Description

Technical Field

[0001] The present application belongs to the technical field of electric tools, and in particular relates to a milling electric tool. Background Art

[0002] A router is a lightweight power tool for woodworking, commonly used for processes such as trimming, grooving, profiling, and rotary cutting. Routers typically have an operable trigger on the handle, which the user uses to start and stop the router. In some work scenarios, routers are mounted upside down below a workbench to perform grooving operations on workpieces placed on the workbench. When the router is upside down, the trigger that controls the motor is located below the workbench, forcing the user to constantly reach under the workbench to operate it. This is very inconvenient and can lead to fatigue over time. Utility Model Content

[0039] The present application will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present application.

[0041] like Figure 1 As shown, an electric milling machine 10 provided in one embodiment of the present application includes a main housing 11, a motor 12 disposed within the main housing 11, a chuck 17 capable of mounting different types of milling cutters, a power cord 13 for providing power, and dual handles 14 for a user to hold during operation. A switch assembly 15 is disposed on one of the handles, and the switch assembly 15 includes a switch trigger 151. When the electric milling machine 10 is in an upright position, the electric milling machine 10 is in an operating mode. The user operates the switch trigger 151 to move the machine to a working position, in which the switch assembly 15 is triggered and activated, driving the motor 12, thereby rotating the chuck 17 and the milling cutter to perform trimming, grooving, and other operations on the workpiece.

[0042] When the router 10 is inverted, it enters another operating mode. The handle 14 is provided with an operating member 16. The user operates the switch trigger 151 to move it to the working position, activating the switch assembly 15 and placing it in a normally closed state. At this point, the user can control the start and stop of the machine by turning the power cord on and off with the power outlet.

[0043] like Figure 2-4 As shown, in one embodiment of the present application, the operating member 16 includes a push rod 161 and a clamping portion 162, and an insertion portion 143 and a matching portion 144 are provided on the handle. The operating member push rod 161 enters the interior of the handle through the insertion portion 143, and the operating member clamping portion 162 is clamped with the matching portion 144 to ensure that the operating member 16 is stably installed on the handle 14.

[0044] Optionally, the handle insertion portion 143 is a square notch formed on the handle housing, and the operating member push rod 161 is a rod-shaped structure that can pass through the notch.

[0045] like Figure 5-7As shown, in one embodiment of the present application, a locking mechanism 141 is provided in the handle 14; when the operating member 16 is installed on the handle 14 and the switch trigger 151 is triggered to move from the initial position to the working position, the locking mechanism 141 maintains the working position of the switch trigger 151 so that the switch assembly 15 is in a normally closed state.

[0046] Specifically, the locking mechanism 141 includes a top block 1411 and a second elastic member 1413 connected to the top block 1411; the switch trigger 151 includes a top connection portion 1511 and a top block groove 1512 adjacent to the top connection portion; when the operating member 16 is installed on the handle 14, the operating member 16 drives the locking mechanism 141 to drive the top block 1411 to move toward the switch trigger 151, so that the top block 1411 docks with the top connection portion 1511, and the second elastic member 1413 is pressurized to bias the top block 1411 toward the top connection portion 1511; when the switch trigger 151 is triggered, the top connection portion 1511 is driven to move to disengage from the docking with the top block 1411, and the top block 1411 further moves under the restoring force of the second elastic member 1413 to engage with the top block groove 1512, thereby keeping the switch trigger 151 in the working position.

[0047] The locking mechanism 141 also includes a main body 1412, which defines a first accommodating cavity 14121 for accommodating the second elastic member 1413. The portion of the top block 1411 located within the first accommodating cavity 14121 is connected to the second elastic member 1413, while the portion of the top block 1411 that abuts the top connection portion 1511 is located outside the first accommodating cavity 14121. When the operating member 16 is mounted on the handle 14, the operating member 16 drives the main body 1412 to move, which in turn drives the top block 1411 toward the switch trigger 151.

[0048] Optionally, the portions where the top block 1411 and the top connection portion 1511 are connected to each other are inclined surfaces. When the switch trigger 151 is triggered, the inclined surfaces guide the top connection portion 1511 to move to disengage from the top block 1411 .

[0049] In one embodiment, the locking mechanism 141 includes a third elastic member 1414. When the operating member 16 is mounted on the handle, the operating member 16 drives the locking mechanism 141, causing the top block 1411 to move toward the switch trigger 151. The third elastic member 1414 is compressed, thereby biasing the locking mechanism 141 away from the switch trigger 151. When the operating member 16 is detached from the handle, the third elastic member 1414 returns to its original position, thereby driving the locking mechanism 141 to move the top block 1411 away from the switch trigger 151. The handle 14 internally includes a housing member 145, and the third elastic member 1414 is connected to the housing member 145.

[0050] Optionally, the locking mechanism 141 includes a main body 1412, the main body 1412 has a second accommodating cavity 14122 for accommodating the third elastic member 1414, and the shell element 145 passes through the second accommodating cavity 14122; in the second accommodating cavity 14122, one end of the third elastic member 1414 is connected to the shell element 145, and the other end of the third elastic member 1414 is connected to the main body 1412.

[0051] Optionally, there are multiple shell elements 145, and some of the shell elements 145 are fixedly arranged around the main body 1412 to position the main body 1412 in the handle, while limiting the main body 1412 to move only in a direction perpendicular to the direction of movement of the switch trigger.

[0052] like Figure 8-9 As shown, in one embodiment of the present application, a cover 142 and a first elastic member 1421 connected to the cover are provided inside the handle. The cover 142 covers the entrance of the insertion portion 143 under the biasing force of the first elastic member 1421, preventing dust, water and other liquids from entering the interior of the handle, thereby avoiding damage to the components inside the handle; during the process of installing the operating part to the handle, the push rod 161 drives the cover 142 to overcome the biasing force of the first elastic member 1421 and move, thereby allowing the push rod 161 to enter the interior of the handle.

[0053] Optionally, the first elastic member 1421 is a torsion spring.

[0054] like Figure 10-11 As shown, in one embodiment of the present application, the locking mechanism 141 is provided with a first guide bevel 14151, and the operating member 16 is provided with a second guide bevel 1611; when the operating member 16 is installed on the handle, the second guide bevel 1611 of the operating member 16 abuts and slides with the first guide bevel 14151 of the locking mechanism to drive the locking mechanism 141 to move toward the switch trigger 151.

[0055] Optionally, the locking mechanism 141 includes a main body 1412, the main body 1412 includes a push block 1415, the push block 1415 is provided with a first guide bevel 14151, and the operating member 16 includes a push rod 161, the push rod 161 is provided with a second guide bevel 1611; when the operating member 16 is installed on the handle 14, the second guide bevel 1611 of the push rod 161 abuts and slides with the first guide bevel 14151 of the push block 1415 to drive the push block 1415 to move toward the switch trigger 151.

[0056] The utility model utilizes an operating member that can be optionally installed on the handle, so that when the milling power tool is working inverted, the switch component can be in a normally closed state, and the start and stop states of the tool can be changed by turning the power on and off. The operator does not have to bend down to control the switch trigger located under the workbench, thereby improving the operating convenience and user experience.
