The milling cutter is arranged on a rotating shaft of a lathe, a fixed nut needs to be rotated when the milling cutter is arranged, and the milling cutter is inconvenient to operate because a shaft for fixing the milling cutter rotates freely and a shell is not provided with a self-locking mechanism and two large wrenches and one small wrench are matched.
There are some casings that have self-locking mechanism at present, and specific structure constitutes: the self-locking spring consists of a spring, a self-locking shaft and a button, and the assembly mode is as follows: 1. installing the self-locking shaft into a pin shaft guide hole on the shell; 2. the spring is arranged on the upper surface of the cylinder inside the button; 3. the button provided with the spring is arranged in the circular cavity on the shell; 4. the tapered head on the self-locking shaft is pressed onto the button by using a tool. The button and the self-locking shaft adopt a mode of back-off connection. The specific shaft locking mode is that a button is pressed by a hand, one end of the self-locking shaft is pressed into a round hole on the shaft, the shaft cannot rotate, and the purpose of locking the shaft is achieved. Thus, the nut on the shaft can be screwed in and out by using a spanner. The existing self-locking structure has the following defects: when the nut is locked, the self-locking shaft enables the pin shaft guide hole on the shell to be acted by radial force for a long time. So that the lock shaft hole is easily deformed into a U-shaped hole. If the number of times of locking the shaft is large, the shaft is easy to fail. Moreover, the structure is only suitable for a metal structure, and if the structure is a plastic shell, the pin shaft hole of the self-locking structure is easier to deform and crack.
To sum up, for solving current problem, the utility model designs a simple structure, press convenient, lock effectual casing self-locking mechanism.
