An opening 14 is formed in the circumferential surface of the barrel body 10, and the opening 14 is adjacent to the entrance port 12. In the embodiment, the opening 14 has a rectangular shape from the side and has a continuous closed periphery. However, in other possible embodiments, the periphery of the opening may also have an open side.

The inner wall of the barrel body 10 is further provided with at least two chutes 40. The two adjacent chutes 40 extend obliquely downward from the axial direction of the barrel body 10 from the radial direction of the barrel body 10. The two adjacent chutes 40 define a contact area 80 for the sub-elastic member 30 to abut against each other. More specifically, the adjacent side systems of the adjacent two of the chutes 40 each have a beveled edge 81 adjacent to each other. The beveled edge 81 can define the abutment region 80, and the area of the abutment region 80 is tapered along the inward direction of the entrance port 12, and the abutment region 80 can have, for example, a substantially triangular profile. In the present embodiment, the barrel body 10 is provided with two inclined grooves 40, and the two inclined grooves 40 are disposed on opposite sides of the opening 14. The two inclined grooves 40 are symmetrically disposed opposite to the opening 14, and The two chutes 40 are spaced apart from one another.

Further, each of the chutes 40 is integrally recessed on the inner wall of the barrel body 10 and extends toward the inside of the barrel body 10 in an extending direction, and the extending direction is not associated with the barrel body 10. The axial direction is parallel. In the embodiment, each of the chutes 40 can be inclined gradually along the extending direction. And one end of each of the chutes 40 can be opened at the entrance port 12, and each of the chutes 40 can have an arc tip 41 facing the other end of the barrel body 10, and the two arc tips 41 are spaced apart from each other. The two arc tips 41 are respectively disposed in opposite directions and may have an angle 42 between them, and the angle 42 may be, for example, 60 degrees. However, in other possible embodiments, the angle 42 may also be 45 degrees. 90 degrees or can be adjusted to any other angle according to your needs.

In the present embodiment, the barrel 1 may further include a sleeve 50 disposed on the barrel body 10, and the cutting portion 20 is protruded from the inner peripheral wall of the collar 50. The cutting portion 20 is paired. The opening 14 is to be embedded in the opening 14 and can be partially moved into the channel 11 for tangentially rubbing the surface of the bullet member 30. Further, the opening 14 is provided At the top end of the bullet member 30, the cutting portion 20 can be in frictional contact with the top end of the bullet member 30. The cutting portion 20 and the collar 50 can be integrally formed and can be, for example, a flexible material such as rubber. . The cutting portion 20 can include at least two projections 21 extending into the passage 11 for tangentially rubbing the surface of the sub-elastic member 30.

The outer surface of the barrel body 10 can be recessed with at least one assembly groove 16 .

Stability.

In actual use, the cutting portion 20 can be pushed into the pipe 11 to be pushed and moved. For example, when the bullet member 30 enters the passage 11 through the bullet port 12, the cutting portion 20 can be, for example. The cutting portion 20 is pushed by external pressing so that the cutting portion 20 can abut against the bullet member 30 and generate a frictional force on the surface of the bullet member 30, and the bullet member 30 is subjected to the cutting. The abutting portion of the moving portion 20 is moved against the abutting region 80 by friction, and a bottom surface of the chute 40 forms a venting gap 43 with the surface of the bullet member 30. More specifically, the surface of the bullet member 30 can abut against the abutment region 80, and the effect of stabilizing the support can be produced, and when the bullet member 30 is pressed toward the ejection port 13, the bullet The member 30 is rotated in one direction due to friction with the cutting portion 20 (as shown in FIG. 6), and the venting gap 43 is available for airflow to further drive the sub-elastic member 30 to rotate. It is worth mentioning that the area of the contact area 80 is gradually reduced toward the exit port 13 , so that between the sub-elastic member 30 and the abutment region 80 during the movement of the bullet member 30 toward the ejection port 13 The friction system is gradually reduced, and the sub-elastic member 30 can be further made to have a better rotation effect.

According to the above, the two ventilation gaps 43 are respectively provided for two airflows, and when the two airflows respectively flow through the two ventilation gaps 43, the two airflow systems can contact the surface of the bullets 30. At the same time, the bullet member 30 can be rotated, because the two chutes 40 extend toward each other, so that the two air flows have a tendency to meet each other, so that the two air flows are generated at the bottom end of the bullet member 30. The superimposed cyclone thrust is used to rotate the sub-elastic member 30.

It is worth mentioning that the force that the bullet member 30 is pushed by the cutting portion 20 is evenly distributed to the abutment region 80, and the airflow through the two chutes 40 is made to stabilize the bullet member 30. The ground is guided and beared in the barrel body 10 to produce an optimal rotation effect for stably guiding the bullet member 30 and substantially effectively increasing the range and reducing the occurrence of errors.

The barrel body 10 is adjacent to the outer peripheral surface of the bullet port 13 and is provided with a plurality of vent holes 60. Further, the vent holes 60 can guide the airflow inside the barrel body 10, and the barrel is lowered. The pressure inside the body 10 causes a stable flight effect when the bullet member 30 is fired. For example, the vent holes 60 are radially disposed around the barrel body 10 on the circumferential surface of the barrel body 10, Further, the barrel body 10 may further include at least one guiding groove 61 disposed between the ejector opening 13 and each of the vent holes 60. The guiding groove 61 is recessed on the circumferential surface of the barrel body 10, One end of the guiding groove 61 communicates with the vent hole 60, and the other end extends to the side of the ejector opening 13 to form an opening. The ejector opening 13 can be provided with an inwardly tapered tapered opening 62.

In another embodiment, as shown in FIG. 8 to FIG. 9 , the barrel 1 a can also include an assembly block 70 embedded in the opening 14 , and the cutting portion 20 a can be protruded from the assembly block 70 , and The assembly block 70 is pushed by an external force in such a manner that the cutting portion 20a abuts and rubs the bullet member to cause the bullet member to rotate.

In summary, the barrel of the present invention can circulate the bullet through the airflow flowing through the chute, thereby generating a stable balance effect, and substantially effectively increasing the range and reducing the error; The airflow can generate a cyclone thrust at the bottom end of the bullet to rotate the bullet and produce an optimal rotary cutting effect. In addition, a plurality of vent holes can be provided for diverting the airflow inside the barrel and producing a stable flight effect.
