[0027] Reference Figure 1-2The utility model provides an embodiment: a retractable pneumatic tractor, comprising a tractor body 1, the upper bottom of the tractor body 1 is connected to a pneumatic source body 2, the bottom of the pneumatic source body 2 is installed with a pneumatic connector 3, the outer wall of the pneumatic source body 2 is installed with a pneumatic control switch 5, the rear end of the tractor body 1 is connected to a rear end connection end 4, the front end of the tractor body 1 is installed with a front end connection end 6, one end of the front end connection end 6 is connected to a fixed sleeve 7, one end of the fixed sleeve 7 is connected to a telescopic sleeve 8, a screw 9 is arranged inside the telescopic sleeve 8, a limiting slide groove 10 is arranged on the outer wall of the telescopic sleeve 8, and a pin hole 11 is arranged on the outer wall of the fixed sleeve 7.

[0028] Specifically, the screw rod 9 is connected to the pneumatic structure, and the screw rod 9 is threadedly connected to the inside of the telescopic sleeve 8. The telescopic sleeve 8 can be limited by the setting of the limiting slide groove 10 and the pin hole 11. During installation, the pin is inserted into the inside of the pin hole 11, and then connected to the limiting slide groove 10 for limiting, so that the telescopic sleeve 8 will not rotate under the drive of the screw rod 9, but will only move forward and backward along the fixed sleeve 7, thereby realizing the function of traction and telescoping.

[0029] In the present invention, the pneumatic source body 2 is fixedly connected to the bottom of the tractor body 1 , and the size of the pneumatic source body 2 is smaller than the size of the tractor body 1 .

[0030] Furthermore, the pneumatic control switch 5 is rotatably connected to the connection between the tractor body 1 and the pneumatic source body 2, the pneumatic connector 3 is fixedly connected to the bottom of the pneumatic source body 2, and the other end of the pneumatic connector 3 is connected to the air pump to realize the air supply to the pneumatic source body 2. In addition, the rotatable connection design of the pneumatic control switch 5 enables its position to be flexibly adjusted, which is convenient for user operation.

[0031] Furthermore, the rear end connection end 4 is integrally connected to one end of the tractor body 1, and the front end connection end 6 is integrally connected to the other end of the tractor body 1. The rear end connection end 4 has the same size as the front end connection end 6. By setting the rear end connection end 4 and the front end connection end 6, both ends of the device can be connected to external devices.

[0032] Furthermore, the fixed sleeve 7 is fixedly installed at one end of the front connecting end 6, threads are provided on the outer walls at both ends of the fixed sleeve 7, the telescopic sleeve 8 is movably connected inside the fixed sleeve 7, and the size of the fixed sleeve 7 is larger than that of the telescopic sleeve 8.

[0033] Furthermore, the screw rod 9 is movably connected to the inside of the telescopic sleeve 8, and the inside of the telescopic sleeve 8 is provided with a thread. The limiting slide groove 10 is provided on the outer wall of the telescopic sleeve 8, and the latch hole 11 is provided on the outer wall of the fixed sleeve 7. There are two latch holes 11. The telescopic sleeve 8 can limit the screw rod 9. The matching design between the fixed sleeve and the telescopic sleeve enables the tractor to adjust its length conveniently when needed. The threads provided on the outer walls at both ends of the fixed sleeve match the threads inside the telescopic sleeve, so that the telescopic sleeve can perform telescopic movement inside the fixed sleeve. At the same time, the setting of the screw rod and the limiting slide groove inside the telescopic sleeve can accurately control the telescopic length of the telescopic sleeve, avoiding excessive stretching or contraction during use.

[0034] Working principle and usage process:

[0035] When the retractable pneumatic tractor is used, first ensure that the air pump is connected to the pneumatic connector 3 to provide the required pneumatic power. Then, by turning the pneumatic control switch 5, the working state of the pneumatic source body 2 can be conveniently controlled, thereby controlling the movement of the screw 9 inside the telescopic sleeve 8.

[0036] In the initial state, the telescopic sleeve 8 may be in a contracted state and fit tightly with the fixed sleeve 7. At this time, by operating the pneumatic control switch 5, the pneumatic source body 2 is started, so that the screw 9 starts to rotate inside the telescopic sleeve 8. Since the screw 9 cooperates with the thread inside the telescopic sleeve 8, and the telescopic sleeve 8 is movably connected inside the fixed sleeve 7, the rotation of the screw 9 will drive the telescopic sleeve 8 to move forward and backward along the fixed sleeve 7.

[0037] During the movement of the telescopic sleeve 8, the movement direction of the telescopic sleeve 8 is effectively controlled due to the arrangement of the limiting slide groove 10 and the latch hole 11. The latch is inserted into the latch hole 11 and cooperates with the limiting slide groove 10 to ensure that the telescopic sleeve 8 can only move linearly along the fixed sleeve 7 without rotation.

[0038] In this way, the pneumatic tractor can realize the telescopic function as needed. When the telescopic sleeve 8 moves forward, the object can be pulled; and when the telescopic sleeve 8 moves backward, the object can be released. This design makes the pneumatic tractor flexible and adjustable, and suitable for a variety of different application scenarios.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
