As shown in figure 1, the utility model provides tweezers for clamping titanium meshes, which comprise a connecting part 3, wherein a first handheld part 5 and a second handheld part 6 are connected to the connecting part 3 at the same time, the first handheld part 5 is connected with a first clamping part 1, and the second handheld part 6 is connected with a second clamping part 2. The user holds and presses the first hand-held portion 5 and the second hand-held portion 6 to control the gripping of the first gripping portion 1 and the second gripping portion 2. The first clamping portion 1 is provided with a first notch 11, the second clamping portion 2 is provided with a second notch 21, and as shown in fig. 2, the first notch 11 and the second notch 21 are symmetrically arranged. As shown in figure 3, the first holding part 5 and the second holding part 6 are pressed, so that the first notch 11 and the second notch 21 form a gap 4 capable of accommodating the titanium mesh wire to pass through, and the maximum distance between the gaps 4 is 0.2mm-1 mm. Preferably, the first notch 11 and the second notch 21 are semicircular with a diameter of 0.2mm to 1mm, and the gap 4 formed by the two is circular with a diameter of 0.2mm to 1 mm.

In some embodiments, the distal ends of the first clamping portion 1 and the second clamping portion 2 can penetrate through any two adjacent holes on the titanium mesh so as to clamp the mesh wire of the titanium mesh between the holes, thereby realizing the adjustment of the position of the titanium mesh. The first clamping part 1 and the second clamping part 2 are of a bent structure, and the sight of a user is not affected.

The tweezers of the utility model further comprise a locking device, and after the first clamping part 1 and the second clamping part 2 are clamped, the distance between the first clamping part 1 and the second clamping part 2 is kept unchanged by the locking device. At this time, the user can close the titanium mesh wire in the slit 4 by the slit 4 formed by the first notch 11 and the second notch 21 without pressing the first hand-held part 5 and the second hand-held part 6.

Fig. 3, 4 and 5 show an embodiment of the locking device. In this example, the locking device includes a lock catch 51 connected to the inside of the first hand-held portion 5, a through hole 61 opened in the second hand-held portion 6, and a push lock 62 provided in the second hand-held portion 6. After the first clamping portion 1 and the second clamping portion 2 are clamped, the lock catch 51 can pass through the through hole 61, and then the push lock 62 is pushed to limit the lock catch 51 in the through hole 61.

The lock catch 51 protrudes in the direction of the second hand-held portion 6, and includes a first column 511, a second column 512, and a third column 513 connected in this order from the inside of the first hand-held portion 5 toward the second hand-held portion 6. The diameter of the through hole 61 is larger than the diameters of the second cylinder 512 and the third cylinder 513 and smaller than the diameter of the first cylinder 511, and only the second cylinder 512 and the third cylinder 513 can pass through the through hole 61. The push latch 62 can slide along the surface of the second handle 6. One end of the push lock 62 close to the through hole 61 is provided with a V-shaped opening, and the opening direction points to the through hole 61. The minimum pitch of the V-shaped opening is not larger than the diameter of the second cylinder 512, and the maximum pitch is not smaller than the diameter of the second cylinder 512, so that the second cylinder 512 can sink into the V-shaped opening by pushing the push latch 62 in a direction close to the through hole 61. Since the diameter of the third cylinder 513 is larger than that of the second cylinder 512, after the second cylinder 512 sinks into the V-shaped opening and is limited by the push lock 62, the third cylinder 513 cannot slide out of the through hole 61, and the lock catch 51 is locked in the through hole 61 by the push lock 62. At this time, even if the user does not press the first and second hand-held

portions

5 and 6 any more, the distance between the first and

second sandwiching portions

1 and 2 remains unchanged. After use, the lock 62 is pulled in a direction away from the through hole 61, and the third cylinder 513 is no longer restricted, slides out of the through hole 61, and is unlocked.

In some embodiments, the first and

second handles

5, 6 are provided with anti-slip lines on the outside to prevent the forceps from slipping off the user's hand. In the embodiment with the push lock 62, the outer side of the push lock 62 is provided with anti-slip lines to increase the friction force when the user pushes the push lock 62, so as to lock the forceps in the holding state.

In summary, according to the forceps for holding the titanium mesh provided by the utility model, the first notch and the second notch are respectively arranged on the first holding portion and the second holding portion to form a gap capable of accommodating the titanium mesh wire to pass through, when the position of the titanium mesh implanted into the eye orbit needs to be adjusted, the forceps are used for holding the titanium mesh from one side of the titanium mesh through any two adjacent holes on the titanium mesh, so as to clamp the connecting part between the holes, and the position of the titanium mesh is adjusted by means of the forceps. The utility model is suitable for small spaces such as eye sockets and the like, is particularly suitable for scenes in which the titanium mesh cannot be clamped from two sides, and can finely adjust any part of the titanium mesh in the small space.
