[0027] Embodiment 1

[0028] As Figures 1-4 shown, the power tool in this embodiment is specifically a circular saw, which can perform cutting processing on the processing object. Conventionally, it is composed of a base plate body 10 and a main body 20 connected to the base plate body 10. The main body 20 is used to process the processing object and is generally composed of accessories such as a handle 21, a gear box 22, a protective cover 23, a housing 24, and a motor connected to each other. Among them, two adjusting mechanisms 30 are provided on the base plate body 10. The adjusting mechanisms 30 adjust the working depth and working angle of the main body 20 by adjusting the relative rotation angle between the main body 20 and the base plate body 10. That is, the positions and adjusting rotation directions of the two adjusting mechanisms 30 are different, thereby realizing the adjustment of the cutting angle and depth.

[0029] Here, the adjusting mechanism 30 includes adjusting plates 31a, 31b and a locking component. The locking component passes through the adjusting plates 31a, 31b and is connected to the main body 20. The adjusting plates 31a, 31b are both vertically arranged on the base plate body 10. Movement grooves 311 for the movement of the shaft 33 are provided on the adjusting plates 31a, 31b, and a plurality of locking teeth 312 at different heights are provided on one side of the movement groove 311. Here, the movement groove 311 is bent, and the locking teeth 312 form a serrated structure in the movement groove 311. The position of the adjusting plate 31a is used for depth adjustment, and the position of the adjusting plate 31b is used for angle adjustment.

[0030] Moreover, the locking assembly includes a button 32, a pin shaft 33, a locking member 34 and an elastic member 35. The locking member 34 is arranged on the pin shaft 33, and the elastic member 35 is arranged between the locking member 34 and the main body 20 of the machine. The locking member 34 is in abutting cooperation with the locking teeth 312, thereby restricting the continuous movement of the locking member 34 in the movement groove 311. Under the action of an external force, the button 32 can drive the pin shaft 33 to move against the elastic force of the elastic member 35 and make the locking member 34 disengage from the locking teeth 312. Here, the elastic member 35 adopts a spring structure.

[0031] Wherein, the locking assembly further includes a limiting member 36, which is arranged on the pin shaft 33 and used to limit the pin shaft 33 from disengaging from the adjusting plates 31a and 31b. The button 32 and the limiting member 36 are respectively arranged at the head and tail ends of the pin shaft 33 and are respectively located on the opposite sides of the adjusting plates 31a and 31b. The connection between the button 32 and the pin shaft 33 is detachable, such as a threaded connection, that is, the end of the pin shaft 33 has an external thread, and the inside of the button 32 has a threaded hole, thereby realizing the connection. Accordingly, the limiting member 36 is an open retaining ring structure here.

[0032] Moreover, a stepped surface 331 is arranged on the pin shaft 33, and the locking member 34 is pressed by the elastic member 35 and abuts against the stepped surface 331.

[0033] Here, a fixing seat 37 is further arranged on the locking assembly for angle adjustment. The fixing seat 37 is sleeved on the pin shaft 33, and the fixing seat 37 is fixedly connected to the main body 20 of the machine and / or the bottom plate body 10 through bolts 38. The elastic member 35 is arranged between the fixing seat 37 and the adjusting plate 31b, and the corresponding limiting member 36 abuts against the outside of the fixing seat 37.

[0034] When the utility model is in use, according to the requirements of depth adjustment or angle adjustment, press the button 32 in the corresponding locking assembly to make the locking member 34 disengage from the locking teeth 312. At this time, the relative angle between the bottom plate body 10 and the main body 20 of the machine can be adjusted, and then the depth or angle adjustment is realized. After the adjustment is completed, release the button 32. Under the action of the elastic member 35, the locking member 34 is pushed back to the locking teeth 312 to complete the locking.

[0035] The examples, embodiments and specific forms shown in the present utility model have been shown and described in detail in the drawings and the foregoing description, and should also be considered illustrative rather than restrictive. The description of specific features in one embodiment does not mean that those specific features must be limited to that one embodiment. The features of one embodiment can be used in combination with the features of other embodiments, which can be understood by those of ordinary skill in the art, whether explicitly stated or not. Exemplary embodiments have been shown and described, and all changes and improvements fall within the spirit of the present utility model and are expected to be protected.
