Example 1:

the drill bit shackle provided by the embodiment, as shown in fig. 1 to 3, includes a housing 1, the housing 1 is a tubular structure with one end closed and the other end open, and an accommodating cavity 11 is provided inside the housing 1, an introducing port 2 is provided on a side wall of the housing 1, the introducing port 2 extends from the closed end of the housing 1 to an open end of the housing, a clamping portion 5 for clamping a drill bit is provided at the open end of the housing 1, a limiting member 3 is provided at a position corresponding to the introducing port 2, and two ends of the limiting member 3 are detachably connected to the clamping portion 5 and can enable the open end of the introducing port 2 to be in an open state or a closed state. The introduction port 2 communicates with the accommodation chamber 11. When the drill bit is installed in the drill bit shackle of the present embodiment, the limiting member 3 is first removed or rotated to one side of the introduction port 2, so that the introduction port 2 is in an open state, the drill bit 6 is installed in the accommodating cavity 11 of the housing 1 along the introduction port 2, the jaw portion 61 of the drill bit 6 is clamped in the clamping portion 5, and then the limiting member 3 is installed or rotated back to the top end of the introduction port 2, so that the top end of the introduction port 2 is closed, and the drill bit is limited in the shackle.

When the drill bit is disassembled or installed on a drill rod, the drill bit is installed in the drill bit disassembling device, the casing 1 is clamped by the special inclined-mouth tongs for the derrick, the clamping part 5 of the casing 1 clamps the jaw part 61 of the main drill bit, and the drill bit is driven by the special inclined-mouth tongs for the derrick to rotate along with the casing 1, so that the drill bit 6 is assembled and disassembled. The drill bit shackle ware of this embodiment makes the drill bit avoid using the special bevel connection pincers of derrick directly to carry the drill bit rotation at the in-process of dismouting to avoid the drill bit because of receiving the damage that the clamping-force too big leads to, can effectively protect the drill bit not extruded. In addition, some small-sized drill bits cannot be effectively clamped by the inclined jaw pliers special for the derrick due to the fact that the jaw parts are too short, the small-sized drill bits can be installed in the drill bit shackler of the embodiment, and installation or disassembly of the small-sized drill bits is achieved through the shackler.

Preferably, the inner side of the clamping portion 5 is provided with two planes 51 parallel to the axial section of the housing 1, and the two planes 51 are oppositely arranged on two sides of the axial section of the housing 1. When the drill bit 6 is set in the shackler, as shown in fig. 1, the jaw slot 62 of the jaw 61 of the drill bit is engaged with the flat surface 51, so as to restrict the drill bit from rotating relative to the housing 1, and the housing 1 can drive the drill bit 6 to rotate synchronously when rotating.

Preferably, the diameter of the accommodating cavity 11 in the housing 1 is gradually reduced from the closed end to the open end, and the width of the introducing port 2 is gradually reduced from the closed end to the open end of the housing 1. As shown in FIG. 3, the housing 1 has a cylindrical shape, the top end diameter of the accommodating chamber 11 is smaller than the bottom end diameter, and the top end width of the introducing port 2 is smaller than the bottom end width. The thickness of the side wall of the housing 1 is greater at the top end than at the bottom end. The closed end of the housing 1 can restrict the drill bit from moving along the axis of the housing 1. The size of the accommodating cavity 11 and the introduction port 2 is matched with the shape of the drill 6, so that the drill 6 is limited in the shell 1.

Preferably, the housing 1 is provided with two handles 4, and the two handles 4 are symmetrically arranged on two sides of the housing. The handle 4 is arranged on the clamping part 5. Preferably, the handle 4 is of a U-shaped configuration. The handle 4 can facilitate the shackler of the embodiment to be held by hand during carrying.

Preferably, notches 53 are arranged at positions close to the introducing port 2 on two sides of the clamping part 5, the bottom surface of each notch 53 is concave relative to the end surface of the clamping part 5, and a connecting hole or a connecting column is arranged on each notch 53. As shown in fig. 3, two sides of the introducing port 2 are provided with notches 53, and the notches 53 are used for installing the limiting member 3, so that the upper surface of the limiting member 3 and the upper surface of the clamping portion 5 are on the same plane, thereby preventing the limiting member 3 from protruding out of the housing 1 to affect the assembling and disassembling of the drill bit.

Preferably, the limiting member 3 is an arc-shaped plate structure, through holes 31 are respectively formed at two ends of the limiting member 3, and the limiting member 3 passes through the through holes 31 through a pin shaft to be connected to the clamping portion 5 of the housing 1. As shown in fig. 3, the limiting member 3 is connected to the engaging portion 5, so that the jaw portion 61 of the drill bit 6 is engaged with the closed structure formed by the limiting member 3 and the engaging portion 5.

When the notches 53 on the two sides of the clamping part 5 are provided with connecting holes, the limiting part 3 passes through the through hole 31 and the connecting holes through a pin shaft to be connected with the clamping part 5; when the connecting column is arranged on the notch 53, the limiting part 3 penetrates through the through hole 31 to be connected with the clamping part on the connecting column. Both sides of the clamping portion 5 can be provided with connecting holes, or one side of the clamping portion 5 is provided with a connecting hole and the other side is provided with a connecting column, so that the limiting part 3 rotates relative to the clamping portion 5 to open or close the top end of the introducing port 2.

Preferably, the inner side of the clamping portion 5 is further provided with an arc-shaped surface 52, the arc-shaped surface 52 is disposed between the two planes 51, and the arc-shaped surface 52 and the introducing port 2 are disposed on two sides of the clamping portion 5 opposite to each other.
