Telescopic recorder convenient to check on site

Abstract

The invention discloses a telescopic recorder convenient to check on site. The telescopic recorder convenient to check on site comprises a fixed column; a support column is welded on one side of the fixed column; a connecting rod groove is formed in one side of the support column; a connecting rod is slidingly mounted in the connecting rod groove; one end of the connecting rod extends outside theconnecting rod groove; a recorder body is fixedly mounted at the end, positioned outside the connecting rod groove, of the connecting rod; a first rotating shaft groove is formed in the end, positioned in the connecting rod groove, of the connecting rod; a first rotating shaft is rotationally mounted in the first rotating shaft groove; one end of the first rotating shaft extends outside the firstrotating shaft groove; a second rotating shaft groove is formed in the inner wall of the side, far from the connecting rod, of the connecting rod groove; and the second rotating shaft groove is rotationally connected with the first rotating shaft. The telescopic recorder convenient to check on site is simple in structure and convenient to use; a recorder body can be telescopically adjusted to achieve higher automation degree, easy operation and time saving; and people is more convenient to use the recorder body.

Problems solved by technology

[0003] A new patent for a portable recorder with patent application number 201621219438.X discloses a portable recorder, including a recorder body, a main control chip, a power supply and a data memory are arranged in the recorder body, and the main control chip is connected to the power supply and the data memory respectively. The data memory is connected, and a camera is installed in the upper middle of the front of the recorder body and the camera is connected to the input terminal of the main control chip. A law enforcement mark is set in the center of the front of the recorder body, and a groove is set directly below the law enforcement mark. For the name tag of the personnel, chutes are set on the upper and lower sides of the groove, and the L-shaped insulating expansion board is stuck in the chute to move back and forth to cover or reveal the name tag. The L-shaped insulating telescopic plate is provided with an electric contact two and the electric contact two corresponds to the position of the electric contact one. The electric contact one, the electric contact two and the L-shaped insulating telescopic plate form a control switch and are arranged on the main control chip. and the connecting line between the power supply, however, the existing recorder cannot be retracted, and it is very inconvenient to use during on-site inspection, which is not conducive to people's use. With the advancement of science and technology and the development of society, people Higher requirements are put forward for the recorder, so we propose a telescopic recorder for on-site inspection to solve the above problems
