## Abstract

The disclosure discloses a universal supporting mechanism, comprising a lifting platform for fixing lifting equipment and a connecting seat, and further comprising a universal ball head fixedly connected with the lifting platform, with the universal ball head movably connected with the connecting seat via a connector. The disclosure does not need to be adjusted separately by two or more angle adjustment mechanisms, the angle adjustment can be achieved in one step, the structure is simple, and the application range is wide.

## Claims

### Claim 1

A universal supporting mechanism for fixing a gun barrel, comprising:
a lifting platform having a universal ball head fixedly connected with the lifting platform, with the universal ball head movably connected with a connecting seat via a connector;
wherein the connecting seat has a recess, the recess has a first through hole, the universal ball head has a second through hole, and the connector passes through the second through hole and the first through hole in sequence and holds the universal ball head at a connection between the connector and the second through hole;
wherein the connector has a central shaft, a first end of the central shaft has a limiting portion;
wherein the limiting portion is a cylinder, a portion of the second through hole that contacts the limiting portion has a curved surface, and the curved surface forms a surface contact with a side surface of the cylinder of the limiting portion;
wherein a middle part of the central shaft has a positioning protrusion, which is inserted and positioned cooperatively within a groove on a fixing member located below the recess; the fixing member is sleeved in the connecting seat.

### Claim 2 (depends on 1)

The universal supporting mechanism according to claim 1, wherein the limiting portion holds the universal ball head at a connection between the limiting portion and the second through hole.

### Claim 3 (depends on 2)

The universal supporting mechanism according to claim 2, wherein an outer surface of the universal ball head is in surface contact with an inner surface of the recess.

### Claim 4 (depends on 1)

The universal supporting mechanism according to claim 1, wherein an outer surface of the fixing member abuts against an inner wall of the connecting seat.

### Claim 5 (depends on 4)

The universal supporting mechanism according to claim 4, wherein an outer surface of the universal ball head is in surface contact with an inner surface of the recess.

### Claim 6 (depends on 1)

The universal supporting mechanism according to claim 1, wherein a second end of the central shaft is connected with an adjusting knob.

### Claim 7 (depends on 1)

The universal supporting mechanism according to claim 1, wherein an outer surface of the universal ball head is in surface contact with an inner surface of the recess.
