[0002] A lift is a vertical transportation device used to transport people and objects vertically from one floor or ground to another. It usually consists of an electric drive system and a movable lifting platform.

[0003] After searching, the patent number (CN201923734U) is a device for preventing top impact for elevators, which relates to an elevator. It is provided with a fixed bracket, a guide screw, a spring, a bearing kit and a travel switch. The fixed bracket is fixedly connected to the uppermost end of the elevator transmission frame with bolts, the guide screw and the travel switch are fixed on the fixed bracket, the spring is sleeved on the screw, the bearing kit is installed at the end of the guide screw and can slide along the axial direction of the guide screw, the bearing in the bearing kit is in close contact with the back of the rack on the elevator guide rail frame and presses the spring, and the bearing kit presses the limit switch contact to ensure that the circuit of the drive motor is in the on state. When in use, when the construction elevator has a top impact, the bearing first rushes out of the rack, and the spring pushes the bearing kit outward, triggering the travel switch, so that the drive motor is powered off, and the elevator stops running to avoid top impact. In actual use, it is easy to disassemble and assemble, and it is effective and reliable. However, when this structure is used, it is not convenient to adjust the use length, which makes it very limited to use, so now a new structure is proposed to solve this technical problem.
