Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering tools, and particularly relates to a multifunctional hammer for construction engineering. Background Technique

[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation of pipelines and equipment supporting them. Among them, housing buildings refer to buildings with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet the needs of people's production, residence, study, and public activities. In construction engineering, it is often necessary to compact the soil to build a more stable building. At this time, a claw hammer can be used to gently tap the soil surface to make it denser. However, many claw hammers used in engineering have only a single function. To complete a task, many tools are required. Sometimes, it is necessary to measure the objects or materials after being struck. Moreover, traditional hammers are prone to falling off the hand during use, posing a certain safety hazard to personal safety. Therefore, a multifunctional hammer for construction engineering is needed to integrate multiple functions, which is both convenient to operate and safe and reliable, so as to achieve the purpose of efficiently completing the project.

[0003] Currently, for the existing multifunctional hammers for construction engineering, in order to realize the function of a tool clamp on the hammer body, the hammer body is disassembled and movably connected through a pin shaft to realize the function of the tool clamp. However, when such a clamp body is used, due to its relatively wide front end, it is impossible to clamp in a small space, greatly increasing the limitation of tool use. Moreover, due to the protruding clamp handle at the hammer handle part, when the hammer handle is used, it is not convenient for the user's palm to fully hold the hammer handle, and it is easy to cause wear to the user's palm part, greatly reducing the use experience. For this reason, we propose a multifunctional hammer for construction engineering. Content of the Utility Model

[0026] Specifically, one end in the middle of the hammer body 1 is fixedly installed with a hammer handle 12. Circular through holes 33 are opened at the top and bottom of the end of the hammer handle 12. The two circular through holes 33 penetrate the hammer handle 12 and communicate with each other. A push groove 22 is opened on one side of the hammer handle 12. The push groove 22 communicates with the inside of the circular through hole 33. A serrated card slot 23 is arranged at the inner bottom end of the push groove 22. A push block 24 is arranged inside the push groove 22. An extension block 26 provided in the middle of the push block 24 extends into the push groove 22. A connecting rod 27 is fixedly welded to the end of the extension block 26. The connecting rod 27 is placed inside the circular through hole 33 and is slidably connected thereto. A Phillips screwdriver head 28 and a flat screwdriver head 29 are respectively arranged at both ends of the connecting rod 27. Serrated clamping plates 31 are slidably arranged on both sides of the extension block 26.

[0027] Specifically, a protrusion is arranged at the end of the hammer handle 12. One side of the end surface of the protrusion is fixedly provided with a wrench 15. An adjustment groove 16 is opened on one side of the wrench 15. A clamping plate 17 is slidably connected inside the adjustment groove 16. An adjustment block 20 is fixedly installed at one end of the clamping plate 17 extending into the adjustment groove 16. A screw rod 19 is movably connected inside the adjustment groove 16 through a bearing. The adjustment block 20 is spirally connected with the screw rod 19 through a threaded sleeve embedded inside.

[0031] Specifically, a jacking spring 5 is arranged between the two clamping rods of the tool clamp 3. Both ends of the jacking spring 5 are fixedly connected to the opposite sides of the two clamping rods of the tool clamp 3.

[0032] In this embodiment, under normal conditions, the two pliers rods of the tool pliers 3 are merged with each other, so that the jacking spring 5 is compressed and stored inside the pliers body storage groove 2, and the clamping block 6 is clamped inside the clamping groove 10 to ensure the clamping and fixing of the tool pliers 3 and improve the stability of the pliers body 3 during storage. The end cover 21 covers the end of the hammer handle 12. When the hammer body 1 needs to be used for knocking, just hold the hammer handle 12. However, when the tool pliers 3 need to be used for clamping, by pressing the top blocks 11 on both sides of the outside of one end of the hammer body 1, they are moved inside the clamping groove 10 to form extrusion on the clamping block 6, causing it to contract into the pliers rod of the tool pliers 3, thereby releasing the clamping state of the bottom pliers rod of the tool pliers 3. Under the action of the ejecting spring 9, the tool pliers 3 are ejected, so that the front end of the tool pliers 3 extends outside the pliers body storage groove 2, and the upper pliers rod is in the arc-shaped groove and is jacked up under the action of the jacking spring 5 for the user to use quickly. Such a design enables, during use, through the extension of the front end of the tool pliers, to facilitate the clamping of objects in a smaller space, and avoids the bulge formed by the pliers rod at the hammer handle 12, which makes it inconvenient for the user to grip during use and causes palm wear, effectively ensuring the user experience. When the wrench 15 needs to be used, remove the end cover 21, and by rotating the wave wheel 18, drive the screw rod 19 to rotate, and cooperate with the threaded sleeve and the adjusting block 20 to realize the driving of the clamping plate 17, so as to adjust the position of the clamping plate 17 according to the needs for use. When the saw blade 14 needs to be used, after removing the end cover 21, flip the saw blade 14 and turn it out from the inside of the saw blade storage groove 13 to make it in a horizontal state with the hammer handle 12 for the use of the saw blade 14. When disassembling or assembling cross-slot screws or flat-slot screws, by pressing the pressing block 25, it drives the serrated clamping plate 31 to slide inside the pressing groove 30, compresses the second clamping spring 32, so that the serrated clamping plate 31 disengages from the clamping with the serrated clamping groove 23, thereby achieving the purpose of releasing the clamping state. Then, according to the needs, push the push block 24 up or down to facilitate pushing the cross screwdriver 28 or the flat screwdriver 29 out of the circular through hole 33. Finally, release the pressing block 25, and under the action of the second clamping spring 32, push the serrated clamping plate 31 to form clamping with the serrated clamping groove 23 again, thereby ensuring its stability for the use of the cross screwdriver 28 or the flat screwdriver 29.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood 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.
