It has a wide range of applications, such as measuring diameter, width, thickness, slit, position, concentricity, height, length, and side length. When in use, it is generally measured using a photoelectric measuring instrument.

[0003] After searching the publication (announcement) number: CN217900754U, a photoelectric measuring instrument that is convenient for hanging and placement is disclosed, which solves the problem that the photoelectric measuring instrument in the prior art does not have the hanging function and cannot be hung in a certain place for measurement during measurement. It still needs to be manually held for measurement, which is very inconvenient. A photoelectric measuring instrument that is convenient for hanging and placement includes a photoelectric measuring instrument body, the photoelectric measuring instrument body is provided with a notch, a U-shaped plate is fixedly connected to the notch, and a pushing component and a hanging component that are convenient for hanging are provided in the U-shaped plate. The utility model enables the photoelectric measuring instrument body to have a hanging function, so that the photoelectric measuring instrument body can be hung, making detection more convenient.

[0004] Although the above scheme enables the photoelectric measuring instrument body to have a suspension function, which facilitates the suspension of the photoelectric measuring instrument body, the suspension method is relatively loose and prone to shaking, resulting in certain errors in the measurement data sometimes. Therefore, we propose a photoelectric measuring instrument that is easy to hang and place. Utility Model Content

[0005] The main purpose of the utility model is to provide a photoelectric measuring instrument that is convenient for hanging and placing. By setting a first clamping unit and a second clamping unit, the problem that the hanging method is relatively loose and easy to shake, resulting in certain errors in the measured data sometimes, is solved.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] The second clamping unit includes a fixed clamping plate installed on the side wall of the main unit and located below the U-shaped box, a fixed column installed at the bottom of the fixed clamping plate, a movable clamping plate movably installed on the side surface of the fixed column, and a limit block installed at the bottom end of the fixed column.

[0010] Preferably, the main unit comprises a measuring instrument body, a measuring head and a control button mounted on the surface of the measuring instrument body, and the measuring head is located above the control button.

[0011] Preferably, the main unit further comprises a display screen mounted on the surface of the measuring instrument body.

[0012] Preferably, arc-shaped grooves are formed on two opposite side walls of the measuring instrument body.

[0013] Preferably, the clamping member comprises a moving member mounted on the screw rod, and an L-shaped clamping plate mounted on the top of the moving member, and the clamping member has two groups, and the two groups of clamping members are symmetrically arranged with respect to a bisecting plane of the screw rod.

[0014] Preferably, the first clamping unit further comprises a limiting washer installed on the inner side wall of the U-shaped box, and the limiting washer is sleeved on the peripheral side surface of the screw rod.

[0015] Preferably, the adjusting unit comprises a connecting spring having one end fixedly connected to the fixed clamping plate and the other end fixedly connected to the movable clamping plate, and a stretching handle installed at the bottom of the movable clamping plate.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the utility model, by setting the first clamping unit and the second clamping unit, when it is necessary to hang the measuring instrument on the horizontal hanging object, the measuring instrument body is brought close to the horizontal hanging object so that the two L-shaped clamping plates are arranged on both sides of the horizontal hanging object, and the driving motor is started to rotate the driving motor drive screw. Since the screw rod is provided with threads with opposite rotation directions at both ends, the two moving parts can drive the L-shaped clamping plates to move in the direction of approaching each other until the inner side wall of the L-shaped clamping plate fits the horizontal hanging object and stops, so that the measuring instrument is stably hung on the horizontal hanging object; when it is necessary When hanging the measuring instrument on a longitudinally suspended object, first, pull down the stretching handle to move the movable clamping plate along the fixed column and stretch the connecting spring. Subsequently, fit the bottom wall of the fixed clamping plate with the top of the longitudinally suspended object. At this time, remove the tension applied to the stretching handle. Under the elastic force of the connecting spring, the movable clamping plate automatically moves upward until it fits with the bottom of the longitudinally suspended object and stops. The measuring instrument is stably suspended on the longitudinally suspended object, thereby achieving a stable suspension of the photoelectric measuring instrument body, avoiding shaking, and improving the accuracy of the measurement data.
