[0043] When the utility model is implemented, the first embodiment:

[0044] When using this device, the staff who use this device should

[0045] The overall structure includes a multi-stage telescopic rod 101, a controllable rotation mechanism 200 is provided at the end of the rod, and a hammer mechanism 300 is provided at the end of the controllable rotation mechanism 200. This design enables the device to be flexibly adjusted and accurately operated when in use.

[0046] In detail, the hammer mechanism 300 is composed of a middle connecting rod body 301 and hollow hammer heads 302 arranged at the ends of the rod body. The middle connecting rod body 301 is also provided with a connecting head 303. This connecting head 303 is fixedly connected to the controllable rotating mechanism 200 to ensure that the hammer mechanism 300 can achieve stable and precise rotation under the drive of the controllable rotating mechanism 200.

[0047] The structure of the controllable rotating mechanism 200 is more complicated, and it includes a bottom connecting plate 201, on which a side core plate 202 is provided, and a rotating sleeve 203 is provided on the upper side of the side core plate 202. A rotating shaft 204 is rotatably provided on the rotating sleeve 203, one end of the shaft is fixedly connected to the hammer mechanism 300, and the other end is fixedly provided with a limit plate 205, and a limit hole 206 is provided on the limit plate 205. In addition, the side core plate 202 is also provided with an internal sliding hole 207 and a long hole 208, and a columnar pin 209 is slidably provided in the internal sliding hole 207, and a toggle protrusion 210 and a compression spring 211 are provided at the end of the pin. This series of structural designs enables the controllable rotating mechanism 200 to achieve reliable rotation and fixation of the hammer mechanism 300.

[0048] The bottom connecting plate 201 is fixedly connected to the end of the multi-stage telescopic rod 101, so that the whole device can be operated stably. At the same time, the handle of the multi-stage telescopic rod 101 is provided with a rubber sleeve 102, which improves the comfort and stability of holding.

[0049] In actual use, the staff can extend the multi-stage retractable rod 101 as needed to adapt to different operating heights. At the same time, by switching two different hollow drum hammer heads 302, accurate knocking detection of hollow drums on the wall can be achieved. When it is necessary to switch the hammer head, the staff only needs to push the toggle protrusion 210 downward to disengage the columnar pin rod 209 from the limit hole 206, and then rotate the hammer body mechanism 300 to the desired position. After the switching is completed, the toggle protrusion 210 is released, and the compression spring 211 pushes the columnar pin rod 209 back to the limit hole 206 to achieve angle fixation.

[0050] Embodiment 2:

[0051] When using this device, the staff who use this device should

[0052] When using the hollow drum detection hammer device for civil engineering, the worker will first hold the handle of the multi-stage telescopic rod 101. Since the rubber sleeve 102 is specially designed for this part, the gripping feeling is more comfortable and stable, which not only improves the convenience of operation, but also greatly enhances the user experience.

[0053] Next, the staff will easily extend the multi-stage retractable rod 101 to a suitable length as needed. This multi-stage design is very practical because it allows the rod to reach a longer extension range, thereby adapting to the needs of various actual work scenarios.

[0054] After the preparation work is completed, the staff will choose to use one of the two different hollowing hammer heads 302 on the device to perform hollowing detection on the wall according to the actual situation. If a hammer head is stained with latex paint on the wall during use, affecting its normal use, the staff can easily switch to another clean hammer head to continue working. This design greatly improves the flexibility and efficiency of the tool.

[0055] When it is necessary to switch the hollow drum hammer head 302, the staff will operate the controllable rotating mechanism 200 on the device. Specifically, they will push the pushing protrusion 210 on the mechanism downward, which will compress the internal compression spring 211 and make the columnar pin 209 in the internal sliding hole 207 slide inward, so that it will be separated from the limiting hole 206 on the limiting plate body 205.

[0056] Once the columnar pin 209 is out of the limiting hole 206, the staff can easily rotate the hammer mechanism 300 to achieve a quick switch between the two hammer heads.

[0057] After the switch is completed, the staff only needs to release the toggle protrusion 210. At this time, the compression spring 211 will quickly return to its original state, push the columnar pin 209 to slide outward, and reinsert it into the corresponding limit hole 206, thereby ensuring that the hammer mechanism 300 is stably fixed in the new position, preparing for the subsequent hollow drum detection work.

[0058] The structure is novel and the design is unique, the gripping effect is better, the gripping is stable, comfortable, and very easy to use; the multi-stage retractable rod body 101 is multi-stage, which allows the multi-stage retractable rod body 101 to be extended to a longer length, which is convenient for use according to actual use conditions; according to actual use conditions, two different hollow drum hammer heads 302 are switched, and then the hollow drum hammer heads 302 are used to knock the hollow drums on the wall. Or when one of the hollow drum hammer heads 302 is stained with latex paint on the wall, it will affect the use of the hollow drum hammer head 302, so it can be switched to another hollow drum hammer head 302, which is convenient for use according to actual use conditions; the controllable rotating mechanism 200 is used, which is very convenient, stable and durable.

[0059] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
