Face;Distance is more than the outer diameter of a bullet between 1 lower face of the crotch upper surface and holding axis.Preferably:On the crotch
Surface is arc-shaped concave surface, so as to preferably position bullet.Specifically:Holding 1 lower ending opening 13 of axis is additionally provided with one
Catch 72, the catch 72 are less than the diameter of any one bullet, which cooperatively forms with bullet positive stop hook 7 only allows one
The structure that bullet is taken out.
The above-mentioned holding axis 1, bullet rope support 2 and limitting casing 3 can be made of any one material, and bullet then needs
It is made of metal material, so as to fulfill magnet to the adsorption capacity of bullet, in the present embodiment, the holding axis 1 plays rope support 2, limiting
Frame 3 and bullet are made of stainless steel, so as to effectively improve the service life of catapult frame.
A kind of catapult, including elastic stretching part(It is not shown)And above-mentioned catapult frame;Elastic shelf in the catapult frame
Limiting section is the cyclic structure with opening, and emulsion tube rubber band can be caught in by compression in cyclic structure;In addition, in order to improve catapult
The accuracy of strike is additionally provided with the distance scale for aiming in the upper bullet rope support of catapult frame.
There are mainly two types of the emulsion tube rubber bands for being used for catapult currently on the market, and one kind is in the respectively connection one of catapult pocket both ends
Emulsion tube rubber band forms the rubber band with both ends;Another kind is the both ends of the both ends connection same root emulsion tube rubber band of catapult pocket,
Form the rubber band of closed circular.Above two emulsion tube rubber band is applicable in the catapult of the present embodiment.When using the breast with both ends
During sebific duct rubber band, by emulsion tube rubber band both ends be connected respectively to play rope support 2 limiting section 21 on, when need adjust emulsion tube rubber band
During length, both ends are distinguished again to the spacing ring 32 of limitting casing 3, you can change the effective length of emulsion tube rubber band, adapt to different length
Degree demand;When the emulsion tube rubber band for using closed circular, three positions for choosing emulsion tube rubber band are respectively clamped into elastic shelf
3 one of spacing ring 32 of limiting section 21 and limitting casing, when stretching rubber band, the emulsion tube rubber band of closed circular can be in pulling force
Effect is lower to be automatically adjusted, and the effective tensile elongation for making two elastic bow shape arms is equal, by different spacing rings, you can changes emulsion tube
The effective length of rubber band adapts to different length demand.Therefore, using the catapult of the present embodiment, nothing needs to change emulsion tube rubber band, i.e.,
Its length is adjusted, to adapt to different length requirements.
Other than being used as catapult, removing the catapult stent of emulsion tube rubber band can also make the multi-purpose catapult of the present embodiment
The finger tiger that tool is defended for nearly body uses, and can also be used as window breaker use.Therefore, using the catapult of the present embodiment, Neng Goutong
When meet a variety of demands of outdoor enthusiast, realize multi-purpose content.
From the above description of the utility model, it can be seen, relative to the prior art, the utility model has following beneficial
Effect:
1st, in catapult, the effective length of elastic stretching part is from the length for playing rope support 2 to pulling force point;Traditional catapult branch
Frame only has there are one axis 1 is held, and elastic stretching part both ends, which can only be fixed on, to be played on rope support 2, therefore effective length of elastic stretching part
It spends unadjustable;In the technical solution of the utility model, increase limitting casing 3, and several spacing rings 32 are set on limitting casing 3,
When needing to adjust the effective length of elastic stretching part, elastic stretching part need to only be fixed again with spacing ring 32, you can change bullet
Property tensioning member effective length, realize elastic stretching part length adjustment, to adapt to the brachium of different users, and easy to adjust,
It is highly practical;
2nd, by increasing spacing ring 32, when user, which holds, holds axis 1, spacing ring 32 is looped around the fist held with a firm grip and refers to outside,
It holds and fist buckle structure is formed between axis 1 and limit shaft 3;And fixed several spacing rings 32 then form the striking structure of fist button, because
This, in the technical solution of the utility model, catapult frame can use in the defence of nearly body as tiger is referred to;
3rd, using the cyclic structure with opening as limiting section and spacing ring 32, elastic stretching part can pass through the opening
It is caught in cyclic structure, facilitates fixed elastic stretching part, and simple in structure, it is easy to use;
4th, being connected for axis 1 and limitting casing 3 is held, both makes to form the integral structure of closing, strengthens and hold axis 1 and limit
3 stability of frame, meanwhile, shim 31 is affixed in middle section position by the two, and the entirety for improving catapult stent consolidates effect, as
Refer to tiger in use, with more powerful hitting power;
5th, it plays rope support 2 and includes two symmetrically arranged bullet rope arms centered on the line for holding axis 1 and limitting casing, and bullet rope
The free end setting limiting section of arm, when elastic stretching part passes through the limiting section of a bullet rope arm and is fixed on another bullet rope arm
During limiting section, elastic stretching part can under the action of pulling force two bullet rope arm both sides of adjust automatically length, ensure both sides has
It imitates length and elastic force is equal, make catapult strike more accurate, prevent the beating position caused by elastic force is inconsistent from deviateing;
6th, two bullet rope arm free ends in rope support 2 are played and are additionally provided with the distance scale for aiming, to assist user's shoot straight
Target is hit, improves attack precision;
7th, one end integrated illumination device on axis 1 is held, realize catapult stent has illumination functions again, facilitates outdoor sports
When use.
Although the utility model is disclosed as above with preferred embodiment, its be not for limiting the utility model, it is any
Those skilled in the art without departing from the spirit and scope of the utility model, can make possible variation and modification, because
This scope of protection of the utility model should be subject to the range that the utility model claims are defined.
