[0048] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.
[0049] In this application, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0050] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0051] Example:
[0052] like Figure 1 to Figure 3 As shown, an embodiment of the present application discloses a multifunctional claw hammer, which can be replaced with different fits up and down, thereby improving work efficiency and expanding new functions to cope with basic household working conditions. The specific structure includes: a hammer head 1, a hammer handle 2, a plurality of ratchet accessories 3 and a plurality of functional accessories 4.
[0053] The hammer head 1 comprises a hammer body 11 and a striking part 13 . The striking part 13 is arranged at one end of the hammer body 11 and is used for striking a nail body. The hammer body 11 is connected to the striking part 13 by welding or integral molding.
[0054] The head end of the hammer handle 2 is connected to the bottom of the hammer body 11, and can be connected to the hammer body 11 by welding, riveting, bolting or integral molding; wherein the head end and the tail end of the hammer handle 2 are respectively the two ends in its length direction.
[0055] The ratchet accessory 3 includes: a driving body 31, a ratchet mechanism (not shown in the figure), an adapter 32 and a first plug rod 33; wherein the ratchet mechanism is installed in the driving body 31; one end of the adapter 32 is rotatably installed in the driving body 31 and is transmission-connected to the ratchet mechanism; the first plug rod 33 is arranged at one end of the driving body 31 away from the adapter 32.
[0056] It should be noted that the ratchet mechanism, through the cooperation between the ratchet and the pawl, allows the adapter 32 to transmit power in only one direction during the process of applying force, while it can slide freely in the opposite direction. Therefore, there is no need to readjust the pulling angle after each twisting, thereby improving the tightening and loosening efficiency. It belongs to the prior art, so its specific structure will not be described in detail.
[0057] The functional accessory 4 includes: a functional portion 41 and a second insertion rod 42 ; wherein the second insertion rod 42 is disposed at one end of the functional portion 41 .
[0058] The striking portion 13 has an end away from the hammer body 11 and is provided with a first directional insertion hole 131 and / or the tail end of the hammer handle 2 has a second directional insertion hole 21 .
[0059] It can be understood that it includes three schemes, namely: 1. A first directional hole 131 is opened on the striking part 13; 2. A second directional hole 21 is opened at the tail end of the hammer handle 2; 3. A first directional hole 131 is opened on the striking part 13 and a second directional hole 21 is opened at the tail end of the hammer handle 2.
[0060] The other end of the adapter 32 is provided with a third directional socket 321 ; the first plug rod 33 is adapted to the first directional socket 131 and the second directional socket 21 ; the second plug rod 42 is adapted to the first directional socket 131 , the second directional socket 21 and the third directional socket 321 .
[0061] It should be noted that the first directional socket 131, the second directional socket 21 and the third directional socket 321 are holes with specific shapes, such as: polygonal, elliptical, with asymmetric cuts, or with special contours, etc. These shapes match the shapes of the first plug rod 33 and the second plug rod 42, thereby ensuring that the first plug rod 33 and the second plug rod 42 can only move in the axial direction after insertion, and cannot rotate freely in the circumferential direction.
[0062] When in use, different functional accessories 4 can be replaced at the striking part 13 of the hammer head 1 and / or the tail end of the hammer handle 2 by plugging and unplugging the second plug rod 42 and the first directional socket 131 and / or the second directional socket 21, so that striking or tightening work can be performed.
[0063] In addition, the first plug rod 33 can be plugged and unplugged with the first directional socket 131 and / or the second directional socket 21, so that the ratchet accessory 3 can be installed on the striking part 13 of the hammer head 1 and / or the tail end of the hammer handle 2, and then the second plug rod 42 and the third directional socket 321 can be plugged and unplugged, and different functional accessories 4 can be replaced on the ratchet accessory 3. In this way, the unidirectional rotation characteristic of the ratchet accessory 3 is utilized to avoid the need to readjust the pulling angle after each twisting, thereby improving the tightening efficiency and reducing the labor intensity.
[0064] It is understandable that, when performing the knocking operation, since no twisting operation is required, such as Figure 4 As shown, the ratchet accessory 3 may not be installed; however, when tightening, a twisting operation is required, such as Figure 5 As shown, the ratchet accessory 3 can be optionally installed.
[0065] Through the above arrangement, the function of the claw hammer is expanded, so that when performing tightening work, only the corresponding functional accessories 4 need to be replaced, and there is no need to use a screwdriver or socket separately. It is simple to operate and easy to use, and reduces the load on the operator, avoiding physical fatigue and pain, thereby improving work efficiency and job satisfaction. By adding a ratchet accessory 3, it is avoided that the pull angle needs to be readjusted after each twisting, thereby improving the tightening efficiency and reducing the labor intensity.
