In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0027] The existing mold testers are of fixed sizes, and one specification corresponds to one mold tester. Usually, in order to meet the needs of different environments, hospitals will prepare a set (several or even more) of tools, which has high costs and management costs.

[0028] To solve the above problems, refer to Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of a mold tester provided in an embodiment of the present application is shown. Figure 2 A schematic structural diagram of a shell and a handle provided in an embodiment of the present application is shown.

[0029] The present application provides a mold tester, comprising a housing 1, a transmission shaft 2, a first slider 3, a second slider 4, two support blocks 5 and a connecting assembly 6. The housing 1 is provided with an inner cavity, and a mounting opening 11 is provided on the circumferential side of the housing 1; the transmission shaft 2 is located in the housing 1 and is rotatably connected to the housing 1, and the transmission shaft 2 is provided with a first thread (not shown in the figure) and a second thread (not shown in the figure) at intervals on the circumferential side of the mounting opening 11, and the second thread is arranged opposite to the first thread; the first slider 3 is located at the mounting opening 11, and the first slider 3 is connected to the transmission shaft 2 through a first thread; the second slider 4 is located at the mounting opening 11, and the second slider 4 is connected to the transmission shaft through a second thread; the two support blocks 5 are respectively located on both sides of the housing 1; the connecting assembly 6 comprises two cross-arranged connecting ribs 61, the connecting rib 61 is movably connected to the first slider 3, and the connecting rib 61 can rotate and slide relative to the first slider 3; the connecting rib 61 is movably connected to the second slider 4, and the connecting rib 61 can rotate and slide relative to the second slider 4; the opposite ends of the connecting rib 61 are respectively movably connected to the two support blocks 5, and the ends of the connecting rib 61 can rotate and slide relative to the support blocks 5.

[0030] It should be understood that the shell 1 is arranged in a cylindrical shape, and the shell 1 can be a square cylinder, a round cylinder or a cylinder of other shapes, and this application does not limit it. Therefore, the shell 1 has an inner cavity, and one end of the shell 1 can be closed to prevent foreign matter from entering the shell 1 and reduce the impact on the parts in the shell 1. The shell 1 is also provided with an installation port 11 on the circumference, and the installation port 11 penetrates the side wall of the shell 1, so that the shell 1 is connected to the outside.

[0031] The transmission shaft 2 is cylindrical and one end of the transmission shaft 2 extends into the housing 1, and the other end of the transmission shaft 2 extends out of the housing 1, which is convenient for the operator to operate. The transmission shaft 2 can rotate in the housing 1, and the transmission shaft 2 is provided with a first thread and a second thread at the installation opening 11. The first thread and the second thread are arranged at intervals along the length direction of the transmission shaft 2, and the first thread and the second thread are arranged oppositely.

[0032] The first slider 3 is located in the inner cavity of the shell 1. The first slider 3 is slidably connected to the shell 1, that is, the first slider 3 can move along the length direction of the shell 1. The first slider 3 is threadedly connected to the transmission shaft 2 through a first thread. When the transmission shaft 2 rotates relative to the shell 1, the first slider 3 moves along the length direction of the shell 1.

[0033] The second slider 4 is located in the inner cavity of the shell 1, and the second slider 4 is slidably connected to the shell 1, that is, the second slider 4 can move along the length direction of the shell 1. The second slider 4 is threadedly connected to the transmission shaft 2 through a second thread. When the transmission shaft 2 rotates relative to the shell 1, the second slider 4 moves along the length direction of the shell 1.

[0034] Since the first thread and the second thread are arranged oppositely, the moving directions of the first slider 3 and the second slider 4 are opposite. In one example, the first slider 3 and the second slider 4 are close to each other, and in another example, the first slider 3 and the second slider 4 are far away from each other.

[0035] Two support blocks 5 are provided, and the two support blocks 5 are respectively located on both sides of the housing 1. The connecting assembly 6 includes two cross-arranged connecting ribs 61, the connecting ribs 61 are movably connected to the first slider 3, and the connecting ribs 61 can rotate and move simultaneously relative to the first slider 3, and the connecting ribs 61 are movably connected to the second slider 4, and the connecting ribs 61 can rotate and move simultaneously relative to the second slider 4. The two ends of the connecting ribs 61 along the length direction are respectively movably connected to the two support blocks 5, and the connecting ribs 61 can rotate and move simultaneously relative to the support blocks 5.

[0036] When the first slider 3 and the second slider 4 approach each other, the opening angle of the two connecting ribs 61 increases, thereby increasing the distance between the two support blocks 5; when the first slider 3 and the second slider 4 move away from each other, the opening angle of the two connecting ribs 61 decreases, thereby reducing the distance between the two support blocks 5.

