DETAILED DESCRIPTION
[0034] In order to make the personnel in the technical field better understand the utility model scheme, below will combine the figures in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor should belong to the scope of the utility model protection.
[0035] As Figures 1-3 The elastic pen clamp includes pressing part 1, clamping part 2 and connecting part 3, at least part of clamping part 2 is bent, clamping part 2 is connected with pressing part 1 and extends to the direction of pen barrel 4, which is used for clamping object with pen barrel 4. The upper part of connecting part 3 is connected with pressing part 1, the lower part of connecting part 3 is connected with pen barrel 4, and connecting part 3 has at least arc connecting section 31.
[0036] When the pressing part 1 is pressed by an external force, the arc-shaped connecting section 31 of the connecting part 3 is deformed, and the end of the clamping part 2 moves away from the pen barrel 4, so that a gap 5 is formed between the end of the clamping part 2 and the pen barrel 4. When it is necessary to clamp an object, the object can be inserted into the gap 5 during the pressing of the pressing part 1. Once the pressing part 1 is reset upward, the clamping part 2 and the pen barrel 4 clamp the object. If it is not necessary to clamp the object, and only the pressing part 1 is pressed to make the lead core extend out of the shaft of the pen barrel 4, the gap 5 is formed between the end of the clamping part 2 and the pen barrel 4, so that the end of the clamping part 2 does not contact the pen barrel 4, preventing the clamping part 2 from moving up and down relative to the pen barrel 4, which causes the wear of the outer surface of the pen barrel 4, prolongs the service life of the pen barrel 4, and ensures the aesthetic appearance of the pen barrel 4.
[0037] In the above structure, only the clamping part 2 and the connecting part 3 are connected with the pressing part 1, and it is not limited whether they are directly connected or indirectly connected, or whether they are separately arranged or integrally arranged. In this embodiment, the clamping part 2, the pressing part 1 and the connecting part 3 are integrally connected, and the three are formed by bending a steel wire, which is a common steel wire in the prior art, having a certain hardness and being able to be deformed under the action of an external force.
[0038] Specifically, as shown in Figure 3 , Figure 6 , the clamping part 2 is arranged in a circular arc shape, and the entire clamping part 2 is arranged in a circular arc shape, and the curved concave surface 21 faces the direction of the pen barrel 4. Of course, in other embodiments, the clamping part 2 can be arranged in other forms, such as a right-angle bend, an obtuse-angle bend, etc., and the specific form is not limited.
[0039] The connecting part 3 not only has the arc-shaped connecting section 31, but also includes a V-shaped bending section 32; taking the direction shown in Figure 3 as an example, the concave surface 311 of the arc-shaped connecting section 31 faces the same direction as the curved concave surface 21 of the clamping part 2; as shown in Figure 11 , Figure 12 , when the elastic pen clip is assembled and connected with the pen barrel 4, the closed end 33 of the V-shaped bending section 32 abuts against the inner wall of the pen barrel 4, one open end of the V-shaped bending section 32 is connected with the arc-shaped connecting section 31, and the other open end abuts against the pen barrel 4, and the opening of the V-shaped bending section 32 faces the opposite direction of the concave surface 311 of the arc-shaped connecting section 31. In other words, the connecting part 3 is in the shape of “S” or the mirror image of “S”. When the pressing part 1 is pressed by an external force, the arc-shaped connecting section 31 of the connecting part 3 is deformed, and the V-shaped bending section 32 is also deformed, and the deformation of the V-shaped bending section 32 has a beneficial effect on the deformation of the arc-shaped connecting section 31, so that the arc-shaped connecting section 31 can be deformed more greatly after being pressed, and specifically, the part of the arc-shaped connecting section 31 connected with the pressing part 1 tends to move downward and to the left (taking the direction shown in Figure 12The direction shown is an example, so that the end of the clamping part 2 can be driven to move away from the pen barrel 4.
