[0036] As Figures 1 to 6 shown, a pressing plate pencil-style compass includes a bracket 1. The bracket 1 includes a first leg 11 and a second leg 12 that are rotatably connected at the top end. The bottom end of the first leg 11 is provided with a needle tip 13. A sleeve 2 is provided on one side of the second leg 12. A pressing plate 3 is provided on the sleeve 2. The pressing plate 3 is rotatably connected to the sleeve 2. A pressing head 4 is provided on the side of the first end 31 of the pressing plate 3 close to the sleeve 2. An anti-slip member 41 is provided on the side of the pressing head 4 close to the sleeve 2. The sleeve 2 is provided with a pressing hole 5 corresponding to the pressing head 4 to limit the pressing head 4 from moving away from the sleeve 2;

[0037] In this embodiment, the anti-slip member 41 is a single spike. In other preferred embodiments, the number of spikes can also be increased to enhance the fixing effect of the anti-slip member, and it can be adjusted according to the actual situation;

[0038] In this embodiment, the sleeve 2 is provided with a slit 21, and the slit 21 communicates with the pressing hole 5. Due to the arrangement of the slit 21, a pressing head 4 with a size greater than or equal to the pressing hole 5 can be designed, so that the pressing hole 5 clamps the pressing head 4, thereby restricting the pressing head 4 from moving away from the sleeve 2;

[0039] In other preferred embodiments, no slit 21 is provided on the sleeve 2. At this time, to ensure that the indenter 4 can be restricted, the cross-sectional area of the indenter 4 becomes smaller as it gets closer to the sleeve 2.

[0040] An elastic member 6 is provided at the second end 32 of the pressing plate 3. The rotatable connection between the pressing plate 3 and the sleeve 2 is located between the indenter 4 and the elastic member 6. The elastic member 6 applies an elastic force away from the sleeve 2 to the first end 31. The function of the elastic member 6 is to cooperate with the indenting hole 5 to clamp the indenter 4 to achieve more stable restriction of the pencil 7.

[0041] In this embodiment, the elastic member 6 is a spring. A first spring groove 33 is provided on the pressing plate 3, and a second spring groove 22 is provided on the sleeve 2.
