DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1

[0028] In one embodiment, Figure 1-Figure 5 As shown, a needle seat fixing structure includes a first fixing mechanism and a second fixing mechanism, wherein the first fixing mechanism is arranged in the needle seat 101, and the first fixing mechanism can fix and limit the pin header 100 to prevent the pin header 100 from sliding in the needle seat 101, and the second fixing mechanism is arranged on both sides of the needle seat 101, and the second fixing mechanism can limit the distance between the needle seat 101 and the needle mother 201, ensuring that the pin header 100 is in close contact with the needle mother 201 to prevent poor contact, and the needle seat 101 is provided with a through hole 102, and the pin header 100 is slidably arranged in the through hole 102, and the bottom of the pin header 100 is plugged and matched with the needle mother 201;

[0029] The first fixing mechanism includes a pull rod 401, a pull plate 402, a second clamping block 403 and a first spring 404;

[0030] The second fixing mechanism includes a special-shaped spring 303 and a first clamping block 304 .

[0031] like Figure 1 and Figure 3 As shown, the pull rod 401 passes through the needle seat 101 and is fixedly connected with the pull plate 402. A sliding groove is provided inside the needle seat 101. The pull plate 402 is slidably connected to the sliding groove. The pull plate 402 is fixedly connected to one end of the first spring 404 near the side of the needle row 100, and the other end of the first spring 404 is fixedly connected to the second clamping block 403. The needle row 100 penetrates from the top of the needle seat 101 and passes out from the bottom of the bottom end 101 of the needle seat. The second clamping block 403 is clamped with the second clamping groove 405, which is convenient for fixing the needle row 100. When the needle seat 101 needs to be replaced, the pull rod 401 is pulled to drive the pull plate 402 to move in the sliding groove, thereby driving the second clamping block 403 to slide out of the second clamping groove 405, thereby releasing the fixation of the needle row 100.

[0032] like Figure 3As shown, two second slots 405 are symmetrically provided on the pin header 100 , and the size of the second slots 405 matches the size of the second block 403 , so that the second block 403 can be snapped into the second slots 405 to fix the pin header 100 and prevent the pin header 100 from sliding in the through hole 102 .

[0033] like Figure 1 As shown, the special-shaped spring 303 is arranged on the outside of the needle seat 101, and two first clamping blocks 304 are provided at the bottom of the special-shaped spring 303. Pressing the special-shaped spring 303 can compress the special-shaped spring 303 to generate elastic force, and at the same time, the two first clamping blocks 304 can be brought close to each other, so as to facilitate the clamping and fixing of the first clamping block 304 and the first clamping groove 305.

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the needle nut 201 is provided with a plug-in groove 202 corresponding to the perforation 102, and fixed seats 301 are fixed on both sides of the needle nut 201. A groove 302 is provided on the fixed seat 301, and a first clamping groove 305 is provided inside the fixed seat 301, and the groove 302 is communicated with the first clamping groove 305. The special-shaped spring 303 is pressed, and the two first clamping blocks 304 are close to each other, so that the first clamping block 304 is inserted into the groove 302, and then the special-shaped spring 303 is released. The elastic force of the special-shaped spring 303 drives the first clamping block 304 to move away from each other and clamp with the first clamping groove 305. When it is necessary to release the fixation of the needle seat 101 and the needle nut 201, the special-shaped spring 303 is pressed again to make the first clamping block 304 slide out of the first clamping groove 305, and the fixation of the first clamping groove 305 to the first clamping block 304 is released.

[0035] Example 2

[0036] The difference from Example 1 is that Figure 3 and Figure 4 As shown, four installation grooves are opened in the needle seat 101, and a sliding sleeve 502 is fixedly provided in the installation groove. A sliding rod 503 is slidably provided in the sliding sleeve 502, and the sliding rod 503 is fixedly connected to the pull plate 402. The cooperation between the sliding sleeve 502 and the sliding rod 503 can enhance the stability of the pull plate 402 when it moves. The pull plate 402 is fixedly connected to the needle seat 101 through the second spring 501. The setting of the second spring 501 can make the pull plate 402 move toward the direction close to the needle row 100, so as to facilitate the clamping and fixing of the second clamping block 403 and the second clamping groove 405.

[0037] like Figure 2 As shown, the dimensions of the through hole 102 and the plug-in slot 202 match the dimensions of the pin header 100 .

[0038] like Figure 5As shown, the size of the first card slot 305 is matched with the size of the first card block 304 .

[0039] Working principle: When in use, the pin header 100 is passed through the needle seat 101, and the pin header 100 is fixed by the engagement of the second clamping block 403 and the second clamping groove 405. Then, the needle seat 101 with the pin header 100 installed is placed corresponding to the needle mother 201, so that the bottom end of the pin header 100 is inserted into the plug-in groove 202, and at the same time, the special-shaped spring 303 is pinched to make the two first clamping blocks 304 approach each other. After the first clamping block 304 is inserted into the groove 302, the special-shaped spring 303 is released. The elastic force of the special-shaped spring 303 itself controls the two first clamping blocks 304 to move away from each other, so that the first clamping block 304 is engaged with the first clamping groove 305, and the needle seat 101 is fixed to prevent the needle seat 101 and the needle mother 201 from offset.
