Referring to fig. 1 and 2, an embodiment of a connection device is provided, which includes a first fixing member 1, a club 6, a second fixing member 3, and a limiting member 5.

The first fixing piece 1 is provided with a first universal ball 2 which is movably arranged, and the first universal ball 2 is provided with a ball hole. The ball arm 6 passes through the ball hole, and the ball arm 6 can slide in the ball hole relative to the first universal ball 2. The second universal ball 4 that the activity set up is installed on the second mounting 3, and the second universal ball 4 is connected to the one end of club 6, and the other end at club 6 is connected to locating part 5, and locating part 5 is used for preventing club 6 from deviating from in the ball hole.

As shown in fig. 3 and fig. 4, the connecting device can be applied to a lamp, the lamp comprises a lamp body 15 and a base 14, when the connecting device is used, the first fixing piece 1 can be connected with the base 14, the second fixing piece 3 can be installed in the lamp body 15, and for convenience in connection, a hole site can be formed in the joint surface of the lamp body 15 and the base 14, so that the connecting device can conveniently pass through.

The joining surfaces are generally plane surfaces or arc surfaces, and the curvature is the same, so that the joining surfaces can keep an inherent distance or joint with each other at any relative position during relative movement.

The abutting surface of the lamp body 15 and the abutting surface of the base 14 may be planar and mutually abutting, and the abutting surface of the lamp body 15 moves relative to the abutting surface of the base 14, because the abutting surface is planar and moves linearly at this time, the irradiation direction changes when the position of the lamp body 15 changes. When the butt joint surface of the lamp body 15 moves, the second fixing piece 3 moves, the first universal ball 2 and the second universal ball 4 rotate, the ball rod 6 swings, the ball rod 6 can slide in the ball hole, the relative movement form between the two butt joint surfaces can be completely matched, and the two butt joint surfaces still keep a joint state in the moving process.

As shown in fig. 4, the mating surface of the lamp body 15 and the mating surface of the base 14 may be arc surfaces, and the two arc surfaces are mutually bonded, so that the two mating surfaces relatively move, and move along the extending direction of the arc surfaces, thereby realizing the direction conversion of the lamp body 15. By rotating the first universal ball 2 and the second universal ball 4, the swing of the ball arm 6 and the sliding of the ball arm 6 from the ball hole can adapt to the moving form, so that the two butt joint surfaces still keep the joint state when moving along the extending direction of the arc surface.

The function of the stop 5 is to prevent the cue stick 6 from sliding out of the hole, and the stop 5 may be a nut having a diameter larger than the diameter of the hole.

In addition, the device has high degree of freedom, so that the joint surface of the lamp body 15 can move and adjust along all directions relative to the joint surface of the base 14, and the joint state is still unchanged. Whereas the prior art connection forms are not able to adapt to this positional adjustment in all directions.

It should be noted that, the first universal ball 2 and the second universal ball 4 can rotate only when overcoming a certain friction force, so that when the user does not actively drive the lamp body 15 to move, both do not rotate. Similarly, the club 6 slides through the ball hole, and friction is generated between the club and the ball hole, so that the club 6 cannot slide actively under the condition that the user does not drive the lamp body 15 to move actively.

Therefore, only under the gravity of the lamp body 15, the two universal balls and the ball arm 6 can not actively rotate or slide, and the lamp body 15 can be kept in a static state under the static friction force state.

Therefore, the connecting device provided by the embodiment has high degree of freedom, can adapt to the relative movement of the two opposite joint surfaces under the condition that the joint state interval is kept unchanged, and can also keep the attractive appearance and compactness of the lamp body 15.

As shown in fig. 1, further, the first universal ball 2 is in ball joint with the first fixing piece 1, and the second universal ball 4 is in ball joint with the second fixing piece 3.

It will be appreciated that, to increase the stability, the first universal balls 2 may be three and uniformly distributed on the first fixing member 1 at intervals along the circumferential direction, the second universal balls 4 may be three and uniformly distributed on the second fixing member 3 at intervals along the circumferential direction, and the clubs 6 may be three, each club 6 passing through one first universal ball 2 and correspondingly connected to one second universal ball 4.

The three spheres and the three clubs 6 reduce the materials to the maximum extent under the condition of keeping stable, can save cost and processing procedures, and do not influence the use effect.

The first universal ball 2 and the second universal ball 4 are uniformly arranged along the circumferential direction, so that the symmetrical effect is realized, and the adjusting effect is better.
