Description

TECHNICAL FIELD

[0001] The utility model relates to a hand-held fixator for polishing a bead of a cultural trinket. BACKGROUND

[0002] When a cultural trinket is made into a real object, polishing tools are often used to polish, shape and polish the cultural trinket to remove surface impurities, so that the surface of the cultural trinket is neat, delicate and smooth.

[0003] In the traditional polishing process, there are two polishing methods. One is to rotate a bead holder controlled by a motor, and the cultural trinket is held by hand to polish the bead holder. In this method, the hand is easy to touch the edge of the bead holder and damage the skin, and the safety is poor. The other is to rotate the cultural trinket controlled by a motor, and the bead holder is held by hand to polish the cultural trinket. In this method, the cultural trinket is installed on a fixed needle, and the cultural trinket rotates with the fixed needle when the fixed needle rotates controlled by the motor. If the fixed needle penetrates the cultural trinket, only the two sides of the cultural trinket can be polished, and the cultural trinket cannot be fully polished and cannot be a perfect circle. If the fixed needle does not penetrate the cultural trinket, the fixed needle rotates in the cultural trinket and easily cracks the cultural trinket.

[0039] Figure 1 A structure schematic view of a ball polishing handheld fixator according to an embodiment of the present application is shown in the figure, Figure 2 A structure schematic view of a first handle according to an embodiment of the present application is shown in the figure, Figure 3 A sectional view of a second handle according to an embodiment of the present application is shown in the figure, as shown in title 1-3, a ball polishing handheld fixator of the present application comprises:

[0040] The first handle 10, the second handle 20 and the fixing needle 30;

[0041] The first handle 10 axially extends into the second handle 20, and the second handle 20 is freely mounted on the extending part of the first handle 10, so that the second handle 20 can axially move relative to the first handle 10;

[0042] The fixing needle 30 axially penetrates the second handle 20 from the outside and extends into the first handle 10, one end of the fixing needle 30 is exposed from the second handle 20, and the exposed end of the fixing needle 30 is used to assemble the ball 40, and the ball 40 is assembled on the fixing needle 30 in a rotatable manner;

[0043] When the ball 40 is assembled on the fixing needle 30, the second handle 20 is axially moved relative to the first handle 10 to change the extending length of the fixing needle 30, so that the ball 40 abuts against the end of the second handle 20 and the end of the fixing needle 30 is flush with the surface of the ball 40.

[0044] Specifically, the first handle 10, the second handle 20 and the fixing needle 30 are coaxially arranged, when the fixing needle 30 is inserted into the first handle 10, the fixing needle 30 is fixed by the first handle 10, and when the second handle 20 is assembled with the first handle 10, the fixing needle 30 can extend from one end of the second handle 20, and the length of the fixing needle 30 extending out of the second handle 20 can be adjusted by controlling the axial movement of the second handle 20 relative to the first handle 10;

[0045] When the handheld fixing device is used, the ball 40 is sleeved on the fixing needle 30, and the ball 40 abuts against the end of the second handle 20, and in order to polish the ball 40 more comprehensively, it is necessary to ensure that the end of the fixing needle 30 is flush with the outer surface of the ball 40 after penetrating the ball 40, so when the ball 40 of different diameters is installed, the second handle 20 can be axially moved to increase or decrease the length of the fixing needle 30 extending out of the second handle 20, until the ball 40 abuts against the end of the second handle 20 and the end of the fixing needle 30 is flush with the surface of the ball 40, and then when the ball 40 is polished with the ball polishing device, the fixing needle 30 does not affect the polishing area of the ball 40, so that the polished ball 40 is more regular and beautiful, and the handheld fixing device is used to polish the ball 40 instead of holding the ball 40 by hand, which greatly reduces the labor intensity of the workers, and by adjusting the axial extending length of the fixing needle 30 to match the ball 40 of different diameters, the situation that various tree seeds are of different sizes can be solved, and the use range is wide.

[0046] Further, the ball 40 is a trinket, a plurality of balls 40 are polished and then connected one by one to form a bracelet for people to wear, and in the scheme of the utility model, the ball 40 can be a wooden ball, a jade, a peach pit, a soapberry and various round seed materials.

