[0045] The utility model has the advantage of providing protection above the cylinder by arranging the U-shaped plate 201, the connecting plate 203, the connecting strip 205 and the protective plate 206, so that dropped foreign objects will not directly hit the cylinder, thereby protecting the cylinder, and solving the problem that the cylinder without protection above is easily damaged by the impact of dropped foreign objects.

[0046] Specifically, the protective plate 206 is configured to be an arched structure, with the arched end of the protective plate 206 facing upward; the arched protective plate 206 can unload force when impacted, and can withstand greater impact force.

[0047] Furthermore, the buffer assembly 202 includes a fixed plate 2021, a movable plate 2023 and a buffer spring 2024;

[0048] The fixed plate 2021 is fixed to the inner bottom wall of the U-shaped plate 201; the movable plate 2023 is inserted into the slot 2022 opened at the top of the fixed plate 2021; wherein, the top of the movable plate 2023 is fixedly connected to the bottom side of the connecting plate 203; wherein, a gap is left between the bottom end of the movable plate 2023 and the inner bottom wall of the slot 2022; two buffer springs 2024 are symmetrically arranged between the top side of the fixed plate 2021 and the bottom side of the connecting plate 203; the two ends of the buffer spring 2024 are fixedly connected to the top side of the fixed plate 2021 and the bottom side of the connecting plate 203 respectively, and the elastic coefficient of the buffer spring 2024 is selected and used by the technical personnel in this profession according to actual conditions.

[0049] The utility model has the advantages of buffering and offsetting the force transmitted by the collision, reducing the force borne by the cylinder, and further protecting the cylinder by arranging the fixed plate 2021, the movable plate 2023 and the buffer spring 2024.

[0050] Furthermore, the connecting assembly 204 includes a square frame 2041, a horizontal plate 2043, a plug plate 2042 and an abutting spring sheet 2044;

[0051] The square frame 2041 is fixed on the top side of the connecting plate 203; the horizontal plate 2043 is fixed on the bottom end of the connecting strip 205; the plug-in plate 2042 is fixed on the bottom side of the horizontal plate 2043; wherein the plug-in plate 2042 is plugged and matched with the square frame 2041; the two abutting spring sheets 2044 are respectively arranged on the two inner side walls of the square frame 2041; wherein the two abutting spring sheets 2044 are respectively plugged and matched with the slots 2045 opened on both sides of the plug-in plate 2042.
