[0046] The transmission mechanism 18 comprises a second piston pipe 181 in communication with the connecting oil pipe 17 and a pushing shaft 184 fixed to the axis of the pawl 242, the inner cavity of the second piston pipe 181 slides a third piston rod 182, one end of the third piston rod 182 is fixed with a moving block 183, the pushing shaft 184 rotates on the surface of the moving block 183, the surface of the moving block 183 slides a sliding shell 185, the sliding shell 185 is fixed to the surface of the fixed plate 5, in the embodiment, through the arrangement of the second piston pipe 181, the third piston rod 182, the moving block 183, the pushing shaft 184 and the sliding shell 185, when the internal pressure of the fixed oil pipe 8 increases, the internal pressure of the second piston pipe 181 can be increased through the connecting oil pipe 17, and then the third piston rod 182 pushes the moving block 183 to move, when the moving block 183 moves, the pushing shaft 184 drives the pawl 242 to work.

[0047] Working principle: during production and processing, the staff can add sealing oil in the fixed oil pipe 8, the connecting oil pipe 17, the second piston pipe 181 and the first piston sleeve 73, and seal them for oil transmission, when the first connecting pipe 1 is quickly installed, the second connecting head 2 and the first connecting head 4 can be used to quickly connect the first connecting pipe 1 and the second connecting pipe 3, the working principle of the second connecting head 2 and the first connecting head 4 is the prior art, which can be referred to the quick mounting head of automobile air conditioner.

[0048] In daily use, when the vehicle is running, if the vehicle passes through complex road surface and shakes, the abutting block 71 can work under the shaking of the second connecting head 2, and then the first piston rod 72 extrudes the sealing oil in the first piston sleeve 73, so that the oil pressure in the inner cavity of the fixed oil pipe 8 is increased, and then the second piston rod 121 slides, and the inclined block 122 fixed on the surface of the second piston rod 121 can be frictionally attached to the stress rod 123, so that the stress rod 123 drives the limiting piece 13 to move towards the first connecting head 4, so that the limiting piece 13 is clamped on the surface of the first connecting head 4, thereby avoiding the disconnection of the second connecting head 2 and the first connecting head 4 when the vehicle shakes.

[0049] After the first piston rod 72 slides in the inner cavity of the first piston sleeve 73, the abutting block 71 can be reset under the action of the telescopic rod 9 and the first spring 10, thereby releasing the oil pressure in the fixed oil pipe 8. Similarly, the second piston rod 121 can be reset under the action of the rebound mechanism 16, the slide rod 14 and the second spring 15, thereby improving the practicability of the device.

[0050] When the oil pressure in the fixed oil pipe 8 is increased, the connecting oil pipe 17 connected with the fixed oil pipe 8 can also deliver the oil pressure to the inner cavity of the second piston pipe 181, thereby moving the third piston rod 182. When the third piston rod 182 moves, the moving block 183 can drive the push shaft 184 to move, and the pawl 242 fixed on the surface of the push shaft 184 can rotate the ratchet wheel 241 in the reciprocating process, and under the action of the stop pawl 245, the ratchet wheel 241 can be prevented from rotating back.

[0051] When the ratchet wheel 241 rotates, the arc gear 232 driven by the connecting shaft 233 rotates the ratchet wheel 241, and then when the arc gear 232 and the stress gear 231 mesh, the stress gear 231 can drive the rotating shaft 19 to rotate, and then the rotating plate 20 is flipped. It is worth noting that the rotating plate 20 is attached to the surface of the ash discharge channel 25 to achieve the effect of sealing the ash discharge channel 25. After the rotating plate 20 rotates and is attached to the surface of the second connecting pipe 3, it has the effect of sealing the second connecting pipe 3. Therefore, the movement of the rotating plate 20 is a fixed angle, that is, it is not sealed to the second connecting pipe 3, but it is sealed to the ash discharge channel 25.

[0052] Under the working condition limit of the rotating plate 20, the number of the ratchet teeth of the ratchet wheel 241 needs to be improved, and the angle of one rotation of the ratchet wheel 241 is limited. In the device, if the vehicle shakes and floats greatly, the third piston rod 182 moves more, and the ratchet wheel 241 can be driven to rotate by the pawl 242. Such movement is a limiting movement, that is, the rotation angle of the ratchet wheel 241 is fixed in one violent shaking. Then the arc gear 232 is rotated. When the arc gear 232 and the force receiving gear 231 are engaged, the teeth on the surface of the arc gear 232 can drive the force receiving gear 231 to move at a specified angle. Through the special limitation of the ratchet wheel 241, the arc gear 232 and the force receiving gear 231, the working requirements of the rotating plate 20 can be met.

[0053] After the rotating plate 20 seals the second connecting pipe 3, since the first connecting pipe 1 continuously supplies air, the dust in the pipeline can be sent out through the dust removal channel 25 to achieve the purpose of dust removal. After the engagement of the arc gear 232 and the force receiving gear 231 is completed, the rotating plate 20 can be reattached to the surface of the dust removal channel 25 under the action of the first shaft spring 22, achieving the sealing effect.
