The working principle is as follows: when in use, as shown in fig. 1 and fig. 2, a user can install the device to the bottom of the mounting plate 2 through the limiting plate 11, so as to facilitate subsequent rapid positioning and mounting of the transmission mechanism 1 and subsequent rapid lifting of products in suitable regions, and simultaneously, the user can install a suitable clamping claw to the bottom of the mounting bottom plate 42, so as to facilitate subsequent rapid clamping of the products and further effectively improve lifting efficiency,

during the transportation, as shown in fig. 3 and 4, at this time, a user can start the fixed motor 14 through the external control mechanism, the fixed motor 14 can drive the connecting worm 13 to rotate, so that the connecting worm 13 rotates and simultaneously drives the internal thread of the worm casing 33, meanwhile, the two sets of guide shafts 12 can limit the external part of the fixed sleeve 32, so that when the connecting worm 13 rotates, the connecting worm 13 can drive the protection mechanism 3 to displace in the transmission mechanism 1, thereby facilitating the subsequent rapid transportation of products and improving the transportation stability,

as shown in fig. 3, 4, 6 and 7, when the protection mechanism 3 is displaced to the position of the limit plate 11, the connecting worm 13 can continue to drive the worm casing 33 to displace forwards, so that the worm casing 33 can drive the support housing 31 to approach the outside of the limit plate 11, when a collision occurs soon, the connecting baffle 342 at the side of the limit mechanism 34 can contact with the outside of the limit plate 11, because the support housing 31 continues to displace, the limit plate 11 can provide sufficient thrust, so that the connecting baffle 342 can drive the limit mechanism 34 to displace towards the inside of the support housing 31, when the limit mechanism 34 displaces towards the inside of the support housing 31, as shown in fig. 6, the fixing groove 343 inside the limit mechanism 34 can limit the fixed sliding shaft 312 during sliding, so that the fixed sliding shaft 312 can slide inside the fixing groove 343, and because the fixing groove 343 is arranged in a V shape, when the position-limiting mechanism 34 is extruded by the position-limiting plate 11 to move towards the inside of the supporting shell 31, the fixing groove 343 can drive the clamping plate 310 to move towards the bottom through the fixing sliding shaft 312, so as to separate the clamping plate 310 from the inserting groove 313, when the clamping plate 310 is separated from the inserting groove 313, the worm casing 33 loses the position limitation of the clamping plate 310, and can rotate along with the rotation of the connecting worm 13, so that the protection mechanism 3 loses the power of moving towards the front, so that the protection mechanism 3 can keep stable outside the position-limiting plate 11, meanwhile, when the fixing motor 14 reverses, the supporting force of the position-limiting mechanism 34 by the position-limiting plate 11 is reduced, the elastic force of the spring shaft 311 can drive the position-limiting mechanism 34 to reset through the fixing sliding shaft 312, and meanwhile, the clamping plate 310 can be inserted into the inside of the inserting groove 313 through the action of the clamping plate 310, at this time, because of the position, when the connecting worm 13 rotates reversely, the connecting worm 13 can drive the protection mechanism 3 to perform the return movement through the worm casing 33, thereby facilitating the subsequent re-hoisting, improving the efficiency of hoisting the product,

when clamping and lifting a product, as shown in fig. 2 and 4, a user can start the installation motor 314 through the external control mechanism, at this time, the installation motor 314 can drive the threaded rod 38 to rotate, the threaded rod 38 can drive the threaded plate 39 to displace towards the lower part when rotating, when two groups of threaded plates 39 simultaneously displace towards the lower part, the threaded plate 39 can drive the clamping mechanism 4 to displace towards the lower part through the connecting plate 37, so as to conveniently position the product, when clamping, as shown in fig. 9, the connection motor 43 can drive the fixed gear disk 44 to rotate, when the fixed gear disk 44 rotates, the fixed gear disk 44 can simultaneously drive the four groups of transmission gears 47 to mesh and rotate through the internal gear groove 46, so that the transmission gears 47 can drive the connection screw rod 49 to rotate, when the connection screw rod 49 rotates, the four groups of guide sliders 48 can be simultaneously driven to move centripetally or separately inside the connection sliding groove 45, therefore, the quick and stable clamping operation of products with different sizes and models is convenient to follow, and the subsequent lifting is convenient.
