A straight guiding device 2 is arranged on the frame through a guiding seat connecting plate 200. The specific setting method is as follows: a guiding seat connecting plate 200 is arranged on the frame. The straight guiding device 2 includes: a straight guiding seat composed of a guiding bottom plate 20 arranged on the guiding seat connecting plate 200, and a pair of guiding ear plates 21 and 22 arranged at the same-side two ends of the guiding bottom plate 20. A pair of parallel guiding rods 25 and 26 are arranged on the guiding ear plates 21 and 22, that is: both ends of the guiding rod 25 are respectively arranged in the guiding ear plates 21 and 22 in a one-to-one correspondence, and both ends of the guiding rod 26 are respectively arranged in the guiding ear plates 21 and 22 in a one-to-one correspondence. An electric cylinder 1 with its driving rod parallel to the guiding rods 25 and 26 is arranged on the outer side of the guiding ear plate 22. After the driving rod of the electric cylinder 1 passes through the guiding ear plate 22, a push plate 30 is arranged. The push plate 30 is movably inserted on the pair of guiding rods 25 and 26. A first gear push shaft 31 is arranged on the side of the push plate 30 and the corresponding guiding ear plate 21 close to the first push rod seat 5, and a second gear push shaft 32 is arranged on the other side. The first gear push shaft 31 and the second gear push shaft 32 are parallel to the pair of guiding rods 25 and 26 and are located outside the pair of guiding rods 25 and 26 (the pair of guiding rods 25 and 26 are located between the first gear push shaft 31 and the second gear push shaft 32). A first push shaft strip tooth 311 is arranged on the side of the first gear push shaft 31 facing the first push rod seat 5. The corresponding end of the second gear push shaft 32 ( Figure 1 and Figure 2The left end of the first push rod 51 passes through the straight guiding device 2 (the guiding ear plate 21 on the left side). A second push rod bar-shaped tooth 321 is arranged on the side facing the second push rod seat 6; on the first push rod seat 5, a first push rod driven shaft 53 and a first push rod transmission shaft 55 are sequentially arranged along the direction perpendicular to the first push rod 51 between the first push rod 51 and the first gear push shaft 31. A transmission gear 551 meshing with the first push rod bar-shaped tooth 311 is arranged on the first push rod transmission shaft 55. A first driven gear 531 meshing with the transmission gear 551 on the first push rod transmission shaft 55 and a second driven gear corresponding to the first push rod 51 are arranged on the first push rod driven shaft 53. A first push rod bar-shaped tooth 511 meshing with the second driven gear on the first push rod driven shaft 53 is arranged on the first push rod 51; on the second push rod seat 6, a second push rod driven shaft 63, a cross-over gear shaft 64 and a second push rod transmission shaft 65 are sequentially arranged along the direction perpendicular to the second push rod 61 between the second push rod 61 and the second gear push shaft 32. A transmission gear 651 meshing with the second push rod bar-shaped tooth 321 is arranged on the second push rod transmission shaft 65. A cross-over gear 641 meshing with the transmission gear 651 on the second push rod transmission shaft 65 is arranged on the cross-over gear shaft 64. A first driven gear 631 meshing with the cross-over gear 641 and a second driven gear corresponding to the second push rod 61 are arranged on the second push rod driven shaft 63. A second push rod bar-shaped tooth 611 meshing with the second driven gear on the second push rod driven shaft 63 is arranged on the second push rod 61.
[0019] The working principle of the present utility model is as follows: When driving the first push rod 51 and the second push rod 61 to move closer to each other in the middle, the driving rod of the electric cylinder 1 extends forward. The driving rod of the electric cylinder 1 drives the first gear push shaft 31 and the second gear push shaft 32 to move synchronously through the push plate 30 sliding on a pair of guide rods 25 and 26. The first push shaft strip teeth 311 on the first gear push shaft 31 push the transmission gear 551 on the first push rod transmission shaft 55 to rotate clockwise. The transmission gear 551 on the first push rod transmission shaft 55 pushes the first driven gear 531 on the first push rod driven shaft 53 to rotate counterclockwise. The second driven teeth on the first push rod driven shaft 53 rotate counterclockwise together with the first driven gear 531 on the first push rod driven shaft 53 and push the first push rod 51 to move leftward through the first push rod strip teeth 511. At the same time, the second push shaft strip teeth 321 on the second gear push shaft 32 push the transmission gear 651 on the second push rod transmission shaft 65 to rotate clockwise. The transmission gear 651 on the second push rod transmission shaft 65 pushes the idler gear 641 to rotate counterclockwise. The idler gear 641 pushes the first driven gear 631 on the second push rod driven shaft 63 to rotate clockwise. The second driven teeth on the second push rod driven shaft 63 rotate clockwise together with the first driven gear 631 on the second push rod driven shaft 63 and push the second push rod 61 to move rightward through the second push rod strip teeth 611, thus realizing the reverse and equal-distance movement of the first push rod 51 and the second push rod 61. When driving the first push rod 51 and the second push rod 61 to move apart to both sides, it only needs to retract the driving rod of the electric cylinder 1, which will not be elaborated here.
