[0044] In order to thoroughly understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other implementation methods.

[0045] The electric tool provided in the embodiment of the present application takes an electric wrench as an example. Of course, the electric tool in the embodiment of the present application can also be an electric hammer, an electric drill, an impact drill, etc. The impact force received by the electric tool during operation and the vibration generated by the driving member itself are transmitted to the handle through the driving housing, affecting the operation effect of the operator. In order to reduce the vibration occurring on the handle, an elastic member is connected between the driving housing and the handle to reduce the impact of the vibration, but due to the structure of the electric tool itself and the connection position of the elastic member, the shock absorbing effect is general. Electric tools generally include pistol type, straight handle type, corner type, etc. Due to the different structures of the electric tools, the transmission direction of the vibration force generated by the electric tools during operation is different, which directly affects whether the elastic member can effectively absorb and disperse the vibration force.

[0046] In response to the above technical problems, an embodiment of the present application provides an electric tool, which has a straight-handle structure, that is, the handle is located in the extension direction of the motor axis, and the first shell is provided with a plurality of mounting portions extending in a direction perpendicular to the motor axis, and at least two mounting portions are located on both sides of the motor axis, and elastic parts are installed in the mounting portions so that the elastic parts can evenly share the vibration generated during the operation of the electric tool from multiple directions, reduce the impact of the vibration, and increase the service life of the electric tool.

[0047] The electric tool provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0048] Specifically, Figure 1 and Figure 2 As shown, an embodiment of the present application provides an electric tool, which includes a first housing 10 , a grip assembly 20 , a first fastener 30 and an elastic member 40 .

[0049] The first housing 10 is used to accommodate a motor (not shown in the figure), and one end of the first housing 10 is provided with a plurality of mounting portions 110 extending in a direction perpendicular to the motor axis, and at least two mounting portions 110 are provided on both sides of the motor axis. At least two mounting portions 110 are located on both sides of the plane where the motor axis is located.

[0050] The grip assembly 20 extends along the axis direction of the first housing 10, that is, the electric tool has a straight handle structure. Figure 1The overall structure diagram of the straight handle electric wrench is shown in FIG. One end of the grip assembly 20 is connected to the mounting portion 110, and the other end is a free end, which is used for the operator to hold. The grip assembly 20 includes two handle covers 200 that cover and connect to the mounting portion 110, and the two handle covers 200 have abutment portions 201 connected to the mounting portion 110.

[0051] The elastic member 40 is located between the abutting portion 201 and the mounting portion 110 . The first fastener 30 penetrates through the abutting portion 201 , the mounting portion 110 and the elastic member 40 , and locks the elastic member 40 between the abutting portion and the mounting portion 110 .

[0052] The vibration generated during the operation of the power tool is transmitted to the grip assembly 20 through the first housing 10 to the elastic member 40. Generally, the impact force generated during the operation of the power tool acts on the wall to form a reaction force, which will generate vibration and the motor will generate vibration.

[0053] The vibration generated during the operation of the electric tool can be absorbed and dispersed by the elastic members located on both sides of the motor axis, thereby further reducing the vibration and the impact of the vibration.

[0054] The material of the elastic member 40 includes but is not limited to rubber and polymer. The elastic member 40 can effectively absorb and disperse the vibration force, thereby reducing the vibration force transmitted to the handle.

[0055] In an alternative embodiment, if Figure 2 and Figure 3 As shown, the grip assembly 20 includes a second shell 210 and a third shell 220 . The second shell 210 matches the third shell 220 . The second shell 210 and the third shell 220 respectively form two handle covers 200 .

[0056] The second housing 210 and the third housing 220 are connected by snap-fitting and mating, and the second housing 210 and the third housing 220 contact the first housing 10 to improve the integrity of the electric tool.

[0057] The elastic member 40 includes a first elastic member 41 and a second elastic member 42 . The first elastic member 41 is connected between the second housing 210 and the mounting portion 110 , and the second elastic member 42 is connected between the third housing 220 and the mounting portion 110 .

