As shown in fig. 1, the packing tube comprises a base 1 and a middle core which are detachably connected, wherein the middle core comprises a fork 2, a bead 3 containing paste, and a spiral 4 driving the bead 3 to slide relative to the fork 2. The inner wall of the fork 2 is provided with a clamping groove 21, and the clamping groove 21 can penetrate through the pipe wall of the fork 2 or can not penetrate through the pipe wall of the fork 2. The beads 3 are provided with elastic claws 31 matched with the clamping grooves 21; the base 1 is provided with an unlocking part 11, the unlocking part 11 triggers the elastic clamping jaws 31 to deform and separate from the clamping grooves 21 when the base 1 and the middle bundle core are in a combined state, at the moment, the elastic clamping jaws 31 do not play a limiting role, and the axial height of the beads 3 can be adjusted by relatively rotating the spiral 4 and the fork 2.

Under the separation state of the base 1 and the middle bundle core, the elastic claw 31 is matched with the clamping groove 21 to limit the axial relative positions of the bead and the fork, and the axial height of the bead 3 cannot be adjusted through relatively rotating the spiral 4 and the fork 2. The periphery of the spiral 4 is sleeved and fixed with a middle beam 5.

As shown in fig. 5, when the lock is unlocked and used, the elastic claw 31 is pressed against the inner wall of the bead 3 by elasticity, so as to provide the torque force required by the user.

As shown in fig. 2, 3, and 4, the elastic claw 31 includes an elastic piece 311 and a collet 312. At least one end of the elastic piece 311 is connected with the bead 3, and the unlocking part 11 is matched with the elastic piece 311; the clip 312 is connected to the elastic piece 311 and is engaged with the slot 21.

The beads 3 are cylindrical, and the walls of the beads 3 are provided with hollow-out areas 313 allowing the elastic claws 31 to sink into the cylinder. When the beads 3 are loaded into the fork 2, the elastic claw 31 can be radially retracted into the hollow-out area 313, so that the frictional resistance between the elastic claw 31 and the fork 2 is reduced, and the assembly is facilitated.

In order to prevent the elastic claw 31 from being excessively deformed during the assembly or use of the product, as shown in fig. 3, the elastic piece 311 is connected to the inner edge of the corresponding side of the hollow 313 at both ends of the packing tube in the axial direction, and the clamp 312 is located at the middle of the elastic piece 311 in the axial direction of the packing tube.
