DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] In order to understand the technical means of the present disclosure more clearly and implement the technical means according to contents in the specification, specific implementations of the present disclosure will be further described below in detail with reference to the accompanying drawings and embodiments. The embodiments described below are intended to illustrate the present disclosure, rather than limit the scope of the present disclosure.

[0036] A rear-pressing anti-misoperation double-ended eyebrow pencil provided by the present disclosure is described in detail in a specific embodiment. As shown in FIG. 1 to FIG. 12, the rear-pressing anti-misoperation double-ended eyebrow pencil includes nib 1, front lid 2, piston 3, intermediate ring 4, pencil body 5, threaded rod 6, nut 7, first spring 8, ratchet wheel 9, ratchet seat 10, ratchet rod 11, shoulder sleeve 12, bristle carrier 13, bristle 14, inner sleeve 15, tail lid 16, and button 17. The intermediate ring 4 is shaped as a hollow rod and sleeved on the hollow pencil body 5. The nib 1 is a hollow structure and is provided at one end of the pencil body 5. Material 18 is provided in the nib 1 and adjacent to an outlet. The front lid 2 is detachably provided at an end of the pencil body 5 adjacent to the nib 1. The front lid 2 can overlay the nib 1. The front lid 2 can protect the nib 1. The nut 7 is provided in the pencil body 5. A screw thread is provided on an inner side of the nut 7. The threaded rod 6 is provided with a screw thread and rotatably provided on the nut 7. The nut can axially move through rotation of the threaded rod 6. One end of the piston 3 abuts against the material 18, and the other end of the piston 3 abuts against the threaded rod 6. The piston 3 can move to the outlet under pushing of the threaded rod 6. The material 18 can move out of the outlet under pushing of the piston 3. The piston 3 is configured to push out the material 18. The ratchet wheel 9 and the first spring 8 are sleeved on the threaded rod 6. Two ends of the first spring 8 respectively abut against the nut 7 and the ratchet wheel 9. The ratchet wheel 9 is slidably provided on the threaded rod 6 and circumferentially fixed with the threaded rod 6. The ratchet rod 11 is shaped as a hollow rod. One end of the threaded rod 6 is inserted into the ratchet rod 11. The threaded rod 6 can axially move and rotate in the ratchet rod 11. The ratchet seat 10 is shaped as a hollow ring and provided in the pencil body 5. One end of the ratchet rod 11 is inserted into the ratchet seat 10. An end of the ratchet wheel 9 adjacent to the ratchet rod 11 is provided with first unidirectional jump tooth 91. An end of the ratchet rod 11 adjacent to the ratchet wheel 9 is provided with ratchet 111. Second unidirectional jump tooth 101 is provided inside an end of the ratchet seat 10 adjacent to the ratchet wheel 9. The ratchet wheel 9 can rotate under pushing of the ratchet rod 11. Through cooperation between the ratchet 111 and the first unidirectional jump tooth 91, the ratchet wheel 9 can be driven, thereby driving the threaded rod 6 to rotate and pushing the material 18 to discharge. The first unidirectional jump tooth 91 can be clamped into the second unidirectional jump tooth 101. The second unidirectional jump tooth 101 can ensure that the ratchet wheel 9 has a same angle in each rotation and a same amount in each discharge. The shoulder sleeve 12 is provided at an end of the pencil body 5 away from the nib 1. An end of the ratchet rod 11 away from the ratchet 111 penetrates through the shoulder sleeve 12. The bristle carrier 13 is sleeved on the end of the ratchet rod 11 away from the ratchet 111. The bristle carrier 13 and the ratchet rod 11 are circumferentially fixed. The bristle 14 is provided on the bristle carrier 13. The tail lid 16 is detachably provided at an end of the pencil body 5 adjacent to the bristle carrier 13. The tail lid 16 can overlay the bristle 14. While protecting the bristle 14, the tail lid 16 is provided with the button 17. The button 17 is provided at an end of the tail lid 16. The inner sleeve 15 is slidably provided in the tail lid 16. One end of the inner sleeve 15 abuts against the bristle carrier 13, and the other end of the inner sleeve 15 is connected to the button 17. The ratchet rod 11, the ratchet wheel 9, the bristle carrier 13 and the inner sleeve 15 can axially move toward the material 18 under pushing of the button 17 and are restored through an elastic force of the first spring 8. The ratchet rod 11, the ratchet wheel 9, the bristle carrier 13 and the inner sleeve 15 transfer a pressure of the button 17 layer by layer, such that the ratchet wheel 9 rotates, thereby driving the threaded rod 6 to rotate and pushing out the material 18. Then, the ratchet rod, the ratchet wheel, the bristle carrier and the inner sleeve are restored through the elastic force of the first spring 8, thereby realizing a rear-pressing discharge function. The bristle carrier 13 and the shoulder sleeve 12 are provided with a locking device. In response to a locked state of the locking device, the bristle carrier 13 and the shoulder sleeve 12 are axially fixed. The locking device can prevent misoperation. When the bristle carrier 13 and the shoulder sleeve 12 are axially fixed, the bristle carrier 13 neither moves axially, nor pushes the ratchet rod 11. Therefore, the ratchet rod 11 does not push the ratchet wheel 9 to rotate to discharge the material 18, thus preventing a waste. The present disclosure is advantageous for easy operation, stable discharge and an anti-misoperation function.

