[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, building construction refers to engineering projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities. A hammer is an important tool used in the construction process of building engineering.
[0003] The hammers used in existing construction projects typically include a nail puller and a hammerhead, which only serve the purpose of pulling nails and striking, and have a relatively simple function. However, construction projects may require other tools such as saw blades and measuring rulers, which means that multiple tools need to be carried during construction. This poses an inconvenience when working at heights. Therefore, a multi-functional hammer for construction projects has been proposed. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a multi-functional hammer for construction engineering to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional hammer for construction engineering, including a handle, a connector fixedly connected to the front end of the handle, a hammer head fixedly connected to one outer surface of the connector, a nail-pulling head fixedly connected to the side of the connector away from the hammer head, a receiving groove formed on the inner surface of the handle, a connecting shaft fixedly passing through the rear side of the receiving groove on the inner surface of the handle, a knife, a saw blade, and a scale respectively rotatably mounted on the outer surface of the connecting shaft from bottom to top, a threaded tooth formed on the outer surface of the connecting shaft, a threaded sleeve threadedly connected to the threaded tooth of the connecting shaft, and one end of the threaded sleeve movably abutting against the surface of the scale.
[0006] Furthermore, a placement seat is fixedly connected to the bottom outer surface of the handle, and a placement groove is formed on the outer surface of the handle, extending into the interior of the placement seat. An L-shaped plate is movably inserted into the outer surface of the handle, and a fixing strip is fixedly connected to the bottom outer surface of the L-shaped plate. Limiting grooves are formed at both ends of the front-facing outer surface of the fixing strip. An installation groove is formed on the inner surface of the handle, and a spring is fixedly connected to the inner surface of the installation groove. A limiting block that matches the limiting groove is fixedly connected to the side of the spring facing the limiting groove.
[0007] Furthermore, gaskets are provided on the side of the saw blade that contacts the cutting tool and the scale, and between the cutting tool and the inner wall of the receiving groove.
[0008] Furthermore, the outer surface of the handle is provided with a through groove around the connecting shaft to allow the threaded sleeve to pass through.
[0009] Furthermore, the two ends of the handle are rectangular pillars, the middle end of the handle is cylindrical, and an anti-slip pad is provided on the surface of the cylindrical part of the handle.
[0010] Furthermore, the left and right outer surfaces of the limiting block are both smooth and inclined surfaces.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This construction project uses a multi-functional hammer.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1:
[0021] Please refer to the following: Figures 1-4 This utility model provides a technical solution: a multi-functional hammer for construction engineering, including a handle 1, a connector 2 fixedly connected to the front end of the handle 1, a hammer head 3 fixedly connected to one outer surface of the connector 2, and a nail-removing head 4 fixedly connected to the side of the connector 2 away from the hammer head 3. A receiving groove 5 is formed on the inner surface of the handle 1, and a connecting shaft 6 is fixedly inserted through the rear side of the receiving groove 5 on the inner surface of the handle 1. A cutting tool 8, a saw blade 9, and a scale 10 are rotatably mounted on the outer surface of the connecting shaft 6 from bottom to top. A threaded thread is formed on the outer surface of the connecting shaft 6, and a threaded sleeve 7 is threadedly connected to the threaded thread of the connecting shaft 6. One end of the threaded sleeve 7 movably abuts against the surface of the scale 10. Specifically, the user holds the handle 1 and aligns the nail with the nail-removing head 4. The nail is then pulled out, and the hammer is used to strike the nail through one end of the hammer head 3, thus achieving the basic function of a hammer. During construction, the threaded sleeve 7 can be loosened to allow the cutter 8, saw blade 9, and scale 10 to rotate on the connecting shaft 6. The cutter 8, saw blade 9, and scale 10 are rotated to a position 180 degrees from the receiving groove 5, and then the threaded sleeve 7 is tightened to ensure that the cutter 8, saw blade 9, and scale 10 are stably positioned on the connecting shaft 6 and cannot rotate. Depending on the actual construction needs, the cutter 8, saw blade 9, and scale 10 are selected for use. The cutter 8 is used to cut connecting ropes, the saw blade 9 is used to cut wood strips, and the scale 10 is used for measurement. Thus, multiple functions are integrated into one, realizing the multi-functionality of this hammer.
