Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.

As shown in fig. 1, 2 and 3, the utility model provides a wear-resistant hammer head, which comprises a hammer handle 1, wherein a groove is formed at the bottom of the hammer handle 1, a connecting rod 3 is fixed in the groove, a hammer head body 4 is rotatably connected to the connecting rod 3, the hammer head body 4 is provided with four hammer faces distributed in a rectangular array, and the hammer face at the bottom of the hammer head body 4 is positioned below the groove; a group of screw holes 43 distributed in a rectangular array are formed in the hammer head body 4, and a bolt 6 in threaded connection with the screw holes 43 is in threaded connection with the hammer handle 1; the hammer handle 1 is also provided with a mounting hole 2 positioned above the groove.

As shown in fig. 1 and 2, the one side that the recess deviates from bolt 6 on the hammer handle 1 is the open-type, the open one side of recess is equipped with baffle 5, set up the perforation that supplies connecting rod 3 one end to pass on the baffle 5, the cover is equipped with threaded connection and the lantern ring 51 that the one side that deviates from tup body 4 with baffle 5 supported on the connecting rod 3. The axle center of the hammer head body 4 is provided with a hole for the connecting rod 3 to pass through, when four hammer faces of the hammer head body 4 are worn, the baffle 5 and the connecting rod 3 can be separated by taking down the lantern ring 51, then the hammer head body 4 and the connecting rod 3 are separated, and after the new hammer head body 4 is replaced, the baffle 5 and the lantern ring 51 are restored; the baffle 5 can block the tup body 4, increases the stability that the tup body 4 was fixed in 1 recess of hammer handle.

As shown in fig. 1, 2 and 4, a slot 21 is formed in a side of the hammer handle 1 away from the bolt 6, a positioning hole 22 is formed in the slot 21, an L-shaped plate 52 inserted into the slot 21 is fixed to the top of the baffle 5, and a positioning rod 53 in threaded connection with the positioning hole 22 is connected to the L-shaped plate 52. After the L-shaped plate 52 is inserted into the slot 21, the positioning rod 53 is in threaded connection with the positioning hole 22, so that the L-shaped plate 52 can be fixed, and the firmness of the baffle 5 is improved; the positioning rod 53 is connected with the L-shaped plate 52 by screw threads.

As shown in fig. 1 and 2, concave holes 41 are formed in four hammer faces of the hammer head body 4, threaded screws 23 penetrate through two sides of the hammer handle 1, and a limiting block 24 matched with the concave holes 41 is fixed at one end, located in the groove, of each screw 23.
