[0006] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable vaginal speculum, comprising an upper speculum and a lower speculum. A first handle is fixed on the upper speculum, and a second handle is fixed on the lower speculum. The first handle has a perforation hole. The second handle is rotatably connected to the first handle. A sliding groove is formed inside the first handle. A gear is rotatably connected to the middle position of the sliding groove. Two L-shaped sliders are slidably connected within the sliding groove. The two L-shaped sliders are centrally symmetrically distributed. A toothed rail is fixed on the side of each L-shaped slider near the gear, and the toothed rail meshes with the gear. The first handle has spring grooves on both sides of the sliding groove, which are connected to the sliding groove. A first spring is fixed in the spring groove, and the other end of the first spring is fixed to an L-shaped slider. A locking post is fixed to the outer end of the L-shaped slider. The second handle has positioning plates fixed on both sides of the first handle. The positioning plates have multiple locking slots. The locking post passes through the first handle and engages with the locking slots. The first handle has a through groove, and an operating block is slidably connected to the first handle. The operating block passes through the through groove and is fixedly connected to one of the L-shaped sliders. The operating block is slidably connected to the through groove.

[0007] Furthermore, an improvement of this utility model is that the size of the operating block is set to be larger than the size of the through slot.

[0008] Furthermore, the present invention is improved in that two limiting rods are fixed inside the sliding groove, and the limiting rods pass through the L-shaped slider and are slidably connected to it.

[0009] Furthermore, the present invention is improved by providing anti-slip textures on the operating block, the first handle, and the second handle.

[0010] Furthermore, an improvement of this utility model is that both the upper and lower expansion plates are made of transparent material.

[0011] Furthermore, an improvement of this utility model is that the positioning plate and the second handle are configured as a single unit.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides an easily adjustable vaginal speculum, which has the following beneficial effects:

[0014] This easily adjustable vaginal speculum, through a gear and toothed rail linkage mechanism combined with a first spring reset function, enables single-finger pressing and sliding operation of the operating block to control the extension and retraction of the two locking posts and their engagement and disengagement with the locking slots, thereby achieving adjustment and fixation of the vaginal speculum. Compared with the traditional screw adjustment method, the operation steps are simplified from two-handed turning to single-handed pressing and sliding, avoiding cumbersome operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 An adjustable vaginal speculum includes an upper speculum 1 and a lower speculum 2. A first handle 3 is fixed to the upper speculum 1, and a second handle 4 is fixed to the lower speculum 2. The first handle 3 has a perforation 5. The second handle 4 is rotatably connected to the first handle 3. A sliding groove 6 is formed inside the first handle 3. A gear 7 is rotatably connected to the middle position of the sliding groove 6. Two L-shaped sliders 8 are slidably connected inside the sliding groove 6. The two L-shaped sliders 8 are centrally symmetrically distributed. A toothed rail 9 is fixed on the side of the L-shaped slider 8 near the gear 7. The toothed rail 9 meshes with the gear 7. Spring grooves 1 are formed on both sides of the sliding groove 6 inside the first handle 3. 0. The spring groove 10 is connected to the sliding groove 6. A first spring 11 is fixed in the spring groove 10. The other end of the first spring 11 is fixed to the L-shaped slider 8. A locking post 12 is fixed on the outer end of the L-shaped slider 8. Positioning plates 13 are fixed on both sides of the first handle 3 on the second handle 4. Multiple locking slots 14 are opened on the positioning plates 13. The locking post 12 passes through the first handle 3 and engages with the locking slots 14. A through groove 15 is opened on the first handle 3. An operating block 16 is slidably connected to the first handle 3. The operating block 16 passes through the through groove 15 and is fixedly connected to one of the L-shaped sliders 8. The operating block 16 is slidably connected to the through groove 15.

[0022] When using this device, by holding the first handle 3 and the second handle 4 with one hand to separate the upper expansion piece 1 and the lower expansion piece 2, a single finger contacts the operating block 16 and moves it laterally. The operating block 16 drives the L-shaped slider 8 on one side to move along the sliding groove 6 towards the center. The L-shaped slider 8 drives the locking pin 12 to move inward, and the locking pin 12 disengages from the locking groove 14. At this time, the first spring 11 is stretched. When the L-shaped slider 8 on one side moves, it drives the toothed rail 9 above it to move. The toothed rail 9 meshes with the gear 7, thereby causing the gear 7 to rotate. The gear 7 and... Another gear 9 engages, thereby driving the other gear 9 and the L-shaped slider 8 to move towards the center along the sliding groove 6. On the same principle, the other locking pin 12 disengages from the slot 14. Pressing the two first handles 3 and the second handle 4 with one hand brings them closer together, separating the upper expansion piece 1 and the lower expansion piece 2. Once separated to the designated position, the operating block 16 is released, and the first spring 11 releases potential energy, driving the L-shaped slider 8 to move outward. The locking pin 12 engages with the corresponding slot 14, thus fixing the relative positions of the first handle 3 and the second handle 4.

[0023] In actual use, it was found that in order to prevent the operating block 16 from colliding with the through groove 15, in this embodiment, the size of the operating block 16 is set to be larger than the size of the through groove 15.

[0024] In actual use, it was found that in order to make the L-shaped slider 8 more stable when moving, in this embodiment, two limiting rods 17 are fixed in the sliding groove 6. The limiting rods 17 pass through the L-shaped slider 8 and are slidably connected to it.

[0025] In actual use, it was found that in order to avoid slippage when contacting the operating block 16, the first handle 3 and the second handle 4, in this embodiment, the operating block 16, the first handle 3 and the second handle 4 are all provided with anti-slip textures.

[0026] In actual use, it was found that, further, in this embodiment, both the upper expansion piece 1 and the lower expansion piece 2 are made of transparent material.

[0027] In actual use, it was found that in order to improve structural strength, in this embodiment, the positioning plate 13 and the second handle 4 are set as a whole.
