Specific implementation

[0023] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the utility model.

[0024] Embodiment one

[0025] In conjunction with Figures 1-4 , a building rechargeable electric hammer, including electric hammer body 1, the outer circle of electric hammer body 1 is provided with electric control handle 2 at rear position, the front end of electric hammer body 1 is installed with hammer head 3, the outer circle of electric hammer body 1 is provided with dustproof assembly 4 at front position.

[0026] Refer to Figure 2 and Figure 4 ​Furthermore, the dustproof assembly 4 includes a transparent protective cover 5, a fixing ring 6, and a dust collection bag 11. The transparent protective cover 5 is slidably installed on the front of the outer ring of the electric hammer body 1. The fixing ring 6 is fixedly installed on the center of the outer ring of the electric hammer body 1. An adjusting threaded rod 7 is slidably installed through the front and rear ends of the fixing ring 6 on one side. A sliding rod 10 is fixedly connected through the front and rear ends of the fixing ring 6 on the other side. The front ends of both the adjusting threaded rod 7 and the sliding rod 10 are fixedly connected to the transparent protective cover 5. A mounting plate is fixedly connected to the rear of the outer ring of the adjusting threaded rod 7. The front end of the mounting plate is away from the adjusting threaded rod 7. A tension spring 8 is fixedly installed on one side, and the front end of the tension spring 8 is fixedly connected to the rear end of the fixing ring 6. A dust discharge pipe is provided at the lower position of the outer ring of the transparent protective cover 5, and a threaded seat is provided at the bottom end of the dust discharge pipe. A threaded connector 12 that is compatible with the threaded head is provided at the top end of the dust collection bag 11. The dust collection bag 11 is detachably installed at the bottom end of the dust discharge pipe through the threaded connector 12. The dust collection bag 11 is a soft bag. A dust suction fan 13 is installed inside the dust discharge pipe. A filter plate 14 is provided at the upper position inside the dust discharge pipe. The top end of the filter plate 14 does not exceed the inner wall of the transparent protective cover 5.

[0027] Specifically, when a worker is drilling holes with the electric hammer body 1, the transparent protective cover 5 surrounds the outside of the hammer head 3, which can block most of the dust generated at the hammer head 3, prevent it from flying around and reduce interference with the worker's vision. By activating the filter plate 14, the dust can be guided into the dust collection bag 11 along with the air, so as to collect most of the dust. During use, by turning the limit nut 9 away from the fixing ring 6, the transparent protective cover 5 can slide freely on the electric hammer body 1, preventing the transparent protective cover 5 from causing significant interference to the normal drilling work. The dust collection bag 11 is connected to the dust discharge port through the threaded connector 12, and can be unscrewed and replaced when full.

[0028] Example 2

[0029] See Figure 2 and Figure 3 Furthermore, based on Embodiment 1, the outer ring of the adjusting threaded rod 7 is threaded with limit nuts 9 at both the front and rear ends of the fixed ring 6. The outer ring of the slide rod 10 is provided with a measuring scale that is compatible with the limit nuts 9. The bottom end of the electric control handle 2 is fixedly installed with a battery box 15. A charging port is provided on one side of the battery box 15, and the battery box 15 is electrically connected to the electric hammer body 1 and the vacuum cleaner fan 13.

[0030] Specifically, by screwing the limiting nut 9 to make its opposite surface close to the fixing ring 6, the sliding of the adjusting threaded rod 7 on the fixing ring 6 is limited, thereby limiting the sliding of the transparent protective cover 5 on the electric hammer body 1, at this time, the adjusting scale on the sliding rod 10 can be referred to and adjusted according to the need, so that the transparent protective cover 5 adjusts the opening depth of the hammer head 3, that is, when the electric hammer body 1 is pushed to open the hole, the transparent protective cover 5 contacts the opening surface, so that the hammer head 3 cannot continue to penetrate, but in the process of limiting the opening distance, the transparent protective cover 5 is not pulled into contact with the opening surface by the pulling force of the tension spring 8, so that the dust absorption effect is reduced.

[0031] In actual operation, when the worker holds the electric hammer body 1 to open the hole, most of the dust generated at the hammer head 3 is blocked by the transparent protective cover 5 surrounding the outside of the hammer head 3, preventing it from flying freely and reducing the interference with the line of sight of the personnel, and by starting the filter plate 14, the dust can be guided to enter the dust collecting bag 11 with the air, so as to collect most of the dust, and in use, by screwing the limiting nut 9 away from the fixing ring 6, the transparent protective cover 5 can slide on the electric hammer body 1 at will, preventing the transparent protective cover 5 from causing great interference to the normal opening work, and the dust collecting bag 11 is connected to the dust outlet through the threaded connector 12, so that when it is full, the dust collecting bag 11 can be screwed off for replacement;

[0032] By screwing the limiting nut 9 to make its opposite surface close to the fixing ring 6, the sliding of the adjusting threaded rod 7 on the fixing ring 6 is limited, thereby limiting the sliding of the transparent protective cover 5 on the electric hammer body 1, at this time, the adjusting scale on the sliding rod 10 can be referred to and adjusted according to the need, so that the transparent protective cover 5 adjusts the opening depth of the hammer head 3, that is, when the electric hammer body 1 is pushed to open the hole, the transparent protective cover 5 contacts the opening surface, so that the hammer head 3 cannot continue to penetrate, but in the process of limiting the opening distance, the transparent protective cover 5 is not pulled into contact with the opening surface by the pulling force of the tension spring 8, so that the dust absorption effect is reduced.

[0033] And how the dust collection fan 13 rotates to guide the airflow, and how the electric hammer body 1 controls the hammer head 3 to open the hole, the control components and control modules used are all prior art, and those skilled in the art can realize them without further description, and the content protected by the utility model does not involve improvement of software and power supply.

[0034] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
