[0001] This utility model relates to the field of power tool technology, and in particular to a power tool. Background Technology

[0002] Power tools are tools powered by electricity or batteries, including but not limited to electric drills, electric screwdrivers, and electric wrenches. When using power tools, operators may need to strike workpieces, such as bolts or fasteners. To save time, operators sometimes directly strike the workpiece with the rear end face of the power tool's housing. Since the housing of power tools is usually made of plastic, directly striking the workpiece with the housing can easily lead to severe wear and even deformation of the rear end face of the housing, ultimately causing the motor to scrape against metal.

[0003] Some existing power tools have a metal striking plate added to the rear of the housing, which the operator can use to strike the workpiece. If the power tool has a bit, when the power tool is turned upside down to strike the workpiece, the bit is facing the operator, which poses a certain safety hazard. Utility Model Content

[0004] Based on the aforementioned deficiencies in the existing technology, the purpose of this utility model is to provide an electric tool that, by adding a hammering structure with higher structural strength to the tool body, can be used to hammer workpieces laterally or axially, making it less likely to injure the operator and ensuring safe operation.

Therefore, a feature specified as "first" or "second" can explicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two; "several" means at least one; unless otherwise expressly defined.

[0041] In this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "linking," "fixing," and "setting," etc., should be interpreted broadly.

[0043] In this utility model, "front," "rear," "left," "right," "up," and "down" all refer to... Figure 1 , Figure 2 ... Figure 6 and Figure 7 The markings in the text shall prevail.

[0044] The following is based on Figures 1 to 8 This utility model describes the power tool in detail.

[0045] In this embodiment, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the power tool 100 includes a tool body 1 and a striking structure 2. The tool body 1 includes a housing 11 and a motor, a reduction mechanism, a transmission mechanism (not shown in the figure), and an output shaft 12 located in the housing 11. The tool head (such as a screwdriver bit, drill bit, or screwdriver) is mounted on the output shaft 12. The rotational driving force output by the motor is reduced by the reduction mechanism and then transmitted to the transmission mechanism. The transmission mechanism outputs power to the tool head through the output shaft 12 to drive the tool head to work.

[0046] The structural strength of the striking structure 2 is greater than that of the casing 11, such as Figure 5 and Figure 8As shown, the striking structure 2 includes a first striking part 21 and a second striking part 22 connected together. The first striking part 21 is located on the side of the tool body 1, and the second striking part 22 is located at the rear of the tool body 1. The striking structure 2 also includes a first mounting part 23, which is located on the side of the tool body 1, for connecting the first striking part 21 to the tool body 1, thereby assembling the striking structure 2 onto the tool body 1.

[0047] In the above technical solution, a stronger striking structure 2 is added to the tool body 1. The striking structure 2 includes a first striking part 21 and a second striking part 22. The first striking part 21 allows the power tool 100 to strike the workpiece laterally, and the second striking part 22 allows the power tool 100 to strike the workpiece axially. This avoids the operator directly striking the workpiece with the tool body 1, preventing deformation of the tool body 1. Furthermore, when the tool head is not removed, if the operator needs to strike the workpiece with the power tool 100, the operator can strike the workpiece using the first striking part 21. This prevents the tool head from pointing directly at the operator, reducing safety hazards and avoiding accidental injury. When the tool head is removed, if the operator needs to strike the workpiece with the power tool 100, the operator can strike the workpiece using either the first striking part 21 or the second striking part 22. The operator can choose between lateral or axial striking based on ease of operation, thus enriching the functionality. Furthermore, the striking structure 2 is connected to the tool body 1 via the first mounting part 23, which can improve the stability of the first striking part 21, and thus improve the stability of lateral striking.

[0048] It should be understood that "axial striking" in this article refers to striking along the extension direction of the rotation center axis of the output shaft 12. The front-back direction in this article refers to the orientation of the power tool 100 when it is in operation, that is, the direction in which the output shaft 12 of the power tool 100 faces the workpiece is front, and the direction in which the output shaft 12 faces away from the workpiece is rear.

