Inside, slip cap 3 is arranged on the inside of body paper refill 4, several T-slots, inclined-plane is provided with the right side inclined-plane of set of books base 1
Convex key 2 is engaged by T-slot with set of books base 1, and compression spring 6 is arranged on the shaft core 8 between set of books base 1 and slip cap 3
On, block 7 is arranged between set of books base 1 and body paper refill 4.
Described inclined-plane convex key 2 is the convex key that several pieces sections are inclined-plane.
The right side of described set of books base 1 is conical protrusions 11, and the centre of set of books base 1 is provided with centre bore 12.
Described slip cap 3 is truncated cone-shaped structure, and the bottom surface of slip cap 3 is provided with cylinder shape groove 31.Compression spring 6
Right side is withstood in cylinder shape groove 31.
Operation principle of the present utility model：Uncompressed state, body paper refill 4 are enclosed on slip cap 3, six inclined convex push-tos
Cross T-slot with expansion set base 1 to coordinate, because the active force of compression spring 6 moves right slip cap 3, make its 6 inclined-plane convex keys
2 along inclined-plane T-slot to axle center linear shrinkage.The displacement of slip cap 3 is by the step hole depth control between screw 5 and expansion set base 1
System.During compressive state, body paper refill 4 is pushed axially slip cap 3 and is moved to the left, and makes its six inclined-plane convex keys 2 along inclined-plane T-slot
Extended to circumferencial direction, the top surface of inclined-plane convex key 2 is fitted close with the inwall of body paper refill 4 and then swelling body paper refill 4
Effect.
The features such as the utility model has self-centering, and high-mechanic is non-maintaining, and easy use is with being not easy to damage inside pipe wall.
Its use reliability is high, and simple to operate, flexible for installation, maintenance and repair is simple, significantly reduces production cost.
