The more specific technical scheme also comprises the following steps: the inner wall of the clamping piece body is a thread matched with the thread rib of the outer wall of the finish rolling deformed steel bar, so that when the clamping piece body is enclosed into a clamping piece, the thread of the inner hole of the clamping piece and the thread rib of the outer wall of the finish rolling deformed steel bar form a threaded connection structure.
Further: the rear end of the clamping piece body is of a step structure, and when the clamping piece body is enclosed into the clamping piece, a round step is formed at the rear end of the clamping piece.
Further: the rear end of the clamping piece body is a sinking platform, and a counter bore is formed at the rear end of the clamping piece when the clamping piece body is enclosed into the clamping piece.
Further: the rear end of the clamping piece body is a conical sinking platform, and when the clamping piece body is enclosed into a clamping piece, a conical counter bore is formed at the rear end of the clamping piece.
The utility model has the advantages that:
1. the threads formed on the inner wall of the clip body are matched with the thread ribs of the finish-rolled deformed steel bar to form clamping of the finish-rolled deformed steel bar, so that the finish-rolled deformed steel bar cannot be damaged;
2. by utilizing the waveform joint surface or the fold-line joint surface at the edge of the clamping piece body, the clamping piece automatically finds the normal clamping position of the clamping piece in the loosening and clamping processes, the dislocation of the clamping piece can not occur, and the clamping and tensioning backing anchor is convenient during tensioning;
3. the clamping piece is made into a wedge-shaped structure, so that automatic wedging and anchoring are facilitated;
4. the clamping piece is manufactured into a step and a counter bore or is additionally provided with a guide sleeve structure, so that the self-installation of the tight spring is facilitated.

Detailed Description
As shown in fig. 1, 2 and 3, the present embodiment includes a structure formed by splicing four clip bodies 2, the outer wall of each clip body 2 is wedge-shaped, the joint of each clip body is a wave joint or a fold-line joint 4, and a wave joint or a fold-line joint is formed when adjacent clip bodies are connected; the inner wall of the clamping piece body 2 is provided with threads 3 matched with the thread ribs on the outer wall of the finish rolling deformed steel bar, so that when the clamping piece body 2 is enclosed into a clamping piece, the threads 3 of the inner hole of the clamping piece and the thread ribs on the outer wall of the finish rolling deformed steel bar form a threaded connection structure; the clip body 2 is manufactured by uniformly processing four wave-shaped grooves on a circular clip blank to form four clip bodies 2 with wave-shaped joint parts or fold-line-shaped joint parts 4.
In the structure shown in fig. 1 and 3, a wave-shaped groove is adopted, so that wave-shaped joint is formed when four clamping pieces with wave-shaped joint parts 4 are connected.
In the structure shown in fig. 4, a fold line groove is used, so that a fold line-shaped joint is formed when the clamping pieces of the four fold line-shaped joint parts 4 are connected.
The rear end of the clip body 2 has the following embodiments:
the first embodiment is as follows:
as shown in fig. 1, 3 and 4, the rear end of the clip body 2 is a step structure, and when the clip body 2 encloses the clip, a circular step 1 is formed at the rear end of the clip.
When the anchor cup is used in the embodiment, the anchor cup 5 is of a structure with a taper hole, and the clamping piece body 2 is of a cone shape matched with the taper hole in a taper manner; one end of the jacking spring 6 is sleeved at the round step of the clamping piece to jack the clamping piece body 2, and the other end of the jacking spring jacks the gland 7.
In an initial state, the jacking spring 6 jacks the clamping piece body 2 to be matched with the wedge-shaped hole of the anchor cup 5, and the clamping piece body 2 clamps the finish-rolled deformed steel bar 8; when the clamping piece body 2 is not required to be wrapped by the finish rolling deformed steel bar 8 in a stretching or moving mode to a required position, the pressing device matched with the clamping piece body 2 pushes the anchor cup to move leftwards, the pressing cover 7 is driven to press the pressing spring 6, and the four clamping piece bodies 2 are loosened.
