[0033] Reference Figure 1-5 In a preferred embodiment, a drive block 606 is fixedly installed at the other end of the third rotating shaft 603. A handle 607 is fixedly installed on the side wall of the drive block 606 for driving the third rotating shaft 603 to rotate. A drive ring 608 is slidably installed in the inner cavity of the drive block 606. A limit rod 610 is fixedly installed on the surface of the drive ring 608. A limit hole 611 is opened in the inner cavity of the frame 1. The limit rod 610 is adapted to the limit hole 611 for limiting the third rotating shaft 603.

[0034] Reference Figure 1-5 In a preferred embodiment, a second spring 609 is fixedly installed in the inner cavity of the drive block 606. One end of the second spring 609 is fixedly connected to the drive block 606, and the other end of the second spring 609 is fixedly connected to the drive ring 608.

[0035] In a preferred embodiment, during use, the refrigerant bottle 3 is placed inside the frame 1 and pressed tightly against the side wall of the first positioning frame 602. Then, by rotating the handle 607, the third rotating shaft 603 is driven to rotate clockwise, causing the second positioning frame 605 to abut against the side wall of the refrigerant bottle 3, thus fixing the refrigerant bottle 3. At the same time, the second spring 609 drives the limiting rod 610 to insert into the limiting hole 611, limiting the third rotating shaft 603. When it is necessary to remove the refrigerant bottle 3, the pressure block 613 is pressed to disengage the limiting rod 610 from the limiting hole 611. Then, the third rotating shaft 603 can be rotated counterclockwise, causing the second positioning frame 605 to move away from the refrigerant bottle 3, thus releasing the fixation of the refrigerant bottle 3, and the refrigerant bottle 3 can be removed for convenient use.

[0036] Specifically, the working principle of this refrigerant recovery device for automobile dismantling is as follows: During use, pulling the air pipe 503 drives the take-up roller 502 to rotate counterclockwise, removing the air pipe 503 from the collection chamber 501. Simultaneously, this drives the first rotating shaft 504 to rotate, which in turn drives the second gear 510 and the second rotating shaft 509 to rotate via the third gear 511. This drives the gear ring 506 to rotate the cleaning ring 507, simultaneously cleaning the oil stains on the surface of the air pipe 503. Furthermore, the first spring 516 acts as a catalyst... The drive positioning disk 514 moves towards the first rotating shaft 504, and the second wedge 515 engages and limits the first wedge 513 to prevent the first rotating shaft 504 from rotating clockwise. After use, the pull ring 518 pulls the pull rod 517 to drive the positioning disk 514 to move, so that the second wedge 515 disengages from the first wedge 513. Under the action of the torsion spring 505, the take-up roller 502 can be driven to rotate clockwise, and the air pipe 503 is collected on the surface of the take-up roller 502 for easy use.

[0037] When the refrigerant bottle 3 is placed inside the frame 1, it is pressed tightly against the side wall of the first positioning frame 602. Then, by turning the handle 607, the third rotating shaft 603 is driven to rotate clockwise, causing the second positioning frame 605 to abut against the side wall of the refrigerant bottle 3, thus fixing the refrigerant bottle 3. At the same time, the second spring 609 drives the limiting rod 610 to insert into the limiting hole 611, thus limiting the third rotating shaft 603. When it is necessary to remove the refrigerant bottle 3, the pressure block 613 is pressed to disengage the limiting rod 610 from the limiting hole 611. Then, the third rotating shaft 603 can be rotated counterclockwise, causing the second positioning frame 605 to move away from the refrigerant bottle 3, thus releasing the fixation of the refrigerant bottle 3, and the refrigerant bottle 3 can be removed for convenient use.
