Utility model content

Goal of the invention of the present utility model is: for the problem of above-mentioned existence, it is provided that a kind of regular tap spanner, passes through Screw tap seat is uniformly distributed the structure arranging the different shoulder hole of dimensions the extension bar that is slidably connected in shoulder hole Problem present on overcoming above.

The technical solution adopted in the utility model is as follows: a kind of regular tap spanner, including screw tap seat, is connected to screw tap seat The A handle of both sides and B handle, offer non-cylindrical shoulder hole on screw tap seat, be slidably fitted with boosting-rod in shoulder hole, The top of boosting-rod is provided with the step corresponding with shoulder hole；The lower surface of described boosting-rod is provided with screw tap link slot；Described The dimensions more than one of the boosting-rod of shoulder hole and matched installation.

Further, described shoulder hole is square hole, and described boosting-rod is square pole, and described step is square step.

Further, position corresponding with screw tap seat lower surface on described boosting-rod is provided with taper hole, and the end of A handle sets It is equipped with the A taper hole identical with taper hole, also includes the pin being detachably connected in A taper hole.

Further, the shoulder hole of described dimensions more than one is evenly distributed on screw tap seat, and the rank of minimum dimension Ladder hole is positioned at the centre position of screw tap seat.

Further, described screw tap link slot sidewall is provided with pressed component.

Further, described pressed component includes fixing the spring being connected and the free end with spring with screw tap link slot sidewall The fixing tabletting connected.

Further, the number more than one of described spring.

In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:

1, the structure of prior art plug tap spanner is simplified by this utility model, at two, the two ends of screw tap seat handle, and And on screw tap seat, offer non-cylindrical shoulder hole, be slidably installed in shoulder hole the extension bar with step, and Shoulder hole, step, extension bar are disposed as square, use said structure, and extension bar of the present utility model is connected at screw tap On seat and scalable, so that this utility model carries extension bar, when needing to use extension bar, by extension bar from screw tap Haul out in Zuo, convenient and practical, reduce the instrument carrying amount of real user, and save the time found and install extension bar, Thus improve user work efficiency, and then improve practicality of the present utility model.

2, the position that this utility model is corresponding with screw tap seat lower surface on extension bar is provided with taper hole, the end of A handle Portion is provided with the A taper hole identical with taper hole, also includes the pin being detachably connected in A taper hole, uses said structure, is using During extension bar, pin can play location and spacing function, it is to avoid when active force, extension bar slides into screw tap seat；Do not use During extension bar, pin can be taken off and be arranged in A taper hole, it is to avoid pin comes off, thus enhances practicality of the present utility model Property.

3, owing to, during practical screw tap connecting rod and tap tapping, the counteracting force that screw tap is applied by processed hole is very Greatly, user, if not the active force of symmetry then can be increased by the active force on the windeisen time to screw tap inside screw tap Adding a tension, tension and counteracting force act on jointly, then screw tap easily snaps off, especially for the silk of small size Cone, therefore the shoulder hole of minimum dimension is arranged on the geometric center position of screw tap seat by this utility model, remaining shoulder hole is at silk The order being sized size on cone seat is uniformly distributed successively, uses said structure, enhances safety of the present utility model.

4, this utility model is provided with the screw tap link slot for connecting screw tap in the end of extension bar, and connects at screw tap The medial wall of one end of access slot is fixing connects spring, and the free end of spring is fixedly connected on pressing plate, and pressing plate can connect at screw tap , using said structure, this utility model utilizes the elastic acting force of spring to compress screw tap, and then reaches silk in groove slidably The function that cone is fastened as a whole with extension bar, and easy to operate, and then enhance practicality of the present utility model.
