Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber cutters, in particular to an optical fiber cutter with adjustable cutting blade height. Background Art

[0002] A fiber optic cutter is a professional tool mainly used for cutting and processing optical fibers. It is widely used in optical fiber communications, optical fiber sensing, optical fiber lasers and other fields. It is an indispensable equipment in the process of optical fiber processing and connection.

[0003] When using the fiber optic cutter in the prior art, the optical fiber is first placed in the pressing groove, and the bare optical fiber is placed straight in the pressing groove. Then the pressing plate is closed, and the slider with a blade is pushed to make the blade cut the lower surface of the optical fiber and slide freely to the other side to cut the optical fiber. When it is found that the blade is rolled and the optical fiber cannot be cut neatly, it is often necessary to adjust the blade height so that the place where the blade is not used can be cut to ensure the subsequent cutting quality. However, when adjusting the cutting device in the entire prior art, such as the Chinese patent application No. 202122975181.8, a fiber optic cutter uses a screw to rotate to adjust the height of the cutting blade during use, but the overall adjustment cannot accurately determine the height of the cutting blade, and the adjustment position is not intuitive enough. It is more troublesome to control the specific position of the cutting blade, and the blade replacement is more troublesome. Therefore, an improved fiber optic cutter with adjustable cutting blade height is needed to address this problem. Utility Model Content

[0004] The purpose of the present utility model is to provide a fiber optic cutter with adjustable cutting blade height to solve the problems raised in the above background technology.

[0006] Preferably, a screw is movably provided inside the second slide groove through a bearing, and the adjusting block is movably sleeved on the outer surface of the screw through a thread. The screw is rotated to drive the adjusting block to move up and down inside the second slide groove, thereby adjusting the height position of the cutting knife, and the entire adjustment process is clearly visible, which makes it convenient to observe the adjustment of the blade so that the position of the curling blade is away from the cutting position, thereby facilitating subsequent optical fiber cutting work.

[0007] Preferably, a twisting block is fixedly provided at one end of the screw rod, and the screw rod can be easily rotated by the twisting block.

[0008] Preferably, a driving handle is movably provided on one side of the surface of the fixed plate through a rotating shaft, a driving groove is provided on the outer surface of the driving handle, and a driving column is movably provided on the outer surface of the upper end of the movable warehouse through a bearing, and the driving groove is movably engaged with the outer surface of the driving column.

In this way, the cutting knife of the present device can be replaced quickly and conveniently, so that it is easy to use.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. With the use of the device, the position where the cutting knife is involved in cutting for a long time will gradually curl, resulting in uneven cutting. At this time, the screw can be rotated to drive the adjustment block to move up and down inside the second slide groove, so that the height position of the cutting knife can be adjusted. The entire adjustment process is clearly visible, and the adjustment of the blade can be easily observed, so that the position of the curled blade is away from the cutting position, thereby facilitating subsequent optical fiber cutting work.

[0013] 2. When the utility model is used, a relatively slender tool such as a screwdriver can be easily passed through the through slot, and then the card block is pushed to shrink the telescopic rod, and finally the card block and the card slot are misaligned. At this time, the cutting knife can be removed, and then the cutting knife can be changed to use the other side, so that the side of the cutting knife that has not been involved in cutting can be turned to participate in cutting, or a new cutting knife can be replaced. In this way, the cutting knife of the device can be replaced quickly and conveniently, so that it is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] A screw rod 11 is movably provided inside the second chute 4 via a bearing, and the adjusting block 5 is movably sleeved on the outer surface of the screw rod 11 via a thread. The screw rod 11 is rotated to drive the adjusting block 5 to move up and down inside the second chute 4, thereby adjusting the height position of the cutting blade 8. The entire adjustment process is clearly visible, and the adjustment of the blade can be easily observed, so that the position of the curling blade is away from the cutting position, thereby facilitating the subsequent optical fiber cutting work.

[0023] A twisting block 12 is fixedly provided at one end of the screw rod 11, and the screw rod 11 can be easily rotated by twisting the block 12;

[0024] A driving handle 13 is movably provided on one side of the surface of the fixed plate 1 through a rotating shaft, and a driving groove 14 is provided on the outer surface of the driving handle 13. A driving column 15 is movably provided on the outer surface of the upper end of the movable chamber 3 through a bearing. The driving groove 14 is movably engaged with the outer surface of the driving column 15. By rotating the driving handle 13 through the rotating shaft, the movable chamber 3 and the cutting knife 8 can be forced to move along the first sliding groove 2 toward the insertion hole 10 through the driving groove 14 and the driving column 15. At this time, the optical fiber inserted into the insertion hole 10 can be quickly cut off by the cutting knife 8;
