Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] like Figure 1 and Figure 2 and Figure 3 As shown, a linkage-type variable pitch frame for a double-sided machine includes a first telescopic component 1, a second telescopic component 2, and a support component 3. The first telescopic component 1 and the second telescopic component 2 are slidably disposed on the support component 3.

[0019] The support assembly 3 includes a first support rod 31, a second support rod 32, and a bearing plate 33. The first support rod 31 and the second support rod 32 are arranged side by side with intervals between them. The bearing plate 33 is slidably disposed on the first support rod 31 and the second support rod 32. The bearing plate 33 is used to support other equipment.

[0020] The first telescopic component 1 includes two sets of first connecting plate group 11 and second connecting plate group 12 connected end to end. The first connecting plate group 11 and the second connecting plate group 12 form a retractable parallel quadrilateral structure. The top of the first telescopic component 1 is connected to the top of the first support rod 31, and the bottom of the first telescopic component 1 is connected to the first end of the bearing plate 33.

[0021] The second telescopic component 2 includes two sets of third connecting plate groups 23 and fourth connecting plate groups 24 connected end to end. The third connecting plate group 23 and the fourth connecting plate group 24 form a retractable parallelogram structure. The top of the second telescopic component 2 is connected to the top of the second support rod 32, and the bottom of the second telescopic component 2 is connected to the second end of the bearing plate 33.

[0022] If the height of the bearing plate 33 needs to be adjusted, the first connecting plate group 11 and the second connecting plate group 12 will act as a buffer, so that the bearing plate 33 will not fall off the first support rod 31 or the second support rod 32 all at once. The first support rod 31 or the second support rod 32 will also guide the bearing plate 33.

[0023] The support plate 33 includes an integrally formed first side plate 331, second side plate 332 and bottom plate 333. The bottom plate 333 is connected to the first side plate 331 and the second side plate 332 at both ends. The bottom end of the first telescopic component 1 is connected to the first side plate 331, and the second telescopic component 2 is connected to the second side plate 332. The bottom plate 333 is located between the first side plate 331 and the second side plate 332, and the bottom plate 333 is used to support other equipment.

[0024] The support assembly 3 also includes a first lower slider 35 and a second lower slider 36. The first lower slider 35 is disposed on the first side plate 331, and the second lower slider 36 is disposed on the second side plate 332. The first lower slider 35 is slidably disposed on the first support rod 31, and the second lower slider 36 is slidably disposed on the second support rod 32.

[0025] In this example, two first support rods 31 are provided, and the first lower slider 35 is slidably mounted on the two first support rods 31. This makes the sliding of the first lower slider 35 on the two first support rods 31 more stable and less prone to tilting. Correspondingly, the sliding of the first side plate 331 is more stable and less prone to tilting.

[0026] Two second support rods 32 are provided, and the second lower slider 36 is slidably mounted on the two second support rods 32. In this way, the second lower slider 36 slides more stably on the two second support rods 32, and the second lower slider 36 is not easy to tilt. Correspondingly, the second side plate 332 slides more stably and is not easy to tilt.

[0027] The support assembly 3 also includes a plurality of first screws 351 and a plurality of second screws 361. The first support rod 31 passes through the first lower slider 35, and the second support rod 32 passes through the second lower slider 36. The plurality of first screws 351 are rotatably mounted on the first lower slider 35, and the plurality of second screws 361 are rotatably mounted on the second lower slider 36. The first support rod 31 is located on the movement path of the first screw 351, and the second lower slider 36 is located on the movement path of the second screw 361.

[0028] Rotating the first screw 351 and the second screw 361 allows the end of the first screw 351 to move away from or abut against the first support rod 31, and the end of the second screw 361 to move away from or abut against the second support rod 32. When it is necessary to adjust the height of the base plate 333, first rotate the first screw 351 and the second screw 361 so that the end of the first screw 351 moves away from the first support rod 31 and the end of the second screw 361 moves away from the second support rod 32. In this way, the base plate 333, which is in a relaxed state, can rise or fall. After the base plate 333 moves to the set position, rotate the first screw 351 and the second screw 361 again so that the end of the first screw 351 abuts against the first support rod 31 and the end of the second screw 361 abuts against the second support rod 32.

[0029] The support assembly 3 also includes a first upper slider 37 and a second upper slider 38. The first upper slider 37 is slidably disposed on the first support rod 31, and the second upper slider 38 is slidably disposed on the second support rod 32. The top of the first telescopic assembly 1 is connected to the first upper slider 37, and the second telescopic assembly 2 is connected to the second upper slider 38.

[0030] The first upper slider 37 is slidably disposed on the upper part of the two first support rods 31. The position of the first upper slider 37 on the two first support rods 31 is determined according to the length of the first telescopic component 1. The second upper slider 38 is slidably disposed on the upper part of the two second support rods 32. The position of the second upper slider 38 on the second support rods 32 is determined according to the length of the second telescopic component 2.

[0031] The support assembly 3 also includes a plurality of third screws 371 and a plurality of fourth screws 381. The third screws 371 are rotatably mounted on the first upper slider 37, and the fourth screws 381 are rotatably mounted on the second upper slider 38. The first support rod 31 passes through the first upper slider 37, and the second support rod 32 passes through the second upper slider 38. The first support rod 31 is located on the movement path of the third screw 371, and the second support rod 32 is located on the movement path of the fourth screw 381.

[0032] Rotate the third screw 371 and the fourth screw 381. The third screw 371 can press against or move away from the first support rod 31, and the fourth screw 381 can press against or move away from the second support rod 32. When it is necessary to adjust the position of the first upper slider 37 and the second upper slider 38, rotate the third screw 371 and the fourth screw 381 so that the end of the third screw 371 moves away from the first support rod 31 and the end of the fourth screw 381 moves away from the second support rod 32, so that the first upper slider 37 and the second upper slider 38 are in a relaxed state. Then adjust the position of the first upper slider 37 and the second upper slider 38. After the position of the first upper slider 37 and the second upper slider 38 is determined, rotate the third screw 371 and the fourth screw 381 again so that the end of the third screw 371 presses against the first support rod 31 and the end of the fourth screw 381 presses against the second support rod 32.
