Description

Screw tap hank hand fixing device for hand

Technical Field

The utility model relates to a hand screw tap wringing hand fixing device, which is formed by a fixed wringing hand frame in part and a movable clamping block matched with the fixed wringing hand frame in part, wherein the screw tap wringing hand is formed by two parts.

Background

When internal threads are drilled, the tap is fastened by screwing the tap handle by using the conventional tap wringer. Pressure and rotation force to the tap handle make the rotation of tap handle different degree when processing the internal thread, lead to the clamping force of screw tap insufficient, often need to use glue to hold the pincers and go again to screw, influence the work progress, the clamping force is also not strong, even the screw tap drops from the hank. When the diameter difference of the machined internal thread holes is too large, screw tap twisting hands with different sizes need to be replaced, and the like, so that a great deal of inconvenience is brought to work.

In order to solve the above problems, chinese patent application publication CN201799970U discloses a tap holder having 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 of the tap holder block is adapted to clamp the tap by using the elastic force of the compression spring, and the tap holder block can clamp the tap 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 handle when the internal thread is formed still exists. Chinese patent specification CN205074972U discloses a tap wrench capable of rotating upward by 90 ° to change the length of the handle with a connecting sleeve, the tap wrench uses two loose clamp blocks, the fixing property of the tap is poor, and the tap is easy to shake up and down.

Disclosure of Invention

The technical problem solved by the utility model is to provide the hand screw tap twisting fixing device aiming at the defects existing in the prior art.

The utility model provides a hand tap hank hand fixing device, including fixed part and movable part, the fixed part includes hank hand frame 1, fixed handle 6, hank hand frame 1 has first through-hole 4, there is isosceles right triangle recess in the middle of the hank hand frame 1 inner wall, the movable part is a movable clamp splice, there is isosceles right triangle recess in the middle of the clamp splice inner wall, there is second through-hole 5 with the first through-hole 4 matched with of hank hand frame 1, two bolts 10 pass first through-hole 4 in the hank hand frame and the second through-hole 5 of movable clamp splice, two nuts 9 are screwed on two bolts 10, the movable clamp splice is fixed in hank hand frame 1, two isosceles right triangle recesses that correspond constitute a square clamp hole 2, fixed part both ends have fixed handle 6, fixed handle 6 both ends are provided with the internal thread, two movable handles 7 with the external screw thread screw to the internal thread inside at screw tap hank hand fixed handle both ends.

The device is convenient to install and use, high in applicability, low in manufacturing cost and suitable for popularization and use.

description of the embodiments

Embodiments of the tap holder according to the present utility model will be described in detail with reference to the accompanying drawings.

Embodiment 1: as shown in figure 1, the movable clamping block matched with the fixed winch frame is placed in the fixed winch frame, after being tightly connected, the winch frame and two isosceles right triangle grooves on the clamping block form a small square clamping hole 2 for clamping a screw tap, two bolts 10 penetrate through a first through hole 4 on the inner wall of the fixed winch frame and a second through hole 5 on the movable clamping block matched with the fixed winch frame, two nuts 9 are screwed on the bolts 10, and the nuts are screwed to enable the clamping hole 2 to better clamp the screw tap head, so that high-quality internal threads are processed; for convenience, two wing nuts 8 can be screwed on the bolts 10, so that the manual operation is facilitated without a spanner; the movable handle 7 with external threads can be screwed into the internal threads of the blind holes at the two ends of the fixed handle 6 of the screw tap hank, and the handle is lengthened, so that the manual processing of the internal threads is more labor-saving.

Embodiment 2: as shown in figure 1, the handles 6 are fixed at two ends of the handle frame, the handles 6 are provided with non-through holes with the length of 20mm, internal threads are processed in the holes, external threads on the movable handle 7 are matched with the internal threads of the handles 6 at two ends, the movable handle 7 can be screwed out and screwed in the non-through holes with the length of 20mm of the handles 6 at two ends of the handle frame, the length of a screw tap handle is prolonged, the internal threads can be easily processed, the screw tap handle is provided with movable handles 7 with different lengths, and screw tap handles with different lengths can be formed according to requirements.

Embodiment 3: as shown in FIG. 3, the movable clamping block part is in a construction view, two bolt holes 3 on the clamping block are not provided with internal threads, the diameter of the bolt holes is 0.5mm larger than that of the bolt holes on the wringing handle frame, and the clamping block slides up and down when a screw tap is clamped, so that the screw tap wringing handle frame is convenient and rapid to install.
