Two extension beam mounting arms 2 are respectively fixedly arranged at both ends of one side of the vertical plate 4 for placing the front extension beam 24.

[0029] Reference Figure 2 The positioning assembly is used to position the front extension beam 24, and includes an upper positioning member and a side positioning member. The upper positioning member includes two groups of sleeves 12, each group of sleeves 12 is provided with a plurality of sleeves, and the sleeves 12 are fixedly arranged on the bottom inner wall of the support frame 13 inside the extension beam mounting arm 2, and an upper positioning pin 14 is slidably arranged inside the sleeve 12, and the top end of the upper positioning pin 14 slides through the top of the extension beam mounting arm 2, and a No. 2 compression spring is arranged between the sleeve 12 and the upper positioning pin 14, so that the upper positioning pin 14 remains in an extended state when not subjected to external force, thereby being positioned with the upper part of the front extension beam 24.

[0030] Specifically, after placing the two front extension beams 24 on the two extension beam mounting arms 2, the corresponding upper positioning pins 14 will be inserted into the positioning holes of the front extension beams 24, and the front and rear, left and right sides of the front extension beams 24 will be positioned. The excess upper positioning pins 14 will be squeezed into the interior of the locking sleeve 12, so that they can adapt to the positioning holes of different front extension beams 24.

[0031] The side positioning parts include two No. 2 cylinders 8, which are respectively fixed on both sides of the top of the cylinder bracket 7. The output end of the No. 2 cylinder 8 is fixedly sleeved with a limit sleeve 9, and the end of the limit sleeve 9 away from the No. 2 cylinder 8 is fixedly provided with a push plate 11, and the side of the push plate 11 away from the No. 2 cylinder 8 is fixedly provided with a plurality of side positioning pins 10, and one end of the side positioning pin 10 slides through the outside of the extension beam mounting arm 2. Through the extension and retraction of the No. 2 cylinder 8, the push plate 11 and the side positioning pin 10 are pushed to move, thereby positioning with the side of the front extension beam 24.

[0032] Specifically, the second cylinder 8 drives the limit sleeve 9 to move, the limit sleeve 9 drives the push plate 11 to move, and the push plate 11 drives the side positioning pins 10 to move, so that multiple side positioning pins 10 are inserted into the corresponding positioning holes on the side of the front extension beam 24, and the upper and lower parts of the front extension beam 24 are positioned, and then the second cross beam 23 and the first cross beam 22 and the remaining parts can be installed for reference.
