In the implementation, the clamping arm 220 is connected to the fixing seat 210 by bolts and nuts, and the fixing rod 230 is arranged on the fixing seat 210 and one end is clamped in the arc-shaped clamping groove 221, which is used to connect the lifting ring of the sample to be tested. Among them, the frame 110 is welded by multiple rectangular tubes, and is provided with an inspection door, a wiring board, a parameter display panel, a display screen, a detection circuit, etc.; the driving cylinder 140 adopts the mature air cylinder, oil cylinder or electric cylinder in the prior art, etc., and there is no restriction in the description of this implementation, and the driving cylinder 140 can be electrically connected to a conventional PLC controller or a single-chip microcomputer to realize automatic control. Of course, the driving cylinder 140 can also be replaced by other linear mechanisms such as the telescopic motor 310 that can realize the telescopic function.

[0033] In the embodiment of the utility model, when installing the sample to be tested, the lifting ring of the sample to be tested is firstly put on the fixing rod 230, and then the clamping arm 220 is rotated so that its arc-shaped clamping groove 221 is clamped with the fixing rod 230, thereby completing the connection. The operation is simple, convenient and fast, and the efficiency of the detection operation is effectively improved.

[0034] like Figure 3 As shown, in the embodiment of the utility model, the clamping arm 220 is also provided with a mounting hole, in which a spring pin 240 for connecting the fixing rod 230 is installed. The elasticity and spring force of the spring pin 240 further stably connect the fixing rod 230 to the clamping arm 220 to prevent loosening or displacement, thereby ensuring the stability of the connection and the accuracy of the detection.

[0035] like Figure 3 As shown, in the embodiment of the utility model, a connecting sleeve 250 is sleeved on the fixing rod 230, and the lifting ring of the sample to be tested is installed on the connecting sleeve 250. By installing connecting sleeves 250 of different diameters, samples to be tested of different specifications can be adapted to improve practicality.

[0036] like Figure 4-5As shown, in the embodiment of the utility model, a displacement sensor 160 is provided on the frame 110, and a blocking sheet 180 for blocking the light flux is provided on the lifting plate 150. The displacement sensor 160 is used to detect whether the driving cylinder 140 pushes or pulls the lifting plate 150, and then detects the working distance of the sample to be measured on the fixing part. Specifically, a ruler seat 170 is provided on the frame 110, and the displacement sensor 160 is arranged on the ruler seat 170. The scale lines on the ruler seat 170 also facilitate manual observation.

By starting the motor 310, the motor 310 drives the reducer 320 to drive the output shaft 330 to move up and down, thereby driving the slide 120 to move up and down to achieve test adjustment.

[0038] like Figure 1-2 As shown, in the embodiment of the utility model, the frame 110 is provided with a guide column 340, and the slide 120 is sleeved on the guide column 340 and slidably connected thereto, so that the slide 120 is more stable when it is lifted and lowered, wherein the number of the guide columns 340 is preferably two, and the guide column 340 can be connected to the slide 120 through a bushing, and the bushing can ensure that the guide column 340 maintains an accurate position and guidance relative to the slide 120 during movement, and the bushing is made of a low-friction material, which can reduce the friction between the guide column 340 and the slide 120, thereby reducing energy loss and improving efficiency, and can reduce the direct contact between the guide column 340 and the slide 120, thereby reducing wear, extending service life, and reducing maintenance.

[0039] like Figure 1-2 As shown, in the embodiment of the utility model, a guide rod 190 is slidably provided on the frame 110, and one end of the guide rod 190 is connected to the lifting plate 150 to make the lifting plate 150 more stable when lifting and lowering. The number of the guide rods 190 is preferably two. During the test, the driving cylinder 140 lifts the lifting plate 150 and moves it upward on the guide rod 190. Then the lifting plate 150 transmits the pressure to the sample under test through the fixing part, and the pressure is applied to the force sensor 130 through the sample under test. The force sensor 130 then displays the monitored data through the display screen.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