[0040] Of course, the design of the V-shaped bending section 32 also facilitates the assembly and connection of the elastic pen holder and the pen barrel 4. The press-moving structure inside the pen barrel 4 can be realized by the prior art, and will not be described in detail. Here, the pen barrel 4 includes an external barrel body and an internal structure. An installation cavity 42 is formed in the pen barrel 4, and a mounting opening 422 is formed on the side of the installation cavity 42. The closed end 33 of the V-shaped bending section 32 is first inserted into the installation cavity 42 from the mounting opening 422. Under the action of external force, the open end of the V-shaped bending section 32 becomes smaller, thereby being squeezed into the installation cavity 42. Once it is completely inserted into the installation cavity 42, the open end of the V-shaped bending section 32 abuts against the protrusion 421 inside the installation cavity 42, thereby preventing the V-shaped bending section 32 from being separated from the pen barrel 4. The closed end 33 of the V-shaped bending section 32 always abuts against the inner wall of the pen barrel 4, so that the assembly structure of the connecting part 3 and the pen barrel 4 is relatively stable, and the elastic pen holder will not shake.
[0041] As shown in Figure 3 , the pressing part 1 is an arc-shaped bending structure. Specifically, the arc-shaped connecting section 31 has a length that is approximately parallel to the bending extension direction of the clamping part 2.
[0042] In order to improve the use feeling and also to improve the aesthetic degree, the pressing part 1 is externally sleeved with a pressing sphere 11. In the initial state, the center of the pressing sphere 11 is radially close to the central axis of the pen barrel 4, as shown in Figure 5 , Figure 8 , the central axis of the pen barrel 4 is the O line, which passes through the center point of the pressing sphere 11. Even if the center point of the pressing sphere 11 does not pass through the O line, it is close to the O line.
[0043] The end of the clamping part 2 is sleeved with a clamping sphere 22, which can cooperate with the pen barrel 4 to clamp objects. The contact area with the objects can be increased, and the clamping stability can be increased.
[0044] As shown in Figures 4-7 , a writing pen includes a pen barrel 4 and the above-mentioned elastic pen holder. As shown in Figure 9 , Figure 10 , the top end of the pen barrel 4 is formed with a moving groove 41 along the axial direction. The top end of the moving groove 41 has an open slot 411. The connecting part 33 extends from the moving groove 41 and can move axially in the moving groove 41. Due to the arrangement of the open slot 411, the arc-shaped connecting section 31 of the connecting part 3 can also extend into the moving groove 41 during the downward movement of the elastic pen holder, avoiding interference between the elastic pen holder and the pen barrel 5, so that the up-down movement range of the pressing part 1 is larger.
[0045] In Figure 11 As an example in the direction shown, in use, the pressing ball 11 on the pressing part 1 is pressed down under an external force, the arc connecting section 31 of the connecting part 3 is deformed downward, that is, the curvature of the concave surface 311 of the arc connecting section is increased, since the clamping part 2 is connected with the connecting part 3 into an integral body through the pressing part 1, the pressing part 1 is driven to move downward to drive the lower end of the clamping part 2 to rotate counterclockwise along the arrow direction, that is, the lower end of the clamping part 2 is driven to move away from the pen barrel 4, so that a gap 5 is formed between the end of the clamping part 2 and the pen barrel 4, that is, in the process of pressing down to realize the extension of the pen core out of the pen barrel 4, the lower end of the clamping part 2 does not contact with the outer wall of the pen barrel 4, so that the outer wall of the pen barrel 4 is not abraded.
[0046] In addition, the pressing part 1 is pressed down to realize the opening of the clamping part 2, so that the clamping part 2 and the pen barrel 4 can clamp the object.
[0047] The above specific embodiment is used to explain and illustrate the present application, but is not used to limit the present application, any modification and change made to the present application within the spirit and protection scope of the claims of the present application all fall into the protection scope of the present application.
