[0032] When the clamping tool 10 is used, the sliding block 200 and the matching part 110 in the clamping tool 10 are placed between the two metal sheet supports 500 of adjacent modules, and then the driving assembly 300 is started, the driving assembly 300 drives the sliding block 200 to move towards the matching part 110, and the sliding block 200 and the matching part 110 jointly clamp the two metal sheet supports 500, thereby reducing the gap between the metal sheet supports 500 of the modules.
[0033] In the embodiments, the driving assembly 300 includes a motor 310 and a screw rod 320, the screw rod 320 is rotatably connected with the tool body 100, one end of the screw rod 320 is connected with the sliding block 200, and the motor 310 and the screw rod 320 are in transmission connection to drive the screw rod 320 to move along the length direction of the screw rod 320.
[0034] When the motor 310 drives the screw rod 320 to rotate, the motor 310 drives the screw rod 320 to move along the length direction of the screw rod 320, and the screw rod 320 drives the sliding block 200 to slide on the tool body 100 in the moving process, thereby causing the sliding block 200 to move towards or away from the matching part 110.
[0035] The motor 310 is arranged on the top of the tool body 100, and the motor 310 is provided with an opening button and a tightening button, when the opening button is pressed, the motor 310 drives the sliding block 200 to move away from the matching part 110, and when the tightening button is pressed, the motor 310 drives the sliding block 200 to move towards the matching part 110.

[0037] When the clamping tool 10 is used, the motor 310 is started, the motor 310 drives the first belt pulley 330 to rotate, the first belt pulley 330 drives the second belt pulley 340 to rotate through the belt 350, the second belt pulley 340 drives the screw rod 320 to move along the length direction of the screw rod 320, and the screw rod 320 can drive the sliding block 200 to slide on the tool main body 100 in the moving process.
[0038] In the embodiment, the tool main body 100 is provided with a containing groove 120 for containing the second belt pulley 340, the tool main body 100 is provided with a giving-up groove 130 which is communicated with the containing groove 120, and the belt 350 is partially located in the giving-up groove 130.
[0039] The first belt pulley 330 is coaxially connected with the motor 310 and located above the tool main body 100, the second belt pulley 340 is contained in the containing groove 120, and the belt 350 extends into the containing groove 120 and is matched with the second belt pulley 340 after passing through the giving-up groove 130.
[0040] In the embodiment, the screw rod 320 extends to the outside of the tool main body 100 at the end away from the sliding block 200, and the screw rod 320 is provided with a limiting part 321 at the end extending to the outside of the tool main body 100.
[0041] In the moving process of the screw rod 320 along the length direction thereof, the limiting part 321 can abut against the outer side wall of the tool main body 100, so as to limit the stroke of the screw rod 320.
[0042] In an optional embodiment, the screw rod 320 and the limiting part 321 are integrally formed to form a bolt structure, and the bolt structure can also limit the stroke of the screw rod 320.
[0043] In the embodiment, the screw rod 320 is provided with a first clamping spring 322, the sliding block 200 is provided with a connecting groove 210 and a first through hole 220 which are communicated with each other, the first clamping spring 322 is arranged in the connecting groove 210, and one end of the screw rod 320 passes through the first through hole 220 and abuts against the inner wall of the connecting groove 210.
[0044] The opening direction of the connecting groove 210 is perpendicular to the opening direction of the first through hole 220. Since the first clamping spring 322 on the screw rod 320 is arranged in the connecting groove 210, and one end of the screw rod 320 abuts against the inner wall of the connecting groove 210, the screw rod 320 can drive the sliding block 200 to slide during the movement of the screw rod 320 along the length direction of the screw rod 320.
[0045] In the embodiment, the surface of the sliding block 200 and the surface of the matching part 110 facing each other are both provided with the positioning pin 400.
[0046] It should be noted that the sheet metal support 500 of each module is provided with the positioning hole. When the clamping tool 10 is used, the sliding block 200 and the matching part 110 in the clamping tool 10 are placed between the two sheet metal supports 500 of adjacent modules, and the positioning pins 400 on the sliding block 200 and the matching part 110 are respectively inserted into the positioning holes in the two adjacent sheet metal supports 500. Therefore, the clamping process of the two sheet metal supports 500 can be smoothly carried out.
[0047] In the embodiment, the tool main body 100 is provided with the second through hole 140 and the third through hole 150 which are in communication. The opening direction of the second through hole 140 is perpendicular to the opening direction of the third through hole 150. The extension direction of the third through hole 150 is consistent with the movement direction of the sliding block 200. The sliding block 200 is provided with the connecting column 230.

The connecting column 230 penetrates the third through hole 150 from bottom to top and extends into the second through hole 140. The third through hole 150 is a waist-shaped hole. The width of the third through hole 150 is equal to the diameter of the end face of the connecting column 230.
[0049] During the movement of the sliding block 200 driven by the screw rod 320, the connecting column 230 can always move along the extension direction of the third through hole 150, thereby limiting the movement direction of the sliding block 200.
[0050] In the embodiment, the portions of the connecting column 230 located on both sides of the third through hole 150 are both provided with the second clamping spring 231. The diameter of the second clamping spring 231 is greater than the maximum width of the third through hole 150.
[0051] It should be noted that, in the case that the third through hole 150 is a waist-shaped hole, the width of the third through hole 150 at any position is consistent.
[0052] By arranging the second clamping spring 231 on the portions of the connecting column 230 located on both sides of the third through hole 150, the two second clamping springs 231 can limit the connecting column 230, so as to prevent the displacement of the connecting column 230 and the sliding block 200 along the axial direction of the connecting column 230.
[0053] In summary, the embodiment of the present application provides a clamping tool 10. When the clamping tool 10 is used, the motor 310 is started, the motor 310 drives the first pulley 330 to rotate, the first pulley 330 drives the second pulley 340 to rotate through the belt 350, the second pulley 340 drives the screw 320 to move along the length direction of the screw 320, the screw 320 can drive the sliding block 200 to slide on the tool body 100 during the movement, when the sliding block 200 slides towards the matching part 110, the sliding block 200 and the matching part 110 jointly clamp the two adjacent modules, after the clamping action is completed, the sliding block 200 slides away from the matching part 110, so as to separate the clamping tool 10 from the modules, finally, the clamped modules are hoisted into the shell by a crane, and the assembly is completed.
