The technical solution adopted in the utility model is：A kind of segmented large deformation pressure-relieving achor bar, including second body of rod and one
Individual or multiple first bodies of rod；First body of rod and second body of rod connect into an anchor pole, and second body of rod is located at the front end of anchor pole, the second bar
The rear end of body is provided with screw thread, and the two ends of first body of rod are respectively equipped with screw thread, between first body of rod and second body of rod and adjacent the
By allowing pressure device to connect between one body of rod；Described allows pressure device to include metal sleeve, described metal sleeve two ends difference
It is sleeved on two first bodies of rod being connected or on first body of rod and second body of rod, first body of rod and second body of rod in metal sleeve
End is respectively equipped with spring, metal baffle and nut, and spring is placed between metal baffle and sleeve, and metal baffle is solid by nut
It is fixed.
In above-mentioned segmented large deformation pressure-relieving achor bar, the front end of the second described body of rod is in claw type.
In above-mentioned segmented large deformation pressure-relieving achor bar, also set respectively on first body of rod and second body of rod in described sleeve
There is spring backing plate, spring backing plate is positioned by the end of sleeve, and spring is located between metal baffle and spring backing plate.
In above-mentioned segmented large deformation pressure-relieving achor bar, the tail end for the anchor pole that described first body of rod and second body of rod is linked to be
Provided with nut, backing plate and pallet.
