Detailed Description

Referring to fig. 1-5, a simple welding fixture for a diamond drill bit includes a base 1, the base 1 is fixable on the ground, the base 1 includes a saddle 13 and a support frame 14 distributed around the saddle 13, the support frame 14 is provided with a through hole, and a spike can pass through the through hole to connect with the ground when the support frame 14 is connected with the ground.

Be equipped with telescopic link 2 on the

base