[0037] During operation, after the mold tester of the present application enters the working area through the endoscope channel or other channels, the appropriate size is selected according to the needs, that is, the movement between the first slider 3 and the second slider 4 is controlled by rotating the transmission shaft 2, thereby controlling the opening angle of the two connecting ribs 61, thereby controlling the distance between the two support blocks 5, and then adjusting the appropriate size of the mold tester. The size of the present application is adjustable, and there is no need to prepare a set (several or even more) of tools, thereby reducing product costs and management costs.

[0038] Reference Figure 1-Figure 4 , Figure 3 A partial structural schematic diagram of a mold tester provided in an embodiment of the present application is shown. Figure 4 A structural schematic diagram of a support block and a connecting assembly provided in an embodiment of the present application is shown.

[0039] In some optional embodiments, the first slider 3 is provided with a first guide column 31, and the connecting rib 61 is provided with a first slide groove 611, and the first guide column 31 can rotate and slide in the first slide groove 611. The first guide column 31 is connected to the first slider 3, and the connection method can be a fixed connection or a detachable connection, which is not limited in this application. In one example, the first guide column 31 is made of the same material as the first slider 3, and the first guide column 31 and the first slider 3 are integrally formed. The first guide column 31 is located at the installation port 11, and the first guide column 31 is cylindrical, so that the first guide column 31 can rotate and slide in the first slide groove 611. The first slide groove 611 is located at the connecting rib 61 and corresponds to the first guide column 31. The first slide groove 611 extends along the length direction of the connecting rib 61, and the end of the first slide groove 611 is arc-shaped, which further improves the smoothness of the first guide column 31 moving in the first slide groove 611.

[0040] Furthermore, since two connecting ribs 61 are provided, two first guide pillars 31 are also provided accordingly.

[0041] In some optional embodiments, the second slider 4 is provided with a second guide column 41, and the connecting rib 61 is provided with a second slide groove 612, and the second guide column 41 can rotate and slide in the second slide groove 612. The second guide column 41 is connected to the second slider 4, and the connection method can be a fixed connection or a detachable connection, which is not limited in this application. In one example, the second guide column 41 is made of the same material as the second slider 4, and the second guide column 41 and the second slider 4 are integrally formed. The second guide column 41 is located at the installation port 11, and the second guide column 41 is cylindrical, so that the second guide column 41 can rotate and slide in the second slide groove 612. The second slide groove 612 is located at the connecting rib 61 and corresponds to the second guide column 41. The second slide groove 612 extends along the length direction of the connecting rib 61, and the end of the second slide groove 612 is arc-shaped, which further improves the smoothness of the second guide column 41 moving in the second slide groove 612.

[0042] Furthermore, since two connecting ribs 61 are provided, two second guide pillars 41 are also provided accordingly.

[0043] In some optional embodiments, two third guide posts 613 are respectively provided at both ends of the connecting rib 61, and the support block 5 is provided with a third slide groove 51, and the third guide post 613 can rotate and slide in the third slide groove 51. The third guide post 613 is connected to the connecting rib 61, and the connection method can be a fixed connection or a detachable connection, which is not limited in this application. In one example, the third guide post 613 is made of the same material as the connecting rib 61, and the third guide post 613 and the connecting rib 61 are integrally formed. The third guide post 613 is connected to the end of the rib 61, and the third guide post 613 is cylindrical, so that the third guide post 613 can rotate and slide in the third slide groove 51. The third slide groove 51 is located at the support block 5 and corresponds to the third guide post 613. The third slide groove 51 extends along the length direction of the support block 5, and the end of the third slide groove 51 is arc-shaped, which further improves the smoothness of the movement of the third guide post 613 in the third slide groove 51.

[0044] Furthermore, since two support blocks 5 are provided, third guide pillars 613 are also provided correspondingly at both ends of the third guide pillar 613 .

[0045] In some optional embodiments, a mounting post 7 is provided at the intersection of the two connecting ribs 61, and the connecting rib 61 is rotatably connected to the mounting post 7. The mounting post 7 is cylindrical, and the intersection of the two connecting ribs 61 is rotatably connected to the mounting post 7, and the mounting post 7 connects the two connecting ribs 61, thereby improving the stability between the connecting components 6.

[0046] In some optional embodiments, the support block 5 is provided with a clearance groove 52 for installing the connecting rib 61. The setting of the clearance groove 52 can leave a position for the installation of the connecting rib 61, reduce the overall volume, and avoid affecting other parts.

[0047] Reference Figure 3 and Figure 4 In some optional embodiments, the side of the support block 5 away from the connecting assembly 6 is arranged in an arc surface. The setting of the arc surface reduces the edges and corners of the support block 5, improves the comfort of the patient, and reduces the harm to the patient.