[0049] In one implementation, such as Figure 1 , Figure 5 , Figure 6 and Figure 8 As shown, there are two first striking parts 21, each connected to a second striking part 22. The two first striking parts 21 are located on the left and right sides of the tool body 1, respectively. The user can choose to use the first striking part 21 located on the left side of the tool body 1 or the first striking part 21 located on the right side of the tool body 1 to strike the workpiece. Furthermore, the first striking parts 21 on both sides can clamp and hold the tool body 1, thereby improving the stability of the connection between the striking structure 2 and the tool body 1. Specifically, as... Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the housing 11 includes a connected main body housing 111 and a handle housing 112. The motor, reduction mechanism, and transmission mechanism are respectively housed in the main body housing 111. The handle housing 112 is located below the main body housing 111. The operator picks up the power tool 100 by holding the handle housing 112. In this design, when it is necessary to strike the workpiece from the side, the user only needs to hold the handle housing 112 vertically and face the left or right side of the main body housing 111 towards themselves to strike, which is convenient to operate. Of course, the number of first striking parts 21 is not limited to two; it can also be three, four, or even more. Of course, the first striking part 21 can also be a ring-shaped integral structure, with the first striking part 21 wrapping around the main body housing 111 circumferentially.

[0050] In one implementation, such as Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the first mounting part 23 is connected to the housing 11. The housing 11 is made of plastic, and the modification cost is relatively low. Adding a mounting structure on the housing 11 that is compatible with the first mounting part 23 is beneficial for controlling processing costs. Of course, the first mounting part 23 can also be connected to other components located inside the housing 11.

[0051] In one implementation, such as Figure 1 and Figure 6 As shown, the first striking part 21 at least partially abuts against the side wall of the housing 11 to increase the structural stability of the first striking part 21 and avoid or reduce the shaking of the first striking part 21 during the striking of the workpiece. Preferably, the side wall of the first striking part 21 facing the housing 11 can completely abut against the side wall of the housing 11. The second striking part 22 at least partially abuts against the rear wall of the housing 11 to increase the structural stability of the second striking part 22 and avoid or reduce the shaking of the second striking part 22 during the striking of the workpiece. Preferably, the side wall of the second striking part 22 facing the housing 11 can completely abut against the rear wall of the housing 11.

[0052] Furthermore, such as Figure 1 and Figure 6 As shown, in order to increase the contact area between the second striking part 22 and the housing 11, the circumferential contour of the second striking part 22 is made as consistent as possible with the circumferential contour and size of the rear end face of the housing 11.

[0053] In one embodiment, the striking structure 2 is a metal part with high structural strength and is not easily deformed.

[0054] In one embodiment, the connection between the first mounting part 23 and the tool body 1 includes fastener (such as screw) connection, plug-in or snap-fit, which facilitates assembly.

[0055] First Implementation Method

[0056] The following is based on Figures 1 to 5 This invention describes in detail the electric tool according to the first embodiment of the present invention.

[0057] In this embodiment, such as Figure 1 , Figure 3 and Figure 5 As shown, the first mounting part 23 is a mounting hole, and the first mounting part 23 is connected to the tool body 1 by the first screw 3, which makes assembly simple.

[0058] In one implementation, such as Figure 1 , Figure 3 and Figure 5 As shown, the striking structure 2 also includes an annular connecting structure 24, which is sleeved on the outer periphery of the tool body 1. The front end of the first striking part 21 is connected to the annular connecting structure 24, and the rear end of the first striking part 21 is connected to the second striking part 22. The first mounting part 23 is provided on the annular connecting structure 24, and the number of the first mounting parts 23 is four. Preferably, in order to ensure the stability of the connection between the annular connecting structure 24 and the tool body 1, the four first mounting parts 23 are evenly spaced along the annular connecting structure 24. Of course, the number of first mounting parts 23 is not limited to four; it can also be two, three, or even more. In this solution, by sleeved with the tool body 1 through the annular connecting structure 24, the stability of the connection between the first striking part 21 and the tool body 1 can be improved. Furthermore, by opening a hole in the annular connecting structure 24 instead of directly opening a hole in the first striking part 21, the structural strength of the first striking part 21 can be avoided from being reduced due to the opening.

