[0026] When the cantilever support seat is installed, the operator only needs to pull out the positioning pin 301 to unlock, drive the semicircular part 202 to complete a 135° rotation movement through the sliding assembly 203, and make the semicircular part 202 enter the inside of the supporting assembly 2, so that the cantilever support seat can be directly placed between the supporting assemblies 2 without disassembling the rotating shaft, the rotating shaft is synchronously embedded in the inside center of the supporting assembly 2, then the sliding assembly 203 is pushed again to make the semicircular part 202 rotate again by 135° in the reverse direction, so that the positioning slot 304 is aligned with the positioning pin 301, the positioning pin 301 is loosened, and under the pushing of the compression spring 303, the positioning pin 301 is inserted into the inside of the positioning slot 304 again to fix the position of the semicircular part 202.
[0027] As shown in Figure 3 , the outer wall of the semicircular part 202 passes through the inside of the semicircular sliding groove 201, and the outer wall of the semicircular part 202 is in sliding connection with the inner wall of the semicircular sliding groove 201, the outer wall of the semicircular part 202 is closely attached to the inner wall of the semicircular sliding groove 201, the semicircular sliding groove 201 and the semicircular groove 204 are mutually penetrated, and the inner wall of the semicircular groove 204 is in sliding connection with the outer wall of the sliding assembly 203.
[0028] Through the precise cooperation of the semicircular part 202 and the semicircular sliding groove 201, stable sliding is realized. The outer wall of the semicircular part 202 is closely attached to the inner wall of the semicircular sliding groove 201, so as to ensure the stability of the moving track and avoid shaking.
[0029] As shown in Figures 4-5 , the semicircular part 202 has a C-shaped structure as a whole, and the semicircular part 202 can be combined with the supporting assembly 2 to form a complete hollow circular structure.
[0030] When the semicircular part 202 is pushed along the semicircular sliding groove 201 to the working position, the arc-shaped inner wall thereof is seamlessly connected with the corresponding curved surface of the supporting assembly 2 to jointly build a complete annular cavity, thereby providing a firm fixing effect for the cantilever rotating shaft.
[0031] As shown in Figures 4-5 , the semicircular part 202 is provided with a positioning slot 304 at the outer wall end portion away from the sliding assembly 203, one end of the positioning pin 301 passes through the inside of the supporting assembly 2 and extends to the inner wall of the positioning slot 304, and the outer wall of one end of the positioning pin 301 is closely attached to the inner wall of the positioning slot 304.
[0032] By cooperation of the positioning slot 304 and the positioning pin 301, when the positioning pin 301 is inserted into the inside of the positioning slot 304, the semicircular part 202 is fixed.
[0033] As shown in Figure 6As shown, the center of the outer wall of the positioning pin 301 penetrates the center of the inner cavity of the positioning sleeve 3, and the center of the outer wall of the positioning pin 301 is slidably connected to the center of the inner cavity of the positioning sleeve 3.
[0034] After the positioning pin 301 passes through the positioning sleeve 3, it is allowed to slide horizontally along the inner wall of the positioning sleeve 3.
[0035] like Figure 7 As shown, the limiting ring 302 is located on the outer wall of the positioning pin 301 near one end of the semi-circular part 202, and one side of the outer wall of the limiting ring 302 abuts against the inner wall of the positioning sleeve 3.
[0036] By placing the limiting ring 302 at one end of the positioning pin 301, it can prevent the pin from sliding excessively and coming out of the positioning sleeve 3, thus limiting the sliding range of the positioning pin 301.
[0037] like Figure 7 As shown, the outer wall of one end of the compression spring 303 abuts against the outer wall of the limiting ring 302, and the outer wall of the other end of the compression spring 303 is in contact with one end of the inner wall of the positioning sleeve 3.
[0038] When the positioning pin 301 is pulled out by an external force, the spring generates a preload. After the external force is released, the preload can drive the positioning pin 301 back to its original position.
[0039] Working principle: Stable sliding is achieved through the precise fit between the semi-circular part 202 and the semi-circular slide groove 201. The outer wall of the semi-circular part 202 is tightly attached to the inner wall of the semi-circular slide groove 201, ensuring the stability of the movement trajectory and preventing shaking. When the semi-circular part 202 is pushed along the semi-circular slide groove 201 to the working position, its arc-shaped inner wall and the corresponding curved surface of the support component 2 form a seamless connection, jointly constructing a complete annular cavity, providing a reliable fixing effect for the cantilever shaft. Utilizing the mutual cooperation between the positioning slot 304 and the positioning pin 301, when the positioning pin 301 is inserted into the positioning slot 304, ... To achieve a fixing effect on the semi-circular part 202, after the positioning pin 301 passes through the positioning sleeve 3, the positioning pin 301 is allowed to slide horizontally along the inner wall of the positioning sleeve 3. The limiting ring 302 is set at one end of the positioning pin 301 to prevent it from sliding excessively and coming out of the positioning sleeve 3, thus limiting the sliding range of the positioning pin 301. When the positioning pin 301 is pulled out by external force, the spring generates preload. After the external force is released, the preload can drive the positioning pin 301 back to its original position.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
