[0023] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-3 As shown, a test machine includes a base 1, on which a carrier 2 for placing an object to be tested and a probe 3 for detecting the object to be tested are provided, the carrier 2 is detachably connected to the base 1, and the base 1 is provided with a plurality of probe 3 holes for fixing the probe 3. The carrier 2 is used for positioning the object to be tested. Since there are many types of objects to be tested and the shapes of the carrier 2 are different, the shapes of the carrier 2 are also many. In order to reduce the cost of the equipment, the present technology is designed so that the carrier 2 can be detachably mounted on the base 1, so that the carrier 2 can be replaced to meet the positioning requirements of different objects to be tested. The base 1 is provided with a plurality of detachable connecting columns 4, and the top of the connecting column 4 is threadedly connected to the object to be tested to meet the installation requirements of different carriers 2. At the same time, according to the detection requirements of different objects to be tested, the probe 3 can be inserted from the bottom into the probe 3 hole at the corresponding position, so as to realize the detection requirements of different types of objects to be tested. In this embodiment, the base 1 is an openable box structure, which can accommodate the acquisition system of the probe 3 signal or the maintenance tools of the test machine, the carrier 2, etc., and can prevent debris from entering the system.

[0025] A toggle clamp 5 for manual downward pressing is provided above the carrier 2, a supporting cross plate 6 is provided at the downward pressing end of the toggle clamp 5, a pressing rod 7 for pressing down the object to be tested is provided at the bottom of the supporting cross plate 6, a plurality of mounting holes for mounting the pressing rod 7 are provided on the supporting cross plate 6, the number and mounting positions of the pressing rods 7 are determined according to the shape of the object to be tested, and generally there are 3-4 pressing rods 7, and the carrier 2 is pressed down through 3-4 downward pressing points, and the downward pressure is relatively uniform, so that the object to be tested can contact the probe 3.

[0026] The toggle clamp 5 includes an toggle clamp seat 8 for fixing the toggle clamp 5, and a first connecting end 9 and a second connecting end 10 are provided on the working side of the toggle clamp seat 8, wherein the first connecting end 9 is located directly above the second connecting end 10; the first connecting end 9 is rotatably connected to a pull rod 11, so that the pull rod 11 can be longitudinally rotated by -90° to +90°; the second connecting end 10 is provided with a pressure rod 12 that can move up and down, and the second connecting end 10 limits the lateral freedom of the pressure rod 12, so that the pressure rod 12 can only move up and down. In this embodiment, the second connecting end 10 is an annular structure, and the pressure rod 12 vertically penetrates the second connecting end 10. A connecting rod 13 is rotationally connected between the rotating end of the pull rod 11 and the gripping end, and the other end of the connecting rod 13 is rotationally connected to the pressure rod 12. When the pull rod 11 rotates along the rotating end, the connecting rod 13 is driven to move upward, and the lower end of the connecting rod 13 pulls the pressure rod 12 upward; conversely, when the pull rod 11 rotates along the rotating end, the connecting rod 13 is driven to move downward, and the lower end of the connecting rod 13 pushes the pressure rod 12 downward.

[0027] The middle part of the connecting rod 13 is provided with a bent portion 14 bent outward. When the pull rod 11 is pulled up, the bent portion 14 will bypass the first connecting end 9, which can ensure the rotation angle of the pull rod 11 and avoid the problem of the connecting rod 13 and the first connecting end 9 being stuck together.

[0028] The pull rod 11 includes a connecting portion 15 and a gripping portion 16 . The angle between the connecting portion 15 and the gripping portion 16 is an obtuse angle. Two sides of the connecting portion 15 are respectively connected to the first connecting end 9 and the connecting rod 13 .

A groove 18 is provided on the longitudinal plane for the toggle clamp seat 8 to be adjusted and moved up and down. The toggle clamp seat 8 is fixed to the supporting structure 17 by a fastening bolt, and the fastening bolt passes through the groove 18. The tightness of the fastening bolt is adjusted to make the fastening bolt move in the groove 18, so as to realize the up and down position adjustment of the toggle clamp seat 8, which can meet the detection requirements of different types of objects to be tested.

[0030] The base 1 is provided with a buffer 19 for alleviating the downward pressure rate of the object to be tested, so as to prevent the toggle clamp 5 from generating overpressure on the object to be tested during use, thereby providing a certain buffering effect thereon.

[0031] The base 1 is provided with a longitudinally arranged guide rod 20, and the guide rod 20 is slidably connected to the supporting cross plate 6. In this embodiment, the supporting cross plate 6 is mounted on the guide rod 20, and a linear bearing is provided at the connection between the supporting cross plate 6 and the guide rod 20, which is used to balance the force on the supporting cross plate 6 so that it can be pulled up or pressed down along the guide rod 20.

[0032] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
