Embodiment 1

[0018] Embodiment 1: as Figure 1-6 As shown, a fast-clamping adjustable wrench includes a movable clamp block 1, a fixed clamp block 2, a screw rod 3, a roller 4, a spring 5, a support rod 6 and a push rod 7, and the roller 4 is installed on the fixed clamp block 2 In the roller groove 21 on the top, one end of the screw rod 3 is movably connected with the movable clamp block 1, and the other end is matched with the roller 4. Turning the roller can drive the screw rod to move up and down, and then drive the movable clamp block to move up and down to adjust the movable clamp block The distance between the clamp and the fixed clamp is suitable for parts such as screws of different sizes. One end of the spring 5 is connected with the movable clamp block 1, and the other end is connected with the fixed clamp block 2. Using the principle of leverage, pressing one end of the movable clamp block can quickly clamp the screw, and at this time the spring is in a compressed state. One ...

Abstract

The invention discloses a shifting wrench capable of conducting quick clamping. The shifting wrench capable of conducting quick clamping comprises a movable clamping block, a fixed clamping block, a screw rod, a rolling wheel, a spring, a supporting rod and a push rod; the fixed clamping block is provided with a rolling wheel groove, and the rolling wheel is installed in the rolling wheel groove; one end of the screw rod is connected with the movable clamping block, and the other end of the screw rod is matched with the rolling wheel; one end of the spring is connected with the movable clamping block, and the other end of the spring is connected with the fixed clamping block; one end of the supporting rod is fixedly installed at one end of the movable clamping block, and the other end of the supporting rod is matched with a through hole in the fixed clamping block; and the push rod is movable installed on the fixed clamping block and is matched with the supporting rod. The shifting wrench capable of conducting quick clamping is simple in structure, convenient to operate and good in practicality.

Description

technical field [0001] The invention relates to the field of hardware tools, in particular to a fast-clamping adjustable wrench. Background technique [0002] A monkey wrench is a tool for tightening or loosening angled screws or nuts. When the existing adjustable wrench is turning the nut, every time the nut is turned at a certain angle, it is necessary to remove the wrench to separate the jaws of the wrench from the nut, and then change the angle to re-align and clamp the nut. In addition, when tightening nuts or bolts, a part needs to be manually tightened, and then a wrench is used, and the wrench cannot flexibly clamp the nuts or bolts. This process is time-consuming and laborious, reducing work efficiency. Contents of the invention [0003] Aiming at the shortcomings in the background technology above, the present invention provides a quick-clamping adjustable wrench, which can quickly and flexibly clamp nuts or bolts, without repeated disassembly and assembly duri...
