In some embodiments of the present utility model, as shown in fig. 1-2, a push-type pen is provided, including a barrel 100, a nib 200, a first resilient element 300, and a ball 400. A liquid storage cavity 110 for storing ink and a pushing mechanism 500 for pushing the ink are arranged in the pen tube 100. The pushing mechanism 500 is disposed at one side of the liquid storage chamber 110. One end of the pen head 200 is inserted into the liquid storage cavity 110. One end of the pen head 200 is provided with a circulation groove 210 for flowing ink. One end of the first elastic member 300 is connected to the inner wall of the flow channel 210. The steel ball 400 is connected to the other end of the first elastic member 300. The steel ball 400 seals the inlet of the circulation groove 210 under the supporting action of the first elastic member 300, thereby preventing the ink in the liquid storage chamber 110 from flowing into the circulation groove 210.

Under the supporting action of the first elastic member 300, the steel ball 400 seals the inlet of the circulation groove 210, and the ink in the liquid storage cavity 110 is blocked by the steel ball 400 and cannot flow into the circulation groove 210. Due to the blocking effect of the steel ball 400 on the ink, the pen point 200 and the liquid storage cavity 110 have better sealing performance, so that the condition of ink leakage is avoided.

When it is desired to use the eyeliner, the pushing mechanism 500 is pressed, and the pushing mechanism 500 moves toward the liquid storage chamber 110 and presses the liquid storage chamber 110. The ink is extruded to move toward the circulation groove 210 and push the steel ball 400, the first elastic member 300 is changed from an original state to a compressed state, the ink flows toward the pen head 200 through the circulation groove 210, when the pushing mechanism 500 is not pressed any more, the ink does not press the steel ball 400 any more, the first elastic member 300 is changed from the compressed state to the original state and pushes the steel ball 400 to reset, the steel ball 400 blocks the inlet of the circulation groove 210 again, and the ink is blocked by the steel ball 400 and cannot flow into the circulation groove 210 any more.

In other embodiments of the present utility model, as shown in fig. 2-3, the pushing mechanism 500 includes a drive shaft 510 and a dental shaft 520. The transmission shaft 510 is installed in the pen tube 100, and one end of the transmission shaft penetrates out of the pen tube 100. The inside of the driving shaft 510 is provided with a fixing groove 511. The outer surface of the dental shaft 520 is provided with fixing teeth 521. One end of the dental shaft 520 is inserted into the fixing groove 511 and abuts against the wall of the liquid storage chamber 110. The fixing teeth 521 are engaged with the fixing grooves 511, thereby fixing the driving shaft 510 and the tooth shaft 520 to each other. When the transmission shaft 510 is pressed, the transmission shaft 510 drives the tooth shaft 520 to move toward the liquid storage cavity 110 and squeeze the liquid storage cavity 110, so that the ink in the liquid storage cavity 110 flows out.

In other embodiments of the present utility model, as shown in fig. 2-3, the pushing mechanism 500 further includes a second elastic member 530 and a limiting member 540. One end of the second elastic member 530 is connected to the driving shaft 510. The limiting piece 540 is connected with the liquid storage cavity 110, the limiting piece 540 is further connected with the other end of the second elastic piece 530, the limiting piece 540 is spaced and opposite to the transmission shaft 510, and one end of the dental shaft 520 passes through the limiting piece 540 and is abutted to the cavity wall of the liquid storage cavity 110. When the transmission shaft 510 is pressed to move toward the liquid storage cavity 110, the distance between the transmission shaft 510 and the limiting member 540 is continuously shortened, and the second elastic member 530 is changed from the original state to the compressed state. Until the transmission shaft 510 contacts the stopper 540, the transmission shaft 510 is stopped from moving by the stopper 540. Excessive extrusion of the drive shaft 510 to the reservoir 110 is avoided due to the blocking effect of the stopper 540.

When the driving shaft 510 is not pressed any more, the second elastic member 530 is restored from the compressed state, thereby automatically resetting the driving shaft 510.

In other embodiments of the present utility model, as shown in fig. 2-3, the limiting member 540 is provided with a first clamping groove 541. The other end of the transmission shaft 510 is provided with a first clamping tooth 512. When the transmission shaft 510 moves toward the limiting member 540, the first clamping teeth 512 are inserted into the first clamping grooves 541. The combination of the first clamping teeth 512 and the first clamping grooves 541 enables the limiting member 540 to be tightly attached to the transmission shaft 510.

In other embodiments of the present utility model, as shown in fig. 1-3, the push mechanism 500 further includes a press cap 550 and an abutment block 560. The cap 550 is connected to an end of the transmission shaft 510 that extends out of the pen holder 100. The pressing cap 550 increases the force receiving area of the finger when pressed, thereby reducing pain when the hand presses the transmission shaft 510. One end of the press cap 550 is extended outwards to form an extension bar 551. The abutment block 560 is mounted on the drive shaft 510, and a guide groove 561 is provided at the other end of the abutment block 560. The extension bar 551 is slidably received in the guide groove 561. When the press cap 550 is pressed, the extension bar 551 slides into the guide groove 561. Due to the limiting action of the two sides of the guide groove 561 on the extension bar 551, the extension bar 551 can only slide linearly in the guide groove 561, so that the press cap 550 moves linearly more stably when pressed.

In other embodiments of the utility model, as shown in FIG. 2, the outer surface of the drive shaft 510 bulges outwardly to form a mounting platform 513. One side of the mounting base 513 is connected to the abutment block 560, and the other side is connected to the second elastic member 530.
