[0037] like Figures 1-4 As shown, the tool holder 4 of the present invention for a straight-line tool magazine 1 includes a tool magazine 1 and several extension suspension arms 2;

[0038] The rear ends of several of the extended suspension arms 2 are detachably mounted on the tool magazine 1;

[0039] The front end of the extended suspension arm 2 is formed with a tool clip suspension hole 3, and a tool handle 4 is suspended and installed in the tool clip suspension hole 3. The tool handle 4 and the tool magazine 1 are separated from each other.

[0040] The upper side of the extended suspension arm 2 is formed with a transverse groove 5. The direction of the front edge of the tool magazine 1 and the direction of the transverse groove 5 are parallel to each other, and the transverse groove 5 is located in front of the tool magazine 1.

[0041] The principle is as follows: An extension suspension arm 2 is set, and a transverse groove 5 is set on the extension suspension arm 2. When the tool holder 4 is picked up or put down in the tool holder suspension hole 3, even if the tool changing operation is wrong, it will not cause damage to the tool magazine 1 and the spindle, because the extension suspension arm 2 will break off along the transverse groove 5, without damaging the tool magazine 1 and the spindle, thus ensuring their service life. In addition, the extension suspension arm 2 wraps around the tool holder 4 through the tool holder suspension hole 3 for picking up and putting down, avoiding the problem of the spindle directly contacting the tool magazine 1 during tool changing, avoiding abnormal noise during tool changing, and ensuring the stability and service life of the machine tool.

[0042] Furthermore, the rear end of the extended suspension arm 2 is detachably mounted on the tool magazine 1 by bolts, enabling rapid assembly of the extended suspension arm 2 on the tool magazine 1.

[0043] Furthermore: the rear end of the extended suspension arm 2 is formed with at least two bolt holes 6, and the bolts pass through the bolt holes 6 to lock the rear end of the extended suspension arm 2 onto the tool magazine 1. The bottom side of the rear end of the extended suspension arm 2 is formed with a weight reduction groove 7, and the weight reduction groove 7 and the bolt holes 6 are staggered. The weight reduction groove 7 can reduce the weight of the extended suspension arm 2 while ensuring its structural strength.

[0044] Furthermore: the tool magazine 1 is formed with a number of protrusions 8, and the number of protrusions 8 are assembled in a one-to-one gap fit in the weight reduction slots 7 of the extension suspension arms 2; the protrusions 8 can match and combine with the weight reduction slots 7 to realize the precise assembly of the extension suspension arms 2 on the tool magazine 1.

[0045] Furthermore, a countersunk groove 9 is formed in the tool holder suspension hole 3, and the tool handle 4 is placed in the tool holder suspension hole 3 through the countersunk groove 9 with a clearance fit; this facilitates the removal and placement of the tool handle 4 in the tool holder suspension hole 3, ensuring the stability of automatic tool changing.

[0046] Furthermore, a thickened cylinder 10 is formed on the bottom side of the front end of the extended suspension arm 2. The thickened cylinder 10 is integrally formed and set on the lower side of the knife clip suspension hole 3; it can effectively strengthen the strength of the knife clip suspension hole 3 and ensure its service life.

[0047] Optionally: the cross-section of the transverse groove 5 is a trapezoidal structure that is wider at the top and narrower at the bottom;

[0048] Optionally, the cross-section of the transverse groove 5 has a "V" shaped structure;

[0049] In the event of a tool change operation error, the extended suspension arm 2 can be quickly disconnected along the transverse groove 5, thereby avoiding damage to the tool magazine 1 and the spindle and reducing maintenance costs when the machine tool fails to change tools.

[0050] Furthermore: a weight-reducing groove 11 is formed on the bottom side of the front end of the extended suspension arm 2, and a horizontal groove 5 is located behind the weight-reducing groove 11. A reinforcing edge 12 is integrally formed in the middle of the weight-reducing groove 11. The setting of the shock-absorbing groove can reduce the weight of the extended suspension arm 2, while the reinforcing edge 12 is used to ensure the strength of the extended suspension arm 2 and ensure its service life.

[0051] Furthermore, the bottom side of the rear end of the extended suspension arm 2 is formed with a stepped edge 13, which is located below the transverse groove 5; it can work with the transverse groove 5 to achieve rapid breakage in case of tool change failure, effectively preventing damage to the tool magazine 1 and the spindle.

[0052] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
