The side wall of the lever is provided with a long strip-shaped sliding hole along the length direction of the lever, and the rotating shaft penetrates through the long strip-shaped sliding hole and is matched with the long strip-shaped sliding hole;

still be equipped with the proportion control assembly in the lever, the proportion control assembly includes screw rod and a pair of nut, the screw rod sets up along the length direction of lever, and its both ends difference fixed connection is on two fixed blocks, the screw rod is worn to establish the pivot, it is a pair of the nut all cup joints screw rod, and pass through threaded connection with the screw rod, it is a pair of the nut supports the both sides at the pivot respectively.

A through hole is formed in the rotating shaft, the screw rod penetrates through the through hole, and the inner diameter of the through hole is larger than the outer diameter of the screw rod and is coaxial with the screw rod.

The utility model discloses can overlap the pole portion at ground nail with the U-shaped draw-in groove during the use to make the head of ground nail be in within the nail nipping piece, afterwards, push down the handle and can hang gradually, extract the ground nail. In the process, due to the existence of the lever, the labor intensity of operators is greatly reduced, and the operators can stably and efficiently take out the ground nail. The present case has structure exquisiteness, convenient operation, excellent in use effect and low in labor intensity etc. advantage on the whole.

Detailed Description

The utility model is shown in fig. 1-6, and comprises a stand column 1, a lever 2, a handle 3, a steel wire rope 4 and a nail nipping block 5, wherein the middle part of the lever 2 is hinged on the top end of the stand column 1, the handle 3 is fixedly connected with one end of the lever 2, the steel wire rope 4 is fixedly connected with the other end of the lever 2, and the distance between the handle 3 and the stand column 1 is larger than the distance between the steel wire rope 4 and the stand column 1;

as shown in fig. 4-6, the nail nipping block 5 is C-shaped, the top edge of the nail nipping block 5 is fixedly connected to the bottom end of the steel wire rope, and a U-shaped slot 50 is formed in the bottom edge of the nail nipping block 5. When in use, the U-shaped clamping groove can be sleeved on the rod part of the ground nail, the head part of the ground nail is positioned in the nail pulling block, and then the handle is pressed downwards to gradually lift and pull out the ground nail. In the process, due to the existence of the lever, the labor intensity of operators is greatly reduced, and the operators can stably and efficiently take out the ground nail. The present case has structure exquisiteness, convenient operation, excellent in use effect and low in labor intensity etc. advantage on the whole.

The lever 2 is made of C-shaped steel, a through groove is formed in the top end of the upright column, the lever 2 is hinged in the through groove through a rotating shaft 22, two fixing blocks 21 located in the lever are arranged at two ends of the lever 2 respectively, the two fixing blocks 21 are fixedly connected with the inner side surface of the lever 2, and the handle 3 is fixedly connected to the fixing blocks far away from the position where the steel wire rope is located.

The side wall of the lever 2 is provided with a strip-shaped sliding hole 20 along the length direction, and the rotating shaft 22 is arranged in the strip-shaped sliding hole 20 in a penetrating manner and is matched with the strip-shaped sliding hole 20;

still be equipped with the proportion control assembly in the lever 2, the proportion control assembly includes screw rod 23 and a pair of nut 24, screw rod 23 sets up along the length direction of lever 2, and its both ends difference fixed connection is on two fixed blocks 21, screw rod 23 wears to establish pivot 22, it is a pair of nut 24 all cup joints screw rod 23, and pass through threaded connection, a pair of with screw rod 23 nut 24 supports the both sides at pivot 22 respectively. Therefore, the lever can do linear motion relative to the rotating shaft by loosening the pair of nuts, so that the length of the lever on two sides of the rotating shaft can be freely adjusted according to the space limitation of the self requirement and the operating place of the operator, and the labor-saving degree of the lever can be conveniently adjusted. After the adjustment is finished, the operator can rotate the pair of nuts towards the rotating shaft again and tighten the nuts, so that the lever structure is fixed, and the lever has good stability.

A through hole is formed in the rotating shaft, the screw rod penetrates through the through hole, and the inner diameter of the through hole is larger than the outer diameter of the screw rod and is coaxial with the screw rod. Therefore, the rotating shaft is not contacted with the screw rod, and the long strip-shaped sliding hole in the lever is always contacted with the rotating shaft, while the screw rod is not contacted with the rotating shaft; therefore, when an operator nails up, the main force will act on the lever, the screw rod will not be subjected to radial shearing force, but only the axial acting force of the nut acting on the screw rod, so that the service life and the service stability of the screw rod are effectively guaranteed, and the overall service stability and the reliability of the equipment are finally and effectively guaranteed.
