Problems solved by technology
On the one hand, it cannot be used for the coil operation with a smaller diameter; on the other hand, because the chain link is a metal material, it will form strangulation marks on the pipe wall during operation, resulting in surface damage; it is used for hard and smooth pipe walls Slip phenomenon is also prone to occur when the pipe coiler is used; moreover, the cost of the existing pipe coiler is relatively high

The invention provides a pipe spinner adopting ratchet locking, and relates to hardware tools. A pipe fastening component is a toothed belt (2), and the right and left sides of a handle (1) are provided with longitudinal grooves; the right and left sides of the front end of the handle (1) are provided with sliding clamps (3) and a ratchet locking device separately, and the front and rear sides ofthe handle (1) are each provided with a longitudinal sliding chute (6); the sliding clamps (3) are embedded into the sliding chutes (6), and the ratchet locking device comprises a gear (7) and a ratchet (8) which are fixed coaxially; the gear (7) is arranged in the groove in the front end side of the handle (1), and one end of the toothed belt (2) is matched with and fixed to teeth of the toothedbelt (2) through latches (4) of the sliding clamps (3); and the other end of the toothed belt (2) is arranged in the groove in the other side of the handle (1) through the inner side of the gear (7),and matched with the teeth of the toothed belt (2) through the gear (7). The pipe spinner has the advantages of the simple structure, low manufacturing cost, convenient use and good using effect.
Description
technical field [0001] The invention relates to a hardware tool, in particular to a pipe spinner which is locked by a ratchet. Background technique [0002] The commercially available pipe coiler is a kind of hardware hand tool that is used to twist the pipe body when the pipe is connected by combining a chain and a handle. Since the chain is connected by multiple fixed-length metal links, there are certain limitations in use. On the one hand, it cannot be used for the coil operation with a smaller diameter; on the other hand, because the chain link is a metal material, it will form strangulation marks on the pipe wall during operation, resulting in surface damage; it is used for hard and smooth pipe walls When, slip phenomenon also easily occurs; And, the cost of existing pipe coiler is also relatively high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pipe coiler with simple structure, low cost, convenie...
