Description

Technical Field

[0001] The utility model relates to the technical field of electric screwdrivers, and particularly relates to a stable electric screwdriver. Background Art

[0002] An electric screwdriver, as an important electric assembly tool, is widely used in industrial production, automobile maintenance, electronic equipment maintenance, home decoration and other fields. Its core function is to quickly tighten and loosen screws through electric drive, greatly improving work efficiency and assembly quality.

[0003] In the prior art, during the use of an electric screwdriver, it is necessary to hold the electric screwdriver by hand to ensure its stable state, and drill holes or turn screws by pushing and pressing the bottom of the electric screwdriver in the advancing direction of the screwdriver bit. However, the hand-held method often cannot maintain the stable operation state of the electric screwdriver when the screwdriver bit rotates, and problems such as unstable feeding, vibration, and jumping often occur. This will cause the screwdriver bit to deviate from the screw, or the drill bit to be unstably stressed and break, and it is easy to produce errors. Often, multiple manual positioning is required to obtain a more accurate result, which seriously affects work efficiency.

[0004] The prior art provides a simple positioning drilling device for an electric screwdriver, which is used to improve the feeding stability of the electric screwdriver and reduce the errors generated during the use of the electric screwdriver. However, this positioning drilling device is installed on the screwdriver in a simple way, resulting in the overall electric screwdriver being relatively bulky, occupying more space, and being inconvenient to carry.

[0027] Embodiment 1

[0028] As Figures 1 to 4 shown, an embodiment of the present application provides a stable electric screwdriver, including: a screwdriver housing 11 provided with a control switch 13 and a screwdriver bit 12, a first housing 2 provided on the screwdriver housing 11, and a second housing 3 rotatably connected to the first housing 2; one end of the second housing 3 is provided with a ball head 31, and the first housing 2 is provided with a ball socket suitable for the ball head 31 to be embedded and rotated; the ball socket and the control switch 13 are arranged on the axis in the length direction of the screwdriver housing 11, and the ball socket and the control switch 13 are arranged on the same side of the screwdriver housing 11; the other end of the second housing 3 is provided with a third housing 4 that can be telescoped along the length direction of the second housing 3; wherein, in the working state, the second housing 3 is located on one side of the screwdriver bit 12, and the third housing 4 is located at one end of the screwdriver bit 12 away from the screwdriver housing 11; in the storage state, the second housing 3 is located on one side of the screwdriver housing 11, and the second housing 3 fits against the screwdriver housing 11 and covers the control switch 13.

[0029] The electric screwdriver is composed of a screwdriver housing 11 and a screwdriver bit 12. The screwdriver bit 12 is arranged at one end of the screwdriver housing 11. The other end of the screwdriver housing 11 is connected to an external power supply through an electric wire, and a control switch 13 for controlling the start and stop of the electric screwdriver is provided on the screwdriver housing 11.

[0030] More preferably, in the embodiments provided in the present application, the first housing 2 is sleeved on one end of the screwdriver housing 11 close to the screwdriver bit 12. A connecting member 21 is provided on the part of the first housing 2 opposite to the control switch 13. The connecting member 21 is provided with a through groove along the length direction of the screwdriver housing 11. Ball sockets are symmetrically provided on the inner wall of the through groove. The second housing 3 is rotatably connected to the first housing 2 by fitting a ball head 31 into the ball sockets. A third housing 4 is provided at one end of the second housing 3 away from the first housing 2. The third housing 4 is connected to the second housing 3 by three telescopic connecting rods 33. Springs 34 are sleeved on the outer sides of the connecting rods 33. The third housing 4 can be telescoped along the length direction of the second housing 3. The third housing 4 has a semi-circular ring structure. During use, when the electric screwdriver is in the storage state, the second housing 3 is stored close to the screwdriver housing 11, and the second housing 3 covers the control switch 13 to prevent accidental touch. When it is necessary to feed the screw, the second housing 3 can be turned over so that the second housing 3 is parallel to the screwdriver bit 12. When feeding the screw, the third housing 4 is attached to the surface of the device to be processed, ensuring that the second housing 3 is parallel to the bolt feeding direction, that is, ensuring the feeding direction of the screwdriver bit 12. Through the telescopic setting of the third housing 4 and the second housing 3, the stable feeding of the screwdriver bit 12 in the screw feeding direction is ensured, and the stability of the screw feeding is improved.

[0031] In this embodiment, by providing the first housing 2 on the screwdriver housing 11, and rotatably connecting the second housing 3 to the first housing 2 through the cooperation of the ball head 31 and the ball sockets, and providing the third housing 4 which can be elastic on the second housing 3, the stability of the electric screwdriver during screw feeding is ensured. At the same time, through the setting of the ball head 31 and the ball sockets, the second housing 3 is turned over and attached to the screwdriver housing 11 for storage, improving the storage portability of the product.

[0032] Embodiment 2

[0033] Further, on the basis of the above embodiment, a control switch protection shell 32 is provided on the second housing 3. When the electric screwdriver is in the storage state, the second housing 3 is attached to the screwdriver housing 11, and the control switch protection shell 32 covers the control switch 13.

[0034] In this embodiment, by providing the control switch protection shell 32 on the second housing 3, and covering the control switch 13 with the control switch protection shell 32, accidental touch of the control switch 13 is avoided, and the use safety of the device is improved.

[0035] Embodiment 3

[0036] Further, on the basis of the above embodiments, two elastic buckles 22 are provided on the connecting member 21. The two elastic buckles 22 face the control switch 13 and the screwdriver bit 12 respectively. During use, the second housing 3 is limited at the screwdriver bit 12 or the screwdriver housing 11 through the elastic buckles 22, so as to prevent the second housing 3 from loosening and causing deviation during use.

[0037] In this embodiment, the second housing 3 is limited by providing the elastic buckles 22 on the connecting member 21, which improves the use stability of the device and at the same time improves the storage and portability of the device.
