Among the figure: 1. left catapult arm 2. half slots 3. limited blocks 4. half slots 5. right catapult arm 6. bearing pins 7. involute gear tooths 8. hinge seats 9. screwed holes 10. snap rings 11 circular hole .12. snap rings 13. knobs 14. end caps 15. miniature storage box 16. box handle 17. screw rods 18. involute gear tooths 19. bearing pins.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Like Fig. 1, shown in 2; Said left catapult arm 1 is installed on the hinge seat 8 through bearing pin 19; Right catapult arm 5 is installed on the hinge seat 8 through bearing pin 6, and the lower end of left catapult arm 1 is processed with involute gear tooth 18, and the lower end of right catapult arm 5 is processed with involute gear tooth 7; The gear teeth 18 and 7 of two arms are engaged with each other, and can make two arms realize synchronous convergent-divergent.

As shown in Figure 2, two snap rings 10 and 12 are housed on the screw rod 17, can guarantee the axial location when screw rod 17 is installed in the circular hole 11 of handle 16, when being rotated, screw rod 17 do not produce moving axially of relative handle 16 in handle 16.Hinge seat 8 is installed in the handle 16, and the restriction that receives the handle profile can only be moved in handle 16, can not be rotated; Because external screw thread and the screw on the hinge seat 89 on the screw rod 17 are screw fit, can drive hinge seat 8 when then screw rod 17 rotates and move up and down.

As shown in Figure 2, the upper end of handle 16 is equipped with limited block 3, and the both sides of limited block 3 are the inclined-plane of 45 degree.Knob 13 is equipped with in the lower end of screw rod 17, when turning knob 13 drives screw rod 17 rotations, hinge seat 8 is moved up in handle along screw rod 17, stops when running into limited block 3 moving; Meanwhile, left catapult arm 1 is launched into 90 degree to both sides with right catapult arm 5 under the guiding on limited block 3 inclined-planes, and involute gear tooth 18 on left catapult arm 1 and the right catapult arm 5 and 6 engagement have reached the limit of the position, have limited the maximum start point of two arms.

Like Fig. 3, shown in 4, the inboard of left catapult arm 1 is provided with the groove 2 of a semicircular arc, and the inboard of right catapult arm 5 is provided with the groove 4 of a semicircular arc.When turning knob 13 made hinge seat 8 move down on earth, left catapult arm 1 just can be drawn close to screw rod 17 with right catapult arm 5 and be retracted in the handle; At this moment, vacate the groove of a circle between left catapult arm 1 and the right catapult arm 5, can not interfere with screw rod 17.

Like Fig. 2, shown in 4, the lower end of handle 16 is provided with a miniature storage box 15, and end cap 14 is installed on the casing, can deposit catapult rubber band and a small amount of hoodle.

In Fig. 2, the embodiment shown in 4, be under the state of " I " in that the utility model is folding, the user only need use hand turning knob 13; Driving threaded rod 17 rotates; Drive hinge seat 8 and move up, then two catapult arms 1 are with 5 under the effect of limited block 3, outwards launch along 45 profiles of spending.When hinge seat 8 upwards is pushed into limited block 3 places by screw rod 17; The lower end that corrects on the hinge seat 8 limited 3 props up; Simultaneously the gear teeth 18 and 7 of two catapult arms 1 and 5 lower ends are engaged with each other and reach the limit of the position and can't be rotated further, and promptly two catapult arms have been in complete deployed condition (as shown in Figure 2) at this moment.The user can open end cap 14, installs from the miniature storage box 15 interior rubber band and the hoodles that leave the inside in of taking out, and can normally use the utility model by normal mode.

When catapult is finished using; Can unload rubber band, rubber band and remaining hoodle are placed in the miniature storage box 15, simultaneously turning knob 13; Make hinge seat 8 move down and get back to the home position; Can merge two catapult arms 1 that separate and 5 this moment, and then the utility model is folding fully is " I " shape (as shown in Figure 4), and the user can carry the utility model very easily.

The above is used to explain the utility model, but is not used for limiting the scope of the utility model.Under the prerequisite that does not break away from the utility model know-why, the utility model can also be made some modifications and variation, and these modifications and variation also are regarded as the protection domain of the utility model.
