[0024] By the cooperation between first locating block 2, second locating block 3 and third locating block 4, the rear section, middle section and front end of the compressor are supported to achieve balanced support, so that the positioning of the compressor is more accurate and stable, and the positions of first stand 9 and second stand 7 are set to adapt to the air inlet and exhaust port of the compressor, and the length of air inlet compression mechanism and exhaust port compression mechanism is set to 1 / 4 of the length of base 1 to adapt to the compressor with certain deviation of air inlet and exhaust port.
[0025] Air inlet compression mechanism includes notch 10, first lever 13, first limit dead point 14, first eccentric cam 11 and first handle 12, the bottom of notch 10 is rectangular plate, two long sides are vertically fixed with two fixed blocks on the right side, the fixed blocks have grooves, first limit dead point 14 is on the right side of the grooves, first lever 13 is composed of two cuboids, the wide cuboid is on the left side of the narrow cuboid, the wide cuboid is provided with sliding block and groove, first lever 13 left side has notch and first eccentric cam 11, first eccentric cam 11 is provided with first handle 12;Exhaust port compression mechanism includes platform 8, second lever 15, second limit dead point 16, second handle 17 and second eccentric cam 18, platform 8 is rectangular plate, two long sides are vertically fixed with two fixed blocks on the left side, the fixed blocks have grooves, second limit dead point 16 is on the left side of the grooves, second lever 15 is composed of cuboid on the left side and square on the right side, the cuboid is provided with sliding block and groove, second lever 15 right side has notch, second eccentric cam 18 and notch are matched, second eccentric cam 18 is provided with second handle 17;First lever 13 right side and second lever 15 left side are provided with press pin 19, press pin 19 vertically penetrates first lever 13, second lever 15 and first block head 5, second block head 6 bottom bolt connection, first block head 5 and second block head 6 bottom are provided with simulation pipeline port.
[0026] The mutual adaptation of the slot 10 and the first lever 13, the platform 8 and the second lever 15 enables the device to be adapted laterally according to the specific positions of the compressor air outlet and the exhaust port. The first lever 13 is a narrow cuboid with the right side because the air inlet is on the side. The slot 10 and the first lever 13 are both fixed obliquely. The oblique fixing can also be provided with a rotating shaft and a fixed block in the middle to increase the adaptation ability of the device. The flexibility of the narrow cuboid is better than that of the wide cuboid when the first eccentric cam 11 is used for compression, which is more convenient for clamping. The first limit dead point 14 and the second limit dead point 16 are circular through holes with a diameter higher than the height of the sliding groove. When the first eccentric cam 11 and the second eccentric cam 18 are driven by the first handle 12 and the second handle 17 to make the first lever 13 and the second lever 15 upwardly tilt on the handle side to a height equal to the diameter of the first limit dead point 14 and the second limit dead point 16, the first block head 5 and the second block head 6 on the other side will have a downward force under the action of the lever principle, that is, the compression effect.

The other side of the bolt is adapted to the threaded hole on the compressor. The left side of the first positioning block 2 is provided with a baffle. The internal widths of the third positioning block 4, the second positioning block 3 and the first positioning block 2 are adapted to the compressor.
[0028] The distance between the first positioning block 2, the second positioning block 3 and the third positioning block 4 is limited, and the position on the base 1 is determined, so as to better ensure the accuracy of clamping of the clamping assembly. The inner surface of the second positioning block 3 is annularly provided with a spiral hole, and a bolt is arranged on the spiral hole. The other side of the bolt is adapted to the threaded hole on the compressor. The left side of the first positioning block 2 is provided with a baffle, so as to ensure the stability of the bottom and avoid sliding and affecting the effect. Only two bolts are used in the whole process, the operation is more convenient and fast, and the detection efficiency is improved.
[0029] Specific implementation principle: when using the device, first determine the inlet and outlet position of the compressor to be detected, which should be on the vertical parallel line of the first head 5 and the second head 6, confirm the position, place the compressor on the first positioning block 2, the second positioning block 3 and the third positioning block 4 of the base 1, and fasten it through the bolts inside the second positioning block 3 and the bolt holes on both sides of the compressor. The operator horizontally pushes the first handle 12 and the second handle 17 to make the first lever 13 and the second lever 15 close to the middle of the compressor. When the slider moves to the first limit dead point 14 and the second limit dead point 16, the first head 5 and the second head 6 are just above the inlet and outlet. By rotating the first eccentric cam 11 and the second eccentric cam 18 through the first handle 12 and the second handle 17, the slider enters the top of the first limit dead point 14 and the second limit dead point 16. The first lever 13 and the second lever 15 make the first head 5 and the second head 6 press the inlet and outlet downward to realize the function of fast clamping. The whole process is simple to operate, which is beneficial to improve the detection efficiency of the compressor.
