Among the figure, 1, U-shaped deck, 2, clamping screw, 3, RECOIL INSERTS, 4, end cap, 5, sealing block, 6, sealed rubber, 7, the sheath screw, 8, end cap screw, 9, U-groove bevel, 10, sheath installs tapped hole, 11, matching hole, 12, screw rod assembling screw thread, 13, sheath installs unthreaded hole, 14, half-arc groove, 15, end cap installs unthreaded hole, 16, the bulb groove, 17, end cap is installed tapped hole, and 18, the sealed rubber mounting groove, 19, pressing handle.

Embodiment

Among Fig. 1, the lower shoe of U-shaped deck 1 is provided with the U-groove bevel suitable with the tube wall external diameter, is used for blocking product pipe walls during use.The upper plate of U-shaped deck 1 is provided with for the RECOIL INSERTS 3 that clamping screw 2 is installed, and RECOIL INSERTS 3 is loaded on the upper plate of U-shaped deck 1 through sheath screw 7.Clamping screw 2 links to each other the sealing block 5 that itself and end face are equipped with sealed rubber 6 by two semicircle end caps 4 and a plurality of end cap screws 8 again.

Among Fig. 2, U-shaped deck 1 is comprised of lower shoe, upper plate, dunnage, and lower shoe is provided with U-groove bevel 9; Upper plate is provided with matching hole 11 and sheath is installed tapped hole 10, is used for installing RECOIL INSERTS.Matching hole 11 and U-groove bevel 9 are coaxial.

Among Fig. 3, an end of clamping screw 2 is designed to bulb-type, be used for and sealing block on the bulb groove cooperate, play the effect of automatic adjustment direction; The other end welding pressing handle 19.
