Description

Technical Field

[0001] This utility model relates to the field of lithium battery impact wrench technology, and in particular to a lithium battery impact wrench with a replaceable socket. Background Technology

[0002] Lithium-ion battery impact wrenches are widely used in automotive repair, mechanical assembly, and other fields as efficient and portable power tools. Traditional lithium-ion battery impact wrenches typically employ a fixed socket design or use a simple snap-fit ​​mechanism for socket replacement.

[0003] Currently, most lithium-ion impact wrenches on the market use spring balls or snap rings to secure the socket. Their technical principle primarily relies on the compression and reset of the elastic element, causing the ball or snap ring to embed into a groove in the inner wall of the socket, thus forming a mechanical lock. Some designs also incorporate threaded connections or magnetic adsorption to enhance the socket's stability. While these structures meet basic usage requirements, they still have certain limitations in practical applications.

[0004] However, the above-mentioned structure involves cumbersome procedures when frequently changing sockets, requiring users to apply additional force to press or rotate to complete the disassembly, thus extending the operation time and seriously affecting work efficiency. This problem is particularly prominent in work scenarios that require quick switching between different socket sizes, limiting the convenience and practicality of lithium-ion impact wrenches. Therefore, a lithium-ion impact wrench with interchangeable sockets is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lithium-ion impact wrench with a replaceable socket, aiming to improve the problem of prolonged operation time and reduced work efficiency caused by frequent socket changes in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lithium-ion impact wrench with a replaceable socket includes a housing, a handle fixedly connected to the outer wall of the housing, and a snap-fit ​​assembly provided on the side wall of the housing;

[0008] The buckle assembly includes a buckle plate, the side wall of which is fixedly connected to the outer wall of the housing, a sleeve is rotatably connected to the outer wall of the housing, a plurality of first buckle balls are fixedly connected to the inner wall of the sleeve, the side walls of the first buckle balls are rotatably connected to the side wall of the buckle plate, and a locking assembly is provided inside the housing.

[0009] As a further description of the above technical solution:

[0010] The locking assembly includes a limiting post, the outer wall of which is slidably connected to the inside of the housing and the sleeve. A pull ring is fixedly connected to the outer wall of the limiting post, and a baffle is fixedly connected to one end of the limiting post. A spring-loaded assembly is provided on the side wall of the baffle.

[0011] As a further description of the above technical solution:

[0012] The rebound assembly includes a first spring, one end of which is fixedly connected to the side wall of the baffle, and the other end of which is fixedly connected to the inside of the housing. The outer wall of the baffle is slidably connected to the inside of the housing.

[0013] As a further description of the above technical solution:

[0014] A rotating shaft is fixedly connected to the bottom of the outer casing, and a rotating plate is rotatably connected to the side wall of the rotating shaft.

[0015] As a further description of the above technical solution:

[0016] A button is fixedly connected to the bottom of the rotating plate, and a base is fixedly connected to the bottom of the button.

[0017] As a further description of the above technical solution:

[0018] A hollow column is fixedly connected inside the rotating shaft, and a second retaining ball is slidably connected to the inner wall of the hollow column.

[0019] As a further description of the above technical solution:

[0020] The hollow column is equipped with a second spring, both ends of which are fixedly connected to the outer wall of the second ball, and the outer wall of the second ball is slidably connected to the side wall of the rotating plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by pulling the pull ring, the limiting post and the baffle are slid inside the outer shell, and then the outer wall of the limiting post is disengaged from the inside of the sleeve. Subsequently, the sleeve can be rotated to drive the first locking ball to disengage its side wall from the side wall of the locking plate, thus achieving the effect of quick sleeve replacement. This solves the problem of prolonged operation time and reduced work efficiency when frequently changing sleeves, and improves the convenience of the lithium battery impact wrench.

[0023] 2. In this utility model, the base is turned to drive the rotating plate to rotate on the side wall of the rotating shaft. Then, the rotating plate is subjected to force to push the second locking ball on the side wall to squeeze. Then, the second locking ball is subjected to force to push the second spring on the side wall to retract, thus achieving the effect of folding the base. This solves the problem that the long fixed handle hinders operation and affects work efficiency in a narrow space, and improves the practicality of the lithium battery impact wrench.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a lithium-ion impact wrench with a replaceable socket, comprising a housing 2, a handle 3 fixedly connected to the outer wall of the housing 2, and a buckle assembly provided on the side wall of the housing 2.

