Separate.

The tool connector can be used for the user to insert the tool head, and then the tool head can be pressed against screws, screws and other screws. Please refer to Figures 4 and 7, the user can first move the inner sleeve 30 to the second position, and the elastic member 40 pushes the inner sleeve 30 so that the positioning member 51 abuts forward against the transverse groove 532, so that The transverse groove 532 is buckled with the positioning member 51, so that the inner sleeve 30 is buckled and held in the second position, and the insertion hole 12 is exposed to the outside for the user to insert the tool head 91, as shown in Figure 8. . Subsequently, referring to Figures 5, 7, and 9, the user can rotate the inner sleeve 30 to drive the positioning member 51 to move along the front edge 5321 of the transverse groove 532 toward the longitudinal groove 531. When the positioning member 51 When abutting against the anti-rotation surface 5311 of the longitudinal groove 531, the inner sleeve 30 is blocked by the anti-rotation surface 5311 and stops rotating. Because the positioning member 51 is located in the longitudinal groove 531 at this time, the inner sleeve 30 is affected by the elastic member 40. The elastic force acts to reset to the first position, and then protrude forward and cover the insertion hole 12 and the tool head 91. As shown in Figure 9, the user can directly place the screw or the accommodating space in the inner sleeve 30 Screws 92 such as screws, or move the inner sleeve 30 backwards and then insert the screws 92 into the tool head 91, waiting for the installation operation. Among them, the tool head 91 may be magnetized by the magnetic force of the magnetic member 70. The screw 92 is sucked, and the screw 92 is held at the front end of the tool head 91. When performing the installation operation, please refer to Figure 10. The user can directly operate from the back end of the tool joint to press the screw 92 against the target position, and then drive the tool joint, tool head 91 and screw 92 to rotate, The screw 92 is screw-locked to the target position.

When the user wants to change the tool head, please refer to Figures 5 and 8. The inner sleeve 30 can be moved to the second position first. The positioning member 51 can move from the open end of the longitudinal groove along with the inner sleeve 30. Move in, and then further rotate the inner sleeve 30, the positioning member 51 can be rotated together to move into the transverse groove, and the inner sleeve 30 is fastened by the positioning member 51 of the fastening device and the transverse groove, and the inner sleeve 30 By keeping it in the second position, the insertion hole 12 can be exposed from the inner sleeve 30, which is convenient for the user to replace the tool head 91.

It should be noted that when the user moves the inner sleeve to the second position, the positioning member first enters the circumferential groove through the longitudinal groove, and abuts against the rear end of the circumferential groove, thereby stopping the inner sleeve from moving backward. Then the user further rotates the inner sleeve to move the positioning member from the circumferential groove to the transverse groove. If the user accidentally activates the power tool before moving the positioning member to the transverse groove, the positioning member will be relative to the buckle. The groove rotates quickly. However, as shown in Figure 6, because the distance between the front and rear ends of the circumferential groove 533 is greater than the diameter of the positioning member 51, and the circumferential groove 533 is ring-shaped, the positioning member 51 can rotate in the circumferential groove 533 This prevents the positioning member 51 from hitting the edge of the buckle groove 53 when it rotates quickly, causing the positioning member 51 to be damaged or falling, and to prevent the positioning member 51 from moving out of the buckle groove 53 to the outer peripheral surface of the body 10 and being stuck in the body 10 when the positioning member 51 rotates rapidly. The outer circumference. Furthermore, since the pushing member can be elastically deformed, if the positioning member accidentally moves out of the buckle groove to the outer circumference of the body due to rapid rotation, the pushing member will be pushed by the positioning member and elastically deform outwards, thereby buffering the positioning The impact received when the part hits the edge of the buckle groove further prevents the positioning part from being damaged or falling. Then, when the user rotates the inner sleeve to move the positioning part into the buckle groove from the outer circumference of the body, the pushing part can be pushed inward The elastic return resets the positioning member at the same time to avoid affecting the buckling function.

In this way, the tool connector described in the above embodiment allows the user to insert the tool head, and then surround the tool head with an inner sleeve. When the user inserts screws or screws and other fasteners in the inner sleeve, the inner sleeve The tube can hold the screw member on the front side of the tool head, and wait for the tool head to abut the screw member for screw lock installation, which can reduce the chance of falling due to collision with other objects, and can continue to maintain the screw member during the screw lock installation process This position prevents the screw from skewing or even popping out due to the reaction force during installation, allowing users to quickly install the screw, which is convenient and safe to use.

