Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0033] The gunpowder mechanism includes a sliding valve. When maintaining the gunpowder mechanism, it is necessary to remove the gunpowder mechanism, check the air tightness of the life-saving ejection command system, and take out the sliding valve on the gunpowder mechanism. Then take out the gunpowder in the gunpowder mechanism and replace it with new gunpowder. After the gunpowder is replaced, the sliding valve is reinstalled. Grooves are provided at both ends of the sliding valve, and a pit is also provided on the sliding valve at the eccentric position corresponding to the groove. The pit is connected to the groove. A positioning groove is also provided at the bottom of the sliding valve. The positioning groove can facilitate the adjustment of the position of the sliding valve by the tool.

[0034] like Figure 1 , 2 As shown,

[0035] The maintenance tool includes a main body 100 of a columnar structure and a support member 200 arranged on the main body 100. In the present embodiment, the main body 100 is a rectangular parallelepiped structure, the main body 100 is 90 mm long, 22 mm wide and 30 mm high. When the main body 100 is placed horizontally, the support member 200 is vertically fixed on the upper surface of the main body 100. A first guide rod 300 is horizontally arranged on the support member 200 along the axial direction of the main body 100. The first guide rod 300 is a columnar structure. A cylindrical first boss 301 is also arranged at one end of the first guide rod 300 away from the support member 200. The first boss 301 is located at a position deviated from the center of the first guide rod 300. The upper surface of the first boss 301 is located on the same horizontal line as the upper surface of the first guide rod 300. In the present embodiment, the diameter of the first guide rod 300 is 10 mm and the length is 35 mm; the diameter of the first boss 301 is 6 mm and the length is 5 mm.

[0036] That is, when installing the slide valve, align the end of the first guide rod 300 with the end of the slide valve and then insert the first guide rod 300 into the groove at the end of the slide valve, so that the slide valve can be pushed into the gunpowder mechanism through the first guide rod 300, and the first protrusion 301 at the end of the first guide rod 300 is located in the pit on the slide valve, so that the slide valve can be prevented from rotating during the process of pushing the slide valve to move. After pushing the slide groove from one end of the gunpowder mechanism, inserting the guide rod from the other side of the gunpowder mechanism and pushing it several times can make the slide valve close to the middle of the gunpowder mechanism and will not deviate too much from the center of the gunpowder mechanism.

[0037] A second guide rod 400 is also horizontally disposed on the support member 200. The second guide rod 400 is a columnar structure. A second convex column 401 of a columnar structure is disposed at the outer end of the second guide rod 400. A pin 402 of a columnar structure is disposed at the outer end of the second convex column 401. The pin 402 is coaxially disposed with the second convex column 401 and the second guide rod 400. In this embodiment, the diameter of the second guide rod 400 is 10 mm, and the total length of the second guide rod 400 and the second convex column 401 is 22 mm.

[0038] That is, after the sliding valve is inserted into the gunpowder mechanism, the second guide rod 400 is inserted into the gunpowder mechanism from the bottom of the gunpowder mechanism, that is, the clamping pin 402 at the end of the second guide rod 400 can be inserted into the positioning groove at the bottom of the sliding valve, so that the position of the sliding valve can be further adjusted, and then the sliding valve can be accurately located in the middle position of the gunpowder mechanism, thereby facilitating the subsequent installation and fixation of the positioning pin and the shear pin.

[0039] like Figure 1 As shown,

[0040] A U-shaped groove 101 is also provided on the upper surface of the main body 100 corresponding to the first clamping rod. The U-shaped groove 101 is located at one end of the main body 100 close to the first protrusion 301. The right-angled side of the U-shaped groove 101 coincides with the end of the main body 100. The center point of the right-angled side of the U-shaped groove 101 is located at the same position as the center point of the end of the main body 100. In this embodiment, the right-angled side of the U-shaped groove 101 is 18 mm long, the thickness of the U-shaped groove 101 is 3 mm, and the distance from the vertex of the arc edge of the U-shaped groove 101 to the right-angled side is 22 mm.

[0041] The U-shaped groove 101 can pre-limit the position of the sliding valve, that is, when the sliding valve is inserted into the gunpowder mechanism, the first guide rod 300 will move the sliding valve, and when the sliding valve moves to near the middle of the gunpowder mechanism, the U-shaped groove 101 can abut against the bottom of the gunpowder mechanism, thereby preventing the sliding valve from deviating too much from the predetermined position, thereby facilitating the subsequent adjustment of the sliding valve position by the clamping pin 402.

