Detailed Description

The invention will be further illustrated with reference to the following specific examples.

Fig. 1 is a schematic structural diagram of a hammer provided in this embodiment, and the hammer is composed of an end cover 1, a first spring 2, a cylinder 3, a slider 4 with a hook, a bracket 5, a handle 6, a hammer 7, a second spring 8, a hammer head 9, a positioning taper sleeve 10, and the like.

The hammer 7 is mounted in the cylinder block 3 to be movable up and down along the cylinder block 3. The slide block with hook 4 is installed between the outer wall of the hammer 7 and the inner wall of the cylinder body 3, the inner wall of the cylinder body 3 is provided with a sliding groove, and the slide block with hook 4 can slide up and down along the sliding groove on the inner wall of the cylinder body 3. The upper and lower ends of the hooked slider 4 are provided with lateral hooks, and the hammer 7 is provided between the lateral hooks of the upper and lower ends.

The outer side of the slide block 4 with the hook is provided with a groove, the cylinder body 3 is also provided with a groove body corresponding to the groove, and the end part of the handle 6 penetrates through the groove body on the cylinder body 3 and is embedded into the groove on the slide block 4 with the hook. The hooked sliding block 4 can be driven to move up and down along the cylinder body 3 by operating the handle 6, and then the hooked sliding block 4 drives the hammer 7 to move. In order to enhance the fixing strength of the handle 6, a triangular bracket 5 is arranged on the outer wall of the cylinder body 3, the handle 6 is arranged on the bracket 5 through a pin, and the handle 6 can rotate up and down around the pin.

An end cover 1 is arranged at the top of the cylinder body 3, and a first spring 2 is arranged on the inner surface of the end cover 1. A hammer head 9 is arranged at the center of the bottom of the hammer 7, and the outer diameter of the hammer head 9 is smaller than that of the hammer 7; the lower end of the hammer 9 penetrates through the positioning taper sleeve 10, the upper end of the positioning taper sleeve 10 is provided with an internal thread, and the internal thread is connected with the external thread at the lower end of the cylinder body 3. The outside of the hammer head 9 at the upper end of the positioning taper sleeve 10 is sleeved with a second spring 8, and the second spring 8 is limited between the bottom of the hammer 7 and the upper end of the positioning taper sleeve 10.

The lower part of the positioning taper sleeve 10 is provided with an inwards concave tapered groove, and the diameter of the upper end of the tapered groove is smaller than that of the lower end of the tapered groove.

The use method of the hammer provided by the embodiment comprises the following steps:

the positioning taper sleeve 10 is sleeved at the upper end of a rod (nail) to be hammered, the end cover 1 above the cylinder body 3 is pressed by one hand, the handle 6 is pulled by the other hand to be pressed downwards, the handle 6 drives the hooked sliding block 4 to move upwards, and then the hooked sliding block 4 drives the hammer 7 to move upwards.
