[0038] In some embodiments, the hook member 30 is configured as an elastic member. When the hook member 30 contacts the eyelid, the hook member 30 can undergo appropriate elastic deformation, so that the hook member 30 can better open the eyelid and avoid damage to the eyelid. The hook member 30 is configured as a plate-like structure, so that the hook member 30 can cover the eyelashes when hanging the eyelid, preventing the eyelashes from extending to the eyeball, thereby facilitating the user's subsequent operation on the eyeball.

[0039] The hook member 30 includes a connecting portion 31, a bending portion 32 and a contact portion 33. The connecting portion 31 is connected to the connecting rod 20. The bending portion 32 is connected to a side of the connecting portion 31 away from the connecting rod 20, and is bent relative to the connecting portion 31 in a direction away from the other connecting rod 20. The bending portion 32 is bent in a roughly "C" shape. The bending portions 32 in the two hook members 30 are bent in opposite directions. The bending portions 32 in the two hook members 30 are located on the same side of the eyelid opener 100. The contact portion 33 is connected to a side of the bending portion 32 away from the connecting portion 31. In some embodiments, the bending portion 32 is configured as an elastic structure, and the bending portion 32 can be elastically bent relative to the connecting portion 31.

[0040] The width D1 of the contact portion 33 along the extension direction of the connecting rod 20 is 2mm-4mm. Among them, the extension direction of the connecting rod 20 is the length direction of the connecting rod 20. In the embodiment of the present application, the eyelid opener 100 can be suitable for mouse pups, such as pups that are 10-20 days old. The eyeballs and palpebral fissures of pups are relatively small, and the size of existing eyelid openers is too large to be suitable for pups. The width D1 of the contact portion 33 in the present application is set to 2mm-4mm, and the width of the contact portion 33 can well match the eyelids of pups. Exemplarily, the width D1 of the contact portion 33 can be 2mm, 2.2mm, 2.4mm, 2.5mm, 2.6mm, 2.8mm, 3mm, 3.5mm, 4mm, and the like.

[0041] When the hook member 30 opens the eyelid of the mouse, the contact portion 33 can extend under the eyelid of the mouse, and the eyelid of the mouse is located between the contact portion 33 and the connecting portion 31. The thickness C1 of the contact portion 33 is 0.3mm-1mm. For example, the thickness C1 of the contact portion 33 can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc. Since the eyelid of the mouse is very thin, the thickness C1 of the contact portion 33 in the embodiment of the present application is set to 0.3mm-1mm to avoid the contact portion 33 from causing damage to the eye of the mouse. The spacing H1 between the connecting portion 31 and the contact portion 33 is 0.5 mm to 2 mm, so that when the hook member 30 opens the eyelids of the mouse, the eyelids of the mouse can be accommodated between the connecting portion 31 and the contact portion 33, and there will not be too much space between the connecting portion 31 and the contact portion 33, so that it is convenient for the user to use the hook member 30 to open the eyelids of the mouse, and the convenience of using the eyelid opener 100 is improved. For example, the spacing H1 can be 0.5 mm, 0.6 mm, 1 mm, 1.2 mm, 1.5 mm, 2 mm, etc.

[0042] In some embodiments, the width D1, thickness C1, and spacing H1 between the contact portion 33 and the connecting portion 31 of the hook member 30 can also be specifically set according to actual needs, and are not specifically limited in this application. For example, the width D1, thickness C1, and spacing H1 between the contact portion 33 and the connecting portion 31 can also be adapted to objects with larger eye sizes, such as rats and rabbits, so that the eyelid opener 100 can be suitable for objects with larger eye sizes.

[0043] In some embodiments, the hook member 30 has a silicone structure so that the hook member 30 can better fit the eyelid and prevent the hook member 30 from damaging the eyelid and the eyeball. In some embodiments, the hook member 30 is detachably connected to the connecting rod 20 so that the hook member 30 can be replaced after the eyelid opener 100 is used, or when the hook member 30 is damaged, so as to reduce the use cost of the eyelid opener 100.

[0044] See also Figure 4 In some embodiments, the eyelid opener 100 further includes a scale structure 61 and a pointer 62 structure, wherein the scale structure 61 is disposed on one of the connecting rods 20, and the pointer 62 structure is disposed on the other connecting rod 20. A scale is disposed on the scale structure 61. When the two connecting rods 20 rotate relative to each other, the pointer 62 is used to indicate the scale on the scale structure 61, so that the user can intuitively determine the opening angle between the two connecting rods 20.

[0045] In some embodiments, the scale structure 61 is disposed on the adjusting member 41, and the pointer 62 is disposed on the fixing member 10 at a position corresponding to the scale structure 61. The scale structure 61 is provided with a scale for indicating the opening angle between the two connecting rods 20, and the scale on the scale structure 61 corresponds to the extension length of the adjusting portion 412. When the adjusting portion 412 rotates, the pointer 62 is used to indicate the scale on the scale structure 61.

[0046] See also Figure 5 In some embodiments, the eyelid opener 100 further includes a reset member 70, the two ends of which are respectively connected to the two connecting rods 20, or the two ends of which are respectively connected to the two supporting rods 42. The reset member 70 is used to maintain tension between the two connecting rods 20 or the two supporting rods 42, so that the opening angle between the two connecting rods 20 remains stable. The tensioning force provided by the reset member 70 can keep the external thread structure of the adjustment member 41 and the internal thread structure of the through hole 11 in contact with each other, and the friction between the internal thread structure and the external thread structure can effectively prevent the adjustment member 41 from rotating due to external interference, and prevent the external interference from causing the opening angle between the two connecting rods 20 to change, thereby improving the structural stability of the eyelid opener 100 when in use. Among them, the reset member 70 can be configured as a coil spring, a torsion spring, an elastic band, etc.
