The capacitive sensor 5 is embedded in the interior of the clamp 403. According to the size of the capacitive sensor 5, the slider 404 is pushed to drive the outside of the clamp 403 connected by the threaded bolt to slide in the direction of the capacitive sensor 5. At this time, the capacitive sensor 5 is clamped and fixed.

[0029] Example 2

[0030] like Figure 3 to Figure 5As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the top of the base 2 is fixed to the lifting module 201 by welding, the front side of the lifting module 201 is fixed with an extension rod 202 by welding, the front end outer side of the extension rod 202 is slidably inserted into the fixing seat 203, the inside of the fixing seat 203 is provided with a round hole, the inside of the round hole of the fixing seat 203 is slidably connected with an extension rod 204, the outside of the extension rod 204 is sleeved with a first spring 205, the front end of the extension rod 204 is fixed to a base 206 by welding, the inside of the base 206 is provided with a slide groove, the inside of the slide groove of the base 206 is slidably connected with a puncher 207, and the top of the puncher 207 is fixed by a threaded bolt. A fixed end head 208 is provided, and a circular hole is provided at the top of the base 206, a slide rod 301 is slidably connected inside the circular hole of the base 206, the outer side of the slide rod 301 is fixedly connected to the partition plate 302 and is arranged inside the slide rod 301, a second spring 303 is sleeved on the outer side of the slide rod 301, the bottom end of the second spring 303 is tightly set on the top of the clamping plate 3, the clamping plate 3 is fitted on the top of the base 206, the bottom end of the slide rod 301 is fixed with a fixing frame 304 by welding, the bottom end of the fixing frame 304 is rotatably connected with a rotating wheel 305, the rotating wheel 305 is tightly pressed against the outer side of the puncher 207, six groups of clamps 4 and capacitive sensors 5 are provided, and are evenly arranged on the outer side of the turntable 1.

[0031] In this embodiment, the puncher 207 inside the sliding base 206, at this time, the top of the puncher 207 lifts up the rotating wheel 305 inside the fixing frame 304, and at this time, the rotating wheel 305 lifts the slide bar 301 to slide in the direction of the partition 302. At this time, the slide bar 301 slides inside the clamping plate 3 and cooperates with the second spring 303 to clamp the partition 302. At this time, the puncher 207 slides in the slide groove inside the base 206, and the puncher 207 can be moved. At this time, adding a group of punchers 207 can realize the welding and fixing of the end 208 at the top of the puncher 207 to the electrode 501 on the outside of the capacitive sensor 5.

[0032] The working principle of this utility model:

[0033] First, the staff places the base 2 on the workbench, and sets up two groups on the outside of the top of the turntable 1, inserts the threaded shaft 401 into the inside of the screw 402, and inserts it into the inner thread groove of the turntable 1, and tightens the screw 402 on the outside of the threaded shaft 401 to clamp the splint 4, and embeds the capacitive sensor 5 in the inside of the fixture 403. According to the size of the capacitive sensor 5, push the slider 404 to drive the outside connected with the fixture 403 by the threaded bolt to slide in the direction of the capacitive sensor 5, and then clamp the capacitive sensor 5. Similarly, the six groups of splints 4 on the outside of the turntable 1 are respectively installed on the outside of the turntable 1. At this time, the turntable 1 is pushed to rotate, and the end 208 at the top of the punch 207 welds and fixes the electrode 501 on the outside of the capacitive sensor 5.

[0034] When the position of the punch 207 is low, the electrode 501 on the outside of the capacitive sensor 5 cannot be welded. The lifting module 201 at the top of the base 2 is moved this time. The extension rod 202 at the front end of the lifting module 201 is inserted into the circular hole inside the fixed seat 203. At this time, the height of the fixed seat 203 is increased, and the extension rod 204 at the top of the fixed seat 203 is inserted into the circular hole inside the base 206. When the end 208 at the top of the punch 207 welds and fixes the electrode 501 on the outside of the capacitive sensor 5, the reaction force generated by the end 208 reduces shock and buffers the base 206.

[0035] When the end 208 at the top of the puncher 207 is welding and fixing the electrode 501 on the outside of the capacitive sensor 5, if the electrodes 501 on both sides of the capacitive sensor 5 are too close, it is only necessary to slide the puncher 207 inside the base 206. At this time, the top of the puncher 207 lifts up the rotating wheel 305 rotating inside the fixing frame 304. At this time, the rotating wheel 305 lifts the sliding rod 301 to slide in the direction of the partition 302. At this time, the sliding rod 301 slides inside the abutting plate 3, and the second spring 303 abuts against the partition 302. At this time, the puncher 207 slides in the sliding groove inside the base 206, so that the puncher 207 can be moved. At this time, adding a group of punchers 207 can realize that the end 208 at the top of the puncher 207 can be welded and fixed to the electrode 501 on the outside of the capacitive sensor 5, which can solve the problem that the position of the electrodes 501 is too concentrated and welding is inconvenient.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
