Detailed ways

The following are specific embodiments of the present utility model and are combined with the accompanying drawings to further describe the technical solution of the present utility model, but the utility model is not limited to these embodiments.

As shown in Figures 1 to 5, the utility model adopts the following technical solution: a bakelite milling device that can be switched between fast and slow speeds, including a bakelite milling body 2 and a top base 1, which are fixed on both sides of the bakelite milling body 2 The two guide components on the top base, the power cord 3 provided on the bakelite milling body 2, and the scale 9 provided on the bakelite milling body 2 through fixing bolts 10, and are located and rotated below the scale 9 On the scale dial 8 on the top base 1, the guide assembly is divided into a first guide assembly and a second guide assembly. The first guide assembly includes a first inner rod 5 vertically arranged on the top base 1, and is sleeved on the top base 1. The first outer rod 6 on the first inner rod 5, and the rotating nut 7 provided at the top of the first outer rod 6, and the inner cylinder 16 provided at the inner bottom of the first inner rod 5, and the first inner rod 5. 5, the first spring 15 in the first outer rod 6, the screw rod 18 fixed to the rotating nut 7, the push rod 17 in the first inner rod 5, and the first inner rod 5. There is a limit nut 19 inside 5 that matches the screw rod 18, and a fixing knob 13 provided on the first outer rod 6.

The second guide component includes a second inner rod 11 vertically disposed on the top base 1, a second outer rod 12 sleeved on the second inner rod 11, and a second spring disposed in the second inner rod 11. 14. One end of the second spring 14 is against the inner bottom of the second inner rod 11, and the other end of the second spring 14 is against the inner top of the second outer rod 12. The inner top of the second outer rod 12 is provided with a spring fixed strip.

One end of the push rod 17 is connected to the screw rod 18 , and the other end of the push rod 17 is located in the inner cylinder 16 .

The inner top of the first inner rod 5 is provided with two inwardly protruding limit blocks 51, and the limit nut 19 is provided with four upward limit grooves 1901. The limit grooves 1901 and The limiting block 51 matches.

The inner cylinder 16 and the push rod 17 are located in the first spring 15. One end of the first spring 15 is against the inner bottom of the first inner rod 5, and the other end of the first spring 15 is against the bottom of the limiting nut 19.

A handle 4 is provided on the outside of the first outer rod 6 and the second outer rod 12 .
