The second connecting part 22 is capable of being assembled with the first connecting part 11, so as to connect the connecting body 2 and the fixing base 1. As some embodiments of the present application, the first connecting part 11 and the second connecting part 22 are both formed with threaded holes. A bolt is passed through the threaded hole of the first connecting part 11 and the threaded hole of the second connecting part 22, so as to be fixedly assembled with a nut, thereby connecting the first connecting part 11 and the second connecting part 22. As other embodiments of the present application, one of the first connecting part 11 and the second connecting part 22 can be formed with a clamping groove, and the other of the first connecting part 11 and the second connecting part 22 can be formed with a clamping hook. The clamping hook can be clamped with the clamping groove, so as to be clamped and connected with the first connecting part 11 and the second connecting part 22.

[0052] The connecting body 2 is positionally adjustable along the first direction relative to the fixing base 1, so as to adjust the length of the connecting anchor 10 along the first direction, to improve the adjustment capability of the connecting anchor 10, to meet different use scene requirements, to improve the versatility of the connecting anchor 10, and to meet the use requirements of different customers. As some embodiments of the present application, the first connecting part 11 can be formed with a first matching hole, and the second connecting part 22 can be formed with a plurality of second matching holes. The plurality of second matching holes are sequentially and spacedly arranged along the first direction, and each of the plurality of second matching holes can be matched with the first matching hole. A connecting piece (which can be a bolt) can be passed through the first matching hole and the corresponding second matching hole, so as to connect the first connecting part 11 and the second connecting part 22. The length of the connecting anchor 10 along the first direction can be adjusted by matching the first matching hole with different second matching holes, so as to improve the adjustment capability of the connecting anchor 10.

[0053] The connecting body 2 is formed with a mounting space 21, which can be used to mount the anchor head 3. The mounting space 21 and the anchor head 3 are shaped to be matched with each other. As some embodiments of the present application, as shown in Figure 1 and Figure 2 , the mounting space 21 can be configured as a quadrangular prism shape as shown in Figure 1 , and the anchor head 3 can be configured as a quadrangular prism shape as shown in Figure 2 . The size of the anchor head 3 is smaller than the size of the mounting space 21, so as to facilitate the mounting of the anchor head 3 in the mounting space 21. Figures 3-5 Other shapes of the anchor head 3 are listed in Figure 3 , the anchor head 3 is configured as a cuboid shape, Figure 4 , the anchor head 3 is configured as a circular truncated cone shape, Figure 5The anchor head 3 in the above embodiment is in a cylindrical shape.

The anchor head 3 can be installed in the installation space 21 along a third direction (perpendicular to the first direction), and the part of the cable 20 fixedly connected to the anchor head 3 can be located in the anchor head channel 23. The cross-sectional dimension of the anchor head channel 23 is smaller than that of the anchor head 3, and the cross-sectional dimension of the anchor head channel 23 is larger than that of the cable 20, so that the cable 20 can move relative to the anchor head channel 23 along the first direction, and the anchor head 3 cannot move out of the installation space 21 through the anchor head channel 23. When the connecting anchor 10 is assembled, the operator can place the anchor head 3 in the installation space 21, and the operation of assembling the connecting anchor 10 can be completed. Since the cable 20 needs to be pre-tensioned to be tensioned in actual projects, the anchor head 3 is clamped in the installation space 21 and cannot be moved, and is automatically locked, so that it is self-limited after tensioning, and no additional limiting device is needed, thereby reducing the risk of loosening of the connecting anchor 10 in use, and improving the use reliability of the connecting anchor 10.
