Specific implementation mode
Specific embodiment of the present utility model is made into one by the description to optimum embodiment below against attached drawing
Step detailed description.
The utility model specific embodiment is：As shown in Figure 1, a kind of tapping utensil, including screw tap 1 and with screw tap 1
Connected handle 2,1 middle part of screw tap are provided with matched balance bracket 3, and 1 top of screw tap is arranged limiting balance holder 3 and moves
Elastic spacing one 4, the central axis upright of the lower end and screw tap 1 of the balance bracket 3.
Specifically, as shown in Fig. 2, screw tap 1 includes tapping section 11, conical section 12, straight bar section 13 and square toes section 14, the cone
The junction of shape section 12 and straight bar section 13 is connected with the clamping of balance bracket 3, and the square toes section 14 is connected with the clamping of handle 2.Specifically
Connection structure is that the small end of conical section 12 is connected with tapping section 11, and the big end of conical section 12 is connected with straight bar section 13, conical section 12
Outside diameter be more than the diameter of straight bar section 13, balance bracket 3 and be clamped therewith convenient for accommodating.
Specifically, balance bracket 3 includes Coupling 31 and link 32, the Coupling 31 be connected to conical section 12 with it is straight
The junction of rod segment 13, the link 32 are fixedly installed along the circumferencial direction of Coupling 31, make overall structure balance and stability；For
Coupling 31 is set to be clamped and not fall off, the internal diameter of Coupling 31 is less than the outside diameter of conical section 12；In order to further increase
The stability of strutting system and counterbalance effect of link 32, link 32 include that three connecting rods 321 and three 321 lower ends of connecting rod are solid
Fixed locating ring 322, Coupling 31, connecting rod 321 and locating ring 322 can be connected as one by welding, locating ring
The central axis upright of 322 place planes and screw tap 1, prevents the crooked of tapping process plug tap 1, improves tapping precision.
Specifically, elastic spacing one 4 includes limit spring 41 and locating piece 42, and limit spring 41 is arranged in balance bracket 3
Between locating piece 42, locating piece 42 is adapted with screw tap 1, plays the role of elastic spacing, and will not in tapping process
Limit the movement of screw tap 1；In order to need to adjust the tapping depth of screw tap 1 according to operating mode, locating piece 42 may be configured as flange face spiral shell
External screw thread is arranged in the top of mother, the straight bar section 13 of screw tap 1, and flange surface nut is threadedly coupled with the straight bar section 13 of screw tap 1, passes through tune
Save position of the flange surface nut on screw tap 1, the height of adjustable and balancing holder 3, to realize to 1 tapping depth of screw tap
It adjusts.
The process of tapping operation is carried out with the tapping utensil is：It is needed to adjust tapping depth, tool according to operating mode first
Body, position of the turn flange surface nut on screw tap 1, then Coupling 31 on balance bracket 3 is in tapping and limit spring
41 and flange surface nut contradict, to realize the adjusting to 1 tapping depth of screw tap；Then handle 2 is mounted on square toes section 14,
It rotates clockwise handle 2 and starts tapping, at this time the locating ring 322 of 3 lower end of balance bracket and processing plane contact, in the mistake of tapping
Cheng Zhong is limited since limit spring 41 and flange surface nut are contradicted with 3 elasticity of balance bracket always, balance bracket 3 also always with
It processes plane to contradict, keeps screw tap 1 vertical with processing plane always, until tapping terminates, this process is simple to operate, and keeps away
Exempt from that tapping is crooked, has improved the precision of tapping, be suitable for popularization and application.
To sum up, the tapping utensil is simple to operate, makes processed plane vertical with screw tap always in tapping process,
It avoids that tapping is crooked, improves the precision of tapping.
The above, some principles of the utility model that only explains through diagrams, this specification are not intended to this practicality
