[0002] The hammer seat body is a device for fixing and positioning the hammer, usually applied in various mechanical and electronic devices. Its main function is to ensure that the hammer can accurately hit the target, thereby improving the working efficiency and precision of the device.

[0003] The prior art patent publication No. CN214519974U discloses a nail shooter hammer and hammer seat body mounting and fixing structure, which includes a hammer seat body, a spring retainer and a hammer. The hammer seat body includes a hammer seat body main body, which is fixedly connected with a first shaft column and a connecting column at both ends respectively. A placing groove is coaxially formed on the outer end of the connecting column, and a retainer groove is formed on the inner wall of the placing groove. The hammer seat body main body is provided with a second shaft column, and a horizontal hole is formed through the center of the second shaft column. A taper groove is formed on the outer wall of the hammer seat body main body. The utility model sets the placing groove on the outer end of the connecting column, and sets the retainer groove in the placing groove. The hammer seat is placed in the placing groove, and the spring retainer is placed in the retainer groove. The inner wall of the spring retainer tightly fits the taper surface of the hammer seat, which fixes the hammer in the placing groove, avoiding the use of fixing pins to fix the hammer in the placing groove. Therefore, the hammer and the hammer seat body do not need to be punched during production, thereby reducing the rate of defective products and improving production efficiency.