Secondly, although the abutting portion is clamped between the socket section and the fixing ring, the abutting portion can still rotate relative to the body, so that the outer sleeve can rotate, and the body can be prevented from colliding during rotation during the installation of the screw. Or rub against other surrounding objects, or the user can directly hold the outer sleeve, which further improves the convenience and safety of the tool joint.

Furthermore, the front end edge of the transverse groove extends obliquely forward from the longitudinal groove, so that the positioning member is buckled in the transverse groove. When the elastic member pushes against the inner sleeve, the positioning member will not be affected by the elastic force. Moving to the longitudinal groove can prevent the buckling device from automatically releasing the buckling state. When the user wants to release the buckle, as shown in Figure 7, only need to rotate the inner sleeve, and the positioning piece will abut against the front edge. Sliding into the longitudinal groove, and then moving forward through the longitudinal groove, it has a simple and easy-to-use operation mode when the inner sleeve is unfastened.

In the foregoing embodiment, the fastening device includes a positioning member, a positioning hole, a buckle groove, and a pushing member. In other possible embodiments of the present invention, the positioning member may be integrally formed on the inner sleeve without positioning holes and pushing members. The positioning element can still be buckled with the buckle groove, which has a similar use effect as the above-mentioned embodiment.

In the above-mentioned embodiment, the positioning member, the positioning hole and the pushing member are arranged on the inner sleeve, and the positioning member protrudes from the inner peripheral surface of the inner sleeve, and the buckle groove is arranged on the main body. In other possible implementations of this creation In the example, the positioning member and the pushing member may be arranged in opposite directions, so that the positioning member protrudes from the outer circumferential surface of the inner sleeve, and the buckle groove is provided on the outer sleeve; or, the positioning member, the positioning hole and the pushing member may be changed to It is arranged on the outer sleeve, so that the positioning piece protrudes from the inner peripheral surface of the outer sleeve, and the buckle groove is arranged on the inner sleeve; or, the positioning piece, the positioning hole and the pushing piece may be changed to be arranged on the body so that the positioning piece is convex Extending on the outer peripheral surface of the main body, the buckle groove is provided in the inner sleeve, which is not necessary.

In the above-mentioned embodiment, the pushing member is a C-ring that fits in the slot of the inner sleeve. In other possible embodiments of the present invention, the pushing member may be changed to fit in the slot of the inner sleeve. As long as the helical compression spring or other elastically deformable elements can elastically abut against the positioning member, this creation is not limited to this.

In the above embodiment, the pushing member is a C-ring and is sleeved in the slot of the inner sleeve. In other possible embodiments of the present invention, the pushing member may be a small helical compression spring and is instead accommodated in In the positioning hole, one end of the positioning hole is a closed end for one end of the spiral compression spring to abut, so that the other end of the spiral compression spring can be elastically pushed against the positioning member, and the positioning member protrudes from the inner peripheral surface of the inner sleeve. Nothing is impossible.

In the above embodiment, the abutting portion is clamped between the sleeve section and the fixing ring and can still rotate relative to the body. However, if the abutting portion is tightly fitted, assembled or welded to the body, or even integrally formed with the body If the abutting portion and the body are completely fixed, the fixing ring and the fixing groove can be omitted, which is also a possible specific embodiment.

In the above embodiment, the buckle device is used to buckle the inner sleeve to temporarily hold the inner sleeve in the second position to facilitate the user to install the tool head. However, if the buckle device is omitted, the user can still use The hand presses against the inner sleeve, manually keeps the inner sleeve at the second position, and performs the installation work of the tool head, and obtains the use function similar to the above embodiment.

In the first embodiment of the present creation described above, as shown in Figures 8 to 10, the outer sleeve and the inner sleeve have corresponding first step surfaces 212 and second step surfaces 32. When the inner sleeve 30 is located at the first step surface 212 and the second step surface 32 At one position, the first step surface 212 and the second step surface 32 abut against each other, which can prevent the inner sleeve 30 from moving further forward from the first position and escaping from the slit between the outer sleeve and the body. Please refer to Figures 11 and 12. In the second embodiment of the present creation, the first step surface 212 and the second step surface 32 of the outer sleeve and the inner sleeve can be omitted, and the body forms a third step facing the rear end instead.
