[0024] The top semi-automatic adjustment head 4 is an important mechanism for realizing the combination and separation of the adjustment rod and the medicine tube, and for pushing and adjusting the medicine tube. Figure 2As shown, the top semi-automatic adjustment head 4 includes an alignment pin 10, an outer cylinder 11, a pin telescopic assembly, an upper outer plate 13 and a lower outer plate 14; the alignment pin 10 is a cross-shaped pin, and the two ends of the outer cylinder 11 are respectively connected to the upper outer plate 13 and the lower outer plate 14; the alignment pin 10 slides through the middle of the upper outer plate 13 and is connected to the pin telescopic assembly; the lower outer plate 14 is fixedly connected to the main rod body 1; one end of the transmission shaft 6 slides through the middle of the lower outer plate 14 and is connected to the pin telescopic assembly; since the transmission shaft 6 is relatively long, in order to improve the installation accuracy, the transmission shaft 6 is prevented from rotating When jitter and deviation occur, the utility model limits and fixes the transmission shaft 6 and the alignment latch 10 through a latch telescopic assembly, and the latch telescopic assembly includes two coaxially arranged roller bearings 18, and an annular slide 19 is installed between the two roller bearings 18; bearing fixing plates 20 are respectively provided at both ends of the roller bearing 18; the two bearing fixing plates 20 are clamped and connected by a U-shaped side fixing plate 21; the transmission shaft 6 is inserted through the roller bearing 18, the annular slide 19 and the middle part of the bearing fixing plate 20 and is connected to the alignment latch 10, and the transmission shaft 6 and the annular slide 19 are fixedly connected.

The method of using the semi-automatic adjustment rod is as follows: when in use, the operating handle 5 is first pushed upward to extend the cross-shaped alignment pin 10, and the operating handle 5 is twisted to the left after the limiting round pin 7 reaches the end of the limiting round pin 7 slide groove, and the operating handle 5 is pulled downward to make the limiting tube 8 lock the limiting round pin 7 after the limiting round pin 7 reaches the limiting round pin 7 slide groove 16. The device enters a ready-to-fire state; the cross-shaped alignment pin 10 is aligned with the cross-shaped interface at the lower part of the medicine tube (not shown in the figure) and is inserted and fixed with force to complete the connection; after the medicine tube is pushed into the blast hole through the medicine pushing rod for adjustment, the operating handle 9 is pushed upward to release the locking state of the limiting round pin 7, and the operating handle 5 is twisted to the right to make the limiting round pin 7 enter the limiting round pin 7 slide groove, and the operating handle 5 is pulled downward to make the cross-shaped alignment pin 10 detach from the medicine tube under the transmission of the transmission shaft 6 to complete a loading task.
