when the shearable optical fiber needle is adopted, the shearable optical fiber needle extends out through the pen point, and the extending part length of the shearable optical fiber needle is adjusted by moving the shell; when the disposable optical fiber needle is adopted, the pen point is detached, and the disposable optical fiber needle is directly sleeved at the head end of the laser handle.

The laser handle comprises a handle main body and a handle seat, and the screw rod sleeve is fixedly sleeved on the handle main body of the laser handle.

The screw rod cover includes the screw rod portion of front end and the polished rod portion of rear end, the casing is including the preceding casing and the back casing that link firmly together, wherein preceding casing with the screw rod portion screw thread fit of screw rod cover front end, back casing cover is located on the polished rod portion.

The nib is provided with an optical fiber needle sleeve.

The invention has the advantages and positive effects that:

1. the invention is applicable to disposable optical fiber needles and shearable optical fiber needles, and is simple and convenient to replace.

2. The outer part of the optical fiber connected with the tail part of the handle seat can be protected by adopting the PVC armor tube, so that the defect that the bare optical fiber is easy to break can be avoided.

Drawings

Figure 1 is a schematic view of the present invention employing a shearable optical fiber needle,

fig. 2 is a schematic view of the present invention employing a disposable fiber optic needle.

The optical fiber needle comprises a fiber needle sleeve 1, a pen point 2, a shearable fiber needle 3, a shell 4, a front shell 41, a rear shell 42, a screw sleeve 5, a screw part 51, a polish rod part 52, a cut-off fiber needle sleeve 6, a laser handle 7, a handle seat 71, a handle main body 72, a disposable fiber needle 8 and a disposable fiber needle sleeve 81.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings.

As shown in fig. 1-2, the invention comprises a laser handle 7, a screw sleeve 5, a shell 4 and a pen point 2, wherein the laser handle 7 comprises a handle main body 72 and a handle seat 71, the screw sleeve 5 is fixedly sleeved on the handle main body 72, the shell 4 is sleeved on the screw sleeve 5, the shell 4 is screwed, the shell 4 can move along the screw sleeve 5, the pen point 2 is detachably arranged at the front end of the shell 4, and the pen point 2 is provided with an optical fiber needle sleeve 1. In this embodiment, the rear end of the nib 2 is in threaded connection with the front end of the housing 4, and the nib 2 can be detached by screwing the nib 2.

As shown in fig. 1, the screw sleeve 5 includes a screw portion 51 at the front end and a polish rod portion 52 with the rear end abutting against the handle seat 71, the housing 4 includes a front housing 41 and a rear housing 42 screwed together, wherein the front housing 41 is screwed with the screw portion 51 at the front end of the screw sleeve 5, the rear housing 42 is sleeved on the polish rod portion 52, the front housing 41 is screwed, even if the front housing 41 and the rear housing 42 move together, and the rear housing 42 ensures that the screw sleeve 5 inside cannot be exposed.

The working principle of the invention is as follows:

when the shearable optical fiber needle 3 is adopted, as shown in fig. 1, the pen point 2 is firstly dismounted, the shell 4 is screwed to move backwards to expose the head end of the handle main body 72 of the laser handle 7, then the shearable optical fiber needle sleeve 6 is connected with the head end of the handle main body 72, the shearable optical fiber needle 3 is penetrated out of the optical fiber needle sleeve 1 on the pen point 2, then the pen point 2 is remounted on the shell 4, the shell 4 is screwed to move forwards to a proper position, the shearable optical fiber needle 3 is exposed for a certain length and begins to be cut along with the use, when the shearable optical fiber needle 3 is insufficient in exposed length, the shell 4 is screwed to move backwards to expose a section of shearable optical fiber needle 3 again, and the shearable optical fiber needle 3 continues to be cut along with the use, and only the shell 4 moves in the whole process, and the shearable optical fiber needle 3 does not move along with the use.
