[0025] A sliding groove 311 is formed in the middle of the upper end of the base plate 31 along the left-right direction; the jacking mechanism comprises a jacking shaft 33, a jacking seat 34, a jacking rod 35 and a plurality of bearing seats, the jacking shaft 33 is arranged on the upper side of the base plate 31 through the bearing seats, and the shaft of the jacking shaft 33 is parallel to the forming direction of the sliding groove 311; the jacking seat 34 is sleeved on the jacking shaft 33 and is threadedly connected with the jacking shaft 33, and the jacking seat 34 is slidingly arranged in the sliding groove 311, and the jacking shaft 33 can drive the jacking seat 34 to reciprocatingly displace along the sliding groove 311 by being rotated; the upper end of the jacking rod 35 is rotationally connected with the lower end of the face plate 32, and the lower end of the jacking rod 35 is rotationally connected with the jacking seat 34, and it can be understood that the jacking rod 35 and the main plane of the base plate 31 and the main plane of the face plate 32 all form an included angle, when the jacking shaft 33 is rotated to drive the jacking seat 34 to reciprocatingly displace along the sliding groove 311, the included angle between the jacking rod 35 and the base plate 31 can be changed, so that the included angle between the main plane of the base plate 31 and the main plane of the face plate 32 can be changed, thereby realizing the orientation of the positioning clamp 4 installed on the face plate 32.

[0026] In one embodiment, a plurality of through holes for positioning are longitudinally opened on the panel 32. The multi-hole design allows for more options for the installation position of the positioning fixture, and allows for flexible adjustment of the installation position of the positioning fixture, thereby improving versatility and adaptability.

[0027] The positioning fixture 4 includes a fixing base 41, three clamping plates 42, a protective sponge 43, a plurality of high-elastic straps 44 and a plurality of hook screws 45. The fixing base 41 is fixedly mounted on the upper end of the panel 32 by being surrounded by the three clamping plates 42. During implementation, a groove is formed on the outer periphery of the fixing base 41, and a protrusion is provided on the clamping plate 42 corresponding to the position of the groove. The protrusion is at least partially located in the groove. The protrusion is pressed against the fixing base 41 to stabilize the fixing base 41. The clamping plates 42 are connected to the panel 32 by bolts.

[0029] Working principle of this lifting platform device:

[0030] Rotate the lifting shaft 33 to adjust the panel 32 to the appropriate angle, and manually crank the lifting platform 2 to move the positioning fixture 4 to the appropriate height as a whole. Place the workpiece that needs to be worked on the operating table in the protective sponge 43, and use the high-elastic strap 44 and the hook screw 45 to fix the workpiece. After checking the fixation, operate the mobile platform 1 to drive the lifting platform 2, the multi-angle adjustment platform 3 and the positioning fixture 4 to the operating area. The operator uses the foot-operated brake pad to fix the lifting platform device, and operates the foldable handwheel to adjust the operating height and angle. After completing the work, loosen the foot-operated brake pad, transport the workpiece to the designated position, adjust the height, loosen the high-elastic strap, and unload the workpiece.

[0031] The multi-hole design of the adjustable angle platform's panel allows for more options for positioning the positioning fixture. Flexible adjustment of the positioning fixture's installation position enhances versatility and adaptability, avoids device monotony, and significantly improves compatibility. The integrated positioning plate and protective sponge enhance overall rigidity and prevent deformation of the protective sponge, which could cause product slippage or displacement, effectively increasing safety and stability. To ensure the product and protective sponge form an integral whole, hook screws are added to the upper side of the positioning plate. When the product is placed on the protective sponge, an adjustable, highly elastic strap is installed for added stability.

[0032] By combining the lifting platform with the multi-angle adjustment platform, different height and angle adjustments can be achieved to meet the needs of different scenarios. By using opposing support rods and adding angle codes at the surrounding connection points, the lifting platform device is always stable and does not shake during the process of placing and taking products.
