The connecting spring 63 is fixedly connected to the mounting slot 5 at one end away from the moving block 61, and the moving block 61 is fixedly connected to the mounting slot 5 through the connecting spring 63. A connecting rod 64 is fixedly connected to the surface of the moving block 61 away from the connecting spring 63. By inserting a flat screwdriver into the toggle slot 62, the combination of the moving block 61 and the connecting rod 64 can be moved, and at this time, the connecting spring 63 is deformed to generate elastic force;

[0024] A limiting block 7 is clamped and slidably connected to the outer surface of the charge tube 1. A clamping block 8 is fixedly connected to the inner surface of the limiting block 7. A clamping groove 12 is formed in the outer surface of the charge tube 1. The inner surface of the clamping groove 12 is in fitting and sliding connection with the clamping block 8. The clamping block 8 moves in the clamping groove 12 to prevent the limiting block 7 from rotating on the outer surface of the charge tube 1. A limiting mechanism 9 is provided on one surface of the limiting block 7. The limiting mechanism 9 includes a limiting box 91 fixedly connected to one surface of the limiting block 7. A lifting plate 92 is clamped and slidably connected to the inner cavity of the limiting box 91. A limiting spring 93 is fixedly connected to the top surface of the lifting plate 92.

[0025] Connection holes matching the structural dimensions of the connecting rod 64 are formed in the front and rear side surfaces of the inner cavity of the placement groove 3. The inner surface of the placement groove 3 is in sealing and fitting sliding connection with the pick-and-place plate 4. The outer surface of the pick-and-place plate 4 is flush with the outer surface of the charge tube 1, which will not affect the sliding of the pick-and-place plate 4. The outer surface of the pick-and-place plate 4 is in fitting and sliding connection with the inner surface of the limiting block 7. Slots matching the structural dimensions of the connecting rod 64 are formed at both the front and rear ends of the pick-and-place plate 4. One end of the connecting rod 64 away from the moving block 61 penetrates and is movably connected to the pick-and-place plate 4 and is inserted into the connection hole in the inner cavity of the placement groove 3 to install the position of the pick-and-place plate 4 in the placement groove 3.

[0026] It should be noted that: the bottom surface of the limiting box 91 is in fitting and sliding connection with the pick-and-place plate 4. One end of the limiting spring 93 away from the limiting column 94 is fixedly connected to the limiting box 91. Both the upper and lower ends of the limiting column 94 penetrate and are movably connected to the limiting box 91. By pulling the part of the limiting column 94 exposed above the limiting box 91, the overall movement of the lifting plate 92 and the limiting column 94 can be driven. At this time, the limiting spring 93 will deform and generate elastic force.

[0027] Working principle: When in use, pull the limit column 94 part leaking from the upper part of the limit box 91 to move the limit column 94 away from the limit hole 13. At this time, the limit block 7 can be slid on the outer surface of the charge tube 1. At this time, the embedded block 8 slides in the inner cavity of the card slot 12 to prevent the limit block 7 from rotating. The limit block 7 is adjusted to multiple positions to change the length of the charge tube 1 inserted into the blasting hole. Further, after the limit block 7 is adjusted, the explosive is inserted into the inner cavity of the charge tube 1. The wire placement port opened on the pressure plate 11 avoids squeezing the explosive wire. Further, through the cylinder 2 extends to drive the movement of the moving plate 10 and the pressure plate 11 assembly, pushing the explosive into the blasting hole to complete the charging operation. Furthermore, if the limiting hole 13 on the pick-up and placement plate 4 is blocked by dust or small particles and debris, the limiting block 7 assembly is removed at this time, and a flat-blade screwdriver is inserted into the toggle slot 62 on the moving block 61 to toggle the moving block 61, so that the connecting spring 63 is deformed, and the connecting rod 64 leaves the connecting hole opened in the inner cavity of the placement slot 3. The pick-up and placement plate 4 is removed, and the placement slot 3 and the limiting hole 13 are conveniently cleaned, which is more labor-saving.
