The first bending rod 100 is formed by sequentially connecting a first compression section 110, a second compression section 120 and the first compression section 110, so as to form a semicircular bending rod for fixing an object to be fixed. It should be noted that the structure of the first bending bar 100 is identical to that of the second bending bar 200, and will not be described here.

In some embodiments, the first bending bar 100 and the second bending bar 200 may be comprised of more first compression sections 110 and/or second compression sections 120.

Specifically, the fitting protrusion a is fitted in the fitting groove b, so that the first compression section 110 is ensured to be connected to the second compression section 120, that is, the relative rotation between the first compression section 110 and the second compression section 120 can be prevented, and thus the collapse of the first compression section 110 or the second compression section 120 can be avoided.

In other embodiments, the first end 111 of the first pressing section 110 is provided with an assembling protrusion b extending along the length direction of the first pressing section 110, and both ends of the second pressing section 120 are provided with assembling grooves a extending along the length direction of the second pressing section 120, so that the assembling conditions of the first pressing section 110 and the second pressing section 120 are similar to those described above, and will not be repeated here.

In some embodiments, as shown in fig. 1 and 2, the first pressing section 110 is provided with a first connection hole 112 extending in a thickness direction of the first pressing section 110, and the first connection hole 112 penetrates one of the fitting groove a and the fitting protrusion b; the second pressing section 120 is provided with a second connection hole 121 extending along the thickness direction of the second pressing section 120, and the second connection hole 121 penetrates through the other one of the assembly groove a and the assembly protrusion b, and the second connection hole 121 is matched with the first connection hole 112.

Specifically, the adjusting member 410 is mainly used to adjust the relative position between the first bending bar 100 and the second bending bar 200, thereby fixing the object to be fixed. In addition, the limiting member 420 may serve as a fixing for the position of the adjusting member 410.

In some embodiments, as shown in fig. 1 to 3, the substrate 300 is provided with a stepped hole 330, the aperture of the stepped hole 330 gradually increases in the direction of the first surface 310 toward the second surface 320, and the defining member 420 is a stepped block, which extends into the stepped hole 330 in the direction of the second surface toward the first surface and extends from the first surface, and the stepped block is adapted to the stepped hole 330. Specifically, taking the case that the stepped hole 330 has two steps, the aperture of the stepped hole 330 near the first surface 310 is smaller than the aperture of the second surface 320, when the stepped block extends into the stepped hole 330, the outer steps of the stepped block may abut against the stepped surface of the stepped hole 330, that is, the stepped hole 330 may limit the extending depth of the stepped block, thereby clamping the stepped block in the thickness direction of the substrate 300 to limit the stepped block.

In some embodiments, as shown in fig. 1 to 3, a first fixing hole 340 is formed on a side surface of the substrate 300, an extending direction of the first fixing hole 340 is orthogonal to an extending direction of the stepped hole 330, the first fixing hole 340 penetrates through the stepped hole 330 and extends into the substrate 300, and a second fixing hole 421 adapted to the first fixing hole 340 is formed on the limiting member 420.

In some embodiments, as shown in fig. 1 and 2, the portion of the step block extending beyond the first surface 310 is defined as an extension 422, and the extension 422 is provided with a defining aperture 423 for engaging the adjustment member 410. Specifically, the adjusting member 410 is engaged with the defining hole 423, so that the position of the adjusting member 410 can be defined.

In some embodiments, as shown in fig. 1 and 2, the adjustment member 410 is a screw that is mounted on the defining hole 423 and that cooperates with the first and second curved bars 100 and 200, respectively, on both sides of the defining hole. Specifically, the screw in the present utility model is a positive and negative screw, and when the screw rotates, the first bent rod 100 and the second bent rod 200 are simultaneously moved toward or away from each other.

Specifically, the bearing 440 may ensure that the screw rotates with respect to the defining member 420, so that the distance between the first bent lever 100 and the second bent lever 200 may be adjusted, and at the same time, the bearing 440 may also define the position of the screw, preventing the screw from moving in the first direction. That is, the screw can only rotate and cannot move in position.
