The technical field to which the invention belongs] V. Description of the invention (1)-4 N, Yang ",# 7 Wengen, especially a kind of simple and low cost plum wrench structure with reverse reset. [Previous technology] One-click, the currently known general plum wrench structure is mainly using the sleeve mouth set by the wrench to set on the hexagonal screw joint, and then apply ~ plate power channel to make the screw The combined parts achieve the effect of locking and unloading, as shown in the first and second figures of the attachment (attached to US Patent No. 6 6 5 5 2 3 9) ^ But 'Generally known wrenches want to achieve the locking and unloading effect of the screwed parts It is often possible to use a Torx wrench for multiple reciprocating movements. Generally, when the lock is unloaded = $ pieces, the periphery of the screwed part often has obstacles. Therefore, when the Torx wrench moves the screwed part to After the angle at which the obstructions come into contact, you need to remove the Torx wrench from the screw, and then align the socket part of the Torx wrench with the hexagonal socket of the screw, before you can move the screw again. After repeated pulling, removing, and aligning the sleeve card, the screwman's locking and unloading effect can be achieved after the complicated procedures of multiple pulling. Therefore, this conventional general plum wrench structure requires a large number of plum wrenches. The design of taking out and aligning the hexagonal socket will actually cause the user to reverse the reset and generate time-consuming shortcomings. 'This design needs to align the socket part of the Torx wrench with the hexagonal socket of the screw. Therefore, if it is used in a narrow space, it is easy to lack the space due to the lack of space.' , And lost the disadvantage of pulling. However, the above-mentioned shortcomings are resolved after the ratchet wrench is developed in the industry.

1233861 V. Description of the invention (2) ′ However, the structure and assembly of the ratchet wrench is time-consuming. Therefore, how to reciprocate the effect, that is, the present invention relates to the improvement of the structure, which mainly includes a wrench body, the wall edge surface should be abutted against the top end and the sexual body clip portion. The mouth of the sleeve is against the top and penetrates, and when it reaches the top, a plastic with elasticity is stuck on the shoulder element, and the cost of g is relatively increased. There is a plum wrench structure, which can be corrected. Two ^ The purpose of the effort required by the tea industry to receive ratchet wrenches. [Summary]: The structure of a hand tool is improved. At least one end of the hand tool includes a wrench body with a proper depth ring at the mouth of the plum sleeve and a plurality of ratchet teeth. There is a groove-shaped shoulder portion in the snapping action. The shoulder portion can be provided. The plastic system forms a smooth portion in the wrench body mold. The smooth portion is provided at the other end of the top portion, and the smooth portion. The hole diameter is slightly larger than the ratchet-toothed top, that is, the hole diameter of the smooth part of the present invention is also slightly larger than the width of the screwed part. By designing the smooth part slightly larger than the screwed part, the screwed part can be adjusted to accommodate the smoothness. When the wrench body is rotated, the phenomenon of idling will occur, so that the wrench body can quickly and smoothly achieve the reverse dislocation effect. In this way, it is an improved structure of the hand tool of the present invention. The structural effects of the structural improvement of the hand tool of the present invention are summarized as follows, so as to enable the reviewers to gain a better understanding of the present invention. The structural improvement of the hand tool of the present invention uses the tool provided on the inner edge of the mouth of the plum sleeve. The design of the ratchet against the top and the smooth part without ratchet can make the switch

1233861 V. Description of the invention (3) The hand body achieves a simple and fast reversing reset effect, while the unused plum wrench structure, because the inner edge of the sleeve mouth is provided with only a ratchet against the top, makes it difficult to reverse the reverse time of the plum wrench. Disadvantages: As mentioned above, the present invention designs the mouth of the plum sleeve as a ratcheting abutment on the top and a smooth portion without ratcheting, which can make the wrench body have a small angle of reversal and dislocation effect, which is conducive to the use of narrow spaces. In order to improve the structure of the conventional tortoise wrench, because the angle at which the sleeve is taken out and realigned with the screwing part is relatively large, the disadvantage of losing the torx wrench is not suitable for narrow spaces; further, the present invention facilitates the torch of the torch sleeve to the top A plastic body, by virtue of the resilient elasticity of the plastic body, the wrench body can be automatically lifted upward, so that the screwed part falls into the smooth part, so that the reverse rotation of the wrench body is faster and more labor-saving; furthermore, In the present invention, only a smooth part is provided in the mouth of the plum sleeve, so that the general plum wrench structure can achieve the same inversion as a ratchet wrench with a complicated structure and a high cost. In terms of cost, the effect of transposition is in fact economical. [Implementation method] The present invention relates to a structural improvement of a hand tool, please refer to the first to third figures. The structural improvement of this hand tool mainly includes: a wrench body (10), the wrench body (10) At least one end is provided with a plum sleeve opening portion (1 1), and the inner wall edge surface of the sleeve opening portion (1 1) is provided with a plurality of ratchet teeth (1 2) at an appropriate depth. ), And can achieve the snap-action effect of the screwing part, and the top (1 2) -end is provided with a groove-shaped shoulder (1 4),
