The locking grooves designed in the electronic compartment increase the overall length of the instrument, increase the rigidity of the guide head, and reduce the instrument's ability to create inclinations.

[0048] In view of this, the present invention provides a primary electronic bin disassembly device for rotational orientation, comprising: a pull-out body 1, a stopper 2, an ejection assembly 3 and a locking claw 4; the pull-out body 1 passes through the inner cavity of the ejection assembly 3 and extends into the drive shaft 10; the stopper 2 is sleeved on the end of the pull-out body 1 away from the drive shaft 10, and is threadedly connected to the pull-out body 1; the locking claw 4 is sleeved on the end of the pull-out body 1 extending into the drive shaft 10, the bottom of the locking claw 4 is trumpet-shaped, and the locking claw 4 is used to clamp with the upper electronic bin 9; the ejection assembly 3 is provided with an ejection rod 31, the pull-out body 1 is inserted into the ejection rod 31, and the ejection rod 31 is extended, the ejection rod 31 can push the stopper 2 to move in the direction away from the drive shaft 10, so as to drive the pull-out body 1 to pull out the upper electronic bin 9.

[0049] The locking claw 4 is mounted on one end of the pull-out body 1 extending into the drive shaft 10, and the stopper 2 is installed on the pull-out body 1 through a thread. The bottom of the locking claw 4 is in a trumpet shape, and the trumpet is used to lock the inner edge of the electronic bin. The ejector rod 31 supports the stopper 2 and drives the stopper 2 to move to eject the pull-out body 1, so that the pull-out body 1 is pulled out of the electronic bin through the locking claw 4. The device can easily and quickly pull out the electronic bin 9 on the guide head without the need to use the guide head drill collar buckle for fixing.

The bottom of the locking claw 4 is in the shape of a trumpet, and the trumpet is used to lock the inner edge of the electronic compartment. The trumpet is pinched to shrink the trumpet, which is convenient for the tooling to detach from the electronic compartment. The trumpet bevel of the locking claw 4 forms an angle of a certain degree with the horizontal line.

[0063] The upper edge of the power-assisted lock nut 6 is provided with a first outer chamfer 61, which is the same as the inner chamfer 41 at the bottom of the locking claw 4, and can assist in disassembling the electronic compartment. The power-assisted lock nut 6 is provided with two torque wrench clamping edges for easy clamping of the torque wrench.
