The nailing machine mounting frame 11 includes a first fixed portion 111 and a first movable portion 112, and the receiving frame 12 includes a second fixed portion 121 and a second movable portion 122. The first movable portion 112 and the second movable portion 122 are respectively telescopically coordinated with the first fixed portion 111 and the second fixed portion 121. A first transmission rod 113 is arranged on the nailing machine mounting frame 11, and a second transmission rod 123 is arranged on the receiving frame 12. The first transmission rod 113 and the second transmission rod 123 are respectively coordinated with the first movable portion 112 and the second movable portion 122. An installation cavity 2 is arranged on the bracket body 1, and a linkage component 21 is arranged in the installation cavity 2. The linkage component 21 drives the first transmission rod 113 and the second transmission rod 123 to rotate synchronously. In this embodiment, a pad for carton stapling is arranged on the carrier frame to ensure the effect of carton stapling.

[0022] By adopting the above technical solution, the length of the nailing machine mounting frame 11 and the receiving frame 12 can be adjusted according to the length of the cardboard. When the cardboard is short, the length of the nailing machine mounting frame 11 and the receiving frame 12 is shortened, which can reduce the space occupied by the bracket. When the cardboard is long, the bracket can also be used, so that the bracket has a wider range of use. The first transmission rod 113 and the second transmission rod 123 can rotate synchronously, ensuring that the nailing machine mounting frame 11 and the receiving frame 12 can be synchronously extended and retracted, so that the nailing machine and the pads on the receiving frame 12 always correspond to each other, so as to ensure the effect of stapling the carton.

[0023] In other embodiments, a slide rail for moving the carton stapler may be provided on the first movable portion 112 to facilitate stapling of cartons.

[0024] In this embodiment, the linkage assembly 21 includes a first gear 211, a second gear 212, and a transmission chain 213. The first gear 211 and the second gear 212 are respectively sleeved on the outer walls of the first transmission rod 113 and the second transmission rod 123. The transmission chain 213 is sleeved on the outer walls of the first gear 211 and the second gear 212, and the transmission chain 213 and the first gear 211 and the second gear 212 are all meshed and matched with each other, so that the power transmission is large and the efficiency is high, thereby ensuring the accuracy of the synchronous extension and retraction of the nailing machine mounting frame 11 and the receiving frame 12. In this embodiment, the second transmission rod 123 is linked to a motor for driving the second transmission rod 123 to rotate.

[0025] In this embodiment, the vertical central axes of the first gear 211 , the second gear 212 , and the transmission chain 213 coincide with each other, and the first gear 211 and the second gear 212 are identical, thereby ensuring the stability of the operation of the linkage assembly 21 .

The outer wall of the transmission portion 1132 is provided with an external thread, so that when the first transmission rod 113 and the second transmission rod 123 rotate, the first movable portion 112 and the second movable portion 122 can be telescopically moved accordingly, thereby realizing flexible adjustment of the nailing machine mounting frame 11 and the receiving frame 12, and ensuring the accuracy and stability of the adjustment.

[0027] In this embodiment, the mounting portion 1131 passes through the first fixed portion 111 and the second fixed portion 121 respectively, the first fixed portion 111 and the second fixed portion 121 are fixedly connected to the bracket body 1, and the mounting portion 1131 is rotatably connected to the bracket body 1, the transmission portion 1132 passes through the first movable portion 112 and the second movable portion 122 respectively, and the bracket body 1 is provided with bearings that are rotatably matched with the first transmission rod 113 and the second transmission rod 123 respectively to ensure the rotation stability of the first transmission rod 113 and the second transmission rod 123. It should be noted that the dividing line between the mounting portion 1131 and the transmission portion 1132 coincides with the end face of the first fixed portion 111 away from the bracket body 1.

[0028] In this embodiment, the first movable part 112 and the second movable part 122 are respectively sleeved on the outer walls of the first fixed part 111 and the second fixed part 121. An extension piece 1121 is provided at one end of the first movable part 112 and the second movable part 122 away from the bracket body 1. The internal thread is located on the inner wall of the extension piece 1121 to ensure the stability of the movement of the first movable part 112 and the second movable part 122.

[0029] In other embodiments, in order to increase the movement stability of the first movable part 112 and the second movable part 122 , structures such as slide rails may be provided on the first fixed part 111 and the second fixed part 121 to cooperate with the first movable part 112 and the second movable part 122 .

[0030] In this embodiment, the first transmission rod 113 and the second transmission rod 123 are both provided with an anti-dropping portion 1133 at one end away from the bracket body 1, which can effectively prevent the first movable portion 112 and the second movable portion 122 from accidentally falling off, thereby ensuring the practicality of the bracket.
