DETAILED DESCRIPTION

[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0021] See also Figures 1 to 4 In the embodiment of the utility model, a hammer with a detachable hammer head includes a hammer handle 1 and a hammer head 11 connected thereto, a horn 3 is provided on one side of the hammer head 11, a detachable hammer head cap 4 is installed on the other side of the hammer head 11, a hanging rope 2 is installed at the tail of the hammer handle 1, and the hammer head cap 4 is divided into three shapes: a metal round head 41, a rubber round head 42 and a hemispherical round head 43. According to different working conditions, a suitable hammer head cap 4 is selected and installed on the hammer head 1. The metal round head 41 is used to knock hard objects such as nails, the rubber round head 42 is used to knock objects that are easily damaged by knocks, such as floors, tiles, and glass, and the hemispherical round head 43 is used to knock hard objects such as nails, and the hemispherical round head 43 is used to knock hard objects such as floors, tiles, and glass. The spherical round head 43 is used to correct the bent structure and can be used to knock on metal plates. For example, in the process of making a silver pot, the hemispherical round head 43 is needed to be used for repeated knocking. A base 5 is arranged under the hammer head 11. The base 5 is an inverted T-shaped structure. The upper surface of the base 5 is respectively provided with a hammer placement groove 7 and a hammer head cap slot 6. The hammer head 11 is placed inside the hammer placement groove 7. There are two hammer head cap slots 6. Since there are three types of hammer head caps 4, one of which is installed on one side of the hammer head 11, and the extra two replaceable hammer head caps 4 are respectively clamped in the inside of the two hammer head cap slots 6.

[0022] Preferably, a mounting boss 9 is fixedly connected to the side surface of the hammer head cap 4 facing the hammer head 11, and the diameter of the mounting boss 9 is smaller than the diameter of the hammer head cap 4. A slot 8 is provided on the surface of the hammer head 11 facing the hammer head cap 4, and the mounting boss 9 is snapped into the inside of the slot 8. The surface of the hammer head cap 4 and the surface of the hammer head 11 abut against each other. A hard magnet 10 is fixedly provided on the inner bottom surface of the slot 8. The mounting boss 9 is made of one of the metals of iron, nickel, and cobalt. The length of the mounting boss 9 is smaller than the minimum vertical distance from the hard magnet 10 to the hammer head cap 4. When one of the hammer head caps 4 is installed to the side of the hammer head 11, the mounting boss 9 and the hard magnet 10 are close to each other, and the hard magnet 10 will generate a certain suction force on the mounting boss 9, thereby preventing the mounting boss 9 from falling off from the inside of the slot 8 when the hammer is used, and the need for replacement is avoided. When the hammer head cap 4 is installed, it is only necessary to manually apply a pulling force that is greater than the suction force of the hard magnet 10 on the mounting boss 9 to remove the mounting boss 9 from the inside of the slot 8, so that the hammer head cap 4 can be replaced conveniently to achieve suitability for different usage scenarios. When the hammer head cap 4 is striking the surface of an object, since the surface of the striking surface of the hammer head cap 4 and the surface of the hammer head 11 are against each other, and the mounting boss 9 and the hard magnet 10 are non-contacting, it is possible to avoid the mounting boss 9 from generating an impact force on the hard magnet 10 and causing damage to the hard magnet 10. Moreover, since the non-threaded or screw-threaded connection structure between the mounting boss 9 and the slot 8 is used, it is possible to avoid the force generated by the hammer with a traditional replaceable hammer head when striking to act on the thread or screw thread, thereby causing damage and deformation of the thread or screw thread, and causing inconvenience when subsequently replacing the hammer head cap 4.

[0023] The working principle of the utility model is: by setting three different hammer head caps 4, namely a metal round head 41, a rubber round head 42 and a hemispherical round head 43, the hammer head cap 4 can be replaced according to the working environment, and the replacement method is simple, and it is only necessary to pull the mounting boss 9 out of the slot 8, and through the attraction of the hard magnet 10 to the mounting boss 9, when the hammer is swung for striking, it is also possible to prevent the mounting boss 9 from sliding out of the inside of the slot 8, and a base 5 is also provided, which can be used to place two extra hammer head caps 4 to prevent the hammer head caps 4 from being lost, and a hammer placement groove 7 for placing the hammer head 11 is provided on one side of the base 5, and after using the hammer, the hammer head 11 can be placed in the hammer placement groove 7 for storage.

[0024] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
