The working principle of the invention is:
The present invention relates to a kind of English teaching outpost formula testing apparatus, before use, test program is stored in control mould
In block 12, user carries out break-through formula test by touch screen 15, and next topic can just be carried out every time by answering questions, and can be obtained immediately
Know answer correctness, quick error correction study can be carried out, and two touch screens 15 are mutually indepedent, user can carry out answer
Racing match, improves the novelty of test, and when in use, battery 4 itself deposits electricity and powers for equipment, avoids powering off damage suddenly
Bad control module 12, blower 3 are drained, and air are introduced inside outline border from filter screen 13, successively to control module 12 and storage
Battery 4 cools down, and protects to internal electrical equipment, and swing rod 16 can be swung around half round frame 18, the card on touch screen 15
Pin 2 cooperates the adjustable angle of card holder 14, and when not in use, the screen of touch screen 15 can be placed downward, and pressure spring 23 is logical
It crosses swing rod 16 to fix 15 position of touch screen, touch screen 15 is protected, when needing to carry out height adjustment, control electromagnet
34 power-off, reset spring 45 by snap-gauge 33 reset with groove ring 44 be detached from be clamped, motor 8 be lock shaft motor, avoid snap-gauge 33 with
Groove ring 44 is detached from moment and the phenomenon that 24 rotation of shaft occurs, and clamping motor 8 drives shaft 24 to rotate, by the first drawstring 5 and the
Two drawstrings 11 are coiled in 24 outside of shaft, and when shaft 24 rotates, counter 37 measures 24 turnning circle of shaft, and every rotation is certain
Enclose number, hydraulic cylinder 41 just carries out elongation or shortening movement, control backgear 40 and front gear 26 alternately with driving wheel 35 and from
The engagement connection of driving wheel 27, so that 30 rotation direction timing reversing of screw rod, cooperates guide rod 39 and guide sleeve 42 to make by feed screw nut 29
Shell 43 or so moves back and forth in obtaining, and the first drawstring 5 and the second drawstring 11 are uniformly divided when being coiled in 24 outside of shaft
Cloth avoids the company of strand, guarantees the reliability of withdrawing rope, how many circles are wherein rotated in shaft commutates and measured by experiment,
When winding rope, the rope length outside lower casing 9 shortens, and middle bar 6 is above mentioned, outline border 1 is increased, otherwise reduces, to device
Height adjustment is carried out, after adjusting, the absorption of snap-gauge 33 is connected to 44 inner wall of groove ring by the work of electromagnet 34, by shaft 24
Position height, prevent using when move, after use, device power-off, electromagnet 34 power off, motor 8 will height will arrive
It is minimum, guarantee to place and stablize, the present apparatus carries out English-Assisted Instruction to student, more there is a novelty and timeliness, improve teaching at
Effect；This teaching auxiliary device stable structure, it is perfect to the main component protection of itself, guarantee device later period service life；Device
Adjust automatic and stablize, be not susceptible to adjust it is unsmooth or even the problem of can not adjust, it is easy to use.
