[0022] The utility model will be explained in further detail below in combination with the drawings and embodiments.

[0023] The terms used in the utility model are merely for the purpose of describing specific embodiments, and are not intended to limit the utility model. For example, the words indicating the orientation or position relationship such as "upper", "lower", "front", "rear" and the like below are merely based on the orientation or position relationship shown in the drawings, and are merely for the convenience of describing the utility model and simplifying the description, and are not intended to indicate or imply that the indicated device / element must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0024] Please refer to Figures 1 to 5 The embodiment of the utility model relates to a trimmer 100 for trimming, slotting and other working operations on wood and other workpieces. The trimmer 100 comprises a trimmer main body 1, an adjusting device 2 mounted on the trimmer main body 1, and a gauge guide plate 6 provided in the adjusting device 2. The trimmer main body 1 comprises a housing 11, a transmission mechanism (not shown) mounted on the housing 11, a battery pack 12 driving the transmission mechanism, and a cutter 13 accommodated in the transmission mechanism. The adjusting device 2 is clamped on the outer circumferential surface of the housing 11. Under the action of the battery pack 12, the trimmer 100 drives the transmission mechanism to rotate. When the user performs the working operation, the adjusting device 2 of the trimmer abuts against the workpiece, and the trimmer is moved according to the required trajectory, so that the cutter 13 trims the working surface of the workpiece.

[0025] In the embodiment, the adjusting device 2 has a base main body 3 mounted on the trimmer main body 1, a connecting device 4 protruding from the base main body 3, and a bottom plate 5 mounted on the connecting device 4. The gauge guide plate 6 is mounted between the base main body 3 and the bottom plate 5 through the connecting device 4. The trimmer 100 can realize linear or curved cutting, slotting of various shapes, and other operations, and can realize the required jig style of the user.

[0026] Specifically, the connecting device 4 includes a first mounting part 41 protruding from the end face of the base body 3 and a first engaging part 42 protruding from the first mounting part 41. The base plate 5 includes a second mounting part 51 recessed from the end face and a second engaging part 52 recessed from the second mounting part 51. The first engaging part 42 and the second engaging part 52 are threadedly connected. Through a simple threaded nut fixing structure, the gauge guide plate 6 is installed between the base body 3 and the base plate 5. Moreover, the first mounting part 41 is engaged with the second mounting part 51, which can prevent the first engaging part 42 and the second engaging part 52 from vibrating and loosening when the trimming machine 100 is working, thereby playing a certain anti-rotation function.

[0027] Furthermore, the first engagement portion 42 is configured as an external thread section, and the second engagement portion 52 is configured as an internal thread section.

[0028] In addition, the base plate 5 also has a notch 54 recessed from the end face, and the connecting device 4 also includes a mounting part 43 formed from the periphery. When the first engaging part 42 is threadedly connected to the second engaging part 52, and the first mounting part 41 is engaged with the second mounting part 51, the notch 54 is flush with the mounting part 43, so as not to affect the subsequent installation of the guide rail by the user.

[0029] Please see Figure 4 and Figure 5 As shown, the first mounting portion 41 has a connecting portion 411 protruding from its outer edge, and the second mounting portion 51 has a mating portion 511 protruding from its inner edge and a stop portion 512 adjacent to the mating portion 511. One end of the connecting portion 411 abuts against the mating portion 511, and the other end abuts against the stop portion 512. This simple structure prevents the tool from vibrating and loosening during operation.

[0030] In this embodiment, the joint portion 411 includes an arcuate portion 4111 protruding from the outer edge of the first mounting portion 41, and the arcuate portion 4111 abuts against the stop portion 512 to form a lock between the two.

[0031] Specifically, the joint 411 also includes an upright portion 4112 formed by the arc-shaped portion 4111, which abuts against the mating portion 511.

[0032] Please refer to the following: Figure 4 and Figure 5 As shown, the stop portion 512 is configured in a semi-circular shape, and a closed gap 510 is formed between the stop portion 512 and the second mounting portion 51. Please refer to [reference needed]. Figure 4As shown, when the user rotates the bottom plate 5 clockwise, the engaging portion 411 is forced against the end face of the stop portion 512, and further gradually compresses the gap 510. After a required force is applied, the engaging portion 411 and the stop portion 512 are disengaged from each other, and only the first engaging portion 42 and the second engaging portion 52 need to be continuously rotated to achieve the replacement of the gauge guide plate 6. Conversely, when the user rotates the bottom plate 5 counterclockwise, the first engaging portion 42 and the second engaging portion 52 are connected, the engaging portion 411 is forced against the other end face of the stop portion 512, and further gradually compresses the gap 510. After a required force is applied, the engaging portion 411 and the stop portion 512 are engaged. It should be noted that the stop portion 512 has a certain elastic deformation amount, so that when the engaging portion 411 and the stop portion 512 are engaged, a "click" prompt sound is emitted.

[0033] In addition, in the present embodiment, the bottom plate 5 also has an operation portion 53 recessed from the outer edge, and the operation portion 53 is sawtooth-shaped. When the user rotates the bottom plate 5, the fingers can act on the operation portion 53, and the sawtooth-shaped structure increases the friction between the two, which facilitates better force application for replacing the gauge guide plate 6. The number of operation portions 53 is even and centrally symmetric, or covers the entire outer circumferential surface. In the present embodiment, the number of operation portions 53 is 2, but is not limited thereto.

[0034] The adjusting device 2 has a central axis 20, and the cooperating portion 511 and the stop portion 512 are arranged in one of the operation portions 53 to project within the central axis 20, which facilitates the user to better apply force at the cooperating portion 511 and the stop portion 512, and saves labor.

[0035] The utility model is not limited to the above specific embodiments. Those skilled in the art can easily understand that the trimming machine of the utility model has many alternative solutions without departing from the principles and scope of the utility model. The protection scope of the utility model is subject to the contents of the claims.
