Embodiment Construction

[0018] Such as figure 2 with image 3 As shown, the fast loosening and tightening threadless clamp of the present invention includes: left chuck 4, right chuck 6, square knurled sliding rod 14, clamping mechanism and clamping handle 7, in the left chuck 4 and right chuck There are square holes 13 in the corresponding positions. The square knurled sliding rod 14 passes through the square hole 13 of the left chuck 4 and the square hole 13 of the right chuck 6, and passes through the square knurled sliding rod 14 of the right chuck 6. The end of the chuck is hinged with the clamping handle 7, and the clamping mechanism is installed in the left chuck 4, which supports or loosens the square knurled sliding rod 14 passing through the square hole 13 of the left chuck 4.

[0019] Such as Figure 1 to 4 As shown, the front end of the left chuck 4 is opened with a front connecting rod cavity 17, and the rear end of the left chuck 4 is opened with a rear connecting rod cavity 18, between t...

Abstract

The invention relates to a quick loosening and fastening thread-free clamp, which comprises a left clamping head (4), a right clamping head (6), a square knurl sliding rod (14), a clamping mechanism and a clamping handle (7). A square hole (13) is respectively arranged at the corresponding position of the left clamping head (4) and the right clamping head (6), the square knurl sliding rod (14) penetrates through the squares (13) of the left clamping head (4) and the right clamping head (6), the end of the square knurl sliding rod (14) penetrating through the right clamping head (6) is hinged with the clamping handle (7), and the clamping mechanism is installed in the left clamping head (4) and abuts against or loosens the square knurl sliding rod (14) penetrating through the square hole (13) of the left clamping head (4). The quick loosening and fastening thread-free clamp adopts the rotating mode of a loosening handle and the clamping handle to fix the square knurl sliding rod, thereby being capable of quickly clamping and loosening work pieces, short in time cost by clamping and loosening of the work pieces and high in labor efficiency.

Description

Technical field [0001] The invention relates to a clamp, in particular to a fast loosening and tightening threadless clamp. Background technique [0002] The fixture is a fixture widely used in factories to fix the workpiece for processing. Commonly used clamps include movable jaws and fixed jaws. The movable jaws are driven by a screw rod. Because the screw drive requires several turns to achieve the purpose of fixing and loosening, there are problems in the use of existing clamps that it takes a long time to clamp and loosen the workpiece and the labor efficiency is low. Summary of the invention [0003] The purpose of the present invention is to solve the shortcomings of long time and low labor efficiency for clamping and loosening workpieces in the existing clamps, and to provide a fast loosening and tightening screwless clamp. [0004] In order to accomplish the purpose of the present invention, the present invention adopts the following technical solutions: [0005] The fast ...