[0047] Further, as shown in Figure 2 The first handle 10 comprises a first hand grip 101, a first connecting part 102, a second connecting part 103 and a clamping part 104 arranged axially;

[0048] The first hand grip 101, the first connecting part 102 and the second connecting part 103 are fixedly connected in sequence, the second connecting part 103 extends into the clamping part 104, and the clamping part 104 is axially movable relative to the second connecting part 103;

[0049] The fixing needle 30 extends into the first hand grip 101 through the clamping part 104, the second connecting part 103 and the first connecting part 102 in sequence, and the fixing needle 30 is movably connected with the first handle 10;

[0050] When the clamping part 104 moves axially relative to the second connecting part 103, the clamping part 104 is used to loosen or clamp the fixing needle 30.

[0051] Specifically, the first connecting part 102 is used to connect with the second handle 20, and the two can be arranged as threaded connection, the outer thread is arranged on the side wall of the first connecting part 102, and the inner thread is arranged in the second handle 20, so that the two are connected, the second handle 20 can move axially relative to the first connecting part 102 by rotating the second handle 20, and then the length of the part of the fixing needle 30 extending out of the second handle 20 is realized.

[0052] And, since the second handle 20 is threaded connected with the first connecting part 102, the length of the fixing needle 30 extending out can be fine-tuned, the installation of the ball 40 is more accurate, and the wear of the fixing needle 30 is reduced.

[0053] Further, the first hand grip 101 is used for the operator to hold, and the outer side wall is arranged as arc-shaped, which is more ergonomic and more comfortable to use.

[0054] Further, the second connecting part 103 is used to connect with the clamping part 104, and the two can also be arranged as threaded connection, the outer thread is arranged on the outer wall of the second connecting part 103, and the inner thread is arranged in the clamping part 104, so that the two are connected, and the clamping part 104 is arranged as a three-jaw chuck, and three clamping jaws 1041 are uniformly distributed along the axial line in the clamping part 104, when the clamping part 104 moves axially relative to the second connecting part 103, the three clamping jaws 1041 move close to or away from each other, and the clamping and loosening of the fixing needle 30 are realized.

[0055] In this way, the fixed needle 30 is movably connected with the first handle 10, so that the fixed needle 30 can be replaced. With long-term use of the handheld fixer, the end of the fixed needle 30 will be gradually worn out, and the overall length will gradually decrease. At this time, the clamping piece 104 needs to be loosened from the fixed needle 30, and the fixed needle 30 needs to be extracted by a certain length to achieve normal use. At the same time, when polishing different diameters of the ball 40, the diameter of the perforation in the ball 40 for the fixed needle 30 to pass through will also be different. At this time, the fixed needle 30 of different diameters needs to be replaced to complete the installation of the ball 40.

[0056] Further, as shown in Figure 3 The second handle 20 is provided with an axial first through hole 201 and a second through hole 202. The first through hole 201 communicates with the second through hole 202. The diameter of the first through hole 201 is equal to the diameter of the first connecting part 102. The diameter of the second through hole 202 is equal to the diameter of the fixed needle 30.

[0057] The first through hole 201 is used for the insertion of the first connecting part 102, and the second through hole 202 is used for the passage of the fixed needle 30.

[0058] Specifically, an internal thread is arranged on the inner wall of the first through hole 201, which is matched and connected with the external thread of the first connecting part 102, so as to realize the installation of the second handle 20 and the first handle 10.

[0059] A first tapered structure 203 is arranged at one end of the second handle 20. The diameter of the first tapered structure 203 gradually decreases away from the second handle 20. The second through hole 202 penetrates the first tapered structure 203 along the axis of the second handle 20.

[0060] By arranging the first tapered structure 203, the diameter of the end of the second handle 20 is reduced, so that when the handheld fixer is close to the ball polishing device for polishing the ball 40, the handheld fixer can be inclined at a larger angle relative to the ball polishing device, and more surfaces of the ball 40 can be polished, so that the shape of the ball 40 can be easily controlled. When the end of the second handle 20 is arranged at a right angle, the handheld fixer cannot be inclined at a larger angle relative to the ball polishing device, and more surfaces of the ball 40 cannot be polished.

