detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the utility model and the utility model is not limited to the following examples.

Example.

Referring to Figures 1 to 2, the locking structure of the electric threading machine in this embodiment includes a locking spring 1, a cone head cover 2, a screw 3, a long sleeve 4, a sleeve 5, a threaded sleeve 6, and a locking head 7 And the locking handle 8, wherein the screw 3 is a hexagon socket head cap screw.

The locking head 7 in this embodiment is provided with a connecting hole, and an internal thread is arranged in the connecting hole, and one end of the screw 3 is threadedly connected in the connecting hole of the locking head 7, and the conical head cover 2 and the long sleeve 4 are all set. On the screw 3, one end of the long sleeve 4 abuts on the locking head 7, the other end of the long sleeve 4 abuts on one side of the conical head cover 2, and the other side of the conical head cover 2 abuts on the screw 3. on the screw head.

The sleeve 5, lock spring 1, threaded sleeve 6 and lock handle 8 in this embodiment are all set on the long sleeve 4, and one end of the lock spring 1 is pushed on the sleeve 5, and the lock spring 1 The other end is on the threaded sleeve 6, the sleeve 5, the threaded sleeve 6 and the locking handle 8 are arranged in sequence along the direction from one end of the long sleeve 4 to the other end of the long sleeve 4, and the locking handle 8 is located between the threaded sleeve 6 and the locking handle 8. Between the cone head cover 2.

Normally, the locking handle 8 is in contact with the conical head cover 2, and the position of the locking handle 8 in contact with the conical head cover 2 is a tapered groove structure.

The lock structure of the electric threading machine in this embodiment drives the lock head 7 to slide along the axial direction of the screw 3 through the force of the lock handle 8, that is, slides along the direction shown in FIG. 2, and the lock spring 1 shrinks. reach working condition.
