After adjusting the height of the second telescopic joint 22, the locking member 25 is inserted into the cavity, and the locking member 25 drives the pushing sleeve 62 to simultaneously push the first wedge block 52 and the second wedge block 53 away from each other, so that the first fastener 45 is inserted into the limiting hole 46 and pressed against the truss main pipe 7, and the second fastener 50 is inserted into the fixing member 34, thereby further positioning the first rotating assembly 1 and the second rotating assembly 3, which helps to achieve a better positioning effect.

[0055] Example 2:

[0056] Reference Figure 6 and Figure 7 The difference between the embodiment of the present application and embodiment 1 is that the fixing member 34 in this embodiment is specifically a latch, and a clamping plate 80 is slidably mounted on the first connecting member 31 on both sides of the fixing member 34. A clamping groove 81 is provided on the side wall of the first connecting member 31, and the clamping plate 80 is slidably mounted in the clamping groove 81. The clamping plate 80 is used to clamp and lock the fixing member 34. The top of the second fastener 50 is provided with a driving assembly 8 that drives the clamping plates 80 to approach each other. The driving assembly 8 includes a mounting plate 82 and a push plate 83. The mounting plate 82 is fixed to the top of the second fastener 50. The mounting plate 82 is an arc-shaped plate, and the lowest point of the arc-shaped plate is arranged toward the first connecting plate 311, so that the arc-shaped plate can give way to the fixing member 34 when lifting or lowering. The push plate 83 is fixed to the side wall of the mounting plate 82 facing the fixing member 34. The push plate 83 is arranged on the side of the clamping plate 80 facing away from the fixing member 34. The push plate 83 is inclined toward the side wall of the clamping plate 80, and the distance between the push plate 83 and the clamping plate 80 gradually increases along the side away from the mounting plate 82. A clamping block 84 is fixed to the side wall of the clamping plate 80 facing the push plate 83. The clamping block 84 is specifically a dovetail block. The side wall of the push plate 83 facing the clamping plate 80 is provided with a clamping slot 85. The clamping slot 85 is specifically a dovetail slot. The clamping block 84 is slidably mounted in the clamping slot 85.

[0057] Reference Figure 5 and Figure 7When the locking member 25 is inserted into the cavity, the push sleeve 62 pushes the second wedge 53 upward, thereby driving the mounting plate 82 upward. The mounting plate 82 then drives the clamping plates 80 on either side of the fixing member 34 toward each other, causing the clamping plates 80 to clamp and lock the fixing member 34. The fixing sleeve on the fixing member 34 is equipped with multiple retaining rings 86, and the clamping plates 80 are provided with fastening grooves 87. The fastening grooves 87 are trapezoidal grooves that gradually decrease in size away from the retaining rings 86. As the clamping plates 80 on either side approach each other, the clamping force on the retaining rings 86 becomes tighter as the fastening grooves 87 decrease in size, thereby achieving a better clamping effect. After the locking member 25 is removed from the cavity, the second wedge 53 descends, driving the mounting plate 82 and the push plate 83 on the mounting plate 82 downward. The push plate 83 drives the clamping plates 80 on either side of the fixing member 34 away from each other, causing the clamping plates 80 to release the fixing member 34, facilitating removal.

[0058] The working principle of the embodiment of the present application is as follows: the locking member 25 is inserted into the cavity, so that the push piece 65 pushes the push sleeve 62, thereby causing the push sleeve 62 to push the first wedge block 52 and the second wedge block 53 away from each other. The second wedge block 53 drives the second connecting bar 42 and the mounting plate 82 to rise. Under the action of the push plate 83, the clamping plates 80 on both sides of the fixing member 34 are moved closer to each other, and the clamping plates 80 clamp the fixing member 34, thereby locking the fixing member 34. When the locking member 25 is removed, the mounting plate 82 and the second connecting bar 42 descend, driving the push plate 83 to descend. Due to the engagement of the locking groove 85 with the clamping block 84, the clamping plates 80 on both sides are driven away from each other, so that the clamping plates 80 release the fixing member 34, thereby unlocking the fixing member 34.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
