Description

Technical Field

[0001] This utility model belongs to the field of anti-detachment structure technology, and in particular relates to a portable electric wrench with an anti-detachment structure. Background Technology

[0002] An electric wrench is a common power tool mainly used for tightening or loosening various bolts and nuts. It is powered by a built-in motor, which can greatly save manpower and improve work efficiency compared to traditional manual wrenches. Its working principle is to use the motor to drive the transmission device to convert electrical energy into mechanical energy, which in turn drives the wrench head to rotate. Electric wrenches usually have an adjustable torque function, which can accurately set the torque according to different work needs, effectively avoiding problems such as bolt damage or loosening due to excessive torque.

[0003] Generally, after inserting a hex bolt into an electric wrench, the worker is usually required to hold the hex bolt with one hand and grip the electric wrench with the other. Then, by rotating the electric wrench, the hex bolt is screwed into the object. However, this method often has certain drawbacks. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides: a portable electric wrench with an anti-detachment structure, including a handle, and a main body is installed on the upper side of the handle;

[0005] A first rotating shaft is installed inside the main body, a first cavity is opened inside the first rotating shaft, and a second rotating shaft is slidably connected inside the first cavity;

[0006] A bearing clamping plate is installed at one end of the second rotating shaft;

[0007] The front end of the main body is equipped with an anti-detachment component.

[0008] As a preferred embodiment of the present invention, the anti-detachment component includes a limiting block fixedly connected to the second rotating shaft;

[0009] A spring is installed on one side of the limiting block, and the other end of the spring is fixedly connected to the inner wall of the first cavity.

[0010] An inductive switch capable of contacting the limiting block is installed on the inner wall of the first cavity.

[0011] As a preferred embodiment of the present invention, a first electromagnetic block capable of contacting a hexagonal screw is installed inside the bearing clamping plate;

[0012] The first electromagnetic block is hexagonal;

[0013] One end of the second rotating shaft is equipped with a second electromagnetic block that can contact the bearing clamping plate. Both the first electromagnetic block and the second electromagnetic block are electrically connected to the inductive switch.

[0014] As a preferred embodiment of this utility model, an annular baffle is installed at the front end of the main body, and an elastic sheet is installed on the inner wall of the annular baffle.

[0015] As a preferred embodiment of the present invention, the bearing clamping plate is provided with an annular groove;

[0016] A drive wheel that can contact the elastic sheet is rotatably connected inside the annular groove.

[0017] As a preferred embodiment of this utility model, the bearing clamping plate is provided with a first threaded hole, and a first bolt that can contact the first electromagnetic block is connected in the first threaded hole by a thread.

[0018] As a preferred embodiment of this invention, the back of the bearing clamping plate is made of metal, and the annular baffle is made of transparent material.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] When installing hexagonal bolts, the operator places the bolt into the bearing clamping plate. Once the bolt is in place, the operator pushes the second rotating shaft to slide within the first cavity. After the second rotating shaft reaches the preset position, the anti-loosening component secures the hexagonal bolt, preventing it from falling off. Then, the operator holds the handle and drives the main body to rotate the first and second rotating shafts together, allowing the hexagonal bolt to be screwed into the target object. The anti-loosening component effectively prevents the bolt from falling off during installation, thereby reducing wasted time and potential injury risks. Attached Figure Description

Detailed Implementation

[0027] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0028] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Please see Figures 1 to 5 This utility model provides a portable electric wrench with an anti-detachment structure, including a handle 1, a main body 2 mounted on the upper side of the handle 1; a first rotating shaft 3 mounted inside the main body 2, a first cavity 4 opened inside the first rotating shaft 3, and a second rotating shaft 6 slidably connected inside the first cavity 4; a bearing clamping plate 7 mounted on one end of the second rotating shaft 6; and an anti-detachment component mounted on the front end of the main body 2.

[0030] Using the above solution: When it is necessary to drive the hexagonal bolt into other objects, firstly, the worker places the hexagonal bolt into the bearing clamping plate 7. After the hexagonal bolt is placed, it is pushed to move, thereby pushing the second rotating shaft 6 to slide in the first cavity 4. When the second rotating shaft 6 moves to the preset position, the anti-loosening component clamps the hexagonal bolt to prevent it from falling. Then, the worker holds the handle 1 and drives the main body 2 to rotate the first rotating shaft 3 and the second rotating shaft 6 together, thereby screwing the hexagonal bolt into the target object. By using the anti-loosening component, the problem of hexagonal bolts falling during installation can be effectively avoided, thereby reducing the waste of time and the risk of possible damage caused by hexagonal bolts falling.

[0031] Furthermore, the anti-detachment component includes a limiting block 8 fixedly connected to the second rotating shaft 6; a spring 9 is installed on one side of the limiting block 8, and the other end of the spring 9 is fixedly connected to the inner wall of the first cavity 4; an induction switch 10 that can contact the limiting block 8 is installed on the inner wall of the first cavity 4.

