[0037] Furthermore, in the present invention, both ends of the driving magnetic group are respectively connected to a hammer head mechanism; such a setting can make it possible to knock the parts to be installed at both ends of the shell 1 of the present invention, which is beneficial to improving the scope of application of the present invention. In addition, in the present invention, the hammer head mechanism mainly includes a hammer head body 8. The present invention can realize the knocking and hammering of different parts by setting different hammer head body 8 structures, and then realize the knocking and hammering installation of different parts.

[0038] In addition, it should be noted that the present invention discloses a control system, which includes a control module and an execution module; the control module is connected to the execution module; and a control button is provided, through which a control instruction is input to the control module. After receiving the instruction, the control module performs self-identification and judgment, and issues an instruction to control the action of the execution module to achieve the corresponding design purpose.

[0039] Specific implementation:

[0040] The present invention utilizes a controller to input a pulsed DC voltage to a driving magnetic group, so that the electromagnetic coil 4 generates magnetic force, and the iron core 5 reciprocates in the coil 4, and the two ends of the iron core 5 are connected to a hammer mechanism.

[0041] Depending on the usage scenario, one end of the hammer can hit the door opening rubber strip, and the other end can hit the plastic base.

[0042] The connecting handle 11 is provided with a control display screen and buttons for realizing the display of power, the display of the knocking frequency, the switching of the hammer head mode, and the adjustment of the knocking frequency speed, so as to facilitate the use in various working conditions.

[0043] specific:

[0044] In the present invention, the coil 4 is combined with the frame 3 and installed in the fixed frame 2, and the iron core 5 is required to be connected to the center of the frame 3. At the same time, the two ends of the iron core 5 are required to be connected to the corresponding driving mechanism through the limit spring 6 respectively. The purpose of setting the limit spring 6 is to prevent the iron core 5 from shaking when the electric hammer is taken in a non-working state.

[0045] In addition, the first return spring 9 and the second return spring 10 disclosed in the present invention are inserted on the push column 7 and are respectively located at the inner and outer sides of the housing 1. When the iron core 5 reciprocates, the first return spring 9 and the second return spring 10 can make the hammer head return quickly;

[0046] Meanwhile, in the present invention, the driving battery pack 12 can be a 18650 battery, or of course other types of battery structures, which are fixed in the connecting handle 11 when in use; in subsequent use, the battery and the driving magnetic group can be connected through a wire.

[0047] In addition, in order to facilitate the protection of the hammer body 8, the hammer mechanism in the present invention includes a knocking hammer cover 81 arranged on the outer shell 1; the knocking hammer cover 81 can be fixedly connected to the outer shell 1, or can be detachably connected, and the knocking hammer cover plays a side protection role and also has a guiding role. When in use, the iron core 5 drives the knocking hammer body 8 to extend out of the knocking hammer cover 81, so as to realize functions such as knocking rubber strips.

[0048] As a greater optimization, in the present invention, there are four raised ribs 8-1 on the outer periphery of the striking hammer body 8. In addition, there are four straight grooves 8-2 in the striking hammer cover 81. Through the coordinated use of the raised ribs 8-1 and the straight grooves 8-2, the striking hammer cover 81 can guide the movement of the hammer body 8.

[0049] Similarly, in the present invention, both hammer bodies 8 may be provided with striking hammer covers 81, and of course, striking hammer covers 81 may not be provided as required.

[0050] In the present invention, the striking hammer head cover 81 is connected to the housing by means of interference fit.

[0051] In the specific implementation of the present invention, it is required that one hammer head mechanism has a knocking hammer head cover 81, and the other hammer head mechanism does not have the knocking hammer head cover 81. In other words, the setting of the knocking hammer head cover 81 can be set as needed; the reason why the present invention adopts the above design is that the electric hammer tool disclosed in the present invention is used for knocking and installing door opening rubber strips and plastic screws; setting the knocking hammer head cover will make the hammer head mechanism have a larger size, which is not convenient to extend into the door opening to realize the knocking operation on the door opening rubber strip.

[0052] In addition, as a greater optimization, mounting grooves 51 are respectively provided at both ends of the iron core 5 of the present invention. The arrangement of the mounting grooves 51 plays a good limiting role and facilitates the arrangement of the limit spring 6.

[0053] At the same time, in order to facilitate the fixation of the entire device, in the present invention, the fixing frame 2 is fixedly connected to the inside of the shell; at the same time, a positioning slot can be provided on the outer surface of the fixing frame, and a positioning block can be provided inside the shell. Through the cooperation of the positioning block and the positioning slot, the fixing frame can be locked and fixed inside the shell.

[0054] At the same time, in order to facilitate assembly, in the present invention, the shell can be made into a split structure, that is, the shell is divided into a left shell and a right shell; the left shell and the right shell are connected by a snap buckle. Such a setting can facilitate the assembly operation of the entire electric hammer.

[0055] Of course, in order to ensure integrity, the housing in the present invention may not be made into a split structure, and an opening may be opened on the side of the housing to realize the assembly of various components inside the housing through the opening.

[0056] In addition, as a greater optimization, in the present invention, the hammer body 8 is connected to the end of the pushing column 7 through a threaded portion, a threaded groove 811 is provided at the end of the hammer body 8, and an external thread is provided on the pushing column 7. The hammer body and the pushing column 7 are connected through threads. This connection method not only facilitates the replacement of the hammer body 8, but more importantly, facilitates the assembly of the entire electric hammer; it avoids the problem that the overall design of the hammer body 8 and the pushing column 7 is not easy to pass through the outer shell.

[0057] The assembly sequence of the entire structure of the present invention is mainly divided into two types:

[0058] One is that the shell is a split structure. If it is a split structure, you can first assemble the drive magnetic group, the fixing frame, the pushing mechanism, and the hammer head mechanism, and finally connect the shell to the above-assembled product. This design method is simple to assemble, but the integrity of the shell is slightly worse.

[0059] One is an opening on the side of the housing, through which the components are assembled;

[0060] Based on this background, during the actual assembly:

[0061] First, assemble the coil and the frame, and after assembly, install them into the fixed frame; at the same time, connect the iron core into the frame, and connect limit springs at both ends of the iron core, and then connect the pushing mechanism to the end of the limit spring away from the iron core; it is required that the pushing column is fixedly connected to the limit spring at this time, and at the same time, a second return spring 10 is sleeved on the pushing column; then move the above-mentioned assembled product into the interior of the shell through the opening, so that the pushing columns at both ends extend through the shell to the outside of the shell, and then the first return spring is sleeved on the outside of each pushing column, and the corresponding hammer head body is added.

[0062] In addition, the control system of the present invention includes a controller circuit board 14, which is respectively connected to the battery and the display control board 13, receives information instructions adjusted by the display control board 13, and controls the reciprocating frequency of the iron core 5; the display control board 13 is connected to the controller circuit board 14 to display the battery power and the knocking frequency, and the large and small hammer heads can be switched through the mode button, and the knocking frequency can be adjusted through the speed button.

[0063] Through the arrangement of the above structure, the electric hammer disclosed in the present invention can improve the production efficiency of the assembly line and reduce the hammering workload of the operating staff.

[0064] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