[0033] The latching assembly includes a latching plate 7, which cooperates with the first locking balls 6 to form a preliminary connection and positioning structure, limiting the sleeve 1 and preventing axial displacement of the sleeve 1 in the unlocked state, thus ensuring the stability of the connection between the sleeve 1 and the outer shell 2. The side wall of the latching plate 7 is fixedly connected to the outer wall of the outer shell 2, and the sleeve 1 is rotatably connected to the outer wall of the outer shell 2. Multiple first locking balls 6 are fixedly connected to the inner wall of the sleeve 1, and the side walls of the first locking balls 6 are rotatably connected to the side wall of the latching plate 7. A locking assembly is provided inside the outer shell 2, including a limiting post 9, which is inserted into the sleeve 1 to form a rigid locking constraint on the sleeve 1, preventing the sleeve 1 from rotating or falling off during operation, thus ensuring safety and stability during operation. The limiting post 9 is slidably connected to the inside of the outer shell 2 and the sleeve 1. A pull ring 8 is fixedly connected to the outer wall of the limiting post 9. A baffle 10 is fixedly connected to one end of the limiting post 9. A spring-loaded assembly is provided on the side wall of the baffle 10. The spring-loaded assembly includes a first spring 11, which provides elastic restoring force. When the limiting post 9 is pulled, it stores elastic potential energy. When the pull ring 8 is released, it releases the potential energy to push the baffle 10 and the limiting post 9 to reset, thereby realizing automatic locking of the sleeve 1 and simplifying the operation steps. One end of the first spring 11 is fixedly connected to the side wall of the baffle 10, and the other end of the first spring 11 is fixedly connected to the inside of the outer shell 2. The outer wall of the baffle 10 is slidably connected to the inside of the outer shell 2.

[0034] Reference Figure 1 , Figure 4 and Figure 5 A rotating shaft 12 is fixedly connected to the bottom of the outer shell 2. A rotating plate 13 is rotatably connected to the side wall of the rotating shaft 12. The rotating plate 13 rotates in conjunction with the rotating shaft 12, causing the base 4 to change its angle. The slot on its side wall cooperates with the second locking ball 14 to fix the angle. It is a key component connecting the rotating shaft 12 and the base 4. A button 5 is fixedly connected to the bottom of the rotating plate 13. The bottom of the button 5 is fixedly connected to the base 4. A hollow column 15 is fixedly connected inside the rotating shaft 12. The second locking ball 14 is slidably connected to the inner wall of the hollow column 15. The second locking ball 14 cooperates with the second spring 16 and the slot of the rotating plate 13 to perform telescopic movement. It is squeezed and contracted when the rotating plate 13 rotates. When it rotates to a suitable angle, it is pushed by the second spring 16 and locked into the slot to achieve the positioning of the rotating plate 13 and ensure the reliability of the fixed angle of the base 4. The second spring 16 is set inside the hollow column 15. Both ends of the second spring 16 are fixedly connected to the outer wall of the second locking ball 14. The outer wall of the second locking ball 14 is slidably connected to the side wall of the rotating plate 13.

[0035] Working principle: When replacing sleeve 1, pulling the pull ring 8 will cause the limiting post 9 to slide along the inside of the outer shell 2. At the same time, the limiting post 9 will cause the baffle 10 to compress the first spring 11. When the outer wall of the limiting post 9 is completely disengaged from the inside of sleeve 1, sleeve 1 loses its locking constraint. At this time, rotating sleeve 1 will cause the first locking ball 6 on its inner wall to slide along the side wall of the locking plate 7 and disengage from the restriction of the locking plate 7, so that the old sleeve 1 can be removed. When replacing the new sleeve 1, the new sleeve 1 is inserted into the outer wall of the outer shell 2, so that the first locking ball 6 is aligned with the side wall of the locking plate 7. After releasing the pull ring 8, the first spring 11 pushes the baffle 10 to reset, causing the limiting post 9 to insert into the inside of the new sleeve 1 to complete the locking. The entire process achieves rapid loading and unloading through the linkage of the mechanical structure, which greatly shortens the replacement time.

[0036] When adjusting the angle of the base 4, turning the base 4 will cause the rotating plate 13 to rotate around the rotating shaft 12. The side wall of the rotating plate 13 presses against the second locking ball 14, causing the second locking ball 14 to slide along the inner wall of the hollow column 15 and compress the second spring 16. When the rotating plate 13 rotates to the appropriate angle, the second spring 16 pushes the second locking ball 14 to reset and lock into the corresponding slot on the side wall of the rotating plate 13 to complete the positioning. This design allows the base 4 to be flexibly adjusted according to the working space. In a confined environment, the folded base 4 can prevent the handle 3 from obstructing operation, while in an open space, the base 4 can be unfolded to ensure grip stability. The cooperation between the second spring 16 and the second locking ball 14 achieves multi-angle fixation, improving the applicability of the tool in different scenarios.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
