[0045] 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.

[0046] An electric reciprocating saw provided in an embodiment of the present application can simultaneously act on a first gripping portion 11a and a second gripping portion 12a provided on both sides of a saw blade 40, so that the force on the saw blade 40 is balanced during the cutting process, thereby improving the flatness of the cut surface of the material; in addition, when the saw blade 40 bends due to improper factors during the cutting process, the posture of the saw blade 40 can be corrected under the action of a stabilizing component 50, thereby improving the cutting stability.

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

[0048] Specifically, Figure 1 As shown, an electric reciprocating saw provided in an embodiment of the present application includes a housing 10 , a driving assembly 20 , a power supply assembly 30 , a saw blade 40 and a stabilization assembly 50 .

[0049] The housing 10 is provided with a first grip portion 11a and a second grip portion 12a. The structure of the electric reciprocating saw is similar to that of a traditional hand saw, i.e., a rectangular structure. During the cutting process of the electric reciprocating saw with this structure, the operator's hands can act on the first grip portion 11a and the second grip portion 12a at the same time, which is ergonomic and can balance the force of the saw blade 40 during the cutting process, thereby making it easier for the operator to grasp the cutting direction and improving the flatness of the cut surface of the material.

[0050] The driving assembly 20 is connected to the housing 10 , and the power supply assembly 30 is electrically connected to the driving assembly 20 . The power supply assembly 30 is used to provide power to the driving assembly 20 .

[0051] One end of the saw blade 40 is detachably connected to the drive assembly 20, and the saw blade 40 is located between the first grip portion 11a and the second grip portion 12a. The saw blade 40 is installed on or removed from the housing 10 by a first fastener. The specific structure of the first fastener is not limited in the embodiment of the present application. As an example, the first fastener is a combination of a screw and a nut.

[0052] The stabilizing assembly 50 is connected to one end of the saw blade 40 . When the saw blade 40 reciprocates under the driving force of the driving assembly 20 , the stabilizing assembly 50 tightens the saw blade 40 and is used to correct the posture of the saw blade 40 .

[0053] In the embodiment of the present application, when the saw blade 40 is making reciprocating motion, the saw blade 40 is locally bent due to force. The stabilizing component 50 can correct the posture of the saw blade 40 in the above situation so that the saw blade 40 can continue cutting, thereby ensuring the cutting stability of the electric reciprocating saw.

[0054] In an optional embodiment, the stabilizing assembly 50 is connected to an end of the saw blade 40 close to the driving assembly 20 .

[0055] Alternatively, the stabilizing assembly 50 is connected to an end of the saw blade 40 away from the driving assembly 20 .

[0056] As a replacement, both ends of the saw blade 40 are connected to stabilizing components 50, one stabilizing component 50 is connected to the end of the saw blade 40 close to the drive component 20, and the other stabilizing component 50 is connected to the end of the saw blade 40 away from the drive component 20.

[0057] In an optional embodiment, the drive assembly 20 includes a motor, a reduction mechanism, a crank and a connecting rod mechanism, the motor is connected to the reduction mechanism, the crank is connected to the motor, the crank is connected to the connecting rod mechanism, and the connecting rod mechanism is connected to the saw blade 40. When the motor is started, the motor output shaft starts to rotate, the speed level is adjusted by the reduction mechanism, and the saw blade 40 follows the connecting rod mechanism to reciprocate under the driving force of the motor. The reduction mechanism can be a planetary reduction or a multi-stage gear reduction. The reduction mechanism can also be other, which is not limited in the embodiment of the present application.

[0058] The power supply component 30 can be connected to the rear of the housing 10, or to the bottom of the housing 10. The power supply component 30 can be connected to any position of the housing according to specific needs, and the embodiment of the present application does not limit it. In addition, the power supply component 30 is a battery pack that can be recharged repeatedly, and / or is directly connected to a household power socket to power the drive component 20. The specific power supply method of the power supply component 30 used to power the drive component 20 is not specifically limited in the embodiment of the present application.

[0059] In an alternative embodiment, if Figure 1 and Figure 2 As shown, the electric reciprocating saw further includes a first mounting member 6a and a second mounting member 6b, wherein one end of the first mounting member 6a is detachably connected to one end of the saw blade 40, and the other end is connected to the driving assembly 20; one end of the second mounting member 6b is detachably connected to the other end of the saw blade 40, and the other end is connected to the stabilizing assembly 50. The first mounting member 6a and the second mounting member 6b can improve the convenience of mounting and dismounting the saw blade 40.

