After the combination rod 134 spirally enters the rotating drum 1144 to a certain depth, the stepper motor 1152 is turned off, and the thin screw fixedly arranged at the bottom of the limit rod 133 is assembled with the hexagonal nut thread to prevent the limit rod 133 from slipping.

[0032] When the device is started, the hydraulic cylinder device 144, the stepper motor 1152 and the oil pump device 142 are started, and in conjunction with the mobile forklift body with a vehicle-mounted hydraulic lifting device, the hydraulic cylinder device 144 drives the fixing fixture 1 to expand outward along the left and right ends until the top of the vertical plate 12 contacts and fits with the bottom of the preset anchor frame 23, and the vertical plate 12 contacts and fits with the reinforcement plate 22. The stepper motor 1152 starts in the forward direction, driving the driving gear 1153 and the driven gear 1146 to engage and rotate, thereby driving the rotating drum 1144 to rotate, so that the inner wall thread of the rotating drum 1144 and the lower screw thread of the combination rod 134 are rotated, and the combination rod 134 spirals downward into the interior of the rotating drum 1144 until the bottom end of the T-plate 132 contacts and fits with the inner wall of the bottom end of the preset anchor frame 23, thereby clamping and fixing the container 2. At this time, the stepper motor 1152 is turned off.

[0033] The flexible tube fixedly connected to the top of the upper box 1121 is fixedly connected to the inner wall of the rear end of the oil filter cartridge 1161, the flexible tube fixedly connected to the bottom end of the oil filter cartridge 1161 is fixedly connected to the top of the oil pump device 142, the flexible tube fixedly connected to the rear end of the oil pump device 142 is fixedly connected to the front end of the oil tank member 143, and the flexible tube fixedly connected to the bottom end of the first plug-in frame 1147 is fixedly connected to the oil tank member 143. The above-mentioned connecting structure forms a circulating oil circuit. In the process of lifting and stacking the container 2, the hydraulic cylinder device 144 and the oil pump device 142 are continuously started. Through the above-mentioned circulating oil circuit, the lubricating oil can enter the first plug-in frame 1147 and the second plug-in frame 1148, and be transported to the lower box 1141 to be divided into two oil circuits: An oil circuit passes through the third flexible ring 1142 and enters the hole between the pressure plate 1112 and the combined cover plate 113 to soak the sponge ring 1113. The oiled sponge ring 1113 lubricates the limit rod 133. Then the lubricating oil passes through the first flexible ring 1124 and enters the interior of the upper box body 1121 and enters the subsequent circulating oil circuit.

[0034] Another oil path passes through the lower box body 1141 and enters the column barrel 1145 through the slot opened in the column barrel 1145. The lubricating oil flows upward through the gap between the rotating barrel 1144 and the lower screw member of the combination rod 134, enters the upper box body 1121 through the second flexible ring 1125, and enters the subsequent circulation oil path.

[0035] By manually pulling open the round cover 1162, the filter screen 1163 for intercepting and adsorbing debris can be easily replaced, and the lubricating oil inside the above-mentioned circulating oil circuit can also be supplemented.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
