Utility model content
In order to solve the problem, the utility model provides a kind of manual tapping instrument of improvement, installs and uses reliable convenience, difficult drop-off, can process the screwed hole under very dark hole safety quickly, or very dark step, groove bottom screwed hole.
For solving the problems of the technologies described above, the manual tapping instrument of a kind of improvement of the utility model, comprise manual screw tap handle, tapping bar, match with manual screw tap handle and install in the upper end of this tapping bar, it also comprises a removable tapping female connector, an installation through hole is offered in this tapping female connector, and the upper end of this tapping female connector, the side of lower end offer screw hole respectively, the upper end that screw hole coordinates the screw of correspondingly-sized tapping female connector to be installed respectively by the coupling mechanism force of screw is in the lower end of tapping bar and lower end screw tap being arranged on tapping female connector.
Further, the quantity of screw hole is 8, and wherein 4 screw holes are evenly distributed on the side of the upper end of tapping female connector, and other four screw holes are evenly distributed on the side of the lower end of tapping female connector.Such structural design can ensure that the coupling mechanism force of screw is enough large thus tapping female connector not easily comes off from the lower end of tapping bar, screw tap not easily comes off from the lower end of tapping female connector, and the uniform structural design of screw hole can ensure the coupling mechanism force equilibrium of the screw suffered by surrounding of the surrounding of the lower end of tapping bar and the upper end of screw tap thus ensure that the axis of tapping bar, tapping female connector and screw tap is on same straight line, ensures the quality of screwed hole during manual tapping.
Further again, the upper end of tapping bar, lower end are respectively arranged with a tetragonal prism structure, and manual screw tap handle is set to a spanner, and one end of spanner offers a square slotted eye matched with the tetragonal prism of the upper end of tapping bar; The first half of installing through hole is set to the square opening matched with the tetragonal prism of the lower end of tapping bar, and the latter half of installing through hole is set to the square opening matched with the tetragonal prism of the upper end of screw tap.Such structural design can ensure that, in manual tapping process, screw tap can provide enough large torsion, ensures that the axis of tapping bar, tapping female connector and screw tap is on same straight line, ensures the quality of screwed hole during manual tapping further simultaneously.
The beneficial effects of the utility model are: this product installs and uses reliable convenience, difficult drop-off, can process the screwed hole under very dark hole safety quickly, or very dark step, groove bottom screwed hole.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of a preferred embodiment of the present utility model;
Fig. 2 is the structural representation of the utility model tapping female connector;
Fig. 3 is the structural representation of the utility model tapping female connector.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, a kind of manual tapping instrument of improvement, comprise manual screw tap handle 1, tapping bar 2, match with manual screw tap handle 1 and install in the upper end of this tapping bar 2, it also comprises a removable tapping female connector 3, an installation through hole 31 is offered in this tapping female connector 3, and the side of the upper end of this tapping female connector 3, lower end offers screw hole 32 respectively, screw hole 32 coordinates the screw of correspondingly-sized respectively the upper end of tapping female connector 3 be arranged on the lower end of tapping bar 2 by the coupling mechanism force of screw and screw tap 4 be arranged on the lower end of tapping female connector 3.
In the preferred embodiment, the quantity of screw hole 32 is 8, and wherein 4 screw holes 32 are evenly distributed on the side of the upper end of tapping female connector 3, and other four screw holes 32 are evenly distributed on the side of the lower end of tapping female connector 3.Such structural design can ensure that the coupling mechanism force of screw is enough large thus tapping female connector 3 not easily comes off from the lower end of tapping bar 2, screw tap 4 not easily comes off from the lower end of tapping female connector 3, and the uniform structural design of screw hole 32 can ensure the coupling mechanism force equilibrium of the screw suffered by surrounding of the surrounding of the lower end of tapping bar 2 and the upper end of screw tap 4 thus ensure that the axis of tapping bar 2, tapping female connector 3 and screw tap 4 is on same straight line, ensures the quality of screwed hole during manual tapping.
In addition, the upper end of tapping bar 2, lower end are respectively arranged with a tetragonal prism structure, and manual screw tap handle 1 is set to a spanner, and one end of spanner offers a square slotted eye matched with the tetragonal prism of the upper end of tapping bar 2.
In addition, as shown in Figure 2, the size of installing the first half of through hole 31 is not defined as and matches completely with the tetragonal prism size of the lower end of tapping bar 2, the size of the latter half of installing hole 31 is not defined as and matches completely with the size of the tetragonal prism of the upper end of screw tap 4, as long as can ensure that the upper end of tapping female connector 3 can be arranged on the lower end of tapping bar 2 and screw tap 4 be arranged on the lower end of tapping female connector 3 by the screw in the screw hole 32 of tapping female connector 3 side, the size of that is installing through hole 31 can be set to unified size, be conducive to the versatility improving tapping female connector 3 like this.
But preferably, the first half of installing through hole 31 is set to the square opening matched with the tetragonal prism of the lower end of tapping bar, the latter half of installing through hole 31 is set to the square opening matched with the tetragonal prism of the upper end of screw tap, such structural design can ensure in manual tapping process, screw tap 4 can provide enough large torsion, ensure that the axis of tapping bar 2, tapping female connector 3 and screw tap 4 is on same straight line, ensures the quality of screwed hole during manual tapping further simultaneously.
As shown in Figure 3, the size of tapping female connector 3 can decide according to the size of screw tap 4 reality, and tapping female connector 3 is due to dismantled and assembled, therefore very easy to use.
The utility model adopts the coupling mechanism force of screw to install tapping female connector 3 and screw tap 4, also has another one benefit: the length that the utility model can lengthen according to screw tap 4 actual needs regulates the tetragonal prism of tapping bar 2 lower end to stretch into install the tetragonal prism of the upper end of the length in through hole 31 and screw tap 4 to stretch into the length of installing in through hole 31, thus realize the fine setting of manual tapping length, versatility of the present utility model and practicality are provided further.
In sum, the utility model installs and uses reliable convenience, difficult drop-off, can process the screwed hole under very dark hole safety quickly, or very dark step, groove bottom screwed hole.
Certainly; the manual tapping instrument of a kind of improvement of the utility model can also have other change; quantity as screw hole is different; the size of screw hole is different; the classification of manual screw tap handle is different, and the length of tapping bar is different, and the length of tapping female connector is different; install the shape of through hole and the change etc. of size, such change all drops within protection domain of the present utility model.
