[0042] In this embodiment, an elastic foot 203 is arranged at the bottom of the sinker 2, so that it has a certain elasticity to better realize these actions when pressing the yarn and resetting. When pressing the yarn, it has a rebound force on the pressed coil and is not easy to damage the coil.

[0043] In this embodiment, the front ends of the elastic legs 203 and the front ends of the sheet body 202 are both connected to the sinker head 201 , and the rear ends of the elastic legs 203 are separated from the sheet body 202 .

[0044] like Figures 4 to 6 As shown, in this embodiment, the bottom of the sinker 2 is connected to the insert 5 through the clamping assembly 4. Specifically, the clamping assembly 4 includes a clamping slot 1 401, a pressing slot 402 and a clamping slot 2 403. The clamping slot 1 401 and the pressing slot 402 are arranged at the bottom of the sinker 2, and the clamping slot 2 403 is arranged on the insert 5. A clamping block 1 404 is clamped in the clamping slot 1 401, and a positioning block 405 is integrally formed at the bottom of the clamping block 1 404. A pressure plate 406 is arranged at the rear of the positioning block 405. The pressure plate 406 is fixed to the positioning block 405 by bolts, and the upper end of the pressure plate 406 is against the side wall of the pressing slot 402; a clamping block 2 407 is connected to the bottom of the positioning block 405 by bolts, and the clamping block 2 407 is clamped and matched with the clamping slot 2 403.

[0045] In this embodiment, the first card slot 401 is a half-dovetail type, and the second card slot 403 is a dovetail type.

[0046] In this embodiment, a stopper 408 is integrally formed at the rear of the positioning block 405 , and the stopper 408 abuts against the head of the insert 5 .

[0047] The installation process of the clamping assembly 4 is as follows: the clamping block 407 is inserted into the clamping slot 403 at the head of the insert 5, a positioning block 405 is placed above the clamping block 407, and the positioning block 405 and the clamping block 407 are locked with bolts, the clamping slot 401 on the needle plate 1 is inserted into the clamping block 404 at the top of the positioning block 405, and finally the pressing plate 406 is installed behind the positioning block 405. Under the locking of the bolts, the needle plate 1 gradually fits the positioning block 405, and the installation of the needle plate is completed. It should be noted that the insert 5 belongs to the prior art, and those skilled in the art can know its structure and function.

[0048] Embodiment 2

[0049] like Figure 7 and 8 As shown, in this embodiment, the sinker 2 is pushed to move in the sheet groove 101 by means of an external push pin. Specifically, two side-by-side pressing grooves 102 are arranged on the top of the needle plate 1. The pressing grooves 102 vertically penetrate a number of sheet grooves 101. Pressing wires 3 are arranged in the pressing grooves 102. The pressing wires 3 are pressed against a number of sinkers 2. The pressing wires 3 can be specifically made of steel wires. Two guide grooves 202-1 are arranged in sequence at the top of the sheet body 202. The two guide grooves 202-1 are pressed against the corresponding pressing wires 3 respectively, and an arc-shaped boss 202-2 is arranged in the guide groove 202-1 at the rear.

[0050] In this embodiment, the wire pressing groove 102 is a dovetail groove, and the dovetail structure is used as the upper and lower positioning of the wire pressing 3. When installing the wire pressing 3, after the wire pressing 3 is inserted from one end of the wire pressing groove 102, a screw is installed at both ends of the wire pressing groove 102 to block the wire pressing 3, so as to limit the position of the wire pressing 3.

[0051] In this embodiment, a pin 202 - 3 that is pushed and matched with an external push pin is disposed on the top of the sheet body 202 ; the pin 202 - 3 is located between the two guide grooves 202 - 1 .

[0052] like Fig. 9 As shown, the sinker 2 is in the reset state, and the sinker 2 is hidden in the tooth plate 6 to avoid the knitting needle and the sinker 2 colliding when the needle is out. At this time, the sinker 2 avoids contact with the tooth steel wire 601.

[0053] like Fig.10 As shown, the sinker 2 is in the state of letting the tooth opening wire open. When the knitting needle rises and the needle is pulled out, the pin 202-3 on the sinker 2 is pushed by the external push pin to realize the forward movement of the sinker. Since the sinker 2 is provided with an arc-shaped boss 202-2, when the sinker 2 is pushed by the push pin to the arc-shaped boss 202-2 and contacts the rear pressing wire 3, the tail of the sinker 2 is pressed down and the head is lifted up to let the tooth opening wire 601 in the tooth opening piece 6 open, so as to prevent the sinker 2 from colliding with the tooth opening wire 601.

[0054] like Fig.11 As shown, the sinker 2 is in the coil pressing state, and the push pin continues to push the sinker 2 to move out of the arc-shaped boss 202-2. At this time, the tail of the sinker 12 bounces up under the action of the elastic support foot 203, and the head of the sinker 12 is pressed down to realize the coil pressing action.

[0055] The remaining structures in this embodiment are the same as those in the first embodiment and will not be described again.

[0056] It should be noted that the toothed plate 6 is installed at the head of the inserting plate 5 . The toothed plate 6 belongs to the prior art, and those skilled in the art are aware of its structure and function.

[0057] Embodiment 3

[0058] The number of the pressing concave points 201-1 on the sinker head 201 directly affects the installation method of the pressing coil device. Based on the technical solution disclosed in the second embodiment, in this embodiment, the number of the pressing concave points 201-1 on the sinker head 201 is further set. Specifically, Fig.12 and 13 As shown, two pressing concave points 201-1 are provided at the lower end of the sinker head 201. During installation, the coil pressing device is only installed on the plug-in piece 5 on one side (not installed on the plug-in piece 5 on the other side). During operation, the two pressing concave points 201-1 on the sinker head 201 press the left coil and the right coil respectively.

[0059] The remaining structures in this embodiment are the same as those in the second embodiment and will not be described again.

[0060] Embodiment 4

[0061] In this embodiment, Fig.14 and 15 As shown, a pressing concave point 201-1 is provided at the lower end of the sinker head 201. During installation, coil pressing devices are installed on the inserts 5 on both sides. The pressing concave point 201-1 on the left side of the sinker head 201 presses the left coil, and the pressing concave point 201-1 on the right side of the sinker head 201 presses the right coil.

[0062] The remaining structures in this embodiment are the same as those in the second embodiment and will not be described again.

[0063] Embodiment 5
