Technical Field
[0001] This invention relates to the field of electric planer technology, and more particularly to an electric planer. Background Technology
[0002] In traditional woodworking, planing is a fundamental and common operation that involves smoothing the surface of wood or shaping it into a specific form. Electric planers, driven by a motor, rotate the planer blades at high speed, enabling rapid planing and significantly improving work efficiency and processing precision compared to hand planing.
[0003] However, existing electric planers still have some limitations and inconveniences in use. For applications requiring precise control of planing depth and angle, traditional electric planers often fall short, necessitating the use of other auxiliary tools or multiple adjustments to achieve the desired results.

The electric planer in the above-mentioned literature has the following shortcomings: although it can meet certain usage requirements, it is insufficient for chamfering and planing, and it is prone to damaging the worktable during misoperation, requiring further improvement. Summary of the Invention

[0018] A connecting rod, one end of which is hinged to another adjusting rod, and the other end of which is slidably connected to the inner wall of the second connecting arm.
[0019] As a preferred embodiment of the present invention: the surface of the positioning disk is provided with circumferentially distributed angle scale lines, the center of the positioning disk is fixed with a central column, a connecting rope is connected to the central column, and a gravity ball is provided at the bottom end of the connecting rope.
[0020] As a preferred embodiment of the present invention: the electric planer body has a through hole, and sleeves are provided on both sides of the electric planer body. The two sleeves are located on the outer sides of the two ends of the through hole, and an installation rod is detachably installed in the through hole. The installation rod has a prism-shaped structure, and a connecting plate is fixed to one end of the installation rod. A limit baffle is installed on one end of the connecting plate, and the limit baffle is perpendicular to the bottom surface of the electric planer body.
[0021] As a preferred embodiment of the present invention: the mounting rod is slidably connected to the through hole, and the top of the sleeve is threadedly connected to a threaded knob for fixing the mounting rod.
[0022] As a preferred embodiment of the present invention: an observation port is provided on one side of the sleeve, and a distance scale line is provided on one side of the mounting rod, the position of the distance scale line being adapted to the observation port.
[0023] As a preferred embodiment of the present invention: the top of the ball seat is provided with a plurality of grooves, and the ball seat is used in conjunction with an anti-slip cap. A protruding post is provided on one outer wall of the anti-slip cap, and the anti-slip cap is detachably installed in the groove of the ball seat through the protruding post.
[0024] As a preferred embodiment of the present invention: a limiting plate is fixed inside the mounting bracket, the limiting plate is located on one side of the rotating seat, and based on the force of the spring, the outer wall of one side of the rotating seat is pressed against the surface of the limiting plate.
[0025] As a preferred embodiment of the present invention: a collection box is provided on one side of the base frame, a strip-shaped opening is provided on the top of the collection box, a slide plate is slidably connected inside the strip-shaped opening, a connecting pipe is installed on the slide plate, and one end of the connecting pipe is detachably installed on the chip discharge port of the electric planer body.
[0026] The beneficial effects of this invention are as follows:
[0027] This invention, by setting up structures such as the electric planer body and the base frame, allows for planing by holding the electric planer body in contact with the object to be planed, or by mounting the electric planer body in reverse on the base frame and moving the object to be planed on the electric planer body to achieve planing.
[0028] This invention, by setting up a support mechanism, can support the electric planer body when it is placed, so that the planer blade will not contact the worktable, thus preventing damage to the worktable due to misoperation. When planing is required, the support rod is deflected by the thrust, and the spring is deformed, so that the planer blade of the electric planer body can contact the object to be planed, thereby completing the planing operation.
[0029] When performing chamfering planing, this invention utilizes both sides of the two sliding ball support components to facilitate planing. Since the two ball seats have openings on adjacent sides, the object can better contact the sliding ball from the opening side, making it more suitable for chamfering planing. By setting an adjusting cylinder and adjusting rod, the relative position of the two sliding balls can be adjusted, thereby providing better support or performing chamfering operations.
[0030] This invention, by setting an angle adjustment component, can adjust the position of the two adjustment rods extending out of the adjustment cylinder and fix them with a fixing knob. Since the length of the first connecting arm is fixed and the clamps of the first and second connecting arms are fixed, while the connecting rods and the second connecting arm are slidably connected, when the two adjustment rods move, the position of the positioning plate deflects, thereby changing the position of the connecting rope on the angle scale line. Based on this change, when the two sides of the object to be chamfered are in contact with the two sliders, the two sides are kept parallel to the first and second connecting arms respectively, so that the degree of chamfering can be controlled according to the angle scale line, improving practicality.
