[0030] Please refer to Figure 1 This embodiment provides a medical accessory positioning device 100, including a first positioning portion 110 and a second positioning portion 120. One side of the part to be positioned is limited and fixed by the first positioning portion 110, and the other side is limited and fixed by the second positioning portion 120. The second positioning portion 120 can move relative to the first positioning portion 110 to approach or move away from the first positioning portion 110.

[0031] Specifically, if Figure 1 As shown, the present application provides a medical accessory positioning device 100 , which consists of a first positioning portion 110 and a second positioning portion 120 . The second positioning portion 120 can move relative to the first positioning portion 110 to adjust the relative distance between the second positioning portion 120 and the first positioning portion 110 .

[0032] One side of the part to be positioned is limited and fixed by the first positioning part 110, and the other side is limited and fixed by the second positioning part 120. After both sides of the part to be positioned are limited and fixed, the second positioning part 120 can adjust the relative distance between it and the first positioning part 110 to adapt to the structural size of the part to be positioned, thereby positioning the part to be positioned.

[0033] Existing positioning devices typically clamp the outer edge of the part to be positioned. However, due to the limited clamping space of the clamping member, the size and shape of the part to be positioned are highly demanding, resulting in poor applicability and flexibility of the positioning device. However, the present application, through the provision of a first positioning portion 110 and a second positioning portion 120 that can be relatively movable, can adapt to the positioning of parts of various sizes and shapes, thereby improving the flexibility of the positioning process.

[0034] It should be noted that, first, Figure 1 As shown, in one embodiment of the present application, the first positioning portion 110 and the second positioning portion 120 both include a base 150 , on which at least one positioning column 151 is vertically arranged, and a positioning pin 130 is arranged at one end of the positioning column 151 away from the base 150 .

[0035] Specifically, the base 150 is used to support the positioning column 151. To facilitate the rapid positioning of the part to be positioned, the positioning column 151 is provided with a positioning pin 130. The positioning holes on opposite sides of the part to be positioned can be respectively inserted into the positioning pins 130 on the first positioning portion 110 and the positioning pins 130 on the second positioning portion 120 to achieve the positional fixation of the part to be positioned. The second positioning portion 120 can adjust the relative distance between itself and the first positioning portion 110 to adapt to the structural dimensions of the part to be positioned, thereby positioning the part to be positioned via the positioning pins 130.

[0036] Second, if Figure 1 As shown, in one embodiment of the present application, the first positioning portion 110 and the second positioning portion 120 are arranged along a first direction a, and the first direction a is in the same direction as the extension direction of the part to be positioned. Specifically, the first positioning portion 110 and the second positioning portion 120 can be arranged along the extension direction of the part to be positioned to respectively limit and fix the part to be positioned on opposite sides along the extension direction;

[0037] In another embodiment of the present application, the first positioning portion 110 and the second positioning portion 120 are arranged along a second direction b, and the second direction b is perpendicular to the extension direction of the member to be positioned. Specifically, the first positioning portion 110 and the second positioning portion 120 can also be arranged along a direction perpendicular to the extension direction of the member to be positioned to respectively limit and fix the two sides of the member to be positioned perpendicular to the extension direction.

[0038] The present application does not impose any limitation on the specific arrangement direction of the first positioning portion 110 and the second positioning portion 120, as long as it can be ensured that the first positioning portion 110 and the second positioning portion 120 can both limit and fix the positioning member, and the second positioning portion 120 can move relative to the first positioning portion 110 to position the positioning member.

[0039] This application provides a medical accessory positioning device 100, comprising a first positioning portion 110 and a second positioning portion 120. One side of the component to be positioned is fixed by the first positioning portion 110, and the other side is fixed by the second positioning portion 120. The second positioning portion 120 is movable relative to the first positioning portion 110 to move closer to or further away from the first positioning portion 110. The medical accessory positioning device 100 can accommodate the positioning of materials of varying structural dimensions by varying the positions of two adjacent positioning pins 130, thereby increasing the flexibility of the positioning process.

[0040] In one embodiment of the present application, please refer to Figure 2 and Figure 3 An elastic member 140 is provided between the first positioning portion 110 and the second positioning portion 120 , and the elastic member 140 can drive the second positioning portion 120 away from or close to the first positioning portion 110 .

[0041] Specifically, if Figure 2 and Figure 3 As shown, in order to ensure that the movement process of the second positioning portion 120 relative to the first positioning portion 110 is smoother and more efficient, an elastic member 140 is provided between the first positioning portion 110 and the second positioning portion 120. The elastic member 140 can drive the second positioning portion 120 away from or close to the second positioning portion 120 to adjust the spacing distance between the second positioning portion 120 and the first positioning portion 110 to match the shape and size of the part to be positioned.

