Description

Technical Field

[0001] The invention relates to the technical field of safety control, and in particular to an electric tool. Background Art

[0002] As people's awareness and requirements for vegetation ecology and urban gardens increase, power tools are used more and more widely in garden maintenance. They have the advantages of high efficiency and ease of use.

[0003] However, in actual use, sometimes due to the operator's negligence, the power tool may be started by mistake, causing the power tool to work suddenly, which may easily injure the human body.

[0004] Therefore, existing power tools are generally designed with a double-action switch mechanism to control the opening and closing of the power tool. That is, two switches are installed in series, and two buttons are set, each button corresponding to one switch. Only when the two buttons are pressed at the same time, so that the two switches are turned on at the same time, can the power tool be started, thereby improving the safety of the power tool. However, the double-action switch mechanism requires two switches, and has more wiring and a complex structure, resulting in the need to occupy a larger internal space of the power tool. Summary of the invention

[0005] Based on this, it is necessary to provide an electric tool that saves internal space to address the problem that the double-action switch mechanism of the electric tool in the prior art requires two switches, has more wiring and a complex structure, resulting in a larger internal space of the electric tool.

[0006] An electric tool comprises a housing, a micro switch, a first actuating member, a trigger member, a linkage member and a second actuating member;

[0007] The micro switch is arranged in the housing;

[0008] The trigger member is rotatably connected to the first action member; the first action member is rotatably connected to the housing and is configured to operably drive the trigger member to move closer to or away from the micro switch;

[0009] The linkage member is movably suspended in the housing, and one end of the linkage member is connected to the second action member, and the other end of the linkage member is connected to the trigger member;

[0010] The second action member is movably disposed on the housing, and is configured to operably drive the linkage member to move, thereby driving the trigger member to rotate, and then triggering the micro switch when the trigger member approaches the micro switch and the trigger member rotates.

[0011] In the above-mentioned electric tool, the rotation of the first action member drives the trigger member to move closer to the micro switch; and the second action member drives the trigger member to rotate. Driven by the first action member and the second action member, the trigger member presses the micro switch to trigger the micro switch, thereby achieving the purpose of controlling the micro switch to be turned on and off. In addition, the electric tool only needs one micro switch to achieve dual-action control, which reduces wiring, simplifies the structure, and saves the internal space of the electric tool.

[0012] In one embodiment, the power tool further comprises a rotating block rotatably connected to the housing;

[0013] The end of the linkage member away from the trigger member is connected to the rotating block, and the second action member is in conflict with the rotating block, so that during the movement of the second action member, the rotating block can be driven to rotate, thereby driving the linkage member to move. In this way, the second action member drives the rotating block to rotate, thereby driving the linkage member to move, and the structure is simple, and the consistency of the movements of each component is good.

[0014] In one embodiment, the second action member has an interfering portion interfering with the rotating block.

[0015] In one embodiment, the rotating block includes an operating end and a pulling end relative to the operating end, the connection point between the rotating block and the shell is located between the operating end and the pulling end, the operating end conflicts with the conflicting portion, and the pulling end is connected to the linkage member.

[0016] In one embodiment, the linkage member is a pull cord. In this way, since the installation of the pull cord occupies a small space, the internal space of the power tool is further saved. In addition, since the pull cord has a low cost, it is helpful to reduce the cost of the power tool.

[0017] In one embodiment, the electric tool further comprises a sleeve fixedly mounted in the housing, and the pull cord is movably inserted into the sleeve along the sleeve. In this way, the movement path of the pull cord is limited by the sleeve, so that the movement path of the pull cord driven by the second action member each time remains unchanged, with good consistency, stable operation, and safety and reliability.

[0018] In one embodiment, the trigger member includes a mounting end and a connecting end relative to the mounting end, the mounting end is rotatably connected to the first action member, and the connecting end is connected to the linkage member.

[0019] In one embodiment, the trigger member further includes a trigger portion protruding from the mounting end, and the trigger portion is used to trigger the micro switch.

[0020] In one embodiment, the trigger part has a contact surface for contacting the micro switch, and the contact surface is inclined relative to the micro switch, so that when the trigger part moves towards the micro switch under the drive of the first action member, the contact surface contacts the micro switch, thereby prompting the trigger part to rotate in the inclined direction of the inclined surface. In this way, when the trigger part moves close to the micro switch under the drive of the first action member, the contact surface contacts the micro switch, and as the trigger part continues to move close to the micro switch, since the second action member does not move, the linkage member does not drive the trigger part to rotate, and the micro switch slides relatively to the trigger part in the contact surface, thereby prompting the trigger part to rotate in the inclined direction of the inclined surface, preventing the trigger part from triggering the micro switch only when it approaches the micro switch under the drive of the first action member.

