[0002] In the rotation process of the existing wrench with limited operating space, it is generally necessary to pull out the wrench after turning a certain angle, and change the position of the wrench before re-aligning for the next rotation within the angle range. Handling the wrench in tight spaces is particularly inconvenient and time consuming
Therefore, there is a wrench with a ratchet in the prior art, which can cover the nut, and can repeatedly unscrew the nut with a wrench within a certain angle range without pulling out and re-aligning the wrench, but this wrench is a closed-loop Yes, the prerequisite for its use is that the nut must be able to be completely inserted into the wrench, and the nut that cannot be fully inserted cannot be used, and the application occasions are limited.

Embodiment Construction
[0009] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.
[0010] Such as figure 1 As shown, a wrench capable of continuous rotation includes a handle 1, the right end of the handle 1 is provided with a sleeve 2, the left end of the handle 1 is provided with a jacket 8, and the jacket 8 is provided with 4 pawls 3 and 4 telescopic rods 6 , there is a wrench set 5 in the middle of the jacket 8, the wrench set 5 is connected by a screw 9, the edge of the wrench set 5 is provided with a gear 4 and a groove 7, it should be noted that the pawl 3 and the gear 4 are meshed, and the telescopic rod 6 The roller at the bottom is in the groove 7. Groove 7 and screw rod 9 are on both sides of gear 4 respectively.
[0011] The working principle of the present invention is: when in use, turn the screw rod 9 to select a suitable size and use the wrench set 5 to cover the nut to be twisted, and then turn the handle 1 countercl...

The invention relates to a wrench capable of continuously rotating. The wrench comprises a handle, wherein a sleeve is arranged at the right end of the handle, an outer sleeve is arranged at the leftend of the handle, four pawls and four telescopic rods are arranged on the outer sleeve, a wrench sleeve is arranged in the middle of the outer sleeve, the wrench sleeve is connected by a screw rod, agear and a groove are arranged at the edge of the wrench sleeve; the pawls are engaged with the gear; and rollers at the bottoms of the telescopic rods are arranged in the grooves. The grooves and screws are separately arranged at the two sides of the gear. By arranging the gear structure, during use, the nut is sleeved with the wrench sleeve, and then the wrench is rotated up and down within a certain angle, so that the nut can be unscrewed.
Description
technical field [0001] The invention relates to the field of hand tools, in particular to a continuously rotating wrench. Background technique [0002] In the rotation process of the existing wrench with limited operating space, it is generally necessary to pull out the wrench after turning a certain angle, and change the position of the wrench before re-aligning for the next rotation within the angle range. It is particularly inconvenient and time-consuming to operate the wrench in a narrow space by means of the wrench. Therefore, there is a wrench with a ratchet in the prior art, which can cover the nut, and can repeatedly unscrew the nut with a wrench within a certain angle range without pulling out and re-aligning the wrench, but this wrench is a closed-loop Yes, the prerequisite for its use is that the nut must be able to be fully inserted into the wrench, and the nut that cannot be fully inserted cannot be used, and the application occasions are limited.