[0032] Furthermore, a first electromagnetic block 11 capable of contacting a hexagonal screw is installed inside the bearing clamping plate 7; the first electromagnetic block 11 is hexagonal; a second electromagnetic block 12 capable of contacting the bearing clamping plate 7 is installed at one end of the second rotating shaft 6, and the first electromagnetic block 11 and the second electromagnetic block 12 are both electrically connected to the inductive switch 10.

[0033] Furthermore, an annular baffle 13 is installed at the front end of the main body 2, and an elastic sheet 14 is installed on the inner wall of the annular baffle 13.

[0034] Furthermore, an annular groove 15 is provided on the bearing clamping disk 7; a drive wheel 16 that can contact the elastic sheet 14 is rotatably connected in the annular groove 15.

[0035] The above scheme is adopted as follows: During use, the hexagonal bolt is manually placed into the first electromagnetic block 11, and then the hexagonal bolt is pushed to move it, which pushes the second rotating shaft 6 to slide in the first cavity 4. During the movement of the second rotating shaft 6, the limiting block 8 moves synchronously, and the limiting block 8 compresses the spring 9. When the limiting block 8 reaches the preset position, the back of the bearing clamping plate 7 is attached to the second electromagnetic block 12, and the limiting block 8 contacts the induction switch 10. After triggering, the first electromagnetic block 11 and the second electromagnetic block 12 are energized. The first electromagnetic block 11 attracts the hexagonal bolt to prevent it from falling, and the second electromagnetic block 12 attracts the back of the bearing clamping plate 7 to prevent the second rotating shaft 6 from moving. Then, the main body 2 drives the first rotating shaft 3 and the second rotating shaft 6 to rotate, screwing the hexagonal bolt into the designated object. During the rotation, the drive wheel 16 on the bearing clamping plate 7 continuously contacts the elastic plate 14, so that the bearing clamping plate 7 will not shake or tilt when rotating, further ensuring the stability during the installation process, reducing shaking and tilting, and thus improving the installation quality of the hexagonal bolt.

[0036] It should be noted that after the hexagonal bolts are installed, the induction switch 10 is turned off by the control terminal. At this time, the first electromagnetic block 11 and the second electromagnetic block 12 are de-energized, causing the hexagonal bolts to disengage from the bearing clamping plate 7. At the same time, the elasticity of the spring 9 pushes the limit block 8 in the opposite direction, causing the second rotating shaft 6 to gradually move away from the induction switch 10.

[0037] Furthermore, the bearing clamping disk 7 is provided with a first threaded hole 17, and a first bolt 18 that can contact the first electromagnetic block 11 is connected in the first threaded hole 17 by a thread.

[0038] Using the above scheme: When using it, in the process of screwing the hexagonal bolt into the designated object, it is first necessary to select a suitable first electromagnetic block 11 according to the diameter of the hexagonal bolt, so that the size of the first electromagnetic block 11 matches the size of the hexagonal bolt. After selection, the first electromagnetic block 11 is placed in the bearing clamping plate 7, and then the first bolt 18 is inserted into the first threaded hole 17. As one end of the first bolt 18 gradually presses against the first electromagnetic block 11, the first electromagnetic block 11 is fixed, thereby facilitating the installation process.

[0039] Furthermore, the back of the bearing clamping plate 7 is made of metal, and the annular baffle 13 is made of transparent material.

[0040] The working principle of this utility model:

[0041] When a hex bolt needs to be driven into another object, firstly, a worker places the hex bolt into the bearing clamping plate 7. After the hex bolt is placed, it is manually placed into the first electromagnetic block 11. Then, the hex bolt is pushed to move, causing the second rotating shaft 6 to slide within the first cavity 4. During the movement, the second rotating shaft 6 drives the limiting block 8 to move synchronously, compressing the spring 9. When the limiting block 8 reaches the preset position, the back of the bearing clamping plate 7 contacts the second electromagnetic block 12, and the limiting block 8 contacts the induction switch 10, triggering the first electromagnetic block 11. When the magnetic block 11 and the second electromagnetic block 12 are energized, the first electromagnetic block 11 attracts the hexagonal bolt to prevent it from falling off, and the second electromagnetic block 12 attracts the back of the bearing clamping plate 7 to prevent the second rotating shaft 6 from shifting. Then, the main body 2 drives the first rotating shaft 3 and the second rotating shaft 6 to rotate, screwing the hexagonal bolt into the designated object. During the rotation, the drive wheel 16 on the bearing clamping plate 7 continuously contacts the elastic plate 14, so that the bearing clamping plate 7 will not shake or tilt when rotating, further ensuring the stability during the installation process, reducing shaking and tilting, thereby improving the installation quality of the hexagonal bolt.