[0021] In one embodiment, the electric tool further comprises a first rotating shaft mounted on the first action member, and the trigger member is rotatably mounted on the first rotating shaft, thereby achieving a rotatable connection of the trigger member.

[0022] In one embodiment, the electric tool further comprises a first torsion spring mounted on the first rotating shaft;

[0023] The first torsion spring includes a first torque arm and a second torque arm, wherein the first torque arm is connected to the first action member, and the second torque arm is connected to the trigger member, so as to provide a blocking force for blocking the trigger member from rotating around the first rotation axis in the direction in which the trigger portion approaches the micro switch. In this way, when only the first action member rotates and the second action member does not move, the trigger member follows the first action member to move toward the micro switch, but the trigger portion rotates away from the micro switch under the action of the first torsion spring, thereby ensuring that in this case, the force between the trigger portion and the micro switch is small and the micro switch will not be triggered.

[0035] Figure 1 It is a structural schematic diagram of an electric tool in an embodiment of the present invention in a shutdown state. Figure 2 for Figure 1 For ease of description, only the structures related to the embodiment of the present invention are shown.

[0036] like Figure 1 and Figure 2 As shown, the electric tool in one embodiment of the present invention includes a housing 10, a first action member 20, a trigger member 30, and a second action member 40 (see Figure 2 ), micro switch 50 and linkage part 60.

[0037] The micro switch 50 is disposed in the housing 10. The trigger member 30 is rotatably connected to the first action member 20. The first action member 20 is rotatably connected to the housing 10, and is configured to operably drive the trigger member 30 to move closer to or away from the micro switch 50. The linkage member 60 is movably suspended in the housing 10, and one end is connected to the second action member 40, and the other end is connected to the trigger member 30. The second action member 40 is movably disposed in the housing 10, and is configured to operably drive the linkage member 60 to move, thereby driving the trigger member 30 to rotate, and then triggering the micro switch 50 when the trigger member 30 approaches the micro switch 50 and the trigger member 30 rotates.

[0038] In the above-mentioned electric tool, the trigger member 30 is driven to move close to the micro switch 50 by the rotation of the first action member 20; and the trigger member 30 is driven to rotate by the second action member 40. The trigger member 30 is driven by the first action member 20 and the second action member 40 to press the micro switch 50 so that the micro switch 50 is triggered, thereby achieving the purpose of controlling the conduction and disconnection of the micro switch 50. In addition, the above-mentioned electric tool only needs one micro switch 50 to realize double-action control, which reduces wiring and simplifies the structure, thereby saving the internal space of the electric tool. In addition, the trigger member 30 is driven by the first action member 20 and the second action member 40 to move and rotate close to the micro switch 50, thereby triggering the micro switch 50. The consistency of each action of each component makes the operation stability of the electric tool good. In other words, generally, the micro switch is not triggered when only the first action member 20 or the second action member 40 is in action; and the micro switch is not triggered when both the first action member 20 and the second action member 40 are in action.

[0039] In the embodiment of the present invention, the electric tool further comprises a driving member 70 disposed in the housing 10, and the driving member 70 is electrically connected to the micro switch 50, so that the micro switch 50 controls the start or stop of the driving member 70. That is, when the first action member 20 drives the trigger member 30 to move close to the micro switch 50, and the second action member 40 drives the trigger member 30 to rotate, the trigger member 30 triggers the switch to turn on, so that the driving member 70 is turned on and power is output. Optionally, the driving member 70 can be a motor.

[0040] In some embodiments, the electric tool further includes a transmission assembly (not shown) and a work execution assembly 80, wherein the transmission assembly is disposed in the housing 10, and the work execution assembly 80 is mounted on the housing 10. The transmission assembly is connected between the driving member 70 and the work execution assembly 80 to transmit the power output by the driving member 70 to the work execution assembly 80, so that the work execution assembly 80 performs a corresponding action, such as cutting branches, mowing grass, etc.

[0041] In some embodiments of the present invention, the trigger member 30 includes a mounting end and a connecting end 32 opposite to the mounting end, the mounting end is rotatably connected to the first action member 20 , and the connecting end 32 is connected to the linkage member 60 .

[0042] In some embodiments, the trigger member 30 further includes a trigger portion 340 protruding from the mounting end, and the trigger portion 340 is used to trigger the micro switch 50. In this way, the trigger member 30 moves toward the direction close to the micro switch 50 under the drive of the first action member 20, and the trigger portion 340 moves toward the direction close to the micro switch 50 along with the trigger member 30, and the trigger member 30 rotates toward the direction close to the micro switch 50 under the drive of the second action member 40, so that the trigger portion 340 presses and triggers the micro switch 50. Specifically, the trigger portion 340 is a protrusion.