[0058] In an alternative embodiment, if Figure 2 , Figure 3 , Figure 4a and Figure 4bAs shown, the first housing 10 is provided with a first mounting column 111, the second housing 210 is provided with a second mounting column 211, and the third housing 220 is provided with a third mounting column 221, and the first fastener 30 is inserted into the first mounting column 111, the second mounting column 211, the third mounting column 221 and the abutment portion 201, so that the second housing 210 and the third housing 220 are connected to the first housing 10. The first mounting column 111 communicates with two oppositely arranged mounting portions 110, and the two mounting portions 110 are located on both sides of the motor axis.

[0059] Preferably, the first fastener 30 includes a bolt 310 and a nut 320, the bolt 310 is inserted into the first mounting column 111, the second mounting column 211, the third mounting column 221 and the abutment portion 201, the abutment portion 201 includes a mounting hole, and both ends of the bolt 310 respectively pass through the mounting holes on the second shell 210 and the third shell 220, and are locked by the nut 320, so that the bolt 310 and the nut 320 abut against the handle cover 200, thereby connecting the second shell 210 and the third shell 220 to the first shell 10.

[0060] In an alternative embodiment, if Figure 4a and Figure 4b As shown, the second mounting column 211 is connected to the third mounting column 221 . Figure 4b Shows Figure 4a Schematic diagram of the cross section at AA in the middle. Figure 4a The center AA is the connection point of the mounting portion 110 , the first fastening member 30 , the first elastic member 41 and the second elastic member 42 .

[0061] It can be understood that the second mounting column 211 and / or the third mounting column 221 are relatively long. Figure 5 As shown, Figure 5 2 shows a third mounting column 221 of a longer structure. When the second mounting column 211 is connected to the third mounting column 221, the first elastic member 41 and the second elastic member 42 are respectively sleeved on the second mounting column 211 and the third mounting column 221, and the bolt 310 is located in the second mounting column 211 and the third mounting column 221, which can effectively reduce the vibration between the bolt 310 and the second housing 210, the third housing 220 and the nut 320.

[0062] In an alternative embodiment, if Figure 4b As shown, the first elastic member 41 is a first shock absorbing ring 411 , which is sleeved on the second mounting column 211 , and the first shock absorbing ring 411 abuts between the mounting portion 110 , the second mounting column 211 and the second shell 210 .

[0063] The second elastic member 42 is a second shock absorbing ring 421 . The second shock absorbing ring 421 is sleeved on the third mounting column 221 . The second shock absorbing ring 421 abuts against between the mounting portion 110 , the third mounting column 221 and the third housing 220 .

[0064] The vibration generated during the operation of the power tool passes through the first housing 10 to the first plurality of shock absorbing rings 411 and the second plurality of shock absorbing rings 421, and then to the second housing 210 and the third housing 220, and then to the bolt 310 from the second housing 210 and the third housing 220, that is, the second mounting column 211 and the third mounting column 221. The influence of the vibration on the first fastener 30 is effectively reduced, thereby ensuring the connection stability of the second housing 210, the third housing 220 and the first housing 10.

[0065] In another alternative embodiment, if Figure 3 and Figure 4c As shown, the second mounting column 211 and the third mounting column 221 are spaced apart from each other.

[0066] Figure 3 2 shows that a third mounting column 221 with a shorter length is provided on the third housing 220. In this way, the second mounting column 211 and the third mounting column 221 are not in contact, and the vibration generated during the operation of the power tool is transmitted to the first elastic member 41 and the second elastic member 42 through the first housing 10, and then transmitted to the second housing 210 and the third housing 220 by the first elastic member 41 and the second elastic member 42 respectively. The transmission of vibration by the first elastic member 41 and the second elastic member 42 can improve the shock absorption effect. In addition, based on the shortened length of the second mounting column 211 and the third mounting column 221, that is, the occupied space of the second mounting column 211 and the third mounting column 221 is reduced, so that the first elastic member 41 and the second elastic member 42 can be used to fill the reduced space, that is, the volume of the first elastic member 41 and the second elastic member 42 is increased. The larger the volume of the first elastic member 41 and the second elastic member 42, the better the effect of absorbing and dispersing the vibration force, and the shock absorption effect is further improved.

[0067] In an alternative embodiment, if Figure 4c As shown, the first elastic member 41 is a third damping ring 412 , which is sleeved between the first fastener 30 and the second mounting column 211 , and abuts between the mounting portion 110 , the first fastener 30 , the second mounting column 211 and the second shell 210 .

