When the first driving mechanism 70 drives the first translation seat 50 and the second translation seat 60 to move vertically, due to the inclined arrangement of the first inclined guide section 91 and the second inclined guide section 92, it can be known from force decomposition that the first guide part 51 and the second guide part 61 make the first translation seat 50 and the second translation seat 60 move horizontally under the abutting action of the groove walls of the guide groove 90; the installation cooperation of guide part and guide way 90 to and the slope setting of oblique guide section realize making translation seat along lateral motion, simple structure, reasonable in design promptly.

Since part of the products 150 do not need to be pushed out during the transportation process of the product area 10, or when no product 150 exists in the product area 10, in order to make the pushing device more flexible to use, the guide groove 90 further comprises an adjusting section 98, and the adjusting section 98 is respectively communicated with the first inclined guide section 91 and the second inclined guide section 92; the pushing device further comprises an adjusting mechanism 110, the guide groove 90 further comprises a first vertical guide section 93 corresponding to the first guide part 51 and a second vertical guide section 94 for the movable insertion of the second guide part 61, and the first vertical guide section 93 and the second vertical guide section 94 are both communicated with one end, close to the first inclined guide section 91, of the adjusting section 98; the adjusting mechanism 110 is used for guiding the first translation seat 50 and the second translation seat 60 to move in the transverse direction so as to cause the first guide portion 51 and the second guide portion 61 to selectively enter the first vertical guide section 93 and the second vertical guide section 94 or the first slant guide section 91 and the second slant guide section 92 respectively. When the product 150 does not need to be pushed out, the adjusting mechanism 110 causes the first guide portion 51 and the second guide portion 61 to correspondingly enter the first vertical guide section 93 and the second vertical guide section 94, and the first translation seat 50 and the second translation seat 60 do not receive the power of transverse movement, that is, only move vertically under the action of the straight guide rod 20, so that the push rod 30 and the lower pressing piece 40 do not push out the product 150; when the product 150 needs to be pushed, the adjusting mechanism 110 causes the first guiding portion 51 and the second guiding portion 61 to correspondingly enter the first inclined guiding section 91 and the second inclined guiding section 92, and the first translation seat 50 and the second translation seat 60 are subjected to the power of transverse movement, that is, the action of pushing out the product 150 is realized, so that the use is more flexible.

Further, the first slant guiding section 91 and the second slant guiding section 92 cooperate to form a slant guiding section group, and the first vertical guiding section 93 and the second vertical guiding section 94 are located on the same side of the slant guiding section group; as shown in fig. 4, the adjustment mechanism 110 includes an adjustment member 111 and a second drive mechanism 112, the adjustment member 111 being mounted in the adjustment segment 98 in a laterally movable manner relative to the adjustment segment 98; the second driving mechanism 112 is used for driving the adjusting piece 111 to move between the first working position and the second working position; when the adjusting piece 111 moves to the first working position, the adjusting piece 111 and the groove wall of the adjusting section 98 are matched to form a first guide opening only right opposite to the first vertical guide section 93 and the second vertical guide section 94; when the adjusting piece 111 moves to the second working position, the adjusting piece 111 is matched with the groove wall of the adjusting section 98 to form a second guide opening only right opposite to the inclined guide section group; the side wall of the adjusting part 111 and the groove wall of the adjusting section 98 guide the movement of the first translation seat 50 and the second translation seat 60, so that the first guide part 51 and the second guide part 61 move transversely under the action of the groove wall and enter the guide openings of the first vertical guide section 93 and the second vertical guide section 94, and the action that the push rod 30 and the lower pressing part 40 do not push out during the vertical movement is realized; when the adjusting member 111 moves to the second working position, the adjusting member 111 cooperates with the groove wall of the adjusting section 98 to form a second guiding opening, and the first and second translation seats 50 and 60 are guided by the side wall of the adjusting member 111 and the groove wall of the adjusting section 98, so that the first and second guiding portions 51 and 61 move transversely under the action of the groove wall and enter the first and second slant guiding sections 91 and 92, the adjusting member 111 has a simple structure, the adjusting manner is convenient, and the guiding efficiency of the adjusting mechanism 110 can be improved.
