[0023] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the electric hammer provided in the embodiment of the present application includes an electric hammer body 100 and a handle 200. The first end 210 of the handle 200 is flexibly connected to the electric hammer body 100, and the first end 210 of the handle 200 has a maximum movable connection position and a minimum movable connection position relative to the electric hammer body 100. A shock absorbing module 230 is provided between the first end 210 of the handle 200 and the electric hammer body 100, and the second end 220 of the handle 200 is movably connected to the electric hammer body 100. The shock absorbing module 230 is used to reduce the shock of the electric hammer when using the electric hammer, thereby increasing the comfort of the user.

[0026] In this embodiment, the first end 210 of the handle 200 is provided with a mode switching mechanism 240. When the mode switching mechanism 240 is in the first position, the electric hammer is in the shock absorbing mode. When the mode switching mechanism 240 is in the second position, the mode switching mechanism 240 abuts against the electric hammer body 100, and the mode switching mechanism 240 limits the position of the first end 210 of the handle 200 to the maximum movable connection position, and the electric hammer is in the non-shock absorbing mode. In other words, the electric hammer provided in the embodiment of the present application has a shock absorbing mode and a non-shock absorbing mode. When the user prefers to use the shock absorbing mode, the electric hammer can be adjusted to the shock absorbing mode. If the user prefers to use the non-shock absorbing mode, the electric hammer can be adjusted to the non-shock absorbing mode. It is flexible to use and meets the different needs of users in different situations.

[0027] In other words, in the embodiment of the present application, the mode switching mechanism 240 can switch the use mode of the electric hammer. When the mode switching mechanism 240 is in the first position, the electric hammer is in the shock absorption mode. In this mode, the shock absorption module 230 plays a role, and the electric hammer has a shock absorption effect, which can increase the comfort of the user when using the electric hammer. When the mode switching mechanism 240 is in the second position, the electric hammer is in the non-shock absorption mode. At this time, the mode switching mechanism 240 is against the electric hammer body 100, and the mode switching mechanism 240 limits the position of the first end 210 of the handle 200 to the maximum active connection position. That is to say, when the electric hammer is in the non-shock absorption mode, the mode switching mechanism 240 is in the non-shock absorption mode. The switching mechanism 240 abuts against the electric hammer body 100, so that the first end 210 of the handle 200 cannot move in the direction close to the electric hammer body 100, and the mode switching mechanism 240 limits the position of the first end 210 of the handle 200 to the maximum movable connection position. The position of the first end 210 of the handle 200 is located in the maximum movable connection position, and the first end 210 of the handle 200 cannot move in the direction away from the electric hammer body 100, thereby making the position of the first end 210 of the handle 200 relatively fixed, and the shock absorbing module 230 cannot function, so that the electric hammer is in the non-shock absorbing mode, and the working efficiency of the electric hammer is relatively high at this time.

[0028] The electric hammer provided in the embodiment of the present application can freely switch modes. The user can choose the shock-absorbing mode or the non-shock-absorbing mode according to his own situation, usage scenario, etc., which is more flexible to use and suitable for the diverse needs of users.

[0029] It is worth noting that, in the embodiment of the present application, the maximum movable connection position of the first end 210 of the handle 200 relative to the electric hammer body 100 refers to the position of the first end 210 of the handle 200 relative to the electric hammer body 100, which is farthest from the electric hammer body 100, and the minimum movable connection position of the first end 210 of the handle 200 relative to the electric hammer body 100 refers to the position of the first end 210 of the handle 200 relative to the electric hammer body 100, which is closest to the electric hammer body 100, that is, the position closest to the electric hammer body 100. In other words, the first end 210 of the handle 200 can move between the maximum movable connection position and the minimum movable connection position relative to the electric hammer body 100, the first end 210 of the handle 200 moves in the direction close to the electric hammer body 100, and the mobile terminal is the minimum movable connection position, and the first end 210 of the handle 200 moves in the direction away from the electric hammer body 100, and the mobile terminal is the maximum movable connection position.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the first end 210 of the handle 200 is provided with a mounting cavity 211, the mounting cavity 211 has an opening facing the electric hammer body 100, and a first movable connecting member 213 is provided in the mounting cavity 211. A second movable connecting member 111 is provided at the movable connection between the electric hammer body 100 and the first end 210 of the handle 200, the second movable connecting member 111 extends from the opening into the mounting cavity 211, and the second movable connecting member 111 is provided with an elongated hole 112. The first movable connecting member 213 passes through the elongated hole 112, and the first movable connecting member 213 can move back and forth in the length direction of the elongated hole 112. That is, the first end 210 of the handle 200 is flexibly connected to the electric hammer body 100 through the matching connection of the first movable connecting piece 213 and the second movable connecting piece 111. When the first movable connecting piece 213 is located at one end of the long hole 112 close to the electric hammer body 100, the first end 210 of the handle 200 is located at the minimum movable connection position. When the first movable connecting piece 213 is located at one end of the long hole 112 away from the electric hammer body 100, the first end 210 of the handle 200 is located at the maximum movable connection position. This arrangement has a simple structure, is easy to assemble, and has low cost.

