[0027] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] Please refer to Figures 1 to 7As shown, the present embodiment provides an impactor for a lithium battery wrench, comprising a first shell 1 and a second shell 2. In order to facilitate holding the impactor, a handle 3 is fixedly installed at the bottom of the first shell 1. A connector 4 for connecting to an output shaft of the lithium battery wrench is rotatably connected to one end of the first shell 1 through a first bearing 5. A transmission rod 6 is rotatably connected to the inside of the first shell 1. A clamp 601 is formed on the upper end of the transmission rod 6. A limited position plug 401 is provided at the lower end of the connector 4. The clamp 601 is slidably plugged into the inside of the limited position plug 401. The connector 4 can drive the transmission rod 6 to rotate. A first transmission ring 13 is clamped inside the first shell 1, wherein the outer wall of the first transmission ring 13 is fixedly connected to a limited position protrusion 1301. The inside of the first shell 1 is opened. A slot 101 is provided, and a limiting protrusion 1301 is clamped in the slot 101. A second transmission ring 14 is fixedly sleeved on the transmission rod 6. A step tooth groove is provided on the side adjacent to the first transmission ring 13 and the second transmission ring 14. After the rotating second transmission ring 14 contacts the first transmission ring 13, it can drive the transmission rod 6 to move downward under the extrusion of the step tooth groove. The interior of the second shell 2 is rotatably connected with a transmission sleeve 7 through a second bearing 10. The end of the transmission rod 6 away from the first shell 1 is inserted into the interior of the transmission sleeve 7. A locking assembly for limiting the transmission rod 6 inside the transmission sleeve 7 is provided on the transmission sleeve 7. The transmission rod 6 can drive the transmission sleeve 7 to rotate and move through the locking assembly. One end of the impact head is connected to the end of the transmission sleeve 7 away from the transmission rod 6.

[0029] By adopting the above technical solution, when in use, the output shaft of the lithium-ion wrench is connected to the connecting head 4, and then the impact head used for impact is connected to the lower end of the transmission sleeve 7, and then the impact head is pressed against the position where a hole needs to be punched, and then the lithium-ion wrench is started. At this time, the rotating connecting head 4 drives the transmission rod 6 to rotate, and the transmission rod 6 drives the impact head to rotate through the transmission sleeve 7. Because the impact head is squeezed, the transmission rod 6 is driven to move toward the connecting head 4 through the transmission sleeve 7, so that the first transmission ring 13 and the second transmission ring 14 are in contact, and the transmission rod 6 is driven to move downward under the squeezing of the step tooth groove, and the downward-moving transmission rod 6 drives the impact head to move downward through the transmission sleeve 7, so that the impact head can achieve continuous rotation and knocking actions.

[0030] Specifically, the locking assembly includes a card bead 9 and a limiting ring 8. A limiting groove 602 is provided at the lower end of the transmission rod 6, and a sliding hole 701 is provided at the upper end of the transmission sleeve 7. The card bead 9 is arranged in the sliding hole 701, and a part of the card bead 9 is stuck in the limiting groove 602. The limiting ring 8 is sleeved on the transmission sleeve 7. The limiting ring 8 can limit the card bead 9 in the sliding hole 701, and the setting of the limiting ring 8 can effectively prevent the card bead 9 from falling off from the sliding hole 701. An annular pad 12 is provided at the upper end of the second bearing 10, and a second spring 11 is sleeved on the transmission sleeve 7. The lower end of the second spring 11 is pressed on the annular pad 12, and the upper end of the second spring 11 is against the lower surface of the limiting ring 8. The upper end of the limiting ring 8 is in contact with the upper end of the transmission sleeve 7. The setting of the second spring 11 can form an extrusion force on the limiting ring 8 to prevent the limiting ring 8 from slipping off the card bead 9.
