[0002] According to the previous, the power source of the toy gun in the firing is mainly in the air pressure type and the electric type. The pressure type has evolved from the early air pressure to the use of compressed gas such as gas, and has been in existence for many years. In the past, the toy rushing with the action of pneumatically driving the firing and generating the recoil force mainly relied on gas such as gas to drive the toy gun to operate, and in the rushing machine, the outer tube of the rushing machine was pulled by an elastic component. The inner tube (also known as the gun body and the piston), when the gas pushes the outer tube to the relative displacement of the inner tube, the elastic element is stretched by the pushing force of the gas, and after the gas is interrupted, the The elastic restoring force returns to the position. [0003] However, since the toy gun is continuously subjected to stretching and its natural recovery action in the case of continuous firing, it is liable to be elastically fatigued. In the past, the toy robbing did not provide an assembly structure that was easy to disassemble in the internal structure of the rushing machine, so that the user could not or could not easily replace the elastic member. [0004] In view of this, the creator has improved and solved the above-mentioned shortcomings, and has devoted himself to researching and cooperating with the application of theory, and finally proposed a creation that is reasonable in design and effective in improving the above-mentioned defects. [New Content] [0005] The main purpose of this creation is to provide a toy grabbing structure 10021047$单号A_第4页/20 pages 1013029127-0 M426018 -- 101.01月20日The replacement page is improved in that it provides a toy rush to effectively use gas to drive the machine, and maintains the elastic restoring force of the elastic member for pulling the outer tube and the inner tube, thereby detachably The elastic component is assembled between the inner and outer tubes of the machine for quick replacement by the user or the player. ^

[0006] In order to achieve the above purpose, the present invention provides a structure improvement of a toy grabbing machine, including a grabbing outer tube, a grabbing inner tube, a gas valve and a piston member; and a middle air chamber in the outer tube The inner tube of the rushing machine is placed by the air chamber, and the inner tube of the rushing machine has an air outlet port and a chamber communicating with the air outlet port, and is provided with a communication to the inner side of the outer edge of the inner tube of the rushing machine. The gas valve is located in the inner tube of the rushing machine and is elastically disposed on the air outlet; the piston member is connected between the inner and outer tubes of the rushing machine, and includes a piston sleeve located in the chamber, a set of piston washers disposed at the end of the piston sleeve, and a wearer. a traction elastic member disposed in the piston sleeve, and a traction block pulled to one end of the traction elastic member; wherein the traction block is detachably fixed in the outer tube of the rushing machine, and the other end of the traction elastic member is detachably Set on the inner tube of the machine.

The valve plug 31 exposes the air port 20, and the outer diameter of the valve plug 31 is larger than the outer diameter of the air outlet 20. When the gas such as the gas (not shown) is injected into the machine from the air inlet 22, the air valve 3 can be received. The push of the gas causes the valve plug 31 to block at the air outlet 2 〇β more detailed 10021047^single number Α0101 page 6/total 20 pages 1013029127-0 M426018 January 20, 2011 correction replacement page fine, the gas valve 3 The hollow valve tube 30 is provided with a plurality of annular air holes 300, and the valve plug 31 protrudes into the hollow valve tube 30 into a tapered flow guiding surface 310, so that the gas (not shown) is partially provided by the air holes 300. Entering the air outlet 20, while using the flow guiding surface 310 to increase the fluency of the gas (not shown) into the air outlet 20 .

[0012] The piston member 4 is connected between the outer tube 1 and the inner tube 2, and includes a piston sleeve 40, a set of piston washers 41 disposed at the end of the sleeve 40, and a piston a traction elastic member 42 in the sleeve 40, and a traction block 43 that is pulled to the end of the traction elastic member 42; wherein the piston sleeve 40 is nested forwardly from the rear of the chamber 21 of the inner tube 2, and is fixedly located In the chamber 21, a hollow receiving portion 400 is formed in the piston sleeve 40 for the traction elastic member 42 to pass through the piston sleeve 40, and the other end of the traction elastic member 42 is detachably disposed. In the embodiment of the present invention, in the embodiment of the present invention, a first latch 23 is inserted transversely into the chamber 21 from the outside of the inner tube 2, so that the other end of the traction elastic member 42 can be It is hooked on the first plug 23 to be positioned. Furthermore, after the piston sleeve 40 is placed in the chamber 21 of the inner tube 2, the inner tube 2 and the piston sleeve 40 can be penetrated from the outside of the inner tube 2 to the inside of the inner tube 2, so that the sleeve can be made. 40 can be fixed in the chamber 21. [0013] The receiving portion 400 is formed with an annular involute guiding slope 401 at the end of the piston sleeve 40, and a ring neck portion 402 is further disposed at the proximal end of the piston sleeve 40. The piston washer 41 is provided. That is, it is sleeved on the ring neck 402, and a ring flange 403 is arranged at the end of the ring neck 402 to prevent the ring neck 402 from falling off. The front end of the traction block 43 is not only pulled to the end of the traction elastic member 42 but also has a contact with the guide bevel 401 of the piston sleeve 40. The number of the product is numbered A0101, page 7 / total 20 pages 1013029127-0

M426018_L Modified the replacement page guide surface 430 on January 20, 101, and the rear end of the traction block 43 is detachably attached to the external tube 1 by a second pin 11 laterally extending from the outside of the outer tube 1 of the gun. The ground is fixed, and a sealing gasket 431 is disposed between the gaps fixed to each other. In addition, the outer ring of the piston washer 41 has an involute sealing surface 410, and the piston washer 41 forms an inwardly recessed annular groove 413 on the involute side, so that the piston washer 41 A protruding elastic portion 412 is formed on the outer edge of the involute side, whereby the piston washer 41 is brought into close contact with the inner wall of the air chamber 10 of the outer tube 1 by the elastic portion 412. [0014] Therefore, by the above-mentioned structural composition, the structure of the robbing machine can be obtained. [0015] Accordingly, as shown in the fourth figure, when a gas (as indicated by an arrow) enters the intake port 22, the gas is first dispersed to the front and rear sides of the inner tube 2 of the barrel at the same time, and a part of the forward direction is now forward. In addition to entering the air outlet 20 from the air holes 300 of the air valve 3, the gas will also push the air valve 3 to block the air outlet 20, as shown in the fifth figure; after that, as shown in the sixth figure, all the other gases The gas will be filled in the chamber 21 of the inner tube 2, and the traction block 43 will be moved backward by more gas. At this time, the relative external displacement of the outer tube 1 and the inner tube 2 will be caused. The two elastic members 42 pull each other and can make a close contact with the outer tube 1 of the gun through the piston washer 41, so that the gas amount can be more effectively utilized to provide the recoil force generated by the toy after the firing, etc. Avoid unnecessary gas becoming a waste. However, since the traction elastic member 42 is prone to fatigue fatigue due to long-term gas-driven stretching and its natural recovery, the present invention utilizes the first and second pins 23, 11 to provide the traction elastic member 42 quickly. Replacement, for the user to replace the traction elastic element 42 to maintain its elasticity, and also avoid fatigue
