In the process of electric planing, since the side surface of the wooden board is usually straight, the side stop structure 3 is kept in contact with the wooden board during the process of the electric planer moving forward, so that the electric planer can move forward in a straight line for planing; in conjunction with the side stop fixing knob 33 and the side stop rod 31, the length of the side stop rod 31 can be adjusted, thereby adjusting the side spacing between the side stop plate 32 and the electric planer body 1. It should be noted that in some other embodiments, the side stop structure 3 can also be arranged on the electric planer body 1. In this example, the adjustment housing is made integrally with the shell of the electric planer body.
[0032] The side baffle rod 31 is an L-shaped rod, and one end of the side baffle rod 31 passes through the through hole on the adjusting shell 21. In this example, the through hole on the adjusting shell 21 passes through both sides of the adjusting shell 21, so that the length of the side baffle rod 31 is not restricted; the other end of the side baffle rod 31 faces downward; the downward end of the side baffle rod 31 is connected to the side baffle plate 32. The side baffle plate 32 is arranged as a vertical plane on the side close to the adjusting shell 21; it should be noted that the edge of the side baffle plate 32 is chamfered, so that the side baffle plate 32 can move forward more smoothly when it contacts with external wooden boards. A latch tooth is also arranged on the outside of the side baffle fixing knob 33, and a corresponding latch tooth is arranged at the position where the adjusting shell 21 is provided with the adjusting fixing knob 33. When the latch teeth of the two engage with each other, the rotation of the side baffle fixing knob 33 is restricted, and the side baffle fixing knob 33 can only be rotated when it is pulled out.

[0034] The gripping handle 222 is also provided with a rotation limiting protrusion 224; the upper surface of the adjusting shell 21 is provided with an arc groove 211 corresponding to the rotation limiting protrusion 224; the rotation limiting protrusion 224 is embedded in the arc groove 211, and in this example, the center of the arc groove 211 coincides with the axis of the adjusting handle 22, so that when the adjusting handle 22 is kept rotating, the rotation limiting protrusion 224 can always be located in the arc groove 211, and when the rotation limiting protrusion 224 rotates to the two ends of the arc groove 211, it can be blocked by the arc groove 211 to form a limit, so that the height difference of the adjusting base relative to the planer can be adjusted within a set range value.
[0035] A second spring 213 is provided between the adjusting bottom plate 23 and the adjusting housing 21 , and the second spring 213 provides a force for the adjusting base to move away from the adjusting housing 21 , presses the adjusting base downward, and reduces the vibration effect of the planing body on the adjusting base during planing.
[0036] The electric planer body 1 includes a housing 11, a motor 12 and a planer blade structure 13. The planer blade structure 13 is located on one side of the electric planer body 1 close to the adjustment structure 2.

A tool groove 134 for embedding the blade 133 is arranged on the tool holder 132. In this example, two tool grooves 134 are symmetrically arranged on the tool holder 132 about the axis to improve the efficiency of planing. A screw hole for clamping and fixing the blade 133 is arranged on the side of the tool groove 134. The blade 133 can be removed from the tool groove 134 to separate the tool holder 132 and the blade 133, and the blade 133 can be replaced or polished.
[0037] The housing 11 is also provided with a switch 14, a trigger 15 and a locking member 16 for controlling the start and stop of the motor 12; the switch 14 is fixedly arranged in the housing 11, and the trigger 15 is rotatably arranged in the housing 11, and the trigger 15 is arranged correspondingly to the switch 14; the locking member 16 is also rotatably arranged in the housing 11, and the locking member 16 is arranged correspondingly to the trigger 15; a positioning protrusion corresponding to the locking member 16 is arranged on the trigger 15, and when the locking member 16 is rotated to a certain angle range, the positioning protrusion on the trigger 15 abuts against the locking member 16, making it difficult for the trigger 15 to rotate, and when the locking member 16 is rotated to other angle ranges, the trigger 15 is released; in this example, the two ends of the locking member 16 extend from both sides of the housing 11 respectively, so that it is convenient to toggle the locking member 16 on both sides of the electric planer body 1 to lock the trigger 15.
[0038] During the implementation process, by setting the side baffle structure 3 on the adjustment structure 2, it is convenient to control the electric planer body 1 to complete the planing operation along a straight line. At the same time, the side distance between the side baffle plate 32 and the electric planer body 1 can be adjusted to control the distance between the planing part and the side baffle plate 32; by setting the sliding clamp 24, it is convenient to grade the height adjustment process of the adjustment base to improve the accuracy of the adjustment control; by setting the rotation limit protrusion 224 to cooperate with the arc groove 211 on the adjustment shell 21, the rotation angle of the adjustment handle 22 is limited, thereby limiting the adjustment height range of the adjustment base; by setting the two ends of the locking member 16 to extend outward from the two sides of the shell 11, it is realized to control and lock the trigger 15 of the electric planer body 1 on both sides of the electric planer body 1.
