Detailed ways

In order to make it easier to understand the structure of the present utility model and the functional features and advantages that can be achieved, the preferred embodiments of the present utility model will be described in detail below in conjunction with the drawings:

Example 1:

As shown in FIGS. 1 to 5 , the present invention provides a measuring drill with a scale, including a drill body 1 and a plunger 2 each provided with a scale line 3, wherein the drill body 1 is a tubular structure, and the plunger 2 One end is the tip 21, so that the probe can be easily inserted into the soil through the tip 21; the other end of the insertion rod 2 is detachably connected with the end of the drill body 1, so that the probe can be divided into two parts by detachable connection. The end of the insertion rod 2 is hinged with a rotating rod 4, the end of the rotating rod 4 is hinged with a limit rod 5, and the end of the limit rod 5 is connected with a limit member 6, so that the insertion rod 2 can pass the limit The positioning member 6 can be rotatably arranged at one end of the drill body 1, so that when the insertion rod 2 is rotatably connected with the drill body 1, the limiting member 6 can rotate together with the insertion rod 2 in the drill body 1; For the lock ring 7 for locking the folded tip 21, it is convenient to limit the tip 21 of the folded insertion rod 2, avoid the problem of the tip 21 being exposed, and effectively prevent the tip 21 from being stabbed in work. Personnel problems arise.

The inner end of the drill body 1 is fixedly provided with an internal thread sleeve 8, the end of the insertion rod 2 is provided with an external thread 22, and the insertion rod 2 is threadedly connected with the internal thread sleeve 8 through the external thread 22, so that the insertion rod 2 and the drill body 1 are threaded. The connection is detachable, so that the outer thread 22 at the end of the insertion rod 2 can be folded and stored after being separated from the inner thread sleeve 8 in the drill body 1 . The limiting member 6 is a cylindrical block or a sphere, and the limiting member 6 is connected with the limiting rod 5 by screw thread. The diameter of the limit member 6 is larger than the inner diameter of the female threaded sleeve 8 to limit the end of the limit rod 5, so that when the end of the limit rod 5 moves to the end of the female threaded sleeve 8, the limit member 6 can pass through. Limit the position, so that the insertion rod 2 is completely separated from the end of the drill body 1 . One end of the drill body 1 is provided with a U-shaped groove 11 for limiting the position of the rotating rod 4 , so that the rotating rod 4 can be rotated by 90 degrees to limit the position by setting the U-shaped groove 11 . The insert rod 2 is covered with a washer 10 at the 22 section of the external thread, and the washer 10 is protruded with a U-shaped piece 101 that is inserted into the U-shaped groove 11, so as to pass through the rotatable sleeve of the external thread 22 section on the insert rod 2. The gasket 10 and the U-shaped piece 101 on it seal the U-shaped groove 11 to prevent the soil from entering the drill body 1 through the U-shaped groove 11 when the insertion rod 2 is inserted into the soil deeper than the U-shaped groove 11 .
