[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model sets an alloy hammer head. When the hammer head needs to be adjusted, the adjusting wheel is rotated to drive the internal threaded barrel to rotate. The internal threaded barrel rotates to rotate the alloy hammer head inside and screws out downward. The adjusting wheel is continued to be rotated to gradually screw out the alloy hammer head. At this time, the hammer handle is swung to make the expansion slot contact with the object. Since the bottom surface of the expansion slot is smaller than the hammer head, the pressure on the object is greatly increased under the same force, thereby greatly improving the crushing efficiency, facilitating the use of users, and improving the practicality of the multi-functional hammer.

[0021] refer to Figures 1 to 4 The surface of the right end of the hammer handle 8 is provided with an external thread, and the surface of the hammer handle 8 is provided with a telescopic sleeve 10. A slide groove 11 is opened inside the telescopic sleeve 10. The round support 9 is slidably connected with the slide groove 11. The left side of the inner wall of the slide groove 11 is provided with an internal thread 12. The hammer handle 8 is threadedly connected with the internal thread 12, and the right end of the telescopic sleeve 10 is fixedly connected with an anti-slip block 13.

[0022] As a technical optimization scheme of the utility model, through the setting of the telescopic sleeve 10, the telescopic sleeve 10 is rotated to make the internal internal thread 12 rotate synchronously. The rotation of the internal thread 12 causes the hammer handle 8 to be gradually screwed out, and the hammer handle 8 is extended. Since the lever arm is proportional to the force, when the same force is used to hit the object, the hammer force it receives is greater, thereby further improving the crushing efficiency.

[0023] refer to Figures 1 to 4 A retaining ring 14 is sleeved on the bottom of the hammer head 1 surface.

[0024] As a technical optimization solution of the utility model, the setting of the retaining ring 14 can avoid the problem of debris splashing upward during crushing, thereby causing the debris to fly to the eyes and cause injuries to people.

[0025] refer to Figure 1 , Figure 3 and Figure 4 A convex strip 15 is fixedly connected to the surface around the adjusting wheel 5 .

[0026] As a technical optimization solution of the utility model, the friction between the adjusting wheel 5 and the hand is increased by setting the convex strip 15, so that the adjusting wheel 5 can be rotated more easily.

[0027] refer to Figures 1 to 3 The surface of the right end of the telescopic sleeve 10 is provided with an anti-skid groove 16 , and the surface of the anti-skid groove 16 is fixedly connected with an anti-skid sleeve 17 .

[0028] As a technical optimization solution of the present invention, the provision of the anti-slip sleeve 17 can prevent the hand from slipping with the telescopic sleeve 10 and causing the sleeve to fly out and cause a safety accident.

[0029] refer to Figure 4 An annular groove 18 is provided on the surface of the hammer head 1 , and a dust ring 19 is slidably connected inside the annular groove 18 , and the top of the dust ring 19 is fixedly connected to the adjusting wheel 5 .

[0030] As a technical optimization solution of the present invention, by providing the dust shield 19, flying debris and dust will not enter the interior of the bearing 3 and cause the rotation thereof to be blocked.

[0031] The working principle and use process of the utility model are as follows: when in use, when the user needs to adjust the hammer head 1, the user rotates the adjusting wheel 5 to drive the internal threaded tube 4 to rotate, and the internal threaded tube 4 rotates to rotate the alloy hammer head 6 inside and screws it downward, and continues to rotate the adjusting wheel 5 to gradually screw out the alloy hammer head 6, and then swings the hammer handle 8 to make the telescopic groove 7 contact with the object. Since the bottom surface of the telescopic groove 7 is smaller than the hammer head 1, under the same force, the pressure exerted on the object is greatly increased, thereby greatly improving the crushing efficiency, and the telescopic sleeve 10 can be rotated as needed to make the internal thread 12 inside it rotate synchronously, and the rotation of the internal thread 12 causes the hammer handle 8 to gradually screw out, and the hammer handle 8 is extended. Since the force arm is proportional to the force, when the same force is smashed down, the hammering force exerted on the object is greater, thereby further improving the crushing efficiency.
