[0004] An existing handheld air-compressed rammer cannot be used by workers of different heights in a comfortable posture. Workers with taller heights need to bend over to use the rammer, which consumes more energy and prevents the workers from using the rammer for a long time.

[0005] Therefore, a handheld air-compressed impact rammer is proposed to address the above problems. Utility Model Content

[0006] In order to solve the problems raised in the above background technology, the utility model provides a handheld air-compressed rammer, which has the advantage of being able to adjust the height of the rammer so that the staff can use the rammer in a comfortable posture.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hand-held air-compressed rammer, comprising an impact plate, a rammer body is fixedly connected to the top of the impact plate, an air-compressed component is fixedly connected to the top of the rammer body, a working box is fixedly connected to the top of the air-compressed component, a bidirectional threaded rod is rotatably connected to the inside of the working box, a first slide rod and a second slide rod are spirally connected to the outside of the bidirectional threaded rod, a first support is fixedly connected to the top of the second slide rod, a support rod is rotatably connected to the inside of the first support, and a second support is rotatably connected to the outside of the support rod.

Both ends of the light rod are fixedly connected to the inner wall of the working box. Under the action of the light rod, the sliding of the first slide rod and the second slide rod can be made more stable without any deviation.

[0010] Preferably, a groove is opened inside the working box, and a ring block is fixedly connected to the bottom end of the top box, and the cross-sectional area of ​​the groove is the same as the cross-sectional area of ​​the ring block, thereby increasing the contact area between the top box and the working box, making the structure more stable and preventing left and right shaking.

[0011] Preferably, a second spring is fixedly connected to the bottom surface of the groove, and the number of the second springs is symmetrical, two on each side, which can reduce the impact force of the rammer body on the hand and make the staff more comfortable when using the rammer.

When the rammer is finished using, the pull rod can be pulled to separate the block from the ratchet to restore the handle angle. The pull block can save the staff more effort.

[0013] Preferably, the outer side of the handle is provided with an anti-slip cover, and the material of the anti-slip cover is rubber. The anti-slip cover can prevent the staff from slipping when holding the handle, and the rubber material can also appropriately reduce the impact force of the rammer body on the hand.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides an impact plate. When a worker is tall and needs to bend over when using the rammer, the worker rotates the bidirectional threaded rod rotatably connected inside the working box, so that the bidirectional threaded rod drives the first sliding rod and the second sliding rod spirally connected on the outside to slide inside the working box. The first support fixedly connected to the top of the second sliding rod supports the support rod, so that the support rod rotates inside the first support, and the other end of the support rod supports the second support, so that the second support lifts the top box, thereby increasing the height of the rammer. This is convenient for workers with taller heights to hold the rammer in a more comfortable posture without bending over, so as to facilitate long-term work, improve work efficiency, and improve the practicality of the rammer.

[0016] 2. The utility model provides a handle, and when the staff feels uncomfortable holding the handle, the handle can be lifted upward to rotate inside the top box, and drive the ratchet fixedly connected to the outside of the handle to rotate. When the arm feels comfortable, the lifting range is stopped, and the fixed block fixedly connected to the inside of the top box will pull the first spring, and the first spring will pull back the block, so that it is stuck with the ratchet and the position of the handle is fixed, thereby realizing the change of the handle angle, allowing the staff to hold the handle at a more comfortable angle, saving energy and improving work efficiency.

[0030] Working principle and process:

[0031] When the worker is tall and needs to bend over to use the rammer, the worker can shake the hand wheel to drive the two-way threaded rod 5 to rotate inside the working box 4, so that the two-way threaded rod 5 drives the first sliding rod 6 and the second sliding rod 7 spirally connected on the outer side to slide inside the working box 4. Because the light rod 21 runs through the first sliding rod 6 and the second sliding rod 7, under the action of the light rod 21, the first sliding rod 6 and the second sliding rod 7 can slide more stably without deviation. The first support 8 fixedly connected to the top of the second sliding rod 7 will support the support rod 9, so that the support rod 9 rotates inside the first support 8, and the other end of the support rod 9 supports the second support 10, so that the second support 10 lifts the top box 11, so that the annular block 19 slides out of the groove 23, increasing the contact area between the top box 11 and the working box 4, making the structure more stable, and realizing the increase of the height of the rammer, which is convenient for workers with taller heights to hold the rammer in a more comfortable posture without bending over, so as to facilitate long-term work. The present invention relates to a method for making the rammer more convenient to use and improving the working efficiency and the practicality of the rammer. When the staff member feels uncomfortable holding the handle 12, the handle 12 can be lifted upward to rotate the handle 12 inside the top box 11 and drive the ratchet 13 fixedly connected to the outside of the handle 12 to rotate. When the arm feels comfortable, the lifting amplitude is stopped, and the fixed block 16 fixedly connected to the inside of the top box 11 will pull the first spring 15, and the first spring 15 will pull back the block 14, so that it and the ratchet 13 are stuck to each other and the position of the handle 12 is fixed, thereby realizing the change of the angle of the handle 12, allowing the staff member to hold the handle 12 at a more comfortable angle, saving energy and improving working efficiency. The anti-slip sleeve 22 arranged on the outside of the handle 12 can prevent the staff member from slipping when holding the handle 12, and the rubber material can also appropriately reduce the impact force of the rammer body 2 on the hand. When the rammer is finished, the pull rod 18 can be pulled to separate the block 14 from the ratchet 13 to restore the angle of the handle 12.
