[0005] The special cantilever pan / tilt connection structure includes an axis, an inclined column connecting sleeve, a positioning switch, a locking ring, a connecting screw, and a locking knob; the axis is connected to the locking knob through the inclined column connecting sleeve and the locking ring, wherein the connecting screw is connected to the locking knob, and the other end of the locking knob is connected and fixed with the axis thread; wherein a positioning switch is arranged between the axis and the inclined column connecting sleeve, and comprises a round nut, a pin convex step, a positioning groove, an axis groove, a hole, and a spring; the round nut and the pin convex step screw are connected to each other. The convex step of the pin rod is connected by a wire, and the other end of the convex step of the pin rod is contacted and connected with the spring through a positioning groove, an axis groove, and a hole. The convex step of the pin rod matches the axis groove and the positioning groove. The spring pushes the convex step of the pin rod to slide up and down in the axis groove and the positioning groove. When the positioning switch is turned on, the tilt column pitches from 0 to 45°, 90°, and 180°. The tilt column is rotated 180° and is inverted between the two legs of the tripod. There is no need to disassemble the cantilever head. The tilt column is 90° to the horizontal plane of the base. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0010] The following will be combined Figure 1 , Figure 2 , Figure 3 , the accompanying drawings illustrate the present invention in detail.

[0011] The special cantilever pan / tilt connection structure of the present invention comprises an inclined column 1, a base 2, a positioning switch 3, a transfer platform 11, and a tension knob 12; the transfer platform 11 is arranged at the upper side end of the inclined column 1, and is suitable for installing and fixing photographic equipment, wherein the other side end of the inclined column 1 is provided with a tension knob 12; the base 2 is arranged at the side end of the inclined column connecting sleeve 13, and is used to support the inclined column 1, and the side end of the base 2 is provided with an axis 22, and the lower middle part of the base 2 is provided with a tripod connecting screw 21 connected to the tripod base; wherein,

[0012] The special cantilever pan / tilt connection structure includes an axis 22, an inclined column connection sleeve 13, a positioning switch 3, a locking ring 25, a connecting screw 24, and a locking knob 26; the axis 22 is connected to the locking knob 26 through the inclined column connection sleeve 13 and the locking ring 25, wherein the connecting screw 24 is connected to the locking knob 26, and the other end of the connecting screw 24 is threadedly connected and fixed to the axis 22; wherein a positioning switch 3 is arranged between the base 2 and the inclined column connection sleeve 13, and includes a round nut 35, a pin convex step 31, a positioning groove 14, an axis groove 23, a hole 33, and a spring 32; the round nut 3 5 is connected with the pin convex step screw 34, and the other end of the pin convex step 31 is in contact with the spring 32 through the positioning groove 14, the axis groove 23, and the hole 33. The pin convex step 31 matches the axis groove 23 and the positioning groove 14. The spring pushes the pin convex step 31 to slide up and down in the axis groove 23 and the positioning groove 14. Turn on the positioning switch 3 and the tilt column 1 pitches from 0 to 45°, 90°, and 180°. The tilt column 1 is rotated 180° and stands upside down between the two legs of the tripod. There is no need to disassemble the cantilever head; wherein the tilt column 1 is 90° to the horizontal plane of the base 2.