[0031] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, a detachable fastening member 110 is provided at the movable connection between the electric hammer body 100 and the first end 210 of the handle 200, and a second fastening member 111 is provided on the fastening member 110. The provision of the fastening member 110 facilitates the production, processing and assembly of the electric hammer.

[0032] In some embodiments of the present application, the second end 220 of the handle 200 is rotatably connected to the electric hammer body 100. The rotatable connection method not only meets the requirements of the electric hammer's shock absorption performance, but also facilitates the assembly and processing of the electric hammer.

[0033] Exemplarily, the long strip hole 112 is an arc-shaped long strip hole 112, and the extension direction of the arc-shaped long strip hole 112 is a circumferential direction with the second end 220 of the handle 200 and the rotary connection of the electric hammer body 100 as the center. Since the second end 220 of the handle 200 is rotatably connected to the electric hammer body 100, when the electric hammer vibrates, the movement of the first end 210 of the handle 200 is centered on the rotary connection of the second end 220 of the handle 200 and the electric hammer body 100. Circular motion, thus, the elongated hole 112 is configured to be an arc-shaped elongated hole 112 with the rotational connection between the second end 220 of the handle 200 and the electric hammer body 100 as the center of the circle, so that when the first movable connecting member 213 moves in the arc-shaped elongated hole 112, it can move along the extension direction of the arc-shaped elongated hole 112, reducing the first movable connecting member 213 touching the wall of the arc-shaped elongated hole 112 when moving, so that the first movable member moves more smoothly in the arc-shaped elongated hole 112.

[0034] In order to reduce the twisting of the first end 210 of the handle 200 in the width direction of the electric hammer, two limiting plates 212 are provided in the installation cavity 211. The two limiting plates 212 are spaced and arranged opposite to each other in the first direction. The first direction is the axial direction of the rotation of the second end 220 of the handle 200, that is, the width direction of the electric hammer. A limiting protrusion 113 is also provided on the fastener 110. The limiting protrusion 113 extends into the installation cavity 211 and extends between the two limiting plates 212. The limiting protrusion 113 cooperates with the two limiting plates 212 to limit the position of the handle 200 in the first direction. In other words, the limiting protrusion 113 cooperates with the two limiting plates 212 to reduce the twisting of the first end 210 of the handle 200 in the width direction of the electric hammer, thereby avoiding the twisting of the first end 210 of the handle 200 in the width direction of the electric hammer affecting the strength of the second end 220 of the handle 200.

[0035] In some embodiments of the present application, Figure 2 As shown, the fastening member 110 is provided with a shielding edge 114, which extends from the opening into the installation cavity 211 and is located at the opening of the installation cavity 211. The shielding edge 114 is located at the opening of the installation cavity 211 and is used to shield the structure in the installation cavity 211.

[0036] In some embodiments of the present application, the shock absorbing module 230 includes at least one elastic member, which is installed in the installation cavity 211 and between the fastening member 110 and the cavity wall of the installation cavity 211. Exemplarily, the elastic member is a spring.

