Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
As shown in Figure 1-2, embodiments of the present invention relate to a kind of anti-slip type screw tap shed stick, comprise housing 1 and slide block 7, described housing 1 has rectangular indentation, the two side of this rectangular indentation is furnished with between two parties the outstanding slide rail 8 parallel with its long limit, the lower end, both sides of described slide block 7 is furnished with stretches out step 15, the upper end of this slide block 7 is provided with both sides and the cover plate 4 stretching out step 15 and flush, described slide block 7 slides and cover plate 4 and stretch out step 15 and be close to slide rail 8 along slide rail 8, the two ends of described housing 1 are symmetrically installed with handle, wherein the handle of one end is thread handle 2, this thread handle 2 extend in housing 1 and is connected with the other end of slide block 7, the threaded portion 12 of this thread handle 2 is socketed with locking nut 3.
Screw tap shed stick of the present invention mainly improves in two places, one is the improvement of housing 1 and slide block 7, structure originally makes the both sides of slide block 7 directly be embedded in slip in housing 1, due to manufacture craft and the accuracy of slide block 7, also has the reason that the process used can be out of shape, easily upper and lower displacement is there is in slide block 7 when clamping, present structure is that slide block is divided into two parts, this structure is not only installed simply, and slide rail 8 is embraced by slide block 7 and cover plate 4, ensure that slide block 7 can not upper and lower displacement.
Second improvement is the length lengthening thread handle 2, also the length of its threaded upper ends is lengthened, screw thread is socketed a locking nut 3, the rotation of thread handle 2 makes slide block 7 slide to be clamped by screw tap, then rotation lock nut 3 makes the sidewall of itself and housing 1 withstand, this ensures that there thread handle 2 can not rotate, slide block 7 also can not horizontal slip, unless locking nut 3 unclamps.
Supplement as to the one of technical solutions according to the invention, the screw 5 that described cover plate 4 is arranged by two dislocation is connected with the upper end of slide block 7, and the screw 5 of dislocation ensure that can not relative movement between cover plate 4 and slide block 7.
Supplement as to the one of technical solutions according to the invention, described slide block 7 and one end of cover plate 4 are all furnished with W shape projection 10, the opposing sidewalls of the rectangular indentation on described housing 1 is furnished with W connected in star 6, generally the upper end of screw tap is the cylinder that cross section is square, when W shape projection 10 and 6 relative motion of W connected in star, the sidewall that both are parallel to each other arbitrarily is above drawn close relatively by two, the outside opposing sidewalls clamping of screw tap, prevents screw tap from rotating.
Further, the two ends of described housing 1 have been arranged symmetrically with sleeve pipe 9, and described handle extend in sleeve pipe 9, and intensity when handle is connected with housing 1 strengthened by sleeve pipe 9, prevents handle bending or fracture.
Further, the length of the threaded portion 12 of described thread handle 2 is greater than the length of sleeve pipe 9, described locking nut 3 is positioned on the threaded portion 12 outside sleeve pipe 9, locking nut 3 rotate time on threaded portion 12 transverse shifting, withstand with one end of sleeve pipe 9, also can realize the locking of double thread handle 2.
As preferably, one end of described thread handle 2 is connected with and embeds joint pin 13, this embedding joint pin 13 link is in slide block 7 one end endoporus 14, the free end embedding joint pin 13 is the cylinder that diameter is larger, be embedded in endoporus 14, can relatively rotate between itself and slide block 7, but can not horizontal relative movement.
Further, knurled portions 11 is all furnished with outside the outside of described locking nut 3 and the free end of thread handle 2, improve operating personnel with hand rotate thread handle 2 and locking nut 3 time frictional force, when preventing from tightening hand skid and make locking force inadequate.
Further, the threaded portion 12 of described thread handle 2 is wire rod thread, and the spiral shell rib of wire rod thread is wider, is difficult to the situation occurring thread abrasion, and gearratio smoothly.
As further additional project, on described housing 1, the side end face of rectangular indentation embeds and is provided with horizontal liquid column pipe 16, owing to often will rotate the screw tap under vertical state time screw tap shed stick uses, owing to must keep vertical when tap tapping, if there is skew, tapping can be caused to be difficult to carry out or tapping screw thread out and screw are mismatched, so the rotation of screw tap shed stick must keep relative level when tapping, horizontal liquid column pipe 16 there is a bubble, as long as bubble is in a position near middle part just can ensure that screw tap shed stick is in level.
Structure of the present invention is simple, utilize cover plate and slide block to be wrapped by slide rail, ensure that the smoothness of skid, make the slide block when clamping screw tap can not along the displacement of screw tap direction, also on handle, add locking nut, anti-limited slip block is subjected to displacement because of the rotation of handle when clamping.
