catheter 2 can be limited in the fixing frame 1. When the catheter 2 needs to be replaced, separate the two groups of clamps 5 to both sides again, so that the sharp cone 6 is away from the flange of the catheter 2, so that the limitation of the catheter 2 and the fixing frame 1 can be released, and then the old catheter 2 can be removed from the fixing frame 1. The two sets of clamps 5 are finally closed again, and the sharp cone 6 is inserted into the new catheter 2 to limit the new catheter 2, so that the replacement of the catheter 2 can be completed, making the replacement of the catheter 2 very convenient and quick; the side of the clamp 5 is fixed with the connecting plate 4, and the surface of the connecting plate 4 is fixed with a connecting rod 8, and the other end of the connecting rod 8 extends into the connecting groove 7, and the connecting groove 7 is provided on the side of the connecting seat 3 fixed at the top of the fixing frame 1, and at the same time, the end of the connecting rod 8 extending into the connecting groove 7 is also fixed with a spring plate 9, and the diameter of the spring plate 9 is larger than the opening of the connecting groove 7. When the two groups of clamps 5 are separated to both sides, the connecting rod 8 extends out of the connecting groove 7 for a longer distance, but the presence of the spring plate 9 prevents the connecting rod 8 from falling out of the connecting groove 7, thereby realizing the connection between the clamps 5 and the fixing frame 1; when the two groups of clamps 5 are separated to both sides, the two groups of connecting plates 4 are also separated to both sides, thereby making the connecting rod 8 extend out of the connecting groove 7 for a longer distance, thereby making the spring plate 9 close to the opening of the connecting groove 7, and the movement of the spring plate 9 makes the spring 10 compressed. When the catheter 2 is placed in the fixing frame 1, it only needs to loosen the connecting plate 4, and the spring 10 will be released by itself. Under the action of force, the spring plate 9 is quickly pushed back to its original position. The movement of the spring plate 9 causes the two groups of connecting plates 4 to close quickly through the connecting rod 8, and then the two groups of clamping plates 5 are also quickly closed. The rapid closing of the clamping plates 5 causes the pointed cone 6 to hit the catheter 2 at a faster speed, so that the pointed cone 6 automatically pierces the flange of the catheter 2, which makes it easier to make the pointed cone 6 pierce the flange of the catheter 2; a fixed handle 11 is provided on the outer wall of the connecting plate 4, and the two groups of handles 11 only need to be pulled to both sides to separate the two groups of connecting plates 4 to both sides, thereby driving the two groups of clamping plates 5 to separate to both sides, which makes it convenient to separate the two groups of clamping plates 5 to both sides.
