Therefore, the relative motion of the copper pad 31 and the shaft section 23 of the shaft head 2 and the relative motion of the spring 34 and the copper pad 31 are stable whether the actual motion is the relative motion (it should be added that the rectangular spring 34 has a strong rigidity, and the radial deformation of the rectangular spring 34 caused by the friction force applied by the copper pad 31 is negligible).

Example two

As shown in fig. 5 to 9, the second embodiment is the same as the first embodiment in the structure of the lamp holder handle 11, the handle 12 and the spindle head 2, and mainly differs in the pressing assembly 3.

As shown in fig. 5, the end walls at both ends of the rotating shaft section 23 are respectively provided with a positioning groove 232, the positioning groove 232 is internally provided with a copper ring 35 and a second stainless steel pad 36 in sequence from inside to outside, and part of the second stainless steel pad 36 protrudes out of the positioning groove 232; as shown in fig. 9, the pressing assembly 3 includes a second screw 37, the second screw 37 is screwed on the sidewall of the lamp holder handle 11, one end of the second screw 37 is provided with a boss 371, two third stainless steel pads 38 are sequentially sleeved on the boss 371, an elastic ring 39 is disposed between the two third stainless steel pads 38, the elastic ring 39 is preferably made of polyurethane, and the boss 371 sequentially passes through the second stainless steel pad 36 at one end of the rotating shaft section 23 and the inner circle of the copper ring 35, so that the end surface of the third stainless steel pad 38 abuts against the end surface of the second stainless steel pad 36, and the end surface of the second stainless steel pad 36 at the end of the rotating shaft section 23 far from the second screw 37 abuts against the inner wall of the accommodating groove 113.

In this embodiment, after the second screw 37 is screwed into the base handle 11, the force is transmitted to the second stainless steel pad 36 through the third stainless steel pad 38, the friction force between the second stainless steel pad 36 and the copper ring 35 is approximately equal to the friction force between the rotating shaft section 23 of the rotating shaft head 2 and the copper ring 35 (it should be noted that the materials of the rotating shaft head 2 and the second stainless steel pad 36 are the same, and the surface roughness is similar), and the friction force between the second stainless steel pad 36 and the copper ring 35 is smaller than the friction force between the second stainless steel pad 36 and the third stainless steel pad 38 (it should be noted that, under the condition of the same roughness and pressure, the friction force between the copper and the stainless steel is smaller than the friction force between the stainless steels). Because the outside of the copper ring 35 at the pivot section 23 both ends of pivot head 2 all is second stainless steel pad 36, and the frictional force of both sides is all close, and every copper ring 35 all possesses two stable friction pairs, consequently at the pivoted in-process, has stable frictional force. In addition, similar to the first embodiment, the second screw 37 is adjusted to adjust the friction force, i.e. the friction force during the rotation of the lamp holder handle 11.

It should be noted that the base handle 11 is made of a titanium alloy material, and the surface thereof is rough compared to copper and stainless steel materials. Therefore, the friction between the inner wall of the receiving groove 113 of the lamp holder handle 11 and the first stainless steel pad 32 or the second stainless steel pad 36 is greater than the friction between the first stainless steel pad 32 or the second stainless steel pad 36 and the copper ring 35.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
