Meanwhile, as the telescopic support piece 200 can be telescopic, the suspension height of the gear oil pump 400 can be adjusted through the telescopic support piece 200 according to actual needs, so that students can conveniently measure and observe the gear oil pump 400, the flexibility is high, the students can accurately select proper view directions, the study effect of the students is avoided being influenced, the gear oil pump 400 is suspended, the positioning pin of the gear oil pump 400 is convenient to detach, and the gear oil pumps 400 with different sizes can be fixed through adjusting the positions and the heights of the telescopic support piece 200 and at least three telescopic pressing pieces 300, so that the application range is wide, and the practicability is high.

Preferably, both the side of the pressing plate 310 facing the bottom plate 100 and the side of the supporting plate 210 facing away from the bottom plate 100 may be provided with an anti-slip pad 500, and the anti-slip pad 500 can enable the gear oil pump 400 to be clamped more firmly, reliably and stably, so as to avoid poor clamping stability of the gear oil pump 400 caused by sliding displacement due to small contact friction force between the pressing plate 310 or the supporting plate 210 and the gear oil pump 400.

The telescopic pressing piece 300 can realize the extension, optionally, the telescopic pressing piece 300 includes first base 330, lifter 340, rubber strip 350 and clamping handle 360, first mounting hole 331 has been seted up at first base 330 top, the bar step groove 332 with first mounting hole 331 intercommunication has all been seted up to the both sides that first base 330 is on the back, the bottom of first base 330 is provided with spacing slider 320, the one end of lifter 340 inserts first mounting hole 331, and sliding fit, the other end is provided with clamp plate 310, the both ends of rubber strip 350 are fixed in respectively on the step face 333 of bar step groove 332, clamping handle 360 rotatable setting is in bar step groove 332, rubber strip 350 is located between clamping handle 360 and lifter 340, clamping handle 360's cam end 361 can support rubber strip 350 to lifter 340.

When the telescopic pressing piece 300 needs to be telescopic, the clamping handles 360 on two opposite sides of the first base 330 are driven to rotate, so that the cam ends 361 do not need to abut against the rubber strips 350 to the lifting rods 340, namely, the rubber strips 350 are in clearance fit with the lifting rods 340, the lifting rods 340 can slide in the first mounting holes 331 without the limitation of friction force of the rubber strips 350, the height of the lifting rods 340 is adjusted, after the height of the lifting rods 340 is adjusted to a required position, the clamping handles 360 are driven to rotate, so that the cam ends 361 abut against the rubber strips 350 to the lifting rods 340, and the lifting rods 340 are limited to slide in the first mounting holes 331 through the friction force between the rubber strips 350 and the lifting rods 340, so that locking of the lifting rods 340 is achieved. Through this kind of flexible adjustable mode, novel structure, and can convenient control, convenient operation, the reliability after the locking is high.

Because the friction force between the rubber strip 350 and the lifting rod 340 limits the lifting rod 340 to slide in the first mounting hole 331, locking of the lifting rod 340 is achieved, in order to further improve reliability after locking, the lifting rod 340 can also slide after locking is avoided, optionally, transverse anti-skid patterns can be formed on the surface of the lifting rod 340, friction force between the rubber strip 350 and the lifting rod 340 is increased through the anti-skid patterns, reliability after locking is further improved, the lifting rod 340 can also slide after locking is avoided, and clamping reliability and stability of the gear oil pump 400 are prevented from being influenced due to sliding.
