Detailed description of the invention
As shown in Figure 1 and Figure 2, pitching gauche form variable force catapult described in the utility model includes handle 1 and is arranged on hands
The bow body of handle upper end, described bow body includes symmetrically arranged left bow body 21 and right bow body 22, described left bow body 21 and right bow body 22
Lower end by bow body connecting rod 23 be fixed together, described bow body is provided with rubber band 3, the centre of described rubber band 3
It is provided with bullet pocket 4, left bow body 21 and right bow body 22 can have left socle 5A and right support 5B by pitching ground hinge by rotating shaft respectively.
Structure as shown in Figure 1 can be used, the rotating shaft that horizontal direction extends, this turn are set in the outside of left socle 5A and right support 5B
Axle is vertical with the axis of left bow body 21 or right bow body 22 and is rotatably inserted into left bow body 21 or right bow body 22；Certainly
Other connected mode can also be used, as long as enabling left socle 5A and right support 5B pitching.Described left socle
5A and right support 5B is symmetrical arranged, on left socle 5A and right support 5B all with support junction point, longitudinally disposed hinge 6 and
Horizontally disposed pulley 8, described support junction point is positioned at the front of hinge 6, pulley 8 is positioned at the rear of hinge 6, described hinge 6
On connecting lever 7 is installed, described connecting lever 7 has two and fixing connects armed levers at an acute angle, and wherein the second armed lever 73 is drawn by elasticity
Stretching part 11 to be connected on support junction point, rubber band 3 is walked around pulley 8 and is fixedly connected on the first armed lever 72 of connecting lever 7.Pulley 8
Play the effect of location rubber band 3, it is ensured that the connecting lever 7 of both sides balances, symmetrical stress, can also be driven by rubber band 3 simultaneously
Left socle 5A and right support 5B pitching deflection, beneficially fine sight.Certainly, as another embodiment of the present utility model, also
Can be without pulley 8.
This elastic stretching part 11 can use extension spring as shown in Figure 1 and Figure 2, it would however also be possible to employ elastic skin as shown in Figure 3
Muscle.The when that rubber band 3 stretching backward, traction connecting lever 7 rotates, tensile elasticity tensioning member 11 simultaneously.Connecting lever 7 changes the when of rotation
Become tensile elasticity tensioning member 11 and the deflection angle of rubber band 3 front end, the most just change deflection torque and rubber band 3 simultaneously
Enhanced stretch resistance.Can suitably increase rubber band 3 by the length and angle rationally arranging 7 liang of armed levers of connecting lever and stretch the initial stage
The resistance of resistance, the most suitably reduction stretching later stage, alleviates arm stress, beneficially fine sight.
Left socle 5A and right support 5B is fixed together by connecting plate 20, so can make left socle 5A and the right side
Frame 5B synchronizes deflection.
As in figure 2 it is shown, described connecting lever 7 includes sleeve pipe 71 that slip cap is contained on hinge 6, is arranged on the of sleeve pipe 71 upper end
One armed lever 72 and be arranged on the second armed lever 73 of sleeve pipe 71 lower end, described first armed lever 72 and the second armed lever 73 are on sleeve pipe 71
Position there is difference in height.The when that connecting lever 7 so can being avoided to rotate, two armed levers interfere.
As illustrated in the embodiment of figure 3, described connecting lever 7 is fixedly connected on hinge 6, and hinge 6 is rotatably installed in support 5
On, described first armed lever 72 and second armed lever 73 position on hinge 6 have difference in height.
It addition, as in figure 2 it is shown, be fixedly installed sight 9 on the outer wall of described left socle 5A and right support 5B.This aiming
Device 9 can use electronic laser sight, it would however also be possible to employ machinery foresight formula sight.
On described handle 1, slip cap is equipped with sliding sleeve 10.Bow body 2 can swing with the change of 3 liang of side draws of rubber band,
All the time keep vertical with aiming line, be conducive to improving the accuracy of shooting.
