Description

Technical Field

[0001] The present invention relates to the technical field of hardware tools, in particular to an electric precision screwdriver. Background Art

[0002] A screwdriver is a daily tool for removing and installing screws. Since the operation process of removing and installing screws is a repetitive mechanical motion, people generally use electric screwdrivers to complete the process. For the convenience of operation, some electric screwdrivers are rechargeable to increase their portability. However, when charging, the existing screwdrivers need to eject the storage bin and the body completely before charging. During charging, the body and the storage bin are separated, which is easy to be affected. At the same time, when using, the storage bin and the body of the existing screwdriver need to be ejected completely from the shell before the body and the screwdriver can be taken out, which has the problems of difficult storage and cumbersome operation. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides an electric precision screwdriver to solve the problem that the current precision screwdriver needs to eject the storage compartment and the body completely before charging, and is difficult to store and cumbersome to operate.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] Provided is an electric precision screwdriver, comprising a housing, a storage bin, and a main body. In a stored state, the main body is stored in the storage bin, and the housing is stored in the housing in the stored state. The bottom of the main body faces outward and is provided with a charging port. In a released state, the storage bin is separated from the housing, and the main body is separated from the storage bin. In the stored state, when the bottom of the storage bin and the bottom of the main body approach each other, the main body gradually detaches from the storage bin.

[0006] As a further improvement of the above technical solution, the storage bin includes an opening for accommodating the main body, an adsorption part is provided at the bottom of the opening, and a magnet is provided at the top of the main body. In the storage state, the magnet adsorbs the adsorption part to connect the main body and the storage bin.

[0007] As a further improvement of the above technical solution, the adsorption portion includes a metal pin arranged toward the main body.

[0008] As a further improvement of the above technical solution, an elastic member is sleeved on the outer side of the adsorption portion.

[0010] As a further improvement of the above technical solution, one end of the elastic member is fixed to the bottom of the storage bin, and the other end abuts against the main body.

[0011] As a further improvement of the above technical solution, the elastic member includes a spring, one end of which is fixed to the bottom of the storage bin, and the other end of which is supported on the top of the main body and is sleeved on the periphery of the adsorption portion.

[0012] As a further improvement of the above technical solution, there is a compression state between the storage state and the release state. In the compression state, the opening end face of the storage bin is directed toward the bottom of the shell over the storage port end face of the shell, and the opening end face of the main body is directed away from the bottom of the shell over the storage port end face of the shell.

[0013] As a further improvement of the above technical solution, in the storage state, the bottom surface of the main body, the opening end surface of the storage bin and the storage opening end surface of the shell are coplanar.

[0014] As a further improvement of the above technical solution, in the process from the storage state to the release state, the storage bin first moves toward the bottom of the shell and then moves away from the bottom of the shell, and the main body always moves toward the direction away from the bottom of the shell.

[0015] The beneficial effects of the present invention are as follows: an electric precision screwdriver is provided, comprising a shell, a storage bin and a main body; in the storage state, the main body is stored in the storage bin, the shell is stored in the shell in the storage state, the bottom of the main body faces outward and is provided with a charging port; in the release state, the storage bin is separated from the shell, and the main body is separated from the storage bin; in the storage state, when the bottom of the storage bin and the bottom of the main body are close to each other, the main body gradually separates from the storage bin. The design adopted by the present invention avoids the problem in the prior art that the main body needs to be completely removed from the storage bin and the shell before charging, and enables the operator to limit the operating object during charging to the entire electric precision screwdriver without considering the position of the removed shell or storage bin. The operator only needs to charge directly in the storage state. At the same time, the present invention realizes the action of ejecting the main body and separating the shell while releasing the storage bin, which is simple and efficient to operate.

It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict.

[0025] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature or indirectly fixed or connected to the other feature. Furthermore, terms such as "upper," "lower," "left," "right," "front," and "rear" used in this disclosure are intended solely to describe the relative positions of the components of the disclosure as shown in the accompanying drawings.

[0026] In addition, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. The terms used in this specification are only used to describe specific embodiments and are not intended to limit the present invention. The term "and / or" as used herein includes any combination of one or more of the related listed items.

