Description

Screw tap hank for T-shaped movable handle hand

Technical Field

The utility model relates to a screw tap hank for a T-shaped movable handle, which is formed by fastening screw taps through T-shaped hank heads and can use screw tap hanks with different diameters.

Technical Field

When drilling and tapping, the tap is fastened by screwing the tap handle by using the conventional tap wringer. The pressure and the rotation force to the screw tap hank handle make the rotation of screw tap hank handle different degrees during the tapping, lead to the silk clamping force insufficient, need often to use glue to hold the pincers and go again to screw, influence the work progress, the clamping force is also not strong, the screw tap drops from hank even. When the diameters of the tapping holes are too large, tap handles with different sizes need to be replaced, and a lot of inconvenience is brought to the work.

In order to solve the above problems, chinese patent application publication CN201799970U discloses a tap holder with a compression spring formed between a top block and a holder frame on a portion of a right handle extending into the holder frame, wherein one end of the tap holder block is the holder frame itself, and the other end uses the elastic force of the compression spring to clamp the tap, and the tap can be clamped by a simple operation, so that the clamping force of the tap is increased, but the situation that the clamping force of the tap is not strong enough due to the rotation of the tap holder during tapping still exists. Chinese patent specification CN205074972U discloses a tap hank capable of rotating up by 90 °, and changing the length of the handle of the tap hank by using a connecting sleeve, the tap hank uses two loose clamp blocks, the fixing property of the tap is poor, and the tap is easy to shake up and down. The common screw tap hank consists of a screw tap screwing and clamping screw tap head part and a screw tap hank handle part, the screw tap head is clamped by screwing the screw tap hank handle, but the screw tap hank is not easy to screw the handle and clamp the screw tap head when the internal thread is processed due to thinner handle, so that the screw tap can loosen and fall off, and the screw thread can be damaged due to looseness, so that the screw tap hank is easy to damage; the tap is rotated forcefully, the tap is easy to slip, the handle is smooth, and the tap is not stressed by rotating.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a screw tap wrench capable of firmly clamping aiming at the defects existing in the prior art.

The utility model adopts a T-shaped movable handle to use a screw tap hank, and comprises a part 1 for clamping a screw tap head by the screw tap hank, a screw tap hank handle 3 and a movable cross rod 4 at the end of the screw tap hank handle; the part 1 of the screw tap hank hand for clamping the screw tap head is also provided with a square hole 2 for clamping the screw tap head, the end head of the screw tap hank hand handle 3 is provided with a through hole 5, the movable cross rod 4 of the end head of the screw tap hank hand handle can penetrate through the through hole 5 of the end head of the screw tap hank hand handle 3, the screw tap hank hand handle 3 and the movable cross rod 4 of the end head of the screw tap hank hand handle are in T-shaped cross connection, and the screw tap hank hand is also a deformation of the T-shaped handle screw tap hank hand. The movable cross rod is penetrated into the through hole 5 at the end head of the screw tap handle 3 when in use, the handle 3 and the movable cross rod 4 are in T-shaped cross connection to process internal threads, the movable cross rod is taken out and placed when not in use, the T-shaped head is held by hand, the screw tap chuck can be clamped by screwing threads very easily, the internal threads can be processed very easily by rotating, or the internal threads can be processed without the movable cross rod, and the screw tap is convenient and practical and has an additional effect.

Because there is movable horizontal pole on the handle, hold movable horizontal pole, just screw the thread easily, press from both sides tight tap head, hold movable horizontal pole, the hand is difficult to skid, and rotatory screw tap also makes hard, better processing internal thread easily.

The screw tap head can be well clamped by the T-shaped movable handle by screwing the screw, and the screw tap head can be better forced and cannot slip, because the screw tap head is held by hand, the screw tap chuck can be easily clamped by screwing the screw thread, and the internal screw thread can be easily processed by rotating; the screw tap hank hand adopting the structure can screw the screw thread to clamp the screw tap chuck, rotate the screw tap hank hand to tap simultaneously, the screw tap head can be clamped by the movable cross rod by better rotation screw threads, the screw thread processing is easy and labor-saving, the applicability is favorable for production and popularization and use.
