[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] This specific embodiment is a pneumatic wrench pump, and its structural diagram is as follows Figure 1 As shown, it includes a pump body 1 and a support assembly 2. The support assembly 2 is symmetrically distributed on both sides of the pump body 1.

[0024] Reference Figure 2 、 Figure 3 The support assembly 2 includes a mounting block 9 and a lifting rod 10. The mounting blocks 9 are symmetrically arranged on both sides of the lifting rod 10 and are slidably connected to the mounting block 9. Rotating rods 3 are spaced apart above the lifting rod 10. The two ends of the rotating rod 3 rotate and penetrate the interior of the mounting block 9, which has a hollow interior. A clamping head 15 is elastically mounted on the end of the lifting rod 10 that penetrates the interior of the mounting block 9. A movable plate 14 is provided on the inside of the mounting block 9. The movable plate 14 is arranged vertically and has a clamping hole 12 on its surface. The clamping hole 12 is adapted to engage with the clamping head 15. Multiple groups of support blocks 5 are arranged in an array on the bottom end surface of the lifting rod 10. The bottom of the support block 5 has a bottom block 6, and the bottom of the mounting block 9 has a movable wheel 7. A grip 4 is located in the center of the rotating rod 3. Screws 11 are fixedly connected to each end of the rotating rod 3. The screw 11 is rotatably mounted inside the mounting block 9. The external thread of the screw 11 is provided with a movable block 18. The two ends of the movable block 18 slide against the inner wall of the mounting block 9. The movable plate 14 is vertically mounted on the bottom of the movable block 18 and is fixedly connected to the movable block 18. A lifting slot 8 is vertically defined on the surface of the mounting block 9 facing the lifting rod 10. A first spring 13 is fixed below the end of the lifting rod 10 that passes through the lifting slot 8. The first spring 13 is vertically mounted, with the end away from the lifting rod 10 fixedly connected to the bottom surface of the mounting block 9.

[0025] Reference Figure 4The end of the lifting rod 10 has a slide groove 17, and the clamping head 15 slides horizontally inside the slide groove 17. The end of the clamping head 15 that penetrates into the slide groove 17 is fixedly connected to the second spring 16, and the end of the second spring 16 away from the clamping head 15 is fixedly connected to the inner wall of the slide groove 17.

[0026] Working principle: when in use, the pump body 1 is moved by the support assembly 2, and a moving wheel 7 is provided at the bottom of the mounting block 9 for the pump body 1 to move. When the pump body 1 needs to be used, the pump body 1 can be pulled up and the lifting rod 10 is stepped down. When the pump body 1 is pulled up, the moving wheel 7 at its bottom leaves the ground, and when the lifting rod 10 is forced to drop, the first spring 13 is compressed, and the lifting rod 10 but the clamping head 15 also slides against the surface of the moving plate 14 until the clamping mouth slides to the position of the corresponding clamping hole 12, the second spring 16 is forced to pop out, and the clamping head 15 is clamped with the clamping hole 12. At this time, the lifting rod 10 of the lowered height is limited and fixed, and then the pulled-up pump body 1 is released, and the pump body 1 is supported by the bottom block 6 and the support block 5. The moving wheel 7 is in a suspended state at this time, which can better improve the operating stability of the main body. The support assemblies 2 on both sides of the pump body 1 need to be operated and unfolded alternately;

[0027] When the pump body 1 needs to be moved, the grip rod 4 can be rotated, and the grip rod 4 drives the rod to be installed to rotate, and the screw 11 at the end of the rotating rod 3 is forced to rotate, and the moving block 18 threadedly connected to the screw 11 slides, driving the moving plate 14 to move synchronously, and the moving plate 14 slides in the direction away from the lifting rod 10 until the clamping head 15 exits the clamping hole 12, and then the first spring 13 is reset, pushing the lifting rod 10 up, at this time the bottom block 6 can leave the ground, and the pump body 1 is supported by the moving wheel 7 for easy movement, and then the rotating rod 3 is rotated in the opposite direction to drive the moving plate 14 to move closer to the end of the lifting rod 10.
