Description

Technical Field

[0001] The utility model relates to the field of screwdrivers, in particular to a screwdriver. Background Art

[0002] A screwdriver, also known as a screwdriver, screwdriver, screwdriver, or chisel, is a common tool used to turn screws into place. It has a thin, wedge-shaped head that fits into the slot or notch of the screw head. Turning it clockwise tightens the screw, while turning it counterclockwise loosens it. Screwdrivers come in various types, including flat-head, Phillips, and hexagonal. They all work on the principle of levers and axles.

[0003] In order to facilitate the use of force, existing screwdrivers are designed with anti-slip grooves on the handle to increase friction. However, since the handle is a long stick-shaped structure, it is not convenient to use force. When using it with force, the hand will quickly feel sore and uncomfortable. In addition, although the existing screwdrivers can be replaced with bits of different structures, the hexagonal bits corresponding to these bits are all of specific sizes, and the replacement range is limited. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a screwdriver to solve the technical problems that the existing screwdrivers are inconvenient to use for leverage and have a limited replacement range.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a screwdriver, comprising a main body, an inner head is provided at the bottom of the main body, a large-diameter hexagonal hole is provided at the bottom of the inner head, a sleeve that cooperates with the main body is detachably inserted into the outer side of the inner head, an outer head is provided at the bottom end of the sleeve, a small-diameter hexagonal hole is provided at the bottom of the outer head, an opening is provided inside the main body, and a slot corresponding to the opening is provided at the top of the main body, a top cover is detachably provided on the top of the main body, a connecting rod is provided at the bottom of the top cover, and the connecting rod extends movably into the interior of the opening, a rotating head is provided at the bottom end of the connecting rod, the rotating head can slide inside the opening, and the rotating head forms a movably fit with the slot.

[0006] By adopting the above technical solution, a detachable sleeve is installed on the outside of the inner head. The bottom end of the sleeve is an outer head. The inner head and the outer head correspond to two hexagonal holes with different apertures. The screwdriver bits of two sizes and different structures can be replaced here. When leverage is needed, pull up the top cover to bring out the connecting rod, and then rotate it to the side. In this way, the top cover and the connecting rod will form a leverage handle, which is convenient for leverage.

[0007] The utility model is further configured such that an insert block is provided inside the sleeve, and the insert block is matched with the large-diameter inner hexagonal hole.

[0008] By adopting the above technical solution, the sleeve is prevented from rotating when the outer head is used.

[0009] The present invention is further configured such that the outer side of the main body is provided with anti-slip lines.

[0010] By adopting the above technical solution, the hands can be prevented from slipping during normal use.

[0011] The present invention is further configured such that the slots run transversely through the top of the main body.

[0012] By adopting the above technical solution, the connecting rod can be rotated in both directions, which is convenient for use by both hands.

[0013] In summary, the present invention has the following beneficial effects:

[0014] 1. This utility model inserts a connecting rod into the interior of the main body. The top of the connecting rod is a top cover. In normal use, the top cover is pressed and the main body is rotated. When a force is needed, the top cover is pulled upward to bring out the connecting rod, and then rotated sideways. In this way, the top cover and the connecting rod will form a lever handle, which is convenient for leveraging.

[0015] 2. The utility model arranges a detachable sleeve on the outside of the inner head, and the bottom end of the sleeve is an outer head. The inner head and the outer head correspond to two hexagonal holes with different apertures. Here, screwdriver bits of two sizes and different structures can be replaced, and the replacement range is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] A screwdriver, such as Figure 1-7 As shown: it includes a main body 1, an inner head 2 is provided at the bottom of the main body 1, a large-diameter hexagonal hole 3 is opened at the bottom of the inner head 2, a sleeve 4 that matches the main body 1 is detachably inserted into the outer side of the inner head 2, and an outer head 5 is provided at the bottom end of the sleeve 4, and a small-diameter hexagonal hole 6 is opened at the bottom of the outer head 5.

[0027] When it is necessary to switch a screw bit of a specific small size, it is only necessary to plug and unplug it into the small-diameter hexagonal hole 6 on the outer head 5. When it is necessary to switch a screw bit of a specific large size, the sleeve 4 is unplugged to expose the inner head 2, and it is only necessary to plug and unplug it into the large-diameter hexagonal hole 3 on the inner head 2. The detachable inserting structure between the inner head 2 and the sleeve 4 can be tightly plugged in, so as to prevent the sleeve 4 from detaching during use. A certain amount of force is required to unplug the sleeve 4. An insert block 7 is provided inside the sleeve 4, and the insert block 7 cooperates with the large-diameter hexagonal hole 3. After the sleeve 4 is inserted, the insert block 7 is inserted into the large-diameter hexagonal hole 3, so as to prevent the sleeve 4 from rotating.

[0028] On the basis of the above structure, the screwdriver is further provided with an opening 8 inside the main body 1, and a slot 9 corresponding to the opening 8 is provided on the top of the main body 1. A detachable rotating sleeve on the top of the main body 1 is provided with a top cover 10, and a connecting rod 11 is provided at the bottom of the top cover 10, and the connecting rod 11 is movably extended into the interior of the opening 8. A rotating head 12 is provided at the bottom end of the connecting rod 11, and the rotating head 12 can slide inside the opening 8, and the rotating head 12 forms a movable fit with the slot 9.

[0029] During normal use, press the top cover 10 and rotate the main body 1 to use it. The outer side of the main body 1 is provided with anti-slip grooves to prevent the hand from slipping. When a force is needed, the top cover 10 is pulled upward, so that the connecting rod 11 can be brought out from the opening 8. When the bottom of the connecting rod 11 moves to the top of the opening 8, the rotating head 12 will be pressed by the slot 9, and then the connecting rod 11 is rotated sideways so that the connecting rod 11 is stuck in the slot 9. Figure 4As shown in the state, it is equivalent to adding a horizontal handle, which is convenient for use by leveraging. Since the slot 9 runs horizontally through the top of the main body 1, the connecting rod can be rotated left or right, so as to adapt to left-handed or right-handed use. After use, the connecting rod 11 and the top cover 10 can be reset by moving in the reverse direction.

[0030] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
