[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:
[0022] According to the instruction manual Figure 1-4It can be known that the cone head 1, the shell 12, the fixing rod 14, the threaded rod 13 and the auxiliary wrench 7 in the utility model are made of high-strength alloy steel material, and the shell 12 is a part of the ground pile structure. When in use, the auxiliary wrench 7 is pulled out, the shell 12 is vertical, the tip is facing downward, and the person uses a hammer or other tool to insert the shell 12 and the cone head 1 into the ground. The insertion depth scale can be set on the side surface of the shell 12, and a certain depth is inserted. It should be noted here that it is not necessary to insert too deep, which is convenient for subsequent extraction. According to the experience of the personnel, the insertion is deeper when the soil is loose, and shallower when the soil is compact. It is common knowledge for those skilled in the art. After the shell 12 is inserted, the auxiliary wrench 7 is inserted into the socket 9 so that the hexagonal prism groove 6 is buckled on the hexagonal prism body 10. The personnel use a crowbar or an iron rod to insert it into the through hole 8. Through the principle of leverage, the personnel can conveniently turn the auxiliary wrench 7 to drive the hexagonal prism body 10 and the threaded rod 13 to rotate. Since the movable block 15 is screwed to the threaded rod 13 through the threaded hole 3, the fixed rod 14 is connected to the side wall of the movable block 15 in the vertical direction, and the fixed rod 14 is inserted into the guide hole 4. Therefore, the movable block 15 can move up and down on the threaded rod 13, thereby pushing the fixed rod 14 to move. Under the limiting action of the guide hole 4, the fixed rod 14 extends out of the guide hole 4 and is inserted into the soil, thereby increasing the stability of the shell 12 in the soil. The design of the fixed rod 14 solves the problem of poor stability caused by the shell 12 being inserted too shallowly, and it is convenient to pull out the shell 12 during disassembly.
[0023] A limit plate 5 is disposed at the upper part of the cavity of the shell 12, and a limit hole 11 matching the diameter of the threaded rod 13 is opened at the center of the limit plate 5. The threaded rod 13 passes through the limit hole 11 to ensure the stability of the threaded rod 13 during rotation.
[0024] Among them, a through auxiliary hole 17 is opened on the side surface of the shell 12 near the upper end surface, and the auxiliary wrench 7 can be inserted into the auxiliary hole 17. When pulling out the shell 12, the auxiliary wrench 7 is inserted into the auxiliary hole 17, and the person rotates and twists it back and forth to facilitate pulling out the shell 12.
[0025] The front end of the fixing rod 14 is designed to be an arc surface 16 and a pointed tip, so as to ensure that the fixing rod 14 can stably extend out of the limiting hole 11 and can penetrate the soil more easily.
[0026] The fixed rod 14 is rotatably connected to the side wall of the moving block 15 via the rotating shaft 2. The rotating shaft 2 is a prior art, which only needs to ensure that the fixed rod 14 rotates in the vertical direction to ensure stability in other directions.
[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