[0043] Specifically in the embodiment, the trigger part 340 has a contact surface 342 for interfering with the micro switch 50, and the contact surface 342 is inclined relative to the micro switch 50, so that when the trigger part 30 moves close to the micro switch 50 driven by the first action part 20, the contact surface 342 contacts the micro switch 50, and as the trigger part 30 continues to move close to the micro switch 50, since the second action part 40 does not move, the linkage part 60 does not drive the trigger part 30 to rotate, and the micro switch 50 slides relatively to the trigger part 340 in the contact surface 342, thereby prompting the trigger part 30 to rotate in the inclined direction of the inclined surface, that is, the trigger part 340 rotates away from the micro switch, preventing the trigger part 30 from triggering the micro switch 50 only when it approaches the micro switch 50 driven by the first action part 20.

[0044] Specifically in the embodiment, the electric tool further comprises a first rotating shaft 300 mounted on the first action member 20, and the trigger member 30 is rotatably mounted on the first rotating shaft 300. In this way, the trigger member 30 is rotatably connected.

[0045] Furthermore, the electric tool further comprises a first torsion spring (not shown) mounted on the first rotating shaft 300. The first torsion spring comprises a first torque arm and a second torque arm, the first torque arm being connected to the first operating member 20, and the second torque arm being connected to the triggering member 30, so as to provide a blocking force for blocking the triggering member 30 from rotating around the first rotating shaft 300 toward the triggering portion 340 approaching the micro switch 50. In this way, further, when only the first operating member 20 rotates and the second operating member 40 does not move, the triggering member 30 follows the first operating member 20 to move toward the micro switch 50, but the triggering portion 340 rotates away from the micro switch 50 under the action of the first torsion spring, thereby ensuring that in this case, the force acting between the triggering portion 340 and the micro switch 50 is small and the micro switch 50 will not be triggered.

[0046] In the embodiment of the present invention, the housing 10 includes a first handle 12 , the first action member 20 is rotatably connected to the first handle 12 , and the micro switch 50 is disposed on the first handle 12 .

[0047] In some embodiments, one end of the first action member 20 is rotatably connected to the first handle 12, and the trigger member 30 is rotatably connected to the other end of the first action member 20. In this way, the first action member 20 rotates a small angle relative to the first handle 12, which can drive the trigger member 30 to move a large distance closer to the micro switch 50, which is convenient for the operator to operate.

[0048] Specifically in the embodiment, the electric tool further includes a first elastic member (not shown) disposed between the first action member 20 and the first handle 12, and the first elastic member is used to provide a blocking force to block the end of the first action member 20 connected with the trigger member 30 from moving closer to the micro switch 50. In this way, after the external force is lost, the first action member 20 can be reset, that is, the first action member 20 drives the trigger member 30 to move away from the micro switch 50. Optionally, the first elastic member is a spring.

[0049] Specifically in the embodiment, the electric tool further comprises a second rotating shaft 220 mounted on the first handle 12, and one end of the first action member 20 is rotatably connected to the second rotating shaft 220 around the second rotating shaft 220. In this way, the first action member 20 is rotatably connected to the first handle 12 relative to the first handle 12.

[0050] Please continue to see Figure 2 As shown, in the embodiment of the present invention, the housing 10 further has a second handle 14 , and the second actuating member 40 is movably connected to the second handle 14 .

[0051] In some embodiments, the electric tool further includes a second elastic member (not shown) disposed between the second handle 14 and the second action member 40, and the second elastic member is used to provide a blocking force to block the second action member 40 from moving toward the second handle 14. In this way, when the external force is lost, the second action member 40 can return to the initial position under the action of the second elastic member. Optionally, the second elastic member can be a spring.

[0052] In the embodiment of the present invention, the electric tool further comprises a rotating block 42 rotatably connected to the housing 10. One end of the linkage member 60 away from the trigger member 30 is connected to the rotating block 42, and the second action member 40 is in conflict with the rotating block 42, so that during the movement of the second action member 40, the rotating block 42 can be driven to rotate, thereby driving the linkage member 60 to move. In this way, the second action member 40 drives the rotating block 42 to rotate, thereby driving the linkage member 60 to move. The structure is simple, and the consistency of the movements of each component is good.

[0053] In some embodiments, the second action member has an interference portion 400 that interferes with the rotating block 42 .

[0054] Specifically in the embodiment, the rotating block 42 includes an operating end 400 and a pulling end 422 relative to the operating end 400 . The connection voltage between the rotating block 42 and the shell 10 is between the operating end 400 and the pulling end 422 . The operating end 400 is in conflict with the interference part 400 , and the pulling end 422 is connected to the linkage 60 .

[0055] In some embodiments, the electric tool further comprises a third rotating shaft (not shown) mounted on the housing 10 , and the rotating block 42 is rotatably mounted on the third rotating shaft. In this way, the rotating block 42 is rotatably connected relative to the housing 10 .

