Description

Novel screwdriver

The technical field is as follows:

the invention relates to the field of life, in particular to a novel screwdriver.

Background art:

our country is a large industrial country, and due to the continuous development of society, the requirements of people on the convenience of living tools are higher and higher. At present, most of screwdrivers adopted by people are common double-head replaceable simple screwdrivers in the market, and can be used for common straight screws and cross screws, and other common small parts in daily life, such as external nuts, internal nuts, bolts and the like, need to be solved by using a wrench, so that a complete set of screwdrivers and a complete set of wrenches need to be prepared before work, and tools matched with certain parts cannot be found during work, so that the screwdrivers are not convenient to carry, the working efficiency is reduced, and the cost is high.

The invention content is as follows:

the purpose of the invention is: the novel screwdriver is convenient to carry, can improve the working efficiency and reduce the purchase cost.

In order to achieve the purpose, the technical scheme of the invention is as follows:

the utility model provides a novel screwdriver which characterized in that: the novel screwdriver comprises a floating point metal structure and a rotating structure; the floating point metal structure consists of a plurality of floating point metal probes and floating point metal sleeves; the rotating structure comprises a double-head screw, a screw sleeve, a screwdriver grab handle, a rotating screw and an anti-loosening ring.

Furthermore, one end of the double-end screw is cross-shaped, and the other end of the double-end screw is in a straight shape; one end of the screw rod sleeve is provided with a hexagon nut inner cavity which is connected with the double-end screw rod, and the other end of the screw rod sleeve is provided with a through hole which can pass through the rotary screw.

Furthermore, the rotating screw is matched with the anti-loosening ring for use, and the screw sleeve is connected with the screwdriver grab handle.

Furthermore, the inner part of the floating point metal sleeve is uniformly distributed with cylindrical holes, and the outer part of the floating point metal sleeve is integrated with the screwdriver handle through interference fit.

Furthermore, the floating point metal probe consists of a sleeve, a spring and a metal column; one end of the metal column is a hexagonal prism, and the other end of the metal column is in a round table shape; one end of the sleeve is closed, and the other end of the sleeve is opened; and placing the spring into the sleeve, inserting one end of the circular truncated cone of the metal column into the sleeve, and closing up one end of an opening of the sleeve to effectively connect the sleeve, the spring and the metal column together to form the floating point metal probe.

Furthermore, the floating point metal structure is composed of a plurality of floating point metal probes and floating point metal sleeves, and one end of a sleeve of each floating point metal probe penetrates through the corresponding floating point metal sleeve and is welded inside the screwdriver handle.

The invention has the following advantages:

combine screwdriver and spanner as an organic whole, can not only be used for ordinary word screw and cross screw, can also adapt to the nut of certain size scope, bolt and the part of other shapes (non-rotator) automatically to can be laborsaving, solved the trouble of not portable, improved our use tool's efficiency, reduced our cost of purchasing multiple loaded down with trivial details instrument simultaneously, great reach the convenient light purpose.

The specific implementation mode is as follows:

the invention is further described below with reference to the accompanying drawings.

Referring to fig. 1, a novel screwdriver is characterized in that: the novel screwdriver comprises a rotating structure and a floating point metal structure; the rotary structure comprises a double-end screw (1), a screw sleeve (5), a screwdriver grab handle (2), a rotary screw (4) and an anti-loosening ring (3); the floating point metal structure is composed of a plurality of floating point metal probes (6) and a floating point metal sleeve (7).

Referring to fig. 2, the rotating structure is composed of a double-threaded screw (1), a screwdriver handle (2), a locking ring (3), a rotating screw (4) and a screw sleeve (5), the double-threaded screw (1) is connected with the screw sleeve (5) through a conventional moving pair, and the screw sleeve (5) is connected with the screwdriver handle (2) through the locking ring (3) and the rotating screw (4) and can easily rotate for 90 degrees around the rotating screw.

Referring to fig. 4, the floating point metal probe is composed of a sleeve (7), a spring (8) and a metal column (9); spring (8) quilt cover is inside sleeve (7), and sleeve (7) opening part originally is straight mouthful, and after the round platform one end of metal column (9) inserted the sleeve, makes sleeve (7) opening part shrink again to make sleeve (7), spring (8), metal column (9) three connect and form floating point metal probe. When the metal column (9) is subjected to vertical upward force and the sleeve (7) is fixed, the spring (8) contracts, the metal column (9) also moves upwards, and after the force disappears, the spring (8) restores the original state and enables the metal column (9) to return to the original position.

Referring to fig. 3 and 5, the floating point metal structure is composed of a plurality of floating point metal probes (6), a floating point metal sleeve (10), and one end of a sleeve of each floating point metal probe (6) is inserted into the floating point metal sleeve (10), and the tail end of the sleeve is welded and fixed inside the screwdriver handle. When some floating point metal probes are subjected to vertical upward force, the stressed metal columns (9) move upward as can be seen from the above explanation of fig. 4, and finally all the floating point metal probes can form corresponding shapes together in fig. 3.

When a user uses the novel screwdriver, the user can firstly hold the screwdriver handle (2) to screw the screwed screw to a proper degree, and if the user wants to screw the novel screwdriver more tightly, the screwdriver handle (2) can be rotated to be vertical to the screw sleeve (5) so as to increase the torque, thereby saving labor; referring to fig. 6, taking a hexagon bolt as an example, a user can push the lower end of a screwdriver against the bolt to be rotated, and as can be seen from the explanation of fig. 5, the floating point metal probe in contact with the bolt will move upward and will remain the same as the bolt without contacting with the bolt, thereby forming a shape matched with the bolt, and further rotating the screwdriver to rotate the bolt for achieving the purpose, at this time, the user can still use the rotating structure to increase the torque to save labor.

In conclusion, the screwdriver is simple and ingenious in design structure, combines the screwdriver and the wrench into a whole, can be used for common straight screws and cross screws, can automatically adapt to nuts, bolts and other parts with shapes (non-rotating bodies) within a certain size range, is labor-saving and simple to operate, solves the problem of inconvenience in carrying, greatly improves the living efficiency of people, and achieves the purposes of convenience and easiness.
