Description

Technical Field

[0001] This utility model relates to the field of power tool technology, and more specifically, to an electric palm hammer. Background Technology

[0002] A hammer is a tool used to strike objects, causing them to move or deform. It is most commonly used to drive nails, straighten things, or break objects apart. Current manual hammers generally consist of a handle and a hammer body, requiring manual force to strike, which is relatively strenuous.

[0003] Publication number CN221953248U discloses a shock-absorbing hand hammer for door and window installation, including a hammer handle. A hammer body is fixedly connected to the end of the handle, and a force-relieving component is provided inside the hammer body. The force-relieving component includes a cylindrical cavity opened at one end of the hammer body, a sliding rod fixedly connected to the inner wall of the cylindrical cavity, and multiple buffer plates evenly arranged in the gap between the sliding rod and the cylindrical cavity. A hammer head is threaded onto the surface of the hammer body near the opening of the cylindrical cavity. Although this technical solution can achieve the operation of hammering nails, it is still relatively laborious. In addition, due to the long hammer handle, it is inconvenient to use in places with limited turning space. Therefore, an electric hand hammer is provided to solve the above problems.

The housing assembly 11 is a hollow cavity with dimensions matching the size of a palm, thus facilitating hand gripping. The circuit board 12 and the drive transmission assembly 13 are respectively disposed in the housing assembly 11, and the circuit board 12 is electrically connected to the drive transmission assembly 13, the battery assembly 15, and the button assembly 16. The striking assembly 14 is disposed through the housing assembly 11 and is drive-connected to the drive transmission assembly 13, which drives the striking assembly 14 to perform a striking operation. The battery assembly 15 is detachably disposed on the housing assembly 11, providing power to the circuit board 12 and the drive transmission assembly 13. The button assembly 16 is disposed through the housing assembly 11 and controls the working status of the drive transmission assembly 13.

[0029] Please see Figure 1 and Figure 2 As shown, in this embodiment, the housing assembly 11 is provided with a connecting hole 111 and a button hole 112, respectively. The striking assembly 14 and the button assembly 16 pass through the housing assembly 11 through the connecting hole 111 and the button hole 112, respectively. The housing assembly 11 is provided with a plurality of heat dissipation holes 113, the positions of which correspond to the positions of the drive transmission assembly 13, so as to facilitate the heat dissipation operation of the drive transmission assembly 13. Anti-slip parts 114 are provided on the housing assembly 11 at the positions corresponding to the palm and fingers gripping, thereby increasing the friction between the palm and fingers and the housing assembly 11, so as to facilitate the user to firmly grip the electric palm hammer 10. Specifically, the anti-slip parts 114 can be stripes or raised dots. In this embodiment, the anti-slip parts 114 are horizontal raised stripes.

[0030] Please see Figure 2 As shown, in this embodiment, the circuit board 12 is electrically connected to the drive transmission assembly 13, the battery assembly 15, and the button assembly 16, respectively.

In this embodiment, the transmission mechanism 134 includes a rotating shaft 1341, a large bevel gear 1342, and an impact member 1343. The rotating shaft 1341 is rotatably mounted in the housing assembly 11 via bearings. The large bevel gear 1342 is rotatably mounted on the rotating shaft 1341 and is connected to the small bevel gear 133, forming a second-stage reduction structure. The impact member 1343 is rotatably mounted on the rotating shaft 1341 and is fixedly connected to the large bevel gear 1342. It rotates with the large bevel gear 1342. The impact member 1343 can intermittently contact and connect with the striking assembly 14, thereby performing a striking operation on the nails in the striking assembly 14. Specifically, at least one impact protrusion 13431 is fixedly provided on the side of the impact member 1343, and the impact protrusion 13431 is used to intermittently strike the striking component 14. In this embodiment, two impact protrusions 13431 are integrally formed and fixedly provided on the side of the impact member 1343. In other embodiments, the number of impact protrusions 13431 can be one, three or other multiples, and the number can be set according to actual needs.

The guide cylinder 142 is detachably connected to the lower part of the fixed housing 141, and the nail can be detachably placed in the guide cylinder 142. The guide cylinder 142 can be replaced according to the different nail models. The striking rod 143 moves through the fixed housing 141 and can extend into the guide cylinder 142, and can intermittently contact and drive with the impact member 1343. The elastic element 144 is disposed between the inner wall of the fixed housing 141 and the striking rod 143, and provides a restoring force to the striking rod 143. Specifically, a through hole 1421 is provided through the guide cylinder 142, and one end of the striking rod 143 extends movably into the through hole 1421; a magnetic attractor 1422 is fixedly provided on the inner wall of the through hole 1421, and the iron nail provided in the through hole 1421 is attracted by the magnetic attractor 1422, thereby facilitating the striking operation of the iron nail; the elastic element 144 is a spring.

[0034] Please see Figure 1 and Figure 2 As shown, in this embodiment, the battery assembly 15 uses a polymer lithium-ion battery; the button assembly 16 includes a button body 161 and a button housing 162. The button body 161 is disposed in the housing assembly 11 and electrically connected to the circuit board 12; the button housing 162 is disposed on the button body 161 and passes through the housing assembly 11 through the button hole 112.

[0035] It should be noted that the specific working process of the electric palm hammer 10 of this utility model is as follows: First, place the nail into the guide cylinder 142, then grip the housing assembly 11 tightly, control the drive mechanism 131 to rotate through the button assembly 16, and then drive the impact member 1343 to strike the striking rod 143 through the deceleration transmission mechanism 132, the small bevel gear 133, and the large bevel gear disk 1342 in sequence. The striking rod 143 then drives the nail in the guide cylinder 142 into the object to be fixed, thereby completing the automatic nailing operation.
