Embodiment Construction

[0017] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Such as figure 1 , 2 As shown, a hand-held reamer includes a positioning shaft 1 that limits the position of the reaming needle 3. The reaming needle 3 is located in the step-shaped limiting hole 1.4, and its bottom end is sleeved at the center of the positioning shaft 1. The mandrel 2 at the position is in contact with each other, and both ends of the mandrel 2 are located outside the positioning shaft 1, one end of which is fixed with the positioning shaft 1 by a fixing nut 4, and the other end is connected with a rotating handle 6, by turning the rotating handle 6 The mandrel 2 is rotated in the shaft hole 1.2, so that the reaming needle 3 located in the limiting hole 1.4 performs telescopic movement.

[0019] Such as image 3 As shown, the positioning shaft 1 includes a positioning shaft body 1.1, a shaft hole 1.2 is opened at th...

Abstract

The invention provides a handheld reamer. The handheld reamer comprises a positioning shaft used for limiting a reaming needle, wherein the positioning shaft comprises a positioning shaft body, a shaft hole is formed in the axis of the positioning shaft body, and a limiting hole which is perpendicular to the shaft hole and communicates with the shaft hole is formed in the positioning shaft body; amandrel is sleeved with the shaft hole, and a notch is formed in the outer wall of the mandrel; and the two ends of the mandrel are both located outside the positioning shaft, one end of the mandrelis fixed to the positioning shaft through a fixing nut, and the other end of the mandrel is connected with a rotating handle. The rotating handle is rotated to enable the mandrel to rotate in the shaft hole, and therefore the reaming needle located in the limiting hole can perform telescopic movement. The handheld reamer is simple in structure, people can adopt the reaming needle to carry out reaming on a metal tube, the reaming needle can be well protected, and the reaming needle is contracted in the space formed by the notch and the limiting hole when not used, and is extended out of the limiting hole for reaming when used.

Description

technical field [0001] The invention relates to a hole reamer, in particular to a hand-held reamer. Background technique [0002] A large number of metal pipes are installed on passenger cars and other vehicles. Different metal pipes are connected in different ways, some are connected by bolts, and some are socketed by large pipes and small pipes. Wherein, when a large pipe covers a small pipe, the port of the pipe needs to be enlarged to facilitate the pipe socket. In addition, there are still many pipe ends that need to be installed with some parts, and the diameter of the pipes also needs to be enlarged to facilitate installation. Since the reaming needle is relatively small and inconvenient to operate manually, it is necessary to design a tooling that is convenient for reaming metal pipes, which can improve the connection and installation of the pipe ends and improve production efficiency, which has certain significance for the production of passenger cars and the like....
