New description: [New technical field] This creation is about a hand tool replacement structure, in detail, it is about a detachable screwdriver tool, which has a replacement structure design for easy operation. It is convenient for the user to change the action. [Prior Art] Hand tools are common and necessary tools in the courts and work waste. Among them, screwdrivers are the most common. Because of their wide range of use, the domestic hand tools development system is quite mature and stable. Regardless of _ is the product type thief is the structural quality, but also the tree generation line, and the production of t-shirts in the past few years in order to make the general public to make (four) more system, so all kinds of secret or attached humanity function Tools have also been asked about the market. Please refer to the Republic of China Patent Application No. 8 9 2 1 8 0 4 3, "Removable Screwdriver Improved Structure", in which the main Wei-handle is provided with a recessed hole in the inside of the handle. The sleeve is provided with a through hole, the through hole is inserted into the through hole of the seat, and the side of the fixed seat is opened - the slot is formed by the slot. Extending into the perforation, and generating a t-pressure on the peripheral rod _ circumferential surface to position the screwdriver rod, the seat is fixed, the longitudinal direction of the slot is symmetrical to the axial direction of the perforation, and the two oblique portions of the longitudinal direction are respectively provided - a locking portion; the non-metallic material having a compressible and resilient elasticity is formed into a long plate shape, and each of the two ends of the symmetrical direction is provided with a positioning portion. The positioning portion can be positioned at the locking portion of the fixing seat. Upper, a pressing portion is protruded outwardly with respect to one side of the slot, and the pressing portion can be extended in the through hole. The conventional screwdriver structure has the effect of increasing the scope of application by replacing the screwdriver head. However, the replacement structure of the screwdriver head is too complicated, and the manufacturer needs more steps to manufacture and assemble, and the material cost is also Higher and more complicated structures are prone to failures, especially the replacement structure of 5 M311542, such as screwdrivers. It is easy to use hand tools for more messy workplaces, but it is quite complicated to drop collisions. Practical use causes failures, causing inconvenience to the user, so as a whole, sex is still necessary for improvement. [New content] The main purpose of this creation is to provide a replacement structure for the fresh jade, and to improve the conventional manual replacement structure, which is complicated and easy to malfunction. In order to achieve the above-mentioned creative purpose, the present invention includes a grip portion and a sub-head that can replace different types of screwdriver heads to achieve a multi-purpose effect. The screwdriver head is provided with a buckle. a slot, the handle portion is axially provided with a receiving hole, the receiving hole sleeve is provided with a fixing member, the fixing member has a positioning hole, and the adjusting member is sleeved, and the difficult member has a card abutting block. The card abutting block can be inserted into the positioning slot by the slot of the fixing member, and is buckled to the buckle of the screwdriver, so that the screwdriver can be used to locate the county; the structure of the above-mentioned structure can be used when the user needs to replace the screwdriver head. Rotate the adjustment member so that the card key of the adjustment member is reduced. It is necessary to slap the head, wait for the money to complete the secret, and then reset the light member, and then combine the positioning of the screwdriver head with the grip portion. _ The overall structure of this creation is relatively simple ^, the cost is low and the system is suitable for tolerance, and it is not difficult or damaged, and it is easy to make it. Therefore, this creation is a kind of practical and progressive creation, which is quite worthwhile. The industry has promoted it and made it public. [Embodiment] The present invention relates to a hand tool replacement structure, as shown in the first to fourth figures. The hand-wound replacement structure mainly includes a handle portion (worker) and a sub-head ( 2(5), an adjustment piece (3 〇) and a “fixing piece (4 Q), the handle part (1 Q) can be used with a variety of different screwdriver heads (20) to increase the overall scope of application. Multi-purpose effect; 6 M311542 The screwdriver head (2 Ο) has a - - - - - - - - - - - - - - - - - - - - - - - - - - - - A locking groove (23) is formed between (2 2), wherein the pulling end (21) is in the shape of a letter in the embodiment, and may of course be formed into a cross shape, a star π, a 丄, an equal shape.
