[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a knocking hammer with a length adjustment function, including a sleeve 1, the inner wall of the sleeve 1 is slidably connected with a hammer handle 2, several tooth grooves 3 are opened on one side of the outer surface of the hammer handle 2, an adjusting component 4 is clamped inside the tooth groove 3, a threaded connection block 5 is installed at the top of the hammer handle 2, the surface of the threaded connection block 5 is threadedly connected with a hammer head 6, limit holes 7 are opened at both ends of the bottom of the hammer head 6, a limit post 8 is sleeved inside the limit hole 7, a sliding sleeve 9 is installed at the bottom of the limit post 8, a second buffer spring 10 is installed at the bottom of the sliding sleeve 9, the bottom of the buffer spring is installed with a fixed ring 11, and the sliding sleeve 9 and the fixed ring 11 form a buffer structure through the second buffer spring 10.

[0020] The adjusting component 4 includes a locking tooth 401 clamped inside the tooth groove 3, a connecting plate 402 is installed on one side of the locking tooth 401, a push-pull rod 403 is installed on one side of the connecting plate 402, a first buffer spring 404 is sleeved on one side of the push-pull rod 403, the connecting plate 402 and the first buffer spring 404 form a pulling structure through the push-pull rod 403, and an installation shell 405 is slidably connected to the surface of the connecting plate 402.

[0021] In this embodiment, as Figure 1As shown, the sliding sleeve 9 and the hammer handle 2 form a sliding structure; the design of the sliding structure enables the operator to flexibly adjust the vertical height of the sleeve 1 by pressing and retracting the sleeve 1, thereby driving the limit post 8 to freely splice, fix, and disassemble the hammer head 6, ensuring that the hammer head 6 can be conveniently replaced and is not prone to loosening during long-term knocking work.

[0022] In this embodiment, as Figure 2 shown, the tooth grooves 3 are evenly and equidistantly distributed on one side of the outer surface of the hammer handle 2; it allows the user to easily lock or adjust the length of the hammer handle 2 during use to adapt to different working requirements and usage scenarios, greatly enhancing the flexibility and efficiency of the work, enabling the hammer to provide the best operation experience and functional performance in different situations.

[0025] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, first, the operator drives the connecting plate 402 and the engaging teeth 401 to move horizontally by pulling the push-pull rod 403, so that the engaging teeth 401 and the tooth grooves 3 are quickly disengaged from the engaged state. At the same time, hold the hammer handle 2 or the hammer head 6 and pull or push to drive the hammer handle 2 to slide in and out of the sleeve 1, thereby realizing the adjustable length of the knocking hammer. After the adjustment is completed, directly release the push-pull rod 403. Under the action of the first buffer spring 404, the connecting plate 402 and the engaging teeth 401 can be easily automatically reset and engaged. At the same time, the design of the limit post 8 and the sliding sleeve 9 ensures that during long-term knocking use of the knocking hammer, the threaded connection between the hammer head 6 and the hammer handle 2 is not prone to loosening, which is beneficial to ensuring the appraisal quality and operation safety. When the hammer needs to be disassembled, replaced, or maintained, the sliding sleeve 9 can be pressed to drive the limit post 8 to slide out from the limit hole 7 for subsequent rotation and replacement of the hammer head 6. After the replacement is completed, the hammer head 6 can be automatically limited and fixed by releasing the sliding sleeve 9.
