Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: Reference Figures 1 to 6A large-opening lithium battery scissors capable of bilateral linkage is shown, including an electric grip 1. Among them, the electric grip 1 is the main power component of the existing lithium battery scissors and is an existing mature well-known technology. Therefore, in this application, it will not be elaborated too much. Inside the upper end of the electric grip 1, there is a clamping piece 2. Inside the front end of the clamping piece 2, there is a bilateral cutter head 3. The bilateral cutter head 3 is composed of two inner arc-shaped blades on the left and right. And the left inner arc-shaped blade is serrated towards the inner arc end. Perforations are symmetrically opened at the rear ends of the two inner arc-shaped blades on the left and right. Among them, the outer perforation is penetrated by the second buckle 704 to connect the bilateral cutter head 3 with the first arc rod 701 and the second arc rod 702 together. And the inner perforation is penetrated by the main pin 8, so that the rear ends of the two inner arc-shaped blades on the left and right are staggered and overlapped to form a cutting structure. In the middle of the rear end of the clamping piece 2, there is a sleeve 4. The front end of the sleeve 4 extends to the inside of the rear end of the clamping piece 2. And the two groups are directly reinforced by the auxiliary pin 9. Inside the rear end of the sleeve 4, there is a connecting rod shaft 5. The front end of the connecting rod shaft 5 extends to the inside of the rear end of the connecting piece 7. And a rectangular hole is opened in the inside of the rear end of the connecting rod shaft 5 to facilitate the insertion of the transmission end of the driving motor inside the electric grip 1 for power transmission work. At the rear side of the outer end of the connecting rod shaft 5, there is a spring 6. The spring 6 is sleeved and installed in the tail area of the connecting rod shaft 5. And the front end of the spring 6 abuts against the rear end of the sleeve 4. At the front end of the connecting rod shaft 5, there is a connecting piece 7. At the front side of the upper end of the clamping piece 2, there is a main pin 8. The main pin 8 penetrates downward through the inside of the clamping piece 2 and the bilateral cutter head 3 and extends below the clamping piece 2 and is reinforced by a nut. At the rear side of the upper end of the clamping piece 2, there is an auxiliary pin 9. The auxiliary pin 9 penetrates through the rear end of the clamping piece 2 and the front end structure of the sleeve 4 from both left and right sides and extends below the clamping piece 2 and is reinforced by a nut.

[0026] As an optional implementation manner in this embodiment, as Figure 3 , Figure 4 and Figure 5 shown, the clamping piece 2 includes a first clamping plate 201, a second clamping plate 202, a front jack 203 and a rear jack 204. Below the first clamping plate 201, there is a second clamping plate 202. The first clamping plate 201 and the second clamping plate 202 are exactly the same in size and shape. In the middle of the front side of the upper ends of the first clamping plate 201 and the second clamping plate 202, there are front jacks 203 opened. At the rear sides of the upper ends of the first clamping plate 201 and the second clamping plate 202, there are rear jacks 204 opened. The rear jacks 204 are symmetrically distributed left and right.

[0027] Through the provided first clamping plate 201 and second clamping plate 202, they form an upper and lower clamping structure, which can clamp and install the sleeve 4 and the double-sided cutter head 3 inside. Then, through the provided front jack 203 and rear jack 204, in cooperation with the main pin 8 and auxiliary pin 9, the clamped sleeve 4 and double-sided cutter head 3 are limited to ensure the stability of the installation structure of the two. Subsequently, when the double-sided cutter head 3 is damaged and needs to be replaced, only the main pin 8 and auxiliary pin 9 need to be removed, and then the double-sided cutter head 3 can be taken out for replacement, which is more convenient.

[0028] As Figures 3 to 6 shown, in this embodiment, the sleeve 4 includes a cylinder body 401, an internal thread 402, a movable part 403, and a fixing hole 404. The inside of the cylinder body 401 is a hollow structure, and moreover, the diameter of the hollow structure is adapted to the outer diameter of the rod body 501. The inner side of the cylinder body 401 is provided with an internal thread 402, and the internal thread 402 is threadedly connected with the external thread 504. The front end of the cylinder body 401 is embedded with a movable part 403. There are two symmetrically distributed movable parts 403. The middle of the upper end of the movable part 403 is provided with a fixing hole 404, and the inner diameter of the fixing hole 404 is adapted to the outer diameter of the auxiliary pin 9; the connecting rod shaft 5 includes a rod body 501, a limiting piece 502, an embedding block 503, and an external thread 504. The rear end of the rod body 501 is provided with a limiting piece 502, the front end of the rod body 501 is provided with an embedding block 503, and the width diameter of the embedding block 503 is adapted to the width diameter of the rod body 501. Moreover, the rod body 501, the limiting piece 502, and the embedding block 503 are of an integral structure. The external thread 504 is provided on the right side of the outer end of the rod body 501; the connecting piece 7 includes a first arc rod 701, a second arc rod 702, a first buckle 703, and a second buckle 704. The second arc rod 702 is provided below the first arc rod 701. The contact end of the first arc rod 701 and the second arc rod 702 is provided with a first buckle 703, and the second buckles 704 are provided on the inner sides of the front ends of the first arc rod 701 and the second arc rod 702.

[0029] Through the provided embedding block 503, it can extend to the inner sides of the first arc rod 701 and the second arc rod 702. Then, the three are combined and connected together using the first buckle 703. At the same time, through the threaded connection of the internal thread 402 and the external thread 504, driven by the driving motor inside the electric grip 1, the rod body 501 can perform a relatively long reciprocating motion inside the cylinder body 401. Compared with the traditional motor with a gear drive, through the cooperation between the connecting rod shaft 5 and the sleeve 4, the double-sided cutter head 3 can have a larger mechanical movement distance, increasing the opening size to meet different usage scenarios.

[0030] Through the provided first buckle 703, the rear ends of the first arc rod 701 and the second arc rod 702 can be penetrated and connected together, enabling the first arc rod 701 and the second arc rod 702 to form an upper and lower staggered V-shaped structure. Moreover, for the front-end structures of the first arc rod 701 and the second arc rod 702, through the provided second buckle 704 penetrating the outer perforations at the rear end of the double-sided cutter head 3, the first arc rod 701, the second arc rod 702 and the double-sided cutter head 3 are connected together, facilitating subsequent linkage work.

[0031] The working principle of this utility model: This large-opening lithium battery scissors that can perform bilateral linkage, through the provided double-sided cutter head 3, compared with the traditional double-edge design, has a serrated design on the cutting edge of one side of the double-sided cutter head 3. When in use, it can be stuck on the material to prevent slippage caused by the overly smooth cutting target during use. At the same time, in addition to fixing the cutting target, for some small-sized objects, they can be directly sawed open with the serrations; secondly, through the threaded connection between the internal thread 402 and the external thread 504, the rod body 501 can reciprocate inside the cylinder body 401. Compared with the traditional motor with gear drive, through the cooperation between the connecting rod shaft 5 and the sleeve 4, the double-sided cutter head 3 can have a larger mechanical movement distance, increasing the opening size to meet different usage scenarios. Through the provided spring 6, when the circuit suddenly breaks during the reciprocating movement of the rod body 501 inside the cylinder body 401, a force is provided at the rear ends of the rod body 501 and the cylinder body 401, enabling the double-sided cutter head 3 to still maintain an open state, preventing the sudden closure of the double-sided cutter head 3 during power-off and causing dangerous situations, and improving the safety of use.
