The body preferably further includes a tool end 16 which is provided, for example, with a power tool (such as the pneumatic tool of FIG. 6 and the power tool of FIG. 8) and the extension rod ( The tool joint can also be integrally connected with a handle (as shown in Fig. 7), such as a screwdriver head post, a sleeve or the like. The elastic pushing mechanism is disposed in the inner hole, and the spring top is inserted into the connector 100 of the inner hole by the socket. The latching mechanism 30 includes a pin portion 31 and a latching portion 32. The pin portion is slidably inserted through the sliding hole and axially interlocked with the elastic pushing mechanism. The latching portion is received in the inclined hole and The inner hole may be partially protruded radially, and the latch portion 32 is interlocked with the pin portion 31 and the elastic pushing mechanism 20. Thereby, the latching mechanism can effectively lock or release the connector (such as a tool head, an extension rod, or the like) and quickly replace the connector, and the structure is simple and convenient to use.

In detail, the elastic pushing mechanism 20 includes a push rod 21 and at least one elastic member abutting between the push rod and the barrel portion. The push rod 21 includes a pusher head 22 and a shaft 23 connected to the pusher head. The inner hole includes a large diameter section 121 and a small diameter section 122 connected to each other, and a large diameter section and the small diameter A shoulder 123 between the segments, the large diameter segment is connected to the socket, and the shaft is slidably inserted into the small diameter segment. Preferably, the pusher is mounted (e.g., embedded) with a magnetic member 24 for magnetically absorbing the connector to prevent the connector from falling out.

Specifically, the large diameter segment includes a non-circular hole segment 124 for externally engaging the connector. For example, the connector is a tool head having a hexagonal body, the non-circular hole segment is a hexagonal hole, and the pusher is six An angled and slidable portion of the large diameter portion, the shaft includes a large diameter portion 231 connecting the push head and a small diameter portion 232 connecting the large diameter portion, the push head having a larger diameter than the large diameter portion and opposite The large diameter portion defines a blocking shoulder 221, and the small diameter portion includes a resisting surface 125 away from the large diameter portion. The number of the at least one elastic member is two, and one of the elastic members 25 abuts against the pushing head. Between the shoulder and the shoulder, the other elastic member 26 abuts between the pin portion and the abutting surface. Wherein, since the latch portion is interlocked with the pin portion and the elastic pushing mechanism, only the elastic member 26 is required to effectively lock or release the connector.

In this embodiment, the push rod is provided with an axially extending slot 27, the pin portion is slidably inserted into the slot, wherein the slot extends through the large diameter portion and the small diameter portion on. The tubular section further has a straight groove 17 communicating with the inclined hole on the outer surface, and the latching mechanism further comprises a straight section 33 connected between the pin part and the latching portion, the straight section Place in this straight slot. The sleeve is further provided with a notch 34 communicating with the straight groove on the outer surface, the slot bottom is provided with the sliding hole, and the latching mechanism further comprises a latching member 35 and a pin member 36, the card The latching member is provided with the latching portion and a receptacle 37 located in the slot, and the pin member passes through the jack and the sliding hole to be inserted into the slot of the elastic pushing mechanism. In this embodiment, the latching member is an integrally formed metal wire member, and the latching portion is bent at right angles into a straight arm, and the insertion hole is formed by winding one end of the metal wire member. Thereby, the latch member can be directly and accurately moved without axial deformation during actuation, so that the engagement or release of the connector is extremely accurate and stable.

Preferably, the quick release post further includes a ring member 40 that slides on the body, a sleeve 50 that is sleeved on the body and is fastened to the ring member, and a sleeve 60. The ring member is pierced by the pin member and covers the notch. The pin member 36 passes through two sides of the elastic pushing mechanism, and the sleeve blocks the two ends of the pin member to limit and protect the pin member. The sleeve 60 is sleeved and fixed to the barrel section and covers the latching mechanism and a portion of the ring member, thereby limiting and protecting the latching mechanism.

In actual operation, when the connector 100 is inserted by the socket 13, the latch portion 32 of the latch member 35 is firstly retracted, and the pin member 36 is slightly moved back in the slot 27 (the ring member is radially displaced). Corresponding to the pin member, a space for the axial movement of the pin member (such as a ring groove) may be additionally provided, so that the card member is relatively easy to resist, and the ring member is not required to be repelled at the same time, to the connector. When the one of the latching holes 101 is aligned with the inclined hole 14, the elastic member 26 pushes the pin member 36 forward to drive the latching member to cause the latching portion to normally abut against the latching recess 101, so that the connector is automatically Locking and not detaching; when the connector is to be removed, when the ring member 40 is axially moved back to the middle of the slot 27, the latch portion 32 is disengaged from the latching recess 101, at which time the slot 27 is The segment still allows the push rod to be moved forward by a distance relative to the pin member 36. Therefore, the elastic member 25 pushes the push rod 21 forward, and the connector member 100 can be automatically ejected, so that the user can perform the joint with one hand. It is convenient to replace, save time and work efficiently. In addition, the ring member or the like is configured to drive the member of the latching mechanism to be disposed at the rear end, the body has a smaller diameter and can extend into the narrow hole, and in the rotating operation, the member such as the ring member is located outside the hole. It will not be damaged by hitting the hole wall, and will not be forced to move, so that the connector will come out and hurt the person (as shown in Figure 8).
