In this embodiment, refer to Figure 2 , three first connection bits 211 are set, and one second connection bit 212 is set.

Since different types of injectors need different liquid flow rates when being inspected, the connecting pipe 31 can at least include a first connecting pipe 311 and a second connecting pipe 312. The first connecting pipe 311 can be communicated with the injector 4 to be inspected on the first fixing base 215, and the second connecting pipe 312 can be communicated with the injector 4 to be inspected on the second fixing base 216, so as to transport the inspection liquid under corresponding conditions to different injectors through different connecting pipes 31. Of course, in other embodiments, the number of the fixing bases 21 can also be more, which can be determined according to the actual situation, and the present disclosure does not limit this.

The other two interfaces of the three-way valve 314 are respectively connected to the first connecting pipe 311 and the second connecting pipe 312, so that the staff can control the liquid delivery to the injector 4 to be detected through different connecting pipes 31 by means of the three-way valve 314. The control method can be to set the three-way valve 314 as an electronic type to control the communication between the main pipe 313 and different connecting pipes 31, or other control methods well-known to those skilled in the art, which will not be elaborated herein too much.

[0031] In an embodiment of the present disclosure, referring to Figure 1 and Figure 3 , the injector detection device of the present disclosure further includes a power supply component 6 and a control component 7.

The power supply component 6 can be a battery pack or a rechargeable battery, etc. The control component 7 is connected to the injector 4 to be detected and can include a controller, a switch, etc., and can control the opening and closing of the injector 4 to be detected, so that the staff can detect the injector 4 to be detected according to the actual situation.

[0032] When the injector detection device of the present disclosure is in use, different fixing seats 21 can be selected for connection according to the types of different injectors 4 to be detected. After the detection starts, the connecting pipe 31 communicating with the injector 4 to be detected can be controlled by the three-way valve 314 to deliver liquid to the injector 4 to be detected and the comparison injector 5. The staff can judge the fault condition of the injector 4 to be detected by observing the liquid ejected from the injector 4 to be detected and the comparison injector 5 in the detection member 22, that is, the oil pipe. The whole process of the injector detection device of the present disclosure does not require installing the injector into the detection vehicle, the labor intensity of the staff is relatively low, the detection efficiency is high, and the liquid for detecting the injector can also be glass water or other liquids with high safety, so as to avoid safety accidents during the detection.
