Tool engagement device

The invention relates to a meshing device for a tool, in particular to a design for providing a user to adjust the working head to an appropriate angle for operation.

Wrench tools are widely used to lock and unscrew fasteners to assemble or disassemble components of various industries. The finished products of various industries range from household appliances to precision instruments. Therefore, the process of operating the wrench tool is limited by the position and space of the operation, resulting in the user not being able to operate the wrench tool properly and providing appropriate torsion force. Lock or loosen the screw.

In order to overcome the limitation of space and increase the convenience of the user's force, the related art has improved the conventional integrally formed wrench tool into a structure in which the working head can adjust the angle with respect to the grip. Please refer to the "Wrench Swing Head Control Structure" of the Republic of China Patent Publication No. M376389, which includes a tool head, a handle and an adjustment mechanism, wherein: one end of the tool head is provided with a driving portion for driving, The other end is provided with a fitting head, and one end of the handle is provided with a first pivoting lug and a second pivoting lug. The inserting clip is interposed between the first pivoting arm and the second pivoting lug, and is first The pivoting arm and the second pivoting arm are pivotally coupled; the adjusting mechanism includes a receiving hole formed on the handle between the first pivoting arm and the second pivoting ear toward the tool head, and a vertical communicating with the receiving hole An insertion hole penetrating from a side end of the handle, an engaging member disposed in the receiving hole, and an adjusting member disposed in the insertion hole, wherein the receiving hole is provided with a pair of ends respectively and the engaging member and the receiving portion The inner part of the hole is elastically biased, and the inner side of the hole is provided with an elastic member which is respectively elastically abutted against the inner side of the adjusting member and the through hole, and the adjusting member is radially provided with a concave surface facing the receiving hole and abutting Face, the abutting surface is for pushing the engaging member to engage with the insert to prevent the tool head from rotating relative to the grip, and concave The face is for the end of the engaging member to be retracted, so that the engaging member and the insert When disengaged, the tool head is free to rotate relative to the grip; the elastic system pushes against the engaging member to urge against the insert.

However, the "wrench head control structure" of the prior art overcomes the space limitation, so that the insert can be positioned relative to the grip adjustment angle. However, the prior art is a multi-tooth meshing type to fix the angle of the insert, so it is necessary to have a high-precision tooth portion to achieve stable engagement between the tooth portion and the tooth portion of the insert head, otherwise it is also fixed. The gap is created to cause instability in a fixed state. In this way, there is a high processing cost and a lack of time. In addition, when the wrench is operated, the toothing of the engaging member and the insert head may be subjected to a large force by the torque of the actuating force and the direction of the user's operation of the wrench, thereby causing the tooth portion to be used for a long time. Wear. If the engaging surfaces on both sides of the engaging member are worn by the force, the engaging state and the insert engage each other, the meshing state thereof is unstable, and the teeth are concentratedly engaged between the two sides, thereby accelerating the wear.

Therefore, it is necessary to develop a meshing device for the tool which reduces the wear of the tooth and enables the insert and the engaging member to be stably fixed, and the manufacturing cost is low.

The initial state of the cassette group 2 and the actuator head 3 is such that the top mast 22 is engaged with the ratchet block 311 of the actuator head 3.

1. Pressing the adjusting lever 21 to pivot the operating head 3 relative to the gripping rod 1. At this time, the ratchet block 311 of the operating head 3 urges the end of the top mast 22 into the recess 211, and the regulating lever 21 compresses the horizontal The elastic member 23.

2. After the moving head 3 is pivoted to the appropriate angle with respect to the gripping rod 1, the pressing of the adjusting rod 21 is released, and the horizontal elastic member 23 is elastically pushed against the adjusting rod 21 to reset, and the occlusal head portion of the top mast 22 is engaged. 221 is again engaged with the ratchet block 311 of the actuator head 3, and when the occlusal head section 221 of the top mast 22 and the plurality of ratchet blocks 311 are in the engaged state, any of the ratchet blocks 311 are received in the slots 223, and The first abutting surface 312 and the left latching surface 224 of the adjacent ratchet block 311 abut each other, and the second abutting surface 313 and the right latching surface 225 of the other adjacent ratchet block 311 abut each other. Therefore, the actuator 3 is angularly positioned with respect to the grip 1 and the top mast 22 and the ratchet block 311 are brought into stable engagement.

The advantage is that when the left latching surface 224 and the right latching surface 225 are closely abutted against the first abutting surface 312 and the second abutting surface 313, the ratchet block 311 is subjected to the operation of the operating tool. The force is used to reduce the wear of the ratchet block 311, so that the operating head 3 is angularly stable relative to the gripping rod 1.

In addition, the invention can achieve a high-stability fixed position by a low-precision processing process.

1. The area of the left latch face 224 is larger than the area of each first abutment surface 312, and the area of the right latch face 225 is larger than the area of each second abutment surface 313, thereby reducing the bite head section of the top mast 22 221 The precision of the production process.

2. The accommodating groove 13 includes a regulating groove 131 adjacent to the outer side and a sliding groove 132 communicating with the regulating groove 131. The longitudinal section of the regulating groove 131 is larger than the longitudinal section of the sliding groove 132, and the regulating rod 21 has a head. The end portion 213 and the shaft end 213 are disposed opposite to the head end 213. The front end portion 213 is slightly convex outside the adjusting groove 131. The groove 211 and the step surface 212 are located on the shaft 214, and the shaft 214 of the adjusting rod 21 is located. In the sliding groove 132, the head end 213 of the adjusting rod 21 is limited to the adjusting groove 131. The horizontal elastic member 23 is sleeved on the shaft 214, and the two ends of the horizontal elastic member 23 respectively abut the bottom of the adjusting groove 131 and regulate The head end 213 of the rod 21.

When the adjusting rod 21 is pressed, the head end 213 of the adjusting rod 21 is limited to the adjusting groove 131, and elastically compresses the horizontal elastic member 23. When the adjusting rod 21 is released, the horizontal elastic member 23 is pushed against the adjusting rod 21 to be reset. The end of the top mast 22 is displaced by the groove 211 to the step surface 212, and the tooth groove 223 and the ratchet block 311 are engaged again. Further, when the adjustment lever 21 is not pressed, the adjustment lever 21 is in a state of continuously pushing the top mast 22 by the elastic force of the cross member 23.

3. A set of longitudinal elastic members 5 of the body section 222 of the top mast 22, and the two ends of the longitudinal elastic member 5 respectively respectively abut against the bottom of the slot of the swaying groove 12 and the occlusal section 221 of the top mast 22.

By the spring of the longitudinal elastic member 5, the bite head portion 221 of the top mast 22 is stably fitted to the ratchet block 311.

The above description is only intended to explain the preferred embodiments of the present invention, and is not intended to limit the invention in any way. The changer should still be included in the scope of the intention of the present invention.
