[0024] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0025] like Figure 1-4 As shown, the present invention provides a technical solution: comprising a handle body assembly 1, a hammer head assembly 2 is fixedly mounted on the top of the handle body assembly 1, the handle body assembly 1 comprises a grip 101, a vertical groove 102 is formed on the top surface of the grip 101, a threaded vertical rod 103 is rotatably mounted in the vertical groove 102, and an adjustable inner handle 104 is threadedly sleeved on the threaded vertical rod 103;
[0026] The hammer head assembly 2 includes a concave seat 201, in which a rotating shaft 202 is rotatably installed in the groove of the concave seat 201, a rotating block 203 is fixedly sleeved in the middle of the shaft body of the rotating shaft 202, and a hammer body 204 is slidably installed on the top surface of the rotating block 203, and threaded vertical openings 207 are provided at both ends and the middle of the top surface of the hammer body 204. A fixing screw 208 is inserted into the threaded vertical opening 207 in the middle, and a mounting plate 209 is fixedly installed at a corner of the top of the front face of the concave seat 201, and a worm 210 is rotatably installed on the bottom surface of the mounting plate 209, one end of the rotating shaft 202 extends to the front front of the concave seat 201, and a worm gear 212 is fixedly sleeved on one end of the extended rotating shaft 202, and the worm gear 212 is meshed with the worm 210, and the concave seat 201 is fixedly installed on the top surface of the adjusting inner handle 104.
[0027] In this embodiment, threaded interfaces 205 are provided on both end surfaces of the hammer body 204 , and striking hammer heads 206 are threadedly mounted on both ends of the hammer body 204 through the threaded interfaces 205 .
[0028] A threaded fixing opening is provided in the middle of the top surface of the rotating block 203 , and the bottom end of the fixing screw 208 is threadedly inserted into the threaded fixing opening, so that the hammer body 204 can be fixed on the top surface of the rotating block 203 .
[0029] The adjusting inner handle 104 is slidably inserted in the vertical groove 102, and a limiting opening 105 is opened on the top of one side of the adjusting inner handle 104. The bottom end of the worm 210 is fixedly installed with a rotating head, and a locking screw 211 is threadedly inserted into the side of the rotating head. The locking screw 211 corresponds to the limiting opening 105, and one end of the locking screw 211 is threadedly inserted in the limiting opening 105, making the structure more stable and effectively limiting the rotation of the handle body assembly 1.
[0030] The bottom end of the threaded vertical rod 103 extends to below the bottom surface of the handle 101, and a knob is fixedly installed at one end of the threaded vertical rod 103. By manually rotating the threaded vertical rod 103, the adjustment inner handle 104 can be moved in the vertical slot 102, so that the length of the adjustment inner handle 104 protruding from the vertical slot 102 can be conveniently controlled, and the length of the handle body assembly 1 of the striking hammer can be conveniently controlled.
[0031] Working principle: The striking hammer head 206 can be installed and disassembled as needed. Specifically, the striking hammer head 206 can be manually rotated to disconnect it from both ends of the hammer body 204. After disconnection, the screw provided at one end of the replaced striking hammer head 206 can be connected to the threaded interface 205 opened on the two end surfaces of the hammer body 204. At the same time, the length of the handle body assembly 1 of the striking hammer can also be conveniently changed. Specifically, the threaded vertical rod 103 is manually rotated. By rotating the threaded vertical rod 103, the adjusting inner handle 104 can be moved in the vertical slot 102, so that the length of the adjusting inner handle 104 protruding from the vertical slot 102 can be conveniently controlled, and then the length of the handle body assembly 1 of the striking hammer can be conveniently controlled.
[0032] At the same time, when it is necessary to carry the hammer, the locking screw 211 can be manually rotated to disengage one end of the locking screw 211 from the limit opening 105. After disengagement, the worm 210 can be manually rotated. The rotation of the worm 210 can drive the worm gear 212 to rotate. The rotation of the worm gear 212 can drive the rotating shaft 202 to rotate. The rotation of the rotating shaft 202 can drive the rotating block 203 to rotate. By rotating the rotating block 203, the hammer body 204 can be rotated from a horizontal position to a vertical position, so that it and the hammer head assembly 2 and the handle body assembly 1 are perpendicular to each other. The hammer 204 is in a parallel state, and then the fixing screw 208 is manually rotated to remove the fixing screw 208. The hammer body 204 is then manually controlled to move downward. After it moves downward a certain distance, the fixing screw 208 is re-connected to the threaded vertical opening 207 opened on one side of the top surface of the hammer body 204, and the fixing screw 208 is reconnected to the threaded fixing opening on the top surface of the rotating block 203. After the connection, the striking hammer head 206 can be overlapped with the handle 101, which makes it convenient for the user to rotate and fold the hammer head assembly 2, making it convenient to store and carry the striking hammer.
[0033] In summary, the portable percussion hammer can conveniently install and disassemble the percussion hammer head 206 as needed, which is convenient for replacing the old and damaged percussion hammer head 206, thereby improving the overall service life of the percussion hammer. At the same time, the length of the inner handle 104 protruding from the vertical slot 102 can be adjusted according to the needs of the percussion position, thereby conveniently controlling the length of the handle body assembly 1 of the percussion hammer. Furthermore, the hammer head assembly 2 can be conveniently rotated and folded up, thereby effectively changing the shape of the percussion hammer, making it convenient for staff to carry the percussion hammer, and being more practical.
[0034] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
