[0031] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0032] Please refer to Figure 1 and Figure 2 , now a subway air conditioner air outlet quick disassembly tool provided by the utility model will be described. A subway air conditioner air outlet quick disassembly tool, including extension rod 1, electric screwdriver 2, pry plate 3 and jacking plate 4. Among them, electric screwdriver 2 is arranged on extension rod 1 along the axial direction of extension rod 1. Pry plate 3 is fixedly arranged at the top end of extension rod 1 and is used for transversely inserting into the gap between the air outlet frame and the carriage. Jacking plate 4 is fixedly arranged at the top end of extension rod 1 and is used for jacking on the lower surface of the air outlet frame. When jacking plate 4 abuts against the lower surface of the air outlet frame, the head of electric screwdriver 2 can be extended from the top end of extension rod 1 to make the head screw the screw on the air outlet frame.

[0033] Specifically, when disassembling the air conditioner air outlet frame, the staff holds extension rod 1 and can directly move electric screwdriver 2, pry plate 3 and jacking plate 4 to the vicinity of the air outlet frame without holding the arm high. Before disassembling the screw, jacking plate 4 is jacked on the lower surface of the air outlet frame to provide stable support for the air outlet frame. At this time, the staff slides electric screwdriver 2 along the axial direction of extension rod 1, so that the head of electric screwdriver 2 is extended from the top end of extension rod 1 and is inserted on the screw, and then electric screwdriver 2 is started to screw the screw down. When it is needed to pry the air outlet frame from the top of the carriage, the staff inserts pry plate 3 transversely into the gap between the air outlet frame and the carriage, uses extension rod 1 as a lever and exerts a small force to generate a large prying force, so that the air outlet frame can be easily disassembled.

[0034] In some examples, please refer to Figure 1 and Figure 3 , the head has magnetism for adsorbing the screw, the top end of extension rod 1 is hinged with push plate 51, and extension rod 1 is provided with elastic member for pushing push plate 51 to rotate. When the elastic member is in the natural state, push plate 51 blocks the moving path of the head. When the head is extended, push plate 51 is pushed to rotate and avoids the head. When the head adsorbs the screw and is retracted, push plate 51 rotates and pushes the screw away from the head.

[0035] When the electric screwdriver 2 screws down the screw, the bit can automatically adsorb the screw to prevent the screw from falling and losing. When the bit extends to screw the screw, the push plate 51 is pushed by the bit to rotate and avoid the bit, which does not affect the normal extension of the bit. When the bit adsorbs the screw to retract, the push plate 51 can be tightly attached to the bit under the action of the elastic member, so that the bit retracts to push the screw off the bit, so that the worker does not need to manually remove the screw, reduces the operation steps and hand movements, and improves the work efficiency.

[0036] In some embodiments, referring to Figure 3 , the elastic member is a spring sheet 52, one end of the spring sheet 52 is fixed with the extension rod 1, and the other end is abutted against the push plate 51. The spring sheet 52 has the advantages of simple structure, low cost and stable elasticity. During the entire working process, it can continuously provide a stable elastic pushing force for the push plate 51, ensuring the reliability of the cooperative action between the push plate 51 and the bit, and improving the stability and durability of the entire quick release tool.

[0037] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the top end of the extension rod 1 is detachably connected with a storage box 6 for collecting the screw, and the free end of the push plate 51 faces the storage box 6, so that when the push plate 51 pushes the screw away from the bit, the screw can fall into the storage box 6.

[0038] When the push plate 51 pushes the screw away from the bit, the screw falls into the storage box 6, thereby avoiding the scattering of the screw in the vehicle compartment, and facilitating the staff to collect the screw. After completing the disassembly work of multiple air outlet frames, the staff only needs to take down the storage box 6 to easily obtain all the disassembled screws, without the need to search for the screws one by one at the top of the vehicle compartment or other places, greatly improving the work efficiency, and also reducing the safety hazards and equipment failure risks caused by the loss or omission of the screw.

[0039] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the storage box 6 is fixedly provided with a plug-in part 61, and the extension rod 1 is fixedly provided with a connecting part 11, and the connecting part 11 is provided with a plug groove 111 suitable for the plug-in part 61 to plug in along the axial direction of the extension rod 1, and the top end of the plug groove 111 is open and the bottom end is closed. Specifically, the cross section of the plug-in part 61 is isosceles trapezoidal, and the shape of the plug groove 111 is adapted to the isosceles trapezoidal.

