Background
The cutting pick is used as an important cutter of a coal mining machine for crushing coal rocks, and the performance of the cutting pick directly influences the productivity, the working reliability and the service life of the coal mining machine. The cutting pick can be impacted by load in the process of contacting with the coal rock, and hard minerals (such as gangue, quartz and pyrite) can be encountered under complicated and severe working conditions. Meanwhile, the cutting pick can fail due to high temperature generated on the surface of the cutting pick caused by friction, corrosion, impact and the like. After the cutting teeth are worn, broken, lost and other failure conditions, the roller of the coal mining machine mainly cuts the coal rock mass by means of the cutting tooth body, the tooth holder extrusion and the like, so that the dust amount is increased, and the more serious the cutting tooth is worn, the more and more the dust is generated. Therefore, damage often occurs during use and must be replaced after damage. The existing cutting pick is usually of an integrated structure and is installed on a tooth holder through a gasket, and when the head of the cutting pick is worn, the whole cutting pick needs to be replaced, so that the damage is large, and the replacement cost is high.

Detailed Description
The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.
As shown in fig. 1 to 4, a mining pick of the present embodiment includes a pick body 1 and a shank 2, and the pick body 1 and the shank 2 are connected. Tooth body 1 includes first end 11 and second end 12, and first end 1 is equipped with alloy head 3, and second end 12 is equipped with locating lever 4 and locating piece 5, and locating lever 4 protruding is established at second end 12, locating piece 5 has a plurality ofly, and a plurality of locating piece 5 interval sets up. The tooth handle 2 is provided with a matching surface 6 and a mounting hole 7, the matching surface 6 is arranged at the end part of the tooth handle 2, the matching surface 6 is provided with a positioning groove 61, the positioning groove 61 is arranged corresponding to the positioning block 5, and the positioning rod 4 is inserted in the mounting hole 7. The side surface of the gear handle 2 is provided with a limiting hole 21, the limiting hole 21 is arranged corresponding to the positioning hole 41 on the positioning rod 4, the side surface of the gear handle 2 is provided with a screw 8, and the screw 8 penetrates through the limiting hole 21 and the positioning hole 41. In the technical scheme, the tooth body 1 and the tooth handle 2 can be connected through the insertion between the positioning rod 4 and the mounting hole 7; through the matching between the positioning groove 61 and the positioning block 5, the tooth body can be positioned conveniently, and when the cutting tooth rotates, the tooth body 1 and the tooth handle 2 are prevented from rotating relatively. By providing the screw 8, the tooth body 1 and the tooth shank 2 can be fixedly connected.
