[0049] A second extruding head 3 threadedly connected to the mounting rod 1, that is, the second extruding head 3 is threadedly connected to the threaded portion;

[0050] The end of the first extruding head 2 and / or the end of the second extruding head 3 is provided with a beveled sliding surface;

[0051] An adjustment gap 8 is left between the inside of the first extruding head 2 and / or the inside of the second extruding head 3 and the outer side wall of the mounting rod 1;

[0052] When the lower end of the mounting rod 1 is inserted into the anchor hole 9 under the ground, the first extruding head 2 and the second extruding head 3 are both placed in the anchor hole 9, and the second extruding head 3 abuts against the inner wall of the anchor hole 9 and there is a friction force therebetween;

[0053] When the mounting rod 1 is rotated, the second extruding head 3 rotates relative to the mounting rod 1, and the second extruding head 3 is stationary (does not rotate) relative to the anchor hole 9. Since the position of the mounting rod 1 in the anchor hole 9 does not change (only rotates), the second extruding head 3 moves on the mounting rod 1 through the threaded portion, so that the first extruding head 2 and the second extruding head 3 approach each other, and under the guidance of the beveled sliding surface, the ends of the first extruding head 2 and the second extruding head 3 are staggered (for example, Figure 4 The lower end of the first extruding head 2 is inclined to the right, and the upper end of the second extruding head 3 is inclined to the left) and abuts against the inner wall of the anchor hole 9, so as to realize that the mounting rod 1 is fixed in the anchor hole 9; without being fixed by concrete, the installation is simple and convenient, has high adaptability, and is flexible and convenient to use.

[0054] The end of the first extruding head 2 and / or the end of the second extruding head 3 is provided with a bevelled sliding surface, that is, the end of the first extruding head 2 close to the second extruding head 3 is provided with a bevelled sliding surface, and the end of the second extruding head 3 is not provided with a bevelled sliding surface; or the end of the first extruding head 2 is not provided with a bevelled sliding surface, and the end of the second extruding head 3 close to the first extruding head 2 is provided with a bevelled sliding surface; or the end of the first extruding head 2 and the end of the second extruding head 3 close to each other are both provided with a bevelled sliding surface;

[0055] In the design scheme, the first extruding head 2 and the second extruding head 3 are both provided with a bevelled sliding surface, specifically, the lower end of the first extruding head 2 has an inclined surface one 21 (bevelled sliding surface), and the upper end of the second extruding head 3 has an inclined surface two 31 (bevelled sliding surface);

[0056] When the first extruding head 2 is located above the second extruding head 3 and the first extruding head 2 and the second extruding head 3 close to each other, the inclined surface one 21 and the inclined surface two 31 abut and move, and the inclined surface one 21 slides on the surface of the inclined surface two 31, so that the lower end of the first extruding head 2 and the upper end of the second extruding head 3 move in opposite directions respectively, thereby realizing that the outer side walls of the first extruding head 2 and the second extruding head 3 abut and fix with the inner wall of the anchor hole 9.

[0057] The inside of the first extruding head 2 and / or the inside of the second extruding head 3 and the outer side wall of the mounting rod 1 leave an adjusting gap 8; that is, at least one of the first extruding head 2 and the second extruding head 3 and the outer side wall of the mounting rod 1 leave an adjusting gap 8, and in the design scheme, the first extruding head 2 and the second extruding head 3 both leave an adjusting gap 8 with the outer side wall of the mounting rod 1, and the adjusting gap 8 is used to realize that the first extruding head 2 and / or the second extruding head 3 incline on the mounting rod 1, thereby realizing that the ends of the first extruding head 2 and the second extruding head 3 close to each other are dislocated.

