[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0024] Figure 1-Figure 3As shown, an electric hammer with APP controllable includes a main body and a first handle 2 and a second handle 3 fixedly connected to the main body. When using the electric hammer, the operator's two hands respectively hold the first handle 2 and the second handle 3, so as to pick up the electric hammer, which is convenient for operating the electric hammer for construction. One end of the first handle 2 and the second handle 3 are connected to the main body through a shock absorbing device 4. The shock absorbing device 4 includes a plurality of shock absorbing columns, which are arranged in a ring with the center point of the handle as the center of the circle. There is a gap between two adjacent shock absorbing columns. A shock absorbing spring 404 located in the gap is sleeved on the outside of each shock absorbing column, and the two ends of the shock absorbing spring 404 are respectively fixedly connected to the body 1 and the first handle 2 / the second handle 3. Therefore, when the electric hammer is started, the motor inside the electric hammer starts to generate vibration. At this time, the force is transmitted to the first handle 2 / the second handle 3 through the shock-absorbing column. During the transmission process, the shock-absorbing spring 404 mounted outside the shock-absorbing column is deformed and shaken due to the force, and the force can be dispersed during the shaking of the shock-absorbing spring 404, thereby reducing the vibration generated when the electric hammer is used and improving the comfort when the electric hammer is used. The shock-absorbing column connects the first handle 2 / the second handle 3 and the body 1, and can prevent the shock-absorbing spring 404 from causing the first handle 2 / the second handle 3 to move when shaking, thereby making the connection between the body 1 and the first handle 2 / the second handle 3 more secure.

[0025] Figure 1 and Figure 2 As shown, the other end of the first handle 2 is connected to the main body via a controller 5, and the controller 5 can be controlled by connecting to an APP via Bluetooth, so that the electric hammer can be remotely controlled, thereby improving the practicality of the electric hammer and making the electric hammer more convenient to use.

[0026] Figure 1-Figure 3 As shown, both ends of the plurality of shock-absorbing columns are commonly connected to a mounting plate 401, the mounting plate 401 is a circular plate, and the two mounting plates 401 are respectively fixedly connected to the main body and the first handle 2 / the second handle 3, and the mounting plates 401 are fixedly connected to the main body and the first handle 2 / the second handle 3 by limiting bolts. Therefore, during installation, the mounting plate 401 is placed between the main body and the first handle 2 / the second handle 3, and the mounting plate 401 is fixed to the main body and the first handle 2 / the second handle 3 by limiting bolts, thereby fixing the plurality of shock-absorbing columns between the main body and the first handle 2 / the second handle 3. This design enables the plurality of shock-absorbing columns to be installed together at one time, thereby making the installation process more convenient and quick, easy to operate, and shortening the installation time.

[0027] Figure 2-Figure 5As shown, a dustproof plate 402 mounted outside the shock absorbing device 4 is fixedly connected between the two mounting plates 401. The dustproof plate 402 is a cylinder. By setting the dustproof plate 402, several shock absorbing columns can be blocked, thereby preventing dust from entering the gap and affecting the internal environment of the shock absorbing device 4. An annular groove 405 is provided on the mounting plate 401. The two ends of the dustproof plate 402 are respectively embedded in the annular grooves 405 of the two mounting plates 401. Therefore, when the electric hammer is used, the annular groove 405 can limit the range of movement of the dustproof plate 402, thereby preventing the dustproof plate 402 from being separated from the two mounting plates 401 due to the vibration of the electric hammer. There is a gap 406 between the dustproof plate 402 and the shock absorbing device 4. The gap 406 reserves a movable space for the shock absorbing spring 404, thereby preventing the shock absorbing spring 404 from colliding with the inner wall of the dustproof plate 402 when shaking, thereby achieving the effect of protecting the shock absorbing spring 404.

[0028] Figure 1-Figure 3 As shown, an elastic pad is fixedly connected to the inner wall of the annular groove 405. When the dustproof plate 402 is inserted into the annular groove 405 and the electric hammer is started, the dustproof pad and the elastic pad form abutment. The vibration generated by the start-up of the electric hammer causes the elastic pad to deform, thereby absorbing part of the force and reducing the force applied to the dustproof plate 402, thereby further reducing the vibration applied to the first handle 2 / the second handle 3.

[0029] Figure 3-Figure 5 As shown, the shock-absorbing column includes a plurality of shock-absorbing pads 403 and a support plate 407 fixedly connected to the shock-absorbing pads 403. The support plate 407 is a steel plate. The shock-absorbing pads 403 are fixedly connected to the mounting plate 401. The support plate 407 and the shock-absorbing pads 403 are staggered. The shock-absorbing pads 403 are elastic. Therefore, when the electric hammer is started, the force generated by the body 1 is first transmitted to the shock-absorbing pads 403 through the mounting plate 401. At this time, the shock-absorbing pads 403 are deformed and absorb part of the force. Thereafter, the remaining force is transmitted to the next layer of support plates 407 through this layer of shock-absorbing pads 403, and then transmitted in sequence, and the force is gradually reduced during the transmission, thereby achieving the effect of reducing the force applied to the first handle 2 / the second handle 3. In addition, by providing the support plate 407, the connection between the main body and the first handle 2 / the second handle 3 can be strengthened to prevent the first handle 2 / the second handle 3 from shaking when the electric hammer is used.

[0030] The above is an introduction to an APP-controllable electric hammer provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
