The invention provides an embolism spring coil system which comprises a conveying device and a spring coil, the conveying device comprises a conveying pipe and a guide wire arranged in the conveying pipe, the conveying pipe is provided with a cavity, the cavity comprises a first cavity body and a second cavity body located at the far end of the first cavity body, and the second cavity body is provided with a partition part to divide the second cavity body into a first channel and a second channel; the spring ring device comprises a spring ring and an anti-unwinding wire arranged in the spring ring, the far end of the anti-unwinding wire is fixedly connected with the far end of the spring ring, a rope sleeve is arranged at the near end of the anti-unwinding wire, the rope sleeve penetrates through the first channel and extends into the first cavity, and the guide wire sequentially penetrates through the rope sleeve and the second channel. The rope sleeve of the anti-unwinding wire penetrates through the first channel and is arranged on the guide wire in a sleeving mode, so that stable connection of the conveying device and the spring ring device is achieved, the locking state can be kept even if the conveying device passes through a bent blood vessel, the situation of mistaken unwinding is avoided, the surgical risk and the operation difficulty are reduced, and the working efficiency is improved. And meanwhile, the spring ring can be reliably released through the arrangement of the anti-unwinding wire.

A contact system includes a contact support and a moving contact. The moving contact has moving contacts at both ends that mate with stationary contacts. The contact support has two raised mounting protrusions on the side away from the stationary contacts, and a clearance notch between the two mounting protrusions. Each of the two mounting protrusions of the contact support has at least one contact spring, and the contact springs on the two mounting protrusions are respectively connected to the two ends of the moving contact where the moving contacts are located. A changeover switch includes a housing and a contact system. The housing contains a load terminal, a power supply I terminal, and a power supply II terminal. The load terminal is electrically connected to the moving contact. Two stationary contacts are respectively located on the power supply I terminal and the power supply II terminal. In this invention, the contact support has a notch design on the side near the load terminal, and two mounting protrusions are spaced apart for mounting contact springs, saving space and increasing the rotation angle of the contact support.

The invention belongs to the technical field of curtain wall grinding, and specifically discloses a glass curtain wall side grinding device, comprising a base, a working area is fixedly connected to the top of the base, vacuum suction cups are evenly distributed inside the working area, a moving frame is arranged on the top of the base, a mounting head is arranged on the surface of the moving frame, an electric push rod is arranged inside the mounting head, and a mounting block is fixedly connected to the output end of the electric push rod; by arranging a grinding structure, the clamping effect on the glass curtain wall can be enhanced during the grinding process, and the buffer block can be arranged around the grinding to reduce the influence of vibration, thereby reducing the situation that the fixed glass curtain wall is damaged by the influence of vibration during the grinding process, and at the same time, in the process of vibration generated by grinding the glass curtain wall, part of the force can be used to overcome the reaction force of the first spring after being squeezed, thereby further weakening the influence on the glass curtain wall.

The invention discloses a steel pipe cutting device and method for building decoration, and relates to the technical field of steel pipe cutting. The steel pipe cutting device comprises a base, a shell is fixedly mounted at the top of the base, supporting legs are fixedly mounted at the bottom of the base, a discharging opening is formed in the surface of the shell, and a cutting groove is formed in the surface of the base; the L-shaped plate is slidably mounted on the inner wall of the shell, a driving device is arranged in the L-shaped plate, a square groove is formed in the surface of the L-shaped plate, the fixed seat is fixedly mounted at the top of the L-shaped plate, the fixed arc plate is rotatably mounted at the top of the fixed seat, and the two arc rods are fixedly mounted at the two ends of the fixed arc plate. A triangular block is fixedly installed on the surface of an arc-shaped rod, a steel pipe can be fixed through a fixing arc plate, the situation that the position of the steel pipe deviates when the steel pipe is cut, and a cutting tool possibly bears irregular counter-acting force is prevented, and the precision during cutting is improved.
