[0034] The working principle of this utility model:

[0035] When positioning, place the material inside the material frame 2, and then control the motor 441 to drive the screw rod 443 to rotate. The screw rod 443 rotates to drive the connecting piece 433 to move forward on the surface of the support rod 432. When the connecting piece 433 moves, it drives the moving seat 422 to move forward on the surface of the positioning rod 421 in the moving groove 41. When the moving seat 422 moves, it drives the clamping plate 424 to move. When the clamping plate 424 moves to the front side and contacts the material, as the moving seat 422 moves, the clamping plate 424 will be squeezed by the material on the surface of the rotating shaft 423 and rotated counterclockwise to the moving groove 41. The torsion spring 425 is twisted, and when the front of the material is no longer squeezed when the clamping plate 424 is moved, the torsion spring 425 will rotate, and the clamping plate 424 will be rotated clockwise to reset. The front and rear control motors 441 drive the screw rod 443 to rotate in the opposite direction. The screw rod 443 rotates in the opposite direction and drives the connecting member 433 to move backward. The connecting member 433 moves backward and drives the two moving seats 422 to move backward. The moving seat 422 moves to the rear end to drive the two clamping plates 424 to move backward. The clamping plate 424 moves backward and pushes the material backward to cooperate with the rear end surface inside the material frame 2 to clamp the material firmly.

[0036] To sum up: the construction material hoist with a positioning function solves the problem that when using existing construction material hoists, when some materials with shapes that cannot be placed stably are placed in the material frame, they cannot be positioned stably, which easily leads to instability of the materials during lifting, and causes random rolling, deviation and collision.
