Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in figures 1 and 2, a detachable crusher hammer head comprises a hammer handle 1 rotatably mounted on a rotating shaft and a hammer head 2 arranged at the bottom of the hammer handle, wherein the connection structure of the hammer handle 1 and the hammer head 2 is a detachable structure, a connection sleeve 3 is fixed on the hammer head 2, a plurality of arc-shaped elastic plates 4 are fixed on the circumference of the top of the connection sleeve 3, the arc-shaped elastic plates 4 are distributed in a circular shape, the outer surface of each arc-shaped elastic plate 4 is a conical surface, the hammer handle 1 is inserted into the connection sleeve 3, a locking sleeve 5 is connected to the outer thread of the connection sleeve 3 in a threaded manner, the locking sleeve 5 is sleeved on the hammer handle 1, and a threaded section 6, a conical cylinder section 7 and a straight cylinder section 8 are arranged in the locking sleeve 5, the threaded section 6 is fixed on the connecting sleeve 3, the conical cylinder section 7 is sleeved outside the arc-shaped elastic plate 4 and extrudes the arc-shaped elastic plate 4 on the hammer handle 1, and the straight cylinder section 8 is sleeved on the hammer handle 1.

The utility model discloses press from both sides tightly through the arc elastic plate between well tup and the hammer handle, when the installation, insert the hammer handle in the connecting tube, then through connecting the lock sleeve in adapter sleeve's outside. When the hammer is installed, the conical barrel section in the locking sleeve extrudes the arc-shaped elastic plate, so that the arc-shaped elastic plate is clamped on the hammer handle to realize fixation, and the fixation is simple and convenient.
