Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following describes in detail a screw socket torsion testing apparatus and a torsion testing method according to the present invention with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
The invention discloses a screw lamp holder torsion testing device, which comprises a fixed seat 1, a connecting piece 2 and a torsion-adjustable electric screwdriver 3, wherein the fixed seat 1 is provided with a torsion-adjustable electric screwdriver;
the fixed seat 1 is used for fixing a screw lamp holder to be tested;
an external thread 21 is arranged at one end of the connecting piece 2, and the external thread 21 is matched with the thread of the screw socket to be detected; the other end of the connecting piece 2 is provided with a groove 22, and the electric screwdriver 3 with adjustable torque can be embedded into the groove;