[0037] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the first movable connecting member 213 is a connecting rod, both ends of the connecting rod pass through and extend out of the mounting cavity 211, and the connecting member can rotate relative to the side wall of the mounting cavity 211, and the cross section of the connecting rod is a special shape. The mode switching structure includes a stopper 241, which is arranged in the mounting cavity 211, and the stopper 241 is sleeved and installed on the connecting rod. The stopper 241 changes position by rotating the connecting rod. When the stopper 241 is rotated to the second position, one end of the stopper 241 abuts against the electric hammer body 100. That is to say, by rotating the connecting rod, the stop block 241 can rotate accordingly. When the electric hammer needs to change the mode, the connecting rod is rotated, thereby driving the stop block 241 to rotate. When the connecting rod is rotated until the stop block 241 abuts against the electric hammer body 100, the stop block 241 simultaneously pushes the first end 210 of the handle 200 to move in a direction away from the electric hammer body 100, so that the connecting rod moves with the first end 210 of the handle 200 to the end of the long hole 112 away from the electric hammer body 100 (i.e., the maximum movable connection position), at this time, the electric hammer is in a non-shock absorption mode. That is to say, in the embodiment of the present application, the connecting rod not only plays the role of movably connecting the first end 210 of the handle 200 and the electric hammer body 100, but also plays the role of adjusting the position of the mode switching mechanism 240, and cooperates with the mode switching mechanism 240 to limit the position of the first end 210 of the handle 200, so that the electric hammer is in a non-shock absorption mode. The connecting rod and the mode switching mechanism 240 have a simple structure, ingenious cooperation, simple assembly, and low cost.

[0038] In this embodiment, the cross section of the connecting rod is a special shape, where the special shape refers to a non-circular shape, for example, the cross section of the connecting rod is an oblong, square, hexagonal, quadrilateral, etc. The setting of the cross section of the connecting rod being a special shape enables the connecting rod and the stop block 241 to be sleeved, that is, during installation, one end of the connecting rod can be inserted into the installation cavity 211 from one side of the first end 210 of the handle 200, pass through the stop block 241, pass through the long hole 112, pass through the second stop block 241, and then pass out of the installation cavity 211 from the other side of the first end 210 of the handle 200. This setting facilitates the processing and assembly of the electric hammer.

[0039] In order to facilitate the rotation of the connecting rod, the mode switching structure also includes a mode switching switch 242. The mode switching switch 242 is arranged on the outside of the installation cavity 211, and the mode switching switch 242 is installed on the connecting rod extending out of the installation cavity 211. The mode switching switch 242 controls the rotation of the connecting rod and controls the position change of the blocking block 241.

[0040] Exemplarily, the number of the blocking blocks 241 is set to two, and the two blocking blocks 241 are respectively located on both sides of the installation cavity 211 in the width direction of the electric hammer. For example, the two limiting plates 212 respectively form two installation spaces with the side walls of the installation cavity 211, that is, one installation space is formed between one limiting plate 212 and the side wall of the installation cavity 211 opposite thereto, and another installation space is formed between the other limiting plate 212 and the side wall of the installation cavity 211 opposite thereto, and the two blocking blocks 241 are respectively installed in the two installation spaces. Of course, the number of the blocking block 241 can also be one, which is not specifically limited here.

[0041] Exemplarily, there are two mode switching switches 242, which are respectively mounted at two ends of the connecting rod. Of course, there may also be one mode switching switch 242, which is not specifically limited here.

[0042] Exemplarily, in some embodiments of the present application, the mode switching structure also includes a locking structure. When the mode switching switch 242 is turned to the shock absorption mode switch position or the non-shock absorption mode switch position, the locking structure locks the position of the mode switching switch 242, thereby locking the position of the stop block 241, so that the electric hammer can be stably in the shock absorption mode or the non-shock absorption mode. This setting can avoid the position change of the stop block 241 or the mode switching switch 242 that may be caused during the vibration of the electric hammer.

[0043] For example, Figure 5 As shown, the mode switching switch 242 is a knob, and at least two fixing grooves 243 are arranged on the side of the knob facing the handle 200, wherein two adjacent fixing grooves 243 in the circumferential direction are respectively a damping mode fixing groove and a non-dampering mode fixing groove. A mounting groove 244 is arranged at the position corresponding to the knob at the first end 210 of the handle 200, and a locking elastic member (not shown in the figure) and a locking bead (not shown in the figure) are arranged in the mounting groove 244, wherein the damping mode fixing groove and the non-dampering mode fixing groove arranged on the knob, and the mounting groove 244, the locking elastic member and the locking bead arranged on the first end 210 of the handle 200 form a locking structure, when the mode switching switch 242 is turned to the damping mode switch position, the locking bead is turned into the damping mode fixing groove under the action of the locking elastic member, and when the mode switching switch 242 is turned to the non-dampering mode switch position, the locking bead is turned into the non-dampering mode fixing groove under the action of the locking elastic member.
