[0043] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0044] The present invention first provides a manual tool in which a tool member can be stored and deployed. Figure 1 , 2 Shows a telescopic pliers according to the present invention, including a telescopic pliers head 5, and a handle and a linkage. The handle includes a handle portion 1 and a handle portion 2. The handle portion 1 has a proximal end 11 and a distal end 12, and the handle portion 2 has a proximal end 21 and a distal end 22. The handle portion 1 can rotate around a pivot 111 located at the proximal end 11, and the handle portion 2 can rotate around a pivot 211 located at the proximal end 21. The pivots 111 and 211 are connected by a connecting member 6. The linkage includes 3 and 4. The linkage 3 has a tool end 31 and a handle end 32, and the linkage 4 has a tool end 41 and a handle end 42. The pliers head 5 is formed by staggered hinging of pliers bodies 51 and 52. The tool end 31 of the linkage 3 is rotatably connected to the tail of the pliers body 52 through a pivot 311, and the handle end 21 of the linkage 3 is rotatably connected to the handle portion 1 through a pivot 321. The tool end 41 of the linkage 4 is rotatably connected to the tail of the pliers body 51 through a pivot 411, and the handle end 41 of the linkage 4 is rotatably connected to the handle portion 2 through a pivot 421.

[0045] When the handle parts 1 and 2 are opened or closed, the clamping head 5 is driven by the linkage parts 3 and 4 to move telescopically relative to the handle, so that it can be set in the working state and the storage state. When in the working state, the clamping head 5 extends outside the proximal ends 11 and 21 of the handle; when in the storage state, the clamping head 5 retracts into the handle and is located between the proximal ends 11 and 12 and the distal ends 21 and 22 of the handle.

[0046] The telescopic pliers are also provided with a linkage mechanism at the proximal ends 11 and 21 of the handle. In this embodiment, the linkage mechanism is the mutually cooperating tooth grooves 112 and 212 as shown in Figure 2 such that when the handle part 1 or 2 moves, the other handle part 2 or 1 moves accordingly. In other embodiments, the linkage mechanism can also be mutually cooperating concave and convex grooves. And in another embodiment, as shown in Figure 3 and 4 and 5, the handle part 1 includes components 101 and 102, the handle 2 includes components 201 and 202. The component 101 has an extension part 1011 that cooperates with the component 201, and the component 202 has an extension part 2021 that cooperates with the component 102. The component 101 and the component 201 are pivotally connected to the shaft 111 at the extension part 1011, and the component 102 and the component 202 are pivotally connected to the pivot shaft 211 at the extension part 2021, thereby forming a linkage mechanism and a connecting part.

[0047] As shown in Figure 6 the linkage parts 3 and 4 are provided with abutting parts 312 and 412 at the tool ends 31 and 41, and grooves 511 and 521 are provided at the tails of the pliers bodies 51 and 52. When the clamping head 5 of the telescopic pliers is in the working state, the abutting parts 312 and 412 respectively abut against the grooves 511 and 521 to control the opening and closing of the clamping head 5.

[0048] The handle parts 1 and 2, the linkage parts 3 and 4, and the clamping head 5 substantially constitute a planar linkage system, such that the clamping head 5 can telescopically move through the linkage parts 3 and 4 along with the opening and closing movement of the handle parts 1 and 2. This linkage system has a critical point as shown in Figure 1 At this time, the pivot shafts 311, 411, 321, and 421 are horizontally on the same straight line. The handle parts 1 and 2 can be opened from the closed state to the critical point. When the clamping head 5 moves towards the proximal ends 11 and 21 of the handle and crosses the critical point, then closing the handle 1 and 2 at this time will cause the clamping head 5 to continue to extend and finally reach the working state. When the clamping head 5 moves towards the proximal ends 11 and 21 of the handle and crosses the critical point, then closing the handle parts 1 and 2 at this time will cause the clamping head 5 to continue to extend and finally reach the working state. On the contrary, when the clamping head 5 moves towards the proximal ends 12 and 22 of the handle and crosses the critical point, then closing the handle 1 and 2 at this time will cause the clamping head 5 to retract and finally return to the storage state.

[0049] In this embodiment, the linkage members 3 and 4 are located on one side of the jaw 5. In another embodiment, the linkage members 3 and 4 are respectively located on both sides of the jaw 5. In another embodiment, the linkage members 3A and 4A are located on one side of the jaw 5, and on the other side, there are provided linkage members 3B and 4B which are equivalent to the linkage members 3A and 4A respectively, as Figure 8 shown. Further, the linkage members 3A and 3B are integrally formed by, for example, sheet metal bending, and the linkage members 4A and 4B are also integrally formed by, for example, sheet metal bending, as Figure 19 , 20 shown.

