[0033] To summarize, by placing the object on the top of the bottom plate 530 and rotating the turntable 551, the bidirectional threaded rod 550 is driven to rotate, so that the slider 560 drives the clamping plate 570 to approach each other, thereby clamping and fixing the object, and then the steel cable 460 is contracted to drive the top plate 510 to rise. During the rising process, the pressure plate 580 descends on the outside of the slide rod 520, thereby pressing the object and further fixing it to prevent the object from shaking and falling off during the rising process, thereby ensuring the stability of the lifting, ensuring the safety of the lifting, and reducing installation risks.

[0034] Please refer again Figure 1The output shaft end of the servo motor 450 is fixedly connected to the front end of the transmission shaft of the winding disk 440 , and the input end of the servo motor 450 is electrically connected to the output end of the external power supply, and the steel cable 460 is located outside the pulley 410 .

[0036] Please refer again Figure 4 A buffer mechanism 600 is fixedly connected to the bottom of the bottom plate 530, and the buffer mechanism 600 includes an installation cavity 610, a damper 620, a buffer plate 630, a first installation seat 640, a rotating plate 650, a mounting groove 660, a limiting rod 670, a second installation seat 680 and a buffer spring 690. An installation cavity 610 is opened at the bottom of the bottom plate 530, and the dampers 620 are fixedly connected at the four corners of the top of the installation cavity 610. The buffer plate 630 is fixedly connected to the bottom end of the damper 620. The first installation seat 640 is fixedly connected to the middle of the top of the installation cavity 610. The left and right parts of the inner front and rear parts of the first installation seat 640 are rotatably connected to the rotating plate 650. A mounting groove 660 is opened in the middle of the top of the buffer plate 630. The middle part of the front and rear parts of the left and right sides of the installation groove 660 is fixedly connected to the limiting rod 670. The second installation seat 680 is symmetrically slidably connected to the outer side of the limiting rod 670, and the buffer spring 690 is sleeved on the middle part of the outer side of the limiting rod 670.

[0037] Please refer again Figure 4 The buffer plate 630 is slidably connected to the interior of the installation cavity 610 , and the outer wall of the buffer plate 630 is in contact with the inner wall of the installation cavity 610 .

Through the deformation of the buffer spring 690, the impact of falling to the ground is buffered, thereby ensuring the stability of the landing of the object, avoiding damage to the object, and improving the practicality of the device.

[0040] In specific use, the technical personnel in this field install the device at a designated location. When lifting is required, the object is placed in the middle of the top of the bottom plate 530, and the turntable 551 is rotated to drive the bidirectional threaded rod 550 to rotate, so that the slider 560 drives the clamping plate 570 to approach each other to clamp and fix the object. Then, the servo motor 450 is lifted to rotate the winding disk 440 to shrink the steel cable 460 and drive the top plate 510 to rise. During the rising process, the pressing plate 580 descends on the outside of the sliding rod 520 to press the object. After the object is transported to the designated location, the placement mechanism 500 is lowered. First, make the vertical plate 590 contact the ground, and gradually make the vertical plate 590 drive the pressure plate 580 to rise on the outside of the slide bar 520 during the heavy descent. When the buffer plate 630 contacts the ground, the buffer plate 630 rises inside the installation cavity 610, so that the first installation seat 640 squeezes the rotating plate 650, causing the rotating plate 650 to deflect, thereby making the second installation seat 680 move away from each other, stretching the buffer spring 690, and cushioning the impact of falling to the ground through the deformation of the buffer spring 690. After completely landing, reverse the turntable 551 to make the clamps 570 move away from each other, thereby releasing the fixation of the object.
