[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Please refer to Figures 1-5 , the present utility model provides a technical solution: A puncture device convenient for angle adjustment, comprising: an upper end cover 1 that is hollow inside and open at the upper end, an arc groove 2 in a spherical shape is opened at the lower end inside the upper end cover 1, a ball catch 3 in a spherical shape is arranged at the lower end inside the upper end cover 1, the lower end of the ball catch 3 is connected to a base 4, the lower end of the base is connected to a puncture cannula 5, interpenetrating holes 6 with the same inner diameter as the puncture cannula 5 are opened in both the ball catch 3 and the base 4, a hose 7 is connected to the upper surface of the ball catch 3 and outside the interpenetrating hole 6, the upper end of the hose 7 extends to the inside of the upper end opening of the upper end cover 1, the diameter of the inner hole of the upper end cover 1 is larger than the outer diameter of the hose 7, a jack 8 is opened at the lower left side inside the upper end cover 1, a fixed rod 9 is connected to the inside of the jack 8 by means of a thread, a rubber pad 10 is connected to the right end of the fixed rod 9, an arc groove with the same radian as the ball catch 3 is opened on the right side of the rubber pad 10, the left side of the fixed rod 9 extends to the left side of the upper end cover 1, and a handle 11 is connected to the left side of the fixed rod 9.
[0027] During use, after inserting the puncture cannula 5 into the body, when it is necessary to adjust the angle of the upper end, turn the handle 11 to a position parallel to the base 4. At this time, the fixed rod 9 will rotate outward, and the rubber pad 10 will disengage from the outer surface of the clamping ball 3. At this time, the upper end cap 1 can be held and waved, and the arc groove 2 will rotate around the outside of the clamping ball 3. At this time, the hose 7 will be stretched, and at the same time, the angle of the upper end cap 1 will be rotated to facilitate the insertion of the device into the insertion hole 6.
[0028] As Figures 1-5 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, arc-shaped bosses 21 are connected in an array on the upper outer surface of the clamping ball 3, and clamping grooves are provided at positions on the inner side of the upper end cap 1 opposite to the positions of the bosses 21.
[0029] Analyzing the above structure, it can be seen that when the upper end cap 1 is moved directly above, the boss 21 will insert into the clamping groove, which can play a role in fixing and reminding the user that the upper end cap 1 is centered.
[0030] As Figures 1-3 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, a hose base 22 is connected to the connection between the outer side of the lower end of the hose 7 and the clamping ball 3.
[0031] Analyzing the above structure, it can be seen that when the angle is rotated, the hose base 22 can prevent the inner side of the upper end cap 1 from hitting the outer surface of the hose 7, causing damage to the surface of the hose 7.
[0032] As Figures 1-3 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, a chamfer is provided at the connection between the arc groove 2 on the inner side of the upper end cap 1 and the internal opening.
[0033] Analyzing the above structure, it can be seen that the chamfer provided at the connection between the arc groove 2 on the inner side of the upper end cap 1 and the internal opening can play a role in reducing friction and prevent plastic particles from falling out after wear.
[0034] As Figures 1-4 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, limiting grooves 23 are provided on the left and right sides of the upper surface of the base 4, limiting baffles 24 are connected to the left and right sides of the lower surface of the upper end cap 1, and the length of the lower end of the limiting baffle 24 is higher than the bottom surface of the limiting groove 23.
[0035] Analyzing the above structure, it can be seen that when the angle of the upper end cap 1 is rotated, when it is rotated to a certain angle, the limiting baffle 24 will be blocked by the limiting groove 23, preventing the angle from rotating too much and causing the hose 7 to be distorted.
[0036] As Figures 1-2As shown, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, the outer surface of the ball 3 is marked with angular markings in a latitudinal and longitudinal line shape, and position indication marks are marked in an array on the outer side of the upper end cover 1.
[0037] Analyzing the above structure, it can be seen that the latitudinal and longitudinal line angles on the outer surface of the ball 3 and the indication marks marked in an array on the outer side of the upper end cover 1 can play a prompting role, facilitating the understanding of the rotation angle.
[0038] As Figures 1-3 As shown, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, the hose 7 is made of stainless steel, and the upper end cover 1, the ball 3, the base 4, and the puncture cannula 5 are all made of plastic.
[0039] Analyzing the above structure, it can be seen that the upper end cover 1, the ball 3, the base 4, and the puncture cannula 5 are all made of plastic, which can reduce the overall weight and facilitate operation. The hose 7 is made of stainless steel, which can prevent the hose 7 from being scratched.
[0040] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
