[0012] The utility model has the following beneficial effects:

[0013] In the utility model, the displacement of the stamping ring can cause the sleeve to be displaced, thereby causing the spring to be compressed and rebound. At this time, the elastic force of the spring can be used to improve the stamping resistance and rebound ability of the batch head during use. At the same time, the friction force can be increased to prevent thread slippage and unstable docking, thereby effectively improving the practicality and durability of the batch head.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1 - Figure 3The utility model provides an embodiment: a stamping-resistant rebound batch head, including a connecting rod 1, the connecting rod 1 is made of high-strength bearing steel, and its dimensional accuracy and structural stability are ensured by precision machining, so as to maintain high strength and durability during the entire stamping process, the outer bottom side of the connecting rod 1 is fixedly connected with a fixed frame 2, the design of the fixed frame is to provide a stable support frame for other moving parts, the inner top side of the fixed frame 2 is fixedly connected with a plurality of sliding sleeves 3, the outer sides of the plurality of sliding sleeves 3 are all slidably connected with sleeves 4, the function of the sliding sleeves 3 is to provide a sliding path for the sleeves 4 The sleeve 4 has a diameter, so that the sleeve 4 can move in a specific direction when subjected to force while maintaining the linearity and stability of the movement. A spring 5 is arranged inside each of the multiple sleeves 4. One end of the spring 5 is fixedly connected to the internal top side of the sliding sleeve 3, and the other end of the spring 5 is fixedly connected to the internal bottom side of the sleeve 4. The sleeve 4 can compress the spring 5 when subjected to external force, and is pushed to reset by the spring 5 after the external force is removed to achieve a rebound function. The spring 5 provides power by storing and releasing energy to help the screwdriver bit return to its initial position after the stamping operation. The high elasticity and fatigue resistance of the spring 5 ensure the long-term stability of the screwdriver bit. In use, the interiors of multiple sleeves 4 are all slidably connected to limit rings 6, and the interiors of multiple sleeves 4 are provided with limit grooves 7. The exteriors of the limit rings 6 are slidably connected to the interiors of the limit grooves 7. The limit rings 6 are used to control the movement range of the sleeves 4 to prevent the sleeves 4 from completely escaping from the sliding sleeves 3, thereby playing a role of safety restriction. The bottoms of the multiple sleeves 4 are fixedly connected to stamping rings 8, and the interiors of the stamping rings 8 are slidably connected to the exteriors of the connecting rods 1, and the exteriors of the stamping rings 8 are slidably connected to the interiors of the fixed frames 2. The stamping rings 8 are used to directly contact the workpiece during the stamping process to transfer and evenly distribute the stamping pressure. The bottom of the connecting rod 1 is fixedly connected with a docking joint 9, which is made of S2 tool steel. The outside of the docking joint 9 is provided with an anti-skid groove 10. The docking joint 9 is made of S2 tool steel and has sufficient strength and wear resistance. The external anti-skid groove 10 increases the gripping force to prevent sliding during high-load operations. The top of the connecting rod 1 is provided with a connecting assembly, which includes a connecting column 11. The top of the connecting column 11 is fixedly connected with a mounting column 12. The materials of the connecting rod 1, the connecting column 11 and the mounting column 12 are all bearing steel, and they are all made of wear-resistant bearing steel. The design of the connecting assembly allows the screwdriver bit to be easily installed on the drive device, such as an electric or pneumatic screwdriver, and ensures the force transmission efficiency and the stability of the screwdriver bit.

[0022] Working principle: When it is necessary to use this batch head, first, the batch head can be installed and fixed on the electric or pneumatic screwdriver with the help of the mounting column 12 and the connecting column 11, and then the anti-skid groove 10 can be aligned to the screw to be tightened or loosened, and the docking head 9 will slide in and align to the top of the screw. As the screw is aligned, the stamping ring 8 will be squeezed and displaced upward, and then the sleeve 4 will be displaced and slide on the outside of the sliding sleeve 3. At this time, the spring 5 will be compressed and rebounded, and then the alignment and stamping process will be more stable. At this time, with the help of the elastic force of the spring 5, the batch head can be stably rebounded, and then its service life can be extended. With the help of the anti-skid groove 10 on the outside of the docking head 9, the friction at the docking point can be increased and more stable. At the same time, the material of the docking head 9 is S2 tool steel, which has excellent strength and toughness, so that it can better adapt to stamping and rebound, and thus extend its service life.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
