detailed description

Below in conjunction with accompanying drawing the embodiment of the present utility model is further described:

As shown in Figures 1-7, a convenient nail pulling machine with no damage to the surface and labor-saving, including an outer cylinder 2, an inner cylinder 8, a clamping cone 9, a base 6, a lever 3, a return spring 7, two clamping The cones 9 are combined into a cone structure, the inner cylinder 8 is set on the outside of the clamping cone 9, the inner wall of the inner cylinder 8 matches the taper of the clamping cone 9, and the dovetail groove guide rail 91 and the dovetail groove 81 are passed between the two. Mating connection, the outside of clamping cone 9 bottom is provided with square slotted hole 92, is provided with clamping notch 93 in the middle of clamping cone 9 bottoms, and one end of lever 3 is arranged in square slotted hole 92, lever lever The fulcrum of 3 is hinged with the lever bracket 5 through the pin shaft 4, the lever bracket 5 is fixed on the base 6, the outer cylinder 2 is set on the outside of the inner cylinder 8, the bottom of the outer cylinder 2 is fixedly connected with the base 6, and the return spring 7 is set on the On the top of the inner cylinder 8 , one end of the return spring 7 abuts against the outer cylinder 2 , and the other end abuts against the shoulder of the inner cylinder 8 .

Both sides of the bottom of the outer cylinder 2 are provided with openings, and two levers 3 extend into the square slots 92 of the clamping cone 9 from the opening at the bottom of the outer cylinder 2 .

The outer diameter of the inner cylinder 8 is set to three levels, which are thickened step by step from top to bottom, and a shoulder is formed between the diameters of adjacent two levels. The inner cylinder 8 protrudes from the upper end of the outer cylinder 2, and the upper end of the inner cylinder 8 A handle 1 is fixed, and a dovetail groove 81 is provided on the tapered inner wall of the inner tube 8 . Both sides of the inner cylinder 8 are also provided with openings for placing the lever 3 .

A dovetail guide rail 91 is provided on the tapered outer wall of the clamping cone 9 .

The dovetail groove guide rail 91 and the dovetail groove 81 are in clearance and slide relative to each other. When the inner cylinder 8 slides upward along the cone, the two clamping cones 9 will be caught by the dovetail groove as the outer diameter of the inner wall of the inner cylinder 8 increases. The guide rail 91 and the dovetail groove 81 are driven to separate to the two sides. When the inner cylinder 8 slides down along the cone, as the outer diameter of the inner wall of the inner cylinder 8 decreases, the two clamping cones 9 will be clamped in the middle under the push of the inner cylinder 8 .

As shown in Fig. 5, a clamping notch 93 is provided in the middle of the clamping cone 9, which is convenient for clamping the nail and fastening the nail cap so that it is not easy to fall off. The two edges of the clamping slot 93 form an angle of 150°, which is suitable for clamping nails of various diameters.

See Fig. 4, Fig. 6, Fig. 7, the cylinder 31 is fixed on one end of the lever 3 arranged in the square slot 92 at the bottom of the clamping cone 9. The cylinder 31 matches the size of the square slot 92 , and the clamping cone 9 and the cylinder 31 can slide relative to each other in the horizontal direction, so as to realize the separation and clamping of the two clamping cones 9 . The cylinder 31 can also pry up the clamping cone 9 in the vertical direction, so as to realize the upward and downward linkage between the clamping cone 9 and the lever 3 .

See Figure 8 and Figure 9, a nail pulling method using a convenient nail pulling machine with no damage to the surface, and the specific method is as follows:

1) Hold the lever 3 and the base 6 by hand, control the clamping cone 9 through the lever 3 so that it will not move axially with the inner cylinder 8, pull the handle 1 upwards, and the inner cylinder 8 will slide upwards accordingly, and the dovetail Under the cooperative action of the groove guide rail 91 and the dovetail groove 81, the two clamping cones 9 are opened to both sides.

2) Attach the base 6 of the nail pulling machine to the wall or wooden material, and place the nail cap and the protruding part of the nail in the clamping notch 93 opened by the clamping cone 9 .

3) The handle 1 is released, and under the action of the return spring 7, the inner tube 8 and the two clamping cones 9 are reset, and the reset two clamping cones 9 clamp the nail and buckle the nail cap.

4) Press down the lever 3 on both sides, the cylinder 31 at the bottom of the lever 3 pries the two clamping cones 9 to move upward, and at the same time, the clamping cone 9 pushes the inner cylinder 8 to move upward together, compresses the return spring 7, and pulls up nail.

5) Lift up the levers 3 on both sides. At this time, the clamping force of the clamping cones 9 on both sides is weakened, and the cylinder 31 at the bottom of the lever 3 will drive the clamping cones 9 to move downward. At the same time, under the action of the return spring 7 , the inner cylinder 8 also moves downwards, returning to the clamping state described in step 3).

6) Repeat the action of step 4), and repeat the action of pulling out the nail until the nail is pulled out.
