Description

Technical Field

[0001] This utility model relates to the field of electric screwdriver technology, specifically a portable multi-functional electric screwdriver. Background Technology

[0002] A multi-functional electric screwdriver is an intelligent power tool that integrates multiple working modes (such as torque adjustment and forward / reverse switching), is equipped with a variety of accessory interfaces, and supports multiple operations such as quick disassembly / drilling / polishing. It is suitable for precision assembly and maintenance needs under complex working conditions.

[0003] Existing multi-functional electric screwdrivers are too long, resulting in a very large screwdriver storage box and poor portability. Currently, electric screwdrivers and bits are stored separately. If the bits are not carried together with the screwdriver, you need to find the bits before using the screwdriver, which reduces the practicality of the screwdriver.

[0004] Therefore, a portable multi-functional electric screwdriver is needed to improve the above-mentioned problems. Utility Model Content

[0005] To address the problem that existing portable multi-functional electric screwdrivers are too long, resulting in an excessively bulky storage box and poor portability, this invention provides a portable multi-functional electric screwdriver to solve the aforementioned issues.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A portable multi-functional electric screwdriver includes a screwdriver base, a controller mounted on the outer wall of the screwdriver base, a control panel embedded in the outer wall of the controller, a storage component embedded in the outer wall of the screwdriver base, a drive motor mounted on the outer wall of the screwdriver base, a control switch embedded in the outer wall of the screwdriver base, and a folding component mounted on one side of the drive motor and on the outer wall of the screwdriver base.

[0008] As a preferred embodiment of this utility model, the storage component includes a fixing sleeve, which is embedded in the outer wall of the screwdriver base and located on one side of the controller. A limit spring is installed on the inner wall of the fixing sleeve, and a positioning rod is slidably connected to the inner wall of the fixing sleeve. One end of the positioning rod is connected to the limit spring, and an outer shell is installed on one end of the positioning rod.

[0009] As a preferred embodiment of this utility model, a magnetic block is embedded in one side of the positioning rod and on the inner wall of the outer casing. An anti-slip glove is fitted on the outer wall of the outer casing. A storage shell is installed on the outer wall of the fixing sleeve. Storage cavities are arranged in an array on the outer wall of the storage shell. Screwdriver bits are inserted and removed from the inner wall of the storage cavities.

[0010] As a preferred embodiment of this utility model, the storage shell and the outer shell are connected by a sliding connection, and a magnetic sensor is embedded in the top outer wall of the storage shell, wherein the magnetic sensor is located directly below the magnetic block.

[0011] As a preferred embodiment of this utility model, the folding assembly includes a fixing block, which is mounted on the outer wall of the drive motor. A rotating shaft is rotatably connected to the inner wall of the fixing block, and a limit sleeve is rotatably connected to the outer wall of the rotating shaft.

[0012] As a preferred embodiment of this utility model, one end of the limiting sleeve is rotatably connected to an installation block, and a rotating shaft is installed on the inner wall of the installation block opposite to it. One end of the rotating shaft is rotatably connected to a universal flexible shaft bit.

[0013] As a preferred embodiment of this utility model, one end of the universal flexible shaft bit passes through the limiting sleeve and the fixing block in sequence and is connected to the outer wall of the drive shaft of the drive motor, and the other end of the universal flexible shaft bit is equipped with a cross-shaped strong magnetic bit.

[0014] As a preferred embodiment of this utility model, the controller is electrically connected to the control panel, control switch, drive motor and magnetic sensor via wires.

[0015] Compared with existing technologies, this utility model enables the storage of screwdriver bits in a portable multi-functional electric screwdriver by incorporating a storage component. This provides a multi-functional solution. Pulling the outer casing triggers a linkage control mechanism. Its longitudinal movement synchronously drives the positioning rod to slide along the inner wall of the fixed sleeve and stretches the limit spring. Simultaneously, it causes the magnetic block to disengage from the magnetic sensor, triggering an electrical signal to the controller to cut off the power to the drive motor and prevent accidental activation. When the outer casing moves to the storage compartment, the screwdriver bits can be retrieved from the storage cavity to replace the Phillips head magnetic bits. This solves the problem that existing electric screwdrivers and bits are stored separately, requiring users to search for bits before using the screwdriver, leading to poor screwdriver usability.

[0016] This invention enables the folding and storage of screwdriver bits by incorporating a folding component in a portable multi-functional electric screwdriver. By manipulating a limiting sleeve, the limiting sleeve rotates on the outer wall of the rotating shaft, making the limiting sleeve and the drive motor perpendicular to each other. Subsequently, manipulating the universal flexible shaft bit causes it to rotate on the outer wall of the rotating shaft, thus bringing the universal flexible shaft bit into contact with the outer wall of the screwdriver base. The universal flexible shaft bit itself is made of a soft material, allowing for omnidirectional rotation. The folding component limits the folding of the universal flexible shaft bit, making the screwdriver easy to carry. This solves the problem of existing multi-functional electric screwdrivers having excessively long overall lengths, resulting in bulky screwdriver storage boxes and poor portability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figure 1-5 The portable multi-functional electric screwdriver shown includes a screwdriver base 1, a controller 2 mounted on the outer wall of the screwdriver base 1, a control panel 3 embedded in the outer wall of the controller 2, a storage component 4 embedded in the outer wall of the screwdriver base 1, a drive motor 5 mounted on the outer wall of the screwdriver base 1, a control switch 6 embedded in the outer wall of the screwdriver base 1, and a folding component 7 mounted on one side of the drive motor 5 and located on the outer wall of the screwdriver base 1.