[0058] The threaded part has a threaded segment one 12 and a threaded segment two 13, and the threaded directions of the threaded segment one 12 and the threaded segment two 13 are opposite, and the threaded segment one 12 and the threaded segment two 13 are sequentially located on the side wall of the mounting rod 1, or the threaded segment one 12 and the threaded segment two 13 are staggered distributed on the mounting rod 1 to make the mounting rod 1 a double-threaded screw rod, the first extruding head 2 is threadedly connected with the threaded segment one 12, and the second extruding head 3 is threadedly connected with the threaded segment two 13; when the mounting rod 1 rotates, because the outer side walls of the first extruding head 2 and the second extruding head 3 abut with the inner wall of the anchor hole 9, under the action of the threaded part, the first extruding head 2 and the second extruding head 3 move on the mounting rod 1 and close to each other, and the first extruding head 2 and the second extruding head 3 do not rotate in the anchor hole 9, but only move up and down in the anchor hole 9.

[0059] The mounting rod 1 is threadedly connected with a nut one 5, the nut one 5 and the threaded segment one 12 are threadedly connected, the nut one 5 movably connects the end of the first extruding head 2, and is used to limit the movement of the first extruding head 2 on the mounting rod 1; the nut one 5 is fixedly connected with the first extruding head 2 or the nut one 5 movably abuts against the first extruding head 2.

[0060] When the first nut 5 is fixedly connected with the first extruding head 2, when the installation rod 1 is rotated, the first nut 5 will move on the installation rod 1, thereby driving the first extruding head 2 to move downward and abut against the upper end of the second extruding head 3.

[0061] When the first nut 5 is movably connected with the first extruding head 2, the first extruding head 2 is sleeved on the installation rod 1 and can rotate on the installation rod 1, and the first nut 5 is used to limit the first extruding head 2 to move upward and downward on the installation rod 1.

[0062] The second nut 6 is threadedly connected on the installation rod 1, the second nut 6 is threadedly connected with the threaded segment 13, the second nut 6 movably connects the end of the second extruding head 3, and the second extruding head 3 is threadedly connected on the installation rod 1; the connecting mechanism between the second nut 6 and the second extruding head 3 is that the pins are sequentially inserted from the lower end of the second nut 6 to the lower end of the second extruding head 3, or the connecting mechanism is that the second nut 6 and the second extruding head 3 are connected through the embedded block and the embedded groove, or the connecting mechanism is that the second nut 6 and the second extruding head 3 are connected through gluing.

[0063] The lower end of the second extruding head 3 is provided with a limiting groove 32, and the second nut 6 is clamped in the limiting groove 32; the second nut 6 is a square nut, and the second nut 6 and the limiting groove 32 are connected through embedding.

[0064] The outer side wall of the first extruding head 2 is provided with a plurality of anti-disengagement protrusions 22, the anti-disengagement protrusions 22 are inclinedly arranged towards the upper end of the first extruding head 2, when the first extruding head 2 is clamped in the anchor hole 9, the anti-disengagement protrusions 22 abut against the anchor hole 9, thereby increasing the friction between the first extruding head 2 and the inner wall of the anchor hole 9, ensuring the stable installation of the first extruding head 2 in the anchor hole 9, and ensuring the stable and firm installation of the anchor rod.

[0065] The upper end of the installation rod 1 is a square portion 11, which facilitates the rotation and twisting of the installation rod 1.

[0066] The lower end side of the inclined surface one 21 is transitioned through the arc surface one 23, and the upper end side of the inclined surface two 31 is transitioned through the arc surface two 33.

[0067] The outer side wall of the second extruding head 3 is a smooth surface; in use, the first extruding head 2 abuts against the inner wall of the anchor hole 9, when the installation rod 1 is rotated, the second extruding head 3 will rotate together with the installation rod 1, when the inclined surface two 31 of the second extruding head 3 abuts against the inclined surface one 21 of the first extruding head 2, since the first extruding head 2 is limited to rotate by the anchor hole 9, at this time, the first extruding head 2 makes the second extruding head 3 no longer rotate together with the installation rod 1, thereby making the second extruding head 3 move on the installation rod 1 towards the first extruding head 2, thereby realizing the guiding effect of the beveling sliding surface, so that the first extruding head 2 and the second extruding head 3 are staggered at the ends.
