[0004] But the above structure has the following defects: first, the lifting mechanism on both sides is controlled separately, which needs two separate motors, increasing the production cost; second, the two motors work separately, which is easy to cause the lifting of the antiskid pads on both sides to be different, resulting in poor stability. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a multifunctional stainless steel caster to solve the problems in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical scheme: a multifunctional stainless steel caster, including the roller 1 arranged at the bottom of the roller frame 4, the rotating table 5 above the roller frame 4 and the antiskid pads 2 arranged on both sides, characterized in that: the rotating table 5 is provided with the box body 6 above, the guide rods 3 that can slide up and down are arranged on both sides in the box body 6, the antiskid pads 2 are arranged below the guide rods 3, the guide rods 3 are connected through the connecting frame 12 and driven to move up and down by the motor 8 on the cover 7.

[0007] Further, the box body 6 is provided with the mounting groove 11 in the center, the limiting grooves 10 and the guide sleeves 9 that are symmetrical are arranged on both sides of the mounting groove 11, and the guide rods 3 are coaxial with the guide sleeves 9 and slide in the guide sleeves 9.

[0008] Further, the width of the connecting frame 12 is equal to the width of the limiting groove 10.

[0009] Further, the center of the connecting frame 12 is provided with a threaded hole 13.

[0010] Further, the front end of the motor 8 is provided with a lead screw 14 matched with the threaded hole 13.

[0011] Further, the length of the lead screw 14 is the same as the depth of the mounting groove 11.

[0012] The utility model has the advantages of: first, the lifting mechanism on both sides is controlled by a separate motor, which reduces the production cost; second, the motor controls the anti-skid pads on both sides to lift simultaneously, avoiding instability. BRIEF DESCRIPTION OF DRAWINGS
