Connecting portion 104 is equipped with the first through-hole 105 unanimous with lead screw 200 axis direction and transversely sets up the holding hole 106 that link up with first through-hole, holding hole 106 embeds there is locking block 300, be equipped with the second through-hole 301 that corresponds with first through-hole axial on the locking block 300, the diameter of second through-hole 301 is greater than the diameter of lead screw 200, make the lead screw can be in the axial displacement of unrestraint ground in the second through-hole, set up screw thread 302 on one side inner wall of second through-hole 301, the central angle that screw thread 302 corresponds is not more than 180, screw thread 302 moves along with locking block 300.
The locking block 300 acts on an elastic element 400, the locking block 300 enables the thread 302 to be matched with the screw rod 200 by means of the elastic force of the elastic element 400 for converting the rotation of the screw rod around the axis of the screw rod into the movement of the screw rod along the axis of the screw rod, and the locking block enables the locking block to be disengaged from the screw rod with the thread movement by overcoming the elastic force of the elastic element so as to rapidly and axially move the screw rod. In particular, the locking block 300 is exposed at the connecting portion 104, and the screw thread is disengaged from the screw rod against the elastic force by pressing the locking block. The illustrated elastic element is a helical compression spring, both ends of which are supported on the locking block and the connecting portion, respectively.
The edges of two sides of the clamp body 100, the first clamping arm 101 and the second clamping arm 102 are provided with reinforcing ribs 107, and weight-reducing grooves 108 are arranged among the reinforcing ribs.
The length H3 of the connection portion 104 in the direction of the screw axis is 39 to 45 mm. The length of the connecting part can ensure that the screw rod is coaxial with the first through hole, and the clamping force is maximum.
The joints of the first clamping arm 101, the second clamping arm 102 and the clamp body 100 are all arc-shaped, and the ratio of the maximum clamping distance H4 (namely the maximum clamping distance of the clamp body) defined by the first clamping part 103 and the second clamping part 201 to the arc-shaped radius R at the joint of the first clamping arm and the clamp body is 3: 1-5: 1. The arc radiuses of the G-shaped clamps of four inches, six inches and eight inches (namely the size of the maximum clamping distance of the clamp body) are respectively 30mm, 35mm and 40mm according to different models of products. The arc radius is a point with larger stress, and the larger radian radius can ensure that the deformation of the clamping arm is smaller.
The ratio of the maximum clamping distance H4 defined by the first clamping part and the second clamping part to the maximum width H1 of the inner surface of the clamp body is 6: 1-10: 1, and the maximum widths of the inner surface of the clamp body of the G-shaped clamp with four inches, six inches and eight inches are respectively 16mm, 18mm and 20mm according to different models of products.

According to the quick G-shaped clamp, the locking block enables the threads to be matched with the screw rod under the normal state by means of the elasticity of the elastic element so as to convert the rotation of the screw rod around the axis of the screw rod into the movement of the screw rod along the axis of the screw rod, and therefore an object is clamped or loosened by rotating the screw rod. When the screw rod needs to be moved quickly, the locking block is pressed to overcome the elastic force to enable the threads to be disengaged from the screw rod, and then the screw rod can be moved axially quickly. After the screw rod is moved in place, the locking block is released, and the locking block can restore the matching of the screw thread and the screw rod under the action of elasticity.
Example 2
As shown in fig. 6-7, the receiving hole of the quick G-clamp is vertically disposed on the connecting portion, so that the locking block moves vertically. The rest of the structure is the same as that of embodiment 1, and is not described again.
