When needed, the steel arch can be abutted to other structures by lifting the adjusting screw rod 2, and the steel arch is kept at the position by self-locking of the threads.

Example 2:

on the basis of the above embodiments, in the present embodiment, the adjusting handle 31 is connected to the adjusting nut 3. Through setting up adjusting handle 31, be convenient for rotate adjusting nut 3 through adjusting handle 31 for the operation is convenient and fast more.

Example 3:

as shown in fig. 2, on the basis of the above embodiment, in this embodiment, an inclined strut 6 is disposed between the slot 1 and the adjusting screw 2. Utilize bracing 6 can play the effect of support to draw-in groove 1, be favorable to improving the stability and the rigidity of draw-in groove 1, avoid draw-in groove 1 to take place the slope under the effect of external force and influence the position accuracy of steel bow member.

In this embodiment, the two inclined struts 6 are symmetrically distributed on two sides of the adjusting screw rod 2. Two inclined struts 6 are symmetrically distributed on two sides of the adjusting screw rod 2, so that stress balance of the clamping groove 1 is facilitated, and the supporting effect of the inclined struts 6 on the clamping groove 1 is enhanced.