[0060] In an alternative embodiment, if Figure 1As shown, the stabilizing assembly 50 includes an elastic member 510, which is connected to the end of the second mounting member 6b away from the saw blade 40, and / or connected to the end of the first mounting member 6a away from the saw blade. When the saw blade 40 cuts the material and makes a reciprocating motion, the elastic member 510 is in a compressive deformation state or a tensile deformation state. When the saw blade 40 is locally deformed by force, the saw blade 40 can restore its original posture under the action of the elastic member 510, so that the saw blade 40 can continue to cut the material, ensuring the cutting stability of the electric reciprocating saw.

[0061] The elastic member 510 is preferably a spring. Of course, the elastic member 510 can also be other elastic deformable bodies, such as elastic rubber.

[0062] In an alternative embodiment, if Figure 1 and Figure 3 As shown, the stabilizing assembly 50 also includes a connecting plate 520, which is connected to the end of the second mounting member 6b away from the saw blade 40 and / or connected to an end of the first mounting member 6a away from the saw blade 40, and the elastic member 510 is connected to the connecting plate 520.

[0063] The spring is sleeved on the second mounting member 6b and / or the first mounting member 6a, one end of the spring is connected to the connecting plate 520, and the other end is connected to the housing 10. The size of the connecting plate 520 is larger than that of the second mounting member 6b and the first mounting member 6a. Connecting one end of the spring to the connecting plate 520 can improve the structural firmness and stability of the electric reciprocating saw.

[0064] Figure 1 FIG. 2 shows a schematic diagram of a state of the saw blade 40 in a reciprocating motion process under the driving force of the driving assembly 20. When the driving assembly 20 drives the saw blade 40 along Figure 1 When reciprocating in the direction of the middle arrow e, the second mounting member 6b, the elastic member 510 and the connecting plate 520 reciprocate along with the saw blade 40. During the reciprocating motion of the saw blade 40, the elastic member 510 is in a compressive deformation state or a tensile deformation state.

[0065] In an alternative embodiment, if Figure 2 and Figure 3 As shown, the housing 10 is provided with a first guide member 121, which is slidably connected or rollingly connected to the first mounting member 6a; the housing 10 is provided with a second guide member 111, which is slidably connected or rollingly connected to the second mounting member 6b.

[0066] A first guide member 121 matching the first mounting member 6 a is provided on the housing 10 . When the saw blade 40 reciprocates, the first mounting member 6 a follows the saw blade 40 and reciprocates under the guidance of the first guide member 121 .

[0067] It can be understood that the first guide member 121 and the second guide member 111 respectively form a first guide channel and a second guide channel, and the first mounting member 6a and the second mounting member 6b follow the saw blade 40 to reciprocate in the first guide channel and the second guide channel respectively. The first guide member 121 and the second guide member 111 can ensure the movement consistency of the saw blade 40, thereby improving the smoothness of the material cutting.

[0068] As an example, the first mounting member 6a reciprocates in the first guide channel, and the first mounting member 6a contacts the first guide member 111 for the above sliding connection. A linear bearing is connected between the first mounting member 6a and the first guide member 111 for the above rolling connection.

[0069] Figure 1 The first mounting member 6a and the second mounting member 6b are shown as circular structures. Figure 2 It is shown that the second mounting member 6b and the first mounting member 6a are both square structures. In addition, in the embodiment of the present application, it is also applicable that one of the first mounting member 6a and the second mounting member 6b is a circular structure and the other is a square structure.

[0070] Of course, the specific structures of the first mounting member 6a and the second mounting member 6b can also be other shapes, which are not specifically limited in the embodiment of the present application. As an example, the shapes of the first mounting member 6a and the second mounting member 6b are polygonal structures.

[0071] The circular structure of the first mounting member 6a and the second mounting member 6b can improve the smoothness of their movement, but the circular structure of the first mounting member 6a and the second mounting member 6b may rotate due to the force applied to the saw blade 40, thereby affecting the cutting effect.

[0072] In order to solve the above technical problems, the embodiment of the present application sets a limiting column 610 on the first mounting member 6a and / or the second mounting member 6b of the circular structure. The limiting column 610 can prevent the first mounting member 6a and / or the second mounting member 6b from rotating, thereby ensuring the cutting effect of the saw blade 40.

