The block 70 is formed by a bump of a ring train, and the claw portion 63 is formed with a fitting 72 so as to fit the cone. The tapered movable pressing block 70 may be provided with an elastic top support member 'intended to be disposed, and the predetermined portion of the body 40 when the rest portion 73 and the upper elastic claw portion 63 are in a relaxed state; The assembly is disposed on the convex cylinder body 4 〇 the outward expansion actuator 6 〇 the inner circumference of the bidirectional expansion actuator 60 defines the lower tapered edge portion 620 and the upper end of the bidirectional expansion actuator 60 defines the upper tapered edge portion 63由; the central one screw hole 71 is screwed into the type movable pressing block 70. The top end of the limiting actuating member 60 is incapable of tightening the block 70. The tapered guide portion 73 can be inclined with the 630 to the top end of the mating shape 41 and The limiting portion 72, which can be provided with a nut, can be used for the bidirectional expansion actuator 6 to define the bottom groove 64, so that the convex-shaped movable pressing block 70 can reach the bottom end and the two-way limit. Expanding the actuating member 80, the elastic top strut member 8b can be used to make the tapered beading edge portion 630 of the tapered movable pressing block abut each other. The elastic top strut member 80 is used to ensure the tapered movable block 70. The top is returned to the original position, so that the tapered edge portions 630 are stuck to each other and cannot be loosened. The tapered angle of the tapered edge portion 63 of the tapered guide 63 of the compact block 7 may be completed, or as shown in FIG. 6, the tapered movable tapered angle is smaller than the upper elastic claw portion 63. A combination of the angle gaps W is formed between the upper cones. With the above structure and composition design, the following is a description of the use of the Lu Shi example: as shown in Figure 4 (and please cooperate with the first and second expansion actuators 60 to be inside the main pole 1〇, The bottom support rod assembly portion 31 is inserted into the support rod 2, so that when the rod 20 is rotated, the rotary sleeve % and the thread portion 41 provided by the cone 40 are synchronously rotated. The screw hole 71 of the 70 is screwed, but the tapered jaw is located in the bidirectional expansion actuator 60 and is not rotatable, and the axial displacement of the segment 41. As shown in Fig. 5, • when rotating in the reverse direction (as shown in the figure) In terms of the surface, the state of the axial displacement is driven. At this time, the tapered seat portion 5 is more tightly pressed toward the bottom end of the expansion actuator 60, and the lower elastic claw portion is further tightened. The positioning state of the inner wall of the rod 10; on the other hand, as the upward displacement, the cone-shaped movable pressing block 70 is closer to the spacing, so that the cone-shaped movable 73 and the bi-directional expansion actuator 6 The elastic claw portion is provided to stop the cone guide portion 73 and the upper shape. The portion 73 is the same as the upper elastic claw portion. The edge portion 630 of the guiding portion 73 is better in the present invention, and the figure is shown in FIG. 3 . The bidirectional rotating sleeve 30 is used by the user to rotate the supporting seat portion 50 and the protruding column portion 41 And the tapered coercible pressing block 70 is destructively caused to cause the screw to rotate upward when the rotating sleeve 30 is in the upward direction of the threaded section 41, and the outer side of the double inner lower tapered edge is formed to be close to the main The angled abutment between the tapered edge portion of the tapered portion 60 of the threaded portion 41 of the tapered portion 60 of the threaded portion 70 is also increased by the renal pelvis, which in turn promotes the upper portion. The elastic claw portion 63 is stretched outwardly and is in close contact with the inner wall of the main rod 1〇; thereby achieving the two-way pressing effect expected by the present creation.