[0042] like Figure 1 , 2 As shown,

[0043] The support member 200 includes a connecting piece 201 vertically fixed on the upper surface of the main member 100, the bottom center line of the connecting piece 201 coincides with the center line of the upper surface of the main member 100, a support block 202 is provided on the top of the connecting piece 201, the support block 202 is a square structure, the ends of the first guide rod 300 and the second guide rod 400 are connected to the support block 202, that is, the connecting piece 201 is fixed on the main member 100, and the connecting piece 201 provides support for the support block 202, so that the support block 202 can provide support for the first guide rod 300 and the second guide rod 400.

[0044] like Figure 1 ,2 As shown,

[0045] The main body 100 is also provided with two clips 102 corresponding to the connecting piece 201, and the connecting piece 201 is fixed between the two clips 102 by bolts, that is, the connecting piece 201 and the two clips 102 are both provided with through holes, and then the bolts are inserted into the through holes and the nuts are screwed onto the bolts to complete the fixing of the connecting piece 201, and then the support member 200 is fixed to the main body 100;

[0046] Furthermore, the support member 200 can be easily disassembled from the main member 100 by means of bolts, so that the support member 200, the first guide rod 300 and the second guide rod 400 can be easily replaced or maintained.

[0047] like Figure 1 , 2 As shown,

[0048] The first guide rod 300 and the second guide rod 400 are located on the same axis, which can make the combined tool more aesthetically pleasing and facilitate the collection and placement of the tools.

[0049] As shown in 1, 2, and 3,

[0050] The upper surface of the support block 202 is symmetrically provided with a first clamping plate 500 and a second clamping plate 502. One side of the first clamping plate 500 or the second clamping plate 502 is located at the same horizontal plane as one side of the support block 202. A first clamping groove 501 is penetrated through the first clamping plate 500. The axis of the first clamping groove 501 is perpendicular to the axis of the first guide rod 300. In this embodiment, the depth of the first clamping groove 501 is 1.4 mm, that is, the first clamping groove 501 can detect the protrusion of the firing pin in the gunpowder mechanism. When detecting it, align the first clamping groove 501 with the firing pin and then insert it. If the first clamping plate 500 contacts the gunpowder mechanism, it means that the protrusion length of the firing pin is less than 1.4 mm, which is unqualified.

[0051] A second slot 503 is provided on the second clamping plate 502, and the axis of the second slot 503 is perpendicular to the axis of the first guide rod 300. In the present embodiment, the depth of the second slot 503 is 1.7 mm, that is, the second slot 503 can detect the protruding amount of the firing pin in the gunpowder mechanism. When detecting it, the second slot 503 is aligned with the firing pin and then inserted. If the second clamping plate 502 does not contact the gunpowder mechanism, it means that the protruding length of the firing pin is higher than 1.7 mm, which is unqualified.

[0052] The quality of the protruding length of the striker should be controlled between 1.4 mm and 1.7 mm. If it is not within this numerical range, it is unqualified. That is, the protruding length of the striker can be quality tested by the first card slot 501 and the second card slot 503 on the first card plate 500 and the second card plate 502.

[0053] like Figure 3 As shown,

[0054] The bottom of the main body 100 is also provided with a plurality of fixing blocks 600, each of which is provided with a notch 601, which is used to remove the bolts.

The thickness of the fixing block 600 is 15mm, the width is 22mm, and the length is 30mm.

[0055] That is, the two bolts of different sizes on the gunpowder mechanism can be installed or removed through the notch 601 provided on the block, thereby eliminating the need to rely on other tools such as wrenches.

[0056] like Figure 1 , 2 As shown,

[0057] The main body 100 is also provided with gas connectors 700 at both ends, and corresponding to the gas connectors 700, an air channel 701 is provided in the main body 100, and both ends of the air channel 701 are connected to the two gas connectors 700. In this embodiment, the air channel 701 is transversely penetrated on the main body 100, and the diameters of the air holes of the gas connector 700 and the air channel 701 are both 8 mm;

[0058] That is, when the gunpowder mechanism is maintained, the gunpowder mechanism can be disassembled, and then the tool is placed in the original position of the gunpowder mechanism, that is, the gas connectors 700 at both ends of the main body 100 are connected to the gas pipe of the life-saving ejection command system, so as to control the operation of the life-saving ejection command system to avoid the start of the gunpowder mechanism, and also to achieve the effect of detecting the airtightness inspection of the life-saving ejection command system and the function test of the life-saving ejection system.

[0059] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