[0027] Please refer to Figure 1-3This embodiment discloses a precision electric screwdriver 100, which includes a housing 110, a storage compartment 120, and a main body 130. The main body 130 is the main working component of the electric precision screwdriver 100, and is used to cooperate with various screw bits (such as screw heads, etc.) to install and release various components. The storage compartment 120 can serve as a storage container for the main body 130 and can also store multiple screw bits at the same time, which is convenient for the operator to use and replace the screw bits. Figure 1 This is a front view of an electric precision screwdriver in a first state according to an embodiment of the present invention, Figure 2 This is a left side view of an electric precision screwdriver in a first state according to an embodiment of the present invention, Figure 3 1 is a cross-sectional view of an electric precision screwdriver in a first state according to an embodiment of the present invention.

[0028] It should be noted that in this embodiment, the main body 130 is provided with a charging port 131, preferably a Type-C port, which can meet the following requirements: when the main body 130 is fully stored, it can still be charged, thereby avoiding the problem in the prior art that the main body 130 needs to be completely removed from the storage bin 120 and the shell 110 before charging. When the operator charges the main body 130, there is no need to remove the main body 130, so that the operator's operation object during charging is limited to the entire electric precision screwdriver 100, without having to consider the position of the removed shell 110 or the storage bin 120, and only needs to be charged directly in the storage state.

[0029] In addition, in another embodiment, the charging port 131 can be set to other specifications, that is, it can be set to an interface such as MicroUSB, Lightning, etc., or multiple charging ports 131 can be provided at the same time to adapt to different charging environments.

[0030] In this embodiment, the electric precision screwdriver 100 includes at least three states, namely the first state, the second state and the third state. Figure 1-3 Schematic diagram of an electric precision screwdriver in a first state according to an embodiment of the present invention, see the attached Figure 4-7 , among which, Figure 4 This is a front view of an electric precision screwdriver in a second state according to an embodiment of the present invention, Figure 5 is a cross-sectional view of an electric precision screwdriver in a second state according to an embodiment of the present invention, Figure 6 This is a front view of an electric precision screwdriver in a third state according to an embodiment of the present invention, Figure 7 1 is a cross-sectional view of an electric precision screwdriver in a third state according to an embodiment of the present invention.

[0031] The second state is an intermediate state between the first state and the third state, as follows:

[0032] The first state is the storage state. In the storage state, the main body 130 is stored in the storage bin 120. At this time, the storage bin 120 is also stored in the shell 110, so that the main body 130 and the storage bin 120 are completely stored in the shell 110, so that the electric precision screwdriver is in a columnar shape after being stored, which is convenient for the operator to store and handle. At the same time, it also protects the storage bin 120 and the main body 130. Preferably, in the first state, the bottom surface of the main body 130, the open end surface of the storage bin 120 and the open end surface of the shell 110 are coplanar.

[0033] The second state is a separation state. In the second state, the main body 130, the storage bin 120 and the shell 110 are in the process of being released from each other. At this time, not only the storage bin 120 is being separated from the shell 110, but the main body 130 is also being separated from the storage bin 120.

[0034] The third state is a released state. In the third state, the main body 130 and the storage bin 120 are separated. At this time, the storage bin 120 is also separated from the shell 110. In this case, the operator can freely access the main body 130 and / or the storage bin 120.

[0035] In this embodiment, the housing 110 has an opening at one end and a closed end at the other. In the first state, the bottom of the storage compartment 120 is detachably fixed to the bottom of the housing 110, and the top of the main body 130 is detachably mounted within the storage compartment 120. The charging port 131 is provided at the bottom of the main body 130, with the bottom of the main body 130 facing outward. The bottom of the housing 110 is provided with an elastic clip 111, which can clamp the bottom of the storage compartment 120, so that the storage compartment 120 is clamped to the bottom of the housing 110 in the first state.

[0036] A magnet 132 is provided at the top of the main body 130, and an adsorption portion 121 is provided at the bottom of the storage bin 120. The adsorption portion 121 is preferably a metal pin. In addition, an elastic member 122 is sleeved on the outer side of the adsorption portion 121. One end of the elastic member 122 is fixed to the bottom of the storage bin 120, and the other end is against the top of the main body 130. Preferably, the elastic member 122 is a spring, one end of the spring is fixed to the bottom of the storage bin 120, and the other end is against the top of the main body 130, and is sleeved on the periphery of the magnet 132.

