The pedestal 510 includes two positioning holes 516 , and the positioning holes 516 are spaced apart from the base 510 . The clamping seat 520 includes a body 530 and a receiving corner post 540. The receiving corner post 540 defines two limiting slots 542. The two positioning members 550 are respectively disposed in the two positioning holes 516. Each of the positioning members 550 includes a screw hole 554 and a first inclined surface 552. The two traction members 560 are respectively disposed in the two positioning holes 516 , and each of the tube traction members 560 includes a threaded portion 562 and a step portion 564 . By increasing the number of the positioning member 550, the pulling member 560 and the limiting slot 542, the stability of the assembly of the base 510 and the clamping seat 520 can be further enhanced. Other embodiments of the other embodiment are the same as the other embodiment. I will not repeat them here.

According to the above embodiment, it is known to receive the corner post and the angle The design of the nano-hole matching can avoid the rotation of the clamping seat, and the fitting portion and the fitting groove are assembled, the connection between the base and the clamping seat can be locked, and the positioning member can be displaced in the positioning hole by the traction member, which can be changed. The tightness of the base and the clamping seat can effectively avoid looseness between the base and the clamping seat, thereby enhancing the stability of the connection between the base and the clamping seat, which can improve the reaction force between the base and the clamping seat. The load value, thereby extending the service life of the base and the holder and reducing the cost of replacement and maintenance. In addition, the user only needs to transmit through the locking relationship between the threaded portion of the traction member and the screw hole of the positioning member. The movable traction member can precisely adjust the tension of the positioning member and the base and the clamping seat, so the tool holder of the creation has the advantages of easy operation and high adjustment precision.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and anyone skilled in the art can make various changes and refinements without departing from the spirit and scope of the present invention. The scope of protection is subject to the definition of the scope of the patent application attached.
