[0030] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0031] like Figure 1As shown, this embodiment provides a backpack-type suspension device, including: a backpack 1, a first support rod 201 and a second support rod 202, a balancer 101 is arranged in the backpack, one end of the first support rod 201 is fixedly connected to the backpack, the other end of the first support rod 201 is movably and detachably connected to one end of the second support rod 202 through a support assembly 3, and the suspension rope in the balancer 101 extends along the first support rod 201 and the second support rod 202 to the other end of the second support rod 202. During the specific implementation of this embodiment, the setting of the backpack-type structure can effectively facilitate the use of the user. After the first support rod and the second support rod are assembled during use, the entire device can be carried on the backpack, and the second support rod extends horizontally from above the user's head to the front, and under the action of the balancer, the hanging rope can lift the power tool, which can be a new energy power tool, to achieve operation. In this process, the first support rod and the second support rod provide bearing capacity; and the second support rod in this device is movably and detachably connected to the first support rod through a support assembly, so that it can effectively realize rotation, foldability and detachability, that is, when not in use, it can be stored by folding or disassembling, which can greatly reduce the product packaging volume and facilitate transportation and storage.

[0032] like Figure 1 and Figure 2 As shown, in the above embodiment, the movable and detachable connection can be: the support assembly 3 includes a pair of splints 301 and a fixing pin 302, the first support rod 201 is vertically arranged on the backpack, a pair of splints 301 are clamped on both sides of the first support rod 201, the splints are fixedly connected to the first support rod, and the second support rod is arranged horizontally and fixedly connected to the splints 301 through the fixing pin 302. That is, in this embodiment, the movable and detachable connection between the first support rod and the second support rod is realized by the splints and the fixing pin, so as to facilitate the storage and transportation of the device; in addition, in this embodiment, the setting of the splints and the fixing pin can not only realize the movable and detachable connection between the first support rod and the second support rod, but also provide a supporting force to the second support rod, so as to increase the load-bearing capacity of the second support rod. Of course, in different embodiments, the movable and detachable connection can also be directly realized by a pin shaft or a hinge.

[0033] like Figure 2 As shown, in some embodiments, the support assembly 3 further includes an oblique brace 303, which is obliquely arranged between the clamping plates and fixedly connected to the clamping plates, and one end of the oblique brace 303 is connected to the first support rod, and the other end is connected to the second support rod. The oblique arrangement of the oblique brace can further increase the load-bearing capacity of the second support rod and prevent the second support rod from breaking or bending.

[0034] In certain embodiments, such as Figure 2 and Figure 3As shown, a first roller bearing 401 is provided above the first support rod between the clamping plates, a second roller bearing 402 is provided in one end of the second support rod close to the clamping plates, and the suspension rope of the balancer 101 passes through the first support rod 201, is wound around the first roller bearing 401 and the second roller bearing 402 in sequence, and passes through the second support rod 202 to extend out of the front end of the second support rod 202. In this embodiment, the arrangement of the first roller bearing and the second roller bearing can effectively provide a guiding effect for the suspension rope, and make the suspension rope smoother during operation, avoid rope jamming, and reduce wear.

[0035] In various embodiments, Figure 4 and Figure 5 As shown, a third roller bearing 403 is provided at the front end of the second support rod, and after the suspension rope passes through the second support rod 202, it is wound around and connected with the third roller bearing 403 and extends out of the second support rod 202. In this embodiment, the provision of the second roller bearing can prevent the front end of the suspension rope from directly contacting the second support rod, thereby avoiding rope jamming and reducing wear.

[0036] In addition, to facilitate the lifting of power tools, such as Figure 4 and Figure 5 As shown, in some embodiments, a hook 404 is provided at the front end of the suspension rope, and an anti-pinch ball 405 is provided between the hook 404 and the second support rod 202. In this embodiment, the provision of the anti-pinch ball can effectively prevent the hand from being clamped between the hook and the second support rod when the suspension rope is recovered or pulled out, thereby preventing the hand from being clamped. Since the top end surface of the anti-pinch ball is arc-shaped and the contact between the anti-pinch ball and the second support rod is point contact, the hand is not easily clamped in the middle.

[0037] like Figure 2 and Figure 4 As shown, in this embodiment, the first support rod 201 is a telescopic rod 5. The telescopic rod 5 structure can adjust the height of the whole machine according to the workers of different body shapes, so that the operator can get more room for movement in a narrow space. Specifically: the first support rod 201 includes a mother tube 501 and a child tube 502, one end of the child tube is sleeved in the mother tube and connected by a pin 503. Of course, in different embodiments, the telescopic rod 5 can also be a telescopic rod with a driving force, etc.

[0038] like Figure 6As shown, a fixing plate 102 is provided in the backpack, the bottom end of the first support rod is fixedly connected to the fixing plate 102, a wedge block 103 is provided between the fixing plate 102 and the first support rod 201, and the thickness of the wedge block 103 is gradually thinned from top to bottom. In this embodiment, the setting of the wedge block 103 and the structure of the wedge block 103 gradually thinning from top to bottom can make the first support rod tilt outward at an appropriate angle from bottom to top, so that when the user is using it, it can provide the user's head with an activity space to lean back, avoiding the collision between the user's head and the first support rod. The setting of the activity space can effectively relieve the user's head fatigue.

[0039] like Figure 7 As shown, in some embodiments, the device further includes a battery pack 104, the backpack is provided with a battery pack installation slot 105 and an external socket 106, the battery pack 104 is arranged in the battery pack installation slot 105, and the battery pack is electrically connected to the external socket 106. In this embodiment, the battery pack installation slot 105 can be a quick-release installation slot, that is, when it is necessary to provide power to the power tool, the battery pack can be installed in the battery pack installation slot, and then the power tool is provided with power through the external socket, and when it is not necessary to provide power, the battery pack can be removed, thereby effectively reducing the weight of the backpack and reducing the load on the user.

[0040] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described herein, or equivalent structural or equivalent process transformations made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the scope of patent protection of the utility model.
