Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improved structure of a clip that is attached to the head of a screw that immovably fixes a vehicle body.

[Prior Art] When repairing a car body that has been deformed due to a collision, the car body is generally fixed immovably on the ground and then restored.In this case, the car body is once lifted using a known jack and then fixed to a fixed support base. This eliminates the complicated work of interposing it under the vehicle body and supporting it on the fixed support by returning the jack.
The applicant has proposed an example of use as shown in FIG. 5 as one embodiment of the invention in Utility Application No. 100794/1983. That is, in the same figure, a cylinder 24 is vertically established on the seat plate 23, and a screw shaft 2 is inserted into the cylinder 24 so as to be able to rise and fall freely.
6 are screwed together, a receiving metal fitting 30 is suspended along one side of the cylinder 24 from the upper protrusion of this screw shaft 26, and an annular receiving piece 32 fixed to the lower end of this receiving metal fitting 30 is attached to the outer periphery of the cylinder 24. The screw jacks 22 are fixedly attached to the sliding ring 33 that is loosely fitted to the slide ring 33, and two screw jacks 22 are arranged along both side edges of the vehicle body, and both ends of a pipe 38 provided in the vehicle width direction are connected to each other. The vertical plate 2a is fixed to the annular body 39 which is inserted into the annular receiving piece 32 and fixed to the pipe 38.
A pair of clamping pieces 3, 3 provided at both ends of the frame clamp and fix a part of the lower surface of both side edges of the vehicle body, and through holes 7, 8 provided in a bracket 5 fixed to the vertical plate 2a.
Both ends of the pipes 34 arranged along both side edges of the vehicle body are fitted into one of the through-holes 8, and a planar rectangular frame is assembled with the two pipes 34 and 38, respectively. A chain 35 is inserted through the chain 35, and both ends of the chain 35 are hooked and tensioned to a catch 37 fixed to the ground using an anchor bolt 36 to prevent each jack 22 from sliding sideways, support the vehicle body, and apply external force during repairs. Even if it was added, it was fixed so that it could not be moved.

On the other hand, when repairing a car body that has been deformed due to a collision, etc., it may be necessary to measure whether the car body has been restored to its original dimensions. , the dimension between each reference point is measured using a length measuring machine.

[Problems to be solved by the invention] When setting such a length measuring device on the underside of a vehicle body, the clamping tool 1a for clamping the vehicle body is attached to a pipe 3 stretched between screw jacks 22 in the vehicle width direction.
8, and these pipes 38 are arranged in a transverse manner at the front and rear of the underside of the car body, which obstructs the loading and setting of the length measuring machine, making measurement extremely difficult, and in effect preventing length measurement. This makes it impossible to measure dimensions between reference points using a machine.

Therefore, an object of the present invention is to provide a clamping tool that can be directly attached to the upper part of a jack without using the pipe 38 provided transversely on the underside of the vehicle body as described above.
