[0019] like Figures 1 to 3 The jacks 2 and 3 are respectively arranged on the support frame 2 and the support frame 1 are movable, so that the jacks 2 can be adjusted relative to each other to adjust the load capacity of the pallet.

[0020] In the embodiment, the fixed support seat 2 specifically comprises a middle segment support part 21 and side edge support parts 22 symmetrically arranged on both sides of the middle segment support part 21, the middle segment support part 21 is internally provided with a first cavity 211, the first cavity 211 is symmetrically fixed with connecting parts 212, the first cavity 211 is provided with a bidirectional screw rod 4, both ends of the bidirectional screw rod 4 are respectively rotationally connected to the connecting parts 212 on both sides, both ends of the bidirectional screw rod 4 are respectively provided with outwardly extending threaded parts 41, the threads on the threaded parts 41 on both sides are symmetric to each other, a middle segment connecting rod 5 is arranged between the movable support seat 1 and the middle segment support part 21, one end of the middle segment connecting rod 5 is sleeved on the outer periphery of the threaded part 41 and can form a threaded cooperation with the threaded part 41, and one end of the middle segment connecting rod 5 is fixed to the movable support seat 1, when it is needed to move the movable support seats 1 on both sides towards each other or away from each other to adjust the supporting area of the tray, the middle segment connecting rod 5 sleeved on the threaded parts 41 on both sides and forming a threaded cooperation with the threaded parts 41 can be moved along the direction of the bidirectional screw rod 4 by driving the bidirectional screw rod 4 to rotate, thus the movable support seats 1 on both sides can be moved towards each other or away from each other, wherein the first space is adapted to the cross section of the middle segment connecting rod 5, thus the moving direction of the middle segment connecting rod 5 can be limited during the movement of the middle segment connecting rod 5, and the middle segment connecting rod 5 is prevented from rotating with the bidirectional screw rod 4.

[0021] In addition, the connection between the bidirectional screw rod 4 and the connecting part 212 relies on the bearing 100, that is, the end of the bidirectional screw rod 4 is nested in the inner periphery of the bearing 100 and forms an interference fit, and in addition, in order to facilitate the assembly of the middle segment connecting rod 5, the fixed support seat 2 is composed of two half shells, that is, after the connecting part 212, the middle segment connecting rod 5 and other components are assembled into the first cavity 211, the other half shell is welded and fixed.

[0022] In the embodiment, in order to avoid the influence of the driving structure for driving the bidirectional screw rod 4 to rotate on the supporting of the tray and goods, and in order to facilitate the driving of the bidirectional screw rod 4 to rotate, a driven bevel gear 6 is sleeved and fixed on the outer periphery of the bidirectional screw rod 4, a driving bevel gear 7 is rotationally connected to the inner wall of the middle segment support part 21, the driving bevel gear 7 and the driven bevel gear 6 are meshed with each other, the center of the driving bevel gear 7 is provided with a vertically outwardly extending connecting end 71, the surface of the connecting end 71 is flush with the surface of the middle segment support part 21, so as to ensure that the surface of the tray can be flat, and the connecting end 71 is provided with a downwardly recessed internal hexagonal groove 72, so that a sleeve pipe adapted to the internal hexagonal groove 72 is inserted, and the bidirectional screw rod 4 can be driven to rotate through the sleeve pipe, since the sleeve pipe can prolong the force arm during driving, it is more labor-saving when the bidirectional screw rod 4 is driven to rotate.

[0023] In this embodiment, the connection structure between the side supporting portion 22 and the movable supporting seat 1 is that a second cavity is provided through the side supporting portion 22, and a side connecting rod 8 is provided between the movable supporting seat 1 and the side supporting portion 22. The bottom of the side connecting rod 8 is provided with a connecting groove 81, and a pulley 82 is rotatably connected in the connecting groove 81. The pulleys 82 are multiple and spaced apart from each other. A slide rail 9 is fixed to the inner wall of the side supporting portion 22, and the slide rail 9 is coupled to the pulley 82, and a rolling fit between the two is formed. In this way, when the middle connecting rod 5 moves along the direction of the bidirectional screw 4, it can drive The side connecting rod 8 moves along the direction of the second cavity. In this way, by fixing the side connecting rod 8 and the middle connecting rod 5 to the movable supporting seat 1 at the same time, the stability of the connection of the movable supporting seat 1 and the stability of the force during movement can be improved. In addition, through the arrangement of the pulley 82 and the slide rail 9, the side connecting rod 8 moves along the direction of the second cavity. Since the friction between the pulley 82 and the slide rail 9 is rolling friction, the influence of the friction force on the side connecting rod 8 during movement can be reduced, thereby facilitating the movable supporting seats 1 on both sides to move toward or away from each other.

[0024] In this embodiment, the structure of the side connecting rod 8 moving with the middle connecting rod 5 is that a middle section giving groove 213 and a side giving groove 222 are respectively provided on the middle section supporting part 21 and the side supporting part 22, and a transmission rod 10 is provided between the middle section supporting part 21 and the side supporting part 22. The two ends of the transmission rod 10 extend toward the middle section giving groove 213 and the side giving groove 222 respectively, and are fixed to the middle section connecting rod 5 and the side connecting rod 8 respectively. In this way, power is transmitted by the connecting rod connecting the middle section connecting rod 5 and the side connecting rod 8, so that when the middle section connecting rod 5 moves in the direction of the bidirectional screw 4, the side connecting rod 8 can be driven to move in the direction of the second cavity.

[0025] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