[0066] In some embodiments, the functional part 41 is a hammer head, a screwdriver head or a socket; it is used for knocking, tightening or other types of work; wherein the hammer head, screwdriver head or socket has a variety of types and sizes to adapt to use under different working conditions.
[0067] Exemplarily, the hammer head is preferably cylindrical, but may also be other shapes, and is used to directly contact the object to be struck. Its striking surface may be a flat surface or a curved surface, without specific limitation.
[0068] Exemplarily, the screwdriver head can be a slotted head, a cross head, a Pozidriv head, a star head, a square head, a hexagonal head, a Y-shaped head, etc., and each type has a variety of sizes.
[0069] In some embodiments, the cross-sections of the first directional socket 131, the second directional socket 21 and the third directional socket 321 are all regular hexagons, which have good regularity, are easy to plug and unplug, are evenly stressed, have high structural strength and strong bearing capacity.
[0070] It should be noted that if Figure 1 As shown, when the functional part 41 is a hammer head, since it is only used for striking, the second plug rod 42 can also be a round rod inscribed in the first directional socket 131 and the second directional socket 21, which is not restricted from circumferential rotation, thereby improving the plugging and unplugging efficiency and facilitating use.
[0071] In some embodiments, a hollow groove 111 is formed on the hammer body 11 , and the hollow groove 111 is connected to the first directional socket 131 , which facilitates cleaning of the first directional socket 131 and avoids debris residue.
[0072] The hollow groove 111 is provided to reduce the weight while ensuring the structural strength, making it easier for operators to hold and use, thereby improving portability. In addition, the hollow groove 111 can also be used as a hanging ring, so that the claw hammer can be hung on a wall or a display board, etc., which is convenient for placement and easy for operators to take and put.
[0073] In some embodiments, it also includes: a safety rope 5, which is tied to the hammer body 11 through the hollow groove 111 and can be connected to the belt on the wrist or pants to prevent the claw hammer from falling out of the hand.
[0074] In some embodiments, Figure 3 As shown, the hammer handle 2 is of cylindrical structure and is coaxially arranged with the second directional socket 21, ensuring that after the ratchet accessory 3 or the functional accessory 4 is installed, the adapter 32 or the functional part 41 can be coaxially arranged with the hammer handle 2, thereby facilitating the rotation and tightening operation and improving the use effect.
[0075] Preferably, the adapter 32, the first inserting rod 33 and the third directional inserting hole 321 are coaxially arranged, which facilitates the rotation and tightening operation and improves the use effect.
[0076] Based on the above embodiment, the tail end of the hammer handle 2 is flat and perpendicular to the axis of the hammer handle 2, which ensures that it can fully contact with the driving body 31 or the functional part 41, thereby expanding the contact area, improving the connection stability, reducing stress concentration, and improving the bearing capacity.
[0077] Based on the above embodiments, Figure 3 As shown, the axis of the striking portion 13 is perpendicular to the axis of the hammer handle 2 , and one end of the striking portion 13 away from the hammer body 11 is a plane and parallel to the axis of the hammer handle 2 .
[0078] Through the above arrangement, the stress concentration at the connection of the first plug rod 33 or the connection of the second plug rod 42 during use is reduced, thereby avoiding breakage, improving the bearing capacity, and ensuring the use effect.
[0079] In this embodiment, the axis of the striking portion 13 is parallel to the axis of the first directional insertion hole 131 , which facilitates the disassembly and assembly of the ratchet accessory 3 or the functional accessory 4 and improves the structural strength.
[0080] In this embodiment, if Figure 2 As shown, the hammer head 1 also includes: a nail removing portion 12, which is arranged at the other end of the hammer body portion 11 and can be connected by welding or integral molding; the nail removing portion 12 is used for nail removing operation, has an arc-shaped structure, and gradually bends downward in the direction away from the hammer body portion 11, and a V-shaped groove 121 is opened on the side away from the hammer body portion 11.
[0081] Through the above arrangement, it can be adapted to nail bodies of different sizes, and the principle of lever can be used to conveniently and labor-savingly pull out the nail body, which saves time and labor and has a good use effect.
[0082] In this embodiment, if Figure 1 As shown, the cross section of the striking portion 13 is an arc with an arc length greater than a semicircle; the top of the hammer head 1 is a plane and is perpendicular to the axis of the hammer handle 2.
[0083] Through the above arrangement, the contact area between the hammer head 1 and the supporting surface is increased when removing nails, thereby reducing stress concentration, increasing the maximum force that can be applied, and further improving the nail removing effect.
[0084] Preferably, the hammer body 11 , the nail-removing portion 12 and the striking portion 13 are integrally formed, thereby improving the structural strength and stability.
[0085] In the specification of the present utility model, a lot of specific details are described. However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.
