Fig. 4 is a schematic use view of the limiting tool, and with reference to fig. 4, when a bottom hole is machined by the limiting tool provided in the embodiment of the present invention, first, the upper semicircular seat 11 and the lower semicircular seat 12 are fitted onto an oil pipe, so that the oil pipe 100 is clamped into the clamping space a, then, according to the designed hole depth of the bottom hole, the distance between the limiting plate 2 and the upper semicircular seat 11 is adjusted, and after the adjustment is completed, the slider 3 is locked and fixed in the sliding groove 112 by the locking screw 113, thereby completing the whole installation process of the limiting tool. The drill is inserted into the second pilot hole 21 and the first pilot hole 111 in sequence and abuts against the outer wall of the oil pipe 100. And starting the drill bit, wherein the drilling head of the drill bit is abutted against the opening of the second guide hole 21 at last along with the drill bit which drills into the oil pipe 100, and the hole depth of the bottom hole is the designed hole depth. That is to say, the limiting tool provided by the embodiment of the invention can effectively control the hole depth of the processed bottom hole, and is simple to operate.
Optionally, gaskets are arranged on the inner walls of the upper semicircular seat 11 and the lower semicircular seat 12, so that damage to the oil pipe 100 caused by the upper semicircular seat 11 and the lower semicircular seat 12 in the process of clamping the oil pipe 100 is avoided.
In this embodiment, the two sides of the lower semicircular seat 12 are provided with mounting bosses 121, each mounting boss 121 is provided with an insertion hole for inserting a fixing bolt 122, and the upper semicircular seat 11 is provided with a screw hole matched with the fixing bolt 122.
