Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Example 1:

[0027] A high-strength electric hammer, such as Figures 1-4 As shown, the device includes an electric hammer body 1. An auxiliary mechanism 2 is threadedly connected to the front side of the electric hammer body 1. The auxiliary mechanism 2 includes a mounting bracket 201. A sealing plug 202 is fixedly connected to one side of the mounting bracket 201. A sliding sleeve 203 is slidably connected to the sealing plug 202. An elastic connector 3 is provided on the top of the sliding sleeve 203. A handle 204 is fixedly connected to one side of the elastic connector 3. Considering the convenience and safety of operation, the device allows users to control the electric hammer more easily during use and improves work efficiency.

[0028] See Figure 3 and Figure 4 The elastic connector 3 includes an upper connecting block 301 and a lower connecting block 302. The upper connecting block 301 and the lower connecting block 302 are combined by a shock-absorbing rubber block 303. By transforming the rigid connection into a multi-level flexible connection, vibration is reduced, the durability of the electric hammer is enhanced, and the service life is extended.

[0029] See Figure 3 and Figure 4 The upper connecting block 301 and the handle 204 are threaded together, and the lower connecting block 302 and the sliding sleeve 203 are threaded together. The threaded connection has good sealing performance and is easy to disassemble. By adding a sealing gasket, the sealing effect can be further improved, and it provides great convenience for users when maintaining the electric hammer.

[0030] See Figure 2 , Figure 3 and Figure 4 A sealing ring 205 is fitted on the outer side of the sealing plug 202. A gap 4 is provided between the sealing plug 202 and the lower connecting block 302. The gap 4 between the sealing plug and the lower connecting block allows the electric hammer to generate a certain amount of air pressure buffer during operation, further reducing the impact of vibration on the user, and at the same time providing force for subsequent rebound.

[0031] See Figure 1 , Figure 2 , Figure 3 An extension rod 101 is provided on the top of the electric hammer body 1. A switch 102 is provided at one end of the extension rod 101. The switch 102 at one end of the extension rod allows the user to easily control the start and stop of the electric hammer, enhancing the ease of use.

[0032] See Figure 1 , Figure 2 , Figure 3 A protective cover 103 is provided on one side of the electric hammer body 1. The protective cover 103 has heat dissipation holes 104. The heat dissipation holes 104 on the protective cover ensure that the electric hammer can effectively dissipate heat during operation, prevent overheating and damage to the equipment, and extend the service life of the electric hammer.

[0033] The implementation principle of this utility model is as follows: First, the electric hammer body 1 is fixed with an auxiliary mechanism 2 by a threaded connection. A sealing ring 205 is sleeved on the outside of the sealing plug 202 to ensure the sealing during the sliding process. The elastic connecting piece 3 is connected to the handle 204 and the sliding sleeve 203 by threads to form a flexible connection.

[0034] When the electric hammer body 1 starts working, driven by the internal motor, the electric hammer body 1 will move up and down, causing the sealing plug 202 to slide inside the sliding sleeve 203. Since there is a gap 4 between the sealing plug 202 and the sliding sleeve 203, when the sealing plug 202 moves, it will compress the air, which will play a buffering role. The compressed air can accumulate potential energy and strengthen the subsequent impact force.

[0035] Meanwhile, the shock-absorbing rubber block 303 in the elastic connector 3 can absorb and reduce vibrations in other directions, allowing the originally rigidly connected handle part to better adapt to the vibration of the electric hammer body and avoid the risk of metal fatigue fracture.

[0036] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