[0048] In some optional embodiments, the end of the transmission shaft 2 is further connected to an adjusting member 8, and a first ridge 81 is provided on the circumference of the adjusting member 8, and a plurality of first ridges 81 are provided, and the plurality of first ridges 81 are arranged at intervals around the circumference of the adjusting member 8. The adjusting member 8 is cylindrical, and the adjusting member 8 is sleeved on the end of the transmission shaft 2. The adjusting member 8 is fixedly connected to the transmission shaft 2, and when the adjusting member 8 rotates, the transmission shaft 2 can be driven to rotate. The outer diameter of the adjusting member 8 is larger than the outer diameter of the transmission shaft 2, so as to facilitate the operation of the operator. At the same time, a first ridge 81 is provided on the circumference of the adjusting member 8, and the first ridge 81 extends along the height direction of the adjusting member 8. A plurality of first ridges 81 are provided and are arranged at intervals around the circumference of the adjusting member 8. The arrangement of the first ridge 81 can prevent the operator from slipping during operation.

[0049] In some optional embodiments, a scale (not shown) is further provided on the peripheral side of the adjusting member 8. The setting of the scale facilitates the operator to understand the angle of the twisting, and facilitates the operator to accurately control the distance between the two supporting blocks 5.

[0050] Reference Figure 1 and Figure 2 and Figure 5 , Figure 5 A cross-sectional view of a handle provided in an embodiment of the present application is shown, wherein a second edge 12 is provided on the circumferential side of the shell 1, and a plurality of second edges 12 are provided, and the plurality of second edges 12 are spaced around the circumferential side of the shell 1, and a handle 9 is further provided on the end of the shell 1 facing the adjusting member 8, and the handle 9 has an inner cavity, and the inner cavity of the handle 9 is divided into a first chamber 91 and a second chamber 92, wherein the first chamber 91 is sleeved with the shell 1 and a first engaging edge (not shown in the figure) engaged with the first edge 81 is provided on the inner wall of the first chamber 91 to prevent the handle 9 and the shell 1 from rotating relative to each other, and the second chamber 92 is used for sleeved with the adjusting member 8 and a second engaging edge (not shown in the figure) engaged with the second edge 12 is provided on the inner wall of the second chamber 92 to prevent the handle 9 and the adjusting member 8 from rotating relative to each other.

[0051] The handle 9 is cylindrical, and the outer diameter of the handle 9 is larger than the outer diameter of the shell 1. The handle 9 is sleeved on the shell 1 through the first chamber 91, and the circumference of the shell 1 is provided with a second ridge 12, which extends along the height direction of the shell 1. The second ridge 12 is provided in plurality and is arranged at intervals around the circumference of the shell 1. The inner wall of the first chamber 91 is provided with a first engaging ridge engaged with the first ridge 81 to prevent the handle 9 and the shell 1 from rotating relative to each other. When the handle 9 rotates, the shell 1 rotates accordingly. The setting of the handle 9 increases the contact area between the operator and the shell 1, making it easier for the operator to hold and improving the convenience of the operator's operation. However, the handle 9 can reciprocate along the height direction of the shell 1.

[0052] The second chamber 92 of the handle 9 is coaxially arranged with the first chamber 91 of the handle 9. Since the outer diameter of the adjusting member 8 is larger than the outer diameter of the housing 1, the inner diameter of the second chamber 92 of the handle 9 is larger than the first chamber 91, so that the handle 9 can be prevented from falling off from one end of the adjusting member 8. The inner wall of the second chamber 92 of the handle 9 is provided with a second engaging edge engaged with the second edge 12 to prevent the handle 9 and the adjusting member 8 from rotating relative to each other, but the handle 9 can move along the height direction of the adjusting member 8.

[0053] When in use, first move the handle 9 along the end of the shell 1 away from the adjusting member 8, that is, the handle 9 moves upward, so that the handle 9 is separated from the adjusting member 8. At this time, the operator can hold the handle 9 with one hand and rotate the adjusting member 8 with the other hand, so that the transmission shaft 2 and the shell 1 rotate relative to each other. When the rotation is completed, the handle 9 moves along the shell 1 toward one end of the adjusting member 8, that is, the handle 9 moves downward, so that the second chamber 92 of the handle 9 is sleeved with the adjusting member 8, thereby preventing the transmission shaft 2 and the shell 1 from rotating, improving the stability between the transmission shaft 2 and the shell 1, and thereby improving the accuracy of the operator's use.

[0054] Reference Figure 3 In some optional embodiments, a rotary bearing 10 is provided between the transmission shaft 2 and the housing 1. The rotary bearing 10 may be a ball bearing or other bearings, which is not limited in the present application. The provision of the rotary bearing 10 may reduce the friction between the transmission shaft 2 and the housing 1, thereby improving the smoothness of the rotation between the transmission shaft 2 and the housing 1.

[0055] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
