[0023] The positioning assembly includes two mounting plates 13, which are arranged on the outside of the first base rod 2 or the second base rod 3, and a plurality of positioning columns 11 are fixed to one end of each mounting plate 13, and one end of each positioning column 11 passes through the inside of the first positioning groove 14, and a threaded rod 7 passes through the inside of the two mounting plates 13, and the threaded rod 7 passes through the inside of the first through groove 15, and the outer wall of the threaded rod 7 at one end of the mounting plate 13 is sleeved with two threaded sleeves 8, and the outer wall of the threaded sleeve 8 is welded with a pressure plate 12 at one end close to the mounting plate 13;

[0024] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first expansion rod 4 and the second expansion rod 5 are pulled until the mounting plate 6 is in a suitable position, and the first expansion rod 4 and the first base rod 2 and the first through grooves 15 on the second expansion rod 5 and the second base rod 3 are aligned, and then the threaded rod 7 is passed through the first through groove 15, and then the mounting plates 13 are put on both ends of the first through groove 15, and the positioning column 11 is inserted into the first positioning groove 14, and finally the threaded sleeve 8 is screwed on the outer wall of the threaded rod 7, and the pressure plate 12 presses the mounting plate 13 to limit its position, and the displacement between each base rod and the expansion rod is limited by the positioning column 11, thereby achieving a strong connection.

[0025] A plurality of balls are embedded and installed at one end of the pressure plate 12, and an annular groove matching the balls is formed at one end of the mounting plate 13;

[0026] Specifically, Figure 2 As shown, the presence of the ball can reduce the friction between the pressing plate 12 and the mounting plate 13 under high pressure, so that the user can more conveniently drive the threaded sleeve 8 to rotate.

[0027] The second extension rod 5 has guide grooves at both the front and rear ends, and the inner wall of the second base rod 3 is equipped with matching guide bars;

[0028] Specifically, Figure 2 and Figure 3 As shown, such a design can improve the fit and overall strength of the second base rod 3 and the second extension rod 5 .

[0029] One end of the mounting plate 6 is provided with a mounting bar 1, and one end of the mounting plate 6 and the mounting bar 1 are both provided with a second through groove 17, and a plurality of second positioning grooves 16 are evenly distributed on the outer side of the second through groove 17, and the second positioning grooves 16 all run through the inside of the mounting bar 1 and the mounting plate 6, and the second positioning grooves 16 and the first positioning grooves 14 have the same shape and size, and the second through grooves 17 and the first through grooves 15 have the same shape and size;

[0030] Specifically, Figure 1 and Figure 5 As shown, the mounting bar 1 of the device is used to install the wheel. By rotating the mounting bar 1 around the second through slot 17 and then using the positioning assembly to complete the installation between the mounting bar 1 and the mounting plate 6, the height of the end of the mounting bar 1 can be adjusted to adapt to wheels of different diameters.

[0031] A plurality of rotating rods 9 are installed at one end of the mounting plate 13 through a hinge, and an empty slot 19 is passed through the top of the rotating rod 9. A corresponding number of fixing boxes 10 are fixed at one end of the pressing plate 12, and a plurality of spring telescopic rods 21 are fixed at one end of the fixing box 10, and a moving block 20 is installed at one end of the spring telescopic rod 21, and a clamping block 18 is provided at one end of the moving block 20, and the top of the clamping block 18 passes through one end of the empty slot 19, and the bottom end of the clamping block 18 is fixed to one end of the moving block 20 through a fixing member;

[0034] Specifically, Figure 2 and Figure 6 As shown, when the threaded sleeve 8 is tightened, the block 18 can be moved to drive the moving block 20 to overcome the spring telescopic rod 21 and move. Then, the rotating rod 9 is rotated to the maximum stroke, so that the block 18 passes through the empty slot 19. Then, the block 18 is released, and the spring telescopic rod 21 pushes the moving block 20 to reset. The block 18 clamps the rotating rod 9 to limit the rotation of the rotating rod 9. At this time, the mounting plate 13 is pressed down and the positioning is completed by the cooperation of the positioning column 11 and the first positioning groove 14. Therefore, the mounting plate 13 will not shift. At the same time, the rotating rod 9 and the block 18 restrict each other. Therefore, the pressure plate 12 is restricted and cannot rotate. Therefore, the threaded sleeve 8 will not loosen easily.
