Detailed Description

The utility model discloses do not receive the restriction of following embodiment, can be according to the utility model discloses a technical scheme and actual conditions determine concrete implementation.

In the present invention, for convenience of description, the description of the relative position relationship of the components is described according to the layout mode of the attached drawing 1 in the specification, such as: the positional relationship of front, rear, upper, lower, left, right, etc. is determined in accordance with the layout direction of the drawings of the specification.

The invention will be further described with reference to the following examples and drawings:

the first embodiment is as follows: as shown in the attached drawing 1, the pressing rotary screwdriver comprises a screwdriver rod 1, a screwdriver head 2, a handle 3 and a screw rod 4, the screwdriver head 2 is fixedly connected with the lower end of the screwdriver rod 1, the upper end of the screwdriver rod 1 is fixedly connected with the lower end of the screw rod 4, a cavity 5 with an open lower end is arranged on the handle 3, an internal thread 6 matched with the screw rod 4 is arranged on the inner wall of the middle part of the cavity 5, the screw rod 4 is connected with the internal thread 6 in a threaded mode, a compression spring 7 is fixedly arranged in the cavity 5 corresponding to the position above the internal thread 6 and corresponds to the position above the internal thread, and the upper end of the screw rod 4 is rotatably connected with the compression spring 7 through a rotary connecting mechanism. The application can convert linear motion into rotary motion or convert rotary motion into linear motion through the matching of the screw rod 4 and the internal thread 6, the upper end of the screw rod 4 is rotationally connected with the compression spring 7 through the rotary connecting mechanism to realize the purpose that the screw rod 4 can circumferentially rotate relative to the compression spring 7, when the screw driver is used, the compression spring 7 is in an original length state at the initial state, the screwdriver head 2 is clamped in a tail groove of a screw, an operator presses the handle 3 towards the direction close to the screw, the screw rod 4 positively rotates relative to the handle 3 under the combined action of the internal thread 6 and the screw rod 4 to drive the screwdriver head 2 to positively rotate, and the compression spring 7 is compressed in the positive rotation process of the screw rod 4, so that after the pressing force on the handle 3 is removed, the screw rod 4 reversely rotates relative to the handle 3 under the elastic action of the compression spring 7 to drive the screwdriver head 2 to reversely rotate, therefore, the screwdriver head 2 can rotate positively and negatively only by pressing the handle 3 without manually rotating the handle 3, so that the purpose of mounting and dismounting the screw is realized, and the screwdriver is suitable for mounting and dismounting the screw in a small space which is not convenient for manually rotating the screwdriver, and brings great convenience to field work.

The pressing and rotating screwdriver can be further optimized or/and improved according to the actual requirement:

as shown in the attached figure 1, the rotary connecting mechanism comprises a connecting column 8 and a thrust ball bearing 9, the lower end of the connecting column 8 is fixedly connected with the upper end of a screw rod 4, the upper end of the connecting column 8 is fixedly connected with a shaft ring of a deep groove ball bearing, the lower end of a compression spring 7 is fixedly connected with a seat ring of the deep groove ball bearing, a limiting ring table is arranged on the inner wall of a containing cavity 5 corresponding to the position above an internal thread 6, and the thrust ball bearing 9 is seated on the upper surface of the limiting ring table. Through the setting of spliced pole 8 and deep groove ball bearing, realize that lead screw 4 can be relative compression spring 7 circumference rotatory from this, thrust ball bearing 9 sits and can play the supporting role to thrust ball bearing 9 on the spacing ring bench surface, reduces the atress size of compression spring 7 and thrust ball bearing 9 junction, guarantees that junction intensity is stable.

As shown in fig. 1, an oil hole 10 may be provided on the wall of the receiving cavity 5 corresponding to the position above the internal thread 6. Thereby lubricating oil can be injected into the joint of the internal thread 6 and the screw rod 4 through the oil injection hole 10.

Second embodiment, as shown in fig. 2, the present embodiment is different from the first embodiment only in that the rotary connection mechanism includes a connection column 8 and a deep groove ball bearing 11, the lower end of the connection column is fixedly connected with the upper end of the screw rod 4, the upper end of the connection column 8 is fixedly connected with the inner ring of the deep groove ball bearing 11, the lower end of the compression spring 7 is fixedly connected with the outer ring of the deep groove ball bearing 11, a limit ring table is arranged on the inner wall of the accommodating cavity 5 corresponding to the position above the internal thread 6, and the deep groove ball bearing is seated on the upper surface of the limit ring table. In a similar way, through the arrangement of the connecting column 8 and the deep groove ball bearing, the screw rod 4 can rotate circumferentially relative to the compression spring 7, the deep groove ball bearing is seated on the upper surface of the limiting ring table and can support the deep groove ball bearing, the stress of the joint of the compression spring 7 and the deep groove ball bearing is reduced, and the strength stability of the joint is ensured.

Above technical feature constitutes the utility model discloses a best embodiment, it has stronger adaptability and best implementation effect, can increase and decrease unnecessary technical feature according to actual need, satisfies the demand of different situation.
