[0002] Pressure instruments are generally used to measure the pressure of gas or liquid. They are industrial automation instruments that measure and indicate pressures higher than the ambient pressure. They are also called pressure gauges or pressure gauges. They are found in almost all industrial processes and scientific research fields, such as thermal pipelines, oil and gas transmission, water and gas supply systems, and vehicle repair and maintenance shops. Especially in industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used because of their elastic sensitive elements with high mechanical strength and easy production.

[0003] In the prior art, such as Chinese patent CN219608999U, a clamping device for installing a pressure instrument includes a mounting seat, a through hole is opened on the top of the mounting seat, a bidirectional screw is connected to the bottom of the inner cavity of the mounting seat through a bearing, a driving member is arranged at the bottom of the right side of the mounting seat, the driving member is connected to the right end of the bidirectional screw, both ends of the outer wall of the bidirectional screw are threadedly connected with a nut, a mounting plate is installed on the top of the two groups of nuts, and a clamping block is installed on the side of the two groups of mounting plates close to the center of the mounting seat. The present application can fix and clamp the connecting rod through two groups of clamping blocks through the coordinated arrangement of the mounting seat, the through hole, the bidirectional screw, the driving member, the nut, the mounting plate and the clamping block, thereby improving the stability of the pressure instrument, reducing the shaking of the pressure instrument when it is fixed and used, thereby reducing the loss caused to the pressure instrument, and helping to extend the service life of the pressure instrument.

[0004] In the above patent, the two mounting plates are driven by a motor to move toward each other, so as to clamp and fix the connecting rod of the instrument body, and by pulling the two movable rods, the two clamping seats are moved in opposite directions. Under the elastic reset action of multiple springs, instrument bodies of different specifications can be clamped and fixed, and a good clamping and fixing effect is achieved. However, when fixing and clamping the instrument body, both hands are required to pull the two movable rods at the same time, so that the two clamping seats move in opposite directions and generate a gap into which the instrument body can be placed. Due to the elastic reset action of the spring, personnel are required to continuously pull the movable rod to ensure the size of the gap, and inserting the instrument body requires the assistance of others, which is not convenient for a single person to quickly fix the pressure instrument.