[0031] This invention, by setting up a limiting baffle, a mounting rod, a threaded knob, and other structures, can adjust the position of the mounting rod inside the electric planer body and fix it with the threaded knob, thereby changing the position of the limiting baffle at the bottom of the electric planer body, so as to adjust the planing width and improve practicality.

[0039] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.
[0040] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0041] Example 1: An electric planer, such as Figure 1-6As shown, the device includes an electric planer body 1, with a planer blade 3 disposed at the bottom of the electric planer body 1. The electric planer body 1 contains a motor for driving the planer blade 3. In this embodiment, preferably, the motor is an external rotor motor. The electric planer body 1 is provided with an adjustment knob 33 for adjusting the planer blade 3, and the bottom of the electric planer body 1 is provided with a strip-shaped groove. The driving and adjustment of the planer blade 3 can employ conventional existing technologies, which will not be elaborated upon here.
[0042] The electric planer body 1 is used in conjunction with a base frame 4. The electric planer body 1 has an assembly hole 27 on its side. The electric planer body 1 is detachably mounted on the base frame 4 in reverse by bolts. The electric planer body 1 and the base frame 4 cooperate to form a planing table structure.
[0043] A support mechanism is installed on the electric planer body 1, and the support mechanism includes:
[0044] Mounting bracket 9 is installed at the tail of the electric planer body 1. A support shaft is installed on the mounting bracket 9, and a mounting plate 24 is installed on the support shaft.
[0045] Rotary seat 25 is rotatably mounted on the outside of the support shaft, and the rotating seat 25 and the mounting plate 24 are connected by a spring 23;
[0046] A support rod is provided at the top of the support rod, and a ball seat 18 is provided at the top of the ball seat 18. A slider 22 is movably installed inside the ball seat 18. An opening is provided on the adjacent side of the two ball seats 18. The volume of the slider 22 enclosed in the ball seat 18 is more than one-quarter. The center of the slider 22 is located inside the ball seat 18.
[0047] By setting up structures such as the electric planer body 1 and the base frame 4, it is possible to hold the electric planer body 1 in hand to contact the object to be planed and plan it as needed, or to install the electric planer body 1 in reverse on the base frame 4 and hold the object to be planed and move it on the electric planer body 1 to achieve planing.
[0048] By setting up a support mechanism, when the electric planer body 1 is placed, the support mechanism can be used to support it, so that the planer blade 3 will not contact the table surface, thus preventing damage to the table surface due to misoperation; when planing is required, the support rod is deflected by the thrust, and the spring 23 is deformed, so that the planer blade 3 of the electric planer body 1 can contact the object to be planed, so as to complete the planing operation.
[0049] Furthermore, when performing chamfering planing, the two sides of the support component can be used to facilitate planing. Since the two ball seats 18 have openings on adjacent sides, the object can better contact the ball 22 from the opening side, which is more suitable for chamfering planing.
[0050] To facilitate adjusting the position of the slider 22; such as Figure 3As shown, the support rod includes an adjusting cylinder 20 and an adjusting rod 19. The adjusting cylinder 20 is fixed on the rotating seat 25, and the bottom end of the adjusting rod 19 is slidably installed on the inner wall of the top of the adjusting cylinder 20. A fixing knob 15 for fixing the adjusting rod 19 is threadedly connected to one side of the inner wall of the adjusting cylinder 20.
[0051] By setting the adjusting cylinder 20 and the adjusting rod 19, the relative positions of the two sliding balls 22 can be adjusted, thereby providing better support or performing chamfering operations.
[0052] To better adjust the chamfer angle; such as Figure 2 , Figure 3 As shown, an angle adjustment assembly is installed on the adjusting rod 19, the angle adjustment assembly including:
[0053] The first connecting arm 10 is hinged to an adjusting rod 19;
[0054] Positioning disk 11, the positioning disk 11 is fixed to the end of the first connecting arm 10;
[0055] The second connecting arm 14 is fixed to the outer wall of one side of the positioning disk 11, and the second connecting arm 14 and the first connecting arm 10 form a 90° angle.