[0025] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The storage component 4 includes a fixing sleeve 401, which is embedded in the outer wall of the screwdriver base 1 and located on one side of the controller 2. A limit spring 402 is installed on the inner wall of the fixing sleeve 401, and a positioning rod 403 is slidably connected to the inner wall of the fixing sleeve 401. One end of the positioning rod 403 is connected to the limit spring 402, and an outer shell 404 is installed on one end of the positioning rod 403. A magnet is embedded in one side of the positioning rod 403 and on the inner wall of the outer shell 404. The storage housing 407 is mounted on the outer wall of the magnetic block 405 and the outer shell 404. Storage cavities 408 are arranged in an array on the outer wall of the storage housing 407. Screwdriver bits 409 are inserted and removed from the inner wall of the storage cavity 408. The storage housing 407 and the outer shell 404 are connected by a sliding connection. A magnetic sensor 410 is embedded in the top outer wall of the storage housing 407, and the magnetic sensor 410 is located directly below the magnetic block 405.

[0026] Based on the above structural features and connection relationship, the outer shell 404 drives the magnetic block 405 to move, which causes the magnetic sensor 410 to lose the magnetic attraction of the magnetic block 405. This causes the magnetic sensor 410 to generate an electrical signal that is transmitted to the controller 2 through the wire, thereby causing the controller 2 to control the drive motor 5 to cut off the power to prevent accidental contact when picking up the screwdriver bit 409.

[0027] In this embodiment, specific references Figure 1 , Figure 2 and Figure 3The folding assembly 7 includes a fixing block 701, which is mounted on the outer wall of the drive motor 5. A rotating shaft 702 is rotatably connected to the inner wall of the fixing block 701. A limiting sleeve 703 is rotatably connected to the outer wall of the rotating shaft 702. A mounting block 704 is rotatably connected to one end of the limiting sleeve 703. A rotating shaft 705 is mounted on the inner wall of the mounting block 704. A universal flexible shaft bit 706 is rotatably connected to one end of the rotating shaft 705. One end of the universal flexible shaft bit 706 passes through the limiting sleeve 703 and the fixing block 701 and is connected to the outer wall of the drive shaft of the drive motor 5. A cross-shaped strong magnetic bit 707 is mounted on the other end of the universal flexible shaft bit 706.

[0028] The controller 2 is electrically connected to the control panel 3, control switch 6, drive motor 5 and magnetic sensor 410 via wires, which powers the device and causes the controller 2 to control the operation of the control panel 3, control switch 6, drive motor 5 and magnetic sensor 410.

[0029] When the portable multi-functional electric screwdriver of this solution is working, by turning on the control switch 6, the controller 2 controls the drive motor 5 to run, which causes the drive shaft of the drive motor 5 to rotate the universal flexible shaft bit 706, which in turn causes one end of the universal flexible shaft bit 706 to rotate the Phillips head magnetic bit 707, thus enabling the Phillips head magnetic bit 707 to be used.

[0030] When storing, simply move the limiting sleeve 703 to rotate it on the outer wall of the rotating shaft 702, making the limiting sleeve 703 and the drive motor 5 perpendicular to each other. Then, move the universal flexible shaft bit 706 to rotate it on the outer wall of the rotating shaft 705, making the universal flexible shaft bit 706 fit against the outer wall of the screwdriver base 1. The universal flexible shaft bit 706 itself is made of soft material and can rotate in all directions. The folding component 7 limits the folding of the universal flexible shaft bit 706, thus solving the problem that the existing multi-functional electric screwdrivers have a long overall length, resulting in a very large overall size of the screwdriver storage box and poor portability.

[0031] By pulling the outer casing 404, the positioning rod 403 moves longitudinally, causing it to move longitudinally against the inner wall of the fixed sleeve 401. This stretches the limiting spring 402. Simultaneously, the longitudinal movement of the outer casing 404 moves the magnetic block 405, causing the magnetic sensor 410 to lose its magnetic attraction. This generates an electrical signal that is transmitted to the controller 2 via a wire, thereby instructing the controller 2 to control... The drive motor 5 is powered off to prevent accidental contact when picking up the screwdriver bit 409. When the outer casing 404 moves to the side of the storage casing 407, the screwdriver bit 409 in the inner cavity of the storage chamber 408 can be taken out for use. The screwdriver bit 409 can then be used to replace the Phillips head magnetic bit 707. The storage component 4 makes the screwdriver more functional, thus solving the problem that existing electric screwdrivers and bits are stored separately. If the bits are not carried together with the screwdriver, it is necessary to find the bits before using the screwdriver, which leads to poor screwdriver usability.

[0032] The control panel 3, control switch 6, drive motor 5, magnetic sensor 410, and controller 2 used in this utility model are all existing known electrical devices, and all can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the control panel 3, control switch 6, drive motor 5, magnetic sensor 410, and controller 2 will not be described in detail here.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.
