[0039] Further, such as Figure 1 and Figure 2 As shown, a limiting groove 106 is provided on the limiting plate 105 , and a limiting wheel 107 is slidably connected in the limiting groove 106 . The limiting wheel 107 is connected to the side of the moving seat 103 . The limiting wheel 107 and the limiting groove 106 also play a role in limiting the moving seat 103 .
[0040] Example 2 further optimizes the directional drilling calibration device provided in Example 1. Specifically, Figure 1-Figure 4 As shown, two support frames 2 are interspersed and connected on the support seat 1, and a second calibration guide wheel 201 is connected between the two support frames 2. The second calibration guide wheel 201 is located above the two first calibration guide wheels 104. The second calibration guide wheel 201 can further limit the directional drilling to reduce the drill bit jumping or offset.
[0041] Further, such as Figure 1 As shown, a cylinder 202 is fixedly installed between the side of the support frame 2 and the support seat 1. The cylinder 202 is used to drive the support frame 2 to rise and fall. The cylinder 202 can drive the second calibration guide wheel 201 to rise and fall through the support frame 2, thereby adjusting the position of the second calibration guide wheel 201.
[0042] Example 3, further optimizes the directional drilling calibration device provided in Example 1 or 2, specifically, as follows Figure 1-Figure 4 As shown, an angle adjustment portion is provided at the bottom of the support seat 1, and the angle adjustment portion is used to adjust the angle of the support seat 1 to adapt to the angle of the drill bit.
[0043] Further, such as Figure 1-Figure 4 As shown, the angle adjustment part includes a connecting plate 3 fixedly installed on the bottom of the support seat 1, and the first connecting seats 301 are fixedly connected on both sides of the bottom of the connecting plate 3, and a transmission shaft 302 is fixedly connected between the two first connecting seats 301.

Adjust the angle of the support seat 1 according to the actual situation, rotate the first bidirectional screw 102 to make the two movable seats 103 move, and adjust the distance between the two movable seats 103 according to the actual situation. The drill bit passes through the first calibration guide wheel 104 and the second calibration guide wheel 201, so that the drill bit contacts the two first calibration guide wheels 104, and then the cylinder 202 drives the support frame 2 to descend so that the second calibration guide wheel 201 presses the drill bit. At this time, the second calibration guide wheel 201 and the first calibration guide wheel 104 cooperate with each other to achieve the calibration limit of the drill bit.
