The structural features of the present invention and the intended effects thereof will be described below by way of a preferred embodiment, but are not intended to limit the scope of the present invention.

Referring to FIG. 1 to FIG. 4, a preferred embodiment of the present invention is shown. A pipe expander 1 of the present invention comprises a pinch tube assembly 10, a pipe expanding mechanism 20 and a latching mechanism 30.

The pinch tube assembly 10 can be provided with at least one clamping hole 11 . For example, in the embodiment, the pinch tube assembly 10 can have a length direction 12 , and the pinch tube assembly 10 can include a plurality of The clamping holes 11 are arranged in the longitudinal direction 12, and each of the clamping holes 11 is for holding a pipe member 13.

The expansion mechanism 20 can include a set of holes 21 and a reaming head 22, the sleeve hole 21 movably sleeved the pinch tube assembly 10, and the reaming head 22 can face the pinch tube along an axial direction Component 10, the clamping hole 11 is moved. For example, the reaming head 22 can be driven to rotate through the clamping hole 11 by a driving tool 40. The reaming head 22 can be clamped to the hole. The pipe member 13 that sandwiches the hole 11 performs the operation of expanding the pipe. The expansion mechanism 20 can have two arm portions 23 which are disposed at intervals. The sleeve holes 21 can be formed between the two arm portions 23, and one of the arm portions 23 can be provided with an assembly hole 24, and the assembly hole 24 is It is in communication with the sleeve hole 21.

The latching mechanism 30 is disposed on the tubing mechanism 20, and the latching mechanism 30 is linearly movable in a direction transverse to the axial direction and is engaged with the clip assembly 10, and the latching mechanism 30 is, for example, usable. The pusher is pushed into the sleeve hole 21 and abuts against the pinch tube assembly 10 to produce a latching function. For example, the latching mechanism 30 can include, for example, a pressing member 31, the pressing member 31. Sliding on the assembly hole 24, one end of the pressing member 31 is for pushing and driving the other end to slide into the sleeve hole 21 and the clamping tube assembly 10 is clamped, so that the locking mechanism 30 can be fastened. The effect.

Further, the pressing member 31 is cylindrical and has a large diameter section 311 and a small diameter section 312, and the end of the small diameter section 312 is tapered to form a tapered shape, and the small diameter section 312 is formed. The latching mechanism 30 further includes a pivoting member 32. The latching member 32 has a pivot 33 and is pivotally connected to the expanding mechanism 20 along the pivoting shaft 33. The direction of the pivot 33 is parallel to the longitudinal direction 12, and the trigger member 32 extends laterally from the pivot 33 to form a cam segment 34. The cam segment 34 is dimensioned in a direction around the pivot 33. The outer end of the large diameter end 311 is flat and abuts against the cam segment 34. The trigger member 32 includes a handle 35 disposed at the other end opposite to the cam segment 34.

The pressing member 31 is selectively movable between a release position P1 and a click position P2. When the pressing member 31 is located at the release position P1, the pressing member 31 and the pinch assembly 10 is separated from each other, and when the pressing member 31 is located at the latching position P2, the pressing member 31 is engaged with the pinch tube assembly 10. Furthermore, one side of the pinch tube assembly 10 can be provided with a plurality of fixing recesses 14 around which the user can pull the handle 35 in a pushing direction 50 to drive the cam segments. Rotating around the pivot 33 and pushing against the pressing member 31 to move toward the latching position P2, so that the end of the small diameter section 312 can selectively abut against one of the fixing recesses 14 to achieve rapid positioning. efficacy.

The latching mechanism 30 can further include an elastic member 36 that is elastically supported between the expanding mechanism 20 and the pressing member 31. The elastic member 36 can have elastic energy to enable the pressing. The member 31 has a tendency to move toward the release position P1. Further, the elastic member 36, the pressing member 31 and the trigger member 32 are sequentially assembled to the assembly hole 24, and the elastic member The 36-seismic spring is disposed between the inner wall of the assembly hole 24 and the large diameter section 311, and the small diameter section 312 penetrates the elastic member 36, more specifically, when the user is in the opposite direction of the thrust direction 50. When the handle portion 35 is pulled, the elastic member 36 is pushed against the pressing member 31 to move toward the release position P1, so that the pinch tube assembly 10 can slide in the sleeve hole 21 to adjust the pinch tube assembly 10 position.

It is worth mentioning that by using the pulling member 32, the pinch tube assembly 10 can be quickly fixed, and the pinch tube assembly 10 can be quickly released, which is convenient for the user to use and reduce Work hours and increase efficiency. The peripheral wall of the assembly hole 24 can be further provided with a pin member 25, and the pin member 25 is disposed along the pivot shaft 33 so that the trigger member 32 can pivot about the pin member 25. The peripheral wall of the assembly hole 24 can be formed with a slot 26 that communicates with the assembly hole 24 such that at least a portion of the trigger member 32 can be received in the slot 26. In addition, the handle portion 35 may have an arc shape corresponding to one side edge 27 of the pipe expanding mechanism 20, and the side edge 27 is connected to the peripheral wall of the assembly hole 24 and faces away from the assembly hole. Direction dimension of 24 The handle portion 35 can be disposed to be folded inwardly, so that the handle portion 35 can be placed in contact with the side edge 27 to facilitate storage and space saving.
