specific Embodiment

[0006] Specific embodiment: the power nail puller of the present invention shown in this accompanying drawing has the chuck 4 of band bayonet, and the inner side of the chuck has horns, and along the horns, there is an inverted trapezoidal groove to the middle. The stepped shaft at the upper end of the clamping head and the annular bearing 7 at the lower end of the hollow screw rod are movably socketed, and the upper end of the stepped shaft is fixedly connected with the chuck 8 through a screw 9 to form a flexible connection. The upper end of the hollow screw 2 is statically fitted with a power joint 1 fixed thereto. The hollow screw is fitted with a threaded sleeve 3 for external movement. Like this, the clip head is stuck in the bayonet of the inverted trapezoidal groove by the nail cap on the nail 5 upper end through its horn transition, forming the bayonet inner side to be stuck below the nail cap. The power joint 1 on the screw rod upper end is connected with the rotati...

Abstract

The invention discloses a power nail puller which comprises a chuck with a bayonet, the upper end of the chuck is movably connected with the lower end of a screw, the upper end of the screw is provided with a power joint, the screw is sheathed with a threaded sleeve by movable fit; the bayonet of the cluck is clamped below a nail head, the power joint at the upper end of the screw is connected with a rotational power machine, the rotation of the power machine drives the screw to rotate, the screw relatively rotates and moves upwards opposite to the threaded sleeve to drive the chuck and the nail to move upwards, so the nail is vertically and smoothly pulled out; the lower end surface of the threaded sleeve is a pattern surface or tooth-form surface or corrugated surface, thus increasing the friction force of the wooden materials around the threaded sleeve, and the nail, and the like, and also improving the reliability of pulling out the nail.

Description

Technical field: [0001] The power nail puller is a tool used to pull out the iron nails in the wood, especially the nail puller that is directly and quickly pulled out along the longitudinal direction of the iron nails by power. Background technique: [0002] Existing nail pullers all have a clip with a bayonet that is stuck on the nail cap, and the clip with the bayonet is connected with a driven handle. Drive the handle to drive the bayonet and the nail to move obliquely, so as to pull out the nail; however, during the process of pulling out the nail, the force on the nail cap and the nail is inclined, so that the force to pull out the nail is relatively large, labor-intensive and time-consuming, and the nail hole will be damaged and surrounding wood. The existing power nail pullers are driven by the motor to drive the gear reduction mechanism and then drive the rotating nail pulling chuck to make the chuck move obliquely. The force on the nail cap and the nail is incline...
