[0018] Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0019] Embodiment: Please refer to Figures 1-3 , to solve the problem that the impact rod part of the integrated digital display rebound tester in the prior art lacks a protection function, resulting in accidental slipping out of the hand during the use of the integrated digital display rebound tester, causing damage to the impact rod part of the integrated digital display rebound tester during the falling process, and shortening the service life of the integrated digital display rebound tester, this technical solution is designed, and the detailed technical solution is as follows;

[0020] A protective integrated digital display rebound hammer, comprising a rebound hammer body, which is composed of a digital display handle section 1 and a striker rod section 2. An external thread sleeve 3 is fixedly sleeved on the digital display handle section 1, and a protective structure is installed on the external thread sleeve 3;

[0021] It should be noted that the specific structure and working principle of the rebound hammer body composed of the digital display handle section 1 and the striker rod section 2 can refer to the ZBL-S450 model digital display high-strength rebound hammer produced by Beijing Zhibolian Technology Co., Ltd.;

[0022] Specifically, the protective structure includes an internal thread sleeve 4, which is movably sleeved on the external thread sleeve 3. An air ring 5 is fixedly sleeved on the outer side wall surface of the internal thread sleeve 4. A plurality of elastic components are installed on the lower wall surface of the internal thread sleeve 4. The plurality of elastic components are arranged in a circular array centered on the striker rod section 2 on the lower wall surface of the internal thread sleeve 4. A protective ring 6 is installed at one end of the plurality of elastic components;

[0023] It should be noted that the internal thread sleeve 4 is fixedly sleeved on the digital display handle section 1 of the rebound hammer body. The protective structure can be disassembled and assembled through the threaded connection between the internal thread sleeve 4 and the external thread sleeve 3. The plurality of elastic components and the protective ring 6 surround the outside of the digital display handle section 1 of the rebound hammer body to prevent the striker rod section 2 from being knocked by external forces. If the device accidentally slips out of the hand, the plurality of elastic components and the protective ring 6 will protect the striker rod section 2.
