[0026] Furthermore, the adjustment component includes a slot 14, an insertion rod 15, a fixed plate 16, a spring 17 and a sleeve 18. A fixed plate 16 is provided at one end of the bottom of the adjustment plate 5, and a sleeve 18 is provided at the bottom of one end of the fixed plate 16. The insertion rod 15 is slidably inserted into the inner side of the sleeve 18. A plurality of slots 14 matching with the insertion rod 15 are provided at one end of the movable plate 2, and a spring 17 is sleeved on the outer side of the insertion rod 15. When the adjustment plate 5 is aligned with the blast hole, the insertion rod 15 can be pulled out of the slot 14, and the sliding adjustment plate 5 can be moved to the specified position and inserted into the corresponding slot 14 to complete the position adjustment of the adjustment plate 5.

[0027] Furthermore, a scale is provided on one side of the top of the adjustment plate 5 , and a pointer is provided on the top of one end of the positioning block 13 , and the position of the positioning block 13 can be adjusted by observing the scale pointed by the pointer.
