[0035] In other embodiments, the enclosure 14 may also be eliminated without affecting the use of the equipment.

[0036] In this embodiment, the periphery of the carrying platform 23 has a guard plate extending upward and downward. In other embodiments, the guard plate may be eliminated.

[0037] In order to realize that the driving mechanism 21 drives the scissors-type mechanism 22 to rise and fall, the driving mechanism 21 includes a motor 211, a ball screw 212, a support seat 216, a sliding frame 213, a first linear guide 214 and a bearing seat 215; the motor 211, the first linear guide 214 and the bearing seat 215 are fixed on the base 1, the output end of the motor 211 is connected to one end of the screw of the ball screw 212 through a coupling, the coupling is installed in the support seat 216, the other end of the screw is connected to the bearing seat 215, the nut of the ball screw 212 is connected to the sliding frame 213, the sliding frame 213 is fixed on the first slider of the first linear guide 214, the motor 211 drives the ball screw 212 to rotate, and then the nut of the ball screw 212 drives the sliding frame 213 to move on the first linear guide 214.

[0039] In this embodiment, there are two second linear guides 224 and two third linear guides 225, and the distance between the two second linear guides 224 and the distance between the two third linear guides 225 are determined according to the distance between the two scissors 221. The first linear guide 214 is arranged in the middle of the two second linear guides 224. The state in which the two scissors 211 are not opened is defined as the initial state, and the scissor-type mechanism 22 is driven to be located at the first preset position. When the motor 211 rotates forward, the motor 211 drives the ball screw 212 to rotate and drives the sliding frame 213 to move toward the direction of the motor 211 through the nut of the ball screw 212, so that the end of the first scissor rod 226 connected to the second connecting shaft 223 moves along the second linear guide 224 and the end of the second scissor rod 227 connected to the second connecting shaft 223 moves along the third linear guide 225 toward the motor 211, so that the scissors 21 are opened and the weighing assembly 3 is driven to rise. When the scissors 21 are in the maximum state of opening, the position of the weighing assembly 3 is the second preset position. When the motor 211 rotates in the reverse direction, the nut of the ball screw 212 drives the scissors fork 21 to move away from the motor 211, and the scissors fork 21 returns to the initial state.
