The power repair device is simple in structure and convenient to operate, saves more labors in circuit collection and release, can realize automatic power supply and power failure, is high in safety, is higher in circuit protecting capacity, prolongs the service life, and can satisfy the power repair illuminating demands.

A self-clinching fixture with improved structure for drill bit is composed of a main body with a lateral shoulder, a rolling ball cover, the bearing and elastomer between said shoulder and cover, jaw holder, jaws installed in said jaw holder, external jacket, self-fastening screw liked to main body via spiral threads, an elastic plate under said shoulder and having several elastic pieces with boss, and a unidirectional ratchet on the lateral lower surface of said shoulder.

The invention discloses an internal contact conical ring type continuously-variable transmission. Two conical wheels are in internal contact with two conical rings respectively, the stress of a contact area is small, and the service life can be improved. Meanwhile, the reliability is high and the power transmission efficiency is high. The continuously-variable transmission comprises a shell, an input shaft, a planetary line, the input conical wheel, the conical rings, the output conical wheel, an output shaft, a differential mechanism, an output gear, a loading mechanism and a speed changing mechanism, wherein the input shaft, the planetary line, the input conical wheel, the conical rings, the output conical wheel, the output shaft, the differential mechanism, the output gear, the loading mechanism and the speed changing mechanism are located in the shell. Power is transmitted between the output conical wheel and the input conical wheel through the conical rings which are arranged outside the two conical wheels in a sleeved mode. The loading mechanism is a hydraulic-mechanical loading mechanism formed by coupling a hydraulic part and a mechanical part. The speed changing mechanism is of a structure similar to a bearing, and speed changing is realized by pushing an outer ring to drive the conical rings.

The present application provides a release device for a pressure vessel, comprising: an accommodation cylinder; a pushing part is provided at one end of the accommodation cylinder, one end of the pushing part is located outside the accommodation cylinder, and the other end is located in a cavity inside the accommodation cylinder; The other end of the housing cylinder is provided with a piercing part, and the piercing part has a through hole that communicates the inner cavity of the housing cylinder with the outside; the container opening of the pressure vessel faces the piercing part; the pushing part is connected to the piercing part through a linkage mechanism , and press the pushing part, the linkage mechanism pushes the piercing part to move in the opposite direction to the pressing direction, so as to pierce the container cover of the pressure vessel, and release the fluid in the pressure vessel to the outside of the accommodating cylinder through the through hole. The pressure vessel release device provided by this application has higher safety and can be operated with one hand when in use. The structural relationship design of the parts in the storage cylinder makes the opening of the pressure vessel less labor-saving and the controllability when releasing the fluid Strong, it can also help to reduce the fluid shock during release, making the bubbles in the discharged fluid smaller and more uniform.