[0073] Specifically, Figure 2 and Figure 3 As shown, when the first mounting member 6a and / or the second mounting member 6b is a circular structure, the first mounting member 6a and / or the second mounting member 6b is provided with a limiting column 610. Correspondingly, the first guide member 121 and / or the second guide member 111 is provided with a through slot 1211, the through slot 1211 matches the limiting column 610, and the limiting column 610 is located in the through slot 1211, and the through slot 1211 is used to form a avoiding position for the limiting column 610 during the movement process.

[0074] In an alternative embodiment, if Figure 3 and Figure 4bAs shown, the second guide member 111 is provided with a first limiting protrusion 122 and a second limiting protrusion 123, which are located on both sides of the limiting column 610 and are opposite to the through slot 1211. The first limiting protrusion 122 and the second limiting protrusion 123 can limit the reciprocating motion distance of the saw blade 40, thereby preventing the elastic member 510 or the saw blade 40 from being damaged due to the large-scale motion of the saw blade 40, and ensuring the cutting stability of the electric reciprocating saw.

[0075] Figure 4a A schematic diagram of a first state of the saw blade 40 , the first mounting member 6 a , the second mounting member 6 b , the elastic member 510 and the connecting plate 520 is shown during the reciprocating motion of the saw blade 40 .

[0076] Figure 4b The diagram shows a second state of the saw blade 40 , the first mounting member 6 a , the second mounting member 6 b , the elastic member 510 and the connecting plate 520 when the saw blade 40 is in a reciprocating motion.

[0077] Figure 4b The second state shown is Figure 4a The first state shown in Figure 4a Schematic diagram of the state after movement in the direction of arrow s.

[0078] Figure 4a The first state in Figure 4b In the second state, the elastic members 510 are all in a deformed state, so as to be able to correct the bent and deformed posture of the saw blade 40 in time.

[0079] In an alternative embodiment, if Figure 3 As shown, the electric reciprocating saw further includes a mounting button 80, one end of which is connected to the end of the second mounting member 6b away from the saw blade 40, and the other end is a free end. A through hole is provided on the housing 10, the through hole is opposite to the mounting button 80, and the other end of the mounting button 80 can pass through the through hole.

[0080] The installation button 80 reciprocates along with the saw blade 40. Figure 4a When the installation button 80 moves in the direction of the arrow s, it can pass through the through hole and move to the outside of the housing 10. Figure 4a When moving in the opposite direction of the middle arrow s, the installation button 80 can be located inside the housing 10 or in the through hole.

[0081] During replacement of the saw blade 40, one end of the saw blade 40 is connected using a first fastener, and the installation button 80 is pressed from outside the housing 10 to enable telescopic movement of the second mounting member 6b, thereby further improving the connection between the other end of the saw blade 40 and the second mounting member 6b and improving the replacement efficiency of the saw blade 40.

[0082] In an alternative embodiment, if Figure 4a As shown, the shell 10 includes a first shell 110 and a second shell 120, the first shell 110 is connected to the second shell 120, the first gripping portion 11a and the second gripping portion 12a are respectively arranged on the first shell 110 and the second shell 120, the saw blade 40 is installed on the first shell 110 and the second shell 120, the first shell 110 and the second shell 120 are connected by an adjusting member 90, the adjusting member 90 is connected between the first shell 110 and the second shell 120, and the adjusting member 90 is used to adjust the distance between the first shell 110 and the second shell 120, so that the electric reciprocating saw in the embodiment of the present application can be suitable for saw blades 40 of different sizes.

[0083] Specifically, the adjusting member 90 includes a connecting rod 910 and a second fastener 920 , adjusts the length of the connecting rod 910 between the first shell 110 and the second shell 120 , and fixes them with a plurality of second fasteners 920 .

[0084] In an alternative embodiment, if Figure 1 As shown, the housing 10 is further provided with a third grip portion 12b, which is arranged adjacent to the second grip portion 12a. The second grip portion 12a and the third grip portion 12b are arranged on the housing 10 to adapt to the operating habits of operators with different needs.

[0085] In an alternative embodiment, if Figure 1 As shown, the electric reciprocating saw further includes a switch 70, which is connected to the housing 10 and electrically connected to the drive assembly 20, and is used to turn on or off the drive assembly 20. The specific structure of the switch 70 is not specifically limited in the embodiment of the present application, and the switch 70 includes a push type, a rotation type, or a left-right toggle type.
