[0030] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. SPECIFIC EMBODIMENTS
[0031] Please refer toFigures 1-9 , in a preferred embodiment of the present utility model, a silver needle trimming device includes a fixed base 1 and a movable base 4 arranged side by side; at least two first rollers 2 are provided on the top surface of the fixed base 1. All the first rollers 2 are arranged on one side of the fixed base 1 close to the movable base 4, and are spaced along a direction perpendicular to the side-by-side direction of the fixed base 1 and the movable base 4. Each first roller 2 is rotatably installed on the fixed base 1. The rotation axes of all the first rollers 2 are parallel to each other. The end faces of all the first rollers 2 facing the side where the movable base 4 is located are located on the same plane, and this plane is the first plane.
[0032] A second roller 5 is arranged between two adjacent first rollers 2. The outer diameter of the second roller 5 is greater than the distance between the outer contours of two adjacent first rollers 2. The second roller 5 is rotatably installed on the top surface of the movable base 4. The end faces of all the second rollers 5 facing the side where the fixed base 1 is located are located on the same plane, and this plane is the second plane. The second plane is parallel to the first plane.
[0033] The movable base 4 is slidably connected to the fixed base 1 through a guide rod 3, and the sliding direction is perpendicular to the first plane; a locking structure is provided on the fixed base 1 to prevent the movable base 4 from sliding relative to the fixed base 1; a return spring 6 is arranged between the movable base 4 and the fixed base 1. The elastic force direction of the return spring 6 is parallel to the sliding direction of the movable base 4; in the natural state of the return spring 6, the movable base 4 and the fixed base 1 are spaced apart, and the second plane is located between the first plane and the end face of the movable base 4 far from the fixed base 1.
[0034] By sliding the movable base 4 relative to the fixed base 1 in the present utility model, the distance between the first plane and the second plane can be adjusted, so as to form a placement space with different widths between the first plane and the second plane, thereby facilitating the placement of silver needles with different thicknesses; when the silver needle falls between the first plane and the second plane, the silver needle is tangent to the outer contours of the first rollers 2 and the second rollers 5. By sliding the silver needle back and forth along the tangential direction of the first rollers 2 and the second rollers 5, the bending condition of the silver needle can be improved under the action of the rotation of the first rollers 2 and the second rollers 5, and the purpose of straightening and trimming the silver needle can be achieved. Compared with the existing method of directly straightening by hand, the straightening effect is better and the efficiency is higher.
[0035] In this embodiment, it is preferred that the outer diameters of all the first rollers 2 are the same. Similarly, it is also preferred that the outer diameters of all the second rollers 5 are the same. In addition, the second plane is located between the movable base 4 and the end face of the fixed base 1 far from the movable base 4. That is, a part of the second roller 5 extends out of the movable base 4. When the movable base 4 is attached to the fixed base 1, a part of the second roller 5 is located above the top surface of the fixed base 1, so as to better retract the movable base 4 and reduce the occupied space of the device. Further, when the movable base 4 is attached to the fixed base 1, the second plane is located between the first plane and the end face of the fixed base 1 far from the movable base 4, and the return spring 6 is in an elastically deformed state. That is, the second roller 5 can move to be close to the space between two adjacent first rollers 2, realizing the minimum retraction of the device. At this time, the straightening operation of the silver needles cannot be realized. After the restriction on the movable base 4 is released, the movable base 4 will drive the second roller 5 away from the fixed base 1 under the action of the return spring 6, so as to form a placement space for the silver needles between the second roller 5 and the first roller 2. Preferably, the return spring 6 is installed in the movable base 4, is coaxially arranged with the guide rod 3, and has one end connected to the movable base 4 and the other end connected to the guide rod 3.
