[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1 , a rubber hammer for conveniently replacing the hammer head in this embodiment, which is used to increase the convenience of replacing the rubber hammer;

[0027] Specifically, it includes a handle 1, a hammer base 2, at least one rubber hammer head 3 and at least one locking component 4; the hammer base 2 is installed at one end of the handle 1, at least one rubber hammer head 3 is attached to one side of the hammer base 2, and a connecting pin 5 is installed on the side of the rubber hammer head 3 close to the hammer base 2; a positioning hole for inserting the connecting pin 5 is opened inside the hammer base 2, and at least one locking component 4 is arranged on the hammer base 2 to lock and fix the connecting pin 5.

[0028] During the actual use process, the connecting pin 5 on the rubber hammer head 3 is inserted into the corresponding positioning hole, and the connecting pin 5 is locked by the locking component 4, so that the connecting pin 5 is fixed in the positioning hole, and at the same time the rubber hammer head 3 is attached to one side of the hammer base 2. On the contrary, when it is necessary to replace the rubber hammer head 3, the connecting pin 5 can be released by operating the locking component 4, and then the connecting pin 5 can be taken out of the positioning hole, and at the same time the rubber hammer head 3 is separated from the hammer base 2.

[0029] In actual setting, by designing the detachable rubber hammer head 3 and the locking component 4, users can easily and quickly replace the damaged or worn hammer head without using special tools or complex operation steps, which greatly improves the work efficiency and use convenience. Since only the worn rubber hammer head 3 needs to be replaced instead of the whole rubber hammer, this design significantly reduces the maintenance cost during long-term use. Users can purchase and replace the hammer head separately according to needs, extending the service life of the whole tool.

[0030] Please refer to Figures 2-3, in order to realize the replacement and installation of the rubber hammer head 3, the locking component 4 in this embodiment includes at least four sliding grooves 401 opened inside the hammer base 2, as well as a clamping block 402 and a moving block 403 slidably connected inside the sliding grooves 401. At least four clamping blocks 402 are all attached to the outside of the connecting pin 5, and at least four moving blocks 403 are respectively slidably connected to one side of at least four clamping blocks 402 away from the connecting pin 5; a same collar 404 is fixedly sleeved outside at least four moving blocks 403, and a rotating member 405 rotatably connected to the collar 404 is threadedly connected to the outside of the hammer base 2, so that when the rotating member 405 rotates, it can drive the collar 404 and the moving block 403 to move left and right along the X-axis direction.

[0031] It should be noted that, in order to ensure that the rotating member 405 can drive the collar 404 and the moving block 403 to move left and right along the X-axis when rotating, and at the same time can drive the clamping block 402 to move back and forth in the Y-axis or Z-axis direction, the sides of the clamping block 402 and the moving block 403 that are in contact with each other are both inclined. A slide rail 406 is integrally formed on the side of the clamping block 402 close to the moving block 403; corresponding to the slide rail 406, a connecting groove adapted to the slide rail 406 is opened inside the moving block 403.

[0032] In actual setting, through the cooperation of the slide rail 406 and the connecting groove, that is, when the moving block 403 moves left and right along the X-axis direction, it will simultaneously slide on the outside of the slide rail 406, and the moving block 403 moves along the inclined surface direction of the clamping block 402, so as to drive the clamping block 402 to move back and forth in the Y-axis or Z-axis direction, so as to realize the fastening and release of the positioning bolt 5.

[0033] During actual installation, first insert the connecting pin 5 with the rubber hammer head 3 into the positioning hole, and then rotate the rotating member 405, so that the rotating member 405 drives the collar 404 to move towards the handle 1. The moving block 403 inside the collar 404 is driven to move along the X-axis direction inside the sliding groove 401. During the movement of the moving block 403, it pushes the clamping block 402 to move towards the connecting pin 5, so that at least four clamping blocks 402 are all tightly attached to the outside of the connecting pin 5, so as to realize the fixation of the connecting pin 5 and the rubber hammer head 3.

[0034] During actual replacement, if the rubber hammer head 3 needs to be replaced, just rotate the rotating member 405 in the reverse direction, the collar 404 and the moving block 403 will move away from the handle 1, and then push the clamping block 402 away from the connecting pin 5 through the inclined cooperation, realizing the unlocking and release of the rubber hammer head 3.

[0035] Further, in order to increase the stability of the connecting pin 5 in the positioning hole, the connecting pin 5 further includes a boss 501, which is integrally formed at one end of the connecting pin 5 away from the rubber hammer head 3, and the outer diameter of the boss 501 is larger than the outer side of the connecting pin 5, and the inner diameter of the positioning hole is adapted to the outer diameter of the boss 501.

[0036] In actual setting, by integrally forming the boss 501 at one end of the connecting pin 5 away from the rubber hammer head 3, and its outer diameter is larger than the main body part of the connecting pin 5, this enables the boss 501 to closely fit against the bottom or corresponding position of the positioning hole when the connecting pin 5 is inserted into the positioning hole, effectively preventing the connecting pin 5 from shaking or falling off when subjected to external forces, thereby enhancing the stability of positioning.

[0037] Moreover, the boss 501 increases the contact area between the connecting pin 5 and the positioning hole, thereby improving the connection strength between the two, helping to resist impacts and vibrations during use, and extending the service life of the rubber hammer.

[0038] Furthermore, in order to adapt to the shape of the outer surface of the connecting pin 5 and the boss 501, an arc-shaped groove adapted to them is provided on the side of the clamping block 402 close to the connecting pin 5 and the boss 501 in this embodiment, and at least four clamping blocks 402 are distributed in a circular array on the outer side of the connecting pin 5.

[0039] In actual setting, the design of the arc-shaped groove enables the clamping block 402 to fit and fix the connecting pin 5 more smoothly during movement, thus simplifying the installation process. Similarly, during disassembly, due to good shape matching, the clamping block 402 is also easier to release from the connecting pin 5, improving the convenience of disassembly. By distributing at least four clamping blocks 402 in a circular array on the outer side of the connecting pin 5, it is ensured that the connecting pin 5 can be evenly stressed when subjected to external forces, which helps to prevent deformation or damage caused by uneven stress, and improves the stability and reliability of the entire structure.

[0040] In addition, in order to ensure the stability of the clamping block 402 moving inside the sliding groove 401, the length and width of the clamping block 402 in the ZX plane in this embodiment are respectively adapted to the length and width of the sliding groove 401 in the ZX plane, and the length of the moving block 403 in the X-axis direction is half of the length of the clamping block 402 in the X-axis direction.

[0041] In actual setting, the length and width of the clamping block 402 in the ZX plane are adapted to the length and width of the sliding groove 401 in the ZX plane, ensuring that the clamping block 402 can slide smoothly inside the sliding groove 401, reducing friction and resistance caused by size mismatch. Due to the precise fit between the clamping block 402 and the sliding groove 401, the clamping block 402 is not prone to deviation or shaking during movement, thereby enhancing its stability when fixing the connecting pin 5.

[0042] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
