[0029] The usage method and advantages of the present utility model: When this kind of mortar anchor rod hole former is working, the working process is as follows:

[0030] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the device is connected to an external driving device through the anchor handle 101. When the driving device starts, it drives the anchor handle 101 and the anchor rod body 102 to rotate. Then, through the docking block 201 and the connecting block 301, it drives the main drill bit 401 and the cutting teeth 402 to rotate. The main drill bit 401 and its cutting teeth 402 start to cut the rock and soil to form a hole. During the drilling process, the driving device can be temporarily stopped to inject coolant from the first material passage cavity 103. The coolant flows out from the second material passage hole 403 through the second material passage cavity 302, reducing the temperature of the drill bit, reducing wear, and improving the drilling quality. After drilling, mortar can be injected through the first material passage cavity 103. The mortar flows out through the first material passage hole 104 and the second material passage hole 403 to reinforce the anchor rod body 102. After drilling, the anchoring work on the soil can be quickly completed, improving the work efficiency. When the drill bit needs to be installed on the anchor rod body 102, the first locking block 502 and the second locking block 505 are in a telescopic state under the elastic force of the first spring 501 and the second spring 504.

The first spring 501 is compressed. At the same time, when the second locking block 505 contacts the working groove 304, it is retracted into the groove 503 through the inclined surface. When the docking block 201 is initially fixed in the second material passage cavity 302 by rotating through the thread, the first locking groove 202 is flush with the working groove 304. The first locking block 502 enters the first locking groove 202 under the elastic force of the first spring 501. At the same time, the second locking block 505 enters the second locking groove 203 under the elastic force of the second spring 504. By simply rotating the anchor rod body 102, it can be docked and fixed with the first drill bit part 3, improving the installation efficiency. At the same time, the double locking mechanism improves the stability and reliability of the connection, ensuring the stability during the drilling process.