[0037] In the embodiment, preferably, the locking device includes rotating rib 121 and stepped limit portion 131 cooperating with the rotating rib 121. The rotating rib 121 is provided inside the shoulder sleeve 12. The stepped limit portion 131 is provided at an end of the bristle carrier 13 away from the bristle. The shoulder sleeve 12 is rotatably connected to the pencil body 5. The shoulder sleeve 12 and the tail lid 16 are circumferentially fixed. The rotating rib 121 can move in or out of the stepped limit portion 131 under driving of the tail lid 16. By rotating the tail lid 16 circumferentially fixed with the shoulder sleeve 12, the rotating rib 121 can be clamped into the stepped limit portion 131, thereby preventing the bristle carrier 13 from axially moving. By reversely rotating the tail lid 16 circumferentially fixed with the shoulder sleeve 12, the rotating rib 121 can move out of the stepped limit portion 131, such that the bristle carrier 13 moves axially and smoothly to prevent misoperation.

[0038] In the embodiment, preferably, the shoulder sleeve 12 and the tail lid 16 are circumferentially fixed through a stopping rib. Through the stopping rib, the shoulder sleeve 12 and the tail lid 16 are circumferentially fixed more firmly.

[0039] In the embodiment, preferably, second spring 19 is provided between the tail lid 16 and the inner sleeve 15. The second spring 19 can pull the button 17 on the inner sleeve 15 into the tail lid 16. With the second spring 19, when the tail lid 16 is taken down from the pencil body 5, the button 17 can be pulled back to the tail lid 16 through a tensile force of the second spring 19, thereby protecting the button 17.

[0040] In the embodiment, preferably, the bristle carrier 13 and the ratchet rod 11 are circumferentially fixed through a stopping rib. Through the stopping rub, the bristle carrier 13 and the ratchet rod 11 are circumferentially fixed more firmly.

[0041] In the embodiment, preferably, the tail lid 16 is connected to the shoulder sleeve 12 through a clamping point. Through the clamping point, the tail lid 16 and the shoulder sleeve 12 are connected more firmly, and are assembled more conveniently.

[0042] In the embodiment, preferably, the inner sleeve 15 is connected to the button 17 through a fastener. With the fastener, the inner sleeve 15 and the button 17 are connected more firmly, and are assembled more conveniently.

[0043] In the embodiment, preferably, the intermediate ring 4 is made of aluminum. The intermediate ring 4 made of aluminum can be more wear-resistant with a higher strength.

[0044] In the embodiment, preferably, weight 20 is further provided in the pencil body 5. The weight 20 is provided between the nib 1 and the nut 7. With the weight 20 between the nib 1 and the nut 7, a barycenter of the pencil body 5 can be balanced for sake of better coordination in use.

[0045] The rear-pressing anti-misoperation double-ended eyebrow pencil in the embodiment is advantageous for easy operation, stable discharge and an anti-misoperation function.