[0042] For example, Figure 2 As shown, when a plurality of positioning posts 151 are vertically arranged on the base 150 of the first positioning portion 110 , a preset interval is provided between any two adjacent positioning posts 151 .

[0043] Specifically, if Figure 2 As shown, in order to ensure that the first positioning portion 110 can achieve the positioning accuracy of one side of the part to be positioned, a plurality of positioning posts 151 are vertically arranged on the first positioning portion 110, and a preset interval is set between two adjacent positioning posts 151 to achieve multi-point positioning of one side of the part to be positioned. Figure 4 As shown, in a specific embodiment of the present application, two positioning posts 151 are provided on the base 150 of the first positioning post 151 , and a preset interval is provided between the two positioning posts 151 to position the opposite ends of one side of the positioning member.

[0044] For example, Figure 2 As shown, when a plurality of positioning posts 151 are vertically arranged on the base 150 of the second positioning portion 120 , a preset interval is provided between any two adjacent positioning posts 151 .

[0045] Specifically, if Figure 2 As shown, in order to ensure that the second positioning portion 120 can achieve the positioning accuracy of one side of the part to be positioned, a plurality of positioning posts 151 are vertically arranged on the second positioning portion 120, and a preset interval is set between two adjacent positioning posts 151 to achieve multi-point positioning of one side of the part to be positioned. Figure 4 As shown, in a specific embodiment of the present application, two positioning posts 151 are provided on the base 150 of the second positioning post 151 , and a preset interval is provided between the two positioning posts 151 to position the opposite ends of one side of the positioning member.

[0046] In one embodiment of the present application, the first positioning portion 110 includes at least one base 150, and the second positioning portion 120 includes at least one base 150; when the base 150 includes multiple bases, an elastic member 140 is provided between two adjacent bases 150, and the elastic member 140 can drive the positioning pins 130 on any two adjacent bases 150 to move away from or approach each other (not shown in the figure).

[0047] Specifically, the first positioning portion 110 and the second positioning portion 120 each include at least one base 150; when the first positioning portion 110 and the second positioning portion 120 each include one base 150, at least one positioning column 151 is vertically arranged on the base 150; when the first positioning portion 110 and the second positioning portion 120 each include multiple bases 150, the multiple bases 150 are arranged side by side along the extension direction of the part to be positioned, or the multiple bases 150 are arranged side by side in a direction perpendicular to the extension direction of the part to be positioned; each base 150 is provided with at least one positioning column 151, and an elastic member 140 is provided between adjacent two bases 150, and the elastic member 140 can drive the adjacent two bases 150 to move closer to or away from each other.

[0048] By providing the first positioning portion 110 and the second positioning portion 120 with multiple bases 150, the positioning accuracy of the medical accessory positioning device 100 can be further improved. The relative ends of the part to be positioned can be more accurately positioned by the multiple bases 150 of the first positioning portion 110 or the second positioning portion 120. The multiple bases 150 of the first positioning portion 110 or the second positioning portion 120 can be moved closer to or farther away from each other to adapt to the shape and size of the part to be assembled, thereby further improving the flexibility of the medical accessory positioning device 100 in the positioning process.

[0049] Alternatively, as Figure 4 As shown, at least one support column 160 is provided on the side of the base 150 of the first positioning portion 110 close to the second positioning portion 120, or at least one support column 160 is provided on the side of the second positioning portion 120 close to the first positioning portion 110; the support column 160 is perpendicular to the base 150 to support the part to be positioned which is sleeved on the positioning pin 130.

[0050] Specifically, if Figure 4 As shown, a support column 160 is disposed between the first positioning portion 110 and the second positioning portion 120 and is perpendicularly connected to the base 150. The support column 160 is used to support the positioning member that is sleeved on the positioning pin 130, preventing the center portion of the positioning member from sagging. The support column 160 can be disposed on the base 150 of the first positioning portion 110 or the base 150 of the second positioning portion 120. Preferably, the support column 160 is disposed at the center of the two diagonally arranged positioning pins 130 to support the center of the positioning member.

[0051] In one embodiment of the present application, Figure 1 As shown, the medical accessory positioning device 100 further includes a support base 170 , the first positioning portion 110 is disposed on a plate surface of the support base 170 , and the second positioning portion 120 can move along the plate surface of the support base 170 to approach or move away from the first positioning portion 110 .

[0052] Specifically, if Figure 1 As shown, the medical accessory positioning device 100 further includes a support base 170, which is used to support the base 150 of the first positioning portion 110. When the first positioning portion 110 includes multiple bases 150, the multiple bases 150 can be evenly distributed on the first positioning portion 110. The second positioning portion 120 can move along the surface of the support base 170 to move closer to or away from the first positioning portion 110, making the movement of the second positioning portion 120 more stable and reliable.

[0053] The above description is merely an optional embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.

[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
