[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0018] Please refer to Figures 1 to 6The utility model provides a technical scheme: a hard alloy round bar, including round bar main body 1, the detachable setting of round bar main body 1 has sharp head 2, the bottom fixed connection of sharp head 2 has limit stop 4, the outside slide of limit stop 4 is provided with connecting portion 3, the cavity 9 for accommodating sharp head 2 is seted up on round bar main body 1, the outer thread 10 is fixedly connected on the outer wall of round bar main body 1, connecting portion 3 is cooperated with outer thread 10, can realize the installation and disassembly of sharp head 2 and round bar main body 1, when sharp head 2 is upward, connecting portion 3 is pressed tightly limit stop 4 and is connected with round bar main body 1, when sharp head 2 is downward, sharp head 2 will be inserted in cavity 9.

[0019] Wherein, the outside of round bar main body 1 is provided with thread ring 7, the top of connecting portion 3 is provided with connecting groove 8 matched with thread ring 7, the depth of connecting groove 8 is less than the height of thread ring 7, the bottom of connecting portion 3 is fixedly connected with connecting ring 6 matched with thread ring 7, connecting ring 6 is inserted into the inside of thread ring 7, thread ring 7 is internally threaded with connecting groove 8, thread ring 7 is threaded between connecting ring 6, when sharp head 2 is accommodated in cavity 9, connecting groove 8 is threaded with thread ring 7, when the tip of sharp head 2 is outside, connecting ring 6 is threaded with thread ring 7.
