Description

Fixture adjustment structure improvement

This creation department is concerned with a "improvement of the adjustment structure of the jig", especially one that is time-saving and labor-saving.

According to the traditional clamping work, in the case of two workpieces of different thicknesses, it is necessary to use a plurality of different clip size spring clips. The creator developed a spring clip improved structure, the structure The type is as disclosed in the National Patent Publication No. M390847 (as shown in the attached file), which is mainly composed of two handles combined with two clamping arms and one hand positioning mechanism, wherein the handle positioning mechanism is The shaft body, the seat body, the handlebar, the compression spring and the like are combined, the upper end of the shaft body is locked on the surface of the handle, and the lower end of the shaft body is embedded in the inner diameter of the seat body, and the bottom end of the seat body is Locked on the surface of the handle, the front end of the handle abuts against the groove above the seat body, the compression spring is disposed between the handle and the neck of the seat body, and an aperture is formed on the face of the handle, and the aperture is utilized The setting can be resisted to the surface of the shaft body to control the fixing of the two handles, and the present invention is characterized in that the ends of the two clip arms of the spring clip are each formed to have a disc body in the disc body. The central part has a through Aperture, for a screw is inserted through the knob, while the bottom peripheral edge of the disk bodies produced becomes ratchet (or convex teeth) are arranged, additionally, The upper end of the arm of the neck of the two handles of the spring clip is also formed to have a disc body each having a size, a shape and a thickness similar to the disc body on the end of the clip arm of the spring clip, and in the circle The central portion of the disk body is formed with a screw hole seat, and a screw hole is formed in a central portion of the screw hole seat. In addition, a peripheral surface of the top surface of the disk body is formed as a ratchet (or concave tooth) arrangement, and a compression spring ring set can be utilized. Outside the screw hole seat, and with the screwing of the knob screw, the two disc bodies can be combined up and down to form a rotatable joint mechanism.

However, after the developer created the creation case, he was not complacent, and continued to think about R&D in the spirit of excellence, striving to make this structural feature more practical and useful; the creator developed in the follow-up During the process, it was found that in the above-mentioned structure, when the knob screw is locked or loosened, it needs to be slowly rotated. In addition to delaying the work, it is also easy to cause hand fatigue, so it is necessary to improve the breakthrough.

Therefore, the person who wants to reveal this creation is a new type of structural designer who has made improvements and breakthroughs in the shortcomings of the creator's related previous case structure.

It is mainly aimed at improving the problem of the problem that the knob screw of the conventional spring clip structure previously developed by the creator is too slow to rotate.

The present invention provides an improved adjustment structure of a jig, comprising: a jig body, two clamping jaws, two pressing components and a handle positioning device, wherein the clamping body has two clamping arms, and the two clamping arms are mutually interlocked and pivoted. There is a handle at the end, a torsion spring is arranged on the second-hand interposer, and an accommodating space is arranged on each inner recess, and the two clamp arms and the two clamps are combined by the latching lugs at one end, and the latches are engaged in the latches. The surface has a ratchet or convex toothed engaging tooth, and a through hole is arranged in the center. The pressing component has a shaft bolt, a spring, a washer and a control handle, and the shaft bolt is placed on the clip. In the through hole of the arm and the clamp, the protrusion is formed by the enlarged portion of one end and the clamp arm or the clamp, and the other end is passed out through the through hole to directly or indirectly pivot with the control handle, through the pivot group The relationship will allow the control handle to be swung on the shaft bolt. The spring is clamped between the clamp arm and the clamp of the clamp, and is placed by the bolt. The spring elastic support can be used. Actively push the clamp arm and the clamp of the clamp under the normal state of controlling the handle release The block is remote from each other, and a joint portion is formed on each side of the control handle, and the joint portion is provided with a pressing block which is perpendicular to the axial direction and protrudes in an eccentric manner, and the control handle is formed by the joint portion and the shaft bolt to make the control handle When the device is pulled, the pin can be pulled by the pressing block of the pressing block, and a gasket is arranged on the shaft bolt between the control handle and the latching protrusion, and the handle positioning device is obliquely installed in the second-hand pad. The handle positioning device is composed of a shaft body, a body, a pressing handle and a compression spring, thereby improving the adjustment structure of the clamp.

The creation provides an improved adjustment structure of the jig, which uses the control handle to provide the pulling and the abutting by the pressing block, and the locking or unscrewing of the clicking block can be easily achieved without slow rotation. In addition to avoiding delays in working hours, it is also more time-saving and labor-saving.