[0040] When installing the storage box 6, it is only necessary to vertically insert the plug-in part 61 into the insertion slot 111, which is convenient to operate and does not require complex tools or additional fixing steps. Moreover, when the plug-in part 61 is plugged into the insertion slot 111, the bottom end of the plug-in part 61 abuts against the bottom end of the insertion slot 111, thereby supporting the plug-in part 61 and effectively positioning and supporting the storage box 6 in the vertical direction.

[0041] In some embodiments, referring to Figure 3 , the connecting part 11 is provided with a positioning slot 112 on the side facing the plug-in part 61, and the plug-in part 61 is provided with a positioning piece having an elastic freedom of movement towards the connecting part 11, so that when the plug-in part 61 is plugged into the insertion slot 111, the positioning piece is clamped in the positioning slot 112. The positioning slot 112 on the connecting part 11 is connected with the positioning piece on the plug-in part 61, thereby reinforcing the storage box 6 and preventing it from falling off the extension rod 1 during use.

[0042] In some embodiments, referring to Figure 3 , the positioning piece includes a positioning bead 71 and a spring 72. The positioning bead 71 is slidingly arranged on the plug-in part 61. The spring 72 is fixedly arranged between the positioning bead 71 and the plug-in part 61 and is used to push the positioning bead 71 to move towards the connecting part 11.

[0043] The positioning bead 71 can be clamped into the positioning slot 112 under the action of the spring 72, thereby achieving a tight connection between the storage box 6 and the extension rod 1. The elastic force of the spring 72 can always maintain a tight contact between the positioning bead 71 and the positioning slot 112, thereby preventing the connection from loosening during use and improving the reliability and durability of the entire connecting structure, thereby ensuring the stable operation of the storage box 6 in the quick-release tool and providing a reliable guarantee for the collection of screws. At the same time, when it is necessary to disassemble the storage box 6, it is only necessary to exert an external force to overcome the elastic force of the spring 72, so that the positioning bead 71 is separated from the positioning slot 112, and the storage box 6 can be easily removed, which is simple and convenient to operate and improves the convenience and flexibility of the installation and disassembly of the storage box 6.

[0044] In some embodiments, referring to Figure 4 , the inner bottom surface of the storage box 6 is fixedly provided with a magnet 62 for adsorbing screws, and the upper surface of the magnet 62 is fixedly provided with a rubber pad 63.

[0045] The adsorption of the magnet 62 can ensure that the screws are always fixed in the storage box 6, thereby facilitating the quick finding and taking of the screws by the staff when needed. At the same time, the rubber pad 63 on the upper surface of the magnet 62 plays a role in protecting the screws and the magnet 62. When the screws fall into the storage box 6 and are adsorbed by the magnet 62, the rubber pad 63 can buffer the impact between the screws and the magnet 62, thereby ensuring the integrity and reusability of the screws.

[0046] In some embodiments, referring to Figure 1 and Figure 2 , the bottom end of the electric screwdriver 2 is fixedly provided with a connecting rod 21, the connecting rod 21 extends along the axial direction of the extension rod 1 and penetrates the extension rod 1 downward, and the bottom end of the connecting rod 21 is fixedly provided with a handle 22.

[0047] The staff can hold the handle 22 and operate the lifting and rotation of the electric screwdriver 2 by controlling the handle 22. The handle 22 can enable the staff to maintain a natural and comfortable hand posture during operation, reducing hand fatigue. The comfortable and convenient operation control function can significantly improve the work experience and work efficiency of the staff.

[0048] In some embodiments, referring to Figure 1 and Figure 2 , the handle 22 is fixedly provided with a switch 23 electrically connected with the electric screwdriver 2, so that the staff can conveniently control the start and stop of the electric screwdriver 2. During operation, the staff only needs to press the switch 23 with the fingers to realize the operation of the electric screwdriver 2, reducing the operation time. At the same time, the position of the switch 23 is arranged on the handle 22, which is convenient for the staff to operate while holding the handle 22, conforms to the human operation habit, and further improves the convenience and comfort of the operation.

[0049] In summary, compared with the prior art, the subway air conditioner air outlet quick disassembly tool provided by the utility model enables the staff to hold the appropriate position of the extension rod 1 during disassembly of the subway air conditioner air outlet frame, without the need to hold the arm high to perform the operation.
