Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0025] like Figures 1-5 As shown, this utility model embodiment specifically provides a shock-absorbing handle equipped with a motor, including:

[0026] Cutting motor 1;

[0027] The main handle frame 2 is located on one side of the cutting motor 1, and the bottom of the side wall of the housing of the cutting motor 1 is connected to the main handle frame 2 through the shock absorbers 3 arranged on the front and rear sides; the arrangement of the shock absorbers 3 can buffer and absorb the vibration transmitted during the operation of the cutting machine, so that the vibration cannot be transmitted to the main handle frame 2.

[0028] The power supply mounting plate 4 is located above the cutting motor 1, and one end is connected to the main handle frame 2. The top of the housing of the cutting motor 1 is connected to the power supply mounting plate 4 through shock absorbers 5 arranged on the front and rear sides. The arrangement of the shock absorbers 5 can buffer and absorb the vibration transmitted during the operation of the cutting machine, so that the vibration cannot be transmitted to the power supply mounting plate 4; since the auxiliary handle frame 6 is mounted on the power supply mounting plate 4, the vibration cannot be transmitted to the auxiliary handle frame 6 either.

[0029] The main handle frame 2 is a triangular frame, which improves the structural stability of the main handle frame 2. The right side wall of the triangular frame also includes an integrally formed connecting block 1 21 and connecting block 22, which are used to connect with the shock absorber 1 3 and the power mounting plate 4, respectively.

[0030] The shock absorber 3 includes a fixing screw 31 and a shock-absorbing spring 32. The fixing screw 31 is symmetrically and movably inserted into the front and rear sides of the connecting block 21, and the ends of the fixing screw 31 are threaded and locked onto the side wall of the cutting motor 1 housing. Two shock-absorbing springs 32 are sleeved on the fixing screw 31. One shock-absorbing spring 32 has its two ends abutting against the end face of the fixing screw 31 and the connecting block 21, respectively, while the other shock-absorbing spring 32 has its two ends abutting against the connecting block 21 and the side wall of the cutting motor 1 housing. The main function of the shock absorber 3 is to reduce the transmission of vibrations generated by the cutting machine during operation to the operator's hand or the cutting motor 1 through the buffering effect of the shock-absorbing springs 32, thereby improving the stability and safety of the cutting machine and extending the service life of the cutting motor 1. The shock absorber 3 consists of the fixing screw 31 and the shock-absorbing springs 32. During operation, the vibrations generated by the cutting machine are transmitted to the shock absorber 3 through the housing of the cutting motor 1. At this time, the two ends of the damping spring 32 abut against the connecting block 21 and the side wall of the cutting motor 1 housing, respectively. When vibration occurs, the damping spring 32 will deform as if compressed or stretched, thereby absorbing and buffering the vibration energy and reducing the transmission of vibration. At the same time, the end of the fixing screw 31 is threaded and locked onto the side wall of the cutting motor 1 housing, so that the damping component 3 is tightly connected to the housing of the cutting motor 1, ensuring the stability and reliability of the damping component 3.

[0031] The bottom of the power supply mounting plate base 4 also includes a connecting block 3 41, which is used to lock and fix the connecting block 22 and the connecting block 3 41 together with a locking bolt.

[0032] The second shock absorber 5 includes: a second fixing screw 51 and a shock-absorbing rubber column 52; four fixing screws 51 are symmetrically and movably inserted into the power mounting plate 4, and the ends of the fixing screws 51 are threaded and locked onto the top of the housing of the cutting motor 1. The shock-absorbing rubber column 52 is sleeved on the fixing screws 51, and the upper and lower ends of the shock-absorbing rubber column 52 abut against the top of the housing of the power mounting plate 4 and the cutting motor 1, respectively. When the cutting motor 1 vibrates in the vertical direction, the elastic deformation of the shock-absorbing rubber column 52 can effectively reduce the vibration transmitted to the power mounting plate 4 and the auxiliary handle bracket 6, reducing the vibration intensity felt by the operator when holding the auxiliary handle bracket 6. The fixing screws 51 are used to connect the power mounting plate 4 to the top of the housing of the cutting motor 1, ensuring the stability of the entire structure, while avoiding over-tightening of the fixing screws 51, which would cause the rubber column to be over-compressed and lose its deformation space.

[0033] It also includes a secondary handle bracket 6, which is mounted on the other end of the power mounting plate base 4.

[0034] This utility model also provides a lithium battery cutting machine, including the shock-absorbing handle, connecting plate 7, transmission mechanism 8, cutter head assembly 9, and lithium battery pack 10 as described above. A cutting motor 1 is mounted on one end of the connecting plate 7, and a rotatable cutter head assembly 9 is mounted on the other end. The cutting motor 1 and the cutter head assembly 9 are connected by the transmission mechanism 8. The lithium battery pack 10 is detachably mounted on the power supply mounting plate 4. The transmission mechanism 8 includes a driving pulley, a driven pulley, and a transmission belt.

[0035] The lithium battery pack 10 is equipped with two 36V lithium battery packs 10 connected in series to provide a working power supply of 72V for the cutting machine during operation.

[0036] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
