Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the following detailed description of the embodiments of the present utility model will be given with reference to the accompanying drawings, but the described embodiments of the present utility model are some, but not all embodiments of the present utility model.
As shown in fig. 1 to 3, a blind hole cleaning tool includes: round tube 1 and pull rod 2.
Specifically, the lower section of the circular tube 1 is provided with a plurality of claws 11 along a circumferential array, and the lower ends of the claws 11 are provided with hooks 12 protruding outwards.
Specifically, the pull rod 2 is coaxially arranged in the circular tube 1 in a penetrating manner, the inner wall of the claw 11 is in contact with the outer wall of the pull rod 2, the conical disc 21 is arranged at the lower end of the pull rod 2, the conical surface of the conical disc 21 faces upwards, the diameter of the large end of the conical disc 21 is larger than that of the pull rod 2, the upper end of the pull rod 2 protrudes out of the top of the circular tube 1, and when the pull rod 2 is pulled upwards, the conical surface of the conical disc 21 is in sliding contact with the inner wall of the claw 11 and is used for outwards ejecting the claw 11.
When the tool is used, the round tube 1 and the pull rod 2 are inserted into the blind hole together, the lower end of the conical disc 21 is tightly attached to the side wall of the blind hole so as to enable the clamping jaws 11 to be inserted between the cutting scraps and the hole wall, after the bottom of the conical disc 21 is contacted with the bottom of the blind hole, the round tube 1 is kept fixed, the pull rod 2 is pulled upwards, the conical disc 21 is used for pushing the clamping jaws 11 towards the outer side of the round tube 1 at the same time so as to push the cutting scraps towards the clamping jaws 11 at one side of the cutting scraps to loosen the cutting scraps and clamp the cutting scraps above the hook 12, the loosened cutting scraps can be blown out through the air gun, and the cutting scraps can be quickly loosened or taken out from the blind hole through the tool when the round tube 1 is pulled outwards through the hook 12; when the round tube 1 is pulled out, the pull rod 2 is required to be pulled out together, the pull rod 2 can be pulled during specific operation, so that the round tube 1 is pulled out together by utilizing the friction force between the conical disc 21 and the clamping jaw 11, the operation mode is only suitable for cylindrical holes with smooth inner walls, the relative positions of the pull rod 2 and the round tube 1 along the axis are required to be kept fixed when the round tube is used for threaded holes, the clamping jaw 11 is prevented from being further outwards opened in the pulling process, and then the hook 12 is clamped in threads.
Preferably, as shown in fig. 3, the bottom of the conical disk 21 has a back taper configuration to facilitate pushing the chip against the side walls of the blind hole, thereby facilitating insertion of the jaws 11 between the chip and the blind hole side walls.
Preferably, as shown in fig. 1 and 2, the upper end of the pull rod 2 is provided with a disc 22, so that the pull rod 2 can be pushed and pulled in use.
Preferably, as shown in fig. 1 and 2, a cylindrical spring 3 is sleeved outside the pull rod 2 and is located between the upper end of the pull rod 2 and the circular tube 1, the cylindrical spring 3 is in a compressed state and is used for enabling the conical surface of the conical disc 21 to apply an outward thrust to the clamping jaw 11, so that the clamping jaw 11 is automatically opened outwards, when the pull rod 2 is inserted into a blind hole, the bottom of the circular tube 1 needs to be pressed by hands, the conical disc 21 is separated from the clamping jaw 11, at the moment, the cylindrical spring 3 is further compressed, the clamping jaw 11 is inwards folded under the action of self elastic force, when the conical disc 21 is inserted into the bottom of the blind hole, the pull rod 2 is automatically moved outwards under the action of the elastic force of the cylindrical spring 3, and therefore the clamping jaw 11 is automatically opened outwards by the conical disc 21, and the pressure to the clamping jaw 11 is kept at any time by the conical disc 21, so that the operation is simpler and more convenient when a tool is pulled out.
Further preferably, as shown in fig. 2, a threaded connection structure is provided between the upper section of the pull rod 2 and the round tube 1, when the threads between the pull rod 2 and the round tube 1 are connected, the conical disc 21 is separated from the claw 11, the conical spring 3 is further compressed, and the purpose of the structural design is that when the cleaning tool is not used, the claw 11 is in a natural state to avoid the elasticity of the claw 11, the cylindrical spring 3 is a separate part, even if the elasticity is invalid or weakened, the claw 11 can be replaced, and the round tube 1 needs to be replaced integrally at the same time after the elasticity of the claw 11 is invalid, so that the replacement cost is higher.
The foregoing description of the preferred embodiments of the utility model is merely exemplary and is not intended to be exhaustive or limiting of the utility model. It will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the utility model.
