Abstract
The utility model discloses a lengthened tool for manual tapping. The lengthened tool for the manual tapping comprises a manual tapping handle and a tapping extension bar. The lengthened tool for the manual tapping is characterized in that a tetragonal column matched with a square groove hole of the manual tapping handle is arranged at the upper end of the tapping extension bar, a tapping connecting sleeve is arranged at the lower end of the tapping extension bar, and a square groove hole is formed in the tapping connecting sleeve. Due to the fact that the tapping extension bar is adopted, no matter how deep a machined threaded hole is, the proper length of the manual tapping handle and/or the tapping connecting sleeve can be selected to enable the manual tapping handle to have a rotation space, and therefore the lengthened tool for the manual tapping can be used for machining threaded holes with various depths, and is extremely wide in universality.
Description
Technical field
The utility model relates to field of tool, relates in particular to tapping tool, specifically a kind of manual tapping instrument.
Background technology
Tapping is a kind of machined form commonly used, completes by the manual screw tap handle operation of a standard.Conventional manual screw tap handle is a strip strand hand, is provided with square slotted eye at middle body, and two end surfaces are provided with anti-slip veins.Be provided with clamp in this square slotted eye.During operation, the square groove borehole jack is contained on screw tap, clamp clamps this screw tap, rotate manual screw tap handle can be on processed parts tap out.
Yet; in the process of machine components processing; particularly during manual thread mill drilling; usually can encounter very and under running-deep-hole, screwed hole be arranged; perhaps very dark step, groove bottom have screwed hole, because the manual screw tap handle of standard is often very short, will certainly increase like this difficulty of processing of part; also can give the less screw tap cause danger of diameter, easily break in the hole.Aspect the maintenance of production equipment, often also can meet the hole that some need to be repaired, taken by other parts the space that screw tap strand hand-screw turns, if because a screwed hole, and equipment is torn open greatly, will certainly waste a lot of times, not only delayed production, but also might damage equipment.Therefore seek a kind of safe, tool method rapidly, the processing problems that solves difficult thread mill drilling is very necessary.
Summary of the invention
To be solved in the utility model is the problems referred to above that prior art exists, and aims to provide a manual tapping instrument, and can conveniently process has screwed hole under running-deep-hole very much, perhaps the screwed hole of very dark step, groove bottom.
For addressing the above problem, the utility model is by the following technical solutions: manual tapping instrument, comprise manual screw tap handle and tapping extension bar, the upper end that it is characterized in that described tapping extension bar is provided with the tetragonal prism that matches with the square slotted eye of described manual screw tap handle, described tapping extension bar lower end is provided with the tapping female connector, and described tapping female connector offers square slotted eye.
Manual tapping instrument of the present utility model operates by the following method:
First the clamp on manual screw tap handle is unclamped, the upper end of tapping extension bar is put into manual screw tap handle and clamped, the more square handle of screw tap is put into the square slotted eye of tapping female connector, at last screw tap is aimed at the hole tapping that will process and get final product.
Manual tapping instrument of the present utility model, owing to having adopted the tapping extension bar, no matter how dark processed screwed hole have, all can make manual screw tap handle that the space of rotation is arranged by the length of selecting suitable manual screw tap handle and/or tapping female connector, therefore can be used for processing the screwed hole of the various degree of depth, versatility is extremely extensive.
According to the utility model, described tapping extension bar can be processed into one with described tapping female connector, and the tetragonal prism that also can arrange by tapping extension bar lower end realizes that with the mode that the square slotted eye in described tapping female connector coordinates described tapping extension bar and described tapping female connector removably connect.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use state diagram of the present utility model.
The specific embodiment
With reference to Fig. 1, manual tapping instrument of the present utility model comprises manual screw tap handle 4, tapping extension bar 3 and tapping female connector 2.Described manual screw tap handle 4 is common structure, and its central authorities are provided with square slotted eye, is provided with clamp in this square slotted eye.The upper end of described tapping extension bar 3 is provided with the tetragonal prism that matches with the square slotted eye of described manual screw tap handle 4, and the lower end is provided with the tetragonal prism that matches with the square slotted eye of described tapping female connector 2.Offer the square slotted eye of perforation in described tapping female connector 2.
With reference to Fig. 2, manual tapping instrument of the present utility model operates in the following manner:
First the clamp with manual screw tap handle 4 unclamps, and the upper end tetragonal prism of tapping extension bar 3 is put into the square slotted eye of manual screw tap handle 4 and clamped; Again the lower end tetragonal prism of tapping bar 3 in the square slotted eye of top insertion tapping female connector 2.Then the square handle of screw tap 1 is put into the square slotted eye of tapping female connector 2 from below, the length of tapping female connector 2 can be according to processed screw thread the degree of depth situation decision of workpiece 5, until allow manual screw tap handle 4 that the space of rotation is arranged, at last screw tap 1 is aimed at the hole tapping that will process and get final product.
What should be understood that is: above-described embodiment is just to explanation of the present utility model, rather than to restriction of the present utility model, any utility model that does not exceed in the utility model connotation scope is created, within all falling into protection domain of the present utility model.
