[0002] The fiber needs to be fixed when coupling, and the fiber steel pipe needs to be fixed and the fiber needs to be stretched well during fixing. At present, two metal sheets are generally held by hand to clamp, which can meet certain use requirements, but has great defects, such as unfirm fixing, easy shaking, poor position accuracy, unsatisfactory coupling effect, low yield, low operation efficiency, high labor intensity, high labor cost and inability to effectively meet use requirements.

[0003] The utility model solves the technical problem to provide a fiber coupling chuck which is firm and reliable in fixing, high in position accuracy, good in coupling effect, high in yield, high in operation efficiency, low in labor intensity, low in labor cost and effective in meeting use requirements. SUMMARY

[0004] To solve the problems of the prior art, such as unfirm fixing, easy shaking, poor position accuracy, unsatisfactory coupling effect, low yield, low operation efficiency, high labor intensity, high labor cost and inability to effectively meet use requirements, the utility model adopts the following technical scheme.

[0005] The utility model provides a fiber coupling chuck, which comprises a circular seat, a cylindrical clamping section and a fastening screw, the cylindrical clamping section is arranged on the circular seat, a semicircular fiber steel pipe placing groove is arranged at the middle of the head of the cylindrical clamping section, a threaded hole is arranged at the side of the head, an h-shaped three-section fiber stretching step is arranged at the front, a fiber accommodating slot is arranged in the middle of the circular seat, and the fastening screw is screwed into the top of the fiber steel pipe placing groove from the threaded hole of the cylindrical clamping section.

[0006] The utility model has the advantages that the fiber is placed in the semicircular groove and the fiber steel pipe fastened by the screw, the three-section stretching step and the accommodating slot, the fiber is firm and reliable in fixing, high in position accuracy, good in coupling effect, high in yield, high in operation efficiency, low in labor intensity, low in labor cost and effective in meeting use requirements. BRIEF DESCRIPTION OF DRAWINGS

[0007] Figure 1 It is a structural schematic view of an embodiment of the utility model.

[0008] Figure 2 It is a top view structural schematic view.

[0009] Figure 3 It is a front view structural schematic view. DETAILED DESCRIPTION

[0010] The preferred embodiments of the utility model will be described in detail below in combination with the drawings.

[0011] Please refer to Figure 1 A fiber coupling chuck, including circular seat 1, cylindrical clamping section 2 and fastening screw 3, cylindrical clamping section 2 is arranged on circular seat 1, the middle part of the head of cylindrical clamping section 2 is equipped with semicircular fiber steel pipe placing groove 21, the side of head is equipped with threaded hole 22, the front is equipped with h type three section type fiber stretching step 23, the middle part of circular seat 1 is equipped with fiber accommodation slot 11, fastening screw 3 is screwed into the top of fiber steel pipe placing groove 21 from the threaded hole 23 of cylindrical clamping section 2, when operating, the steel pipe of fiber is placed in semicircular placing groove, screw is screwed from outside to inside (as shown in Figure 3 ), so the steel pipe can be fixed, fiber is stretched through three section type stretching step and finally rests in accommodation slot (as shown in Figure 2 ), so fiber is fixed very well, and fiber tail will not break.

[0012] The utility model has the advantages that fiber is placed through semicircular groove and screw fastening steel pipe, three section stretching step and accommodation slot, fiber is fixed firmly and reliably, position precision is high, coupling effect is good, good product rate is high, operation efficiency is high, labor intensity is small, artificial cost is low, effectively satisfy use requirement.

[0013] The above embodiments and drawings are not limited to the product shape and style of the utility model, and any ordinary skilled person in the art can make appropriate changes or modifications, which should be considered as not departing from the patent scope of the utility model.
