Specific embodiment:

For the technical characterstic of this programme can be clearly described, below by specific embodiment, and combine its accompanying drawing, to this Bright it is described in detail.

Embodiment 1:

As Figure 1-4, a kind of portable catapult, including on front side of be provided with the handle 2 of the hollow setting holding groove 1, in handle 2 Top is flexibly connected a bow frame 3 by bearing, is provided with a bow by fixing bolt, in the bottom of handle 2 on bow frame 3 It is provided with a wrist support connecting seat 4, wrist support upper end is flexibly connected with wrist support connecting seat 4, the bottom of described wrist support connecting seat 4 and handle 2 It is flexibly connected, the lower locking device being matched with wrist support connecting seat 4 is provided with handle 2, handle 2 is provided with and bow frame 3 The upper locking device matching.

The upper end of wrist support connecting seat 4 is stretched into inside handle 2, on wrist support connecting seat 4 lateral wall within handle 2 circumferentially Direction is provided with a toroidal cavity 5, and the location interval corresponding to toroidal cavity 5 on the medial wall of handle 2 is provided with several Link stopper 6, block 6 is placed in toroidal cavity 5.Handle 2 and the relatively turnable connection of wrist support connecting seat 4, handle 2 can basis The wrist angle of people is rotated at random, and makes to hold groove 1 and finger no-float all the time, the comfort level of hand-held handle 2 on handle 2 Height, meanwhile, no matter how wrist angle changes, all can ensure that wrist support, all the time on arm, prevents hand shaking it is ensured that taking aim at ejaculation Degree.

Corresponding lower solid in the position with toroidal cavity 5 that described lower locking device includes being located on handle 2 rear wall Determine screw 7, the head of lower fixing screws 7 stretches in toroidal cavity 5 through handle 2.User finds comfortable handle 2 Angle after by lower fixing screws 7, handle 2 can be fixed, the lower fixing screws 7 of rotation by the head of lower fixing screws 7 with The diapire of toroidal cavity 5 abuts, and is not required to every time handle 2 and all adjusts handle 2 angle, more convenient to operate.

Two fixed grooves 8 on bow frame 3 that described upper locking device includes being located in handle 2,8 points of two fixed grooves It is not symmetrically set on the leading flank and trailing flank of bow frame 3, fixing screws 9 on, upper fixation are provided with the rear wall of handle 2 The head of screw 9 stretches in fixed groove 8 through handle 2.When needing bow frame 3 is locked, bow frame 3 is rotated root According to needing to make one of fixed groove 8 relative with upper fixing screws 9, by the head of upper fixing screws 9 is screwed in anchor In groove 8, bow frame 3 is locked, the upper locking device in the present embodiment can achieve the locking of 3 two positions of bow frame, is not required to During locking, the head of upper fixing screws 9 is screwed out fixed groove 8.

Described bow includes the arch head bracket 14 of y type, and arch head bracket 14 is connected by fixing bolt with bow frame 3, bow The rubber band frame 24 being respectively provided on two sides with font on the one of support 14, one end of rubber band frame 24 is cut with scissors by bearing pin with arch head bracket 14 Connect, the other end of rubber band frame 24 is provided with the roller 15 installing rubber band, divides near one end both sides of bearing pin in rubber band frame 24 lateral surface It is not provided with a foresight projection 16.Above-mentioned bow is the bow needing during a kind of use with respect to handle 2 rotation.

It is provided with optical fiber bar groove 17 at the middle part of rubber band frame 24 lateral surface along the length direction of rubber band frame 24, recessed in optical fiber bar It is provided with optical fiber bar, optical fiber bar auxiliary aims at, and improves and takes aim at ejaculation degree in groove 17.

It is respectively provided on two sides with one in rubber band frame 24 lateral surface and take aim at phase along what rubber band frame 24 length direction was extended with laser Cooperation dovetail groove 18, by dovetail groove 18, laser is taken aim at and is loaded on bow, make to take aim at penetrate more convenient.

Described wrist support includes the type of falling a l bracing frame 19, and the quarter butt of the type of falling l bracing frame 19 is actively plugged in wrist support connecting seat 4 On, it stretches out the spacing jump ring 20 of end clamp one in wrist support connecting seat 4 outside, the rear end side of the stock of the type of falling l bracing frame 19 It is fixed with a curved support pad 21 relative with handle 2 position, on the wrist support connecting seat 4 on rear side of the quarter butt of l type bracing frame 19 Be provided with a spacing pin 22 being located at stock front upper, the described type of falling l bracing frame 19 and curved support pad 21 integrally casting and Become.In addition, existing wrist support includes left and right two bracing frames and is arranged on supporting pad between two bracing frame rear ends, this wrist support Wear and during catapult, need bimanualness, complex operation, it is impossible to quick donning, take off catapult, is not particularly well suited for emergency.This There is the type of falling a l bracing frame 19 wrist support only side in invention, can realize wearing of catapult by one hand, and flexible operation, simplicity can Quick donning, take off catapult, be particularly suited for emergency.

It is provided with the caging bolt 23 matching with spacing pin 22 in the stock front portion of the type of falling l bracing frame 19.Existing wrist Support is so that it is secured firmly on the arm of user by spacing pin 22, and the angle between wrist support and handle 2 is fixing, The requirement to different angles for the different catapult user cannot be met.Catapult of the present invention passes through spacing pin 22 and caging bolt 23 Cooperation makes wrist support be secured firmly on the arm of user, and can be by adjusting caging bolt 23 top and the type of falling l bracing frame The distance between 19 stock surface is realized adjusting the purpose of the angle between handle 2 and wrist support.

Catapult of the present invention can be adapted to various with respect to handle 2 rotation and non-rotary bow, using rotation bow when, Do not need using upper locking device, bow frame to be locked, non-rotatable bow to be used, such as spring-loaded bow are (such as Shown in Fig. 5) and steel ball accelerate bow (as shown in Figure 6) when, using upper locking device, bow frame 3 is locked.

Embodiment 2:

As Figure 7-9, the present embodiment and the difference of embodiment 1 are: described upper locking device includes same being located in and holds The regular prism 10 on the bow frame 3 in 2, the seamed edge of regular prism 10 is abutted with the medial wall of handle 2, is provided with one in handle 2 Inserting column 11, the lower end of inserting column 11 is placed in regular prism 10 and the gap of medial wall formation of handle 2, in the rear wall of handle 2 It is provided with a chute 12, a slider 13 activity is installed in chute 12, slider 13 is connected with the upper end of inserting column 11.Need to bow When frame 3 is locked, lower sliding button 13, inserting column 11 is placed in regular prism 10 and the gap of medial wall formation of handle 2, to bow The headstock 3 is locked, and the upper locking device in the present embodiment can achieve the fixation of more than 3 angle of bow frame, when being not required to locking, on Sliding button 13, bow frame 3 can be freely rotatable with respect to handle 2.

The present invention does not describe part in detail, is the known technology of those skilled in the art of the present technique.