[0056] Specifically in the embodiment, the second action member 40 further includes a second torsion spring (not shown) mounted on the third rotating shaft. The second torsion spring includes a third torque arm and a fourth torque arm, the third torque arm is connected to the rotating block 42, and the fourth torque arm is connected to the housing 10, so as to provide a blocking force to block the rotating block 42 from rotating around the third rotating shaft driven by the second action member 40.

[0057] In the embodiment of the present invention, the linkage member 60 is a pull cord. In this way, since the installation of the pull cord occupies a small space, the internal space of the power tool is further saved. In addition, since the pull cord has a low cost, it is helpful to reduce the cost of the power tool.

[0058] Specifically in the embodiment, the electric tool further includes a sleeve 62 fixedly mounted in the housing 10, and the pull cord is movably arranged in the sleeve 62 along the sleeve 62. In this way, the movement path of the pull cord is limited by the sleeve 62, so that the movement path of the pull cord driven by the second action member 40 each time remains unchanged, with good consistency, stable operation, and safety and reliability.

[0059] The following describes the status of the power tool in several situations:

[0060] Please continue to see Figure 1 When the first actuating member 20 and the second actuating member 40 are not in motion (i.e., neither the first actuating member 20 nor the second actuating member 40 is pressed), the trigger member 30 does not move toward the micro switch 50 and does not rotate. Therefore, the trigger portion 340 of the trigger member 30 does not contact the micro switch 50, and the micro switch 50 is not pressed and is in an off state. At this time, the electric tool is in a stopped state.

[0061] Please also see Figure 3When both the first actuating member 20 and the second actuating member 40 are in motion (i.e., both the first actuating member 20 and the second actuating member 40 are pressed), the first actuating member 20 rotates and drives the trigger member 30 to move closer to the micro switch 50, and the contact surface 342 of the trigger portion 340 contacts the micro switch 50. The second actuating member 40 moves, and the abutting portion 400 of the second actuating member 40 causes the rotating block 42 to rotate, thereby pulling the pull rope, and then the pull rope drives the trigger member 30 to rotate in the direction of the trigger portion 340 approaching the micro switch 50, so that the trigger portion 340 presses the micro switch 50, thereby triggering the micro switch 50 to turn on. At this time, the electric tool is turned on and is in working state.

[0062] Please also see Figure 4 When the first actuating member 20 is in motion and the second actuating member 40 is not in motion (i.e., the first actuating member 20 is pressed down and the second actuating member 40 is not pressed down), the first actuating member 20 rotates and drives the trigger member 30 to move closer to the micro switch 50, and the contact surface 342 of the trigger portion 340 contacts the micro switch 50. Since the trigger member 30 is rotatably connected to the first actuating member 20 and the contact surface 342 is tilted relative to the micro switch 50, the trigger portion 340 rotates with the trigger member 30 in a direction away from the micro switch 50. At this time, the acting force between the trigger member 30 and the micro switch 50 is limited and insufficient to trigger the micro switch 50. At this time, the electric tool is still in a shutdown state.

[0063] Please also see Figure 5 When the first actuating member 20 does not move and the second actuating member 40 moves (i.e., the first actuating member 20 is not pressed and the second actuating member 40 is pressed), the second actuating member 40 moves, and the abutting portion 400 of the second actuating member 40 causes the rotating block 42 to rotate, thereby pulling the pull rope to move, and the pull rope drives the trigger member 30 to rotate, so that the trigger portion 340 follows the trigger member 30 to rotate in the direction close to the micro switch 50. However, since the trigger member 30 does not move close to the micro switch 50 under the drive of the first actuating member 20, the trigger member 30 is far away from the micro switch 50. Even if the trigger member 30 rotates so that the trigger portion 340 is directly opposite to the switch, it cannot contact the micro switch 50 and cannot trigger the micro switch 50. At this time, the electric tool is still in a shutdown state.

[0064] Compared with the prior art, the present invention has the following advantages:

[0065] The electric tool of the present invention can realize double-action control with only one micro switch 50, which reduces wiring, simplifies the structure, and thus saves the internal space of the electric tool;

[0066] The trigger member 30 is driven by the first actuating member 20 and the second actuating member 40 to move and rotate toward the micro switch 50, thereby triggering the micro switch 50. The consistency of each component's action makes the power tool stable in operation. In other words, the micro switch is generally not triggered when only the first actuating member 20 or the second actuating member 40 is actuated; and the micro switch is not triggered when both the first actuating member 20 and the second actuating member 40 are actuated.

[0067] The linkage member 60 is a pull cord, which occupies little space when installed, further saving the internal space of the power tool. And since the pull cord has a low cost, it is helpful to reduce the cost of the power tool;

[0068] The moving path of the pull rope is limited by the sleeve 62, so that the path of the pull rope driven by the second action member 40 to move each time remains unchanged, with good consistency, stable operation, and safety and reliability.

[0069] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