[0022] In this embodiment, a placement seat is fixedly connected to the bottom outer surface of the handle 1. A placement groove is formed on the outer surface of the handle 1, extending into the interior of the placement seat. An L-shaped plate 11 is movably inserted into the outer surface of the handle 1. A fixing strip 12 is fixedly connected to the bottom outer surface of the L-shaped plate 11. Limiting grooves 16 are formed at both ends of the front-facing outer surface of the fixing strip 12. An installation groove 13 is formed on the inner surface of the handle 1. A spring 14 is fixedly connected to the inner surface of the installation groove 13. A limiting block 15, which is adapted to the limiting groove 16, is fixedly connected to the side of the spring 14 facing the limiting groove 16. Specifically, after the nail remover 4 removes the nail, the L-shaped plate 11 can be pulled to disengage it from the top of the placement cavity. When the L-shaped plate 11 is pulled, the L-shaped plate 11... When plate 11 presses against the inclined part of limiting block 15, as L-shaped plate 11 moves, limiting block 15 moves toward the inside of mounting groove 13, and spring 14 deforms until limiting block 15 disengages from the inside of limiting groove 16. When limiting block 15 moves to a position corresponding to another limiting groove 16, spring 14 returns to its original position. Spring 14 drives limiting block 15 to insert into the inside of limiting groove 16, limiting L-shaped plate 11, thereby opening L-shaped plate 11 and positioning it in a suitable position. The user places nails inside the placement cavity for storage. When applying reverse force to L-shaped plate 11, the working principle is the same as above, until L-shaped plate 11 closes the placement cavity, making it convenient for the user to store the nails that need to be recycled.
[0023] In this embodiment, a gasket is provided on the side of the saw blade 9 that contacts the cutter 8 and the scale 10, and between the cutter 8 and the inner wall of the receiving groove 5. Specifically, the gasket acts as a barrier between the saw blade 9, the cutter 8 and the scale 10. When the threaded sleeve 7 is tightened, the friction between the saw blade 9, the cutter 8 and the scale 10 and the gasket reaches a large degree, thereby making it difficult for the saw blade 9, the cutter 8 and the scale 10 to rotate easily.
[0024] In this embodiment, the outer surface of the handle 1 is provided with a through groove around the connecting shaft 6 to allow the threaded sleeve 7 to pass through. Specifically, when the threaded sleeve 7 is rotated, the threaded sleeve 7 moves at the through groove, and the through groove provides a channel for the movement of the threaded sleeve 7.
[0025] In this embodiment, the two ends of the handle 1 are rectangular pillars, and the middle end of the handle 1 is cylindrical. The surface of the cylindrical handle 1 is provided with an anti-slip pad. Specifically, the cylindrical handle 1 is provided so that when holding the hammer, the hand contacts the cylindrical handle 1, and the anti-slip pad increases the friction when the hand holds the handle 1.
[0026] In this embodiment, the outer surfaces of the left and right sides of the limiting block 15 are both smooth and inclined surfaces. Specifically, by setting smooth and inclined surfaces, when force is applied to the L-shaped plate 11, the inner wall of the L-shaped plate 11 contacts the smooth and inclined surface of the limiting block 15, and the limiting block 15 moves closer to the interior of the mounting groove 13 by the force applied by the L-shaped plate 11 to the limiting block 15.
[0027] Working Principle: In use, during construction, the user holds the handle 1, aligns the nail puller 4 with the nail, pulls out the nail, and then strikes it with the hammer head 3, achieving the basic hammer function. During construction, the threaded sleeve 7 can be loosened, allowing the cutter 8, saw blade 9, and scale 10 to rotate on the connecting shaft 6. The cutter 8, saw blade 9, and scale 10 are rotated to a position 180 degrees with the receiving groove 5, and then the threaded sleeve 7 is tightened, ensuring the cutter 8, saw blade 9, and scale 10 are stably positioned on the connecting shaft 6 and cannot rotate. Depending on the actual construction needs, the cutter 8, saw blade 9, and scale 10 are selected for use. The cutter 8 cuts connecting ropes, the saw blade 9 cuts wood strips, and the scale 10 measures, thus integrating multiple functions into one, realizing the multi-functionality of this hammer.
[0028] After the nail is removed by the nail remover 4, the L-shaped plate 11 can be pulled to disengage it from the top of the placement cavity. When the L-shaped plate 11 is pulled, it presses against the inclined part of the limiting block 15. As the L-shaped plate 11 moves, the limiting block 15 moves toward the inside of the mounting groove 13, and the spring 14 deforms until the limiting block 15 disengages from the inside of the limiting groove 16. When the limiting block 15 moves to the position corresponding to another limiting groove 16, the spring 14 returns to its original position. The spring 14 drives the limiting block 15 to insert into the inside of the limiting groove 16, limiting the L-shaped plate 11. This opens the L-shaped plate 11 and positions it in the appropriate position. The user places the nail inside the placement cavity for storage. When the L-shaped plate 11 is subjected to reverse force, the working principle is the same as described above until the L-shaped plate 11 closes the placement cavity, making it convenient for the user to store the nails that need to be retrieved.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
