The present invention relates to a tool magazine tool handle holding device, in particular to a tool magazine tool handle holding device which is easy to manually advance and retract the tool handle.

Generally speaking, the tool magazine is used to store a plurality of tool handles or tool bars, and the tool handles or tool bars are used to insert tools respectively. The processing machine takes the required tool handles from the tool magazine and moves them to the processing place. to be processed.

In order to stably carry the tool and withstand the force of processing, the handle is usually made of very strong material and has a considerable weight. When it is stored in the tool magazine, it must be positioned with a positioning method with sufficient strength to prevent the handle from loosening. and fall.

The most common positioning method is to set an accommodating hole on the side wall of the knife sleeve, and set an elastic member and a positioning steel ball in the accommodating hole, so that the positioning steel ball stops at the rear end of the ball head of the knife handle, so as to prevent the knife handle from moving outward. The knife handle is very heavy, and the elastic part must have a very large elastic force to prevent the knife handle from easily overcoming the elastic force of the elastic part and coming out. Because of this, when the knife handle is to be taken out or inserted into the knife handle, it must be pushed with a large mechanical force. The handle of the knife can overcome the elastic force of the elastic member and make the positioning steel ball retract inward.

Patent TW M606496 discloses a similar structure, in which the elastic element is arranged horizontally to spring a sliding sleeve, and the sliding sleeve is provided with a space for the steel ball to withdraw, and the elastic force of the elastic element is used to make the space for the steel ball to withdraw and the steel ball to be staggered. , in order to keep the steel ball protruding toward the knife handle; when the knife handle is to be taken out or the knife handle is to be inserted into the knife sleeve, the claw hook outside the sliding sleeve is used to overcome the elastic force of the elastic piece, so that the space where the steel ball retreats is moved to the steel ball, and the steel ball is was able to retract, allowing the handle to enter and exit freely.

However, in the above structure, in order to properly position the heavy knife handle, the elastic member also needs to be selected with a large elastic force. Therefore, the power requirement for connecting the hook is still large, and manual operation cannot be performed. In addition, the component structure is extremely complicated, in addition to increasing the cost , but also increase the probability of failure.
