The surface of the resist plate 4 is fixedly connected with a fixing block 5. The surface of the resist plate 4 is movably connected with a resist wheel 6. The surface of the fixing block 5 is fixedly connected with a tension spring 7. The surface of the adjusting frame 2 is fixedly connected with a supporting block 8. An adjusting groove 9 is provided on the inner side of the adjusting groove 9. A supporting spring 10 is fixedly connected to the inner side of the adjusting groove 9. An action block 11 is fixedly connected to the surface of the supporting spring 10. A rotating wheel 12 is movably connected to the inner side of the action block 11. A limiting block 13 is fixedly connected to the outer surface of the action block 11. Through the sliding connection between the main frame 1 and the adjusting frame 2, under the action of the display screen 3, the display effect of the measured data is achieved. Under the action of the resist plate 4 and the rotating wheel 12, the sliding adjustment effect between the main frame 1 and the adjusting frame 2 is improved. The display screen 3 is an existing product and is not used as a technical protection point of the present application. No excessive statements are made here.

[0024] Furthermore, the cross-section of the adjusting frame 2 is in a "U" shape, and the abutment plates 4 are in two groups acting on the surface of the adjusting frame 2. The outer surface of the abutment plates 4 is in an arc shape. Through the connection between the adjusting frame 2 and the abutment plates 4, under the action of the abutment plates 4, the adjusting frame 2 and the main frame 1 are in close contact, thereby improving the adjustment sliding effect of the adjusting frame 2 on the main frame 1.

[0025] Furthermore, the resist plate 4 acts on both sides of the main frame 1 through the adjusting frame 2, and the resist wheel 6 is cylindrical in shape. The resist wheel 6 is connected to the main frame 1 through the resist plate 4. Through the rotational connection between the resist plate 4 and the resist wheel 6, under the action of the resist wheel 6, the resist plate 4 and the main frame 1 are in rolling contact, thereby improving the contact effect between the adjusting frame 2 and the main frame 1.

[0026] Furthermore, the fixed block 5 is in a plate shape and acts on a side of the back plate 4 close to the main frame 1, and the support block 8 acts on the bottom of the fixed block 5 through the adjustment frame 2. Through the connection between the fixed block 5 and the back plate 4, and the connection between the support block 8 and the tension spring 7, the back wheel 6 and the main frame 1 are tightly fitted, thereby improving the adjustment effect of the adjustment frame 2 and the main frame 1.

[0027] Furthermore, the push plate 4 is elastically connected to the adjustment frame 2 through the tension spring 7, and the adjustment grooves 9 are evenly distributed on the inner side of the adjustment frame 2 in the shape of square grooves. Through the connection between the tension spring 7 and the fixed block 5, under the action of the tension spring 7, the elastic control effect of the push plate 4 on the adjustment frame 2 is achieved.

[0028] Furthermore, both ends of the support spring 10 are fixedly connected to the inner side of the adjusting groove 9 and the surface of the action block 11.

The limit blocks 13 are distributed in two opposite groups on both sides of the action block 11. The sliding groove and the limit block 13 in the adjusting groove 9 are slidably connected. Under the rotational connection between the action block 11 and the rotating wheel 12, the connection between the limit block 13 and the action block 11 realizes the effect of limiting the sliding angle of the action block 11 in the adjusting groove 9.

[0030] Working principle: When the adjusting frame 2 is adjusted, through the connection between the adjusting frame 2 and the adjusting groove 9, the connection between the adjusting groove 9 and the supporting spring 10, and the connection between the supporting spring 10 and the acting block 11, the acting block 11 is elastically slid in the adjusting groove 9, and the rotating connection between the rotating wheel 12 and the acting block 11 makes the adjusting frame 2 and the main frame 1 rolling contact, thereby improving the adjustment performance between the adjusting frame 2 and the main frame 1, and through the connection between the abutment plate 4 and the fixed block 5, through the connection between the fixed block 5 and the tension spring 7, and the connection between the tension spring 7 and the supporting block 8, the abutment wheel 6 and the main frame 1 are tightly abutted, thereby improving the stability of the sliding of the adjusting frame 2 on the main frame 1.
