Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
In the description of the present application, it is to be noted that the terms "middle", "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present application and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.
Examples
As shown in fig. 1 to 8, the utility model provides a laborsaving spanner of little space tapping, including bolt 1 and cylinder 2, bolt 1 is equipped with two, all includes bolt head 3 and screw rod 4 to 2 both ends of cylinder are located to the symmetry respectively, 2 axial direction of cylinder go up the middle part and are equipped with circular through-hole 5, radial direction upward middle part is equipped with square through-hole 6, two bolts 1 install respectively in circular through-hole 5 at both ends about cylinder 2 through screw rod 4, and screw thread opposite direction when these two bolts 1 install, square through-hole 6 is used for the installation to attack the lead screw, 4 tip of screw rod of two bolts 1 all with tapping rod surface contact to in being fixed in the square through-hole 6 of cylinder 2 with the tapping rod, through the screw in length of adjusting two bolts 1, the packing force of two adjustable bolts 1 to attacking the lead screw.
Preferably, the diameter of the circular through hole 5 is matched with the outer diameter D1 of the screw rod 4 of the two bolts 1.
Preferably, the aperture S of the square through hole 6 is larger than the outer diameter of the tapping rod.
