Fig. 3 is the utility model partial structurtes enlarged drawing.

In figure: tapping handle 1, tap tailgate 2, striking head 3, embedded sets of holes 4, limit hole 4-1, internal screw thread sets of holes 5, circle Plate 6, stepped cylindrical cavity 6-1, external screw thread 7, handle 8, clamping bar 9, sliding block 10, spring 11, elastic shock attenuation layer 12, through-hole 12-1, magnet 13, gag lever post 14.

Specific embodiment

The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:

As shown in Figure 1 to Figure 3, a kind of novel convex taps spanner, including tapping the percussion tail fixed with one end of handle 1 Plate 2,1 other end of handle that taps are fixed with the striking head 3 of cylindrical shape, and embedded sets of holes 4 and interior are provided in the striking head 3 Screw thread sets of holes 5, the embedded sets of holes 4 are connected with internal screw thread sets of holes 5, and the upper surface of the embedded sets of holes 4 is equipped with limit hole 4- 1, it is bolted with round plate 6 in the internal screw thread sets of holes 5, circle 6 outer ring of plate is equipped with to match with internal screw thread sets of holes 5 External screw thread 7, the central side of the circle plate 6 are equipped with cylindrical cavity 6-1, and sliding is equipped with sliding block 10 in the cylindrical cavity 6-1, The clamping bar 9 for being pierced by round 6 top of plate is fixed at the top of the sliding block 10, the top of the clamping bar 9 is fixed with handle 8, Movable spring 11 is socketed on the clamping bar 9, one end of the spring 11 is bonded with the top of sliding block 10, the spring 11 The other end be bonded with cylindrical cavity 6-1 inside top, the bottom of the sliding block 10 is fixed with the limit for being pierced by round 6 bottom of plate Position bar 14, the center of the circle plate 6 are equipped with cavity, are equipped with magnet 13 in the cavity.

The axis of the embedded sets of holes 4 and internal screw thread sets of holes 5 is greater than interior in same position, the diameter of the internal screw thread sets of holes 5 The diameter of screw thread sets of holes 5, setting is in order to which when removing round plate 6, threaded rod can be pierced by from internal screw thread sets of holes 5 in this way.

The outside of the magnet 13 is equipped with one layer of elastic shock attenuation layer 12, is provided with several through-holes on the elastic shock attenuation layer 12 12-1, since magnet 13 is more crisp, elastic shock attenuation layer 12 has the function of protecting magnet 13.

The diameter of the gag lever post 14 is 1mm smaller than the diameter of limit hole 4-1, and gag lever post 14 is facilitated to inject limit hole 4-1.

The spring 11 is compressed spring.

The screw thread of external screw thread 7 and internal screw thread sets of holes 5 on the circle plate 6 is trapezoidal thread, trapezoidal thread self-locking performance It is poor, it is removed convenient for turning.

Working principle:

When tapping spanner tightening nut with convex, when nut and screw rod one end spacing are smaller, round plate 6 is passed through into screw thread It is mounted in striking head 3, loading onto rear gag lever post 14 will be stuck in limit hole 4-1, due to when round plate 6 is installed in rotation, by 1mm smaller than the diameter of limit hole 4-1 in the diameter of gag lever post 14, gag lever post 14 is easier to inject limit hole 4-1, prevents from tapping and pull Hand is tapped the round plate 6 of vibration and gets off from 3 loose or dislocation of striking head.With assembled spanner nutting, due to round plate 6 Interior magnet 13 acts on, and the axial direction that magnet 13 can limit between spanner and nut moves left and right, and is struck with sledgehammer and taps tailgate 2 Accuracy it is higher, safety greatly improves, and since in shots, 13 brittleness of magnet is larger, the bullet of its appearance is arranged in Has the function of shock-absorbing protecting magnet 13 on property buffer layer 12, the through-hole 12-1 on elastic shock attenuation layer 12 can prevent elastic shock attenuation Layer 12 externally weakens the magnetic force of magnet 13, guarantees that spanner does not move axially；(such as heat exchanger when twisting the nut on longer screw Deng) portable handle 8 can be used, handle 8 is lifted gag lever post 14 by clamping bar 9, is rotating round plate 6 from striking head 3 Back-out come, due on round plate 6 external screw thread 7 and internal screw thread sets of holes 5 screw thread be trapezoidal thread, trapezoidal thread self-locking performance compared with Difference is quickly removed convenient for rotating round plate 6, and such striking head 3 covers on nut with regard to the whole screw rod that can pass through, Bu Huiyou The use of spanner is influenced in spiro rod length, is applicable in preferable.

The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this The principle of utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various change And improvement, these various changes and improvements fall within the scope of the claimed invention.The utility model requires protection scope It is defined by the appending claims and its equivalent thereof.
