Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a knitting needle tip grinding device. Background Art

[0002] When making textile needles, a needle tip grinder is needed. The needle tip grinder can grind the relatively small metal workpiece part such as the textile needle tip, so that the size of the textile needle tip meets the actual production needs, and at the same time remove the burrs and oxide layer on the needle tip to ensure the quality of the textile needle.

[0003] When the needle tip grinder is actually used, the needle tip is grinded by two large grinding wheels and a small auxiliary grinding wheel. However, one of the grinding wheels close to the edge has no cover on the outside. If the operator accidentally touches the outer surface of the grinding wheel, it is easy to be scratched by the grinding wheel, which poses a certain safety hazard. Utility Model Content

[0016] The effect achieved by the above components is: by providing a rubber sleeve with a groove and arranging the rubber sleeve on the outer surface of the handle, the friction of the outer surface of the handle can be increased, so that it has an anti-slip effect when holding the handle. At the same time, the rubber sleeve is detachable, which makes it easy to maintain and replace the rubber sleeve.

[0017] Preferably, a clamping strip is fixedly connected to the inner wall of the rubber sleeve, a clamping groove is provided on the outer surface of the handle, and the outer surface of the clamping strip is inserted into the inner wall of the clamping groove.

[0018] The effect achieved by the above components is that the rubber sleeve can be limited by providing the clamping block and the clamping groove, which is beneficial for the rubber sleeve to rotate when the handle is held.

[0019] Preferably, a sleeve is sleeved on one end of the handle, a bolt is inserted into the inner wall of the sleeve, and the outer surface of the bolt is threadedly inserted into the inner wall of the handle.

[0020] The effect achieved by the above components is: by setting a sleeve, the sleeve is sleeved on one end of the handle so that one side of the sleeve abuts against one end of the rubber sleeve, and then the bolt is inserted into the inner wall of the sleeve, and the bolt is rotated so that the bolt enters the inner wall of the handle, the sleeve can be fixed, and then the rubber sleeve can be fixed.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, by setting a protective plate, under the action of the threaded rod, the threaded rod can drive the protective plate connected to the extension block to move synchronously until the protective plate blocks the top of one of the first grinding wheels. This helps prevent the operator from accidentally touching the outer surface of the grinding wheel and being scratched by the grinding wheel, thereby improving the safety performance of the grinding device.
