Detailed Description

Referring to fig. 1, 2 and 3, the lettering tool comprises an operating table 1, wherein a strip-shaped hole 11 is formed in the operating table 1, a limiting rod 12 is slidably arranged in the strip-shaped hole 11, a roller seat 13 is arranged on the limiting rod 12, a roller 14 is rotatably arranged on the roller seat 13 through a shaft rod, a rod seat 15 is fixedly embedded in the roller seat 13, the limiting rod 12 is slidably inserted into the rod seat 15, and the limiting rod 12 and the rod seat 15 are fixedly connected through a positioning pin 16.

Referring to fig. 2 and 3, the roller seat 13 is provided with a first positioning hole 2, the rod seat 15 is provided with a second positioning hole 21 corresponding to the first positioning hole 2, and the positioning pin 16 slidably penetrates through the first positioning hole 2 and the second positioning hole 21.

Referring to fig. 2 and 3, a spring 22 is wound on the positioning pin 16, and two ends of the spring 22 are respectively fixed to the positioning pin 16 and the roller seat 13, so as to ensure the stability of the telescopic reset of the positioning pin 16.

Referring to fig. 2 and 3, the limiting rod 12 is provided with a positioning groove 23, and the positioning pin 16 is inserted into the positioning groove 23, so that the roller seat 13 can be conveniently mounted and dismounted, and can be conveniently replaced or periodically maintained.
