Description

Technical Field

[0001] The utility model relates to a screwdriver, in particular to a precision screwdriver. Background Art

[0002] When you press the storage box of Fanttik's product, the storage box and the precision batch host will pop up at the same time; if the user touches them by mistake, they will pop up at the same time. When re-locking, you have to press the storage box and the precision batch host separately, which is cumbersome; and it is easy to cause the host to fall to the ground. Utility Model Content

[0003] In order to solve the defects of the above-mentioned prior art, the present invention provides a precision screwdriver. When the user presses the storage box, the storage box and the precision screwdriver body will not pop up at the same time; when the user accidentally touches it and wants to relock it, he only needs to press the storage box; and it is not easy to cause the body to fall to the ground.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a precision screwdriver, comprising an outer box and a base fixed to one end of the outer box, a storage box, and a main unit, wherein the base and the storage box are connected by a self-locking structure, and a metal pin is also fixed to the base, and the working head of the main unit has a groove, and a magnet is fixed inside the groove, and the magnet can be adsorbed on the metal pin to fix the main unit; and further comprising a spring, which is installed inside the storage box and sleeved on the outside of the main unit head.

[0005] Furthermore, a self-locking switch is provided inside the base, and a pin is provided at the end of the storage box, and the pin can be locked in the self-locking switch.

[0006] Furthermore, the base is provided with a central leg, and the central leg fixes the metal pin. The metal pin is a long column, one end of which is fixed to the central leg, and the other end can be extended into the groove to magnetically connect to the magnet.

[0007] In summary, the present invention has achieved the following technical effects:

[0008] When the spring of the utility model is in the compressed state 2, the elastic force is less than the sum of the attraction between the magnet and the metal pin and the weight of the host; when the spring is in the compressed state 3, the elastic force is greater than the weight of the host and the host is now higher than the surface of the storage box; when the storage box is pressed, only the storage box is ejected, and the host does not move; the host will only eject when the user removes the storage box;

[0009] The storage box of the utility model has four pins, and the outer box is provided with two self-locking switches; when the storage box is placed in the outer box, the pins will enter the self-locking switches and be locked; when the storage box is pressed once more, the self-locking switches will be unlocked and the storage box will pop up.

[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0015] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0016] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary.

[0017] Example:

[0018] like Figure 1 As shown, a precision screwdriver comprises an outer box 1 and a base 2 fixed to one end of the outer box 1 , a storage box 3 , and a main unit 31 located inside the storage box 3 .

[0019] The base 2 and the storage box 3 are connected by a self-locking structure, wherein a self-locking switch 4 is provided inside the base 2, and a pin 5 is provided at the end of the storage box 3, and the pin 5 can be locked in the self-locking switch 4. The self-locking switch 4 adopts an existing structure and will not be described in detail here.

[0020] The base 2 is also fixed with a metal pin 6, and the working head of the main unit 31 has a groove, and a magnet 7 is fixed inside the groove. The magnet 7 can be adsorbed on the metal pin 6 to fix the main unit 31; it also includes a spring 8, which is installed inside the storage box 3 and is sleeved on the outside of the head of the main unit 31.

[0021] The base 2 is provided with a central leg 21, and the central leg 21 fixes the metal pin 6. The metal pin 6 is a long column, one end of which is fixed to the central leg 21, and the other end can be extended into the groove to be magnetically connected to the magnet 7.

[0022] The spring 8 is fixed in the storage box. When the host 31 is placed inside the storage box, the head of the host is inserted into the spring 8, and the groove is aligned with the metal pin 6, so that the metal pin 6 can enter the groove of the host and be adsorbed by the magnet to fix the host.

[0023] The magnet of the utility model is assembled inside the working head of the host and is connected to the host as a whole; the metal pin is fixed in the base of the outer box. When the storage box is locked in the outer box through the self-locking switch 4 and the pin 5, the host is pressed, and the magnet attracts the metal pin, thereby fixing the host. At this time, the spring is in a compressed state 1; when the storage box is pressed to unlock the self-locking switch and the storage box pops out from the outer box, its pop-up distance causes the spring to be further compressed. At this time, the spring force is still less than the sum of the suction force between the magnet and the metal pin and the weight of the host, so the host cannot be bounced up; when the user needs to use it, pulling out the storage box will move the host outward, which will cause the magnet to separate from the metal pin. At this time, the spring can bounce the host a distance, and the spring is in a compressed state 3; making the host higher than the surface of the storage box for easy picking.

[0024] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
