When the drill bit 5 is installed and fixed, the connecting rod 71 is inserted into the box body 731. When the connecting rod 71 is inserted into the box body 731, the box body 731 squeezes the clamping head 724, so that the clamping head 724 moves into the moving groove 721. At the same time, the two moving rods 723 move in the retraction groove 722 and compress the push spring 725. After the connecting rod 71 is completely inserted into the box body 731, the clamping head 724 will correspond to the clamping groove 732, and the push spring 725 will be pressed. 5 will rebound and push the clamping head 724 into the clamping groove 732, so that it is clamped in the clamping groove 732, thereby completing the installation and fixation of the drill bit 5. When it is disassembled, by pulling the moving ring 7333 downward, the moving ring 7333 moves on the surface of the box body 731, stretching the tension spring 7332, and at the same time driving the four extrusion blocks 7334 to move downward in the clamping groove 732. When the extrusion blocks 7334 move downward, the clamping head 724 is squeezed and moved into the moving groove 721. At the same time, the push spring 725 is compressed, and the moving rod 723 moves in the retraction groove 722, thereby releasing the clamping fixation and removing the drill bit 5.

[0035] In summary, the pile foundation coring detection device with installation and positioning function solves the problem that the existing pile foundation core pulling machine cannot position the drill bit, resulting in the drill bit swinging when rotating, and the drill bit of the existing pile foundation core pulling machine is usually installed and fixed by threaded bolts, which is more troublesome during installation and disassembly, resulting in unstable rotation of the drill bit and inconvenience in disassembling the drill bit.
