Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used to illustrate the present invention.

As shown in fig. 1 to 2, a clamp convenient to adjust for mechanical assembly comprises a clamp frame 12 and a base plate 1 arranged below the clamp frame 12, wherein an upright post 2 is vertically fixed at the middle position of the upper part of the base plate 1, a support arm 6 horizontally arranged is fixed at the middle part of the outer wall of the clamp frame 12, and the end part of the support arm 6 far away from the clamp frame 12 is fixed at the upper end part of the upright post 2; the middle part of the inner cavity of the clamp frame 12 is movably hinged with a widening clamping arm 10 through a hinge 11, and the middle position on the upper surface of the widening clamping arm 10 is provided with a sliding groove 13; the vertical downward screw thread of the outer edge of the upper part of the clamp frame 12 is screwed and penetrated with a long screw rod 8, the vertical downward screw thread of the middle part of the clamp frame 12 is screwed and penetrated with a short screw rod 7, and the short screw rod 7 is inserted in the sliding groove 13.
