[0025] The bottom plate 2 is provided with four positioning holes 12 in a rectangular array on the upper surface, and a positioning rod 1 penetrates through the four positioning holes 12;

[0026] The connecting block 13 is provided with a threaded hole 14 on the upper surface, and the installation plate 4 is provided with a circular hole 17 on each side and a circular hole 17 on the lower surface. The transmission shaft of the motor 5 extends into the circular hole 17, and the transmission shaft of the motor 5 is fixed with a threaded rod 15 which penetrates through the threaded hole 14 and is threadedly connected;

[0031] Example two:

[0032] The bracket 11 is provided with a circular hole 29 on the upper surface, and the hydraulic rod 9 installed on the hydraulic cylinder 10 penetrates through the circular hole 29;

[0033] The hydraulic cylinder 10 and the hydraulic rod 9 realize the conversion and transmission of hydraulic energy through precise cooperation in the hydraulic system, thereby driving the movement of various mechanical equipment. The hydraulic cylinder 10 is a sealed container filled with hydraulic oil, which is usually composed of a cylinder barrel, a cylinder cover, a piston, and a piston rod. The piston divides the hydraulic cylinder 10 into two chambers, and the piston rod connects the piston and the external load. The hydraulic rod 9 usually refers to the end of the piston rod connected to the piston, and the other end extends out of the hydraulic cylinder 10 and is connected to the external mechanism.

[0035] The working principle of the motor two 8 is based on electromagnetic induction and Lorentz force (or Ampere force). Simply put, the motor two 8 generates force in a magnetic field through electric current, thereby driving mechanical movement. This process can be divided into two key parts: electric energy input and mechanical energy output.

[0036] The core components of the motor two 8 include a stator (fixed part) and a rotor (rotating part). The stator is usually composed of coils, which generate a magnetic field after being electrified. The rotor is located in the magnetic field, and when the current passes through the rotor coil, according to the Lorentz force principle (or Ampere force principle), the magnetic field will exert a force on the current, thereby pushing the rotor to rotate.

[0037] The outer wall of the rotating disc 23 is sleeved with a rubber sleeve two 22, and the bottom end of the rubber sleeve two 22 is attached to the top end of the glass disc 6.
