[0027] In the initial state, the insertion rod 209 is inserted into the positioning hole 206, and the spring 207 is in a compressed state. First, the U-shaped frame 201 and the U-shaped plate 202 are moved to change the distance between the mounting frame one 1 and the mounting frame two 4. When the U-shaped frame 201 and the U-shaped plate 202 are moved to the end, the sliding block 208 is then slid along the inner rod 205 and approaches the sleeve 2012. At this time, the spring 207 is compressed again, and the side disc 2010 is driven to move through the connecting column 2011. Until the insertion rod 209 is removed from the positioning hole 206, the connecting column 2011 is then rotated, the insertion rod 209 is driven to rotate through the side disc 2010, the insertion rod 209 penetrates through the through hole 2014 and is inserted into the corresponding insertion hole 2013 under the elastic force of the spring 207, the U-shaped frame 201 and the U-shaped plate 202 are fixed, and finally the length of the whole frame is adjusted.

[0029] In use, first rotate the two hand wheels 303 to rotate the two sleeves 304. Since the two sleeves 304 are both threaded on the outside of the screw rod 302, the two sleeves 304 move along the length of the screw rod 302 while rotating until the two sleeves 304 abut the inner and outer sides of the U-shaped frame 301, respectively, to firmly connect the mounting frame one 1 and the mounting frame two 4, and finally improve the strength of the entire frame.
