Through the arrangement of the two guide shafts 5, the bracket 3 can slide up and down along the two guide shafts 5, and the limit round block 511 can prevent the two guide shafts 5 from disengaging from their corresponding linear bearings 311. In order to prevent the two limit round blocks 511 from colliding with their corresponding linear bearings 311, a buffer ring 512 is provided at the lower end of each guide shaft 5 to play a buffering role. In order to prevent the limit round blocks 511 at the bottoms of the two guide shafts 5 from colliding with the inner bottom wall of the bracket 3, limit blocks 314 are provided on both the left and right sides of the inner bottom wall of the bracket 3. A relief groove is provided at the top of each limit block 314. The two limit round blocks 511 respectively correspond to the relief grooves of the two limit blocks 314 in position. When the bracket 3 rises, the limit round block 511 at the bottom of each guide shaft 5 first impacts in the relief groove for buffering. Among them, the limit block 314 is made of elastic rubber material.

[0029] The buffer mechanism 2 is used in cooperation with two guide shafts 5 to buffer the upward displacement of the bracket 3. The buffer mechanism 2 includes two guide rods 312.

The top of each guide rod 312 is fixedly connected to the bottom of the connecting plate 1. The two guide rods 312 are both located between the two guide shafts 5. A second spring 313 is sleeved on each guide rod 312. Each second spring 313 is located between the connecting plate 1 and the top of the bracket 3.

[0032] The gripper body 712 is a square block, and the gripper 713 is fixedly located at the lower end of the left side of the gripper body 712;

[0033] The longitudinal vertical section of the sliding plate 711 is in the shape of a "gong" character. The sliding plate 711 is slidably inserted into the chute. Limiting strips 716 are fixedly arranged at the lower ends of the front side and the rear side of the sliding plate 711. A first chute with a vertical section in the shape of a "tu" character is formed at the top of the gripper body 712. The gripper body 712 is slidably inserted onto the two limiting strips 716 through the first chute;

[0034] A transverse second rack 717 is formed at the middle position of the bottom of the sliding plate 711;

A baffle 720 is fixedly provided at the front side of the gripper body 712. The baffle 720 is fixedly connected to the gripper body 712 by screwing with the second screws. A third circular through-hole corresponding to the position of the second circular through-hole is provided at the front side of the baffle 720;

[0038] The rocker arm 715 is a round shaft. A cam 721 is fixedly provided at the middle position of the rocker arm 715. The cam 721 is in an elliptical shape. The rocker arm 715 is inserted into the third square through-hole of the gripper body 712. The rear side of the rocker arm 715 is inserted into the second circular through-hole. The cam 721 of the rocker arm 715 is located within the second square through-hole of the first rack 714. The front side of the rocker arm 715 is inserted into the third circular through-hole. When the cam 721 is horizontally placed, the cam 721 abuts against the inner bottom wall of the second square through-hole of the first rack 714. At this time, the upper end of the first rack 714 protrudes from the top of the gripper body 712;

[0039] During installation, first insert the first rack 714 into the square groove. Subsequently, place the first springs 718 in the two first placement grooves of the first rack 714. Then fix the cover plate 719. The cover plate 719 abuts against the two first springs 718. The two first springs 718 rebound and push the upper end of the first rack 714 out of the top of the gripper body 712. Insert the rocker arm 715 through the third square through-hole of the gripper body 712 into the second square through-hole of the first rack 714. Subsequently, the rear side of the rocker arm 715 is inserted into the second circular through-hole. Then fix it with a first-hole retaining ring. At this time, insert the baffle 720 through the third circular through-hole into the front side of the rocker arm 715, and fix the front side of the rocker arm 715 with a second-hole retaining ring at the front side of the baffle 720. Fix the baffle 720 with two screws to complete the assembly of the jaw assembly 7.

[0040] On the front and rear sides of the bottom right of the jaw assembly 7 located on the left, there are fourth circular perforations. A ball plunger 722 is fixedly provided in each fourth circular perforation. A number of hemispherical pits are arrayed on the front and rear sides of the bottom of the sliding plate 711. Through the arrangement of the ball plunger 722 and the hemispherical pits, a positioning effect can be achieved.

[0041] Specific implementation process:

[0042] Step 1: Adjust the distance between the two grippers 713;

[0043] First, rotate the rocker arm 715. Since the cam 721 of the rocker arm 715 rotates, it pushes the first rack 714 downward, and the two first springs 718 are compressed. Since the first rack 714 and the second rack 717 do not mesh with each other, at this time, the gripper body 712 can slide on the sliding plate 711;

[0044] Step 2: Position through the ball plunger 722 and the hemispherical pits at the bottom of the sliding plate 711;

[0045] Step 3: After positioning is completed, rotate the rocker arm 715. At this time, the cam 721 of the rocker arm 715 is horizontally placed. The first rack 714 rises under the elastic force of the two first springs 718, and the first rack 714 meshes with the second rack 717, then the fixation of the gripper body 712 can be completed;

[0046] Step 4: When grasping the battery, the device pushes the connecting plate 1, and the connecting plate 1 drives the bracket 3 to move towards the battery. When the two grippers 713 grasp the battery, since it moves downward, its jaw assembly 7 contacts the place where the battery is placed, generating an impact and forming a reaction force. At this time, the bracket 3 moves upward along the two guide shafts 5, and the two second springs 313 are compressed;

[0047] Step 5: The pneumatic parallel gripper 6 works, driving the two sliding plates 711 to move towards the battery, and the two grippers 713 clamp the battery;

[0048] Step 6: After the battery is grasped, first, the device pulls the connecting plate 1, and the second spring 313 rebounds. When the buffer ring 512 at the top of the limit circular block 511 of each guide shaft 5 abuts against the bottom of its corresponding linear bearing 311, the connecting plate 1 drives the battery on the jaw assembly 7 to displace through the bracket 3.

[0049] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
