[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 and Figure 2The utility model provides an embodiment: a portable lithium-ion light hammer, comprising a box body 1, which can accommodate a lithium-ion light hammer, a battery and a drill bit. The top of the box body 1 is hinged with an upper cover 2, and the front ends of the box body 1 and the upper cover 2 are provided with buckles, which are convenient for opening and closing, so as to conveniently store and retrieve the lithium-ion light hammer. The front end of the box body 1 is fixedly connected with a handle 3, which can facilitate operators to carry or move the entire tool box. The inner wall of the bottom end of the box body 1 is provided with an extension component, and the extension component includes a moving rod 41. The outer wall of the rear side of the moving rod 41 is slidably connected to the inner wall of the bottom end of the box body 1 and can slide in the box body 1. The inner wall of the moving rod 41 is slidably connected with a pull rod 42, and the pull rod 42 can be pulled out from the inner wall of the moving rod 41 by pulling the pull rod 42, so as to facilitate the operator to pull. The top end of the rear side of the moving rod 41 is hinged with a hinged rod 1 43, which serves as a lever in the extension component and is used to transmit and change the direction of force. At the same time, the hinged rod 1 43 is limited in the horizontal direction by the hinged position.

[0033] Reference Figure 2 and Figure 4 The box body 1 is fixedly connected with a limiting column 44 near the rear side of the moving rod 41, and a slide plate 45 is slidably connected to the outer wall of the upper side of the limiting column 44. The moving direction of the slide plate 45 is limited by the limiting column 44, and the stability of the slide plate 45 can be increased. The front end of the slide plate 45 is hinged to the rear end of the hinge rod 43, and the front end of the slide plate 45 is hinged to the rear end of the hinge rod 43, and the rear end is hinged to the connecting rod 48 to form a movable structure. The top of the slide plate 45 is elastically connected to the box body 1 through a compression spring 47. When the extension component is not extended, the initial state of the compression spring 47 is compressed. State, the elastic force of the compression spring 47 when compressed assists in driving the slide plate 45 to move down along the limiting column 44, providing assistance for unfolding the extension component. At the same time, the length setting of the compression spring 47 can prevent the hinge rod 43 and the slide plate 45 from being in the same horizontal plane, making it easier to retract the roller 49. The rear end of the slide plate 45 is hinged with a hinge rod 46, and the movement of the slide plate 45 drives the hinge rod 46 to move, thereby driving the connecting rod 48 to slide on the inner walls of the two sets of slide grooves 410, so that the roller 49 moves out of the box body 1, and the inner wall of the bottom end of the rear side of the hinge rod 46 is fixedly connected with a connecting rod 48.

[0034] Reference Figure 1 and Figure 4The right outer wall of the connecting rod 48 is rotatably connected to a roller 49, and a slide groove 410 is provided on both sides of the box body 1 near the roller 49. The right outer wall of the connecting rod 48 slides on the inner wall of the slide groove 410, and the slide groove 410 is set to be tilted downward, which can provide guidance and limitation for the movement of the connecting rod 48. There are two groups of slide grooves 410, which can increase the stability of the connecting rod 48 and the roller 49. There are two groups of pull rods 42, and two groups of extension components are set to increase the stability of the pulling device. The two groups of pull rods 42 are fixedly connected by the handle 7, and the rear outer wall of the handle 7 slides on the front inner wall of the box body 1. A groove is provided on the upper side of the handle 7 near the front end of the box body 1, which can facilitate the user to pull the handle 7. The handle 7 can facilitate the operator to pull the two groups of pull rods 42 and operate the two groups of extension components at the same time.

[0035] Reference Figure 2 and Figure 3 A limiting component is provided on the right side of the moving rod 41 of the box body 1, and the limiting component includes a limiting block 51. The limiting block 51 is set in a semicircular shape near the limiting hole and can slide on the inner wall of the limiting hole. The outer wall of the right side of the limiting block 51 is slidably connected to the inner wall of the box body 1. The limiting block 51 is elastically connected to the box body 1 through a return spring 52. The elastic force of the return spring 52 causes one side of the limiting block 51 to slide out of the inner wall of the box body 1 and contact the limiting hole, thereby limiting the moving rod 41. A limiting hole is provided on the right side of the moving rod 41 near the limiting block 51. There are multiple groups of limiting holes, which are respectively arranged at the bottom end and the right side of the moving rod 41. The left side of the limiting block 51 slides on the inner wall of the limiting hole. There are multiple groups of limiting components, and another group of limiting components are respectively arranged on the inner wall of the rear side of the pull rod 42, which can limit the pull rod 42 and improve the stability of the pull rod 42 after extension.

[0036] Reference Figure 1 and Figure 5 A protective component is provided at the bottom of the upper cover 2, and the protective component includes a stabilizing plate 61. The top of the stabilizing plate 61 is fixedly connected to the inner wall of the bottom end of the upper cover 2. The stabilizing plate 61 is provided with slots for batteries and drill bits corresponding to the box body 1. A cover plate 62 is slidably connected to the inner wall on the left side of the stabilizing plate 61. The cover plate 62 is provided with a slot that matches the lithium-ion light hammer. At the same time, a buffer sponge is provided inside the slot to reduce shaking and collision that may occur during movement or carrying. The top of the cover plate 62 is elastically connected to the upper cover 2 by a compression spring 63 to ensure that the lithium-ion light hammer is properly placed in the slot and protected by the buffer sponge.

[0037] Working principle: During use, when the toolbox is heavy and it is difficult to pick up the toolbox by the handle 3, the handle 7 can be pulled to drive the pull rod 42 to slide on the inner wall of the moving rod 41, thereby sliding out from the inner wall of the moving rod 41, and then driving the limit block 51 to slide into the inner wall of the limiting hole, thereby limiting the pull rod 42, and then pulling the pull rod 42 to drive the moving rod 41 to slide on the inner wall of the box body 1, thereby driving the hinged rod 1 43 to move, and the slide plate 45 is moved downward on the limiting column 44 through the hinge. At the same time, the elastic force of the compression spring 1 47 assists in driving the slide plate 45 to move downward, driving the hinged rod 2 46 to move.

[0038] The hinged rod 46 drives the connecting rod 48 to slide on the inner wall of the slide groove 410, thereby driving the roller 49 to move, so that the roller 49 moves out of the inner wall of the box body 1. At this time, the inner wall of the limiting hole on the outer wall of the pull rod 42 slides into another set of limit blocks 51, and the movable rod 41 is limited by the elastic force of the reset spring 52, thereby limiting the roller 49 to prevent the roller 49 from sliding into the inner wall of the box body 1. At this time, the operator can pull the device through the handle 7 to move it through the roller 49, thereby increasing the portability of the device.

[0039] During the transportation of the device, the lithium-ion light hammer inside the box 1 will vibrate with the box 1. At this time, the elastic force of the compression spring 2 63 in the compressed state drives the cover plate 62 to stabilize the lithium-ion light hammer, which can absorb and disperse the vibration and impact generated during transportation. The drill bit and battery of the lithium-ion light hammer are limited and protected by the stabilizing plate 61.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