[0056] Connecting rod 16, one end of which is hinged to another adjusting rod 19, and the other end of which is slidably connected to the inner wall of the second connecting arm 14.
[0057] To facilitate judging the angle; such as Figure 2 As shown, the positioning disk 11 has circumferentially distributed angle scale lines on its surface, a central column is fixed at the center of the positioning disk 11, a connecting rope 13 is connected to the central column, and a gravity ball 12 is provided at the bottom of the connecting rope 13.
[0058] By setting an angle adjustment component, the positions of the two adjustment rods 19 extending out of the adjustment cylinder 20 can be adjusted and fixed by the fixing knob 15. Since the length of the first connecting arm 10 is fixed, the clamps of the first connecting arm 10 and the second connecting arm 14 are fixed, while the connecting rod 16 and the second connecting arm 14 are slidably connected. When the two adjustment rods 19 move, the position of the positioning plate 11 deflects, thereby changing the position of the connecting rope 13 on the angle scale line. Based on this change, when the two sides of the object to be chamfered come into contact with the two sliders 22, the two sides are kept parallel to the first connecting arm 10 and the second connecting arm 14 respectively, so that the degree of chamfering can be controlled according to the angle scale line, improving practicality.
[0059] To facilitate planing operations; such as Figure 4 , Figure 5As shown, the electric planer body 1 has a through hole, and sleeves 29 are provided on both sides of the electric planer body 1. The two sleeves 29 are located on the outer sides of the two ends of the through hole, and an installation rod 30 is detachably installed in the through hole. The installation rod 30 has a prism-shaped structure. A connecting plate 28 is fixed to one end of the installation rod 30, and a limit baffle 2 is installed on one end of the connecting plate 28. The limit baffle 2 is perpendicular to the bottom surface of the electric planer body 1.
[0060] To facilitate planing operations; such as Figure 4 , Figure 5 As shown, the mounting rod 30 is slidably connected to the through hole, and the top of the sleeve 29 is threadedly connected to a threaded knob 32 for fixing the mounting rod 30.
[0061] To facilitate planing operations; such as Figure 4 , Figure 5 As shown, an observation port is provided on one side of the sleeve 29, and a distance scale line 31 is provided on one side of the mounting rod 30. The position of the distance scale line 31 is adapted to the observation port.
[0062] By setting up structures such as the limiting baffle 2, the mounting rod 30, and the threaded knob 32, the position of the mounting rod 30 inside the electric planer body 1 can be adjusted and fixed by the threaded knob 32, thereby changing the position of the limiting baffle 2 at the bottom of the electric planer body 1, so as to adjust the planing width and improve practicality.
[0063] To improve the support effect; such as Figure 3 As shown, the ball seat 18 has multiple grooves 26 on its top. The ball seat 18 is used in conjunction with an anti-slip cap 17. A protruding post 21 is provided on one outer wall of the anti-slip cap 17. The anti-slip cap 17 is detachably installed in the groove 26 of the ball seat 18 through the protruding post 21.
[0064] By incorporating structures such as anti-slip caps 17, the structure can prevent slipping during support, thus ensuring its stability.
[0065] Example 2: In order to improve the reliability of the support, this example makes the following improvements based on Example 1: The mounting bracket 9 is fixed with a limiting plate 34 on the inner side. The limiting plate 34 is located on one side of the rotating seat 25. Based on the force of the spring 23, the outer wall of one side of the rotating seat 25 is pressed against the surface of the limiting plate 34.
[0066] By setting up structures such as the limiting plate 34, the rotating seat 25 can be unidirectionally limited. In conjunction with the spring 23, it ensures both the mobility of the rotating seat 25 and the supporting effect of the structure.
[0067] To facilitate the collection of discharged waste; such as Figure 1As shown, a collection box 6 is provided on one side of the base frame 4. A strip-shaped opening is provided on the top of the collection box 6. A sliding plate 5 is slidably connected inside the strip-shaped opening. A connecting pipe 7 is installed on the sliding plate 5. One end of the connecting pipe 7 is detachably installed on the chip discharge port 8 of the electric planer body 1.
[0068] By setting up structures such as the collection box 6 and the connecting pipe 7, one end of the connecting pipe 7 can be connected to the chip discharge port 8 of the electric planer body 1 as needed. During planing, the connecting pipe 7 and the collection box 6 are used to collect the flying chips, which improves environmental protection.
[0069] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