[0036] In the present utility model, the relatively stable position formed between the second roller 5 and the first roller 2 is achieved through the action of a locking structure. When it is necessary to adjust the relative position between the second roller 5 and the first roller 2, the restriction of the locking structure on the movable base 4 is released, and then the adjustment can be carried out. In this embodiment, the locking structure specifically includes a lateral sliding plate 7, an unlocking block 9, a locking block 11, and a compression spring 12. The lateral sliding plate 7 is arranged along the length direction of the fixed base 1. One end of the lateral sliding plate 7 is fixedly connected to the fixed base 1, and the other end is slidably inserted into a sliding groove 10 opened on the side wall of the movable base 4. A plurality of through holes 8 are opened on the plate surface of the lateral sliding plate 7. The plurality of through holes 8 are arranged at intervals along the sliding direction of the movable base 4. A limiting groove is provided on the pore wall of each through hole 8. The limiting groove includes an axial groove 8.1 and a circumferential groove 8.2. The axial groove 8.1 is arranged along the axial direction of the through hole 8, and one end thereof facing the middle of the movable base 4 is communicated with the circumferential groove 8.2. The circumferential groove 8.2 is perpendicular to the axial groove 8.1. An unlocking block 9 is movably arranged in each through hole 8. One end of the unlocking block 9 is located outside the through hole 8, and the other end is inserted into the through hole 8. A limiting protrusion 9.1 is arranged on the outer wall of the unlocking block 9. The limiting protrusion 9.1 is movably embedded in the limiting groove. When the limiting protrusion 9.1 moves into the circumferential groove 8.2, the end of the unlocking block 9 inserted into the through hole 8 is flush with the end of the through hole 8 facing the middle of the movable base 4. A placement groove is opened on the groove wall of the movable base 4 where the sliding groove 10 is opposite to the through hole 8. One end of the locking block 11 is located in the placement groove and is connected to the compression spring 12 in the placement groove. In the natural state of the compression spring 12, the other end of the locking block 11 is located outside the placement groove and is inserted into the through hole 8 when the placement groove is opposite to a through hole 8.
[0037] That is, in this embodiment, the locking structure realizes locking and unlocking by whether the locking block 11 is inserted into the through hole 8. Specifically, inserting different through holes 8 results in different spacings between the second roller 5 and the first roller 2. In this way, by selecting different through holes 8, the silver needle placement space formed between the movable base 4 and the fixed base 1 can be different. After determining one through hole 8, other through holes 8 are unavailable, and the locking block 11 can only be embedded in the determined through hole 8. In this way, the movable base 4 and the fixed base 1 can only be repeatedly fixed and reset within the determined range of movement, and the silver needles of the same specification can be repaired. When it is necessary to repair the silver needles of another specification, it is necessary to re-determine another through hole 8. Since the unlocking block 9 used on the through hole 8 can slide axially in the through hole 8, after it is abutted by the locking block 11 inserted into the through hole 8, the unlocking block 9 can be pressed to cause the locking block 11 to withdraw from the through hole 8 and cooperate with the resetting action of the resetting spring 6 to achieve unlocking, that is, the operation of limiting the silver needle and releasing the silver needle of the movable base 4 can be completed by a one-press method, which greatly simplifies the operation process. When the locking block 11 passes through the through hole 8, it will not extend into the through hole 8 under the action of the compression spring 12. Only when the locking block 11 passes through the through hole 8 which is not in the axial locking state, can the locking block 11 be embedded in the through hole 8, and the movable base 4 cannot continue to slide. Therefore, by adjusting the state of the unlocking block 9 in each through hole 8, the adjustment and fixation of the silver needle placement space can be achieved.
[0038] Preferably, the end of the locking block 11 outside the placement groove is hemispherical, which is convenient for insertion into the through hole 8 and sliding against the lateral slide plate 7. Preferably, the sliding groove 10 is opened from the end of the movable base 4 toward the fixed base 1, but does not extend to the end of the movable base 4 away from the fixed base 1. Preferably, the lateral slide plate 7 and the guide rod 3 are spaced apart along the width direction of the fixed base 1.
[0039] The needle repairing principle of the utility model is as follows:
[0040] Select the corresponding through-hole according to the specifications of the silver needle to be repaired, so that the limit protrusion 9.1 of the unlocking block 9 of this through-hole falls into the axial groove 8.1, while the limit groove of the unlocking block 9 of other through-holes falls into the circumferential groove 8.2. At this time, the end of the unlocking block 9 of other through-holes is flush with the through-hole, such as Figure 5 the unlocking blocks 9 at the first through-hole, the third through-hole and the fourth through-hole shown close to the fixed base 1. When the movable base 4 is pressed to move it towards the fixed base 1, when the locking block 11 passes through the fourth through-hole, the third through-hole to the second through-hole in sequence, the locking block 11 can push the unlocking block 9 to axially move towards the side away from the middle of the movable base 4. The locking block 11 is inserted into the second through-hole, and the movable base 4 is fixed relative to the fixed base 1 to achieve the locked state. At this time, the silver needle placement space formed between the second roller 5 and the first roller 2 can limit the silver needle to be repaired, and the silver needle to be repaired can reciprocate to realize needle repair. When unlocking is required, press the unlocking block 9 at the second through-hole to prompt the locking block 11 to leave this through-hole. Under the action of the return spring 6, the movable base 4 moves towards the side away from the fixed base 1.
[0041] The above description is a detailed description of the preferred and feasible embodiment of the present invention, but the embodiment is not used to limit the patent application scope of the present invention. Any equivalent changes or modifications completed under the technical spirit prompted by the present invention shall fall within the patent scope covered by the present invention.
