Description

Technical Field

[0001] This utility model relates to the field of mechanical tools, and in particular to a socket locking device for an electric wrench. Background Technology

[0002] Electric wrenches, as efficient and convenient power tools, are widely used in construction, machinery, automotive, and power industries. Their main function is to efficiently tighten and loosen bolts, nuts, and other fasteners by providing high torque output, thereby saving time and labor costs. Electric wrenches are particularly suitable for heavy-duty work, ensuring fasteners are properly tightened, avoiding over- or under-tightening torque, and improving work efficiency. Whether in large machinery, lifting equipment, or vehicle assembly operations, electric wrenches, with their powerful torque output and ease of operation, have become the preferred tool for threaded fastener work.

[0003] Existing electric wrenches already possess a certain degree of versatility. They are typically equipped with interchangeable connectors that can adapt to different screw sizes, thus meeting diverse operational needs. Furthermore, some electric wrenches can also be fitted with rotating objects such as drill bits, further expanding the tool's range of applications. This design allows electric wrenches to perform a variety of tasks, improving tool utilization and flexibility. Users can easily adapt to different working environments and operational requirements simply by changing the appropriate connectors or drill bits.

[0004] However, despite the improvements in functionality and flexibility of existing equipment, some significant drawbacks remain during use. The problem of unstable connections is particularly prominent after connector replacement. Because existing small and medium-sized electric wrenches often lack effective tightening mechanisms during connector replacement, the connector is prone to detaching from the wrench during use. This detachment not only affects work efficiency and reduces productivity but also poses potential safety hazards to operators. Utility Model Content

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] This embodiment mainly describes the structure of the electric wrench, as follows:

[0025] A socket locking device for an electric wrench, such as Figures 1-5 As shown, the device includes an electric wrench 1, a connector 2, a pressing plate 3, a limiting ring 31, a sleeve 4, a sleeve rod 5, a first spring 6, a stabilizing component, and a limiting component. The electric wrench 1 is connected to the connector 2 at its front end, and a removable battery is connected to the bottom of the electric wrench 1 to power the rotation of the connector 2. The pressing plate 3 is slidably connected to the upper and lower sides of the front end of the connector 2. The front end of the pressing plate 3 is set as an inclined surface, and the end of the inclined surface transitions smoothly with the front end of the connector 2. The limiting ring 31 is connected to the connector 2 to limit the length of the joint mating with the connector 2. The sleeve 4 is connected to the lower pressing plate 3, and the sleeve rod 5 is slidably connected inside the sleeve 4. The top of the sleeve rod 5 is connected to the pressing plate 3 on the upper side of the connector 2. The first spring 6 is sleeved inside the sleeve 4. One end of the first spring 6 is fixedly connected to the sleeve 4, and the other end is fixedly connected to the sleeve rod 5. The connector 2 is provided with a stabilizing component for stabilizing the position of the pressing plate 3, and the connector 2 is provided with a limiting component for limiting the movement of the stabilizing component.

[0026] like Figure 2 and Figure 4 As shown, the stabilizing component includes a connecting plate 7, a central plate 8, and an operating plate 81. The connecting plate 7 is connected to the adjacent side of the rear ends of the two extrusion plates 3. The front end of the connecting plate 7 is connected to the rear side of the extrusion plate 3, and the rear end extends backward. The central plate 8 is slidably connected inside the connecting head 2. The central plate 8 has a raised middle section and is provided with a flat surface and a slope. The slopes on the upper and lower sides of the central plate 8 are pressed and fitted with the connecting plate 7. The operating plate 81 is connected to the left and right ends of the central plate 8.

[0027] like Figure 3 and Figure 4 As shown, the limiting component includes a locking rod 10, a guide rod 11, and a second spring 12. The upper and lower sides of the character plate 8 have arc-shaped grooves 9. The grooves 9 are located on the raised plane in the middle of the character plate 8. The shape of the grooves 9 is restored to a complete circle. The tangent of the grooves 9 does not pass through the center of the circle. The outer arc of the grooves 9 is smaller than a semicircle. The guide rods 11 are slidably connected to the upper and lower sides of the connector 2. The locking rod 10 is connected to the side adjacent to the guide rod 11. The locking rod 10 is limited to the grooves 9. The shape of the locking plate fits the grooves 9. The second spring 12 is sleeved on the guide rod 11. One end of the second spring 12 is connected to the connector 2, and the other end is connected to the locking rod 10.

[0028] The user places the required connector onto the connector 2, with the inner side of the connector contacting the extrusion plate 3 and the end of the connector contacting the limiting ring 31, thus completing the docking of the connector and the connector 2. Then, the stabilizing component pushes the extrusion plate 3 to move to both sides, engaging with the inner side of the connector to further stabilize the connection. During the movement of the extrusion plate 3, the sleeve rod 5 slides inside the sleeve 4, the first spring 6 is stretched, and the limiting component restricts the stabilizing component, thereby maintaining the state of the extrusion plate 3 and ensuring a stable connection. The user then uses the connector to perform the operation. After the operation is completed, the stabilizing component is moved, the first spring 6 returns to its original position, the two extrusion plates 3 move closer to each other, and then the docking of the connector and the connector 2 is canceled, and the connector is removed.

