Description

Technical Field

[0001] This utility model relates to the field of archaeological hammer technology, specifically to a multifunctional archaeological hammer. Background Technology

[0002] In archaeological excavation, the archaeological hammer is an indispensable tool. Existing archaeological hammers, such as the multi-purpose archaeological hammer disclosed in Chinese Utility Model Patent No. CN203918966U, include a hammerhead and a first and second handle fixed or hinged to the hammerhead. The first handle has length graduations, and the second handle has segmented angle graduations for displaying the angle between the first and second handles. The two handles hinged to the hammerhead together serve as both a handle and a measuring tool, offering versatility, portability, storage convenience, and ease of use. Furthermore, the inner edges of both the first and second handles are sharp blades, allowing them to be used as scissors.

[0003] Given the existing technology, since the inner sides of both the first and second rulers are sharp blades, when the first and second rulers are overlapped and used as a hammer handle, the sharp blades on the inner sides of the first and second rulers can easily injure the hands of archaeologists.

[0004] In view of this, this utility model proposes a multifunctional archaeological hammer to solve the above problems. Utility Model Content

A second handle is rotatably connected to the shaft. The first handle has length graduation lines, and the second handle has line segment angle graduation lines for displaying the angle between the first and second handles. The inner sides of both the first and second handles are sharp blades. A hammer handle is fixed to the first handle, and the hammer handle includes a grip. The grip has a slot, which extends through both ends of the hammer handle and the side near the second handle. The second handle can rotate into the slot, and the second handle is detachably connected to the slot.

[0007] Preferably, the outer surface of the grip is fixedly covered with a rubber sleeve, and the side of the rubber sleeve is provided with a finger grip groove.

[0008] Preferably, a magnet is fixed to the inner side of the slot.

[0009] Preferably, the inner side of the second handle ruler is provided with an L-shaped groove, the side of the handle is provided with a groove, an L-shaped locking block is slidably provided in the groove, a spring is connected to one end of the L-shaped locking block and the groove, an opening is provided through the groove on the side near the slot, and one end of the L-shaped locking block is movably disposed in the opening.

[0010] Preferably, the width of the slot is greater than the width of the first ruler and the second ruler.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a multi-functional archaeological hammer with a grooved hammer handle fixedly installed on the first handle. The second handle can be rotated into the groove and is detachably connected. When the first and second handles are used as hammer handles, the second handle can be stored in the groove to prevent the hand from being cut by sharp blades. At the same time, the handle is equipped with a rubber sleeve and a finger grip groove for easy gripping. The second handle is also limited in the groove by magnetic adsorption or by L-shaped blocks cooperating with L-shaped slots, making it safer and more convenient to use. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-3 .

[0018] Example 1 A multi-functional archaeological hammer includes a hammerhead 9, a first handle 7 fixedly connected to the hammerhead 9, and a shaft 8 fixedly connected to the hammerhead 9. A second handle 6 is rotatably connected to the shaft 8. The first handle 7 is provided with length scale lines, and the second handle 6 is provided with line segment angle scale lines for displaying the included angle between the first handle 7 and the second handle 6. The inner sides of both the first handle 7 and the second handle 6 are sharp blades. The above is the existing structure. The principle can be referred to the multi-purpose archaeological hammer disclosed in Chinese Utility Model Patent No. CN203918966U, which will not be elaborated here.

[0019] In the aforementioned prior art, since the inner sides of the first ruler 7 and the second ruler 6 are both sharp blades, when the first and second rulers are overlapped and used as a hammer handle, the sharp blades on the inner sides of the first and second rulers can easily injure the hands of archaeologists. To solve the above problem, the main innovation of this utility model is as follows: The first ruler 7 is fixed with a hammer handle 2. The fixing method can be welding or bolt fixing, which is not limited here. The hammer handle 2 includes a grip 4. The grip 4 has a slot 1. The slot 1 passes through both ends of the hammer handle 2 and one side near the second ruler 6. The second ruler 6 can rotate into the slot 1, and the second ruler 6 is detachably connected to the slot 1. The width of the slot 1 is greater than the width of the first ruler 7 and the second ruler 6.

[0020] With the above structure, when the first handle 7 and the second handle 6 are used as hammer handles, the second handle 6 can be rotated and limited into the slot 1 provided in the hammer handle 2. Compared with the first handle 7 and the second handle 6, the hammer handle 2 is more convenient to hold and can prevent the hand from being cut by sharp blades.

[0021] For easy gripping, the outer surface of the grip 4 is fixedly covered with a rubber sleeve 3, and the side of the rubber sleeve 3 is provided with a finger grip groove.

[0022] In this embodiment, a magnet 5 is fixed inside the slot 1, and the second handle 6 is a metal iron structure, or a metal iron is fixed on the second handle 6. When the second handle 6 is stored inside the slot 1, the attraction force of the magnet 5 can easily limit the second handle 6 in the slot 1.

[0023] Example 2 Example 2 has a structure that is largely the same as Example 1, except that: Figure 3 As shown, the inner side of the second handle 6 is provided with an L-shaped slot 14, the side of the handle 4 is provided with a groove 11, an L-shaped block 10 is slidably provided in the groove 11, a spring 12 is connected to one end of the L-shaped block 10 and the groove 11, an opening 13 is provided through the groove 11 near the slot 1, and one end of the L-shaped block 10 is movably provided in the opening 13.

[0024] With the above structure, after the second ruler 6 is stored in the slot 1, the L-shaped locking block 10 can slide into the L-shaped slot 14 to limit the second ruler 6. The L-shaped locking block 10 is kept in the L-shaped slot 14 by the elastic force of the spring 12.

[0025] In summary, this utility model, while maintaining the original measuring and cutting functions of the archaeological hammer, adopts a slotted hammer handle design that can store sharp blades to avoid accidental injury, while optimizing grip comfort and limiting stability, thereby greatly improving the safety, convenience and practicality of the tool.

[0026] 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.
