The connecting arms 3 are connected to the legs 2 through an angle adjustment mechanism. The angle between the connecting arms 3 and the legs 2 is adjusted through the angle adjustment mechanism, thereby adjusting the height and level of the support frame. In specific applications, weapons and equipment are installed on the support frame of this structure, which is convenient for adjusting the height and level of the weapons and equipment.

[0019] As a preferred structure, Figure 3 , 4 As shown, a double-ear seat 4 is provided at the end of the connecting arm 3, and a single-ear seat 5 matched with the double-ear seat 4 is provided at the upper end of the frame leg 2. The angle adjustment mechanism includes a handle 6, a main shaft 7, an inner toothed disc and an outer toothed disc 9 that can mesh with each other. The inner toothed disc 8 and the outer toothed disc 9 are two sets, and the two inner toothed discs 8 are respectively arranged in the grooves on both sides of the single-ear seat 5, and the two outer toothed discs 9 are correspondingly arranged in the two through holes of the double-ear seat 4, and the outer convex eaves of the outer toothed disc 9 are close to the outer wall of the double-ear seat 4; the matching surfaces of the inner toothed disc 8 and the outer toothed disc 9 are provided with teeth 10 that can mesh with each other, and a disc spring 11 is provided between the inner toothed disc 8 and the outer toothed disc 9, and the inner sides of the end surfaces on the opposite sides of the inner toothed disc 8 and the outer toothed disc 9 are provided with an annular groove 12 for accommodating the disc spring 11. The specific structure is as shown in FIG. Figure 5-9 As shown; the spindle 7 passes through the outer toothed disc 9, the inner toothed disc 8 and the middle through hole of the single ear seat 5, one end of the spindle 7 is fixed on the cover plate 13 outside the outer toothed disc 9, and the other end of the spindle 7 is threadedly matched with the mounting hole at the end of the handle 6. The two inner toothed discs 8 are symmetrically installed in the annular grooves 12 on both sides of the single ear seat 5, and the two outer toothed discs 9 are symmetrically installed in the two through holes of the double ear seat 4, and then the threaded end of the spindle 7 passes through the single ear seat 5, the inner toothed disc 8 and the outer toothed disc 9 and is connected to the handle 6. Turning the handle 6 can make it move outward along the spindle 7, and the inner toothed disc 8 and the outer toothed disc 9 can be separated under the action of the disc spring 11, which is convenient for adjusting the angle between the frame leg and the connecting arm. The height and horizontality of the support can be adjusted by rotating the three frame legs; when the frame legs are adjusted, the handle 6 is rotated in the opposite direction, and the disc spring 11 can be compressed to make the tooth shape of the outer toothed disc 9 and the inner toothed disc 8 bite and fix, so as to realize the locking of the connecting arm 3 and the frame leg 2. The inner gear disc 8 and the outer gear disc 9 are engaged or released by rotating the handle 6 , thereby achieving relative fixation and rotation between the connecting arm 3 and the frame leg 2 .
