[0010] A tensioning rack is installed in each of the two tensioning guide rails. One tensioning rack meshes with the tensioning gear on one lateral side, and the other tensioning rack meshes with the tensioning gear on the other lateral side. The rotation of the tensioning gear can drive the two tensioning racks to telescope in the longitudinal direction at the same time.

[0011] The longitudinal rear end of one tensioning rack extending out of the locking shell is fixedly connected to a clamping mechanism, and the longitudinal front end of the other tensioning rack extending out of the locking shell is fixedly connected to another clamping mechanism.

[0012] A hexagonal rotating head is arranged on the top end of the gear shaft.

[0013] The clamping mechanism comprises a clamping outer ring, the central axis of which is arranged vertically, the clamping outer ring is fixedly connected to the tensioning rack, and a clamping inner ring is sleeved inside each clamping outer ring.

Figure 3 As shown, the locking shell 1 includes a shell 101 with an open bottom surface and two lateral side walls, and longitudinally arranged tensioning guide rails 102 are respectively provided on the two longitudinal inner walls of the shell 101. The cavity between the two tensioning guide rails 102 is a tensioning gear installation cavity 103, and the tensioning gear installation cavity 103 is connected to the two tensioning guide rails 102; a through gear shaft rotation hole 104 is vertically opened on the top surface of the shell 101.

[0034] like Figure 2As shown, a tensioning gear 2 is installed in the tensioning gear installation cavity 103, and the bottom end of the gear shaft 3 is vertically fixed on the tensioning gear 2. The top end of the gear shaft 3 extends through the gear shaft rotating hole 104 to the upper part of the top surface of the shell 101. A locking nut 4 is threadedly mounted on the gear shaft 3 on the upper part of the top surface of the shell 101, and the locking nut 4 can lock the gear shaft 3 and the locking shell 1.

[0035] like Figure 2 and Figure 4 As shown, a tensioning rack 5 is installed in each of the two tensioning guide rails 102. One tensioning rack 5 is meshed with the tensioning gear 2 on one lateral side, and the other tensioning rack 5 is meshed with the tensioning gear 2 on the other lateral side. The rotation of the tensioning gear 2 can drive the two tensioning racks 5 to telescope in the longitudinal direction at the same time.

[0036] like Figure 2 and Figure 4 As shown, a tensioning rack 5 extends out of the locking shell 1 and its rear longitudinal end is fixedly connected to a clamping mechanism 6 , and another tensioning rack 5 extends out of the locking shell 1 and its front longitudinal end is fixedly connected to another clamping mechanism 6 .

[0037] As a preferred solution of this embodiment, Figure 2 As shown, the clamping mechanism 6 includes a clamping outer ring 601 , the central axis of the clamping outer ring 601 is vertically arranged, the clamping outer ring 601 is fixedly connected to the tensioning rack 5 , and a clamping inner ring 602 is sleeved inside each clamping outer ring 601 .

[0038] like Figure 5 As shown, the clamping inner ring 602 includes an integrally formed circular portion 60201 and a frustum ring portion 60202, the circular portion 60201 and the frustum ring portion 60202 are coaxially arranged, and the top of the frustum of the frustum ring portion 60202 is connected to the bottom of the circular portion 60201; the cylinder wall thickness of the circular portion 60201 is equal, and the cylinder wall thickness of the frustum ring portion 60202 gradually increases from the top of the cone to the bottom of the cone.

[0039] like Figure 5 As shown, a contraction seam 60203 penetrating the circular portion 60201 and the frustum ring portion 60202 is provided on the side wall of the clamping inner ring 602 .