[0061] Further, a second tapered structure 204 is arranged in the tail of the second through hole 202. The second tapered structure 204 communicates with the first through hole 201 and the second through hole 202 at both ends.

[0062] The diameter of the second tapered structure 204 gradually decreases away from the first through hole 201. The minimum diameter of the second tapered structure 204 is equal to the diameter of the second through hole 202. The second tapered structure 204 is used to guide the fixed needle 30 into the second through hole 202.

[0063] Specifically, during installation, the fixing needle 30 is first inserted into the first handle 10, clamped by the clamping piece 104, the second handle 20 is sleeved on the first handle 10, and the second handle 20 is rotated relative to the first handle 10, so that the second handle 20 continuously approaches the first handle 10;

[0064] With the continuous approach of the second handle 20 to the first handle 10, the fixing needle 30 in the first through hole 201 continuously approaches the second through hole 202, since the fixing needle 30 and the second through hole 202 are equal in diameter and are on the same axis line, the end of the fixing needle 30 deviates from the axis line by a certain distance due to gravity or installation error, so that the fixing needle 30 cannot be easily inserted into the second through hole 202 and extended from the second handle 20;

[0065] In order to solve the problem, the second taper structure 204 is provided, which gradually decreases in diameter away from the second handle 20, and the minimum diameter is equal to the diameter of the second through hole 202, so that the inner wall of the second taper structure 204 becomes a slope, when the end of the fixing needle 30 deviates from the axis line, the end will touch the inner wall of the second taper structure 204, and then be limited and guided by the slope, until the fixing needle 30 is inserted into the second through hole 202, facilitating installation.

[0066] Further, in another embodiment of the utility model, a screw (not shown in the figure) is arranged axially in the first taper structure 203, the second through hole 202 penetrates the screw along the axis line, and the screw is threadedly connected with the first taper structure 203.

[0067] Since the fixing needle 30 of the device can be detachably connected and can be replaced according to the diameter of the hole in the ball 40, if the second through hole 202 is directly arranged on the first taper structure 203, the entire second handle 20 needs to be replaced when the fixing needle 30 of different diameters is replaced, so that multiple second handles 20 with different diameters of the second through hole 202 need to be prepared, and the overall manufacturing cost is high, therefore, by arranging the detachable screw, the second through hole 202 is arranged in the screw, when the fixing needle 30 is replaced, the screw is disassembled, and the screw with the same diameter of the second through hole 202 is replaced at the same time, which can greatly reduce the manufacturing cost.

[0068] Further, since the ball 40 and the fixed needle 30 are movably connected, the ball 40 can rotate relative to the fixed needle 30, and after the first handle 10, the second handle 20, the fixed needle 30 and the ball 40 are all installed, the ball 40 is polished, the operator needs to control the handheld fixer to be inclined, so that the axis line of the handheld fixer and the axis line of the ball polisher form a certain angle, and the ball 40 is controlled to be clamped on the ball polisher, and when the ball polisher rotates, since the two are not on the same axis line, the rotation speed of the ball 40 and the ball polisher is inconsistent through the decomposition of force, so that the ball 40 can be polished.

[0069] In this way, the ball 40 is polished, and the operator does not need to hold the ball 40 or the ball polisher to abut against each other to polish, so that the hand muscle fatigue of the operator is effectively relieved, the counter shock force during polishing is reduced, the use burden of the operator is reduced, and the ball 40 can rotate around the fixed needle 30 during polishing, so that the roundness and concentricity of the polished ball 40 can be effectively guaranteed.

[0070] In summary, through the scheme of the present application, the ball 40 is polished by using the handheld fixer, the muscle fatigue of the operator and the poor safety problem when the ball 40 or the ball polisher is held by the operator to abut against each other to polish in the prior art are solved, the length of the ball 40 installed by the fixed needle 30 can be adjusted by the axial movement of the second handle 20, the fixed needle 30 can be disassembled from the first handle 10 to replace different diameters, the polishing of the ball 40 with different diameters is realized, and the use range of the handheld fixer is increased.

[0071] The above description is only the preferred embodiment of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the technical range involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by the above technical features or equivalent features in any combination without departing from the technical concept. For example, the above features are replaced with the technical features disclosed in the present application (but not limited to) having similar functions to form a technical solution.
