Screw delivery rack for electric drill

Abstract

The invention discloses a screw delivery rack for an electric drill; the screw delivery rack comprises a screw pushing mechanism, a screw discharging mechanism and a screw turning mechanism, wherein the screw pushing mechanism comprises a rack plate, a through pipe and a pushing bolt, the rack plate is levelly arranged at the upper bottom end of the electric drill and fixed with the electric drillmachine body, the through pipe at the front end of the rack plate and the pushing bolt at the rear end of the rack plate are linearly arranged, a middle card holder moves and places a screw box of the screw discharging mechanism, each bin clamping bottom cavity, front and rear through holes in the box are respectively located and aligned with the through pipe and the pushing bolt; respectively, the rear end of the bolt of the screw turning mechanism is elastically moved and clamped in a bolt seat on one side of the rack plate, and a concave cone clamp of the folding plate at the top of a rotating rod is placed in front of a through pipe bundle opening, or the concave cone clamp of the front moving folding plate of the rotating rod rotates to the front of an electric drill driver rod. Thescrew delivery rack has a simple structure, low cost, and does not require electric drive to drive the screw; the current situation that the screw machine in the prior art is cumbersome to carry, complicated to operate, and has a small application range is changed; and the product has competitiveness and wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of electric drills, in particular to a screw delivery device for a hand-held electric drill. Background technique [0002] Electric drills are widely used to tighten screws. It is very troublesome to transfer screws manually, and the screws are easy to be lost and crooked. In the prior art, the automatic delivery of electric drill screws mostly adopts the method of vacuum pump suction nails, which needs to be equipped with other equipment. It is difficult to carry and operate. Electric drill screws There are also innovations in the delivery, such as the utility model patent "an automatic feeding electric screwdriver" (patent number: 200850151815.X) which adopts the technical solution of connecting the feeding component at the head of the screwdriver with the inclined pneumatic feeding tube; the utility model patent "automatic lock Screw machine" (Patent No.: 2013203296291), which uses two feed tubes to trans...

[0002] Electric drills are widely used to tighten screws. It is very troublesome to transfer screws manually, and the screws are easy to be lost and crooked. In the prior art, the automatic delivery of electric drill screws mostly adopts the method of vacuum pump suction nails, which needs to be equipped with other equipment. It is difficult to carry and operate. Electric drill screws There are also innovations in the delivery, such as the utility model patent "an automatic feeding electric screwdriver" (patent number: 200850151815.X) which adopts the technical solution of connecting the feeding component at the head of the screwdriver with the inclined pneumatic feeding tube; the utility model patent "automatic lock Screw machine" (Patent No.: 2013203296291), which uses two feed tubes to transmit screws with different diameters to multiple vertical piercing holes on the distribution block, and the distribution block moves horizontally with a single penetration hole and When the material guide holes are concentric, the screws with different diameters fall to the material guide holes; although the above technology improves the efficiency, there are still problems such as the inclination of the feeding pipe and the inability to transport long-stem screws, high cost of electric drive, inconvenient operation of equipment, and small scope of application, etc. limitations
