Please refer to Fig. 1 to Fig. 8, a tool handle and a tool connection structure provided by the utility model include: two handles 2, the same number of bolts 3 as the combination holes 211 and more than one tool set 4, the present embodiment Be two bolts 3.

The two handles 2 are generally elongated, and a groove 21 is provided at the top of the two, and a combined hole 211 is formed perpendicular to the grooves 21. The combined hole 211 runs through the front and back of the handle 2 and passes through the groove 21. A concave portion 212 is provided on one side, and the concave portion 212 has a plurality of flanges 213; as shown in Figures 4 and 5, the inside of the flange 213 slightly protrudes out of the combination hole 211, that is, the imaginary circle formed by the inside of the flange 213 and The combination hole 211 is concentric and its diameter is smaller than that of the combination hole 211 . The flange 213 is flexible, and there is a distance 214 between the outer side of the flange 213 and the concave portion 212 .

The latch 3 has a tail section 31 with a slot 32, the side 33 of the slot 32 is inclined to meet the tail section 31, and the tail section 31 is provided with a slope 34, by the inclined side 33 and the slope 34, Eliminate latch 3 to withdraw from or insert handle 2.

Referring to Fig. 4～Fig. 7, this tool group 4, can be the tool of different purposes, as shown in the figure is a pair of scissors, is made up of two blades 41, and the hole 42 of the same number as combined hole 211 is arranged below it, in the middle of these two blades 41 pivotally connected with a shaft 43 .

Insert the lower end of the tool set 4 into the groove 21 of the above-mentioned handle 2, and align the combination hole 211 of the handle 2 with the hole 42 of the tool set 4, and then insert the above-mentioned pins 3 respectively. The inclined surface 34 of the tail section 31 of the bolt 3 causes the flange 213 of the handle 2 to flex outwardly, and the groove 32 is used for the flange 213 to recover its free state, so that the groove 32 of the bolt 3 and the flange 213 of the handle 2 Fitting, the restraining force generated therebetween makes the handle 2, the bolt 3 and the tool set 4 firmly combined. Since the tail section 31 of the latch 3 protrudes from the handle 2, when changing the tool set 4 for different purposes, the latch 3 can be easily pushed back by the inclined surface 34 by hand, and the latch 3 can be taken out smoothly.

The two handles 2 are pivotally connected to each other by the pivot joints 22 inside the middle section; a chute 23 is provided under the pivot joint 22 of one of the handles 2, and a column 231 is passed through the chute 23, and its two ends are respectively A button 232 is fixed, and the cylinder 231 is translated in the slide groove 23 by the button 232 ; and a hook 24 is provided under the pivot joint 22 of the other handle 2 . And the inner side below the pivot joints 22 of the two handles 2 has a circular socket 25 respectively, and a compression spring 26 is arranged between the two sockets 25, which has a pre-compression deformation, so that the spring 26 is fixed on the two sockets. The grooves 25 do not fall off, and the spring 26 keeps the tops of the two handles 2 in a normally closed state; when applying force to the handles 2, the handles 2 form a moment arm with the pivot joint 22 as the fulcrum, and the other side of the fulcrum Then it moves in the opposite direction to the direction of force. When the force is applied to the handle 2 to close the ends of the two handles 2 to the limit, the above-mentioned button 232 can be moved up, so that the cylinder 231 can catch the hook 24, so that the ends of the handle 2 can be kept closed for easy storage, such as Figure 8 shows.

For example, a hollow portion 27 is provided on the outside of the handle 2 of the present invention to prevent the material from shrinking after injection molding, and a plurality of vertically and horizontally distributed reinforcing ribs 271 are provided on the hollow portion 27 to increase the strength of the handle 2 . The outer side of the handle 2 is combined with an elastic member 5, and one side of the elastic member 5 has a plurality of raised protrusions 51, and the protrusions 51 are embedded between the reinforcing ribs 271 adjacent to the handle 2; The contact between the rib 271 and the plurality of protrusions 51 increases the contact area between the elastic member 5 and the handle 2 , and the combination of the two is more stable through the friction force between the two. In addition, when using the tool, the contact between the hand and the elastic member 5 will increase the comfort of use, and the shape and color of the elastic member 5 can be changed to make the appearance more rich and beautiful.

To sum up, the utility model has few components and is not easy to lose, low manufacturing cost, elegant appearance, integrity and variability, simple assembly without special tools, and saves carrying and storage space, which brings convenience to users and improves use efficiency.