[0068] The second elastic member 42 is a fourth damping ring 422 , which is sleeved between the first fastener 30 and the third mounting column 221 . The fourth damping ring 422 abuts against the mounting portion 110 , the first fastener 30 , the third mounting column 221 and the third housing 220 .

[0069] The third damping ring 412 is sleeved on the bolt 310 and the second mounting column 211, and the fourth damping ring 422 is sleeved on the bolt 310 and the third mounting column 221. The vibration generated during the operation of the power tool is transmitted to the third damping ring 412 and the fourth damping ring 422 through the first housing 10, and then transmitted to the second mounting column 211, the third mounting column 221 and the bolt 310 by the third damping ring 412 and the fourth damping ring 422. The third damping ring 412 and the fourth damping ring 422 contact the bolt 310, and also contact the second mounting column 211 and the third mounting column 221, so that the vibration force can be transmitted more dispersedly, reducing the vibration transmitted to the handle.

[0070] In an alternative embodiment, if Figure 4c and Figure 6 As shown, the third shock absorbing ring 412 has the same structure as the fourth shock absorbing ring 422, wherein the fourth shock absorbing ring 422 is provided with a first ring 4a and a second ring 4b, the first ring 4a is connected to the second ring 4b, the inner diameter of the first ring 4a matches the outer diameter of the first fastener 30, and the inner diameter of the second ring 4b matches the outer diameter of the third mounting column 221.

[0071] In the embodiment of the present application, the inner wall of the third damping ring 412 abuts against the bolt 310 and the outer wall of the second mounting column 211 at the same time, and the outer wall of the third damping ring 412 abuts against the first shell 10 and the second shell 210. The inner wall of the fourth damping ring 422 abuts against the bolt 310 and the outer wall of the third mounting column 221 at the same time, and the outer wall of the third damping ring 412 abuts against the first shell 10 and the third shell 220. The fourth damping ring 422 is provided with two first circles 4a and second circles 4b of different sizes, so that the vibration on the fourth damping ring 422 can be transmitted to the third mounting column 221 and the bolt respectively, thereby improving the damping effect and also improving the connection effect between the fourth damping ring 422 and the third shell 220. The third damping ring 412 and the fourth damping ring 422 have the same structure and are symmetrically arranged, which will not be repeated here.

[0072] In an alternative embodiment, if Figure 7 and Figure 4c As shown, the third housing 220 is further provided with a first accommodating groove 2211 for accommodating the fourth damping ring 422 , the outer diameter of the second ring matches the first accommodating groove 2211 , and the first accommodating groove 2211 and the third mounting column 221 form abutment portion 201 .

[0073] Accommodating the fourth damping ring 422 in the first accommodating groove 2211 can ensure the connection effect between the fourth damping ring 422 and the third housing 220, while improving the damping effect of the fourth damping ring 422. Similarly, the second housing 210 is also provided with an accommodating groove for accommodating the third damping ring 412, and the accommodating groove for accommodating the third damping ring 412 and the second mounting column 211 also form abutting portion 201.

[0074] In an optional embodiment, the first housing 10 is provided with a second accommodating groove 112, the second accommodating groove 112 forms the mounting portion 110, the second accommodating groove 112 is used to accommodate the first ring 4a, and the outer diameter of the first ring 4a matches the second accommodating groove 112. The midpoint of the distance between the two oppositely arranged second accommodating grooves 112 is located on the extension line of the motor axis, and the elastic member 40 installed in the oppositely arranged second accommodating grooves 112 can evenly share the vibration generated during the operation of the electric tool.

[0075] The two oppositely arranged second accommodating grooves 112 are used to accommodate the third shock absorbing ring 412 and the fourth shock absorbing ring 422 respectively. One end of the elastic third shock absorbing ring 412 and the fourth shock absorbing ring 422 are installed in the mounting part 110, i.e., the second accommodating groove 112, which can effectively absorb and disperse the vibration force transmitted from the first shell 10, and at the same time, it can also ensure the connection effect between the third shock absorbing ring 412 and the fourth shock absorbing ring 422 and the mounting part 110, thereby further ensuring the shock absorption effect.

[0076] It should be understood that the above embodiments are exemplary and are not intended to include all possible implementations included in the claims. Various modifications and changes may be made on the basis of the above embodiments without departing from the scope of the present disclosure.
