[0028] To explain in detail the technical content, structural features, objectives, and effects of the technical solution, the following description is provided in conjunction with specific embodiments and accompanying drawings.

[0029] In recent years, some spring balancers have emerged, which are worn on the back by the user for suspension, thus saving effort and allowing for continuous work for extended periods. However, in actual use, the following problems have been found with existing backpack-style spring balancers:

[0030] (1) The device is large and heavy, making it unportable;

[0031] (2) The structural design is unreasonable, and the range of motion of the user is limited after wearing it;

[0032] (3) It cannot provide power output. When working at height, the power supply on the tool itself cannot provide power output for the tool for a long time.

[0033] (4) Both manual and automatic systems have safety hazards. When the rope is retracted to the top, it may pinch your hand.

[0034] Therefore, there is a need for a backpack-style suspension device that is easy to carry and operate.

[0035] As shown in Figures 1 and 2, 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 provided inside the backpack. One end of the first support rod 201 is fixedly connected to the backpack, and the other end of the first support rod 201 is connected to one end of the second support rod 202. A suspension rope inside 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. In the specific implementation of this embodiment, the backpack-type structure effectively facilitates user operation. After assembling the first and second support rods, the entire device can be carried on the backpack. The second support rod extends laterally from above the user's head to the front, and under the action of the balancer, the suspension rope can suspend a power tool, which can be a new energy power tool, to perform the operation. During this process, the first and second support rods provide load-bearing capacity. The backpack-style structure of this device effectively facilitates user operation and saves physical effort. After assembling the first and second support rods, the entire device can be carried on the backpack. With the help of the balancer, the suspension rope can suspend the power tool to perform the operation. During this process, the user does not need to use a lot of force to lift the power tool. The user only needs to control the working position and direction of the power tool. Throughout the process, the first and second support rods provide the support force for suspending the power tool, and the balancer provides the lifting force.

[0036] In addition, during actual use, it was found that the existing backpack-style spring balancer uses a single suspension rope for suspension. After suspension, it cannot guarantee that the power tool will not fall, thus compromising the safety of workers during the work process.

[0037] As shown in Figure 2, the backpack-style suspension device also includes a fall arrest mechanism, one end of which is mounted on the second support rod 202. When a user is using a power tool, if the suspension rope suddenly becomes loose or breaks, the power tool will suddenly fall, easily causing injury to the user or damage to the tool upon impact with the ground. This device, with the other end of the fall arrest mechanism connected to the power tool, effectively prevents the power tool from falling due to a sudden loosening or breakage of the suspension rope, thus significantly improving the safety of the device and allowing the user to continue working in a safe environment.

[0038] As shown in Figure 2, in this embodiment, the fall protection mechanism is a fall protection rope 104, one end of which is connected to the other end of the second support rod 202. The fall protection mechanism uses a fall protection rope, with one end connected to the other end of the second support rod and the other end connected to the handheld tool. This prevents the suspension rope from breaking, causing the handheld tool to fall, damaging the tool, and injuring personnel. Of course, in different embodiments, the fall protection mechanism can also be other structures, such as a fall protection rod or a fall protection wire rope.

[0039] In this embodiment, the fall arrest rope can be a snap-lock fall arrest rope, and a fixed beam 105 is provided at the other end of the second support rod. The snap-lock fall arrest rope is locked to the fixed beam 105 through a snap-lock.

[0040] As shown in Figures 1 and 2, the other end of the first support rod 201 is detachably connected to one end of the second support rod 202 via the support assembly 3. The suspension rope inside 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. In the specific implementation of this embodiment, the backpack-style structure effectively facilitates user operation. After assembling the first and second support rods, the entire device can be carried on the back of the backpack. The second support rod extends laterally from above the user's head to the front, and under the action of the balancer, the suspension rope can suspend the power tool, which can be a new energy power tool, to perform the operation. During this process, the first and second support rods provide load-bearing capacity. Furthermore, the second support rod in this device is detachably connected to the first support rod via the support assembly, thereby effectively achieving rotational folding and detachment. That is, when not in use, it can be stored by folding or disassembling, which greatly reduces the product packaging volume and facilitates transportation and storage.

