The slider 301 is movably mounted on the top of the base plate 1, and the first gear 302 is movably mounted on one side of the slider 301, and the first bracket 303 is fixedly mounted on one side of the first gear 302. The second bracket 304 is provided at the bottom of the first bracket 303, and the first side brackets 303 and the second bracket 304 are fixedly mounted on the left and right sides. Plate 305, a first clamping block 306 is movably installed on one side of the first side plate 305, and a second clamping block 307 is movably connected to one side of the first clamping block 306. A positioning groove 308 is provided on one side of the first clamping block 306 and the second clamping block 307. The second clamping block 307 is movably installed on one side of the second side plate 309. The second side plate 309 is fixedly connected to the first side plate 305 through a cylinder. A limiting tube 311 is fixedly connected to one side of the second side plate 309. A pull rod 312 is movably installed inside the limiting tube 311. One side of the pull rod 312 is fixedly connected to the limiting ring 313, and the other side of the pull rod 312 is fixedly connected to the handle 310. A first spring 314 is provided on one side of the limiting ring 313. One side of the first spring 314 is fixedly connected to one side of the limiting ring 313, and the other side of the first spring 314 is fixedly connected to one side of the handle 310.

[0034] The first clamp 31 and the second clamp 32 also include a positioning block 315, a first clamp 316, a limiting rod 317, a second spring 318, a second clamp 319, a first bearing plate 320, a first swivel 321 and a second swivel 322.

One side of the first clamp 316 is movably sleeved on the limiting rod 317. A second spring 318 is provided on one side of the limiting rod 317. The bottom of the limiting rod 317 is fixedly connected to the second clamp 319. One side of the second clamp 319 is fixedly connected to the first bearing plate 320. One side of the first bearing plate 320 is movably sleeved on the first swivel 321, and the other side of the first bearing plate 320 is movably sleeved on the second swivel 322.

[0035] The first bearing plate 320 is movably connected to one side of the first clamping plate 316 , the top of the second spring 318 is fixedly connected to the bottom of the first clamping plate 316 , and the bottom of the second spring 318 is fixedly connected to the top of the second clamping plate 319 .

[0036] The first clamping block 306 is movably connected to the bottom of the first rotating ring 321 , and the second clamping block 307 is movably connected to the bottom of the second rotating ring 322 .

[0037] What needs to be further explained is that: when the polygonal pipe needs to be fixed, first pull the handle 310 to drive the pull rod 312 out of the inside of the positioning groove 308. At this time, the first clamp 306 and the second clamp 307 are no longer restricted by the pull rod 312. Then place the parts that need to be fixed in the center of the first clamp 306 and the second clamp 307, and use the teeth between the first clamp 306 and the second clamp 307 to fix the parts. Under the action of the second spring 318, the first swivel 321 and the second swivel 322 move downward at the same time, thereby driving the first clamp 306 and the second clamp 307 downward to fix the parts.

[0038] like Figure 7 As shown, the adjustment mechanism 4 includes a base 401, a worm 402, a knob 403, a worm wheel 404, a rotating rod 405, a second gear 406, a third gear 407 and a second bearing plate 408. The base 401 is fixedly mounted on the top of the base plate 1, and the top of the base 401 is movably mounted with a worm 402, which is fixedly mounted on the bottom of the knob 403. One side of the worm 402 is engaged with the worm wheel 404, and one side of the worm wheel 404 is fixedly connected to the rotating rod 405, one side of the rotating rod 405 is fixedly connected to the second gear 406, and the other side of the rotating rod 405 is fixedly connected to the third gear 407. The third gear 407 and the second gear 406 are both movably mounted on one side of the second bearing plate 408, and the second bearing plate 408 is fixedly mounted on the top of the base plate 1.

[0039] The second gear 406 is meshed with the first gear 302 inside the second fixture 32 for transmission, and the third gear 407 is meshed with the first gear 302 inside the first fixture 31 for transmission.

[0040] The rotating rod 405 is disposed on one side of the first bracket 303 , and the length of the third gear 407 is the same as the distance that the slider 301 moves on the top of the base plate 1 .

[0041] It needs to be further explained that: when it is necessary to adjust the angle of the parts fixed on the first clamp 31 and the second clamp 32 for welding, it is only necessary to turn the knob 403 to drive the worm 402 and the worm wheel 404 to engage and transmit, and further drive the rotating rod 405, the second gear 406 and the third gear 407 to rotate at the same time. When the second gear 406 rotates, the first gear 302 inside the second clamp 32 engages and transmits with the second gear 406. When the third gear 407 rotates, the first gear 302 inside the first clamp 31 engages and transmits with the third gear 407, thereby achieving the purpose of rotating the parts clamped on the first clamp 31 and the second clamp 32 at the same time to adjust the angle.

[0042] The working principle and use process of the utility model: During the use of the utility model, the distance between the first clamp 31 and the second clamp 32 is first adjusted by rotating the distance adjusting device 2 to ensure that the parts clamped by the first clamp 31 and the second clamp 32 remain in a fit state.

[0043] Next, pull the handle 310 to drive the pull rod 312 out of the positioning groove 308. At this time, the first clamp 306 and the second clamp 307 are no longer restricted by the pull rod 312. Then place the parts to be fixed in the center of the first clamp 306 and the second clamp 307, and use the teeth between the first clamp 306 and the second clamp 307 to fix the parts. Under the action of the second spring 318, the first swivel 321 and the second swivel 322 move downward at the same time, thereby driving the first clamp 306 and the second clamp 307 downward to fix the parts.

[0044] Finally, when it is necessary to adjust the angle of the parts fixed on the first clamp 31 and the second clamp 32 for welding, it is only necessary to turn the knob 403 to drive the worm 402 and the worm wheel 404 to engage and transmit, and further drive the rotating rod 405, the second gear 406 and the third gear 407 to rotate at the same time. When the second gear 406 rotates, the first gear 302 inside the second clamp 32 engages and transmits with the second gear 406. When the third gear 407 rotates, the first gear 302 inside the first clamp 31 engages and transmits with the third gear 407, thereby achieving the purpose of rotating the parts clamped by the first clamp 31 and the second clamp 32 at the same time to adjust the angle.

[0045] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
