[0036] The transmission structure 3 includes an L-shaped plate A301, a multi-stage hydraulic cylinder body 302, an L-shaped plate B303, a motor body 304, and a transmission shaft connector 305. The L-shaped plate A301 is bolted to the platform on the frame 1. The multi-stage hydraulic cylinder body 302 is arranged in the transverse section of the L-shaped plate A301, and the multi-stage hydraulic cylinder body 302 is selected and used by the technical personnel of this profession according to the actual situation. The transverse section of the L-shaped plate B303 is connected to the outer end of the multi-stage piston rod of the multi-stage hydraulic cylinder body 302. The motor body 304 is fixed in the transverse section of the L-shaped plate B303, and the motor body 304 is selected and used by the technical personnel of this profession according to the actual situation. The output shaft of the motor body 304 passes through the longitudinal end of the L-shaped plate B303. The transmission shaft connector 305 is arranged on the output shaft of the motor body 304. The transmission shaft connector 305 corresponds to the detection channel entry port on the detection machine body 2.

[0037] This utility model, by setting up an L-shaped plate A301, a multi-stage hydraulic cylinder body 302, and an L-shaped plate B303, has the advantage of adjusting the height of the L-shaped plate B303, thereby adjusting the height of the motor body 304 and the transmission shaft connector 305, making it easier to put the transmission shaft into the testing channel and connect it with the raised transmission shaft connector 305, thus solving the problem of some inconvenience when installing the transmission shaft into the testing channel.

[0038] Specifically, the two sides of the longitudinal section of L-shaped plate B303 are connected to the longitudinal section of L-shaped plate A301 via connecting components 306;

[0039] The connecting assembly 306 includes a connecting block A3061, a connecting block B3062, and a connecting rod 3063; the connecting block A3061 is fixed to the side end of the longitudinal section of the L-shaped plate A301; the connecting block B3062 is fixed to the side end of the longitudinal section of the L-shaped plate B303; the connecting rod 3063 passes through the connecting block B3062; wherein, the bottom end of the connecting rod 3063 is fixedly connected to the connecting block A3061.