[0029] When the user pushes the Chinese character plate 8 through the operation panel 81, the inclined surfaces on both sides of the Chinese character plate 8 press and cooperate with the connecting plate 7. During the movement, the connecting plate 7 drives the pressing plate 3 to move, so that the two pressing plates 3 stretch the first spring 6 through the sleeve 4 and the sleeve rod 5 respectively. Moreover, the connecting plate 7 is located inside the connecting head 2 and cannot be separated from the connecting head 2. Consequently, the pressing plate 3 also cannot be separated from the connecting head 2.

[0030] When the groove 9 of the Chinese character plate 8 moves towards the connecting plate 7, the groove 9 also approaches the locking rod 10. The bottom of the locking rod 10 is pressed against the Chinese character plate 8, the guide rod 11 slides upward, and the second spring 12 assembly is compressed. When the locking rod 10 is aligned with the groove 9, the second spring 12 rebounds, pushing the locking rod 10 into the groove 9, thereby limiting the movement of the Chinese character plate 8 and maintaining the pressing state of the Chinese character plate 8 against the connecting plate 7, ensuring the pressing effect of the two pressing plates 3 at the joint. When the user pulls the Chinese character plate 8, the locking rod 10 disengages from the groove 9. At this time, the Chinese character plate 8 disengages from the connecting plate 7. When the pressing plate 3 is not pushed by external force, it is reset by the first spring 6, contacting the pressing of the joint.

[0031] like Figure 5 As shown, it also includes a ball bearing 13. A ball bearing 13 is provided on one side of the two connecting plates 7 that are adjacent to each other. The ball bearing 13 is in rolling connection with the character plate 8. When the character plate 8 and the connecting plate 7 move relative to each other, the ball bearing 13 can reduce the friction between the connecting plate 7 and the character plate 8, so that it is easier for the user to push the character plate 8 and it is more effortless.

[0032] like Figure 4 As shown, it also includes an identification card 14. The top surfaces of the Chinese character plate 8 are connected to the two ends of the identification card 14. The identification card 14 is marked with the effect of the Chinese character plate 8 moving in different directions, namely locking and unlocking, so that users can directly observe and determine the direction of the Chinese character plate 8 being pushed.

[0033] like Figure 4As shown, it also includes a sponge pad 15. The sponge pad 15 is connected to the side of the two control panels 81 that are separated. The user is more comfortable when in contact with the sponge pad 15 than when in contact with the control panels 81. The sponge pad 15 also cushions the pressure, thereby optimizing the operating experience and protecting the user from injury.

[0034] like Figure 3 As shown, it also includes a rubber pad 16. The two extrusion plates 3 are connected to the opposite side of the rubber pad 16 with a textured surface. The raised texture on the surface of the rubber pad 16 can further optimize the fixing effect of the extrusion block to the joint, thereby stabilizing the connection. The front end of the rubber pad 16 and the slope of the extrusion plate 3 are smoothly transitioned.

[0035] like Figure 2 As shown, it also includes a guide block 17. The front end of the connector 2 is connected to the guide block 17. The guide block 17 has beveled surfaces around its perimeter to facilitate the fitting of the connector onto the connector block.

[0036] The user first attaches the connector onto the connector 2, with the inner side of the connector contacting the textured rubber pad 16 on the extrusion plate 3, and the fitting depth is limited by the limiting ring 31. Then, the user pushes the central plate 8 via the operating plate 81. The raised plane and inclined surface of the central plate 8 engage with the connecting plate 7 and the ball bearings 13 on the connecting plate 7, reducing friction and pushing the connecting plate 7, which in turn causes the two extrusion plates 3 to slide along the connector 2, applying pressure to the inner side of the connector for a stable connection. During this process, the sleeve rod 5 slides within the sleeve 4, stretching the first spring 6, which provides continuous extrusion force to the extrusion plates 3. Simultaneously, as the central plate 8 moves, its arc-shaped groove 9 engages with the locking rod 10. When the groove 9 aligns with the locking rod 10, the second spring 12 pushes the locking rod 10 into the groove 9, restricting the movement of the central plate 8 and maintaining stable extrusion of the connector by the extrusion plates 3. The identification card 14 on the top surface of the control plate 8 helps the user clearly understand the pushing direction, while the sponge pads 15 on both sides of the control plate 81 provide a comfortable grip and cushion pressure. After completing the work, by moving the control plate 81 in the opposite direction, the locking lever 10 disengages from the groove 9, the control plate 8 resets, the first spring 6 rebounds, the compression plate 3 resets accordingly, and the connector can be easily removed from the connector 2. The guide block 17 at the front end of the connector 2 facilitates quick and accurate alignment and fitting of the connector onto the connector 2. Through the coordinated action of its components, the entire device achieves efficient locking and convenient unlocking of the sleeve.