[0050] In addition, in this embodiment, the pivot shafts 311 and 411 can also coincide, that is, they are actually the same pivot shaft.

[0051] The present invention further provides such a manual tool including more than one tool part. Refer to the embodiments shown in Figure 7 , 8 . In this embodiment, the tool member 5 includes a jaw 5A and a jaw 5B opposite thereto. In this embodiment, the pivot shaft 311 and the pivot shaft 411 coincide, that is, they are actually one pivot shaft. The jaws 5A and 5B are cross-hinged by a jaw body 51 and a jaw body 52 at the pivot shaft 311 (411). In this embodiment, driven by the handle and the linkage members, the tool member 5 has four states relative to the handle: a first working state in which the jaw 5A is deployed outside the proximal ends 11 and 21, as Figure 12 shown; a second working state in which the jaw 5B is deployed outside the proximal ends 11 and 21, as Figure 13 shown; a first storage state in which the jaws 5A and 5B are retracted between the proximal ends 11 and 21 and the distal ends 12 and 22 of the handle, and the jaw 5A faces the proximal ends 11 and 21, as Figure 10 shown; a second storage state in which the jaws 5A and 5B are retracted between the proximal ends 11 and 21 and the distal ends 12 and 22 of the handle, and the jaw 5B faces the proximal ends 11 and 21, as Figure 14 shown.

[0052] In this embodiment, in order to enable the tool member 5 to move between these four states relative to the handle, the handle parts 1 and 2, the linkage members 3 and 4, and the jaw 5 substantially form a planar linkage system, and this system has a critical point as Figure 11 shown. At this time, the pivot shafts 311 (411), 111, 211, 321, and 421 are substantially on the same straight line in the horizontal direction. The handle parts 1 and 2 can be opened from the first or second storage state as shown in Figure 10 or 14 to the critical point as shown in Figure 11 . At this time, (1) if the tool member 5 moves in the direction of the jaw 5A across the critical point, and the handle parts 1 and 2 are closed in the direction of the jaw 5B, then the tool member 5 will be placed as Figure 12The first working state shown; (2) If the tool member 5 moves towards the jaw 5A beyond the critical point and the handle portions 1 and 2 converge towards the jaw 5A, the tool member 5 will be placed as shown in Figure 14 The second storage state shown; (3) If the tool member 5 moves towards the jaw 5B beyond the critical point and the handle portions 1 and 2 converge towards the jaw 5A, the tool member 5 will be placed as shown in Figure 13 The second working state shown; (4) If the tool member 5 moves towards the jaw 5B beyond the critical point and the handle portions 1 and 2 converge towards the jaw 5B, the tool member 5 will be placed as shown in Figure 12 The first storage state shown.

[0053] As Figure 8 shown, torsion springs 501 and receiving grooves 502 are provided at the mating surfaces of the pliers bodies 51 and 52 at the pivot 311 (411), so that the jaws of the jaws 5A and 5B are subjected to an opening biasing force. In this embodiment, the pivots 111 and 211 are respectively pin posts. As Figure 16 shown, when the jaw 5A or 5B is in the working state, the pin posts 111 and 211 respectively abut on both sides of 5B or 5A, so that the jaws can be opened and closed under the action of the torsion spring 501. In a further embodiment, grooves 511, 512, 521 and 522 are provided at the abutting positions of the jaws 5A and 5B with the pin posts 111 and 211, so that when using the jaw function, the opening angle of the handle is smaller, which is convenient for holding and applying force, and the storage area inside the handle is larger. In another further embodiment, instead of providing the grooves 511 and 512, arc-shaped grooves 1110 and 2110 are provided at the mating positions of the handle with the pin posts 111 and 211, and the pin posts 111 and 211 can move in the arc-shaped grooves 1110 and 2110. As Figure 17 、 18 shown, the same effect can be achieved that when using the jaw function, the opening angle of the handle is reduced, which is convenient for holding and applying force, and the storage area inside the handle is larger. In addition, when the widths of the functional components at both ends are inconsistent, by setting grooves or arc-shaped grooves, it can basically meet the requirement that when using different functional components, the opening angle of the handle changes little, achieving a comfortable feeling for the user and convenient force application.

[0054] As Figure 21 shown, the tool member 5 can also be other types of double-headed pliers.

[0055] As Figure 22 shown, the tool member 5 can also be a double-headed tool.

[0056] As Figure 23 、 24 and 25 shown, the tool member 5 can also be a double-headed screwdriver, and the bit can also be various sockets.

[0057] The handle part can also be configured with other functional components, just like a conventional multi-functional pliers. And the functional components can be used when the head is stored in the handle, with simple, fast, convenient and safe operation.

[0058] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
