Detailed ways

In order to understand the technical features and practical effects of the present utility model in detail, and to implement it according to the contents of the specification, the detailed description of the preferred embodiment as shown in the figure is as follows:

As shown in Figures 1 to 3, the utility model provides a compound wrench, which is composed of a handle 10, a central rod 20, a holding part 30 and a tool part 40, wherein:

The handle 10 is made of plastic and has two opposite ends. The central rod 20 is made of solid metal and includes a first end 21 and a second end 22. The central rod 20 is embedded in the In the handle 10 and the two ends 21, 22 protrude from both ends of the handle 10, the first end 21 is recessed with a groove 212 and the groove 212 is non-circular, preferably, The groove 212 is hexagonal; preferably, the second end portion 22 is a hexagonal through portion penetrating through the end portion of the handle 10 .

The holding part 30 includes a sleeve 36 disposed outside the first end 21 of the center rod 20, a ball 34 and a spring 38; On the wall of the groove 212 in the end 21 and the ball 34 can protrude into the non-circular groove 212;

The sleeve 36 is sliding and is disposed around the first end 21 of the central rod 20. The sleeve 36 pushes the ball 34 so that the ball 34 partially protrudes into and touches the non-circular groove 212 and Allowing the ball 34 to retract from the non-circular groove 212 into the sleeve 36, the sleeve 36 has an inner surface and the inner surface has a flange 362 surrounding the inner surface, the inner surface is provided with a The surrounding groove 364 located under the flange, when the sleeve 36 is slid so that the surrounding groove 364 is aligned with the ball 34, the sleeve 36 provides an accommodating space for the ball 34 to pass through the groove 212 retracted into the containing space;

The spring 38 is arranged on the periphery of the first end 21 of the central rod 20 and provides an active force to support the sleeve 36 so that the flange 362 adjacent to the spring is against the ball 34, and pushes the sleeve 36 against the ball 34. The outside of the grip sleeve 36 can press the ball 34 to push it into the groove 212;

The tool piece 40 is detachably embedded in the first end portion 21 of the central rod 20 by utilizing the holding portion 30, and the tool piece 40 can be a wrench head, for example: as shown in FIG. 1 , the tool piece is A sleeve type wrench head 40, as shown in Figure 4, the tool part is an open type wrench head 40A, as shown in Figures 5 to 7, the tool part is an adjustable wrench head 40B, as shown in Figures 8 to 10 As shown, the tool part is a ratchet wrench head 40C; therefore, the compound wrench can replace the tool part according to the use requirements, and can be adjusted according to various fixing parts, such as screws, bolts or nuts, using the sleeve 36 can replace different types of tool pieces in use; the tool piece 40 includes a connecting column 42 and the outer edge of the connecting column 42 has a non-circular through part that matches the non-circular groove and a The engaging groove 422 provided on the connecting column 42 is detachably engaged with the ball 34, and the engaging surface between the engaging groove 422 and the ball 34 allows the wrench head 40, 40A, 40B, 40C are more firmly connected to the first end 21 of the central pole 20; preferably, the penetrating portion of the outer edge of the connecting column 42 is a hexagonal penetrating portion.

Based on such an arrangement, the wrench head 40, 40A, 40B, 40C can be replaced according to the needs of different uses. The compound wrench can be widely used in fixing and loosening various kinds of fixing parts, and the solid central rod 20 makes the composite wrench have sufficient structural strength to withstand the torque generated by the fixing part, showing better durability.

The sleeve 36 is slidable. When the surrounding groove 364 inside the sleeve 36 and the ball 34 are aligned, the ball 34 is retracted from the groove 212 into the sleeve 36 and disengaged. With the engaging groove 422 on the connecting post 42 , the tool piece 40 can be disassembled from the first end 21 of the central rod 20 .

The tool part can be disassembled from the groove 212, and tool parts of different types and sizes can be replaced and inserted in the groove 212 according to the use requirements. Therefore, the composite wrench requires different replacements according to different working conditions. There are various types or sizes of tool parts, which have high convenience and diverse applications in use.

As shown in Figure 11, multiple wrench heads 40, 40A and a handle 10 are placed in the same tool box, so that the user can easily carry the composite wrench, and the wrench head 40 can be replaced under different working conditions. , 40A, according to the advantages of the composite wrench of the utility model, the user is more convenient and labor-saving in use and carrying.

But above-mentioned person, only preferred embodiment of the present utility model, should not limit the scope of the present utility model implementation with this, and generally according to the utility model patent application scope and the simple equivalent change that content of specification is made and Modifications should still fall within the scope covered by the utility model patent.
