The lever-type vehicle actuating clamp comprises a handle cylinder 10 and a lever-type clamp 20 fixedly arranged in the handle cylinder 10. It is contemplated that the lever actuated clamps may also include other functional modules such as wires, assembly modules, electrical connection modules, etc. connected to the lever clamps 20, which are well known in the art and will not be described in detail herein.

The handle tube 10 has a tubular structure, which is not only used for holding a user's hand, but also has an insulating effect and protects the connection between the lever type clamp 20 and a wire. Therefore, the handle tube 10 may be made of a non-metallic material, and further, it may be made of plastic. It is contemplated that, of course, when fitted over the connection of the lever clamp 20 to the wire, the handle barrel 10 will deform and tightly bind the connection of the lever clamp 20 to the wire. In fig. 1, the handle barrel 10 is cylindrical due to drawing limitations. The handle tube 10 also has a receiving groove 11, and the receiving groove 11 is used for receiving a lever 26 of the lever clamp 20, which will be described in detail below.

The lever type clamp 20 comprises an upper clamp 21, a lower clamp 22 pivoted with the upper clamp 21, a pivot 23 pivoted with the upper clamp 21 and the lower clamp 22, a pull rod 24 penetrating between the upper clamp 21 and the lower clamp 22, an elastic member 25 sleeved on the pull rod 24 and clamped between the upper clamp 21 and the lower clamp 22, and a lever 26 movably arranged on the pull rod 24 and abutted against the upper clamp 21. The upper and

lower clamps

21, 22 may have the same structure to improve compatibility and interchangeability, thereby reducing cost. In order to improve the convenience of clamping and the compactness of the whole mechanism, the upper and

lower clamps

21, 22 have an arc structure in the section along the opening and closing direction of the upper and

lower clamps

21, 22, so that the upper clamp 21 comprises an upper arc top 211 and the lower clamp 22 comprises a lower arc top 221. The upper arc top 211 is opposite to the lower arc top 221, so as to form a cavity for accommodating the elastic member 25. The upper and

lower clamps

21, 22 also have a through hole 213, respectively. The location of the through hole 213 will be described in the following structure of the pull rod 24. The lower jaw 22 also includes a wire connecting end 222. The wire connection end 222 is accommodated in the handle tube 11 and is used for external wire connection and fixation. The pivot 23 is provided at one end of the upper and

lower clamps

21, 22, which eliminates the need for a user to hold the handles of the clamps in relation to prior art vehicle actuating clamps. The connection and fixing of the pivot 23 should be prior art and will not be described herein. The pull rod 24 is inserted into the through hole 213 and includes a plurality of reverse buckles 241 arranged along the axial direction thereof. The inverted buckle 241 is V-shaped in a cross section along the axial direction of the pull rod 24, and an included angle between one side of the V-shape facing the lever 26 and the axial direction of the pull rod 24 may be an acute angle or a right angle. In this embodiment, the included angle is a right angle. A plurality of the undercuts 241 are provided for adjusting the size of the opening of the upper and

lower clamps

21, 22, thereby facilitating accommodation of tabs for automotive batteries of different diameters. In this embodiment, the pull rod 24 is disposed at a side away from the upper and

lower arc tops

211, 221, and the pull rod 24 and the handle tube 10 are disposed at two sides of the upper and

lower arc tops

211, 221, so as to provide a higher fulcrum for the lever 26, thereby increasing the stroke of the lever 26. Since the pull rod 24 is disposed at a side away from the upper and lower arc tops 211, 221, the through hole 213 for passing through the pull rod 24 is also disposed at a side away from the upper and lower arc tops 211, 221. In order to enable the pull rod 24 to move smoothly, the axial direction of the pull rod 24 is parallel to the opening and closing direction of the upper and

lower clamps

21, 22. The elastic member 25 may be a spring, which is sleeved on the pull rod 24 and clamped between the upper and

lower clamps

21, 22, and is always in a state of forcing the upper and

lower clamps

21, 22 to be opened, so as to prevent the pull rod 24 from being loosened when not in use. One end of the lever 26 is pivotally connected to the free end of the pull rod 24, and a through hole is formed in the pull rod 24 to pass through the pivot shaft formed on the pull rod 24. In this embodiment, for simplicity and convenience, a chicken head groove is provided on the pull rod 24 to provide an axis on the lever 26. The lever 26 includes a supporting point 261, a connecting section 262 connected to the pulling rod 24, and a pressing section 263 disposed at the other side of the supporting point 261 opposite to the connecting section 262. The support point 261 is supported on the upper jaw 21, in particular on the upper arc top 211 of the upper jaw 21. The length of the connecting section 262 is smaller than that of the pressing section 263, so that the pull rod 24 has a longer stroke. It is contemplated that the support point 261 may be supported on the upper jaw 21 when the lever type vehicle actuating clip is in use. When not in use, the lever 26 can rotate 180 degrees around the pull rod 24, so that the supporting point 261 faces away from the upper arc top 211 of the upper clamp 21, so that the lever 26 can be buckled on the handle barrel 10, and particularly, the pressing section 263 can be received in the receiving groove 11 of the handle barrel 10, as shown in fig. 3. In practical use, when the lever 26 is pressed, the upper and

lower clamps

21 and 22 are closed and the inverted buckle 241 is clamped on the side wall of the upper clamp 21 to maintain the closed state of the upper and

lower clamps

21 and 22, and when the pressing of the lever 21 is released and the inverted buckle 241 is pushed to be out of clamping with the upper clamp 21, the upper and

lower clamps

21 and 22 are opened under the action of the elastic member 25.

Compared with the prior art, the lever type automobile starting clamp provided by the invention has the advantages that the pivot 23 is arranged at the tail parts of the upper clamp 21 and the lower clamp 22, so that the clamp handles are not needed, and the volume can be reduced by about half. And the lever 26 enables the vehicle starting clamp which no longer has a clamp handle to complete the clamping function, specifically, the lever type clamp 20 comprises the pull rod 24, an elastic member 25 sleeved on the pull rod 24, and a lever 26 pivoted at one end of the pull rod 24, a V-shaped reverse buckle 241 is arranged on the pull rod 24, the lever 26 is V-shaped, the supporting point 261 is arranged at the vertex of the V-shape, so that when the lever 26 is pressed, the upper and

lower clamps

21 and 22 are folded, and the reverse buckle 241 is clamped on the side wall of the upper clamp 21 to maintain the folded state of the upper and

lower clamps

21 and 22. When the upper and

lower clamps

21 and 22 are required to be opened, the user lifts the lever 26 and pushes the pull rod 24 to disengage the upper clamp 21, so that the upper and

lower clamps

21 and 22 are opened by the elastic member 25. Therefore, the lever type automobile starting clamp provided by the invention can achieve the purpose of removing the clamp handle in the prior art, so that the whole volume can be reduced by almost half, the occupied space is reduced, and the transportation cost is reduced.