[0037] In another embodiment, the magnet is located at the bottom of the storage compartment, and a metal component that can be attracted by the magnet is provided on the top of the main body.

[0038] In this embodiment, in the first state and the second state, the elastic member 122 is always in a compressed state, that is, the elastic member 122 gives the main body 130 a force toward the outside (that is, the left side in the figure). In the first state, the adsorption portion 121 and the magnet 132 are in an adsorption state. At this time, the magnetic force is the largest, and the main body 130 is fixed to the storage bin 120 under the action of the magnetic force. At the same time, the main body 130 presses the elastic member 122 under the action of the magnetic force to make it in a compressed state.

[0039] The second state corresponds to the compressed state in which the operator presses the storage bin 120 toward the bottom of the housing 110 in the first state to a distance h, i.e., from left to right in the figure. For the housing 110 and the storage bin 120, the elastic buckle 111 enters the release process after the storage bin 120 is pressed. That is, the storage bin 120 will first move to the right relative to the housing 110 by a distance h. Then, when the pressing action ends, the elastic buckle 111 rebounds to the left, thereby driving the storage bin 120 to move leftward and away from the housing 110. h is preferably between 20mm and 220mm. For the storage bin 120 and the main body 130, the storage bin 120 is pressed, causing the adsorption part 121 of the storage bin 120 to move accordingly, so that the adsorption part 121 is separated from the magnet 132, and the magnetic force is greatly reduced. At this time, the movement of the main body 130 compresses the elastic part 122, causing the elastic force to the left side of the main body 130 to be greater than the adsorption force to the right side. The elastic part 122 begins to rebound, and the main body 130 is driven by the rebound of the elastic part 122 to move a distance outward (that is, the left side in the figure).

[0040] It should be noted that, for the electric precision screwdriver 100 as a whole, the operator only presses the storage bin 120, resulting in the storage bin 120 being separated from the shell 110 and popping out a distance to the outside, and the main body 130 being separated from the storage bin 120 and popping out a distance to the outside. In other words, with only one operation, the shell 110, the storage bin 120 and the main body 130 are separated from each other, which greatly increases the ease of operation.

[0041] It should also be noted that the charging port 131 of this embodiment is located at the bottom of the main body 130. If the operator presses the main body 130 directly, they may accidentally touch the charging port 131, thereby shortening its lifespan or affecting the normal operation of the circuit. In addition, the top of the main body 130 is a mounting base that must ensure a tight fit with the screwdriver bit, especially in precision environments. Pressing the main body 130 causes it to first move inward, which in turn drives the storage compartment 120 to a predetermined position, triggering the unlocking process. This can cause significant stress on the top of the screwdriver, which can easily cause deformation and affect the accuracy of the work. Therefore, this embodiment adopts a special method so that pressing the storage compartment 120 simultaneously ejects the main body 130 and separates the housing 110. At the same time, pressing the storage compartment 120 does not add excessive external force to the main body 130 (it only releases its magnetic attraction), which helps maintain the accuracy and lifespan of the electric precision screwdriver 100.

[0042] In another embodiment, the charging port of the main body is opened on the side. At the same time, a channel is left on the side wall of the shell and the storage compartment for the charging cable to be inserted into the charging port, and the shape of the channel corresponds to the shape and size of the charging port. Therefore, when the main body has not been fully stored and reached the predetermined position, the outside world cannot charge the main body through the shell, which can serve as an indicator of whether the main body is fully stored, and can also prevent the main body from being directly charged when it is not fully stored, causing it to fall out of the storage compartment or the main body when touched.

[0043] In another embodiment, the bottom of the shell is provided with a baffle or block that passes through the storage bin. The baffle or block will not hinder the movement of the storage bin. Its function is to prevent the main body from following the movement of the pressed storage bin, thereby ensuring that the magnetic attraction between the main body and the storage bin is reliably destroyed when the storage bin is pressed, thereby realizing the automatic pop-up of the main body.

[0044] The above is a specific description of the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
