[0054] In this utility model, a guide frame 20 is fixed at the lower end of the front part of the mounting bracket 6, and both sides of the guide frame 20 are slidably connected to the guide block 18 and the drag block 19.

[0055] In use, the mounting bracket 6 limits the empty slots on both sides of the drag block 19 through the guide frame 20 and guide block 18, which helps the drag block 19 to rise and fall stably.

[0056] In this embodiment, during use: First, driven by the motor 5, the driving wheel 4 rotates, causing the driven wheel 3 to rotate. The two driven wheels 3 rotate synchronously, causing the two drill rods 1 to rotate. In conjunction with the extension of the electric push rod 8, the protective chamber 2 moves downward, further causing the drill rods 1 to move downward, allowing them to drill into the medium supporting the bottom of the device. This facilitates device positioning. Furthermore, the bracket 14, through the sliding seat 13, limits the sliding rod 10, ensuring stable lifting and lowering of the drill rods 1. Then, the drag block 19 can be pulled downward, causing the wire groove 17 to move downward and the spring 21 to compress, making room for the wire and allowing the wire to be threaded through. The wire is placed between the pressure roller 16 and the wire groove 17 at the rear end of the pressure roller 16, which helps to keep the wire stable during the unwinding process. In addition, the mounting frame 6 limits the empty grooves on both sides of the drag block 19 through the guide frame 20 and the guide block 18, which helps to stabilize the lifting and lowering of the drag block 19. Then, the handle 12 can be rotated to rotate the wire 15 through the screw block 11 to rewind the wire. After the rewinding is completed, the guide slider 22 can be rotated to one side of the mounting frame 6 so that the limiting ring 23 fits with the screw block 11 to prevent the wire on the wire 15 from becoming loose. In summary, the device has good stability and good wire unwinding effect during the unwinding process.
