[0025] It comprises an ore crushing mechanism 1, and the ore crushing mechanism 1 is provided with an ore crushing grabbing mechanism 2 on the front end outer ring.

[0026] The ore crushing mechanism 1 comprises a shell 11, a hollow pipe 110 fixed through the front end surface of the shell 11, and a rotating shaft 14 vertically arranged in the inner cavity of the shell 11, wherein the outer ring of the rotating shaft 14 in the inner cavity of the shell 11 is fixed with a driving gear 15, the front side of the top surface of the inner cavity of the shell 11 is rotationally connected with a driven gear 18 engaged with the driving gear 15, and the bottom end of the driven gear 18 is fixedly connected with a first bevel gear 12; the left and right side ports of the shell 11 are both fixedly connected with an end cover 13 through screws.

[0027] The front end of the shell 11 penetrates a transmission shaft 111, the rear end of the transmission shaft 111 is fixedly connected with a second bevel gear 19 engaged with the first bevel gear 12, the inner cavity of the hollow pipe 110 is movably provided with an impact drill bit 112, the rear end of the impact drill bit 112 is in contact with the front end of the transmission shaft 111, and the end surfaces of the transmission shaft 111 and the impact drill bit 112 in contact with each other are both provided with inclined surfaces.

[0028] The ore crushing and grabbing mechanism 2 comprises a fixed pipe 21 fixed on the front side of the outer ring of the hollow pipe 110, a movable sleeve pipe 23 movably sleeved on the outer ring of the hollow pipe 110, and 10-14 C-shaped elastic sheets 22 fixed in an annular array on the outer ring surface of the fixed pipe 21, wherein the outer ring surface of the movable sleeve pipe 23 is hingedly connected with 10-14 metal strips 24 in an annular array, and the ends of the C-shaped elastic sheets 22 away from the fixed pipe 21 are fixedly connected with the inner side surfaces of the metal strips 24, respectively.

[0029] The bottom end of the rotating shaft 14 is rotationally connected with the bottom surface of the inner cavity of the shell 11, the top end of the rotating shaft 14 penetrates to the upper side of the shell 11, and the top end of the rotating shaft 14 fixedly connected with a crank 17 above the shell 11; the bottom end of the first bevel gear 12 is rotationally connected with the bottom surface of the inner cavity of the shell 11, the inner cavity of the hollow pipe 110 is provided with a sliding bearing matched with the transmission shaft 111, and the rear end surface of the shell 11 is fixedly connected with a handle 16.
