[0025] The working principle of the device without cleaning the glass slag on the test bench is as follows: first, the instrument to be tested is placed on the support seat 703, and then the forward and reverse motor 610 is controlled by the controller to run, and the forward and reverse motor 610 drives the worm 608 to rotate. Under the condition that the turbine 607 and the worm 608 are meshed and connected with each other, the rotation of the worm 608 can drive the adjustment disk 602 to rotate through the turbine 607 and the hollow shaft 606, and the rotation of the adjustment disk 602 can drive the L-shaped support rod 603 to translate in the limit base 601 through the limit pin 604, and several groups of L-shaped support rods 603 translate and drive several groups of clamping plates 804 in the clamping assembly 8 to press against the arc edge of the instrument; The cylinder drives the pressure detection module 3 to move downward to detect the instrument. During the downward movement of the pressure detection module 3, the protective cover 504 in the protective component 5 will first contact the upper end surface of the limit base 601. The avoidance groove on the protective cover 504 avoids the first limit rod 801 in the clamping component 8. During the continuous downward movement of the pressure detection module 3 and the first connecting rod 4, the ball 502 in the protective component 5 rolls in the limit slide groove 503 on the first connecting rod 4. When the glass dial of the instrument is cracked during the pressure detection module 3 to perform fracturing detection on the instrument, the protective cover 504 protects the inspector to prevent the broken glass from collapsing outside the detection platform, thereby improving the safety factor of the inspector.

[0026] The broken glass will fall into the conical bucket 701. Since the inner wall of the conical bucket 701 is smooth and inclined, the glass slag will directly pass through the conical bucket 701 and the first conduit 704 and fall into the second conduit 705, which can effectively prevent glass slag from falling on the surface of the detection table. There is no need to clean the detection table surface, thereby effectively improving the detection efficiency of the instrument.

[0027] Embodiment 2 See also Figure 6 , this embodiment further explains Example 1, the connecting component 9 includes a first annular plate 901 fixedly sleeved on the outer side of the first conduit 704, and the first annular plate 901 is located at the lower side of the turbine 607, the outer side of the second conduit 705 is fixedly sleeved with a second annular plate 902, the outer side of the second conduit 705 is located between the first annular plate 901 and the second annular plate 902 and is movably sleeved with a third spring 903, and the two ends of the third spring 903 are respectively fixedly connected to the first annular plate 901 and the second annular plate 902, a plurality of groups of circumferentially equidistantly distributed push rods 904 are fixedly installed at the lower end of the turbine 607, and a hemispherical portion is provided at the lower end of the push rod 904, and the connection mode between the push rod 904 and the second conduit 705 is a movable abutment.

[0028] In this embodiment: when the driving mechanism 6 drives the clamping assembly 8 to clamp or release the instrument, the turbine 607 in the driving mechanism 6 drives the plurality of groups of push rods 904 to rotate together. The rotation of the plurality of push rods 904 exerts an intermittent squeezing force on the second conduit 705. The second conduit 705 is squeezed by the push rods 904 and tilts and vibrates toward its discharge end. During this period, the third spring 903 drives the second conduit 705 to rebound and reset, so that the second conduit 705 can perform the above-mentioned action under the action of the push rods 904 and the third spring 903, thereby facilitating the second conduit 705 to shake the glass slag inside it to the port at the discharge end, thereby facilitating the discharge of the glass slag inside the second conduit 705.

[0029] Embodiment 3 See also Figure 4This embodiment further illustrates other embodiments that the cross-sectional shape of the second connecting rod 702 is an isosceles triangle.

[0030] In this embodiment, the second connecting rod 702 has an isosceles triangle cross-section, so that the second connecting rod 702 has a strong anti-bending performance and can effectively prevent glass slag from remaining on the second connecting rod 702.