[0041] As shown in Figures 1-3, in the above embodiments, the detachable connection can be as follows: the support assembly 3 includes a pair of clamps 301 and a fixing pin 302. The first support rod 201 is vertically mounted on the backpack, and the pair of clamps 301 are clamped on both sides of the first support rod 201, with the clamps fixedly connected to the first support rod. The second support rod is horizontally mounted and fixedly connected to the clamps 301 via the fixing pin 302. That is, in this embodiment, the detachable connection between the first and second support rods is achieved through the clamps and fixing pin, facilitating the storage and handling of the device. Furthermore, in this embodiment, the clamps and fixing pin not only enable the detachable connection between the first and second support rods but also provide support force to the second support rod, thereby increasing its load-bearing capacity. Of course, in different embodiments, the detachable connection can also be achieved directly through a pin or hinge.

[0042] As shown in Figure 3, in some embodiments, the support assembly 3 further includes a diagonal brace 303. The diagonal brace 303 is inclinedly disposed between the clamping plates and fixedly connected to the clamping plates. One end of the diagonal brace 303 is connected to the first support rod, and the other end is connected to the second support rod. The inclined arrangement of the diagonal brace can further increase the load-bearing capacity of the second support rod and prevent the second support rod from breaking or bending.

[0043] In some embodiments, as shown in Figures 3 and 4, a first roller bearing 401 is provided above the first support rod located between the clamping plates, and a second roller bearing 402 is provided inside one end of the second support rod near the clamping plates. The suspension rope of the balancer 101 passes through the first support rod 201, is sequentially wound around the first roller bearing 401 and the second roller bearing 402, and extends through the second support rod 202 beyond its front end. In this embodiment, the arrangement of the first and second roller bearings can effectively guide the suspension rope, making it smoother during operation, preventing rope jamming, and reducing wear.

[0044] In different embodiments, as shown in Figures 5 and 6, a third roller bearing 403 is provided at the front end of the second support rod. After the suspension rope passes through the second support rod 202, it is wound around and connected to the third roller bearing 403, and extends out of the second support rod 202. In this embodiment, the second roller bearing prevents the front end of the suspension rope from directly contacting the second support rod, thereby avoiding rope jamming and reducing wear.

[0045] Furthermore, to facilitate the lifting of power tools, as shown in Figures 5 and 6, 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 anti-pinch ball effectively prevents the hand from being pinched between the hook and the second support rod when the suspension rope is retracted or pulled out, thus avoiding injury. Since the top end face of the anti-pinch ball is arc-shaped and the contact between it and the second support rod is point contact, the hand is less likely to be pinched in the middle.

[0046] As shown in Figures 3 and 5, in this embodiment, the first support rod 201 is a telescopic rod 5. The telescopic rod 5 structure allows for adjustment of the overall machine height to accommodate workers of different body types, providing operators with greater operational space in confined areas. Specifically, the first support rod 201 includes a main tube 501 and a sub-tube 502, with one end of the sub-tube fitted inside the main tube and connected via a pin 503. Of course, in different embodiments, the telescopic rod 5 can also be a telescopic bar with a driving force, etc.

[0047] As shown in Figure 7, the backpack contains a fixing plate 102. The bottom end of the first support rod is fixedly connected to the fixing plate 102. A wedge 103 is located between the fixing plate 102 and the first support rod 201, and the thickness of the wedge 103 gradually decreases from top to bottom. In this embodiment, the wedge 103 and its gradually thinning structure allow the first support rod to tilt outward at a suitable angle from bottom to top. This provides the user with space to tilt their head back, preventing collision between the user's head and the first support rod. This space effectively alleviates head fatigue for the user.

[0048] As shown in Figure 8, in some embodiments, the device further includes a battery pack 106. The backpack has a battery pack mounting slot 107 and an external connector 108. The battery pack 106 is disposed in the battery pack mounting slot 107 and is electrically connected to the external connector 108. In this embodiment, the battery pack mounting slot 107 can be a quick-release mounting slot. That is, when power needs to be provided to the power tool, the battery pack can be installed in the battery pack mounting slot, and then power can be provided to the power tool through the external connector. When power is not needed, the battery pack can be removed, thereby effectively reducing the weight of the backpack and reducing the user's load.
