The groove wall of the sliding groove 5 is further provided with a clamping groove 54, the clamping groove 54 is opposite to the accommodating groove 51, and the clamping groove 54 and the clamping block 52 are matched with each other at one end extending out of the accommodating groove 51.

A pull-back mechanism for pulling the ends of the two clamping blocks 52 extending out of the accommodating grooves 51 into the two accommodating grooves 51 simultaneously is further arranged in the mounting seat 2.

When the tool body 1 needs to be mounted on the mounting base 2, the two clamping blocks 52 are firstly pulled back by the pull-back mechanism to extend out of one ends of the accommodating grooves 51 and are simultaneously pulled into the accommodating grooves 51 respectively; then the sliding block 4 is inserted into the sliding groove 5; then, the pull-back mechanism is released, so that one end of the clamping block 52 extends out of the accommodating groove 51 under the resilience action of the elastic piece 53, and the clamping block passes through the clamping hole 41 and then is inserted into the clamping groove 54, and the tool body 1 is clamped on the mounting seat 2 under the action of the clamping block 52. When the tool body 1 needs to be detached from the mounting seat 2, the end of the clamping block 52 extending out of the accommodating groove 51 is pulled into the accommodating groove 51 through the pull-back mechanism, so that the tool body 1 can be smoothly taken down. By the clamping mode, the cutter body 1 can be installed on the installation seat 2 or detached from the installation seat 2, the cutter body 1 does not need to be installed on the installation seat 2 or detached from the installation seat 2 in a mode of repeatedly screwing or loosening a fastener, and therefore the problems that the cutter replacing efficiency is low and the working efficiency is influenced are solved.

Wherein, for reducing when tool bit 3 processes the work piece, because of the vibration and lead to the probability of the edges and corners wearing and tearing of slider 4 and joint piece 52, all round angle at the edges and corners of slider 4 and joint piece 52 and the position that matches with both.

Referring to fig. 2, a mounting groove 6 and two rope grooves 61 are formed in a mounting seat 2, the mounting groove 6 is formed in one side, away from the direction of a groove opening of a sliding groove 5, of the mounting seat 2, the mounting groove 6 is a T-shaped groove, the section, perpendicular to the opening direction of the mounting groove 6, of the mounting groove 6 is circular, and internal threads are formed in the inner wall, close to the groove opening of the mounting groove 6, of the mounting groove 6; the rope groove 61 is communicated with the mounting groove 6 and the accommodating groove 51, and the two rope grooves 61 are respectively communicated with the two accommodating grooves 51.

Referring to fig. 2, the retracting mechanism includes a fixing rod 62 and two pulling ropes 63, the fixing rod 62 is cylindrical and is formed with external threads, the fixing rod 62 is connected to the inner wall of the mounting groove 6 in a threaded manner, one end of the fixing rod 62 extends out of the notch of the mounting groove 6 and is provided with a handle 621, and the fixing rod 62 moves in the mounting groove 6 along the notch direction of the mounting groove 6 by rotating the handle 621; two stay cords 63 penetrate through the two cord grooves 61 respectively, one end of each stay cord 63 is fixed at one end of the fixing rod 62 close to the bottom of the mounting groove 6, and the other end of each stay cord 63 is fixed at the clamping block 52. When the clamping block 52 is inserted into the clamping groove 54, the distance between the fixed rod 62 and the groove bottom of the mounting groove 6 is larger than the length of the clamping block 52.

When need draw back the mechanism and stretch out the one end of holding tank 51 with two joint pieces 52 in respectively drawing in each holding tank 51 simultaneously, handheld handle 621 rotates dead lever 62, make stay cord 63 twine on dead lever 62, thereby realize stretching out the one end of holding tank 51 with joint piece 52 and draw in holding tank 51, so that insert slider 4 in spout 5 or take out slider 4 from spout 5, realize that cutter body 1 installs smoothly on mount pad 2 or pull down cutter body 1 from mount pad 2.

Wherein, in stretching into the holding tank 51 with the joint piece 52 stretching out the one end of holding tank 51 through the mechanism that draws back, insert slider 4 back in the spout 5, the total power of kick-backing of a plurality of compressed elastic component 53 is less than the frictional force of dead lever 62 threaded connection in mounting groove 6 through two stay cords 63 component force of giving dead lever 62, when leading to joint piece 52 can not be smoothly pushed out by elastic component 53, can pass through handle 621 counter rotation dead lever 62 for stay cord 63 is in lax state, thereby guarantees that elastic component 53 can smoothly push out joint piece 52.

In addition, when the joint piece 52 injects into the draw-in groove 54, the stay cord 63 is in the state of straightening to prevent that in long-term use, the stay cord 63 twines on the elastic component 53, influences the flexible effect of elastic component 53.

The embodiment of the application relates to a principle of implementation of a tool mounting structure of CNC (computer numerical control) equipment is as follows: when the tool body 1 is installed, the handle 621 is held by hand first to rotate the fixing rod 62, so that one end of the clamping block 52 extending out of the accommodating groove 51 is pulled into the accommodating groove 51; then the sliding block 4 is slid into the sliding groove 5; then, the handle 621 is loosened and turned reversely, so that one end of the clamping block 52 extends out of the accommodating groove 51 under the action of the elastic member 53, passes through the clamping hole 41 and is clamped in the clamping groove 54. When the tool body 1 needs to be replaced, the clamping block 52 is pulled into the accommodating groove 51 through the pull-back mechanism, so that the tool body 1 can be taken down from the mounting seat 2.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
