[0020] Hereinafter, embodiments of the anchor structure for drilling of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-3The present invention shows an embodiment of an anchor structure for drilling, comprising a hollow anchor tube 1: a spiral sheet 2 is welded on the bottom of the surface of the hollow anchor tube 1, a plurality of arc-shaped sockets 6 are provided on the front side of the hollow anchor tube 1, a circular socket 7 is provided on the top of the front side of the hollow anchor tube 1, and the coordinated use of the arc-shaped sockets 6 and the circular sockets 7 facilitates the user to rotate the hollow anchor tube 1 with a wrench and a crowbar, so that the spiral sheet 2 can be rotated and drilled into the ground, a base 3 is welded on the top of the hollow anchor tube 1, a clamping assembly 4 is arranged on the top of the base 3, the clamping assembly 4 comprises a U-shaped bolt 41, arc-shaped sockets 42 are provided on both sides of the top of the base 3, the bottom end of the U-shaped bolt 41 passes through the arc-shaped socket 42 and extends to the bottom of the base 3, the surfaces of both ends of the U-shaped bolt 41 are threadedly connected with two first nuts 43, the top of the base 3 Two limiting protrusions 44 are welded on the front and rear sides of the part, and the top of the limiting protrusion 44 is set to an arc surface. A traction assembly 5 is set on the top of the base 3, and the traction assembly 5 includes a fixing tube 51 welded on both sides of the top of the base 3, and a threaded pin 52 is inserted in the inner cavity of the fixing tube 51. Two second nuts 53 are threadedly connected to the surface of the threaded pin 52 on one side, and a pull rod 54 is rotatably connected to the surface of the threaded pin 52. An arc-shaped groove 55 adapted to the pull rod 54 is provided on the front side of the top of the base 3. Through the setting of the traction assembly 5, the fixing tube 51, the threaded pin 52 and the second nut 53 are used in coordination, which plays a role in connecting and fixing the base 3 and the pull rod 54. The arc-shaped groove 55 is opened, so that the pull rod 54 can be hidden when not in use, thereby avoiding obstruction to the U-bolt 41 when clamping the pipe fitting.

[0022] Working principle: When the utility model is used, the user places the bottom end of the hollow anchor tube 1 at the anchor point position, then inserts a wrench into the inner cavity of the arc-shaped socket 2 6, or uses a long crowbar to insert into the inner cavity of the circular socket 7, and rotates the hollow anchor tube 1. The hollow anchor tube 1 drives the spiral piece 2 to rotate during the rotation, and the shape of the spiral piece 2 causes the hollow anchor tube 1 to rotate and be inserted into the ground. After the hollow anchor tube 1 is completely inserted into the ground, the user places the chassis pipe fitting to be fixed on the top of the base 3, and then inserts the U-bolt 41 vertically downward from the top of the base 3, so that the U-bolt 41 passes through the inner cavity of the arc-shaped socket 1 42, and the first nut 43 is threadedly connected to the bottom of the U-bolt 41, so that the U-bolt 41 clamps and fixes the pipe fitting to be fixed. When it is necessary to use a rope to pull and fix the drilling equipment, the user rotates the pull rod 54 to disengage the pull rod 54 from the inner cavity of the arc-shaped groove 55, and fixes the end of the rope away from the equipment on the surface of the pull rod 54.

[0023] In summary, the drilling anchor structure installs and fixes the base 3 through the coordinated use of the hollow anchor pipe 1 and the spiral sheet 2, and then clamps and fixes the pipe through the setting of the clamping component 4. The setting of the traction component 5 makes it convenient for the user to fix the rope to the base 3, thereby achieving the purpose of convenient installation and fixation and simultaneous clamping and traction fixation.
