[0008] Through the above technical solution, when the length of the push-pull rod needs to be adjusted, the slider is pushed upward, the slider drives the connecting rope to slide upward, the connecting rope pulls the lifting block, and the lifting block drives the connecting buckle to rotate, so that the connecting buckle is disengaged from the buckle groove. At this time, the first connecting rod and the second connecting rod are relatively slid, the push-pull rod is adjusted to an appropriate length, and the connecting buckle is buckled into the specified buckle groove, thereby fixing the length of the push-pull rod, which can be adapted to people of different heights.

[0009] Optionally, the handle includes a first connection cover and a second connection cover that are arranged opposite to each other.

[0010] Through the above technical solution, by splitting the handle into the first connecting cover and the second connecting cover, it is convenient to install the slider.

[0011] The beneficial effects of the utility model are as follows: when the length of the push-pull rod needs to be adjusted, the slider is pushed upward, the slider drives the connecting rope to slide upward, the connecting rope pulls the lifting block, and the lifting block drives the connecting buckle to rotate, thereby causing the connecting buckle to disengage from the buckle groove. At this time, the first connecting rod and the second connecting rod are relatively slidable, the push-pull rod is adjusted to an appropriate length, and the connecting buckle is buckled into the specified buckle groove, thereby fixing the length of the push-pull rod, which can be adapted for use by people of different heights.

DETAILED DESCRIPTION

[0015] The following is combined with Figure 1-2 This application is described in further detail.

[0016] The embodiment of the present application discloses an air pump.

[0017] The air pump includes a handle 1, a barrel body 2, a push-pull rod 3 and an air outlet pipe 4. The push-pull rod 3 is slidably arranged in the barrel body 2. The handle 1 is arranged on the rod portion of the push-pull rod 3. The air outlet pipe 4 is arranged on the side wall of the barrel body 2 and is connected to the inside of the barrel body 2. The push-pull rod 3 includes a first connecting rod 31 and a second connecting rod 32. A push block 311 is arranged at one end of the first connecting rod 31. The push block 311 is slidably connected to the barrel body 2. A sliding groove 11 is opened at one end of the first connecting rod 31 away from the push block 311. The second connecting rod 32 is slidably connected to the sliding groove 11. A rotating groove 321 is opened on the side wall of the second connecting rod 32. A rotating rod 3211 is provided, and a connecting buckle 5 is rotatably connected to the rotating rod 3211. A plurality of buckle grooves 3121 for buckling the connecting buckle 5 are provided on the side wall of the first connecting rod 31. A torsion spring 32111 is sleeved on the side wall of the rotating rod 3211. The torsion spring 32111 drives the connecting buckle 5 to rotate in the direction of the buckle groove 3121. A lifting block 51 is provided on the side wall of the connecting buckle 5. A connecting rope 6 is wound around the lifting block 51. A sliding groove 312 is provided on the side of the handle 1 close to the second connecting rod 32. A slider 111 is slidably provided in the sliding groove 312, and the end of the connecting rope 6 away from the lifting block 51 is wound around the slider 111.

[0018] When the length of the push-pull rod 3 needs to be adjusted, the slider 111 is pushed upward, and the slider 111 drives the connecting rope 6 to slide upward. The connecting rope 6 pulls the lifting block 51, and the lifting block 51 drives the connecting buckle 5 to rotate, so that the connecting buckle 5 is disengaged from the buckle groove 3121. At this time, the first connecting rod 31 and the second connecting rod 32 slide relative to each other, and the push-pull rod 3 is adjusted to an adaptive length, so that the connecting buckle 5 is buckled into the designated buckle groove 3121, thereby fixing the length of the push-pull rod 3, which can be adapted to people of different heights.

[0019] The handle 1 includes a first connection cover 12 and a second connection cover 13 which are arranged opposite to each other.

[0020] By splitting the handle 1 into the first connection cover 12 and the second connection cover 13 , it is convenient to install the slider 111 .

[0021] The implementation principle of an air pump in an embodiment of the present application is: when it is necessary to adjust the length of the push-pull rod 3, the slider 111 is pushed upward, the slider 111 drives the connecting rope 6 to slide upward, the connecting rope 6 pulls the lifting block 51, and the lifting block 51 drives the connecting buckle 5 to rotate, thereby causing the connecting buckle 5 to disengage from the buckle groove 3121. At this time, the first connecting rod 31 and the second connecting rod 32 are relatively slidable, the push-pull rod 3 is adjusted to an adaptive length, and the connecting buckle 5 is buckled into the designated buckle groove 3121, thereby fixing the length of the push-pull rod 3, which can be adapted for use by people of different heights.

[0022] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