[0059] In one implementation, such as Figure 1 , Figure 4 and Figure 5 As shown, the striking structure 2 also includes a second mounting portion 25, which is disposed on the second striking portion 22 and is used to connect the second striking portion 22 to the tool body 1. In this design, the first striking portion 21 and the second striking portion 22 are respectively connected to the tool body 1, which can reduce or avoid the shaking of the first striking portion 21 or the second striking portion 22 during the striking of the workpiece. Preferably, in order to control processing costs, the second mounting portion 25 is connected to the housing 11.

[0060] Furthermore, such as Figure 1 , Figure 4 and Figure 5As shown, the second mounting portion 25 is a mounting hole, and there are four second mounting portions 25. The second mounting portions 25 are connected to the tool body 1 by the second screw 4. Preferably, in order to ensure the stability of the connection between the second striking portion 22 and the tool body 1, the second striking portion 22 is circular or approximately circular, and the four second mounting portions 25 are evenly spaced apart along the circumference of the second striking portion 22. Of course, the number of second mounting portions 25 is not limited to four; it can also be two, three, or even more.

[0061] In one specific implementation, such as Figures 1 to 5 As shown, the main body shell 111 includes a front shell 1112, a middle shell 1113, and a rear cover 1114 arranged sequentially. The outer wall of the front shell 1112 has a first connecting portion 11121 protruding from it. The outer wall of the middle shell 1113 has a second connecting portion 11131 and a third connecting portion 11132 protruding from it. The outer wall of the rear cover 1114 has a fourth connecting portion 11141 protruding from it. An annular connecting structure 24 is sandwiched between the first connecting portion 11121 and the second connecting portion 11131. The first screw 3 passes through the first connecting portion 11121, the first mounting portion 23, and the second connecting portion 11131 in sequence, thereby connecting the front shell 1112, the first striking portion 21, and the second connecting portion 11131. This facilitates assembly and simplifies the assembly process. The outer periphery of the second striking part 22 is provided with a protruding structure 221, and the second mounting part 25 is provided on the protruding structure 221. The third connecting part 11132, the fourth connecting part 11141 and the protruding structure 221 abut against each other in a front-to-back direction. The second screw 4 passes through the second mounting part 25, the fourth connecting part 11141 and the third connecting part 11132 in sequence, thereby connecting the second striking part 22, the rear cover 1114 and the intermediate shell 1113. The assembly is convenient and the assembly process is simplified.

[0062] Second Implementation Method

[0063] The following is based on Figures 6 to 8 This invention provides a detailed description of the second embodiment of the power tool.

[0064] In this embodiment, such as Figures 6 to 8 As shown, the first mounting part 23 is a plug-in protrusion, and the housing 11 is provided with a plug-in groove (not shown in the figure). The plug-in protrusion and the plug-in groove are plugged in and the two are interference fit. Through the tight fit of the two structures, the first striking part 21 and the housing 11 are assembled. The structure is simple and the operation is convenient.

[0065] In one implementation, such as Figure 6 and Figure 7As shown, the housing 11 is provided with a thickened part 1111, which is provided in a one-to-one correspondence with the first mounting part 23. The insertion groove is provided on the thickened part 1111. By providing the thickened part 1111, the firmness of the assembly between the housing 11 and the first mounting part 23 is improved.

[0066] In one implementation, such as Figure 6 and Figure 7 As shown, when the insertion protrusion and the insertion slot are inserted into place, the second striking part 22 abuts against the rear surface wall of the housing 11, and the first striking part 21 abuts against the side surface wall of the housing 11. The striking structure 2 wraps around the outer wall of the housing 11 to prevent the striking structure 2 from shaking when striking the workpiece.

[0067] In one implementation, such as Figure 8 As shown, the first mounting part 23 is connected to the front end of the first striking part 21, as... Figure 6 and Figure 7 As shown, when assembling the striking structure 2 and the tool body 1, the striking structure 2 is installed on the tool body 1 from back to front, and the first mounting part 23 is inserted into the insertion slot from back to front.

[0068] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this utility model that may not be explicitly described.
